1. insert battery (cold start)
2. press all keys and ensure they register
3. ON-CLR sequence to get into "MEMORY LOST" state
4. could just play around w/ some simple calculations
... new steps here
5. press ON to turn off (put to sleep) calculator
6. do a TAN+ON warm start (i.e. hold TAN and press ON to turn calculator on)

I received my NP-41 this morning and followed the suggested steps without any issues.

I have the necessary USB to serial adapter, cable and male-to-male header pins. Please let me know when you have a potential fix to the firmware and I'll be glad to beta test.

Warmest regards,
