So recently I was attempting to root my old s2 (sph-d710) with odin. Half way through the process of downloading, odin displayed an error. Upon restating my phone, it booted straight to the firmware upgrade error. Now whenever I try to use kies (which doesn't recognize it) or just see if the drive shows up on my computer, it doesn't. Windows shows a message that says "usb device not recognized". I've reinstalled the drivers for the phone both before and after the incident with no luck. I've successfully rooted my other s2 using the same method, and I'm upset that its bricked. The phone is in perfect condition, too. So am I out of luck, or does anyone know how to fix this?
