Hi ronnz98 - I’m keen to try your latest 3.4 rom. Have you tested? What’s working and what’s not?

5

Not tested but they should work

6

Crashes on YouTube shorts I’m just stick to the R version at this point

Hey Ronnz, just saw your Release of v4 for
gts210ltexx.

Will you provide this latest Version for the gts210vewifi too? Please :folded_hands:

Thanks a lot for your effords. Unfortunately whenever i try to install your rom

e-4.0-t-20260619-UNOFFICIAL-gts210vewifi.zip

using adb sideload i get an error message (corrupted ZIP-file or so)

Could you check on that?

10

I uploaded files again. Can you please check later

11

Sorry but I can not see a new file for gts210vewifi. Where can i find it?

Installing worked with the last provided version but the tablet doesn’t boot afterwards. It gets into a boot-loop showing the e with the bouncing dot for some time before it reboots.

14

e-4.0-t-20260615-UNOFFICIAL-gts210ltexx.zip works on my SM-T815. Adding a Google account via MicroG works as well. Trust complains that the build was signed with public keys.

I dirty flashed from e-3.4-t-20260128-UNOFFICIAL-gts210ltexx.zip.

Update for e-4.0-t-20260628-UNOFFICIAL-gts210ltexx.zip

New kernel used:

17

This one (e-4.0-t-20260628-UNOFFICIAL-gts210ltexx.zip) doesn’t work on my SM-T815. It gets to the pin screen and reboots. I did a twrp backup (with e-4.0-t-20260615-UNOFFICIAL-gts210ltexx.zip on it) before installing, and restoring the backup makes the tablet functional again.

18

yeah idk but my tablet is T815N0 works fine for me this can be caused by a old cache because the kernel is heavily modified then the stock one (has execveat renameat2 and newer morden functions)

19

I dirty-flashed but did erase cache. Maybe I’ll try again with a clean flash and try to restore settings with swift backup. We’ll see if more reports come in. e-4.0-t-20260615-UNOFFICIAL-gts210ltexx.zip works really well thus far.

20

Well okay you can so that if you want to but be careful and I’m still working on the kernel to add ebpf which should allow gts210ltexx to reach android 15
