HP PRIME Completely DEAD ?

[ChrisR]

Hi,

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 attempt the screen now won't illuminate, the calculator is no longer recognised via USB and to all intents appears completely dead/inert.

I've tried the F,O,C reset trick. The Symb reset trick, the reset by itself all with combinations of USB powered, battery powered, both battery and USB powered. And nothing. Dead!

Are there any options left now other than to ceremoniously and with decorum place it into the recyling bin? (I'd prefer not to - but it looks like that's where it may have to go)

Chris
