    Hi all,

    I have searched around for some answers, tried various things, but I still cannot get this One X to switch on.

    A quick bit of background, I bought the phone second hand on eBay- seller said they owned it for a week, and dropped it on a carpet floor. The screen popped out, and damaged both the LCD and the digitizer cables.

    When it arrived through the post, I plugged it into the wall- no charging light.

    I plugged it into the computer, it was then recognized as a HTC phone.

    I then fiddled with it, pressing buttons etc. and got it rebooted and heard the boot sound.

    Since then, I've tried to connect it to the computer via ADB so I can view the screen from the computer. However, besides that first time, it no longer appears as HTC phone. I have tried various versions of HTC Sync, and they all fail at the DriverInstaller setup. I have obtained the DriverInstaller seperately, this crashes also.

    I also tried to get it to charge again- the red notification light no longer flashes. After leaving the phone alone for an hour or so, I plugged it back into the laptop, and the red notification light stayed on. I quickly disconnected it and plugged it into the HTC wall charger, the red light stayed on for 10 mins then went off.

    Since, I have purchased and fitted a new screen assembly. Plugging the phone in at the wall does nothing. I haven't seen anything on the screen yet. Plugging it into the USB socket on my laptop does the following on device manager:

    First time, it appears as "Unknown Device" under "Other Devices, and as "Unknown Device" under USB.

    If I then press and hold the power button for 10 seconds (tried 2 mins), or combo of power and volume buttons, it then under "Other Devices" it appears as "APX" and "Unknown Device".

    I have also tried pressing power button and both volume buttons, but no joy.

    It is a UK phone, with "HTC" branding at the top.

    Please note, the phone is currently backless- I don't think this is required to get the phone started, but please let me know if it is.

    Any help or suggestions would be much appreciated.

    Might try rigging up a charging station for the battery independently, and see if it just needs a little go-go juice.

    Will also hook the battery up to a multimeter before I do so- I'm looking forward to the results of that.

    Still open to any advice or suggestions!

    Can't find my multi-meter atm, but I just wired a 3v LED to the battery and it lit up, so it has got some charge in it. However, this thread (http://forum.xda-developers.com/showthread.php?t=1658084) indicates that 3.68v is a 10% charged battery, the battery at full charge is 3.7v.

    Therefore when I find my multi-meter, I'm hoping it will show up as around 3.6775v or less- which the phone classes as completely flat.
