Hi, I have serious problem with my phone, Redmi Note 3 Pro. I had xiaomi.eu rom that I installed on locked bootloader. Lately I wanted to upgrade my rom, asked for unlocking and I receive SMS withing few days. I installed china dev rom 6.3.24, unlock the bootloader (3 green signs and button to reboot). But now I have problem with installing TWRP. I mean I don't have problem, because it's installed correctly via fastboot, but when I reboot and tries to enter TWRP, on the screen of my phone I see black screen with image of my tlephone with USB cable. People are saying it's because my bootloader is not unlocked, but I tried to unlock again, but unlocking failed at 50% with information: no unlock needed. Can someone suggest me some solutions I can try? Or maybe point me into tutorial, that will make possible installing xiaomi.eu rom without unlockig/TWRP.
