How long does it take to Erase All Content and Settings on iPhone 5? Corporate policy at my job requires a lockscreen passcode on iDevices with corporate email on them, even personal. Yesterday, I set my password, then 5 minutes later had to use it. When I entered it, the phone says it was wrong. I entered it the magic number of wrong times, and so began the Great Purge of 2013 (data wiped from device). I stopped this from finishing (power + home button until it shut down).

I'm willing to let this process complete, as long as I'll still be at 6.1.2 when it finishes. Does anyone know how long the process takes with a 16GB iPhone 5 (A1428)? I've read the Apple article about it, which tells me that it supports hardware encryption, and the process should only take minutes, but I let it go for about 2 hours, and nothing. I wonder if, by "minutes" Apple means like 600 minutes or something. 

Does jailbreaking affect the amount of time the wipe takes? Any input would be helpful. I'm just really trying to avoid 6.1.4.
So I verified that deleting the hardware encryption key should not take very long at all. My problem was that the phone was jailbroken on 6.1.2 (not sure what the EXACT problem was). By following this procedure, I was able to delete all content and settings manually, with the file browsers iFunbox and iTools. Unfortunately, it didn't delete the errant configuration profile that locked me out of my phone, so I still had to update to 6.1.4.

I wish I had the time to investigate the issue further, but as this is my primary phone, I just needed it back operational.
