So, this is the case: I have a Redmi Note 3 MTK 3/32 gb. ROM is MIUI Global 7.2 / Stable 126.96.36.199.0 (LHNCNDA), is an old ROM. Bootloader is locked. I cannot flash the latest fastboot China dev rom, because BL is locked. I cannot unlock with Mi Unlock Tool, because I have to bound device with Mi account. To do so I must go in developers options > Mi unlock states. This Mi unlock states is just not there, I think because of the old MIUI ROM. So, I cannot bound device to Mi account. I put device in Mi account with logging in in Mi account and the device is there, but seems not to be bound like it should. So, I am stuck here. No bounding no unlocking, no unlocking no flashing and no TWRP. Anyone has a solution to unlock?
