You need flashtool, put the stock rom.ftf in flashtool/firmwares and just flash the official stock rom via flashtool mate.
Thank you so much. I had actually done the boot loader unlock, will I have to do something about it , I had changed kernel also I think during the procedure,

Search xperia p android developmemt section for stock rom and kernel. Also I dont think you will need to relock bootloader again for using sus or pcc.but I am not sure.just put the stock firmware and try.
If I helped you hit thanks

It doesnt matter your bootloader is unlocked, just flash the original sony rom and thats it. The kernel is inside of it.
Search xperia p section and you will find the rom buddy.
Got it dudes, I got it, everything is fine now
Thousand thanks...

Thanx...
Do I need to root seperately??
Sent from my ST25i using xda premium
Not sure what you meant mate. If your rom is already rooted, flashing a kernel wont change it
Ya I know
But I was just asking,
Was thinking to flash it over stock!!

you will not lose root unless you flash a stock .ftf file or a rom that (somehow) is not pre rooted

New firmware or new rom?
If that rom is pre-rooted then it is rooted.
