Hi,
I recently acquired a Prime (G8X92AA) which wouldn't go further than the HP Logo screen on startup.
I tried to reflash the firmware using the connectivity kit with the prime in V13 recovery mode. Each time the upload would freeze at 39% and then error out with error number (112) I'm using the official HP USB cable.
I tired different USB ports and as well another pc with exactly the same results.
On the final reflash attempt (which again failed at 39%) the screen will now no longer illuminate and the calculator is no longer recognised via USB. To all intents it appears completely dead/inert.
Prior to this I had tried the F,O,C reset trick. The Symb reset trick, the hard reset, all with combinations of USB powered, battery powered, both battery and USB powered.
Are there any options left?
Chris
