iPhone - Downgrade - How can I downgrade from iPhone firmware 3.1?
✍: Guest
As we reported earlier, many iPhone users have encountered problems with the iPhone 3.1 firmware upgrade. Until Apple comes out with fixes for these bugs, the solution may be a downgrade to earlier software versions.
If you're having problems with the iPhone 3.1 update, try this restore to downgrade to iPhone OS 3.0.1:
- Download the correct iPhone 3.0.1 IPSW file for your iPhone: http://www.quickpwn.com/2009/07/iphone-3-0-1.html has the IPSW files from Apple under "iPhone 3.0.1 Download Links."
- Make sure your iPhone is connected to the computer.
- Open iTunes, then hold down "Option" and select "Restore" on your Mac (Shift and Restore in Windows) when your iPhone mounts.
- Choose the downloaded 3.0.1 IPSW file.
- This will restore your iPhone to OS 3.0.1.
- Now you can restore to your latest iPhone backup.
