Hi there I was trying to Unlock this device J727az with GCPro I made this operation:

------------------------------------------------------------------------

Searching phone...
Device Found..
MODEL=SM-J727AZ;UN=C00003AA7D862B4;CAPA=32;VENDOR=TOSHIBA;F WVER=3;PRODUCT=500073;
Init ok..
Device := SM-J727AZ:USA:AIO:1:J727AZTUS3ARF1
Samsung Exynos EFS Reset Success..
Fail-Flash..
Possible New BootLoader Try Downgrade and retry...
Finish...

!!! Success !!!!
Restart Phone if not auto...
Total Time Take...00:03:23

------------------------------------------------------------------------------
I made a Backup of the imei's Certificade before this operation.
After this, the GCPro GUI was frozen, the device was at dowload mode stucked at half line of progress. I reset my device and its stucked at a boot loop at Cricket's logo. I re-flashed full firmware, and tried with Combination firmware too, but my device never finish booting up.

Any idea how can I fix this problem?
Ive never face this problem before

If I enter to recovery mode and try a "Factory data Reset" I get this error:

<

Suported API: 3
E:failed to mount /efs (invalid argument)
E:failed to mount /efs (invalid argument)
E:failed to mount /efs (invalid argument)
dm-verity error...
