newRPL: [UPDATED April 27-2017] Firmware for testing available for download

[Helix]

Just for information:
I've tried to install the last version of newRPL on my HP50g, and this time I've had a lot of difficulties.

After the traditional update and reset procedure, the screen displayed "exception data abort".
CONT, EXIT, shift WARMSTART and Shift RESET returned to the same screen.
OFF didn't work.
ON-A-F didn't work either.
Reset with a paperclip returned to the same screen.
Removing a battery didn't work, because as soon as the battery was inserted, the calculator still displayed the same screen.

I've tried to install previous versions of newRPL that was saved in my PC, and to my surprise they didn't work either, showing the same problem. Flashing the calculator with the original HP ROM worked perfectly, but flashing again with newRPL returned to the same problem, but with a different screen: "exception : corrupted MMU".

I've found a solution: pressing Shift RESET, and very very quickly pressing ON-A-F. It was quite challenging, but this time I could wipe the memory. Since the calculator seems to work normally with the last version of newRPL.
