Hi, I've flash Chinese rom with fastboot on my mipad4.
But now, I have a problem when I restart my device, I can't connect to Xiaomi account I have a message :"couldn't check device security info" and I have a problem with my WiFi that I can't activate.
So, now I can't log in to unlock bootloader and flash a new rom.
What can I do ?
Thank you for all
