***UPDATE**** I found all the updates online and went one by one. I'm back up to date...and sooooo tired.
This is probably very simple. I unrooted with the SBF method because I had broken root with Easyroot and now have 2.0.1 on my phone. What is the quickest way to get back to FRG22D? I don't want root but I didn't know if I could just go straight from 2.0.1 to 2.2 FRG22d or if I have to update to 2.1 then 2.2 FRG01B then FRG22D. If it is the multi-step process, where can I find the files to update each one? Please let me know. Thanks.
