- Reboot the calculator in "update mode" (Press the ON key, press the Symb key, release the ON key, BUT KEEP THE Symb key pressed!) it should get you to the "base" update screen with a large HP logo and "HP Prime update mode" display.
On the top left, you should see 2 numbers a 3 and some other number. Can you please report what this number is?
Try it a couple a times and make sure it always report the same number.
This number is the "internal HW revision", which correspond to the values of these CPU IO pins described earlier...

My best guess is that the HW detection mechanism is unreliable... Probably due to some delays in the GPIO lines....
Another possibility is that some machines have been badly manufactured with the wrong IO pin selection, but this is a low probability in my opinion...

Thanks,
Cyrille
