On ASR8400, 2MB
FTP said there were no files on the router.
Ended up being locked out and had to use USB Flash Repair to get back to normal.
Several errors in the TOC (left hand pane)
Was able to revert to 184.108.40.206.F-3.2.1_021804 via USB + Run.bat
This time the router was powered down immediately after the upgrade and switched off for 30 seconds
