I have a user that came to me this morning with an 8110 that no longer works. It will not power on and when the battery is inserted all it will do is blink the red light every 5 seconds (5 on 5 off). When it is connected to a PC via USB it keeps picking up and dropping the connection in sync with the lights. In device manager Blackberry Smartphone appears and disappears every 5 seconds.
I have tried using jl_cmder to wipe the handheld, but it doesnt seem to be connecting to the device as I am not getting error 507. Other than the red light the device looks completely dead.
I have also tried using apploader via BBDM and loader with the /nojvm option, both of which produce the same result - when they are launched I am able to connect the device when I see USB UNKNOWN, at which point the BB seems to have a solid connection to the PC via USB (checking device manager shows Blackberry Smartphone). It remains connected like this as "Load JVM and system software" is running, but as soon as it changes to the next menu item of "Wait for device initialization" the connection keeps dropping every 5 seconds again.
Can anyone help with this device as I am pretty much at my wits end with it now??
