Hello.

Try to write different Cert files from the Support Area. IMEI of Cert file, which You've used might be in "black" list of Network provider.
Also, try to find and select Network manually.

I tried many different Cert, same problem. I always check IMEI of Cert before writing.

Make Factory Reset, reflash the phone, then try to find and select Network manually.

Got it. Everything works now. It looks like some certs, even though went through and is not blacklisted, do not work as good as others. Thanks!!
