How to backup stock kernel 12.1.a.0.266 - Xperia SP Q&A, Help & Troubleshooting

Hello friends,
I was searching for Rooting my Xperia SP 4.3 Jelly bean by doomlord's method but i found it that user are having issue after using doomlord's kernel so i am thinking after rooting my Xperis SP i will restore back the original kernel. But i have issue how do i backup original kernel before proceeding to all this method ?
Please help.
Thanks

You must have root for it or if you had downloaded the 4.3 ftf you must uncheck everything but kernel when flashing

Thanks for your support. But i have C5302 Model. and yours is C5303 so i think stock kernel might be different. I need stock kernel of C5302 4.3 android.
Thanks

You can download the 4.3 ftf for C5302, there are tons of them in general section, i think thats the only way.
Cheers

Can any one give me a ftf kernel for my Xperia TX 7.0.A.3.212?

You might want to try this one: http://forum.xda-developers.com/showthread.php?t=2040966. (There are more in the all in one thread)
Btw: an ftf is usually a complete dump and not just the kernel.

Why don't you root it afterwards: http://forum.xda-developers.com/showthread.php?t=2327472
The thread says it's only tested for 9.1.B.1.67 and 9.1.B.0.411. But you might want to install a newer firmware anyway while you are at it. Isn't 7.0.A.3.212 ancient? (not sure, because I have a T - and the 7-series firmware versions for the T were still Ice Cream Sandwich).
I just want to root it.....

Can I flash any generic firmware onto UK phone

O2 don't seem to be releasing 4.3 anytime soon so wondering can I flash some generic on without root and not affect my phone in anyway?

I think you should exclude babeband from flashing, just to be sure.

I git my Z1 from O2 UK and flashed it straight to generic UK firmware and I've never had any issues.

install drivers from c:\flashtool\drivers
Run flashtool

choose flashmode
browse to where you saved the ftf file
attach phone in flashmode when prompted

Root a 4.2 or below ROM - Search for the root methods in the other Z forums as there's more than one method
then download a 4.3 ROM and follow the instructions

Also its better if you post the questions in the "Xperia SP Q&A, Help & Troubleshooting" section.

You don't say which firmware version you're running. It's best to provide details when asking for help.
If you're running anything up to and including 4.4.2 (10.5.A.0.230), then just use towelroot.
If you're on 4.4.4 (10.5.1.A.0.283 or 10.5.1.A.0.292) then it's slightly more complicated. Follow my guide here.
