Hi, I would appreciate someone helping me. I have a redmi 4x with official global rom 9.6.4.0. I can not unblock the bootloader. officially xq I always get error 60091 and I do not get permission. Is there any way to unblock the bootloader unofficially? Or can you install twrp with unlocked bootloader? I just want to install a rom xiaomi.eu. thanks and regards
