first of all download this for full files you gonna need
https://mega.nz/#!Koh3kaYT!bt3pJ0shvDjhoXgw9mk-NSLtIrDswdaIfUXkfrKzsd8

client giveme and G925F with DRK FAILED problem, so the phone was stuck on samsung logo, and entering in recovery modem says drk problem showing android 6.0.1 installed ( )
so my first step was download to 5.1.1 with G925F_XXU2COH4_TEF2COH1 (to fix DRK with a friend gcprokey if he can) i put 3 files of this rom (AP, CP, CSC) AND the OLD BOOTLOADER that you gonna find in the packet called " bl_old.tar.md5 "
that gonna make you phone boot again and you cant enter in desktop, etc...
now, the bad news its phone gonna show UNKNOW BASE BAND AND IMEI NULL, you can fix this with propper tools (gcprokey) but if you dont have that continue reading....

ok, lets move on, with the phone working good but with imei null i decide to put again Android 6.0.1 in the phone so i download G925FXXU3DPAD rom and flash, now again phone shows DRK PROBLEM but dont worry we gonna fix that

turn off phone again and put it on download modem and flash "Kernel_G925F_Sforum"... ok the phone now enter again in recovery mode and still showing DRK PROBLEM, but don worry, just select reboot and voila, phone gonna start without problem...

NOW, the phone gonna show correct BASEBAND but with imei 3500000006 (emergency call only)

you gonna try to write new good cert but gonna shows an error

ok now we gonna try to write again new IMEI AND PATCH CERT but WAIT we are on 6.0.1 how come gonna patch cert if its not supported?

dont worry, just go to flash mode again and flash modem "MODEM_G925F_OJ1" ( 5.1.1 modem) if you wonder why that modem its because it match the bit 0J1 with G925FXXU3C"O"J6 6.0.1 modem, so if you downgrade modem you dont gonna have imei null again

now that we have Android 6.0.1 but with modem 5.1.1 we can write new imei and patch cert

after that phone gonna work like a charm with android 6.0.1 and repaired drk problem and imei without using professional tools...

-Download and flash the Combination file through odin
-This will enable adb. Run the command to bypass activation

adb shell content insert --uri content://settings/secure --bind name:s:user_setup_complete --bind value:s:1

- Turn on oem unlocking and reset the phone

Full flash phone with last firmware.
