Yes your correct above.

So let me get this right.
1. Load firmware using garminCure.exe and use cure setting
2. Format garmin using recommended software and settings
3. Unplug device and leave it for few minutesrthen switch device on.
4. Plug device back in and copy files to root
5. Using garminCure.exe flash back firmware using original setting.
6.Then unplug device and restart it?

Is this correct?
