SM-G930F: Reading data from phone... error
 

I'm trying to repair my phone with Z3X box, but I'm getting this error when I click on "Repair DRK", and my phone can' be found in download mode. I installed all drivers. Any solution?

You are not using latest version of Z3X, latest version is 30.1

Also try rooting your phone it will fix DRK

It's rooted and I get this now:

Did you tried CF-Auto Root or TWRP? What version are you on 6.0.1 or 7.0?

I used TWRP and I have 6.0.1

Well I recommend you to reflash your phone and use CF-Auto Root (6.0.1)... If you flash your phone with 7.0, I recommend you to use TWRP, but the process is a little bit complicated...

Root for G930F on 7.0 with TWRP: (FRP: OFF)

WARNING: This will wipe your device, backup your data

Put your phone into download mode and run Odin Untick auto-reboot... Flash TWRP Recovery:

twrp-3.2.0-0-herolte.img.tar

After flashing TWRP, boot into recovery.. From wipe select Format Data... type yes and after wipe go back (keep hitting back icon) to Main Menu and select reboot, reboot to recovery..

After reboot browse to install and flash Supersu 2.82 (you can use SD-Card or OTG cable or ADB Push Command):

SuperSU-v2.82-201705271822.zip

Reboot your device... this will take up to 5 minutes

PS: Wipe data is a MUST because when you swipe TWRP it will trigger dm-verity, and if you don't wipe you will be unable to boot

Will I be able to make OTA Updates? For example I want to give my phone to someone who doesn't know anything about flashing and rooting... Will he be able to do updates by him self?

Rooting disables OTA updates...
Same applies DRK repair... it also disables OTA updates...

Does it mean I will never be able to use stock with OTA Updates?
