Downgrade iOS

Did you want to downgrade your device? Here is the official downgrade tool for A5 devices!

Now you can now downgrade your iPhone 4S, iPad 2, or New iPad (also known as iPad 3) with the latest version of RedSn0w 0.9.11b1. Downgrading iOS will allow you to perform an untethered jailbreak on your iPhone 4S, or iPad 2 running iOS 5.0.1 firmware.

This the our tutorial for the step-by-step downgrade instructions. This tutorial has been tried and tested. But if something goes wrong with your device, then The Apple Bites will not be responsible for that. You are doing this procedure at your own risk. Following video explains the procedure.

Now that you seen the video, we explain the whole procedure, step by step:

STEP 1 – Download RedSn0w 0.9.11b1.

STEP 2 – Download the latest firmware (iOS 5.1.1) for your device along with the 5.0.1 firmware.

STEP 3 – Place your device into Device Firmware Upgrade (DFU) mode.

STEP 4 – Run RedSn0w 0.9.11b1. Make sure RedSn0w detects your device in DFU mode. Navigate to Extras > Even more > Restore. Click IPSW under the IPSW section. RedSn0w will ask you for your iOS 5.0.1 IPSW. Once you locate iOS 5.0.1, RedSn0w will ask your for the latest firmware (iOS 5.1.1).


STEP 5 – Once both firmwares have been validated, now it is time to locate your saved SHSH blobs. If you have jailbroken your device before, you should have those available on Cydia, and therefore you can use the Remote option. If you have never jailbroken your device before, but you saved your SHSH blobs with a tool like TinyUmbrella, then you should choose Local and browse your computer for your blobs. You should click the Remote option first. You cannot downgrade without SHSH blobs.

STEP 6 – Once your blobs have been verified, your task is over. Now you should just let RedSn0w execute the full process. First RedSn0w will install a hacked version of the latest firmware (iOS 5.1.1). Then it will downgrade your firmware to iOS 5.0.1.

STEP 7 – When iOS gets downgraded successfully, you will be presented with a success message. Now all you have to do is setup your device, and verify that you are now on iOS 5.0.1 via Settings > General > About on your device.
