Redmi 4 prime doesnt start anymore after locking bootloader in fastboot

[foggy73]

hi all
i am quite desprate because my 4 Prime doesnt start anymore after locking the bootloader in fastboot for security reason (e-banking). the problem now is that the devices doesnt start anymore. holding the power bottom to restart the mi logo appears just a second and the device shuts down again.
was on android 10 havoc and everything worked fine.

tried to flash via miflash but then got the error message Flash tz error.
can just boot into just fastboot but not able to flash a recovery or oem unlock.

does anybody have any idea to make my device working again?

thanks in advance.


hi all
finally found the solution on youtube: open backcover, disconnect battery, build bridge for the two ebl points, open miflash where phone was recognized on com port, start flashing flash version of global rom.
.... and so i am back on Android 10/Q for loved 4 prime.
best seaon's greetings

I had a similar problem on my redmi 4x years ago and the problem was that I didn't have the correct drivers installed so miflash didn't detect the smartphone as a a COM port and didn't let me flash anything.
