A way to install and run iOS 6 beta without a developer account was recently discovered. For those of you who have already installed it, found it full of typical beta bugs and decided this first release isn’t what you want, there’s a way to downgrade back to iOS 5.1.1.
Most developers know how to do this already, but for those who don’t, the process is easy enough. Downgrading is the same for the iPhone, iPad, or iPod touch. Just follow these directions:
- Turn the device off, connect it to the computer via USB, and launch iTunes
- Place the iOS device into DFU mode: with the device off, hold down the Power and Home buttons together for 10 seconds then release the power button, continue holding the Home button until iTunes notifies you of a device in recovery mode being detected. The device’s screen should stay black as if turned off.
- Restore within iTunes through either method a or b:
a: Restore from the iOS 5.1.1 backup you made prior to installing iOS 6 beta
b: Restore to iOS 5.1.1 IPSW by Option-Clicking the “Restore” button, and then restore from iCloud backup when finished
- Let iTunes restore back to iOS 5.1.1; the device will reboot when finished
Usually it’s not as easy to downgrade between iOS versions, but since Apple is still signing iOS 5.1.1, it allows you to downgrade without much trouble.
If you get errors when trying to restore, you probably have Apple’s servers blocked in your hosts file. This is pretty common for people who have jailbroken a device at some point. Just remove the blocks to Apple’s servers and hosts and try again.
