Looks like the iPhone 1.1.1 update is reversible after all (kinda)

Tags: downgrade, firmware, iphone
Alright! Congrats to Kmac1985 from the Hackint0sh forums who discovered this little doozy of a method. Make sure to read the issues below (it's not COMPLETELY reversible). On a phone that has 1.1.1 installed:

- Start by downloading the 1.0.2 firmware here. Get it while it's still hot. That's an Apple download link so it's subject to change.

- Try to sit under a good light source. You need to see the screen clearly when it's not backlit.

- Make sure the phone is on and running normally (if activated, at the Home screen, if not, just at the "Activate iphone" screen). The phone must also be docked or plugged in to your USB cable.

- Press and hold the Power and Home buttons on the phone until the screen shuts off.

- Release the Power button immediately. Keep pressing the Home button.

- You should see a number of horizontal lines invade the now-off screen, and it will be slightly disturbing. If you just see just flat blackness turn your phone back on and try again.

- Your computer will recognize an "Apple Restore (DFU) Device". Open iTunes and it will complain about needing to restore.

- Hold Shift if on Windows, or Option/Alt if on Mac, and click Restore in iTunes. Select the 1.0.2 firmware file you downloaded.

- Let it restore. It will error out but the phone will have been upgraded.

- Restart your phone with the power + home buttons and you have a 1.0.2 phone again! Activate and use according to your preference.

Issues with this method

On my phone the phone won't boot unless I directly issue an "fsboot" command to the bootloader. I don't think this happens to everyone, and it's fixable with a few tweaks to NVRAM (details to come).

Also my phone was unlocked (needle method) and so the radio is corrupt, giving me the "Mismatched IMEI" state that I don't understand very well. Apparently non-unlocked phones suffer this issue after downgrading as well.

If your iPhone just boots to "Please connect to iTunes" all the time

This is an issue that I had. What you need to do depends on your operating system.

Windows:
- Download iBrickr and extract it somewhere.
- Open a command line and cd to the folder you extracted iBrickr to.
- Run iphoneinterface from the command line.
- You should see an r_recovery prompt.
- Type "setenv auto-boot true" and hit enter.
- Type "saveenv" and hit enter.
- Type "fsboot" and hit enter.
- Your phone will boot properly.

Mac:
- Download iPHUC and run it.
- You should get a recovery mode prompt.
- Type "cmd setenv auto-boot true" and hit enter.
- Type "cmd saveenv" and hit enter.
- Type "cmd fsboot" and hit enter.
- Your phone will boot properly.

w0ot, kudos to Kmac1985!

Tried this. All happened as stated, but still the incorrect sim error message! Thank you to all for your hard work!

Re: the "mismatched IMEI"...

I read in some comments on Macworld that the IMEI gets changed internally on your phone to 00499901064000 if it's been unlocked during the 1.1.1 firmware update. Compare the IMEI engraved on the back of your phone to what is displayed in the settings. If they're different, it may be possible with a jailbreak to modify the IMEI back to the original one...

FYI - I never unlocked my phone. I did install the app.Installer before the latest upgrade, but removed it (some app froze my phone so I did a restore and left it in "factory" state) before I upgraded.

Hope this helps!

GOOD JOB! It really works! But are we really gonna have to type in the things into iphoneinterface all the time? Or is it suppose to be a one time thing? because EVERYTIME i plug in my phone, it keeps doing the Connect to iphone thing and i type the stuff in and it works again, but do we have to do this all the time? or is there just something wrong with my iphone? And also are you going to find a better way to downgrade?

I had the "Please connect to iTunes" yellow triangle after downgrading to 1.0.2 from 1.1.1, and using the iphoneinterface instructions above helped me get past that. I still have the "Incorrect SIM" error so still cannot use my iPhone for anything though.

Posted by najah 5 years ago ( 30-Sep-2007 08:33:58 )

can some body tell me how to restore the factory settings in an i phone. there is an icon of a lock, and i was told by the shop it has been already unlocked..but it never works...i tried the ibrickr and nothing happens. so thought of restoring it to 1.0.2(factory settings) following the above instructions, using itunes. but :-( i could not load the older version....waiting to see a kind of magic..

Posted by satan 5 years ago ( 30-Sep-2007 12:07:03 )

After I downgraded from 1.1.1 (i was an idiot and thought I was safe) I had the "Incorrect SIM" message. I unlocked it, using third party aps, but I cant get the phone feature to work.

I tried anySIM but it said my phone was already patched. Anyway I can't get it to work as a phone, but everything else is working.

thanks for all the hard work nate

** To help those who are getting the please connect to iTunes message you have to read all the instructions.

Hey, quick question, I have two iphones and theyre both locked in the sense that im using AT&T but I did indeed jailbreak both phones and have some third party apps installed and a couple of ringtones. Now I guess im not safe to upgrade to 1.1.1 but I was wondering if deleted all the apps and sent my phone back to jail if i was safe to upgrade to the new firmware? Also how exactly would a windows user send his iphone back to jail? Ive only been able to find methods for mac users. Thanks for the help

I'm having the same issue as David every time i power the phone off I'm back in yellow triangle loop.

Questions: 1.1.1 downgraded to 1.0.2 with 00499xxxx IMEI

A.) IMEI 00499901064000 - Without SIM I seem to retain my correct IMEI... but install my old SIM it reverts back to the 00499xxxxxxxxx.
Does this mean I can install a new AT&T SIM and have my original IMEI or am I still in the dog house! (I just want my AT&T service to work... I am missing calls!)

B.) Running Virgin restore - the command "launchctl unload -w /System/Library/LaunchDaemons/com.apple.CommCenter.plist" results in process not found! Does this mean that I have hidden issues to be concerned about? (bbupdate hanges on *.eep since my modem is now 4 instead of 3)

C.) If I ran the Virgin State with the above errors in "B" and then restored the 1.1.1 firmware with the new SIM... Would this put me back to square one or will it be as though I just bought a brand new phone... keeping in mind that I just want to get may phone service back !

D.) Goal here is to restore phone to factory status or either 1.1.1 or 1.0.2 which ever is easiest. Concerns are not the APPS or hacks at this time... but restoring to factory defaults so that I can use the service to the fullest - my service is AT&T!

Thanks

Hey Nate,

Great work on the iPhone you've been doing.

I'm a total noob at this. I'm in Canada but heading to Boston tomorrow for a conference and plan on purchasing an iPhone. Hopefully i'll get one with the 1.02 firmware, but at least now I can downgrade to that from 1.1.1.

I'm not planning to unlock and use it as a phone right away; rather i'll use it for the wi-fi and 3rd party apps.

I'm confused about what I do with the phone to get it up and running once I take it out of the box.

1. Do I need to insert/use the SIM that comes with the phone in order to activate it and/or update/downgrade the firmware?

2. Obviously I don't want to activate it via AT&T. First, do I need to activate the phone before I update/downgrade the firmware to v.1.02 ? If not, does installing and running iBricker "spoof" the activation process? If not iBricker, what software would I use (I have an XP laptop at work and a Mac Mini G4 at home)?

Many thanks!

-Craig

This "Apple has the right to insist that its phone be used in strict accordance with its terms or it can legally damage the phone" mindset is really perverse and, in my opinion, out-and-out illegal: it is like BMW saying that "if you dare put non-BMW tires or windshield wipers of batteries in you new BMW car, we will disable it permanently and you will have no recourse".

Outrageous.

Steve Jobs' hypocrisy is bothersome: he ranted and raved against locked audio downloads, but thinks it is ok to screw customers who challenged his contract with AT&T.
I find his conduct (actively ruining people's phones) revolting. It is not that the damage to the phone was done by the hacks but it was done by his company's knowingly malicious "update". Seems to me like a class action suit would be appropriate and would set a good precedent.

The obvious fix, of course, is "don't connect the iphone to itunes" and all will be fine. Which is what I did with mine.

Posted by freetheiphonenow 5 years ago ( 01-Oct-2007 11:58:55 )

Please help. I tried the above instructions many times and I keep getting the yellow triangle after downgrading. I use the iBrick phoneinterface to boot it up with fsboot. It does boot, but comes back to the same error message: "Incorrect SIM, insert an unlocked and valid SIM to activate iPhone". I can't use the phone for anything at all. Am I missing something? I am about to throw this thing away! Thank you...

Apple is now writing viruses for their own product! They should at the most reset your phone to initial factory settings, not destroy it!

Posted by freetheiphonenow 5 years ago ( 01-Oct-2007 12:43:10 )

** I forgot to mention that I after dowgrade and get the yellow triangle the following errors happen:
1 "e_failed, Pairing Issue" when using iBrickr iphoneinterface (aftre the fsboot command)
2 "Sending to iPhone Failed" when using appinstaller.
**Any help is very much appreciated**

Posted by clandrea 5 years ago ( 07-Oct-2007 09:27:33 )

Anyone has any comment on after running anySIM "Couldn't load the secpack data" message?
Somebody would know what this means, and if anything about it can be done?
At least I'm getting this different message now, before all I got was that the firmware was already patched.
I would appreciate any help!
Thanks for all the great work.

Hello, I need help. I try to downgrade my Iphone to v1.0.2. I downloaded the firmware 1.0.2. But when I pushed the Option/Alt and Restore Button in iTunes I can´t choose the downloaded firmware. There are a lot of folders and files in this directory but itunes doesn´t accept anything. Is there anything I must do with the downloaded firmware?
Thanks

Posted by gregg 5 years ago ( 24-Nov-2007 22:43:26 )

Dear Nate and fellow iPhone addicts;
I¡¯ve got my unlocked 1.0.2 iphone that was working perfectly on 1.0.2 firmware but is suddenly having trouble with the anysim program and wont unlock. It stuck on the Activate Iphone/Connect to itunes page with my screen saver intact.iBricker sees all the applications and it manages them well, additionally all my photos are retievable.
But I am nearly illiterate and cannot seem to be able to :
Open a command line and cd to the folder you extracted iBrickr to.

How the hack is it done in i have spent hours in my command shell getting no where. Thanks a million. Gregg.

Posted by gregg 5 years ago ( 24-Nov-2007 22:56:39 )

P.S.S.
continued: I was having this same trouble recently everytime the signal would get cut off and a soft reboot or two or three would get it straitened out, and returned on to my T Mobile service.
It now however refuses to find its way back and thus, here I am trying to fix it via Open a command line and cd to the folder you extracted iBrickr to and the iphone interface.exe.(which does work and connect to the phone on its own). gregg.

Posted by kandarp 5 years ago ( 06-Dec-2007 15:30:49 )
