So yeah - Fates now has a separate UPDATE from the original norns and norns shield. This newest 201115 update is not yet available on Fates.
If you were on an older system version (before 200218), then the UPDATE on device will have bricked your system and you will need to re-install from disk image with the instructions you linked above (instructions here)
If you were on 200218 or later, the menu option for SYSTEM > UPDATE should work and would get you to version 201029.
Important note for support - All Fates support requests should go in this thread and not in the main norns threads. If its a general scripting question and you’re not sure, then be clear and identify what hardware you’re using so there’s no confusion.
