Very Dead S500i :( Help?

I had modded this phone to a w580i a while ago, everything has been find when today my friend took out my battery, and when i put it back in there was just a red light flashing, i did a bit of research and people told me its the erom or gdfs, well id love to fix it but none of the programs seem to be able to read it, using c or 2+5 :S
XSS just hangs
setool says i have a fatal error reading gdfs and wont repair or flash the main etc
what can i do?

edit: setool error is:
Will backup GDFS now.

You Should can use XS++ and Flash Main and FS

xss just hangs:

Must use Setool.

1. Reinsert battery and do NOT turn on phone!
2. Start Setool and click Identify
3. Hold 2 and 5 together and in the meantime put the USB cable.
When hear that sound (though that connects USB flash memory) disconnect USB cable, reinsert battery and do NOT turn on phone!
4. Start XS++ v3.1 and click Connect.
5. Hold "C" button in the meantime put the USB cable.
6. Flash only Main, then again disconnect USB cable, reinsert battery and now can turn on phone - work fine as before.

if you are very shure that battery is ok ( more than 3,8V ) then your phone GDFS area damaged and only " dreambox " using testpoint method can repair it ( SEtool or any other tool can't repair it) .

how much does dreambox cost?

about 250 euros
