Thanks for the n00b lecture, but I already knew I should have had a 2.2 nandroid as well.
I don't post a whole lot, but I've reflashed on my Hero and Galaxy so much it takes about 30mins to get the phone back like I want it starting from scratch with Titanium and such with my work computer. However, at 1:30 in the morning and being away from my normal computer, I didn't have all the resources available to reinstall everything quickly.... Hence the question if anyone else had seen something similar.
Anyway, even after getting it fixed (by starting from scratch with ODIN) I still had an issue later of the phone going back and sticking in Airplane mode. Searching the web it looks like the Galaxy has a bug where this can occur from time to time for several people. Since getting back in full coverage and reflashing (again) I haven't had anymore issues, but will update if I find the root cause. I'm suspecting it has something to do with the radio unable to register fully in bad coverage causing it to hang.
BTW Nandroid does NOT seem to work correctly between versions 2.1 and 2.2 unless you also reflash the voodoo kernel for DJ20 even if you had the Voodoo kernel in what you nandroided.
P.S. I'd love to volunteer to help with some development if I ever get some time. Granted I haven't developed for phones in about 7 years and haven't developed period in about 4 I think I could catch on fairly easily.
