I Bought a HP Prime For $25 and Fixed it!

Flashing the latest firmware as of 2022 on a first generation revision A Prime.
The calculator must have been sitting for a very extended period of time causing the battery to extremely drain and not wanting to charge again.

Many thanks for this tutorial on how to flash the firmware. I was able to flash mine on a Prime Rev A model. Much appreciated. PS You did very well on that Prime purchase!

Timing... Two weeks ago I found a new in plastic HP Prime (firmware 2020) for $20. A year ago found a pristine HP-42S with manuals, box, receipt for $30. And the seller (original owner), stopped on the way to the sale (Craigslist) to spend $7 on new batteries to make sure it worked. So I really got it for $23. There are good things out there if you look for them. $20 for an HP 30b that is now a WP-34s. Appreciate your posts and info that you give.

Did someone adress the flickering Display of G2? Would like to tweak Antialiasing settings too. ok found the Answer : press & hold 'On' 'shift' + '+' or '-' for refresh rate... omg ;-)
