sm-g925f DRM error - GSM-Forum

Alva · 07-31-2015, 15:47

I had 5.1.1 and installed engeneer boot to flash custom TPRW and root
After this I tried to flash stock rom and after flashing 5 files rom I get bootloop and drm error in the recovery
How can I fix it?
Besides I get reactivation lock that cannot be turned off

Sorry, I meant Device Root Key error

You must flash the ORIGINAL efs back. Flash the engineering firmware, root the phone, repair the IMEI, unlock, and flash 5.1.1 back. The DRK will be restored when you load the stock efs back.

This is why the EFS shouldn't be wiped through download mode.

restored original efs, then flashed the stoch rom again and its ok. Thank you
