Thanks for your help. I dumped kitkat recovery and tried to flash it, same result. Then I tried to flash it as boot, and also same error message (FAILED (remote: Security is Enable, close 'flash' function !!) ).
That is odd because I previously flashed the boot.img from official roms and it worked...
Don't you think the problem come from the recovery.img I dump and not the phone? Maybe I have another thing to do to "unlock" it?

Ok now I tried to flash boot.img again and it did the same error message. Then I tried to wipe and it did that :
C:\Android>fastboot -w
Erase successful, but not automatically formatting.
File system type not supported.
Erase successful, but not automatically formatting.
File system type not supported.
erasing 'userdata'...
FAILED (remote: Security is Enable, close 'erase' function !!)
finished. total time: 0.018s
Does that mean I can't write anything from fastboot?
So I thought about SAV, but I check with device-info with fastboot and it says that bootloader is indeed still locked, but that the device has been tampered with. I fear that it will void my warranty...
Hi again, it seems that my warranty has expired. So no I hae to find a way by myself to make this work. I think I'll post a bounty on XDA for the one who'll find a way to unbrick my phone. I'll let you know if it works.
I'm sure it's possible. Must be really hard to brick it for good. You can't even imagine what mine has gone through. Flashing roms made for other devices and all.
I still have my PFI but I have another phone now though.
Yeah I'm sure this is possible but it would need me to know erase everything, repartition and flash the right item in the right place. I don't have the knowledge to do this, that's why I'm gonna ask for help on XDA.
