Not entirely shure what error code I experienced. But I had a similar problem with updating firmware on FP 8 from 1.01 to 2.01.
Maybe try following these steps:
- Reset FP to factory studio one mode
- Disconnect FP and power it off
- Remove/uninstall Universal Control completely
- Download the newest version of UC.
- Reboot PC
- Install new version of UC
- Plug in FP and update firmware to 2.01.
Kind regards
