I tried to root my phone a couple weeks ago, and was unsuccessful. I have found another way that I would like to try, but am unable to. I need to first update the usb driver, and when I try to load my phone in the HBOOT screen my phone tries to find this PC36DIAG.ZIP file and is unable to load it. I have formatted my SD card numerous times and cleared all data off my phone. Nothing I do seems to get this off my phone. Please help!
