Have you tried changing the modem? In odin just flash the CP file from other country, then patch again. Good luck!

It has to be modem from android 7.0?

Downgrade to 6.0.1 and try calling if it doesn't work make cert and network repair, if it works and if you still want thr 7.0 update then flash only the ap(system.img).

Good luck

Should I flash 4 file firmware or one?

I tried one file, but error in odin.

Any idea?

You should be flashing with z3x instead of odin because on z3x you can specifically select what to flash like boot or recovery or system. so launch samsung tool pro then on the flash tab select ap then if you have 4 file firmware select ap from wherever it is located then on the right there are three dots, select the dots and untick all of them except system.img then flash.


It doesn't matter whether you have four or one file firmware, if you have one select the file on ap and untick all except system.img.

Hope this helps!
