HP Prime update freezes at 18%

HP Prime
Microsoft Windows 10 (64-bit)

Hello everybody...

I have an HP Prime calculator, almost never used, maybe 5 hours total use. I cannot connect it to the PC, I have Windows 8.1 and after installing the connectivity kit, it never recognized the calculator, like if I never connected it on the USB. I tried on another computer, Windows 10, installed the C.K. and it recognized the calculator... the first time, it asked if I wanted to update the firmware, I said yes and the process started but stopped at 18%. After waiting for about 1 hour, I decided to try again so disconnected the HP and sterted it all over again, only now the calculator would not start, if reseted, it went only to a screen with x2+y2=1 and no more, if reseted or taking out the battery for a while, when turned on again, the same screen. If reseted using the paper clip and the SYMB key, I got a screen with HP Prime recovering mode V16 and was able to try again the firmware update but it stopped again at 18% (I tried 6 times, waiting as much as 3 hours, nothing happened). Now the calculator does not start, just the X2+y2=1 screen or HP Prime recovery screen, but no reset menu at all, I tried taking out the battery, the clip reset with SYMB, clip + A+C+O and clip alone, and A+C+O+On key... nothing. Hp Prime is the more expensive paperweight I have bought in my entire life.

Hello, thanks for answering!

 

My mistake, I have been trying with F+C+O, not the A... it have not worked. I uninstalled the connectivity kit and reinstalled it already, I even tried an old version for 32Bits (another forum suggested that) and didn´t work at all... My next step is to change to another computer  with windows 7 and try there. I will let you know what happened.

 

Again thank you for taking time to look into my problem.

Well, I was finally able to recover the calculator. I changed to a HP laptop where I installed the comm. Kit and repeated the process there, and it worked the first time !!! 

The laptop has installed Windows 10, I have no idea what made the difference.

 

Thanks for your help.
