In Search of 15C+ ROM image

I think it needs to be a 12CP version 1 (not the newer versions), see https://www.hpmuseum.org/forum/thread-18285.html

Does anyone know, if the flashing process is the same as with the HP30b?

And are there any specific examples of where a later Arm powered 12C has been flashed?

I have a couple of Arm 12c's around the house somewhere and don't mind bricking one of them should the process go wrong, but I'd like to know a little more about the specifics of flashing an Arm 12C.
