How did ur phone hang on logo, what did you do?

Remove and re insert battery

@eddiecen
you wiped security areas
flash same partitions and check
you can use Inferno Partition Manager to write each partition (use it carefully)

a71 without data loss unlock possible?

sorry for model no mistake y71 without data loss unlock possible?

If phone has android version 8.0 and above then unlock not possible without data loss.
