[Q] can I flash a c6603 10.3.A.0.423.ftf firmware work to C6602 ?

can I flash a c6603 10.3.A.0.423.ftf firmware work to C6602 ?

I don't know about 423, but I'm on 253 and not having any problem using 6603 rom on my 6602, it show 6603 on my about phone, and on network mode also show lte option which obviously we don't have it
even I use custom rom based on 6603 rom, and it all work just fine
btw if you want 4.2.2 specialty built for 6602, there is one from taiwan generic unbranded rom, look for it on general xz sub forum

I know for a fact that a 6602 ROM on 6603 causes the phone to become unstables. I noticed that the sim card was also not recognized.

I have been using C6603 firmware on my C6602 from 253 to 407 without any problem. Not sure about 423, but I don't think there should be any problem.

I flashed the C6603 Rom on my C6602 and my xz was stuck on a bootloop..then I flashed the .423 for C6602 by [NUT] and everything was fine..infact my battery life doubled..look at this pic below..it's 4.2.2 and .423..seriously very good battery life improvements..

What did you do to fix this?

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!

Recovery question

If I restore a rom with a different kernel will I need to flash kernel.elf? I'm a little confused about how Xperia kernels actually work, a full explanation would be nice

Nevermind, realised you can just restore normally, mods delete please

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

Installing Ultimate Pure XZ Rom

Hello,
It's about this thread:
http://forum.xda-developers.com/xperia-z/development/rom-ultimate-purexz-v1-t2759467?nocache=1
is it possible to flash this rom via flashtool only or do i need recovery to flash this rom. Now i'm on 4.4.2 .230 stock without root an cwm/twrp. Last time i manually updatet my xperia to the newest rom, which was the 4.4.2, i just flashed the stock rom over the existing rom. After that i did a factory reset.
Thanks a lot for help
