Breaking: Downgrades From v1.1.1 Are Possible [Updated with guide]

Submitted by Michael Johnston on September 29, 2007 - 6:54pm.

The clever folks over at the Hackint0sh forums have figured out a way to revert the iPhone's software back from v1.1.1 which came out Thursday. After failing numerous times, Hackint0sh user Kmac1985 figured out the magic method for downgrading. The benefit of this is primarily to fix disabled phones of users who had unlocked them. For the honest folks out there, this also re-enables the use of 3rd party applications. So if the iTunes Store wasn't as sweet as you had hoped, you can now go back in time and enjoy Installer.app all over again.

To downgrade your iPhone to version 1.0.2, follow these instructions. Have the iPhone docked and plugged into your computer with iTunes open:

  1. Hold down the Sleep/Wake and Home buttons at the same time for about 10 seconds. The phone should shut down.
  2. When the phone shuts down, release the Sleep/Wake button but continue holding Home
  3. Wait until iTunes recognizes the iPhone. The screen will appear to be off, but iTunes will eventually recognize the iPhone. When it does, let go.
  4. A message will appear telling you to restore. Click OK
  5. Using your favorite browser, download the v1.0.2 software from this location. You may need to rename to .ipsw if it comes as a .zip
  6. Back in iTunes, hold Option on the Mac or Shift on the PC while clicking Restore. Navigate to the software you downloaded and select it.
  7. The phone will restore, but it will fail. This is normal.
  8. Your iPhone should show a yellow triangle. Run Nullriver's AppTapp. It should bring you back to the Activation step on the phone and show an error in the application. Disregard the error.
  9. Run AppTapp again and it should succeed.
  10. If not using an AT&T SIM, use INdependence to activate your iPhone. That's it!

We have not tried this yet, but there have been at least 50 successful downgrades reported thus far. If you have trouble with these instructions or if we missed something, let us know!

Updated at 8:50 Central: You may also follow the instructions posted by the iPhone Dev Team here.

AT&T service affected?

Submitted by capnken (not verified) on September 29, 2007 - 7:26pm.
Seems to be indications in the hack forum that this trick might leave you with no cell service if you're on AT&T but looking to correct the mistake of getting the 1.1.1 update. Any confirmation either way on what happens to phones with active AT&T service?

success downgrading from 1.1.1 to 1.0.2

Thanks so much to all who are helping defeat the wrong attitudes at Apple.
It's like the old Joni Mitchell song - you don't know what you've got till it's gone.
I missed Summerboard and SendSong and LightsOff and so many others, so now I will be making donations to all of the developers I can find!

re: capnken's question- My AT&T service seems to be working as expected. Well, maybe voice mail is hosed... not sure yet.

Works

works great for me, didnt need to use the unlocker... after 2nd run through apptapp itunes opened and i restored my last sync'd backup of my iphone and it works great.

THANK YOU SO MUCH!

Worked like a charm!

Submitted by astropol on September 29, 2007 - 8:11pm.
Successfully downgraded from 1.1.1 to 1.0.2! Hallelujah!
Easy breezy. Second AppTap install worked. Didn't need to run INdependence. It activated all on it's own. iTunes immediately recognized it and asked me to restore to the last sync. All my settings are exactly as they were. Even prefs and settings from the 3rd party apps like Summerboard and Navizon that I'd had before the 1.1.1 update were restored!
All AT&T services including Edge and voicemail work perfectly.

Thanks to all the dev community. I donated and urge everyone to do the same. Keep them crankin!

and now we wait for the break on 1.1.1

I took the plunge and can confirm all AT&T services are working correctly; 3rd party apps are back, etc. I got an error at the end of the Apptapp process the first time and didn't get installer.app showing up, but I just re-ran it after restoring in iTunes and all is right with the world again.

Kmac1985 for President!

ringtones

Any word on whether or not this will allow us to add back the free custom ringtones we made prior to the firmware update?

Wow, this was a quick workaround. I hope after the break of 1.1.1 is made and Apple releases 2.2.2 or whatever, and Apple gives a warning that patience is exercised as the Developer team finds a workaround in a matter of days... It would certainly relieve one's stress, reduce their blood pressure and reduce the profanity on some of these message boards, okay?

iphone at&t not working

Submitted by *hz357 (not verified) on September 29, 2007 - 9:31pm.
Okay so I can get into the phone, but no at&t services available, what now??

Submitted by Extenet on September 29, 2007 - 9:45pm.
attention all
this is what downgrading to 1.0.2. can do for you

After downgrading firmware to 1.0.2. you can:
Jailbreak/unshackle your phone
(This means iBrickr, and iFuntastic work perfectly )
add all 3rd party apps (via installer,apptapp installer)
add custom ringtones via the way you used prior to 1.1.1
Basically. . . you can do whatever you wanted to do prior to upgrading

HOWEVER
there is still no way to use any other SIM aside from original AT&T. . . however, the dev team is working on a way to get that back together and from what I can see are very hopeful that this can be done and soon.

hope everyone is happy now that we can go back and wait for them to continue breaking the 1.1.1

You Mother F@%#@ it work!!!

You're not supposed to unzip the files. Rename the .zip to .ipsw and restore from that single file.

If you don't have an AT&T account, you're SOL. Do you have AT&T or is it another carrier?

I am trying to downgrade from the 1.1.1 to the 1.0.2 on step 6 it says " Hold option and click restore" Which I did, and I have downloaded the 1, 1_1 as it told me to. The instructions are to then "Navigate to the down load and "Select"" What am I suppose to select? When I navigate to it there are like 4 options and a folder that takes me into another bunch of stuff. Pleas help if you can...

Please help.
It seems that when I download the file it decompresses it automatically to a folder. Is it any other way to do it or I am doing something wrong? I just clicked on the link and after awhile it asked me if I want to download it and I said yes and made a folder on my desktop where I decided to save it. Pls let me know what I am doing wrong.Thanks a lot.

worked great for windows. Thanks so much. The only downside is having numbers and my camera roll deleated in the restore.

Excellent!!

Submitted by danno (not verified) on September 30, 2007 - 7:49am.
Thank you for the post. My phone is restored and working great. I had to run installer more than 2 times - in fact - it kept repeating the error over and over until I launched iTunes and strangely it finally succeeded. I recommend this method to anyone who wants to return to having fun with their phone. Third party apps are FAR BETTER than giving Apple more money by using the wifi store.

hey there. jus wandering about this downgrade. if you buy a new iphone with fw 1.1.1 already intstalled does that mean you can downgrade and then unlock the phone to use any sim card? secondly if you had upgraded the fw to 1.1.1 from 1.0.2 but did not try to unlock the phone previously does that mean you can downgrade to 1.0.2 again and unlock the phone to use any sim card? thirdly if you bricked your phone by upgrading then this will downgrade your phone to 1.0.2 and can use all functions apart from caling unless you have original at&t sim card? chrz

You're supposed to select the .zip file. If you use Safari, it will decompress and put the .zip into the trash. Just drag the file out of the trash and select that.

Submitted by Extenet on September 30, 2007 - 8:40pm.
You're going to have to look into turbosim or something like that in order to get activation if you were not on AT&T. If you were on AT&T retry the downgrade.

been have Incorrect SIM problem; i tried to downgrade from 1.1.1 to 1.0.2... after following all the steps, i got "Bootstrap failed, see Console log!" in AppTapp after selected firmware 1.0.2...HELP

Submitted by ausiphone on October 1, 2007 - 5:19am.
simple....

When you update like i did you flash the baseband of the fone so other sim cards no longer work.

Wot we need is the fantastic people over at anysim to make a new version that can over-write the baseband if u have recievced the update and downgraded. So far this has not been made possible.

Solution is to donate to anysim and wait like im doin. I wish it would come out by the end of the week but im dreaming.

any one tried this update from the dev team??

itunes downgrade

Submitted by *hz357 (not verified) on October 1, 2007 - 4:47pm.
in order to run a older version of itunes you need to delete new one and then move you library else where, so itunes doesnt try to read it..
it should be in username/library/itunes

THIS IS FOR METHOD C

my bad i did that stuff,
and now i opened itunes and it says the iphone only works with a later version of itunes, the stupid part is that i had upgraded to 1.1.1 before opening the new (old 7.3.2) itunes

so im thinking this is a re-downgrade. if you open itunes 7.3.2 after activating your iphone at 1.0.2 then i think you will be able to restore your iphone internet and at&t functions after running apptapp installer like it says in Method C

one more problem though, The version of apptapp they recommend downloading is for itunes version 7.4 and later

i wish someone could just do this for me.

it's getting to confusing.

help if you want

P.S. the current situation is that i'm running 1.0.2 on my iphone it is not bricked, but no internet functions work and it says inncorrect sim card.

those damn instructions arent so helpful

i did right after i downloaded 1.1.1 by mistake and they gave me a sim card without hesitation.
maybe that would work,

AT&T and the FCC

Submitted by nycruza on October 2, 2007 - 10:39am.
As reported elsewhere, the contract with ATT wireless has a section that they must supply an UNLOCK code IF requested after 90 days of usage AND good credit.

Naturally, they cannot comply with their own contract when it comes to an iPhone!

The same article says, write the FCC!

I did and received a personal phone call from the FCC regarding this.
They asked for some additional information about my complaint.

PLEASE!

Take a moment to fill out the FCC complaint form available on the net!

The FCC is taing this seriously and may be the best shot we have to opening the iPhone.
