Can i unlock with fake roms in my phone??
I have miui 8.0.5.0.0(MBECNDG)

I dont know but if you have installed non original rom isnt ur phone already unlocked?

Probably you can unlock your phone just make an application you can probably check the bootloader state from fastboot by
Code:
fastboot oem device-info
in fastboot mode

Hi
I have recently purchased a Redmi 4 Prime phone that came with the vendor rom and I wanted to flash the latest china dev rom, but am stuck in bootloop. cant enter DL mode, but fastboot is OK. unfortunately none of the adb commads work, the phone is recognized under "fastboot devices" but not under "adb devices". I have tried the fastboot2edl v2 method but is goes straight into bootloop. can you please suggest what to do and help me out?

Try to turn it off and press volume down + up and power until the LED flashes red and connect USB - it should be recognized as Qualcomm ******

If not, then build your own deep flash cable or order one on ebay or something... - with that u can reach the DL mode on nearly every Qualcomm device

usually the issue with unlock is a different username used to login. use the same, either email, number or name on both.

should solve it.

Then use unofficial unlock.
I can't because unnofficial roms need official unlock...

well did u synced with mi cloud and enabled find then watched if its available in i.mi.com?

Yes i have it synced... I think that my fault was the reason of the applying... I wrote a copy paste one...
The thing is that i have to wait for the next month or i have to make another account?! :crying:

    Then why you say in the unnofficial way this "Warning do not flash xiaomi.eu global or any other unofficial rom this way !".
    It's something new what you say?

    Yes, 4pda patched bootloader appeared after fastboot oem unlock-go solution.
