Sunday, May 18, 2008 iPhone 2.0 downgrade to 1.1.4
Recently get into trouble downgrading development iPhone from 2.0 beta back to 1.1.4 release version.
Tried so many different methods and googling for meaning of strange error code… 1604, 1015. Then tried to solve the problem using official suggestions from Apple’s support site. They didn’t work for my case at all…
Finally, after more googling…, found something useful:
- Restore From 2.0 Beta 5 & 4 (This is my solution)
- iphone restore error 1015 – solution..
