iphone How to Downgrade Your iPhone, iPad, or iPod Touch

What is Downgrading?

Downgrading is the process of installing a previous version of iOS, the software on your iDevice. In order to fight fragmentation (and other things), Apple does not allow users to downgrade their iDevice software. So the jailbreak community had to come up with their own solution. Note: Downgrading firmware will not downgrade your baseband or “modem firmware” for unlocks

If you’ve ever updated your iPhone’s software through iTunes before, you’ve probably noticed the “verifying restore with Apple” message before. That’s iTunes, talking with Apple’s servers, to make sure you are installing the newest version of iOS.

How to Downgrade

1. Step 1: place your iDevice into DFU mode
2. Step 2: Check to ensure that the Hosts file doesn’t contain any Apple references.
3. Step 3: Open RedSn0w, select Extras, and PwnedDFU. Your iDevice screen should remain black
4. Step 4: Open TinyUmbrella, and select “Start TSS Server
5. Step 5: Open iTunes and hold Option while clicking Restore (it’s Shift and Restore in Windows) then select your iOS 4.3.3 firmware file.
6. Step 6: If you get a Recovery Error (1), close iTunes completely
7. Step 7: In TinyUmbrella click on Advanced and deselect “Set Hosts to Cydia on Exit…” Exit out of TinyUmbrella
8. Step 8: Open RedSn0w, select, Extras, and Recovery fix. The device should appear to be jailbreaking. Afterwards it will return to the black screen
9. Step 9: Again, open RedSn0w, select Extras, and Just boot. Once your device boots you should see a Pwnapple logo, and eventually it will boot completely on the downgraded firmware.
10. Step 10: Open up iTunes to activate your iDevice.
