Lollipop and cross chipset porting

I am trying to understand more about android to be able to get MIUI running on my bullhead device.

How is google stopping us from running Lollipop on it and can it be bypassed?

Is it possible to port a for example SD 810 rom to our SD 808? I understand it might not be the easiest but I can't find any information at all about cross chipset porting, only for MTK chipsets.

I know that this is probably not any easy task and it would probably just be easier to buy a MI device, but I got nothing to do on my vacation so thought I would try and educate myself some.

Cross Carrier HD/VoLTE Rollout

Gentleman, Cross carrier HD Voice / VOLTE appears to finally be a real thing.

A few minutes ago I had my first HD VOLTE call with my mother. I'm Verizon/N6p, She's ATT/Iphone6. We're both in Brevard County Florida

A quick googlin' shows they are rolling this out in select markets.

Anyone else seeing this with other carriers or other areas?
