Not sure what downlaods you are using. These steps include the files that should work.
- Upload PREPR4TOR6_0.1-x86.bin as an add-on using the ReadyNAS web gui, but do not reboot afterwards (avoids the need to do manual factory resets)
- Upload R4toR6_6.9.5.bin using the ReadyNAS web gui firmware update
- After you upload the addon+firmware and reboot, it will update the firmware and start a factory default.
- Go through the setup process on the converted NAS
- Update the NAS to the current OS 6 (check for updates will NOT work).
