I have a 5s 16 GB currently on 7.1.2 that I plan to upgrade to 8.1 using the full clean method. Despite a lot of references to this method I haven't been able to find a single consistent list of exactly what the steps in the "clean" method are. This is what I have so far. I would appreciate the review, comment, and improvement by knowledgeable MR forum readers Delete unwanted pictures and music Upgrade iTunes to latest version Back up phone via iTunes Back up phone 2nd time via iTunes using encryption password (this is the backup that will be restored) Disconnect phone from iTunes Settings / Genera l /Reset / Erase All Content and Settings Reattach to iTunes At this point, will iTunes suggest upgrading to 8.1? Restore from encrypted backup Two things I am not clear on: At what point is the actual upgrade to 8.1 done? Presumably 8.1 can import an encrypted backup from 7.1.2 and convert it as needed? Any advice would be appreciated!
