Oopsie, I didn't catch sensors error while bringing up U QPR3, resulted in this build has broken sensors...

Since we've switched to EROFS, making hotfixes isn't longer possible

I'll rebuild it with the fix later

Failing to record screen on latest LineageOS 21? Disable the "HEVC encoding" option. This option shouldn't had came to our devices...

Kernel 4.19:

Android 14 QPR3:

- Other small adaptions

If Google would keep on doing the same shit in every QPR updates of Android 15, our devices could only survive till Android 15 QPR2 I guess? maybe on Android 15 QPR3, even if we managed to boot it, some hardware functions would stop working

actually, having k5.4 won't make it survive for much longer (old HAL versions is a blocker too), I'm doing it mainly just for the sake of "the first k5.x for our devices" and "the 3rd kernel update for our devices"

one step further
