It’s finally here folks, the official downgrade tool for A5 devices!

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

Check out our tutorial for the step-by-step downgrade instructions inside…

Note: You must have your SHSH blobs for iOS 5.0.1 either stored locally by means of TinyUmbrella, etc., or Cydia must have your 5.0.1 blobs for this downgrade to work successfully.

Step 1: Download the latest version of RedSn0w 0.9.11b1 from our downloads page.

Step 2: Download the latest firmware (5.1.1) for your device from our downloads page, along with the 5.0.1 firmware.

Step 3: Place your device into DFU mode.

Step 4: Run RedSn0w 0.9.11b1, and make sure RedSn0w detects your device in DFU mode. Navigate to Extras > Even more > Restore and click IPSW under the IPSW section. RedSn0w will then 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, it’s time to locate your saved SHSH blobs. If you’ve jailbroken your device before, you should have those available on Cydia, and therefore you can use the Remote option. If you’ve never jailbroken your device before, but you saved your SHSH blobs with a tool like TinyUmbrella, then choose Local and browse your computer for your blobs. We’d recommend clicking the Remote option first.

Step 6: Once your blobs have been verified, there is nothing left for you to do, just let RedSn0w execute the full process. First RedSn0w will install a hacked version of the latest firmware (iOS 5.1.1), and then it will downgrade your firmware to iOS 5.0.1.

Step 7: Upon downgrading 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.

What’s Next?

Most people will want to jailbreak their newly downgraded device. If you’re using an A5 device like the iPad 2, or iPhone 4S, you can now jailbreak using Corona-A5. You can do this directly from RedSn0w. We will have a tutorial that shows you how to jailbreak your A5 device using RedSn0w in the near future. Until then, you can always use a tool like Absinthe to jailbreak as well.

Were you able to downgrade successfully? Have any tips or tricks? Please share them below!

Important: If you rely on a software unlock or SIM interposer for your iPhone, beware! This method will update your baseband, and you could permanently lose your unlock.

  • Well no point in downgrading the new iPad since Pod2g says the jailbreak works on 5.1.1.

    • Hey can u help me I can’t downgrade my iPad 2 cause It doesn’t say it’s connected do you know how to fix that

  • Hello i am trying to downgrade from 5.1.1 to 5.0.1 on iphone 4s. wen i select the ipsw in step 4 i am getting a message that the baseband on the phone will be upgraded . it says like a warnin message.. i am not sure what to do . someone plz let m know..
    ps i have the factory unlocked iphone 4s .. does that have something to do with the baseband issue or what? thanks

      thats the only bad thing about downgrading back to 5.0.1 is that it will update to the newest baseband in the process. You must have 5.1.1 ipsw and 5.0.1 ipsw. In redsn0w you will first select 5.0.1 then it will display a message, hit ok then select the 5.1.1 file. if you did it correct it will then proceed to ask you where your shsh blobs are backed up. It is recomended to choose remotely if you have them on cydia already or point to the tinyumbrella blobs.
      I don’t mind updating to 5.1.1 baseband because Gevey now sell’s a sim unlocker compatible with 5.1.1 firmware.

  • How to save 5.1 shsh blobs..? I still on 5.1 ipad2 …

  • Im stuck in recovery mode now and not sure what to do.

    • Anonymous

      You have to manually put it in DFU mode, first unplug iphone from laptop then simultaneously hold power and home buttons at same time… count to 10.. you will see the power slider appear then disappear, then release power button while continuing to hold home button down for about 15 more seconds. You iphone screen should be all black if done correctly. then plug iphone back in and redsn0w will automatically do the rest. I have done this twice already on same phone, so downgrading/restoring without itunes can be done anytime if you have shsh’s saved. Musclenerd 0wns!!!!!!!!!!!!!!!!!

      • I’m letting itunes do it, I didn’t screw something up right…? :'(

  • I think my phone went into a recovery loop because I think I was going it wrong. So im restoring to 5.1.1 with itunes and wondering if I should try it again.

  • can it be done on iphone 4??

  • i saved shah blobs on tiny umbrella but it says it doesn’t match the build when i locally select them on redsn0w?

    • Graham Macphee

      I have the same problem.

      The blobs save fine in TinyUmbrella and verify in Redsn0w, but when I go to extras > even more > restore and select 5.0.1 then 5.1.1 under IPSW, and select the same SHSH blobs under Local, I get a warning saying the blobs do not match the IPSW.

      Any help would be much appreciated! Thanks

  • What if we created a custom ipsw and instead of pressing the original 5.1.1 we pressed the one with no baseband update and did the downgrade that way. Would it still upgrade baseband

  • it wont let me downlooad it says denied

  • DO NOT USE THIS GUIDE. Terrible instructions, the downgrade didn’t work at all. All this does is wipe your iPhone and force you to set it up again from scratch.

  • it is stuck at restoring system image???

  • Phil Mancini

    Quick question. Right now im on ios 5.1.1 with a 4.12.01 baseband. I know this process will downgrade my ios from 5.1.1 to 5.0.1 because i have the SHSH blobs saved. What im wondering is if I perform this with this new redsnow version, will my baseband stay at 4.12.01 or will it downgrade the baseband in addition to the ios? Thanks
