I manually updated my droid with the frg01b(?) build this a.m. My droid 1 is not rooted. This worked just fine. However, when I now try frg22, I get the frg22 e:signature verification failed error and it won't update. I followed all of the usual instructions (e.g., renaming file to update.zip, putting it in root folder, etc.) (and it worked for frg01b(?) so I did the same thing for frg22). Should I have gone straight to frg22 from 2.1? Would that have worked? Shouldn't frg22 install over frg01b?? How can I get rid of the "signature verification failed" error??
