    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!

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

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