Hi, i have a xperia z2 totally unresponsive, no power button, no volume buttons, no red reset button, no power on any form but magnetic port, no testpoint function (testpoint connected to ground or plates or point near to upper screw or any other know ground point).
The whole thing started when i try to flash some custom Unofficial LineageOS 16 for Sirius board!
I try to update TWRP from 3.0.2 to 3.3.1 and flash the rom with gapps for android 10. The rom in TWRP mode shows an error and stop flashing, then i try again with wipes and same error, i try gapps and same error, then i reboot to system and crash, good bye BOOT, SYSTEM and all.
No PC response too. It just power by putting into magnetic dock, just then the phone power on and stuck into SONY logo.
There is a form to get the phone back to life??
