1. I've been using ios 10 beta 1 for a while, and backed up my phone via iTunes to icloud. When beta 2 rolled out, I updated it via OVA. 2. Then during installing process, the phone just got stuck after rebooting, at apple logo screen, with the progress bar missing just one bit and never moving. 3. After waiting for an hour, I decided to force quit. Then the phone entered DFU mode. 4. I connected my phone with itunes on Mac. After itunes detected that this phone, I chose "update" instead of "recover". 5. iTunes downloaded ios 9.3.2 and installed fine. All my apps, photos, contacts are there. But all my messages are gone. I tried checking itunes, but it says the only backup I have is the one after downloading ios 9.3.2, though I'm pretty sure I had backups before. I also tried somesoftware called phonerescue and no luck. Anyone can help me? Call me stupid, but those are messages for 5 years, and I really don't want to lose them.
