If you you unlock your Z2 pro you get a special bootloader. Afterwards you are not able to do any OTA updates. The update program downloads the corresponding update but it is impossible to install it.
TWRP gives an error and if you flash the original recovery it also gives an error. Does anyone have an idea how to update the device if it is unlocked?
As you have to flash the patch bootloader for TWRP it is not possible to have the original bootloader back.
So how can you Update and how can you recover the original state of the device?
The SDFUSE method doesn't work either. Flashes without errors but after reboot everything is untouched.
