How to Downgrade iPhone 3.1.3 to 3.1.2

Sebastien, Feb 7, 2010

downgrade iphone 3.1.3 to 3.1.2

As always when a new firmware is being realeased, there is always a few unlucky people who “accidentally” update or restore to the latest firmware, thus losing their jailbreak and unlock.

In this case, you’d usually want to downgrade your iPhone from 3.1.3 to 3.1.2 simply by downloading 3.1.2 and SHIFT + Restore in iTunes so that you can choose your own firmware to restore to.

The problem is that Apple recently stopped signing all previous firmware versions making it impossible for you to downgrade.

Fortunately, Saurik has been smart enough to create a system to bypass Apple’s signature and making it possible for you to downgrade from 3.1.3 to 3.1.2. To do so, you will need to have your SHSH on file. To see if it’s on file, launch Cydia and look at the top. Mine says “This device has SHSHs on file for iPhone OS: 3.0, 3.1, 3.1.2″.

If you don’t have this, make sure you look for a link that says “Make my life easier” on Cydia. This will allow you to save your SHSHs.

This being said, downgrading an iPhone 3GS from 3.1.3 to 3.1.2 is easier said than done. It’s actually a pretty painful process that I detailed in a tutorial a few month ago. I originally wrote this tutorial to downgrade from iPhone 3.1 to 3.0 but the steps are exactly identical (MuscleNerd confirmed this).

If you’re one of those who need to downgrade your iPhone firmware, then check out my tutorial, or simply wait for the Dev Team to come up with a reliable jailbreak for 3.1.3. Something tells me PwnageTool is not too far ahead of us ;)

UPDATE: If you have an iPhone 3G, you can now downgrade from baseband 05.12.01 to o4.26.08.

UPDATE 2: This post is slightly outdated. Check out this page for the latest information about downgrading your iPhone.

    Help!!!! I accidentally upgraded my iphone 3GS to version 3.1.3. I’ve follow the steps and i got error 1600. Please help!!!!!

  • Boogyman

    I was able to successfully jailbreak my phone that was previously updated to 3.1.3. After hours of trying blackrain and snow. I installed a 3.1.2 firmware version with an 10.15 error. Installed blackrain after ignoring the error and noticed everything worked but my att wireless signal. Clicked the blackrain icon on the phone and installed cydia to help ensure the phone was unlocked then I used Snowbreeze to upgrade the firmware to 3.1.3 and viola everything worked including my Att wireless signal. Hope this helps those of you who are using 3.1.3 and want to jailbreak your phone. You can’t jailbreak your 3.1.3 unless it has been broken in 3.1.2…very important.

  • Stasia

    I tried to downgrade to 3.1.2 but it didn’t work and now the phone is stuck in DFU mode – I can’t get to it to turn on anything.
    Does anyone haveany suggestions as to how to get it out of this mode?

  • Nelson

    I Successfully downgraded to 3.1.2 from 3.1.3 without having an SHSH or whatever on file. Will tell via email hopefully it will work for you aswell. Lockdown09@yahoo.com

    For those who have an apple product like iPhone3GS, iPhone 3G, Ipod touch, Ipad. There is a simple way to downgrade any firmware on your phone/ipod. All you do is go to apple.com go to iphone and download there SDK development software for 3.0 or something 3.1 whatever it is its the iphone SDK then run the simulation and Xcode as you have your iphone plugged in then downgrade the firmware that way. fucking noobs.

  • Callen

    Hi,

    I had my shsh saved on Cydia. I just successfully downgraded my 3gs 3.1.3 on 5.12.01 (Old Bootrom) Its now 3.1.2 and obviously the baseband is still 5.12.01. I can jailbreak it with Blackra1n, I have full reception & I can make phone calls fine. The ‘3G’ logo is on the top bar yet I cant get the internet other than Wi-Fi. Is this supposed to be the end result or am I missing something. Is there something on Cydia that can rectify this.

    Thanks – Please let me know

  • littledaemon

    @Callen

    Do you see any sort of error when you try to use the internet without WiFi?
    Very likely your data profile is screwed up. I suggest you goto this website :
    http://www.iphonedownloadblog.com/2009/08/29/could-not-activate-cellular-data-network-you-are-not-subscribed-to-a-cellular-data-service/

    Read the instructions, generate a profile for your provider and install it. In my view, that should get you running.

  • Callen

    Thanks littledaemon, but re-installing and trying a few other things, the thing that worked was to simply Reset Network Settings.
    I think I synced with itunes after the jailbreak and that gave me my old and incorrect network settings or something.
    Finally, I have a Cydia on a 3gs downgrade with a 5.12.01 bootrom.
    Thanks anyway mate

  • resgoal

    Hi Everyone,

    For whatever reason you want to downgrade iPhone firmware, follow the instruction from this guy here http://www.iphonedownloadblog.com/2009/09/15/downgrade-iphone-31-to-30/. Even though this guy is made for downgrading from iphone 3.1 to 3.0, it doesn’t matter. At the step where they asked you to select the firmware, just use the firmware for 3.1 or 3.0 or whatever firmware you want. Have fun.

  • friedgidier

    if you upgraded to 3.1.3, there is a new jailbreak that is untethered, you may want to check http://spiritjb.com/

  • S

    Hey, I am using iPhone 3G with 3.1.3 and jailbreak using spirit. I don’t have a SHSH backup, I just can’t see “make my life easier” in cydia, really wonder why. So, is it possible to downgrade to 3.1.2 or older?

  • william

    Only the 3Gs needs the SHSH to be stored on file

  • DKindaFLESH

    I downgraded my iPhone 3G by restoring it with iTunes from 3.1.3 to 3.1.2 on Windows. Shift & click restore. Select 3.1.2 and restore. You should get the 1015 error. This is easy to fix. Your iPhone should be at the emergency call screen. Go to google and google blackra1n and go to blackra1n.com. Save the file to your desktop. Now google blackbreeze. Go to redmondpie.com and look for the link to download. Save it to your desktop and use blackbreeze on blackra1n. Connect your iPhone and run blackra1n. This will activate your phone.

  • DKindaFLESH

    If you only need to jailbreak, use Spirit. That is easy and fast.

  • DKindaFLESH

    To use spirit, your phone must be activated.

  • bishu

    i am having problem in maps. It can’t find my current location. my firm ware is 3.1.2 and its jailbroken. Please help??????????????

  • DKindaFLESH

    I’m not really sure you can do anything to fix current location. Make sure it is not restricted or off. If it is neither of these, it could be a hardware problem with the gps chip in your phone or the firmware is messed up. If possible, just restore to 3.1.3 or 3.1.2 and jailbreak with spirit or blackra1n.

  • Blader

    Hi guys! I have 2 iphones (one 3G with 3.1.2) and a 3gs with 3.1.3. I want to downgrade the 3gs one…I know that I have to save shsh. Can I use the SHSH that Ive created with 3G iphone to downgrade the other one? Please HELP ME!!

  • Danny

    Your ssh is in sync with the serial number of your phone. So you can’t use it on a different phone beacuse the serial number is different.

  • Terry

    My iphone has this “This device has SHSHs on file for iPhone OS: 3.0, 3.1, 3.1.2″. but it says 3.1.3
