I remember When I flashed a new version of Marlin on one of my controllers, it failed and went thru some strange process after double checking everything.
Nothing seemed to fix the problem.
Until I re-flashed the same Version a few times, each time restoring The Firmware's defaults, then it started working correctly.
Afterwords I upgraded to newer versions of marlin and have never had any similar occurrences during flashing my firmware to this controller...
