How to downgrade pre-A5 devices easily with RedSn0w

By , Oct 15, 2012

RedSn0w 0.9.15b1 was a gargantuan update. In fact, we’re still trudging through all of the new features. One new addition that has us really excited is the new direct restore option for pre-A5 devices.

This new restore option allows you to downgrade your device without having to fool with host files, stitching, Pwned DFU, iTunes, or anything else that made downgrading so incredibly cumbersome in the past.

We’ve made a step-by-step tutorial that shows you how to use this new restore feature, along with getting by those pesky Mismatched APTicket errors. Check inside for the full tutorial.

Note: You must have your SHSH blobs saved either locally, or on Cydia for the firmware you wish to downgrade to. If you do not have the blobs saved on Cydia or your local machine, you will not be able to downgrade. This is for pre-A5 devices only, so device like the iPad 2, iPhone 4S, and newer cannot be downgraded using this method.

Step 1: Download RedSn0w 0.9.15b1 or newer from our downloads page and open it.

Step 2: Connect your iOS device, and place it into DFU mode.

Step 3: Ensure that RedSn0w detects your device in DFU mode at the bottom of the main RedSn0w page. Click Extras > Even more > Restore > IPSW, and select the IPSW firmware file that you want to restore to. If you don’t have the right firmware file on your machine, you can download firmware files from our downloads page. RedSn0w should process the IPSW file.

Step 4: After the IPSW is processed and identified, you will be prompted to preserve your baseband. If you’re on an unlockable baseband, and you rely on UltraSn0w or a SIM interposer for an unlock, you may want to preserve your baseband.

Step 5: Next, it’s time to select the location of your SHSH blobs. If your SHSH blobs aren’t local, you haven’t fetched your blobs, or performed this restore before, you will most likely need to click the Remote option. This will fetch the necessary blobs from Cydia.

Step 6: Once your select your blobs, the restore process should begin, and you will be restored to the firmware you selected. If, however, you receive an error saying Couldn’t restore Mismatched APTicket, then your device will be kicked out of DFU mode, and the restore will halt. Don’t worry. Place your device back into DFU mode, and repeat step 3 again, and the restore should take off from there.

That’s it; that’s all there is to it. This new restore method is leaps and bounds easier than previous downgrade methods. What’s even better is that this downgrade method doesn’t even require you to use iTunes!

MuscleNerd and the iPhone Dev Team truly did the community a huge favor with RedSn0w 0.9.15b1. Its features are downright amazing, as evidenced by this new downgrade method.

    Jeff if I have an iPhone 4 on 5.0.1 is there any way to upgrade to 5.1.1? The phone has never been upgraded pass 5.0.1

    • http://twitter.com/iDara09 Dara

      If your iPhone 4 is currently on 5.0.1 and jailbroken, you should check your Cydia, if there is a stored 5.1.1 blobs, if it is there then you are good to go (Update to iOS 6 then use this above tutorial to downgrade to 5.1.1). ;)

      • http://twitter.com/iPhoneHrvatska iPhone Hrvatska

        If he has 5.1.1 blobs he can go right to 5.1.1, no need for update to 6

      • MAFYOSO

        I don’t have the phone with me currently but is there any way the 5.1.1 blobs would manifest themselves without me ever being on 5.1.1? The iPhone 4 on 5.0.1 is jailbroken but never updated passed 5.0.1 as of yet. Ill check it once I get home but I don’t see why Blobs would be created for 5.1.1 if it was never updated to it. I may be wrong reason Im asking. Thanks

      • http://twitter.com/oneBurge Burge

        You don’t need to go to iOS 6 if he’s got his Blobs and API ticket ..just use tiny umbrella and iTunes ..

    Has anyone noticed with the ported Siri on iPad 3 gsm on 5.1.1
    you don’t have to put in a proxy host url, if the iPad 3 gsm baseband is upgraded
    to the iOS 6.0 baseband? i have two iPad 3 gsm new with shsh blobs jailbroken
    on 5.1.1 and installed on both a ported siri form spite 3.0.2, one iPad 3 gsm got stuck on apple logo, i used new RedSn0w and did the restore and upgraded the baseband to the latest which is the ios 6.0 and reinstalled the ported Siri and when i went to test it out with out putting in any thing no url or certificate siri just works!
    both my iPad 3 gsm are on 5.1.1 one with new baseband and both with the same ported Version of Siri and one just works with out proxy host! thats soooo cool!!
    is its just me! Some one test it out and tell me it’s not just me!

    • hotdog714

    do you have to be jailbroken (tethered) on ios 6 first, to downgrade?

    • http://twitter.com/oneBurge Burge

      No.. Just need to put it in DFU mode

  • http://www.facebook.com/rodel.rufo Rodel Rufo

    I didn’t update to 6, my iPhone is still on 5.0.1. I only want to update to 5.1.1. I will appreciate it if someone guide me how do I go about this using Redsn0w 0.9.15b1?

    • http://twitter.com/samuelayoub Samuel Ayoub

      done the same steps my friend but you have to have your shsh blobs

      • http://twitter.com/oneBurge Burge

        If he’s jailbroke on 5.0.1 then Cydia will have those blobs..
        Use tiny umbrella to get them . Or redsnow

      • http://www.facebook.com/rodel.rufo Rodel Rufo

        I have the blobs and JB on 5.0.1. How can I update to 5.1.1 and then apply JB using the latest version for Redsn0w?

        Thanks o0o, I have already downgraded mine 2 weeks ago… ┌∩┐(◕_◕)┌∩┐.

    • Sam

      Use sn0wbreeze and then use the custom ipsw (baseband preservation) mode to first build the custom ipsw, then use the custom ipsw to restore using redsn0w and when the option comes to preserve baseband select no (even though we select no here, as we are already using a custom ipsw , it will preserve the baseband anyway), and then proceed.

  • padraic dundon

    I have a previously jailbroken iphone 3gs which I upgraded to IOS6 on baseband 5.16.07. Since the upgrade the GPS is no longer working, and I suspect this may be a legacy issue from the original jailbreak. However, other than the GPS, the phone is working fine and some apps (eg Sky Go) now work as the phone is no longer deemed to be jailbroken. Is this a known issue, and if so, what is the solution?

  • mavd@pogs

    use snowbreeze and create a custom ipsw and use that on redsnow 9.15b2 works for me,,also encountered error 2601

    The downgrade worked as far as I can tell but the phone immediately went into recovery mode. How do I fix this without having to restore my phone? I do NOT want to go back to iOS 6! Please help! Thanks!!

  • Khalid

    All, I have found the easy way to Downgrade it back to ios 5.1.1, I had the problem while i was restoring the custom ipsw, the problem was missin keys.plist, so now Just do below things… as stated, you will get ios 5.1.1 back 100%.

    For those like you with missing keys.plist -I was get the same error .Execute redsnow (admin)Go to extrasSelect Custom Ipsw (iPhone3,1_5.1.1_9B206 or 208_Restore)Go to Shsh select Stich and select the Ipsw made custom (xxxxxxxxxxxx_NO_BB_iPhone3,1_5.1.1_9B206 or 298_Restore)and waith to finish and when the program finish the personalized ipsw select local or cydia or remort ..Now you have a No_bb custom ipsw .Put your phone in dfu mode and turn on Itunes .Press shift and restore and select the no_bb ipsw and wait to finish the restore of firmware ..I used this “form” and i have right now the 5.1.1 not the gm6.I hope this will help you guys ! Enjoy :)

  • Kristatos

    Worked like a charm…I first got an error message when the restore
    started…then I just followed the instructions…the phone was with the
    apple logo and and almost empty progress bar (starting the restore
    process)…I just put it back in DFU mode straight from that
    screen…(power button for 3 sec, home and power buttons for 10 sec,
    only power button for 14 sec) and restarted redsn0w…started from step
    three again and it worked fine…thanks a bunch…:)
