Model: SGH-I727R Android: 2.3.5 Kernel: 18.104.22.168 Build: GINGERBREAD.RUXKJ7 Hi All, I have an SGS2 LTE from Rogers in Canada (same phone as the skyrocket) that has recently developed a USB issue. Whenever the phone is plugged in via USB it will begin charging, but the phone will not recognize a computer and give an option to mount (i.e. the usb icon does not appear in the drawbar). I have tried multiple usb cables including the stock sammy cable, multiple USB ports on each computer, and multiple computers. The USB used to work just fine, so I suspect it is an issue with the port on the phone. The catch is that I rooted the phone a few weeks ago using the SuperOneClick method. The usb issue began happening shortly after - no idea whether the two events are connected. I'm still using the stock ROM, but I'm concerned about trying to warranty the USB port if the phone is rooted, and I'd like to make sure that it is indeed a hardware issue and not related to the rooting. Questions: 1) Any ideas on the USB issue and how to possibly fix it? 2) Any ideas on how to unroot the phone, given that it won't mount via USB? Or advice on how to warranty it? Any help is appreciated!
