When i flashed my FP4 with iode i also flashed the avb_custom_key-FP4.bin to relock the bootloader. That all went fine.
Now i have issues with ghost touch on the LCDscreen and Fairphone support ask me to issue this command ##2886## but that dit not work
So i reflashed the original Fairphone ROM to my phone, that also went fine and i could do the test
But now … i can not relock the bootloader anymore, even with the original ROM
When i execute ‘fastboot flashing get_unlock_ability’. It it returns ‘get_unlock_ability: 0’:
How can i restore the FP4 to its original state with official ROM and locked bootloader ?
