[SOLVED No way to recover the phone :(
SOLVED : BATTERY WAS DRAINED AT THE MAX, never seen that.
This kind of discussion has already been mentionned but i didn't found anything (may be bad search).
After flashing a rom (PureIon rom) through CMW and without the requiered kernel (in this case the .211 or something like that was needed) the phone was stuck on boot "Sony".
A this moment i cannot enter neither in flash mode or fastboot mode.
If i keep it on the wall poser supply, it stays turned off with red led (not blinking, constant), after a while he automatically turns on and stuck on the Sony logo.
If I just shut off (simple keep power+volume up) there is no way to turn on the phone, i have to re-plug the phone against the wall power supply and wait.
The hard reset (3 vibrations after keeping 10sec the power+vol up) is not working anymore
Someone has already had this king of behaviour ?
Thank you in advance.
