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 )

Return to stock, But no TA backup.

Hi, I want to return to stock. I have U/B running ihackers 2.1 but i don't have TA backup. I don't mind not relocking bootloader but just want to return to stock to sell my Z1. Can i just flash a ftf with flash tool to return to stock or does not having TA matter?
Yes. You can go back to stock flashing stock FTF without TA and with UL.
Thank you. Would you recommend flashing. 290 or 136

136. It was meant to fix few bugs so better than this one there isn't.

If you want to be sure that the phone will be covered by warranty, you have to flash back any stock FTF for your model.

Thats all? Then i can receive the updates form Sony again an can i use Sony pc companion?
What do i with the kernel?
Stock firmware will flash stock kernel.
If you have to backup you can also lock bootloader.
And yes, after that you can install anything from PCC

I have a question related to this topic.
I had Doomlord`s custom kernel v21 with root and unlocked bootloader.
Im trying to revert back to stock rom and kernel via flashtool and generic nordic rom.
Flashing goes alright but after flashing when i try update my phone either OTA or trough pc companion they both failed.
pc companion says that i have modified sony and i guess it same with OTA update.
Should i do something also, because i thought flashing with stock rom should revert all but bootoader back to original.
Thanks in advance.
You cannot use OTA or Pccompanion with an unlocked bootloader,
You should flash the latest version FTF using flashtool
