Ok, I'm foolish or something.
My logs are showing me that I'm not eligible. I am shift-clicking UPDATE, not RESTORE, as that was clearly and repeatedly pointed out. I originally had my gs.apple.com redirected through Saurik's cache, but have tried without that, no change. Has Apple changed something??
