[Q] Xperia P stuck in bootloop! - Sony Xperia P, U, Sola, Go

The problem in my device id that, I replaced my default build.prop with a customized build.prop which i downloaded from the internet
after this whenever i switch on my phone, it gets stuck in the bootloop and shows a complete black screen after the sony logo. I've tried hard resetting and draining the battery but they were of no use. Also tried recovery using flashtool but it can't identify my device!
The status Of my Xperia P:-
Android 4.1.2
Firmware 6.2.A.1.100
Rooted(Bootloader Locked) & no custom ROM installed.. everything is the Stock version!! Only build.prop replaced!!
Can Anyboy please help me out??

do you backup your original build.prop?
if yes just flash it using cwm that you have backup or restore system if you have backup rom
if not just flash the whole JB firmware

If you have the firmware FTF try to flash only system(no wipes, all other excluded) with flashtool not to lose data.
If you updated the phone with PCC or SUS you can create the FTF file yourself.

You must flash the ftf, image via flash tool...

If CWM has adb conectivity you can push missing file and not lose all data
