[Q] Soft Bricked s2 gt-i9100 won't charge topic

Hi, I've done goofed

Was trying to update this s2 to ICS from GB using the simple updater from samsung, but had a problem and the device became softbricked.
I could go into download mode only, else the soft brick icon would pop up

I was trying to charge it so i could go and try to recover it... But apparently all it did was discharge the battery :/
Now i can't even get into download mode. The only answer i get from the cellphone is when i plug it into my usb port, he turns on for 2 secs with the softbrick icon then goes off again...

How can i fix this? (Don't know anyone else with an s2, and all i have is an s4 to change batteries)

Thanks
