How To: Downgrade iOS 5.1 To iOS 5.0.1/5.0 On iPhone 4/3GS, iPad 1G, iPod Touch 4G/3G

Apple released the iOS 5.1 firmware update right after they announced the new iPad and the Apple TV 3G on March 7th. Although we warned Jailbreakers to stay away from the iOS 5.1 firmware update, I am sure there are some people who have accidentally upgraded to iOS 5.1.

Now the reason why accidentally upgrading to the iOS 5.1 firmware is a big deal, is because only the iOS 5.0.1 firmware can be Jailbroken Untethered at this time. This means if you upgraded you will only be able to Jailbreak tethered, or worse, even not at all for those who upgraded their iPhone 4S or iPad 2.

If you are looking for a how to guide on how to downgrade your iPhone, iPod Touch or iPad from the iOS 5.1 firmware to the iOS 5.0.1 or iOS 5.0 firmware then you are in luck! In this how to guide from you will learn how to downgrade your A4 iOS device to the iOS 5.0.1 or iOS 5.0 firmware from iOS 5.1. Before we start however make sure you meet the requirements listed below…

iOS 5.1 Downgrade Requirements: 

  • Supported iOS devices include the iPhone 4, iPhone 3GS, iPad 1G, iPod Touch 4G, iPod Touch 3G. Unsupported iOS devices include the iPhone 4S, and iPad 2.
  • APTicket + saved SHSH blobs for the iOS 5.0.1 or iOS 5.0 firmware.
  • A Windows computer.

Downgrade From iOS 5.1 To iOS 5.0.1 / iOS 5.0

Step 1) – The first thing you will need to do is download a tool developed by iH8Sn0w called iFaith. What the iFaith tool does is dumps the SHSH blobs directly off your iPhone, iPod Touch or iPad for the firmware you are currently running. Allowing you to stitch together a custom firmware that can downgrade your iOS device to a previous firmware version Apple is not signing. If you are following this how to guide you most likely already used this tool to dump your iOS 5.0.1 or iOS 5.0 SHSH blobs.

Download iFaith 1.4.2 (Windows)

Step 2) – The next thing you will need to do is run iFaith (click the OK button once you have read the warning).

iFaith v1.4.2 Windows

Step 3) – With iFaith up and running you will need to click the Build *signed* IPSW w/ Blobs button.

iFaith v1.4.2 Windows

Step 4) – Upon clicking the button previously mentioned you will need to browse for the saved SHSH blobs file that was created when you saved your SHSH blobs for the iOS 5.0.1 or iOS 5.0 firmware.

iFaith v1.4.2 Windows

Step 5) – It is now time to browse for the iOS 5.0.1 or iOS 5.0 firmware file. Depending on which SHSH blob file you selected you will need to select either the iOS 5.0.1 firmware file or iOS 5.0 firmware file (download iOS firmware files here).

iFaith v1.4.2 Windows

Step 6) – After you have selected the right firmware file iFaith will begin creating your custom firmware file.

Step 7) – When your custom firmware file has been created go back to the iFaith main menu (if you are not there already) and click the Use DFU Pwner (iREB) button. Now simply follow the instructions presented to you for putting your iPhone, iPod Touch or iPad into pwned DFU mode.

iFaith v1.4.2 Windows

Step 8 ) – With your iOS device in pwned DFU mode you will need to launch iTunes and restore your iPhone, iPod Touch or iPad to the custom firmware file you created. This can be done by Option (alt) clicking the Restore button on Mac OS X or by SHIFT clicking the Restore button on Windows.

Congratulations! You have now downgraded your A4 iOS device from the iOS 5.1 firmware to either the iOS 5.0.1 firmware or the iOS 5.0 firmware. If you have any further questions or concerns please leave them in the comments section below…

  • d_nil

    Worked for me as well. I used this guide to actually upgrade from iOS 4.3.3 to iOS 5.0.1. before this I kept getting error 3194 “This device isn’t eligible for the requested build.”. this was due to Apple has stopped signing iOS 5.0.1 I think. custom firmware I buld with sn0wBreeze didn’t restore either but this guid worked great. thanks very much

    you can´t downgrade to a older version like 5.0.1
    you have to wait for a jailbreak on 5.1

  • Luke Harris

    I managed this..

    iPhone 4 (GSM)

    Upgraded from 4.3.3 JB to 5.1non-JB through iTunes.
    Used TinyUmbrella to grab my previous SHSH Blobs from 4.3.3 (I had never used/backed up these prior to upgrading to 5.1 so I was lucky to grab them).
    Used iFaith as outlined above with SHSH Blobs from TinyUmbrella, and let iFaith download the 4.3.3 FW to downgrade.

    (I had the options of 4.3.3 / 4.3.4 / 4.3.5 / 5.01 when using TinyUmbrella to grab the blobs.)

    hope this works for some others! (-:

  • Shutrs

    Dík moc byl to boj, ale úspěch se dostavil.. ĎĎĎ

  • op3d

    does it preserve the baseband? or it will upgraded the baseband? coz i rely on ultrasn0w to unlock my 3GS. if it upgraded, i cant unlock with ultrasnow :(

  • bhmiji077

     i thought that too. if you had cydia before, the download tiny umbrella and click there “save SHSH” (something like that) then it will show you all your shsh blobs. if you didn’t had cydia ever, then you’re screwed

  • TG

    Downgrading from 5.1 to 5.x, also works using redsnow, if you’re on a mac.  (provided you’ve saved shsh blobs and APticket.)  Just open redsnow, and stitch a 5.0.1 firmware with your shsh blobs and APticket that you saved.
    Then open redsnow again, and get into pwned DFU mode.  Option-click restore in iTunes, and select your custom firmware you just created.
    Let it do its thing, and at the end most likely you will get: “error 1, this iphone could not be restored, an unknown error occured.”  When that happens, open redsnow and click “fix recovery” and follow the directions (it will tell you to enter DFU mode again” then it will exploit with limerain, and when its done, you will be on 5.0.1!
    No tinyumbrella, or ifaith needed.  Redsnow and iTunes are all you need.

  • Mugy7

    Hi guys, need some help
    Ive made the custom firmware and put my iPhone 4 into pwned DFU mode, but whenever i shift-restore, the restore progress bar gets to the end and then iTunes throws an error 37.
    This has happened twice and afterwwards my iPhone appears to be bricked.
    Forced restart doesn’t work, the only way to fix this is to restore to iOS 5.1
    Anyone else have this problem and does anyone have a solution to this?


  • Cesar

    Hey guys, I currently have my iphone 4 jailbroken on ios 5.01, it entered a recovery/respring loop and it’s been impossible to fix (I’ve mainly been trying to shift+restore the 5.0.1 custom IPSW I saved when I jailbroke it, but I keep getting itunes errors). I’ve been thinking maybe I should re-jailbrake to 5.1 and then downgrade back, however I HAVE NOT backed up the blobs on my computer (they are on Cydia but since I’m in the recovery loop I can’t get them). If I run tiny umbrella in it’s current state, the iphone (and blobs) doesn’t show up, I’m wondering if I upgrade, re-jailbreak in 5.1, and THEN run Tiny Umbrella, will the old blobs show up? I’m thinking they should as I’ve had Cydia for over a year, but I don’t want to mess up and end up with a tethered jailbreak I can’t get out of… Any suggestions? Thanks!!!

    Thanks so much this method worked great!

  • vazzkii12

    So guys I also had some problems downgrading my iTouch 4 from 5.1 to 5.0.1, but still I managed to fix it now: SHSH Blobs are necessary, so use a shsh blob from another iTouch with iOS 5.0.1 and save it using TinyUmbrella, then use iFaith to search the file and follow the instructions above. Without shsh blobs you can’t downgrade it :/ or jailbreak the iOS 5.1 and save your shsh blobs when cydia is installed, again use the instructions from above! Hope this helps.

    Hi, it doesn’t work for me.

    Hello iJailbreak

    I have downloaded to iOs 5.1 not knowing it is an iOs which dosent have jailbreaking options on it. I am planning to use your method but I want to know 100% that it is completely safe, and will not cause any viruses as I will be extremely mad and stressed out if it will do anything unusual to my computer. I have all of the listed things and am ready to do your method though the health and safety conditions must be good. Please answer back soon

  • CideoHelper

    Surprisengly I was on 5.0.1 and had accidentally removed cydia. I did not have iFile or OpenSSH installed. That meant I was doomed. I tried to save my shh blobs and the first I got nothing. The next time I tried I got SHSH blobs for 4.3.3/4.2.5 and 5.0.1 !! What Luck! I am currently downloading 5.1 and purposely upgrading to re-jailbreak my iPod after I downgrade from 5.1 to 5.0.1 !!! Thank you god!

  • ziafm

    its possible to downgrade iphone 4s 5.1 to 5.0 firm ware

  • Greg


  • Greg

    It should have worked though, but glad your back online

  • Greg

    you either get them when your signed or you don’t get them at all, simple as that, (have to get them when the firmware is fresh and live) not when its stopped being signed by apple

  • Greg

    did you preserve your baseband before you upgraded to 5.0.1? if you didn’t your SOL because 5.0.1 be default upgrades your baseband

  • Greg

    he followed the instruction? this is a off basis question

  • GREG


  • Greg

    perhaps follow the instructions posted by ifaith?

  • Greg

    you can grab them with tinyumbrella if you had them in cydia saved at the top for 5.0.1 or 5.0, once you have the blob itself used ifaith to create your custom ipsw to restore from,  (this is important if your only at 5.1 because you upgraded but jailbroke and saved your SHSH blobs with cydia)

  • Greg

    same here, thanks for your reply, made me feel good and secure to do it myself too

  • Greg

    where your shsh’s files used? where they perhaps corrupted?

  • Greg

    nope your SOL until 5.1 jailbreak untethered comes out, sorry man

  • Greg

    no they are serial number specific, each have a different serial numbers attached to them, sorry man your sol

  • Greg

    if you want to save it too you have to also make a file that will save your BB as well, I believe you had to run it through redsnow first then stich your ipsw file with ifaith to restore, (google it I recall seeing a method for you)

  • Greg

    NOOOOOOOO PLEASE UNDERSTAND AND WAIT, you should have heeded the warning before

  • Greg

    perhaps bad SHSH’s files?

  • Greg

    you could always download it standalone and then browse for it, google the firmware file you need for your device 

  • Greg

     glad to hear, just like me, although I got it on the first try :)

  • Greg

    NOOOOOOOOOOOOOOOOOOOOOOOO, stop asking read the article before posting 

  • Greg

    bad SHSH for sure

  • Greg

    your shsh’s files may be bad, try downloading them again, from tiny umbrella instead 

  • Greg

    from tinyumbrella, google a tutorial for it, it will walk you through it

  • Greg

    you should most likely get 5.0.1 or 5.0 for your device as a standalone ipsw file, google iphone firmware and download it for your device then browse instead of download in Ifaith

  • Greg

    you SOL , please understand your going to have to wait till a 5.1 jailbreak thats untethered comes out, sorry man

  • Greg

    thanks, great to hear, same like me success on Iphone 4, without issue on the first try!

  • Greg

    great to hear your back up and running! I did my iphone 4 without issue, even on the first try. 

  • Greg

     yes its safe, just have to do everything to a T! I did my iphone 4 without issue, you should be good :) as long as you have your SHSH’s for 5.0.1 saved for your device I can’t see an issue

  • Greg

    no your good to go, grab them with tinyumbrella, once you have them from there you can cook up your own custom firmware with this guide at the top of the page, as long as you have an iphone 4 like you say you do, then your good to go, as well you actually saved your SHSH’s to cydia’s servers 

  • Greg

     it is already out but it depends on the device itself

  • Greg

     bad ipsw file, download from a different sorce,

  • Greg

     you downloaded a bad IPSW file, redownload it from somewhere else and try again

  • Greg

    read the above comment

  • Greg

    someone who knows that they are talking about for once, congrats!

  • Greg

    which device did you restore (others might be wondering like me)

  • Greg

    hold shift and select your custom IPSW (thats provided you followed the steps above and have your SHSH’s files for your device)

  • Greg

    why not grab them from cydia servers via a tool called tinyumbrella, google it and it will tell you how to do it, simple then you can come back and use this method to restore :)

  • Greg

    read the above post

  • Greg

    bad shsh’s blobs sure you got them for your device?

  • Greg

    you have to rejailbreak son with redsnow, this only restores you to the stock 5.0 or 5.0.1 firmware without the jailbreak, once you jailbreak you will have cydia back, simple

  • Greg

    OMG your SOL if you didn’t save them tired of writing this!

  • Greg

    NOOOOOOO your SOL please understand, your going to have to wait

  • Greg

    did you make your IPSW file with Ifaith? did you even read this guide or did you scroll down and just skim through it, I am not typing any further here

  • Greg

    which device did you do?

  • Greg

    yes it will, save everything and then do this method, good luck

  • Greg

    have to cook up a custom ipsw with rednow  no_BB to restore, then use ifaith for the rest

  • Greg

    check if your device has any with tiny umbrella 

  • Greg

    on what device?

  • Greg

    on what device?

  • Greg

    nothing your SOL, unless it showed in cydia that you had 5.0.1 at the top your screwed, if you had in the top of cydia then you can grab them with tiny umbrella 

  • Greg

    put the device into DFU mode, do a google search for the method

  • Greg

    why not re-jailbreak with redsnow? and be back up and jailbroken???

  • Greg

    NOOOOOOOOOO your SOL without them if you had them at the top of cydia saying 5.0 or 5.0.1 then you can grab them from cydia with tiny umbrella then use this guide to restore :) hope that helps

  • Greg

    congrats on what device though?

  • Greg

    on what device sir?

  • Greg

    what device did you restore so other readers know?

    on what device did you do?

    So I want to downgrade from iOS 5.1 to 5.0.1 because I wanna jailbreak my iPod Touch 4G and there isn’t a untethered version yet for iOS 5.1 ( as far as I know) and I was wondering if this would work, downgrading then jailbreaking. Also can someone as kind as to tell me if there is any risks (I will backup my iPod to discs beforehand)

  • DKD5291986

    If you are on 5.1 do a tethered jailbreak download ishshit from cydia select iOS 5.0.1 then check cydia then hit save. I never saved my blobs and some how they just magically appeared after when I used this method and I have now successfully downgraded back to 5.0.1. If this works for anyone else would love the feed back! Good luck!

  • DKD5291986

    Apple is still signing iOS 4.1 you can downgrade to it with out the blobs.

    Dumb Question?
    I have my SHSH blobs but no aptickets for 4.3.5 or 4.3.3
    I have tried to down grade using this method but It seems to only be good for downgrading software, not baseband…
    can I downgrade baseband without apticket?

  • NinjaSkittles

    Are SHSH blobs already on my computer or did i have to save them when i had the 5.0.1?

  • That1GuyWhoHelpsPeople

    like the guide says, you need a windows computer. There is no way (until iFaith comes out with a Mac Version) to do this with a Mac.
    …I know. Sucks to be a Mac user.

  • That1GuyWhoHelpsPeople

    For a guy who helps people… I seem to need some help.
    It’s kind of a beginners question, it’s more me just making sure if I can do this or not.
    Anyways, on to my question.

    If I have a Tethered Jailbreak, the SHSH blobs will still be there, right?
    Or do I still have to wait for the Untethered Jailbreak?

    anyways, to whoever helps me, iJailbreak or just a random person, thanks in advanced.

  • Henrique Iamauti

  • Ajohnson23

    I tryed this, worked fine. Untill I realised that my phone had completly reset and gone too a factory setting, so I tryed too restore my data ‘ie pictures, contacts, notes..etc’ and when I don’t this it came up with an error code, even when trying too re-update my phone too get back too the new software the error code came back up. I hade too plug my phone into a different computer reset it via that computer, then plug it back into mine.
    For all that hassle it’s not worth it, unless there is a way around this then I would bother doing it. Just wait for the jailbreak too come for iOS 5.1 and 5.1.1

  • Thisisthewrongone

    If I download an earlier version of iTunes, can I just download an earlier iOS version on my 3gs? I seem to remember that iTunes now doesn’t allow that, but earlier versions did. Am I correct in thinking that, because if so I would like to think that I can just downgrade the 3gs to an early iOS version(i.e. 4.2.1) and then do an easier method of jailbreaking and unlocking?
