Like an idiot, without really knowing anything about it, I attempted to root my Galaxy S using the method given here: [X] I followed the instructions exactly as they were written, however after successfully finishing the step starting ODIN with zImage in PDA, my phone boots and gets stuck flashing between the generic "Galaxy S 4G" screen and a "Galaxy S GT I-9000" screen. It never gets any further than that. I tried to hard reset my phone through recovery mode, but I can't select anything. The power button does nothing. I don't know what else to do and I'm really worried that I've managed to royally screw up my phone. Is there any way I can fix this?
