Not working over all, but things are a bit different

clean install get a bit further, to my data.… but that is also a bootloop then!

dirty installs over LOS 18 & 19, will boot even further and get to the home screen for 1-2 seconds, but then it crashes and goes into rebooting. Can’t get logs, unfortunately.

Maybe a MINIMAL build would be worthwhile!?

LOS 19 runs very stable and has no boot issues:
lineage-19.1-20231112-UNOFFICIAL-gt510wifi.zip

I made a new custom build with fewer apps…

Unfortunately it is exactly like before.
So, your changes did not make difference.

Boah, this device is a real challenge… can anyone help?

Have you ever come across some documentation on what the boot order is on /e ?
And for LOS, in oder to compare them? Or some emulater with debuting features maybe?

There are patches for audio and camera which I could not apply. I cannot build when I apply them. might be the reason but might not

Yeah, is the entire stack required at the beginning of the /e-setup already, or are things still loaded in the background… camera is used for WiFi qr code scanning… but then again, I had LOS 18 installing on a Sony with two broken cameras – that’s why knowing the boot-oder would help, I think.

Bootlogs would surely help if anyone can provide…

Ok. Another try with the R build. I think I did apply the patches now correctly. Worth a try:

Is there any change to have a version e-2.2-r for this device?
It would be very appreciated! Thx!

Final update for /e/OS 2.2 (hope I applied the patches correct):

I’ll respond here, once i’ve the device available

@ronnz98 thank’s for your work.
It would be cool if the tablet could be officially suported one day.

I have tested the build e-2.2-r-20240722-UNOFFICIAL-gt510wifi, but don’t work for me. While your build e-2.0-r-20240518-UNOFFICIAL-gt510wifi works.
I don’t know what happen, the initial start-up never finish.

Some remark about my test of e-2.0 :

  • I was not able to disable the button bar, since the tablet as physical button, the virtual one are not needed, and take space on the screen when displayed.
  • even if I setup for an azerty keyboard in preference, virtual keyboard display a qwerty one.

Thanks for the feedback!
The device is not easy to build and need a lot of patches. Potentially I did not apply all of the patches correctly now on R-2.2

Since /e/OS-R reached end of live unfortunately this will be maybe my last build for this device unless there are new sources and developers working on newer Android versions

Update for /e/OS-R 2.3, do this version work?
