    Hi

    I have recently been given a 9780 ( no history )that has black screen just flashes twice when plugged into the mains.
    The battery that came with the phone is dead, ive tried another battery but when in the phone all i get is 2 flashes 3 second wait the 2 flashes et....
    I've spent a couple of days googling the fault and have downloaded and run as much software as i can with no success. Ive tried the phone on 3 pc's ( win 7 ) , i havent yet tried win xp.

    The phone does show up in device manager as a Blackberry phone 9780
    Desktop software detects the phone as a 9700 it cant connect to the device or repair it
    Apploader displays USB-PIN UNKNOWN but when click next it waits a few seconds then diconects the usb (have deleted xml file & stopped bb processes.
    BBSAK and JL-commander cannot find the phone, even though its visible in device manager
    Blackberry Master Control program attempts to nuke & wipe however it diconnects the usb when executing and displays USB driver abort.

    I have read post all different forums of people having this problem but am banging my head when it comes down to a solution.
    I am lead to believe that the 2 red lights ( 11000 ) fault is no os loaded but i have a gut feeling that someones probably fried the charging chip.

    Any ideas, please

    Thanks in advance

    Dave.

    if you've tried the reloading of OS with the battery out and still not working, I can say it's a faulty hardware

    Im thinking the same.

    I stripped the phone down today, theres no sign of water damage, ive given it a good clean with ipa, just in case, my last ditch will be a brand new battery which ive ordered. My gut feeling is this is dead !
