[Q] Xperia SP boot/flash major problem - General Questions and Answers

Hi all
Please can someone help me. I successfully unlocked bootloader, rooted and updated my Xperia SP to DoomLord's leaked 4.3 ROM, however, something has gone very very wrong. It was working absolutely fine until today when I restarted my phone and it comes up with the Sony logo, Xperia logo and whilst it is booting with the colour stripes, it freezes and reboots. It keeps doing this loop. I can no longer enter CWM nor can I enter fastboot mode. It can go into flashboot mode but not for long enough to do anything with.
Please please please can somebody advise me.

Probably a Bootloop caused by some factor we don't know as of now.
I suggest flashing a stock firmware using Flashtool

Restarting xperia p never gets past the sony logo

My xperia p is rooted and bootloader is unlocked. I tried honami moon walker and didnt like it. So restored it to my old back I took using CWM recovery backup.
I dont know if it got restored properly. I mean I was in honami moon walker and just restored the old backup which is jellybean os. Was it the way to do?
And then I tried to unlock the bootloader to try more roms like cyanogen. but the phone doesnt stay in fastboot mode or the violet light goes faster before I point to the customized interface file in my system. When I pointed, it told "windows was able to find the driver but unable to install it". Cannot find the file specified. I used an application quick boot(Reboot) to get into fastboot mode which was easy. But all in vain. In the process of getting into fastboot mode, I never got out. The screen will be blank.
Then I will try restarting by pressing the power and volume up buttons together and restoring to the old back up I took already.
Now whenever I restart my phone, it gets stuck with the sony logo and it keep restarting. Before trying the power plus volume up combination, it may stay in a blank screen with 2 pixel sized blinks on the two sides of the bottom screen.
So now I am afraid to restart my phone itself. Because it never restarts the phone but gets stuck with the sony logo and then I have to restore it to the old back up.
What should I do? I want to keep my phone rooted and unlock the bootloader and try new roms.

Ok, stay calm, flashing stock ftf will solve the problem

I've used the Sony-recovery-thingy-program.
It works now.
Bootloader unlocked. TWRP flashed. StryFlex MM installed.
