No SIM, No Wifi after global stable update

[macrostr]

Hi, I bought my device with global stable 8.5 rom with officially unlocked bootloader with replaced imei (Turkey Problems).

Installed miui 9 developer beta without problem (xiaomitool)
Downloaded 9 stable recovery virsion and installed with Setting, system updates, select package...
Device booted but no sim or no wifi network. So I cannot pass mi cloud account validation.
I can flash twrp and all fastboot versions of xiaomi roms.
Xiaomi roms can boot but I can not pass mi cloud step.
RR, mokee roms installed succesfully but they don't boot.
I have QCN file backup but I can not restore it because I can not take phone to diag mode over twrp.
Is this problem related to QCN file, any suggestions ?

You could try with a usb type c to ethernet adapter to pass activation.

Strange Problem you ve got

Mokee and RR will probably work if you format phone by typing yes in twrp after installing the zip
