Same here. Same goofy error message over and over. Clicking okay does nothing. Waiting an hour or more after clicking okay does nothing (except run down the battery). Typing the various commands produces screens full of error messages and code, but no access to Piper.
This Piper was a gift for my son, who only had 2 days of use of it (building it) before being directed to do the update. It hasn't worked since.
We're all very frustrated!!
I would appreciate it if the Piper folks would just say "We don't know what's wrong - we're working on it - we'll post when there is a real solution." I don't want to be given any more random commands to try. (I'd rather wait a few days and then do ONE thing that WORKS.)
