Firmware Rollback problem

I have a WD TV Live plus,  WDBABX0000NBK with firmware    I have attempted to roll back the firmware following the many posts on the forum however I can’t seem to get the device to read the new firmware on the data stick. I’ve tried downloading the zip files a number of times. I have put the ver, fff, and bin files in the root of the data stick. Tried 3 different data sticks, have changed the info in the ver files using notepad to a higher version but it won’t read that there is a new version on the stick. Any help would be appreciated.

Looks like you’re using the firmware from a different player.
