3G Network Issue

[Volkv]

Hello. I got network issue yeasterday just after I replaced my sim card with another one. No H and H+ work, only crapy 3G (UMTS). Nothing helps - wipes, another roms, radio flashing... I begin to think that its a hardware problem, hope its not.How may I fix it? Where can I find help? In russian forums I founded 2 guys with same issues.

Thanks for any help.

What radio did you flash and also where to find any? I'm losing mobile network randomly, I have tried several roms and it's the same, perhaps radio flash would change something for my Mi2

Thanks!

Thanks! I'll try this out.
Netherlands, KPN and even though my connectivity issue seems different from yours I had this since I got the phone, few days ago I hope to find a solution.

EDIT//
Unfortunately no difference with the radio flash.

Have you opened *#*#4636#*#* menu and choose LTE mode before that? Or just after flashing 3.3.1?

Before that I did not know about this menu! Just flash 3.3.1 dev., Before that I was on 3.2.22

Colleagues from the Russian forum have the same problems as me!

Just found out that switching to performance mode (instead to normal) activated the h+ again!
