'Erase' function doesn't complete in MP terminal

Does anyone here have any advice: I’ve gone through a series of confused firmware updating/deleting/MP reinstalling. Sometimes I can successfully verify firmware, other times the verify fails. Not sure why. Anyway, I’ve been trying to reset the APM 2.6 and erase the EPROM. The Erase command initialized but I never get ‘done’ and terminal basically freezes up. How long should this erase command take? I saw another user saying it completes and says ‘done’ in just a few seconds. After I reset to factory settings, it asks me to press reset on the device, and then I get an endless scrolling log of text. Any ideas on what this is?

Any help would be greatly appreciated.


what firmware?
