I have a N770F phone (ex N770X, repaired IMEI and patched certs so KNOX is 0x1). It has regional lock to MDL region. Is it possible to unlock it via Z3X? I tried to read codes, but it requires KNOX 0x0.
Phones locked by 'T-Mobile'(TMB, TMK), 'Verizon'(VZW), 'Sprint'(SPR)
are not supported for unlocking!

Unlocking using sever:
1. Power on the phone.
2. Tap 7 times on 'Build number' in 'Settings'-'About phone'-'Software information'
to enable 'Developer options',
go to 'Settings'-'Developer options' and enable 'USB debugging'.
3. Connect the phone to PC with USB cable, install drivers if needed.
4. Select device in ADB settings.
5. Press 'Unlock via server DIAG Oct 2019' button, write your login and password in window if it will appear.
(Login and password will be saved as default after first input and can be changed in settings.)

Try to enter 00000000 or 12345678. If this codes not accepter - use ROOT read codes method.

I already tried these codes, it didn't work.

There is no "ROOT read codes" - there is only ROOT UNLOCK, and it doesn't work too (it only removed my cert patch)
Did it (ROOT UNLOCK) 2 times and it worked. Thanks!

I also tried "Unlock via Server [ROOT]", but the only thing it did is removed my patch cert so i had to patch certs again.
