Some common problems for not being able to update the SPD-S are:
- The CF card has not been formatted first in the SPD-S before transferring the factory folder.
- Make sure you have downloaded the "factory restore data file" from the Roland US website, and not the 1.20 "update" file.
- Be sure to copy [only] the unzipped "Factory" folder into the Roland folder on the CF card. If other files are included, the factory restore cannot be completed.
- If a Factory folder already exists in the Roland folder on the CF card, be sure to delete it before transferring the Factory folder into the Roland folder on the CF card.
