by the way @thc013, hopefully you could share the kernel and android tv compilation steps, hopefully someone could continue maintaining this image if you are not able to commit to this project anymore 
[ROM] ROCK 5B Android 12.1 rkr10 GoogleTV
Yeah, standby mode doesnât work. The power button did work for me, but keyboard or the chromecast remote did not (it disconnects on sleep anyway). Also, HDMI-CEC doesnât seem to work (but it may be the cable).
Would be useful to check if the Rock5B supports standby mode at all
I got V4 flashed to emmc, runs OK, but no sound though HDMI
any suggestions?
Is it possible to add more wifi driver to this build?
I have one rtl8852be module, which from my lenovo laptop.
installed it to rock5b, didnât work
on linux, I got this info:
03:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b852]
Subsystem: Lenovo Device [17aa:4853]
I think itâs subsystem ID differ from Radxa ones
In sound settings change the output to HDMI Bitstream
I have the same issue. I did this and it didnt fix it

Why couldnât you just use a USB type A to USB type C cable instead?
A to A cable is very uncommon
I guess it could be A to C if your computer can provide enough power for the board (unlikely, although 5V 3A could suffice). I managed to boot it even with a 5V 1.5A chromecast power supply, but it restarted when I tried to do anything more than looking at the screen
But I am asking what is the actual hardware difference between a a to C cable and an A to A cable with a type C OTG adapter?
how exactly would it be any different , you are still making a A to C connection
but A to A cables are rare AF , I just happen to have one though,someplace
Not an expert here but I think A2C & C2C are supposed to have a resistor on one end to prevent two devices from sending power to one another - if you try connecting 2 phones using a C2C cable, the direction seems to matter (even though both ends look the same).
A2A wouldnât have it and could damage old dumb devices. I donât know much about this though
ow hadânt posted v5 here

Thanks
I tried solving the file access problem by installing and trying many file managers (including Google Files). I tried the native Android Files apk (com.android.documentsui) that you can get from here for example: https://apkcombo.com/files/com.android.documentsui/ but nothing worked. I cannot manage files in any app that wants to read outside its own directory.
Right now I think this is a lost cause and Android TV is dead. Has anyone had any success with doing this (ie for example trying to add a directory in Redream or AetherSX2)? Does it work on V5?
With Files (com.android.documentsui) installed I am at least getting a dialog box letting me choose âFilesâ or âAction stubâ. Files does nothing and stub prints out âYou have no app that can do thisâ. In AetherSX2 you can navigate using different file managers, e.g. MiXplorer, but when you choose a file it does not get added in the app.
lost hdmi audio. no kodi or other apps that were on v4 build. xbox controller wont connect bluetooth. but wired works. redream and other apps work. i can find roms. before it wouldnt let me access. ethernet works. bluetooth works with remote.

thnx for the link M. on discord
ow and googletv is pretty alive 
, it is just you want something what isnt solved or fix easy

A to C get no CC signal, which can make power supply output 9V/12V
ehh this i a android topic not power related

and second attempt of v3 so 2x3 = V6
this is very expermimental and could just as v3 have no hdmi who knows
https://drive.google.com/file/d/102f-GP6hWFKMu-Pm_dgIq8O0Fy9H2d46/view?usp=share_link
i updated the kernel with a more recent one, on v3 i included the wrong gpu firmware corrected that and used the mali userspace driver from the rkr12 rom . wifi could be a complete mess i did little fighting with the rtl8852be module 
it looks a little lot of firmwares and you dont have to udate if you have one where you can live with ,it just a work in progress and info helps me a lot , it is not always 1 fix for all boards . thnx
here a video from the same firmware on a h96_max_v58 and no i am not from brazil and dont know what he is saying but the first half hour is about maskrom , after 30min it is more interesting
thanks for update
but sadly, wifi still cannot be turned on
wich you tried ? and you have a log ?
v5 version flashed
got this from adb shell
