Want to revert back to IOS 8.3 from the 8.4 beta. I also want to not lose my pictures or text/iMessages. Would doing a restore within iTunes in my Mac, with the 8.3 ipsw file work? Or do I need to backup this phone running 8.4 beta 2, enter maintenance mode and do a wipe/restore. Basically don't want to run this beta anymore, want to run 8.3, and try to save/backup whatever I currently have
Would their be any reason or point to perform backup with 8.4 beta 2 prior to wiping and clean installing 8.3?
Not really since you cannot use that backup in 8.3, but it doesn't hurt to have a full backup even of the beta I would say
My preferred approach is as follows: 1) Backup all of your content 2) Put your device in DFU mode 3) Connect to iTunes 4) Download old IPSW file 5) Restore
