Hello Konsta,
of course I installed OpenGapps; that's the prerequisite for being able to install the Playstore and other apps at all... at least that's how I understood it.
Apps that are not offered in the Playstore, I tried to install with X-plore (apk files) worked in many cases.

My question was how I can sort the start page a bit nicer (create folders; arrange the order of the apps).

I've already read something about replacing the launcher, whether I can find it again is another problem ;-)
. But if I replace the gapps launcher, will the TV apps still work and be displayed?

. IIRC - what does this mean?

. and another question about PrimeVideo App:
I installed version 3.0.318.11255 here, it is not displayed on the start page, but I can start it via Settings/Apps/Open.
how do I get such apps on the start page and others away from the start page?

Greetings
No, it's not necessary to install gapps to install other applications. You can sideload .apk files as discussed before (or sideload an alternative app store such as F-Droid or Aurora and use it install apps). Certain applications requiring Google services to run is different story of course.

If you type IIRC to Google search it will give you the definition: abbreviation. if I remember correctly; if I recall correctly.

If you can't create folders or add shortcuts to the start page with the Google Android TV launcher, then you probably can't. You need to look into using an alternative launcher or maybe you would find the regular tablet UI Android builds more suitable for your use.

IIRC: If I Read Correctly or If I Remember Correctly ...roughly, I had already guessed... ;-)

where can i get the tablet ui android builds from.
So I can test this times.

...how can I uninstall the OpenGapps if necessary?
do I have to go into recovery mode to uninstall?

You can find all my builds at

You can't directly remote gapps as they are added to the system partition. One option is to remove the gapps backuptool script (in /system/addon.d/) or just wiping the entire system partition in TWRP and reflashing an OTA package (edit. I haven't released any OTA packages for LineageOS 18 builds). I'd just recommend starting from clean installation in this case.

Hi Konsta,

I tried u r "lineage-18.1-20220121-UNOFFICIAL-KonstaKANG-rpi4-atv.img" image on my new pi4B 4GB model, but it throws below error.

start4x.elf: is not compatible
This board requires newer software


But I recently updated the pi4 firmware to 10-4-2022, not sure why its giving this error.
When i try installing "lineage-19.1-20220407-UNOFFICIAL-KonstaKANG-rpi4-atv.zip" it works, but the reason i m trying for Android 11 version is there is no working Gapps for Android 12!,

Can you please help me to fix this, I am trying to make my pi4 same as android TV's UI where i can get Netflix, Prime,Youtube.... with all USB playback options. please let me know which is the best way to do.

Hi Konsta,

Thanks for the link, got it working. :)

I would be looking forward for future releases including android 12 TV with Gapps working.

You can copy hwcomposer.drm.so (one in both /vendor/lib64/hw/ and /vendor/lib/hw/) from the latest LineageOS 19 build.

Dual-HDMI doesn't work with KMS driver in 5.4 kernel but headless mode works fine.
Hi KonstaT,
i tried replacing both hwcomposer.drm.so files in your lineage-18.1-20220121 build with the files from the lineage-19.1-20220407 build to make headless mode work, but it still requires a hdmi display to be plugged in for booting. The apps i want to use do not work with your latest 19.1 release.

Could you please provide a link to both hwcomposer.drm.so files that work for headless 18.1? thanks

It boots just fine for me without any display connected.

You need to mount the vendor partition writable to make any changes (or mount the sdcard on your Linux computer and copy the files over).

Hello Konsta,
had to take a few days off due to health reasons... ;-) ...but everything is fine now!

If I set up the A11 again and don't install OpenGapps, how do I get an alternative AppStore like Aurora or F-Droid... I downloaded these as apk, but in recovery mode I can only install zip files. Is there another way to install apk files without installing OpenGapps?
possibly a guide or a link to a guide?
I wish you a nice rest of the day...

E.g. copy an .apk to an USB drive -> plug the drive to your Pi -> use built-in file manager to browse the USB drive -> double click on an .apk to install.

Or dowload .apk to your computer -> connect to your Pi from your computer using ADB -> execute 'adb install appname.apk' on your computer.

OpenGApps builds are automated untested builds and they tend to get broken sometimes. Correct place to report issues with gapps with appropriate logs would be e.g. https://github.com/opengapps/opengapps/issues/873 where we've discussed similar issues on several occasions before.

You can try using an older OpenGApps release.

Im having trouble getting HDMI-CEC to work. TV is a LG UH6100. CEC works fine when using libreelec on the same pi and hdmi ports. Where do i start to debbug the problem? It is possible that my TV have some type of old CEC technology, it is called "simplink" on TV options, but im not sure simplink is the problem.

I tried to use this ROM to run my pi 400 as a media platform. Apple TV refused to play any videos, with the usual lack of messaging. It's likely some DRM not being present or supported.

When using Paramount Plus, videos play, but it's pretty choppy and buffers a lot. Haven't tried downloaded video yet. Maybe it needs hardware acceleration?

Can't try the other atv build because there isn't. An atv (or any other) Android 12 gapps package.

Impossible to say without seeing any logs. Logcat?

Generally speaking H.264/VP8/VP9 videos at 1080p should play just fine using software decoder. It depends on the app/service which codec it uses for video streaming.

Attaching the 2 logcats on paramount plus. And also attaching the logcat on AppleTV.

    Here’s my build of LineageOS 18.1 for Raspberry Pi 4 Model B, Pi 400, and Compute Module 4. It is unofficial and unsupported by the LineageOS team. It’s for advanced users only. Pi 4 model with at least 2GB of RAM is required to run this build.
