[Q] Help! Can't UNBRICK my X10i ! - XPERIA X10 Q&A, Help & Troubleshooting

hi there,
My phone is completely dead, and not start at all, I can't even see my Screen (LCD) light blinking even once.
Only when I press power, it vibrates, that's it.
I tried SEUS, and even SEUS downloaded 2.1, SE PC suite; SEUS choose Factory + Reset, then it fails; SE PC suite choose Phone Repair, still fails...
It fails every time.
So, I searched for XIOFUB.rar, extracted ---> get X10Flash_Unbrick, when flashing, I got the message INFO like:
INFO: <<<ERR_SEVERITY="MAJOR";ERR_CLASS="PROTOCOL_CLASS";ERR_STATIC="UNVALID_COMMAND";ERR_DYNAMIC="";
below is the output.

Maybe find a way to charge the battery? I know seus wont do anything if you dont have at least 50% battery life. Are you able to plug your phone into the wall charger and get some battery life charged up?
If seus wont work for you, you can also download the flashtool and flash the firmware back to your phone.

my xperia has the same problem. Still looking for a solution

I think that's CPU or Flash memory problem. Contact service for solution.
