K800i problem solving..

[shusakupen]

hi, i am new here at TopSony.. :)

ok, i am not new into modding/flashing SE phones since i own a W810i and a W880i phones..
however, the sister of my friend owns the K800i.. and then she told me that one day, the
phone stops responding and became dead (it cannot be turn on).. i do not have the full
story as to why the phone became dead.. but since i know some on flashing, i checked it
today..

the phone's IR LED only blinks once when i tried to power it up.. what does that mean?
i tried to read the phone using SETool 2 Lite v1.08 and got this line:

*this was done with the 2+5 button press instead of the C button..

then i tried to read the GDFS and got this line after the above lines:

Will backup GDFS now.

can anyone pinpoint the problem? do i need to flash a new FS and MAIN? or probably a
GDFS and/or EROM as well?
