Phone Boot Loop Sony Xperia T after trying install CM11 (mint)

Hello Everyone,

As a hobby I've tried to install FXP-52 CM11 mint version on my smartphone (flashed by DooMLoRD_Easy-Rooting-Toolkit_v18) on the recovery clockwork mod but the installation has been aborted in the beggining and now the screen stills on the sony logo and I just can power off my phone in use power and volume high buttons concomitantly.
A important thing to say is that I can't access the bootloader in using power and volume down buttons AND by the PC way (flashtool or "cmd")
So I think I can reboot my phone in the PC way only but PC companion is already updated and don't recognize the device.
I don't change my kernel version anyway.

It is my only cellphone and it really maters to me,

Thank you for your help ...

PS : I conserved a bit of battery, 80 % minimum.yet

EDIT : I was on 9.A.1.145 i think
Flashtools don't recognize the device and the "cmd" too
I don't know if my bootloader is unlocked ...
