Why SE C902 won't turn on?

[hansanders]

My Sony Ericsson C902 won't turn on. It's totally not responding.
The phone is recognized by seus and a2 loader by holding down 2+5 (not c?).

Here the log of a2 loader:

So, you must use SEUS to upgarde a new Firmware (if it offerts you this option) or reinstall again your current firmware (if it doesn't offerta new firmware)

With wich files can i flash?

if all these procedures don't solve your problem, you can apply Full Flash procedure; in this case you must use a data packet (FS, MAIN and CDA), here the files:

MAIN: C902_R3EA038_MAIN_GENERIC_AO_RED52

FS: C902_R3EA038_FS_WESTERN-EUROPE_RED52

and CDA:
c902custpack choose one according to your country and Phone Operator.

I recommend after Full Flash procedure, update your phone through SEUS.
