Repair modem first but don't upgrade phone firmware until all operations complete, that is, get version 6.0.1 with same binary:
Code:
PDA version: G920FXXU5DQA7
CSC version: G920FDBT5DQA3
After, read phone to check if modem is ok like:
Code:
Phone version: G920FXXU5DPL3
Then do all the efs, nv, cert operations!

Also, your problem may be related to the damaged modem! after you repair modem you probably recover original imei! verify that!

DRK is an operation you do to repair a certain condition of phone, not a file to be shared!
If your phone does an error on recovery mode with the info:
Code:
dm-verity verification failed need to check DRK
Then you need to do the DRK repair using UART cable with box!

From your log, the firmware installed in your phone is from germany dbt so, you do a search for G920FXXU5DQA7 on s.ammobile and you'll see many firmware from various regions. Just get the Germany DBT one:

https://www.sXammobile.com/firmwares...U5DQA7/122610/ (remove X from sam)

Flash it to see if you get modem repaired! You can flash only the modem, instead of all the fw so you save 1 minute or 2.
