hello friend
as start i apologize for my bad english

i have encountered this problem before on my G935FD , and it's really big **** .

- first , you can't flash or make any repair process because of frp block protection .
- second , your DM problem make your device unbootable so you stuck in recovery mode with some redlines about dm fail .

after 10 days working on it , guess what ? i finally solve the problem and i'll help you right now

so here's this simple and spectacular solution :

1 - flash your device with official firmware .
2 - after flashing you have to connect your device into download mode again and give it FRP/EE Reset with any supported dongles . for me i've used BST " this is the most important step " .
3 - while flashing FRP File you'll see " custom binary blocked by frp " don't worry it's ok .
4 - restart your device into recovery mode .
5 - use volume keys and select " reboot to bootloader "
6 - congratulations now your device booted up again .
7 - after booting up your device will ask you about owner gmail accout as usually , just write it or bypass it via accepted ways .
8 - after finish your installation go to settinges . enable developer options , disable OEM Unlock .
9 - now you able to flash any custom recovery , just flash TWRP and root your device . " this is important to fixing DM files in your device "

after root , the problem solved and your DM have been fixed
