Help = my phone crashed last night and is now in a booting loop to the nokia logo. I have followed all the instructions to flash the device. I cannot get the USB logo on the screen following the instructions. I can get the USB icon on when the device is powered with the wall charger, but not to the USB on the computer. I have tried Win7 and Vista and Ubuntu with no luck. Could this be a faulty battery causing it? Does anyone have any ideas. Thanks
