I had success with updating on Windows 7 32 bit using the OTG port. Someone else mentioned a hiss from the speaker. I am having this same problem, and I also can't get flash going or uninstalled (tried root explorer). When people mention wiping the device, what is the process? Are they referring to just a factory settings wipe? I was thinking maybe starting from a wipe would help my sound problem. My device is using 126.96.36.199 btw.
