Make sure your phone is fully charged (minimum recommended value 70%). Now follow these steps below :

1) Connect your phone in MTP (Media Transfer Port) mode with your PC.
2) Open PC Companion and wait phone to be detected, after detection go to update option and click Repair My Phone/Tablet.
3) Leave the device until repair finishes.

Another method :

1) Flash 4.1.2 firmware from here Xperia SP 4.1.2
2) Flash it via Flashtool.
3) Extract the Kernel.sin from the stock FTF file (Android 4.3) you previously have downloaded.
4) Open Flashtool (By Androxyde) and then open tools->sin editior and select Kernel.sin where ever you extracted it.
5) Click extract data and wait.
6) Once you get the kernel.elf file rename it to boot.img.
7) Flash it as kernel via Flashtool.
8) Now select the stock FTF (Android 4.3) you downloaded and then before flashing look into right side you'll see an exclude option box.
9) Exclude kernel.sin and flash the FTF.

Check and see if any of the above methods work for you.
Hit thanks if I helped you. :)

Hi bro,

As you described here, is it possible to run 4.1 kernel on 4.3 without problems? :confused:
