Anbernic RG552 AOSP 9.0 Beta #15 (Bugfixes, better performance, 16:9 HDMI output and QoL improvements)

Can anyone help me? I read over the instructions on how to root this thing but I'm kind of lost. Whenever i rooted my phone i had to patch a boot room in order for it to work. So I'm not sure how i activate Magisk, because i installed the app and it says that it requires an additional setup. What am i doing wrong here?

lotek85

I tried using the SDFlash method, and I got a pink background with email and contacts on the main screen. Did I do something wrong?

No problem glad it's up and running!

Black-Seraph

That was the problem, it is installing now, i´m sure it will work now. Thanks a lot for your quick assistance.

Glenn Shoemake

You aren't meant to unzip the Gapps package.

Black-Seraph

Sorry again, but I cannot even find the Hanburger memu, is this in Android? I found that I can get into TWRP by holding down function button and Power, but when I go to Install, and select the GApps folder that I copied over from the pico opengaps it does not give me an option to install. When I check the contents inside they are all tar.lz files and TWRP only supports image or zip files. I only installed Android 9 from the sdflash method and nothing else if that helps.

Glenn Shoemake

Try opening Magisk, open the hamburger menu, go to Modules, open the ... menu and pick Reboot to Recovery.

Black-Seraph

Sorry for being dense, but could you please provide some further instructions on how to deploy the Google Play Store. I downloaded the OpenGaps program as you have suggested, but have no idea how to boot into TWRP and install this. I do have a clean Android 9 Black Seraph image now on my RG552 but really need the play store.

Glenn Shoemake

You can boot into Android and use ADB to reboot into TWRP as well. The adb command is "adb reboot recovery".

Black-Seraph

I just installed this, and the android is working, but I tried getting into TWRP (holding F+power) but it only just launches Android. Any tips for making sure TWRP installed?

Ryan Kearns

Has anyone else tried running dead cells using BS Android 9 os? This game worked great for two runs, then 90% of the button controls stopped working. Found a reddit thread from a year ago with folks experiencing this issue but no resolution other than one person mentioning "turning off accessibility features".

William Gadberry

Happy to hear you made it!

Black-Seraph

Ended up going that route. Worked perfectly, thank you

Dylan Tayag

Do yourself a favor and use the SDFlash method for installation. It requires a Micro SD card but it's a lot easier to handle for beginners.

Black-Seraph

I followed all of the steps, ran the bat file and continued to hit yes many times... but when it was all done, the device did not reboot itself. Waited a couple of hours with no luck. Now my device does not boot on the android side. Any tips?

Dylan Tayag

Quality control issues? Did you two try getting in touch with Anbernic yet? Maybe they can provide some spare parts. Try tagging IdeaYu, their sales manager on Twitter.

Black-Seraph

hi, beware since it might hardware related; got the same issue when running Jelos, but ended up shacking the device a bit (when off of course) and fan restarted! it seems as if it gets somehow stuck.

matparn

If you use the SDFlash installation method then yes. All you need to do is use a disk imaging software of choice to write the provided image to a MicroSD card. All of this is explained in the included README file though.

Black-Seraph

Can you use a Mac to install this on to the RG552?

Chris Green

That's the first I've heard about something like this.

Black-Seraph

Anyone else having issue with their fan after updating to this version of 9.0? My Fan worked fine on the stock anbernic provided Android 11 firmware, now even on the highest CPU setting and fan on HIGH, it never turns on. Any known issues?

Brent Nelson

You're welcome!

Black-Seraph

Cool... Thank you very much for shortening the rooting time. I really appreciate your work.

Djoelax Djantjox

Android 8.1 and 9.0 builds will auto install TWRP. 11 builds run stock recovery at this point.

Black-Seraph

Awesome... 1st time stuck on the android logo, but after repeating the ritual from the beginning it went smoothly after clearing the data. Although confused because there is no browser application & after installing the gaps everything is ok. Btw, in this RG 552 the TWRP already exists from the start or after installing this ROM? Because I remember never installed TWRP. Great job & thanks.

Djoelax Djantjox

It's bundled with the MaskROM files.

Black-Seraph

downloaded all files but was missing Driver.exe

Sage Tang

It's been a busy month, but yes, a new build is coming soon. It's currently going through testing to ensure everything works properly. Will be out this month, stay tuned!

Black-Seraph

I have to admit I never touched Substratum so there's nothing I could tell you about it or it's inner workings.

Black-Seraph

I don't know if you're familiar with the substratum theming engine but any idea why it doesn't work on this build of android?

William Wright

Hello, i just resubbed after a while of not having subbed and it shows this is the most recent post but its the build im already using. Are you still updating/plan to update this build?

dylan hooey

That's much appreciated! Glad everything worked out!

Black-Seraph

So glad to have joined Your Patreon and to support You. I've installed Beta 15 in less than 30 minutes and now my belowed Anbernic RG552 is a real blast to use. After a long day of work, being on the couch with all those beautiful games is so relaxing. Thanks to You man, I will continue to support You in the next months to help You out. Good job really.

Antonio De Nardis

1. They are. 2. There is. 3. About 1.5% per hour of sleep.

Black-Seraph

Hello, first of all thank you for the update i ended up subbing twice here . I have 3 questions. 1. i haven't gone ahead and installed this yet but are twrp and magisk included in the update? 2. Any plans for an android 12 update ? I've seen another dev work on that and it looks like there's actually some more room for performance gains. 3. how is the idling/sleep knowing the RK3399 is power hungry?

William Wright

I will.

Black-Seraph

Black-Seraph: just message me on discord when you get done or started on the joysticks deadzone i barely get on patreon

Michael Snipes

Black-Seraph: thanks

Michael Snipes

Not yet. It's in my work-queue.

Black-Seraph

Black-Seraph: any news on joys deadzone fix

Michael Snipes

No problem. It's the overall better Remote Play app anyway.

Black-Seraph

Awesome. Thanks.

Niko

Most people use Chiaki now-a-days because Remote Play tries to lock you into using Sony gamepads only.

Black-Seraph

Anyone else have an issue with PS Remote Play app? Instantly closes with “something went wrong” (88001003).. Cheers.

Niko

Unless something major crops up, yes. I will bugfix anything people find & report though. (And there's more RG552 stuff in the works of course, bringing some variety.)

Black-Seraph

Excellent work, thank you. Definitely more stable than stock 7.1.. Don’t think I’ve had one crash. Is this likely to be the final 9.0 release?

Niko

Not that strange to me TBH. This is why RetroArch has different versions of MAME on offer. Some newer versions of the emulator just perform worse than older ones.

Black-Seraph

Ok thanks, I'll try to launch a game from the internal memory to see if it changes something. But it's very strange for me

Antonio D'Alonzo

I can't really tell you anything specific about Redream but the driver hasn't changed at all since Android 7. The latest Midgard driver available for the Mali T860 is r18p0, which we have been using from the start and still are.

Black-Seraph

I have an issue: Redream has terrible performances, even with overclock. With the same settings it was working fullspeed on the stock Android 7. I'm not expert, but are there issues with Vulkan? Flycast too only works well with the OpenGL renderer and with Vulkan is slow. It's strange because for example Yabasanshiro performances have increased from stock Android 7 to your Android 9. Only Redream has terrible performances.

Antonio D'Alonzo

To make it short and sweet: Brighter: No. Hardware limitation. Lower: Yes, but only slightly and I've found that it really doesn't make enough of a difference. :( About the key mapper: Yes, it's possible and something I'm considering but I'm currently thinking about fully rewriting the key mapper to be self-contained in a framework patch for inputflinger. The reason for that is that 1. It would be fully portable between different devices and 2. It wouldn't require a custom kernel driver to function, which is a big help with closed kernel source devices like the Moqi & PowKiddy line-up.

Black-Seraph

Hello! First off - thanks for all your hard work, these updates have basically made the 552 into the handheld i'd hoped it could be! A couple of requests, if i may: Would it be possible to have both lower and brighter screen brightness settings, or are they unchangeable? I play it in pitch black and sunlight often enough that i thought i'd ask. Is there a way to remove unused buttons from the keymapper? There's been a couple of times i'd have liked to have only a handful set and the rest do nothing. Thanks again!

Tom Keegan

I was able to complete the installation to the end. Thank you!

にょぴー も

Sorry...I had mistaken 8.1 for 9. I am embarrassed...

にょぴー も

Hello. I have installed AOSP for the first time, Android 8.1 works and Magisk installation seems to be successful, but when I boot with TWRP and run the installation of open_gapps-am64-8.1-pico-20220215.zip, I get an Error Code: 20 is displayed and the installation fails. What are the possible causes?

にょぴー も

We're on the same server so you can just send a DM either way.

Black-Seraph

Im on discord if u have that but u have to add me as friend

Michael Snipes

Their isnt a way to upload images on mine and i dont know how to link with image host

Michael Snipes

There's a button to upload images on mine. But you could just upload them to any image host of your choice and link me to it too.

Black-Seraph

Black-Seraph: there is no option to send screenshots

Michael Snipes

Yea both my joysticks have deazones

Michael Snipes

How do i send screenshots here?

Michael Snipes

Can you send me link to right one to download

Michael Snipes

Sure ill do that when i get home

Michael Snipes

I haven't had any such issues on my RG552 yet. Gamepad tester gives me fairly good analog stick output. The only way to counteract analog stick deadzones is by adding a filtering algorithm into inputflinger. I had to do that with GPD XP & PowKiddy X18S because out-of-factory all of them had deadzones. Mind installing gamepad tester, going into the analog stick axis menu, circling your analog sticks, then sending a screenshot over so I can compare our analog sticks?

Black-Seraph

No prob: may i ask what do u recommend for joystick deadzones, i know thats normal but is there a way to fix that cause it weird when playing games when it makes ur character walk slow in one direction and fast in the other lol

Michael Snipes

I'm putting it on my list. Thanks for reporting it!

Black-Seraph

One is truck simulator, the other is bus simulator, really those are the main ones i play

Michael Snipes

Mind telling me the game so I can take a look myself?

Black-Seraph

I do have issues with bith joysticks but i think thats normal, its a deadzone on them for some reason, like i can walk fast in one direction but when i go the other way its real slow, alot of people say thats normal otherwise joysticks will start to wonder well move on there on is their a way or a app that can fix joystick deadzones

Michael Snipes

Its really to many to list for me on the andriod side, but alot of times the buttons will act weird when playing emulators when i use the keymapper, like they wont respond until i reset keymapper, some andriod games i play are simulators that i get from play store have the on screen buttons so i use the keymapper and arrange the buttons onto the touch screen buttons and they quit working after a few mins, again this also affects my regular "nes and snes and gb and gbc and all other emulator, i explained it the best i can again i dont use keymapper anymore cuz the issues and bugs it has.

Michael Snipes

Could you tell me what issues and in what games?

Black-Seraph

The keymapper causes issues on some andriod games i play.

Michael Snipes

It works for me every time. Mind telling me where you're having issues with it?

Black-Seraph

I dont use the keymapper, it doesnt work half the time, so i never press the F key anymore

Michael Snipes

Agreed, i hope there is a better option with the next update. It doesn't work very well with some games either.

aaron jackson

Is there any chance to update keymapper? It looks ugly and isn't very comfortable. I miss an option to hide unused keys for example.

d3rt0xx

The thing is: nothing changed on my end. And if it worked on the previous AmberElec build, and the only change since then was on the AmberElec side of things, then it could very much be that some change there might be causing this. I hope I can find something useful to rectify this tonight.

Black-Seraph

Thank you. If it helps, Android 9 loads the Jelos partition as read-only. But mount the 351elec as read/write. Although that doesn't explain why it only destroys the latest version (prerelease) of 351elec/amberelec.

Leonardo Cruz

I just got a message on Discord regarding this as well, asking if there was some kind of whitelist in place for "allowing" other OS installations. There's nothing of the sort there, so I'm not really sure what changed with the latest AmberElec versions that causes such an issue. I intend to take a look at their latest version tonight to see where the issue might be.

Black-Seraph

Hi there! We are doing some multiboot testing of your version of Android 9 and the linux versions (Amberelec, Batocera and Jelos). We don't know why we were able to boot Android 9, 351ELEC, Jelos and Batocera interchangeably and everything works great. But since the last update of 351ELEC, which was renamed Amberelec, when we insert that SD, Android destroys the partition. It does not happen if we insert the same SD with previous versions of Amberelec, Jelos or Batocera. Everything works perfectly. But when we insert the SD with the latest version of Amberelec(351ELEC) the partition is destroyed. The SD is empty with only a "LOST.DIR" folder. Do you know why this could happen? Thank you very much.

Leonardo Cruz

I can't believe a windows error message was spot on this time. I'm glad it worked out!

Black-Seraph

YES i just got it working ! haha. so yeah just restart your computer and reinstall the drivers and do everything again and you should be right as rain

Robert Soliz

Sorry to hear that. If you need me to take a look at it in person hit me up on Discord later tomorrow. I'm sure we can fix it back up.

Black-Seraph

so i just bricked mine too :/ i tried out android 11 update and didnt like it so i wanted to get back to this build. I've been updating since build 1 and never had a problem. The process ended and now its just black screen with the fan. Shit lol. gonna try to restart everything and see if it works. black seraph remind me to never try anything else except your work. haha

Robert Soliz

Does it get picked up at all in the device manager when you do the MaskROM button combo?

Black-Seraph

Mine bricked as well, and the worst part is I can't get my PC to recognize it anymore. Just boots to an anbernic screen and nothing else happens. What can I do??

Adam Coomes

Same thing happened to me a while back. Which is why I've never been a fan of this update method. Too many things that can go wrong during the process and relying upon Windows to detect and stay connected to the device without disconnecting during a critical writing phase and potentially bricking the device. Why this image can't simply just be flashed to a card is beyond me. Reboot your PC, re-install the drivers on your computer, and try again from a clean slate. Are you able to boot into TWRP? Took me a few times. Good luck, bud. :)

Nicky Santoro

No problem. You're welcome

d3rt0xx

D3rt0xx: thanks for everything it works like a charm, love my new navbar layouts now, also added a few other tweaks like mario bros on my navbar, just loving it.

Michael Snipes

I got a brick in my RG552 trying to update android. Now, it doesn't boot, the only thing it does is start the fan, but the screen doesn't turn on. I can't get into recovery mode and my computer doesn't detect anything when I plug the usb cable. I think the problem must be something related to the bootloader. Is there something I can do to get it working again?

almofe

Install zip in Magisk Manager

d3rt0xx

Don't wana hide it, cuz when I used physical buttons it would exist my games

Michael Snipes

D3rt0xx what do you use to install lsposed, it's a zip file and yeah navbar is ok the only issues I have is it disappears cuz alot of apps change it's colors and white background with white nav buttons dont mix

Michael Snipes

Heho is it not possible to hide the navigationbar?

Michael Kinc

1. Install latest LSPosed (https://github.com/LSPosed/LSPosed/releases) 2. Reboot device 3. Install latest GravityBox module for Android 9 (https://github.com/GravityBox/GravityBox/releases/tag/v9.2.1_p) 4. Activate Module in LSPosed app 5. Reboot device and profit 💪🏻

d3rt0xx

How do you install that where do u get it sorry for so many questions, can you tell me what i need

Michael Snipes

One message is enough Snipes 😉 You have to install Xposed Framework first. I recommend LSposed

d3rt0xx

D3RT0XX: how do i install that?

Michael Snipes

I tryed installing gravitybox xposed module and it says error parshing package

Michael Snipes

D3rt0xx where do i get that

Michael Snipes

Try GravityBox Xposed-Module. idk if BlackSeraph hardmod the navbar-framework, but GravityBox works well in vanilla aosp

d3rt0xx

has anyone come up with a way to customize the navbar?

Michael Snipes

WOW, works great when you follow the instructions, SNES9x emulator Runs perfectly, havent tried the N64 emulators yet and I'm completely lost on the whole Arch Retro thing, but learning i guess, not even sure why i would need to boot into the linux again, this is great. thanks

Edwin

That's entirely up to each and every app. The OS has a working vibration HAL which means apps can make use of the rumble motors. If they don't though then there's little I can do about it.

Black-Seraph

Hi black seraph , is there anyway to get vibration on the Xbox stream ? ie rumble effect ? Through remote play not xcloud ?

Danny Brown

Me too. After getting a taste of the performance boost in emulation and remarkably increased battery life over the weekend when I tried the official 11, it can't happen soon enough. The only reason I went back to this build is because I need gapps, play, and root folder access.

Nicky Santoro

I look forward to your firmware version with the official Android 11 that anbernic released <3

Franko Garcia

Where did u get andriod 11

Michael Snipes

I had posted a follow-up question to the xbox controller issue, but it got removed. Anyways...just wanted to say, when I had flashed over to Android 11 last Friday, everything worked just fine. But yesterday when I flashed back over to this image, it was back to the same problem. xbox controller will rumble when connected, but no light or any input at all. So, seeing as how it appears that it's not device related, I was trying to report a possible bug as at this point, I can't imagine I'm the only one.

Nicky Santoro

I'm the only one capable of doing so other than the original writer and Patreon themselves and I haven't touched it so it must be one of the other two. Hit the wrong button by chance maybe? If not just repost the question real quick.

Black-Seraph

Nicky Santoro

Install 7zip, download all files (001, 002, 003) multi select them all and extract them

Rich Silva

shows Maskrom file#001is password protected; any suggestions?

Javier Bustamante

I havent had any issues at all, just want some navbar customizations, also does anyone know what that app "DEVICETEST" is? Mine keeps popping up randomly every now a then with a closed error message

Michael Snipes

Navbar options would be great. I'm loving this rom so far. Haven't had any issues.

Rich Silva

Black-Seraph: would you be able to add a way to customize the navbar, i got a app on it but the buttons half the time wont show up unless you rotate the screen, i also got a rotating app the rotates the screen how u want it when you load a app up, you just have to set it how u want it

Michael Snipes

I'm working on it but I'm not THAT fast. ;)

Black-Seraph

Any news on any new features for the RG552

Michael Snipes

Also got Gapps installed :D I havent wasted this much time modding an Android device in years, so exciting lol

Rich Silva

Yup

Joshua Boylan

I got it, thanks to your help!

Joshua Boylan

Thanks, where do I find that?

Rich Silva

Reinstall 7.1 then upgrade

Joshua Boylan

Install anbernic v1.13 7.1 update then upgrade to 9

Joshua Boylan

How to go from the Android 11, to Android 9?

Rich Silva

Yes it is. And Android always formats as FAT32. You have to use a PC if you wish to format your card into another format.

Black-Seraph

Is xFat still supported? I'm getting errors. When I had Android format the sd card it formatted it in FAT32.

Jeff

Thanks , it literally looks exactly the same as the realtek one same colours etc

Danny Brown

On paper they should. Just have to make sure they stay within the 3.3v power envelope.

Black-Seraph

Hi black seraph , would any dongle with the RTL8821CU chip work ok ? As struggling to find a realtek branded dongle here in the UK on Amazon ?

Danny Brown

Wow. Now that was unexpected.

Fabrice Usieto

Hi there, there is an official Android 11 update...

Fabrice Usieto

Cool ... Thank you boss!

Marcio Kanashiro

Just press the F button. It's included.

Black-Seraph

XBOX controllers work just fine. Mind telling me a bit more about yours? Maybe you can send me the lsusb output while it's connected (if it's plugged in via USB) or a dumpsys input output if it's connected via Bluetooth?

Black-Seraph

Hey Black, Is there a way to have/install the button mapping for Android games?

Marcio Kanashiro

Hi, thanks for this update. Was just wondering when xbox controllers will be supported? Sony DS4 and DS5 controllers I've never had issue with, but I've never gotten any xbox controller to work. Would be nice as that's the preferred controller for xbox live and most other platforms. Thanks again for all your hard work!

Nicky Santoro

That sounds like a plausible explanation. You could just force close the app though to verify.

Black-Seraph

alright, i'll try other DACs, and do more testing ! It may be related to Neutron audioplayer not releasing the sound device when i close it as it uses it in exclusive mode.

Ciarán Leòghann

No idea. The only USB audio device I have to test these things is a set of AKG earbuds that I got as a freebie somewhere. It's what I use to test USB audio output and that one works regardless of what app I try them with.

Black-Seraph

yes i figured that out, just wanted to avoid installing anything, so the linux route was the most convenient. Just a small note, i used a usb DAC (dongle, Lotoo PAW S1), and while it works flawlessly with audiophile android players (Neutron, UAPP) i get no sound from emulators, any idea ? i'd love to use it with emulators as the RG552 built in jack output is terrible, lots of hissing and interferences noises.

Ciarán Leòghann

Windows users need to install the drivers first. Linux distros tend to have the required drivers already.

Black-Seraph

First time i flash your rom on my RG552 and while i failed running it on Windows, it worked like a charm on linux (Debian). Thank you so much for sharing your work ! cheers.

Ciarán Leòghann

I don't suggest doing this (IMO internal storage conversation brings more issues than it solves) but you could just convert them to internal storage in the storage settings menu.

Black-Seraph

I'm glad to hear that! Game Pass is very picky about WiFi signal quality. Way more than Stadia, Shadow, GeForce Now, Moonlight & Parsec.

Black-Seraph

This version plus the wifi/bt mod made xCloud gaming flawless, thanks!

Michael

Is there any way to format sd-card to internal storage? Or an option to move Android apps/games to sd-card?

d3rt0xx

Did you install the included driver?

Black-Seraph

Can't get it to work as my computer doesn't detect the RG 552 as anything but an "unknown device", not a "MaskROM / Rockchip" device. Any suggestions?

DuDuOsun

I'm happy to hear it all worked out!

Black-Seraph

Black, thank you very much, I bought the adapter you indicated with RTL8821CU, the Bluetooh and the 5ghz WIFI worked perfectly, I found it in the free market, I am from Brazil and I didn't want to wait for Aliexpress's time, but I leave my thanks to you

Haroldo Junior

No problem. Depending on your region you might have to source it from another buyer and / or website though. These are also available from a variety of AliExpress sellers, but they will take longer to arrive than ordering them straight from Amazon for example.

Black-Seraph

Thanks Black

Haroldo Junior

Check the RG552 WiFi & BT chip installation tutorial post. The suggested part is listed right there. Edit: I dug it out for you. https://amzn.to/3DzPtnD

Black-Seraph

I apologize, but I couldn't understand what exactly the models compatible with the RG552 would be, I was really in doubt about it, could you please tell me where exactly the compatible model is? I looked at all the posts, but I didn't find exactly what the models compatible with the RG552 would be

Haroldo Junior

Check the tutorial post carefully. The right adapter is linked there.

Black-Seraph

Hello, I need indications of a Bluetooth adapter with 5ghz wifi that works on the RG552, as all the Bluetooth adapters I tested did not work. I did your last update and started to emulate 3DS, but still not with good quality, ps2 some games are already running and several gamecube games are good, but I need to know which Bluetooth adapters with 5ghz wifi that work, thank you for your attention.

Haroldo Junior

Download all files into the same folder, then extract the 001 part with 7zip.

Black-Seraph

Hi Black-Seraph, first time doing this for my rg552. I am trying to extract the files after I download them but it keeps saying that cannot be opened as an archive. Not sure what I am doing wrong but it wont extract.

Zachary Medellin

Did you measure the voltage on that pin with a multimeter? That way you can know for sure if it's broken or not. You should be seeing close to 5v on it. As for alternative solder locations: There are some but if this one gives you trouble already I feel bad sending you to the "next" one, as that one is more difficult to solder.

Black-Seraph

So i did a poor job soldering.. turns out my iron was not hot enough.. didn't realize this until the end. I cant tell but I may have damaged this (VCC?) pad.. is there another place i can solder to? https://imgur.com/a/bpIHMi5

If it boots into the recovery then that means you have no USB connection at all. Check your cable and USB port.

I'm having trouble flashing the maskrom files for the first time - I am on Windows 10, I run the driver installer from the Driver folder, connect the RG552 as instructed, and boot with Volume+/F/Power. The device does not show up in Device Manager as a Rockchip maskrom device, and it only goes to standard recovery mode menu on the screen. When I run install.bat, I get a few messages ending in 'nul' before the terminal window quits out, and nothing happens. Any clues to what I am doing wrong would be helpful? EDIT: An update, the previous failed attempts I was using a USB-A to USB-C cable (two different ones actually), when I switched to the USB-C to USB-C that came with the RG552, the process appears to go ahead, it's installing now, and I will update if anything else goes awry, but I thought it would be helpful for everyone to know that apparently only the USB C to C cable is working in my case.

Seems to be a bug in the AOSP base. It's on my to-do list. For now setting a dark wallpaper does the same thing and forces the system into dark mode.

Black-Seraph

I see dark mode in your picture, but even when I select dark mode, nothing happens. Any ideas why this is not working?

Jason Andreas

I'm not sure I follow. What's the issue? Got a picture maybe?

Black-Seraph

Hi Black Seraph, all improvements are great but I have just 1 issue, once I connnect the RG552 to the TV with HDMI, the screen cut all borders, even trying to adjust aspect ratio didn't work... I had to install an app to adjust manually resolution, borders and other stuff but is not the best solution. Any idea about what could happend?

Martin Gallardo

Black-Seraph: If i may ask what are new things i also customized my nav bar and rotation changes with rooted apps, instead of my normal nav buttons i can now add photos or different icons and animations, and my rotation app changes the app either in landscape or portriat now, its a per app setting that u can choose i also have a volume increaser and a working calling and texting app on it and custom volume bars.

Michael Snipes

I'm trying a few new things with it at the moment but for now I intend to park it at Android 9 for a bit.

Black-Seraph

Black-Seraph: is their anything else coming for the rg552, just wondering

Michael Snipes

All. Put them in the same folder, then extract the 001 part. You will get a ZIP file out of that. That's the one you flash in TWRP.

Black-Seraph

Ah thank you buddy , which twrp file do I need ?

Danny Brown

Make sure both the Android install ZIP and the OpenGapps ZIP are stored on your device somewhere, then turn the device off and unplug all cables from it. Now hold down the F button while turning it on, you'll end up in the TWRP recovery main menu. Tap on install and select the Android ZIP first, then choose to add an additional ZIP and select the OpenGapps ZIP. Finally swipe to install.

Black-Seraph

Hi black seraph how do you install from twrp again ?

Danny Brown

Kk

Michael Snipes

If your device is running stock then a MaskROM install is the only way. Once you're running my firmware you can install follow-up updates via TWRP straight from the device.

Black-Seraph

So i have to have pc for the first time, which install do you recommend on fully stocked rg552

Michael Snipes

You can't.

Black-Seraph

Black-Seraph: i got another RG552, its fully stock and cant use my pc to upgrade or install the latest andriod you have cause my usb ports went out, havent had time to fix it, is there a way to root or install from sd card, i already downloaded all maskrom and twrp files along with the correct gapps, can you explain how to do this without pc.

Michael Snipes

I'll take a look but no promises.

Black-Seraph

Is there anything you can do about how noisy the headphone jack output is? It does it in stock android and jelos too so maybe it's just a crappy dac, amp or whatever?

Robert Gamble

No. There's no underfill on these.

Black-Seraph

Any chance some models have the wifi chip glued on? I can't seem to get anything under that wifi chip to pry it up and my soldering iron has yet to pick up any solder. Photo: https://imgur.com/a/1I58AjI

Simon W. Jackson

Yes. Enable the toggle and apps will be forced into landscape. Some apps might crash though, which is why it's been made a toggle.

Black-Seraph

Hi! This is what we were talking about? So all the apps are already put in landscape mode? :)

Alber

Cool thanks dude

Danny Brown

Wired: yes. Bluetooth wireless: only if you do the chip swap mod.

Black-Seraph

Hi black seraph , would I be able to use a headset with the rg552 with Xbox remote play ?

Danny Brown

If you look on the xcloud subreddit you'll find that many people have this issue spanning over countless devices. Every other streaming app has code to handle frame drops, but game pass doesn't and just freezes when that happens.

Black-Seraph

Ok thank you. I was wondering. Stadia and Luna work great on the tv. I didn’t know game pass was that finicky since I have only tested it on the rg552 since Firetv doesn’t support it. Keep up the great work. We all appreciate what you do. Hopefully Microsoft figures it out once the app comes out of beta. 👍

Yoan Herrera

You don't need to wipe the cache. Just select the AOSP ZIP as your first and then OpenGapps ZIP as your second ZIP and swipe to install. Game Pass works fine btw, but it's one of those apps that needs a PERFECT internet connection. The instant it drops a single frame the app freezes... It's not the device's fault. I went to great lengths to look into and debug this issue and every single person I looked into had some kind of internet connectivity issue while it "just worked" on my end and everyone else who had a reliable home WiFi + internet connection. :(

Black-Seraph

Use a very thin object as a wedge and start desoldering / heating the bottom right pin first. Using your makeshift wedge and your iron work your way up the right hand side and the chip should start lifting, flipping to the left like a book. Don't worry about the two pins on the left hand side of the chip. Even if you were to lift the trace on those two you wouldn't cause any damage. The modification would still work. Once the right side is lifted just hold the chip and desoldering the last two pins on the left side. Tin the pads afterwards and you're good to solder the new chip in.

Black-Seraph

Been having a lot of issues with Xbox pass. Freezes. Disconnects. Did a tether install a few versions back and twrt upgrades the last couple. Any suggestions? Twrt upgrades are just select install and the min the zip correct? Reinstall gaps and wipe cache.

Yoan Herrera

I'm trying to desolder the RTL8188FU from the device but I'm not making any progress. It's almost like it doesn't have any solder to be removed. Do you have any advice on how you removed the chip?

Simon W. Jackson

Any dismissal should work.

Black-Seraph

Got ya i hit clear so i shuld swipe them

Michael Snipes

You just swipe them away once. The system will remember that and not show them to you for that memory card again.

Black-Seraph

How do you turn off the memory card notifications, it says they cant be turned off

Michael Snipes

Kk

Michael Snipes

It does nothing. It's a leftover thing from Android 4.4 times.

Black-Seraph

Do we wipe cache/dalvik if we want, wat does that do
