I'm pretty sure somebody will say "Duh... did you not read...", but I've done a search and found nothing - well, one reference, but it was for info, not a solution.
I have been on F.13 since 23rd November, and my last Fox backup has that date, so I reckon that this backup was the old A12 C.36 version.
I've tried backing up again with OrangeFox-R12.1-Unofficial-OPKONA-OOS13-V14.img and I'm getting the infamous Error 255 failure.
I'd be grateful for any suggestions.
