I need some assistance. I have an 8700C I downloaded the 4.2 OS from At&t's website. When I go to install it it goes to where it says waiting for device to initialize and then I get and error from the apploader cannot communicate with the device. The screen is black and the LED flashes red. I noticed everytime it flashes the computer disconnects from it. I have tried using JL cmdr to wipe it and then install it but no matter what it gets the same error failure to communicate with the device and I have to reinstall 4.1. Can anyone please help I would really like to take advantage of the new features of 4.2
