Can't upgrade to Android 4.2.2

I had successfully upgraded to Android 4.2.2 using PC Companion. I decided to install CM10.1. So I backed up my TA Partition, unlocked the bootloader and installed CM10.1. It was running fine but I noticed that my phone cannot connect to my network. Baseband is shown as unknown and there is no IMEI. So I reverted back to .307 TW version and relocked the bootloader. Now when I upgrade to 4.2.2 version, my phone boots and after few seconds it tells me that system has stopped responding and if I want to wait or reboot the system. No matter what I select my phone reboots. This keeps on happening. I've now reverted back to .307 version. Please help!!!!

Do a repair with Update Service, that nearly always fixes things

It happened to me as well, SUS won't help. Follow this steps and u shud get ur dead device back to life.
1. Flash .307 TW ftf (wipe everything) (Indian ftf recommended for u)
2. Root it using Doom's tool kit (connect it to flashtool to get device busybox n bla bla)
3. Download ta partition tool v8.0 (this version worked for me, i tried all from v9.3 to v8.0) (Ver 8.0 asks for IMEI no. used to unlock, keep ur IMEI no. (15 digits) handy
4. If ta restore is successful and still u don't get ur baseband back, do this: Flash .307 EXCLUDE PARTITION
5. Reboot and u shud get ur IMEI, Baseband and ur XZ back
try it...
PM me if u need any help.
Good Luck!

It didn't in my case. I upgraded my phone from .434 (Indian) to .423 using PC Companion. The phone reboots every time.

Just to be sure, please give Update Service a try:

It's a lot more robust than PC Companion.

Yes right, or else just flash with flashtool...

[Q] 4.4.4 update failed

Hello. I just tried to update downloading via wifi. It downloads successfully, but later on restart and attempt to install this update, process fails and phone restarts back to previous 4.4.2. http://i.imgur.com/GoJrjqu.png
Phone is not rooted, I have never done anything to it what could cause this, just regular updates.
Message says "Could not install new software version. Try again." - http://i.imgur.com/3terGra.jpg
Have anybody had this issue, contacted Sony support or something?

Guess you are on VZW.
Just download the 6603 FTF
Exclude baseband while flashing the FTF from flashtool and you should be set.

I do not want unlock bootloader and root it just because an official update won't install. :/

Problem with Wifi and BT after update

Hi,
I updated my Moto X to version 4.4.4 and then not work wifi and BT. I tried to reinstall via RSD, I installed a rom, back to 4.4.2, change the files in the folder / persist and still does not work ... If I go to MAC address says "Unavailable". Any solutions? Not to do, unlock the bootloader and therefore, will not have warranty.
Thanks!

Please help me

I have TWRP installed on my unlocked phone so I would do a complete wipe of Dalvik, cache and system and then use the moto x toolkit sideload option to reinstall 4.4.4.
I don't know if you can do this with a locked phone.....

U can easily take kernel only from an ftf bro. Like i said download one ftf and flash it via flashtool. While flashing exclude all except Kernel.sin and FOTAKernel.sin. Done..

dude, my phone got this issue too, if you've solved this, can you share it to me dude? because i am stuck with bootloop issue to when flashing stock fw!
