I'm not responsible for any damage to your device of any sort.
By flashing this you take responsibility of anything that happens.
Process at your own risk!


If you want to check firmware - please make backup. Better to store all partitions, at least efs and may be modem.

Instructions
1. Install twrp
2. Download the zip(s) - firmware and Google Apps additional package (optional)
3. Backup all partitions (it least efs) and store somewhere - it need to do - because you can loose imei
4. Full wipe all
5. Flash firmware and gapps

Work
almost all

Uh nice - thanks Valera! Any chance you can add your manifest? I would like to try building Android once myself.

Error flashed on screen on reboot
I am getting 'There's an internal problem with your device. Contact your manufacturer for detail.' error on every reboot. I've flashed the 'BL_T825XXU3CSH9_CL16530048_QB25611745_REV00_user_ low_ship_MULTI_CERT.tar.md5' bootloader but still facing the issue.
See the screenshot for error message.

Hi there,

do you have any intention to include palm rejection on Q?
It's the only missing feature on LOS...

Do custom ROMs have to have palm rejection added? It's not normal feature?

This would be good to know as I got this device to use the pen!

I notice that screen is very hard to wake up. I have to play all buttons in random combination to be able to bring up lock screen. Once it get unlocked, everything works find.

I did once get system UI locked error. I have to push all buttons to force it reboot.

So I tested this rom on my T820 Wifi and in my opinion it works pretty stable, except of some issues I recognised:

- Saving pictures does not work. The pictures I get are scrambled.
- sd cards in ntfs format not working
- Palm rejection is not working
- ed xposed causes boot into download mode
- screen wakup is sometimes slow
- Viper4Android is not working
- Speaker only working on one site (right)
- it's not possible to rename SD Card or uninstall any system app like mail-app via root
- Netflix is not working
- Not possible to activate a custom notification sound
- Adaway only working with systemless host activated in magisk
- trying to use miracast causes a complete crash of system ui and makes a reboot necessary
- digital wellbeing randomly fc if settings menu is open
- sometimes hardware buttons stuck and i have to wait 5 sec until I can use them again

Thanks for your work!

*update: On second build same issues and camera just force close, now

did anyone figure out how to get the camera to work. It takes pictures but to view them they all look scribble.

Just try it. I think the specifications are the same like T825.
