In phone, you got version 10.0.0.194 and you try to write to phone 9.1.0.317

Ok

- I connect Testpoint
- Then temporary unlock bootloader
- Device reboots to Fastboot mode after bootloader unlock
- I load firmware files and click Update in Fastboot mode
- Program writes Rescue recovery partition to phone in Fastboot mode
- The program is then supposed to reboot the phone into UPGRADE MODE to write the full firmware

- Phone does not go into UPGRADE MODE even with key press


Phone is dead

Do you select correct firmware files as specified above? Ones in your screenshot are too low version. You need to use standard not advanced method. and preload/cust firmware files are of different version than the one selected on top field?

Go to directory of HCU, in bootloader folder delete existing files, restart HCU, try again, make sure you have stable internet connection, otherwise files may get corrupted, antivirus or firewall may be a problem as well.

BOOTLOADER UNLOCK

Will flashing board firmware help?

If yes, which file?
