[Q] Help Unbrick my xperia P

[maanleo]

Hi everyone...

Yesterday my sxp was working alright when i decided to relock bootloader. So I used relock ftf file and flashed it via flashtool. Now I used SUS to update my phone. But when i pressed Vol down and plugged in usb, i just got a red led and sus didn't detect my phone. I thoght battery is not enough, now the situation is:

***when i connect my phone to wall socket, red led turn on for few seconds,then it turn into green led for 1-2 second and then led goes off.
***if i try to use power + vol up/down....no vibration...only blinking red led for couple of seconds
***phone is not being detected by SUS or flashtool, as connecting via usb holding vol down button only gives red led.

I am stuck here. Any help is appreciated.

Well there is some progress...

when i connect the phone via usb to pc red led turn on no matter i push vol down button or not and phone does not get recognized in flashtool or SUS....

but after few minutes green led turns on and phone gets recognized by flashtool and SUS as in flashmode....
but while SUS is downloading led turns off phone gets disconnected and SUS gives error.

Its even better if you flash stock before you flash relock tft. Stock kernel works with locked and unlocked bootloader. But if you are using custom or cm kernel, then it will cause exactly what happened to you...

Ohai there... Had this problem myself, and i found out that you have to flash stock firmware after relocking... This also happend to my XGo, and flashing stock firmware fixed the problem! Hope you have a working Xperia P afterwards!
Also charge your phone over night before flashing!

If u cant turn ur phone after hours of charging. ..Take out battery...charge with auto charger...put it on..it will vibrate than flash it...
