Don't bother with a clean install. After 5 days of attempting backups from any version I could find, I finally gave up and decided to do a "new iphone" restore. The same problem. As soon as I try to bring over even 1 APP it freezes and I'm forced to restart.
Has anyone figured out how to get your backup onto your iPhone 6 plus after upgrading to IOS 9 beta? Seriously, Ive not been able to use my phone is the last 5 days because it's constantly join a state of doing nothing but freezing. I have let it sit for over 13 hours and still nothing. When I open the force quit window it shows iTunes stopped working, so I am forced to restart over and over and over. I am currently on restart 47. I'm not kidding.
I have tried using my iPhone 6 plus back up - freezes
I've tried using my business partners backup - freezes
I got desperate and tried using my iPad Air 2 - it started, it actually dumped my 630 APPs randmanly onto pages (no longer in assigned folders) and I thought I can deal with that "I'll just reassemble the folders manually - I'm not picky at this point", but sadly after a 13 hour wait only one APP transferred.
HELP! Any suggestions?
