Lost Cellular Network and got DRK issue flashing stock rom on SM-910s
The rom was working great for about 5 months and suddenly noticed "Emergency calls only." Tried other simcards and it was the same thing. I tried resetting it by wiping all data but to no effect. Flashed rom again but no change. I flashed stock rom that had worked perfectly months ago, flashed successfully but when auto resetting, I got the error message,
"Device does not have DRK, please install DRK first." I rebooted to stock recovery with the error message,
"Device does not have DRK (Device Root Key), contact to SW PL. Please flash ENG binary then install DRK."
It could not boot into system so I wiped it using stock recovery and got the error message after wiping,
"dm-verify verification failed... Need to check DRK first..."
It still couldn't boot into system so I flashed SuperSU using Odin and it booted into system but again with no Cellular Network.
My guess is my EFS partition is damaged. I installed TWRP and tried to delete files in the EFS partition for the phone to regenerate the files as many do to fix IMEI issues on Samsung phones but still doesn't work for me. And unfortunately for me, I did a silly thing of deleting my original TWRP backup that had efs backup because I've never used them in the past on any Samsung phone I've owned.
I'm stuck with a phone that does show imei and serial so no Cellular Network.
