iPhone OS Restore Image (93MB)

Inventive users can download the iPhone 1A543a restore image (93MB) from Apple.

The link was discovered through iTunes 7.3, which offers users the capability to restore their iPhone to factory default settings. The resultant .zip file provides a Firmware Folder and two DMG (one password protected).

There have been some ongoing efforts to unlock the Apple iPhone, but no documented success. According to one blogger, the Apple iPhone becomes locked to your SIM which you use to activate it (photo), but the iPhone's SIM can succesfully be used in another AT&T phone.

i think apple removed this from their website. When i click on the link it says that is cant be found on their server and then it suggests another document, which is the OS but i can't get to that either. I hope whoever has the image saved, will try to hack it and work their way to unlocking it;)

Referring to the picture from Flickr,
What happens when you press 'Dismiss'?
Does it let you use the iPod or data through Wifi?

yeh will someone please try that

from the picture it looks like that would work. If so, then one would have to activate the phone with the sim card, then take it out, and put in a different sim card, and cancel the service with AT&T. Then one would be able to use all the features besides the phone for the cost of the $36 activation fee plus another sim card.

Someone please try this with an iphone.

P.S. Is it possible to boot from this image on a computer just like people booted from the Apple T.V. image on their computers.

I really, really doubt it. The phone's OS is compiled to run on ARM processors, not Intels, for starters.

Now an emulation layer may show up someday so you can run the phone's OS inside a window. That would be fun, even if not really useful.

This is a interesting discovery! Not only do we now have the OS to the iPhone it includes some additional information. One major point being that the iPhone contains a preset RAM image. Which is... weird.

DMG: 694-5259-38.dmg
Contains: RAM image. Along with most instructions for the iPhone (try opening it with a hex editor and you will see what I mean).
Notes: This 'disk image' has the right extension but the data inside has been stored in a way that has an unusual format and Disk Utility cant mount it because of this. I have tried other utilities for mounting the image and repairing it etc. Nothing so far has worked. :(

DMG: 694-5262-39.dmg
Contains: The OS (which is a stripped down version of Leopard) and the extensions/modifications needed to use features of the iPhone.
Notes: This disk image is is the right format and can be mounted. Unfortunately that would require a password because it is protected. I know a few people have been running brute force attacks on the password with no luck so far. :(


The next part of the iPhone package is the two other files inside the main folder (not the Firmware folder)

File: kernelcache.restore.release.s5l8900xrb
Contains: The cache of the kernel stored on the iPhone. It's encrypted so I can't grab much from this.
Notes: This is encrypted. The key must either be on the iPhone OS its self to decrypt the contents. Or the key is in iTunes.

File: Restore.plist
Contains: This holds key information about the iPhone's restore process. If it can be applied etc.
Notes: None. Just open and your done. Altho you might be able to change the location of the firmware that it restores (You can change it, but some other part of the restore might not like that)


Next bit is the Firmware folder. Surprise, surprise this contains the firmware and its resources so I don't really need to run over the files because its mostly self explanatory. But here is the contents.

Folder: Firmware
Contents: [LIST]
[*]all_flash[LIST=1]
[*]all_flash.m68ap.production[LIST=1]
[*]applelogo.img2
[*]batterycharging.img2
[*]batterylow0.img2
[*]batterylow1.img2
[*]DeviceTree.m68ap.img2
[*]iBoot.m68ap.RELEASE.img2
[*]LLB.m68ap.RELEASE.img2
[*]manifest
[*]needservice.img2
[*]recoverymode.img2
[/LIST]
[/LIST]
[*]dfu[LIST=1]
[*]iBSS.m68ap.RELEASE.dfu
[*]WTF.s5l8900xall.RELEASE.dfu
[/LIST]
[/LIST]

The file, manifest, checks all the files for modifications.

Also .img2 has no resemblance to pictures except they may contain some.


Thats all I've got so far. Hope it helps!

I dont think the moderators would appreciate me talking about that kind of thing here so I will PM you with some details. There arent many tools out there for .dmg files.

Edit: If anyone else wants to do that kind of thing just PM me.

.dmg files use 128 bit AES encryption. Brute forcing is not an option unless you have several millennia to spare.

oh come now...in 5 years the budget processor of the time will be able to crack it in under a minute. But who will care by then???
