If you use one click repairs, such as Octoplus or Z3X, when it wipes the efs, and clears the serial number, it makes the DRK ng. When it is in that state the phone will no longer be able to take updates, factory reset, or take firmware installation without going into a permanent boot loop. You must repair DRK, or at the least, if your phone is soft bricked use a solution like the one posted so you can use the phone again. You can check in AT terminal with easy code if your dev root key is corrupt or good. AT+DEVROOTK=0,0 if it says ok you're good, if it says ng

i test type AT+DEVROOTK=0,0 it show not found what must i know my devices DRK good or proken please show me coeercet word

G920T DOI1, you will have 7 files. Extract the contents of the firmware to a folder. Then extract the contents of the tool to a separate folder. Don't touch any of the dependency files, including odin that came from the tool. You will only copy four files to the tools folder, those being, sboot.bin, cm.bin, boot.img, and system.img. Once those four files are copied into the cell magicians tool folder, double click the cell magicians.bat, it will take about ten minutes to create a AP.tar and a BL.tar. Afterwards, use oding 10 or above and place the BL.tar in the BL slot and the AP.tar in the AP slot. Place phone in download mode and begin flash, your phone will boot after flash. This does not fix DRK but will allow you to use phone again! The Cell Magicians Tool

Many thanks bro. Revived my phone with your tool.

Found via Google the complete AT cmds...


PHN-P Cert with Private Key (encrypted)




Maybe somebody have more of this...


And also knows how to decrypt the 1200 Byte Private Key?


Thanx in advance.
