    Two nights ago I was trying to adb in to my phone but "adb devices" said that the phone was there, but "offline". I updated ADK and went to bed.

    Last night the phone charges fine but now it will not show up as a device at all. The PC does not even look for the software and show up as a bad device. I think this is hardware, because this is what I have tried after digging around in the forums:


    • different cables - my phone bad, wife's Desire S is fine
    • different PCs - my phone bad, wife's Desire S is fine
    • different ROMs with full wipe - IceColdSandwich and Android Revolution draw a blank. Revolution detected the USB insertion and said that it was going in to USB hard disk mode, but that PC did nothing.
    • cleaned out the port with an air jet and a pin (there was nothing to pull out).
    • rebooted in fastboot, "fastboot getvar all" did nothing other than "< waiting for device>"

    adb over WiFi works, and I guess I could FTP files to the phone, but it is all a bit mysterious. The phone has not been dropped, not have I done anything different with it. USB debugging used to toggle an insertion event on the PC but not any more. The only "different" thing I did that night was try adb over wifi to see if I could get in to the phone. I have since uninstalled that widget.

    Frustrating. I wonder if there is any simple setting that might have ticked itself. :thinking:

    My computer sees it but when I try to open the phone to view files it says it's not there.

    Not quite sure what you are saying here. That sounds like a different problem.

    My phone is still displaying the same symptoms. I am more and more convinced it is h/w.:(
