HP Forums

I have found the three-party firmware, but it doesn't work with the latest firmware. The calculator just went black after I had flashed the firmware into it. So how can I run a binary file with the latest firmware?

Excuse me, where have you found the three- party firmware?. Thank you.

But indeed, you can't run native programs with the official firmware.

Looks like I'll have to dust off my disemboweled HP Prime. Actually, I'll have to write a hardware-level emulator first because I'm not going back to the "blind debugging and flashing under Windows" endless cycle ever again.

Can you open a GitHub issue with:

• hardware revision (DVT, HW-A or HW-C) ;
• firmware version ;
• description of symptoms ;
• link to this thread ;
  

so that I can keep track of this?
