You need to ask your network operator what 4G bands they use. Then it will be an easy decision.
I went for the WCDMA version because my network uses 800mhz and Mi4 LTE doesn't support that.

So in update 3, which rom are you running?
Also, have you tried contacting the seller where you bought it from and ask about this issue?

Wow could be a faulty one, I suggest you contact the seller and report it. My Mi4 is going strong after a month of owning, no defects to report.

I think you should check if your Mi4 is fake or not.
I've had my Mi4 for about a month now and haven't experienced any problems like that. Been running MIUI v6 stable for 3 weeks smoothly and perfectly.

Hi mate, sorry but as far as I know that won't work. EFS backup includes IMEI number to my knowledge so if someone gives you their EFS backup it will also contain the IMEI.

Lol its not a bug, it's an incompatibility. So either you change phone or your company changes pin to 4 digits. Those are the only solutions.

MTK is the worst chip in the history or mankind, it's so power hungry and inefficient. It's even worse than the Intel mobile chips.
You want a decent mobile device, buy a phone with a snapdragon SoC.
