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: < No Suport SINGLE-SKU 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... > |
