[help] failed when try to unlock S500i

hi everyone
yesterday i was trying to unlock my S500i with Setool2Lite, and have followed the step VERY carefull. however everything was good until it's saying something like "trying to reboot the phone.......... fail"
and i can't switch on my phone since then... doesn't do anything when i charge it.
is there anyway to unbrik it???

Did you make a backup of the GDFS when you first started?

Pull out battery for 1 minute,put it back and try to connect with XS++.If XS++ read your phone post log here and backup GDFS (If you didn't do before)

i did backup GDFS
the thing is i can swith on my phone.... any idea?

sorry... i mean i can't switch on my phone...

when XS++ ask me to connect, i hold C and plug in.... nothing happend

back again
it's back online

let me try again
