Firmware update 2.2 surprised a few people who accidentally updated their iPhone. If that happened to you, you now have 2 choices: either stay and 2.2 and wait for the Dev Team to come up with a jailbreak method for 2.2, or you can try to downgrade from 2.2 to 2.1.

I personally don’t have this issue. I haven’t updated to 2.2 but I figured that some of you guys may have, so I started looking for a solution to post here. The problem is there doesn’t seem to be a solution that works for one main reason: 2.2 updates your baseband and once your baseband is updated, you can’t downgrade it to 2.1 (not as yet anyway).

From what I read, only 2-3 people were actually able to get their iPhone back to 2.1 without issues but it is very unclear what they did exactly… Now let’s have a look at these different methods that supposedly show you how to downgrade from iPhone firmware 2.2 to 2.1.

Note that I haven’t tried this and I do not approve it. If you choose to try any of these methods, understand that you’re doing it at your own risks. If I were you, I would just wait for a new jailbreak method by the Dev Team.

I found the first method on and here is how it goes:

For downgrading iPhone Firmware 2.2 to an earlier version you will need to downgrade the baseband and firmware, for this following software are needed:

  1. ZiPhone patched by kIREmK (Pls. read this comment).
  2. QuickPwn v 2.1.
  3. Apple iTunes.
  4. Firmware IPSW file : 2.1 firmware 3G or 2.1 firmware 2G.

Once you have got all the above softwares, follow the process below:

  1. Use Ziphone to downgrade the baseband using the settings as shown below.
  2. Downgrade iPhone Firmware
  3. Now restore the firmware to an earlier version using the IPSW file via iTunes, if you receive errors during this procedure simply ignore and proceed further.
  4. iPhone Update Error 1013
  5. Now, use Quickpwn to unlock and jailbreak using the same firmware flash file used to restore in previous step.
  6. Your iPhone should be jailborken and unlocked now.

Please read the comments on MegaLeecher and you’ll see for yourself that it is not a really safe way to downgrade…

Now the second method that I found on

First you need to download iPhone firmware 2.1 (for 1st iPhone, use this download link and for iPhone 3G, use this download link).

You can then follow these steps to downgrade from iPhone firmware 2.2 to firmware 2.1:

  • Connect your iPhone to your Mac or PC select your iPhone from the list of devices in iTunes. If things had gone horribly wrong while hacking your iPhone and iTunes does not detect your iPhone then you will need to put it in DFU (Device Firmware Upgrade) mode.
    • You can follow these steps to put your iPhone in DFU mode (this is required only if iTunes does not recognize your iPhone):
      • Connect your iPhone to your computer.
      • Turn iPhone off.
      • Hold power and home together for 10 seconds (exactly).
      • Release power but keep holding home until the computers beeps (observed on a PC) as a USB device is recognized.
      • A few seconds later iTunes should detect your iPhone.
  • In the Summary Tab, Hold down Option and press the “Restore” button. If you are using Windows hold down Shift and press the Restore button. (This is an important step as just pressing the “Restore” button will result in restoring your iPhone with the latest firmware which is firmware 2.2 currently, by holding down Option in case of Mac or Shift in case of Windows, allows you choose the firmware file that you want to downgrade to.)
  • Restore or Revirginize iPhone

  • You should be able to see all the older iPhone firmware files you had downloaded so far, select iPhone firmware 2.1 file (iPhone1,1_2.1_5F136_Restore.ipsw) to restore your iPhone or browse to the folder where you have downloaded it and select it.
  • You might get the any of the following errors: 1011, 1013, 1015, you can ignore them. However, if you get errors such as: 1601, 1602, 1600 or anything else then try putting the iPhone into DFU mode and try again.
  • Your iPhone should now be restored to iPhone firmware 2.1 (Settings -> General -> About). You can then jailbreak and unlock your 1st gen iPhone or jailbreak iPhone 3G.

Again, I highly suggest that you read the comments about this method…

If you have successfully downgraded your iPhone from 2.2 to 2.1, please let us know how you did that.

    I have iphone 3g 2.2 , to solve the no service problem I purchased rebel simcard from uk, I did updating for the simcard to v54i ,And I followed the instruction as shown in the video in rebel web site , but still giving me no service.

  • Anndrew

    Works like a charm. Downgraded from iPhone 3G v.2.2 – v.2.1 🙂

  • Chirag

    As i said restoration is possible but downgrading of baseband is 99% not possibe…
    1% possibility is thr…
    The solution is to use turbo sim for 2.2 ……
    as per i am selling it in India (New Delhi)..

  • Ill make this some what easy for you guys. I think I’m the only one that knows this. Theres a problem with the turbo sims on resetting network key issue. For you guys running 2.28.00 firmware any turbo sim will work. The temporary problem solver for the no service issue is to take your tmobile sim (In my case) out of the iphoneand put it a regular tmobile phone and use it, you know make a couple calls to a friend and cust. service. RESTART IPHONE> Then take that same tmobile sim and put it back in the iphone, after boot you will see no sim installed. Then insert sim back into the iphone and wham you’ll have service. The only downfall is that you’ll have to do this every 3-5 days. But hey beats being stuck with a 500 dollar ipod or storing it on a shelf. Never use the turbo sim with nothing but the iphone. Only use the actual sim card when reactivating network keys. Good luck guys, and for some of those responding please read what the thread is about. TIM

    It work ! Thx. It’s verry sample. All you have to do is downloading the bootloaders, open the ziphone, make what they say, then open QuicPWN, and there are 5-6 steps.

    My 2G iPod had not been jailbreaked, but needed a 2.1 device for testing purposes and had no issues. I merely opened up iTunes 7.7 on my Mac, did the Control + Restore and chose the 5F137 version. After update it said I needed to udpate to iTunes 8.0, but once I did that, it worked fine.

    Hey guys I found a solution for the 1013 error problem while downgrading the 3G from 2.2 to 2.1. after getting the 1013 Error notice click ok and download Quickpwn2.2(windows):
    run the software once the pop up appears unplug the phone and carry out the instructions. This will reboot your phone in 2.1 then u can screw it up again.

    hi. how can a 2.2.1 be unlocked???

  • Ed

    MANAGED to make WiFi work on 2.2.1! I know how strange it may sound, but I tried all the ways described in here and noone seemed to work. First, I tried to restore from iTunes (did not even know there are issues – thought it may have been my phone error). Issue was there. Started to read posts. OK. They told – downgrade to 2.2. Did that. Easy way – Shift + Restore in iTunes. Did not work. Downloaded 2.1 firmware. Downgraded easy way. Shift + Restore 2.1. Did not work. Then tried to downrade basebang with ziphone. Ran bat file. Phone went to restore mode and nothing happened. Well I was fed up and decided not to try anything else. Then simply went to iTunes. Upgraded iPhone to 2.2.1. And all seemed to work. Tried to restart – WiFi went on after reboot. Then tried reset with BossPrefs. Again WifiWent on. Tried to diable WiFi and enable in Settings (previously it did not work) – worked without any issues. I have no idea how it all just started to work, but perhaps it was something with the downgrade sequences that just worked by incident. have no idea. But Wifi is ON and running as before.
