Downgrade iPhone 4S, iPad 2 and iPad 3

Premise: who owns iPhone 4S and iPad 2 can go back to iOS 5.0 at most new iPad 3, at most it can go back to iOS 5.1.


CAUTION: if you have an iPhone 4S imported from abroad, DO NOT carry out the procedure, which will update the baseband of your device and make it impossible to use the telephone part.

Let's start with the guide:

  1. start the new redsn0w 0.9.11b1
  2. connect your iOS device to your PC or Mac using the appropriate cable
  3. click on the extras button
  4. click on the last even more button
  5. click on the restore button
  6. there are now 3 different options. The IPSW button, and the two local and remote. Click on IPSW and select the firmware you want to downgrade
  7. if a window appears that says additional IPSW required, you must manually select the firmware IPSW file installed on the device from the PC
  8. if you have saved the shsh certificate of the firmware to restore, just click on local and select this file. If you haven't saved the club, move on to the next step
  9. click on the remote button if the shsh blobs are saved on Cydia. Redsn0w automatically recovers lshsh and puts the iOS device in recovery mode to recover the necessary files from the Cydia servers
  10. click on the next button
  11. at this point, redsn0w adds lshsh to the previously selected iOS firmware and creates a sort of custom firmware that will be automatically restored (yes, without user intervention and without the help of iTunes!). You just have to wait for the process to end (the time varies depending on your PC / Mac).
  12. After several minutes, the process will be completed.

But what is the firmware downgrade of iPhone, iPad and iPod for?

The purpose of this downgrade of iPhone 4S, iPad 2 and iPad 3 with the new version of redsn0w that of restore a certain iOS firmwareto perform the jailbreak procedure on it.

In case of iPhone 4S and iPad 2 thanks to Absinthe the complete JB for iOS 5.0.1 can be run. For the new iPd 3, however, at the moment it is not possible to jailbreak on any firmware.
