We have tracked down the issue with the upgrade process on 3.2.8.
Until we get a fix in, the recommended upgrade path is to use the force_upgrade process...
1) create a force_upgrade folder on the top level of your SSD
2) drag the upgrade.bin file into the force_upgrade folder
3) insert SSD into camera
4) power up the camera and wait for upgrade to complete. (the green pwr/rec LED's will flash while upgrading and the camera will automatically shut down)
everything will be restored to the proper 3.2.8 settings on the next power cycle.
if you decide to downgrade from 3.2.8 to 3.0.x, we recommend the same procedure.
