Unlock BL and root on C6606

[spc_hicks09]

Youll have LTE. Everyone told me I would not but I always did. I always had to go into settings and download the data settings.

I'll check it out again later then. So you're on T-Mobile too?

As far as I know there is no custom ROM for a different variant (C6603, C6602), that would run on the C6606 and would have working WiFi Calling. Unfortunately I think we're all out of luck.

Yes, you can. I have done!

I know there are 100 different threads on both of these subjects but they are out of date, cluttered, and unorganized. So my question is, can I unlock the bootloader on this thing and root it, or not? Here's some info:

Model: C6606
Carrier: T-Mobile
Android Version: 4.3
Build Number: 10.4.C.0.814

Any help is greatly appreciated.

WIFI calling function will not work ofcourse but if you are not satisfied you can flash stock firmware anyday using XPERIA FLASH TOOL. You need to unlock the bootloader using official Sony Method. If you can unlock the BL which I was able to.
Then you can download and install Cyanogenmod 13,12,11,10. (C6603) - Yes, it has issues, so I switched to.
SlimKat 4.4.4 - YUGA (C6606) - NO BUGS AT ALL.

Also do remember to flash SGAPPS from their repository no the opengapp.org gapps.

Big difference I found is that Stock OS on new flash takes around 500-700MBs of RAM where SlimKAT takes only 350MB w/o GAPPS and 500MBs GAPPS.
