The tmobile variant has a locked bootloader so youre limited to lb roms. And no custom kernels

I've had similar issues and after a phone hard bricked randomly after a reboot I just run stock rooted now. I would love to be confident in custom ROMs on this device as I am with my Asus Transformer.

If anyone has any suggestions it would help. Do we need to flash rooms in sequence to the version we want? Do we need to change our version to a 6603?

I'm in the same boat. Spent the better part of last night flashing and recovering from bootloops over and over. I am okay with the stock rooted ROM, but at this point my battery life sucks and it is bloatware that is causing the brunt of it. I would love me some stock Android.

Just make sure that you have followed instructions exactly. Make sure you flash whatever kernel is listed with flashtools after flashing the ROM.

Been rooted/custom stock ROM since day 1 with my t-mobile C6606 and haven't experienced any problems.

Best bet is to start from scratch by flashing a complete generic 4.2 ROM with flashtool, root/recover, and then upgrade to pre-rooted ROM.

Sure you are aware, but you will lose the t-mobile specific functions (wifi calling), but also the bloat if you move to a custom stock ROM like eXistenZ.

Do you have a suggested generic 4.2 ROM in mind or just look for an unbranded 6603 4.2 ROM .ftf and flash with flashtool? Then root, install XZR and follow directions for what ever desired stock based ROM such as .101, correct?

And Im assuming, do not flash the baseband for the 6603 or other non 6606 device, correct?

Flash custom stock ROM of your choice. There may be an easier way than this, but this is the route I have taken and all has worked well.

T-mobile APN's for 3G/4G/LTE. I input these every time I clean flash. I confirmed these settings with a friends moto x that is completely stock » http://xdaforums.com/showthread.php?t=2236735 4G will actually show as H+ by the signal bars.

If you run into any problems let me know and I'll try to help. Just take your time and follow all instructions. It's well worth it rather than waiting on t-mobile to push our updates, especially now that KK has been officially announced for Q2 (hopefully May). T-mobile will probably be another 2-3 months behind that.

TMo will probably be further behind than that as we don't even have an official 4.3 yet.

Thanks for the instructions. That's exactly what I have been looking for. I'll give that a shot asap, when I get the courage to flash the phone. Probably the next day our two.

Yeah I tried doing this method and now I'm stuck in the boot loop at the sony logo screen. Still not giving up though, am I suppose to flash Update to .101 after or before installation of the rom. I installed the rom prior and now my phone is stuck in bootloop.. I tried using Sony recovery and flash tool to get it back, but it wont recognize my phone and if it does its for a second. I can get it in fastboot mode and CWM and that's it..now I'm stuck AGAIN atm..

Somehow I was able to get and keep it in flashmode and flash the whole firmware C6603_10.3.1.A.2.67_Generic UK. Looks like I'm back from start one! :) So again, am I suppose to flash .101 before or after the rom is installed?

To be on the safe side make sure you install everything in the order that I posted them following instructions. Work your way to the .101 pre-rooted ROM.

When you get to the .101 ROM
flash .zip provided in recovery
Do not reboot after flashing .zip, in twrp go to power off
Then flash everything in the .ftf with flashtool
Reboot and you should be good.

Also make sure you have the latest flashtool and drivers loaded. Never hurts to check the obvious too like USB debugging..

What steps in the process would I have to omit if I dont want to root and just want to flash 4.3, Also there seems to be many versions of 4.3 such as UK unbranded Ch unbranded. If I'm using it for Tmobile US, which would I choose?

Hey man yeah everything seems to be perfect except for the MMS aspect of my messages. I can't seem to download the MMS messages, the default texting app keeps telling me that "Could not download message. Check settings for multimedia messages and try again later" I tried the APN settings to the forum you directed us too but that's not working =(

Make sure the APN you created is selected and then reboot after.

Make sure LTE (preferred) is selected.

Once verified APN is selected and reboot, go to MMS and long press picture, select download. It should DL after that.

If that doesn't work you can also try to "Service Providers" and there should be an option for a T-Mobile network.

Can also try turning on/off airplane mode, but the APN always works for me.
