Hi,
Here is a stock firmware for Xperia TX
I have tried it (it is for Taiwan originally)
Select the firmware and hit download.
If you face difficulties with chinese like me use google chrome

Mobile bravia on never unlocked bootloader

I had 4.1.1 on previously and I flashed 4.2.2 with flash tool and I had problems at first as it wouldn't flash with TA ticked so I backed up TA before installing 4.2.2 just in case it screwed it up.
I tried flashing TA from the firmware package with everything unticked and it still won't flash the file to have chances of getting mobile bravia back
Is it safe to flash the previous one from 4.1.1 TA from the firmware.
Also tried restoring from the TA BACKUP software no luck

Xperia Z was released with 4.1.2..where did 4.1.1 come from?and the only solution to your problem is to just start over.. Download the latest ftf of 4.2.2 and root it with DooMLoRD root toolkit.. Cheers!

Support for 2.245

Hi.
I have got my so rooted and unlocked and have wanted to put a custom ROM on.
But every single one says just support for 2.254 firmware not my 2.245 firmware.
Will it still work or would it brick

Happy flashing

Is that possible as 2.245 is my only available software to update too

2.245
Dear Freind
Roms like pureness 1 and Honamiutreized are strictly firmware specific that is why, i think those developers specifically state do not flash this over other firmware variants that will cause problems and this is because those developers have heavily modded the latest firmware to add more tweaks to give advanced user experience hence that ROM may not be compatible on older firmwares.
But probably you can find Custom Roms (Like Cleaned and Tweaked Rom, JBXSP Rom, Project AOSP Rom) based on 2.245, just go to respective threads and check, you will find that the most of the ROMs' version 2 or 3 should be based on 2.245 firmware.
Try and enjoy customs roms. :laugh:
No if you check this link http://forum.xda-developers.com/showthread.php?t=2311964 you can find many FTF for 2.254 which can be flashed using Flashtool and have latest firmware and flash latest ROMs based on 2.254 without any problem.

Hey buddy,
Don't cross flash .254 FW over .245 FW.
Just use flashtool to flash the .254 FW. It is easy, and there are many guides to do it. Once you know how to use flashtool, your phone also automatically becomes unbrickable as you know how to flash back the stock FW even if you somehow softbricked your phone.
Also, don't post questions in the development section. This is for ROMs and Kernels and stuff, there's no place for questions here. Go to the Q&A section instead next time.
Happy flashing (ROMs and kernels, not anything else )

You will need to have unlocked bootloader first before flashing any CM roms or 4.4.2 roms
To back to original firmware just flash the pre-rooted 4.3 ROM over here
There's many kind.
I prefer you to wait for official 4.4 update as will be available next month
