Device certification lost

[krishbarnwal]

I unlocked the bootloader of my device Galaxy M01 and then relocked it. I did'nt flash anything. But even after that my device certification was'nt restored and is still at 'Device Not Cerified'. Is there a way I can gain back device certification?

Try resetting your device. If not, you can try this
g.co/AndroidDeviceRegistration

I did that did'nt revert at all. Is there any other method.

DUE TO BOOTLOADER UNLOCK RELOCK MAY THAT IS CREATE ISSUE

IF YOU FLASH WITH ROM AND IT'S AGAIN GETS INSTALLED FIRMWARE IT CAN BACK THAT CERTIFICATION

TRY AS YOU HAVE ALREADY RESET
LAST TRY THIS
