Started rooting as per guide on page1.
After flashing 4.4.2, easy root failed to root the device.
Multiple attempts but no success.
Flashed 4.4.3 update and booted system. Realised I has Super User already installed. Uninstalled SU.
Flashed 4.4.2 again and this time easy root rooted the phone.
Flashed 4.4.3 and bingo! SU was installed, updated binaries and phone is now rooted.

[chauhanjayc]

is my guide so much noob frankly that every one succeed
or its too bad that no one is understanding

64 views till now

no feedback

is every think ok out there ???

 

[nanomet]

thanks for sharing this, it works as I did the most same way except making everything packed greatly as what you have done

the best of this was you made all files in one, extremely good for ones do not have 4.4.2 and 4.4.3 ftf files in hands

I guess most of guys do not want to try flash-power off-flash...

 

[Chena_22]

Maybe what you mean is only kernel,not the entire ftf file,right?

what???

 

[Rajiv Patki]

what???

At step 4 you only flash the 4.4.2 kernel, (deselect everything else) not the entire .ftf or you'll end up with 4.4.2 on your phone. Similarly, at step 10 you only need to flash the 4.4.3 kernel, not the entire image.

You forgot to mention that an unlocked bootloader is required to use flashtool.

Also, if you unlock bootloader you lose warranty so backup TA partition before you proceed to keep warranty.

Well written guide. Success here. Rooted now.

Without unlocking your bootloader you cannot use flashtool, I suppose.

i have locked bootloader bro
i do love bravia engine and other sony stuffs :victory:
let me tell you one simple thing in one line
if you wona flash a custom kernal you need unlocked bootloader other then that you can do any thing with locked bootloader
like rooting
flashing custom rom
flashing mod
changing system partition
and a lot more

At the 4 step,you say 4.4.2.ftf,so i suggest you to change it to 4.4.2 kernel..so,maybe there is no missunderstanding for noob users...
