You can't just... solder the chip from one phone to another... Lol..

Nexus 4 has LTE, but no LTE amplifier, so it's working only on places with very strong signal with low noise. Quite useless and your idea is really nonsense.
I'm not saying it would be "easy" to do just wondering if it would be possible. I also already have a Nexus 4 (otherwise I wouldn't even ask this) and even without the LTE amplifier the signal where I live is still great all the time. I've never lost the LTE connection.

Well I just don't understand. MI2 doesnt have LTE. It can't be enabled by firmware as Nexus 4 could.
And soldering chips is a nonsense. Better is just to buy LTE device like e.g S4 Mini LTE.

The S4 mini specs are quite terrible compared to the mi2s and it costs more! I would have got the s4 mini if it had the same specs as the full size s4.

Dude, even if you had the skills (i'm not saying you don't have) you'll need:
1. Physical place on the motherboard to place the LTE modem/ Replace the existing modem with one that supports LTE.
2. Software skills to develop the kernel that will support LTE and the drivers to the modem.
3. I guess you'll also need to make hardware modification to the motherboard....

Bottom line, if you are not some genius engineer working in Intel or some and have LOTS of spare time, it's a dead case.
Time=Money and the time, money and effort you'll put to it worth buying 2 Xperia Z1.

Best regards.....

Software wise it is all written already for the nexus 4. The motherboard wouldnt need modification either as far I can tell as the two chips are identical other then one being lte capable. I have been trying to find an alternative phone but none have the same compact size as the mi2

In theory he just has to use Nexus4 modem and RIL libs.
Exactly.
Yes, but still lot of work is needed to use on your phone. Or you are expecting "copy - paste" implemenation?

P.S.: http://en.wikipedia.org/wiki/Sony_Xperia_Z1_Compact . Same dimensions, LTE ready.
I have taken a look at the Z1 Compact and it is a nice phone. Not quite as nice as the Mi2s though. The screen is the same size but the Z1 compact has a much bigger bezel making it a bit larger then the mi2s. Not only that but instead of touch buttons along the bottom they are part of the screen giving you actually less screen space most of the time. Not only that but it is also $600 compared to $300 (mi2s).

hardware wise, there should be no problem switching between these chips and that's based on the fact they are the same as you said. Just a "module" added. Now how to implement ?Unsolder ,replace, solder: is it feasible ? these soc are damn small.
