Thats very cool!
evaluating this built, this is what I did to install,
1 boot to Fast boot.
2 fastboot boot twrp_3.7.0-12-spes-2023.08.21.img
3 adb sideload e-2.4-u-20241105-CUSTOM-spes.zip
4 reboot to recovery
5 factory reset
6 reboot to system
7 keyboard is missing - install AnySoftKeyboard (transfer apk from laptop)
What works?
Bluetooth audio
internet
fingerprint is working
Batterylife is good
GPS is working
~ install my favorite launcher
Trust - signed with public key
long press for flashlight, causes unable to shutdown/restart the phone.
If there is more, I will let you know.
Thanks a lot for this initial build.
