You are not even read my question and you answer . If you are of this thread ok bye bye .
READ FIRST THEN ANSWER .
I've read through twice now, and NO the answer to this problem is not already mentioned.
*#3954391# is not required after you unlock with the authtokendecrypt...
Edit:
I'm not on February patch and it is possible it no longer works, I'll post back once I update to the newest version.
Tbh just stay on Europe EUEX Dual-SIM and don't change from that region, I don't understand why you'd want to pick anything else. The Theme store is doo doo, call recording isn't even that useful and once we unlock the bootloader and can modify the stock rom you can enable it anyways.

So now that you have read first you can leave .
Maybe we are already in another region and want to turn back to EUEX??

Try disable every other network adapter, if that not work if you have laptop this finally works to me:
1. Instal msloop
2. Uninstall every other network adaptor except network Wi-Fi adaptor (and ofcourse msloop)
3. Disable Wi-Fi network adaptor.
4. Configure network address box on msloop.
5. Reenable the wireless adaptor.

@ladylover USB debugging enabled? Is your phone recognized in Device Manager?
This worked for me as well, so thank you for posting this precise combination of steps :cool:.

I had tried every other sequence of disabling adapters, installing loopback, etc, but none of them worked. However, your steps finally resulted in OK displaying, and then the remaining steps worked exactly as described.

I just updated my phone to Australian EX and the Android 11 update was available immediately after reboot.

Thanks for the guide.
