Hello. My device developed an issue with "USB Device Not Recognized" and I am unable to connect to any PC to upgrade my S2 to ICS through Samsung Kies, NOTE it used to work when I first got the device so I'm positive it's not a driver issue. I've tried cleaning it, many different pcs, many different cables. What a piece of crap, it's hardware failure I figure. Can anyone direct me to a way to install the OEM ROM through a micro sd card? Download link anyone?? Thanks!
