I have been unable to find the "broken" version which might be useful for comparison purposes if it could be found.

Thank you for confirming the continued existence of the problem. My 49g+ is back to the HP firmware and I have acquired another HP50g to run newRPL on!

Well, I wouldn't mind to see the bug solved. It'd be nice to have a backup unit ready, since the HP49G+ can't draw power from the USB port.

I could provide a dump of the bootloader, maybe it could be used to infer where the bug is.

I'm afraid that I have no idea of how to go about this. Claudio tried when the bug was first noticed but wasn't able to get anywhere; unless there is someone somewhere who actually knows what peculiarity in the HP-49g+ causes the problem it clearly isn't easy to find.
