Hello all, please help me. I have a P20 Pro Chinese variant CLT-AL00 and i was bricked 3 years ago and i decided to unbrick. Then i removed back cover for testpointing and it worked! But i have some problems about flashing. IDT can't see my device even i installed proper drivers, tried old and new versions but nope, isn't working. I found 2 board softwares from androidhost.ru but IDT says ''the file is invalid''. What can i do? Please help me
