Preventing Baseband Update

2011-04-06T19:32:44Z

Gojohnnyboi: /* Edit options.plist */

===Edit options.plist===
# Unpack custom IPSW
# Decrypt Restore Ramdisk using [[xpwntool]] and mount it
# Navigate to /usr/local/share/restore
# Edit options.plist on the restore ramdisk
(Ignore any other settings specified in the plist, don't edit them)
<pre>
<key>UpdateBaseband</key>
<false/>
</pre>
<ol start="5">
<li>Reencrypt the restore ramdisk</li>
<li>Repack the IPSW</li>
<li>Prepare device for custom firmware using [[redsn0w]]</li>
<li>Restore IPSW to [[iTunes]] in pwned [[DFU Mode]] using the appropriate method(Look at Restoring The Modified IPSW Section)</li>
</ol>

You must load a patched [[iBSS]]/[[iBEC]] for this to work. Using an original IPSW will not work, because redsn0w's pwned DFU Mode doesn't patch sigchecks in [[iBSS]] (which is loaded from the IPSW).

===Idea===
One could hook the function HookAMRestorePerformRecoveryModeRestore in MobileDevice which iTunes uses, overriding the restore options CFDictionaryRef object. This would *THEORETICALLY* allow for not updating baseband without patches/jailbreak. A practical application for this is if someone absolutely needs to update to the latest firmware for work or other reasons, and can't as they must wait for PwnageTool to provide support.

==Restoring The Modified IPSW==
Firmwares like 4.2.1 and above have baseband checks on the [[Restore Ramdisk]].If the modified IPSW is restored, iTunes will give a Error 1015 and iPhone will be in a recovery mode loop which cannot be exited by TinyUmbrella or the 'setenv auto-boot true' command<br />
Fortunately, the [[Update Ramdisk]] does not contain that baseband check so if the Update Method is used which is mentioned below,iTunes will give error 1013 and it can be exited by TinyUmbrella and the irecovery command.
===Update Method===
*Windows Users, Open iTunes. hold the Shift button and click Update then select the modified IPSW
*Mac Users, Open iTunes, hold the Alt button and click Update then select the modified IPSW
===Restore Method===
*Windows Users, Open iTunes. hold the Shift button and click Restore then select the modified IPSW
*Mac Users, Open iTunes, hold the Alt button and click Restore then select the modified IPSW

==[[TinyUmbrella]]/[[Cydia Server]] Method (iPhone 4)==

The [[N90ap|iPhone 4]] requires a [[AT+XNONCE]] key signature from Apple in order to update the baseband. Pointing the hosts file to [[Cydia Server]] or running [[TinyUmbrella]] will allow this request for signature to be ignored, thus preventing a [[baseband]] update.

*'''This only works if [[Cydia Server]]/[[TinyUmbrella]] accepts the firmware's SHSH.'''
*'''This method 'works' with [[iOS]] 4.2.1, but in the restore ramdisk there is a baseband version check. If it doesn't match, it will crash before the Apple logo with the loading bar (the 2nd, first-boot one, not the restore one) appears. It will boot and crash again. The old 'Kick out of recovery mode' methods or "setenv auto-boot true" won't work, because it's not the problem that the auto-boot is false. So this method is actually not useful for [[iOS]] 4.2.1+.'''
*'''[[greenpois0n (jailbreak)|greenpois0n]] RC6 will fix this as part of the jailbreaking process. The latest version of TinyUmbrella also features a new Fix Recovery function.'''
# Edit the hosts file and add the line "74.208.10.249 gs.apple.com" without the quotes, or run [[TinyUmbrella]] after saving the firmware's SHSH. If [[Cydia Server]] hasn't got your [[SHSH]], but you have it locally, use TSS Server method in [[TinyUmbrella]].
# Use the "Restore" button in [[iTunes]] to update if your firmware version is below 4.2 else use the "Update" button in [[iTunes]] to update.
# You will get Error 1013 and it can be easily bypassed by using the Exit Recovery Mode button in [[TinyUmbrella]] or typing 'setenv auto-boot true' and 'saveenv' in [[iRecovery]]

==[[User:Ih8sn0w|iH8Sn0w]]'s Method==
[[Sn0wbreeze]] has a "Baseband Preservation Mode" since version 2.2. User [[User:Ih8sn0w|IH8sn0w]] [http://twitter.com/iH8sn0w/status/19453808090288128 confirmed] that his method is not the same as the above mentioned methods.

This method can also be used on the iPhone 3GS and the iPhone 4 to downgrade from the 4.3 betas back to 4.2.1, as long as the device can be restored (and activated) to iOS 4.1 or an earlier version.

To get some more details about what [[sn0wbreeze]] with the option "Baseband Preservation Mode" does, here a short analysis - a comparison of the generated ipsw for iOS 4.3 (iPhone 4):
===root filesystem 038-0688-006.dmg===
I couldn't get vfdecrypt to run, so I cannot list the details. It is much smaller (360MB instead of 615MB), probably just without the baseband. (Details to be added.)
===restore ramdisk 038-0715-006.dmg===
====options.plist====
The file options.plist in the folder \ramdisk\usr\local\share\restore is changed. These are the changes:
*first entry added: CreateFilesystemPartitions = true
*changed value: SystemPartitionSize 1024 changed to 1050
*added last entry: UpdateBaseband = false
====asr====
In the folder \ramdisk\usr\sbin\ the file asr has been renamed to asr_orig and a patched file of size 180832 bytes added. The patches are:

0001321A: DF F8
0001321A: FD E7

0002C1BA: FA DE 0C 01
0002C1BA: F6 B6 D0 8F

====images====
Two files were changed from the Apple logo to the iH8sn0w logo. Both are called applelogo.png and they are located in \ramdisk\usr\share\progressui\images-1x\ and in \ramdisk\usr\share\progressui\images-2x\.
===patches in [[iBSS]]===
There are several patches in [[iBSS]] (first line is original, second line is the patched version):

===AFC Connection===
...

===Locking the Device for Sync===
When iTunes sends a new song to the device, the device shows a "Sync in progress" screen and when complete, the Music app on the device re-reads the iTunesDB file so it picks up the new song.

To get this behaviour, first start the notification service:
<pre>SOCKET socket;
AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);</pre>

Now we post a notificaton message to signal that we are going to start a sync:
<pre>AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncWillStart"), NULL);</pre>

Next we open the itunes lock file:
<pre>afc_file_ref lockref;
AFCFileRefOpen(conn, "/com.apple.itunes.lock_sync", 2, &lockref);</pre>

Now post a notification to say we are going to lock this file, and try and lock it.
If the AFCFileRefLock call fails, pause and repeat.
<pre>AMDPostNotification(socket, CFSTR("com.apple.itunes-mobdev.syncLockRequest"), NULL);
mach_error_t error = AFCFileRefLock(conn, lockref);</pre>

When the file is successfully locked, post another notification, and stop the notification service.
<pre>AMDPostNotification(socket,CFSTR("com.apple.itunes-mobdev.syncDidStart"), NULL);
AMDShutdownNotificationProxy(socket);</pre>

Now the sync can proceed, so copy your files across and make the changes to the iTunesDB.

To release the lock, start the notification system again, unlock and close the lock file, and send a sync finished notification message:

<pre>AFCFileRefUnlock(conn, lockref);
AFCFileRefClose(conn, lockref);
AMDeviceStartService(dev, CFSTR("com.apple.mobile.notification_proxy"), &socket, NULL);
AMDPostNotification(socket, &CFSTR("com.apple.itunes-mobdev.syncDidFinish"), NULL);
AMDShutdownNotificationProxy(socket);</pre>

To handle "Slide to Cancel" and terminate sync when user slides cancel switch, use AMDObserveNotification to subscribe notifications about “com.apple.itunes-client.syncCancelRequest”. Then start listening for notifications (AMDListenForNotifications) until you get “AMDNotificationFaceplant”.
When notification got, you should unlock and close lock file handle (don’t sure if you need to post “syncDidFinish” to proxy, seems it doesn’t matter) and terminate sync gracefully.
The same notification is also got when you unplug your device, so you should always be ready for errors.

NOTE: You may find that starting the notification_proxy service once and once only at the start of your app and using the same socket in calls to AMDPostNotification works better. iTunes opens and closes the notification_proxy regularly, but it appears to be a bit flakey when you open/close it all the time.

===Private Functions===

====How to find address of privates functions in iTunesMobileDevice.dll or MobileDevice.framework====

In order to obtain the address of a usable private function in MobileDevice, you will have to be able to understand x86-64 assembly to reverse engineer it. A private function will not have its name exported in the mach-o symbol table, so in a debugger, like GDB, it will show up as part of another function. However, you will know that it is a separate function as a new stack frame is set up.

====Private Function Address List====

=====OSX.6 - iTunes 9.0.2(25)=====
<pre>unsigned int sendCommandToiBoot(struct am_recovery_device *rdev, CFStringRef command, int u);</pre>
Address is obtainable by adding 868(0x364) to the address of AMRecoveryDeviceGetProductType(), a public symbol that you can obtain via nlist() or dlsym().
Address: 0x1000245ea

Parameters
1. rdev - the device you wish to send the command to.
2. a CFStringRef of the command to send.
3. an integer, whose use is currently unknown, but should be set to 0 to work.

<pre>unsigned int sendFileToiDevice(struct am_recovery_device *rdev, CFStringRef filename);</pre>
Address is obtainable by adding 1763(0x6e3) to the address of AMRecoveryDeviceGetProductType(), a public symbol that you can obtain via nlist() or dlsym().
Address: 0x100024969

Parameters
1. rdev - the device you wish to send the file to.
2. a CFStringRef of the path to the file to send.

=====OSX.6 - iTunes 9.0.3(15)=====
<pre>unsigned int sendCommandToiBoot(struct am_recovery_device *rdev, CFStringRef command, int u);</pre>
Addresss: AMRecoveryDeviceGetProductType() + 0x37f(895); full offset: 0x2a0ed

<pre>unsigned int sendFileToiDevice(struct am_recovery_device *rdev, CFStringRef filename);</pre>
Address: AMRecoveryDeviceGetProductType()+0x6f3(1790); full offset: 0x2a46c

As of now, Apple has decided to make this functions public with the following names:

_AMRecoveryModeDeviceSendFileToDevice
_AMRecoveryModeDeviceSendCommandToDevice
_AMRecoveryModeDeviceSendBlindCommandToDevice

The last of those returns no response from the device. I can only assume that the parameters to these functions are the same or similar to the private ones. They're not the exact same function though, as it appears that these functions call the previously private ones.

* [http://www.libimobiledevice.org/ Libimobiledevice (provides the same functionality on GNU/Linux)]

Talk:Ramdisk Hack

2010-04-30T00:11:09Z

Gojohnnyboi: /* To the idiot that wrote the last comment about Zibri */

This is just a 'overall' explanations to give someone that is not involved a 'clue'.

Could please someone explain more specifically to enable an experienced user to follow the hack?

== Ramdisk Hack ==

It's not difficult at all. You just send a file to 1.1.4 or lower iBoot (iphuc: sendfiletophone or something) then "change" some boot-args. -wEsTbAeR--

I believe that it is not difficult. But where do you put the file and how do you change boot args. And how you put the file there, because at this point it isn't jailbreaked yet!? -caique2001-

== Re: Ramdisk Hack ==

We don't talk to the iPhone via AFC. We talk to the iBoot (Recovery Mode), which is implemented in iPHUC too.
In iBoot you upload a file to RAM (no jailbreak required) and then change boot-args to boot it.

* setenv boot-args rd=md0 -s -x pmd0=0x9340000.0xA00000
* saveenv
* fsboot

I'm not sure about the last command, you must try it. If it does not work, try 'bootx'.

== To the idiot that wrote the last comment about Zibri ==

Get the fuck out of the community, and stop sucking dick. This is for facts, not fanboism.

//cmdshft

cmdshift: you are the idiot. it was a joke, and i believe it was posted by a member of the dev team, planetbeing. saying that he "invented ramdisks" and their workings is absolutely ridiculous, and that sir, is a fact. get over yourself.

// gojohnnyboi

How the fuck are you supposed to tell that it is a joke without at least a comment in the discussion page? People have been known to still give him way more credit than he deserves.

// cmdshft

because maybe... well.. um... its all an extreme hyperbole? of course he didn't invent ramdisks.

Gojohnnyboi: /* iPhone/iPod Touch */

This article explains how to build a tool chain for iPhone OS 2.0.

'''Please note that this section is under development.'''

__TOC__

== Mac OS X ==
fill this in. somebody did not get this memo :P

toolchain != apple sdk

== Windows XP ==

=== Extraction of iPhone OS 2.0 SDK ===
* Download the iPhone OS 2.0 SDK from [http://developer.apple.com/iphone/index.action Apple iPhone Dev Center].
* Download and install ''HFSExplorer'' from [http://hem.bredband.net/catacombae/hfsx.html catacombae software].
* Start ''HFSExplorer'' and choose the menu ''File→Open UDIF Disk Image (.dmg)...''
* Select the iPhone 2.0 SDK disk image ''iphone_sdk_final.dmg'' and press ''Open''
* When the tool asks ''Which partition to read'' leave it at ''"Mac_OS_X" (Apple_HFS)'' and press ''OK''
* Go to ''Packages'' and select the package you want to extract, e.g. ''iPhoneSDKHeadersAndLibs.pkg'' for the iPhone OS 2.0 header files.
* With right mouse button choose ''Extract data'' to extract an installation package.
* Please note that in order to extract this .pkg file on Windows, you must compile xar using Cygwin. Make sure you have libxml. You can then follow the instructions below.

== Linux ==
Currently we can only describe how to get the headers from the iPhone OS 2.0 SDK.

=== Extraction of iPhone OS 2.0 Installation Packages (.pkg) ===
* Extract <tt>iPhoneSDKHeadersAndLibs.pkg</tt> from iPhone OS 2.0 SDK:
mount -t hfs -o loop /path/to/iphone_sdk_final.dmg /somepath/somedir
:Copy <tt>iPhoneSDKHeadersAndLibs.pkg</tt> from <tt>/somepath/somedir</tt>
* Use the ''eXtensible ARchiver'' <tt>xar</tt> to extract the file <tt>Payload</tt> file containing the actual header files:
xar -xf iPhoneSDKHeadersAndLibs.pkg Payload
* Rename the <tt>Payload</tt> file since it is gzipped:
mv Payload Payload.gz
* Uncompress the <tt>Payload.gz</tt> file:
gunzip Payload.gz
* Extract the contents of the resulting <tt>Payload</tt> file:
cat Payload | cpio -i
or
cat Payload | cpio -i -d '*.h'
to extract only all header files included in the package.

=== Framework Headers ===
This section assumes that
cat Payload | cpio -i -d '*.h'
got used in previous section.

If you want to move all Framework headers into an ''include'' directory continue
as follows:

* Remove the project XCode templates since they will not be required anymore:
rm -rf Platforms/iPhoneOS.platform/Developer/Library

* Create your target ''include'' directory:
mkdir include

* Get just the ''System'' and ''usr'' directories from the iPhone Os 2.0 SDK and remove the empty ''Platforms'' directory hierarchy:
mv Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/* .
rmdir -p Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.0.sdk/

* Move the Framework headers to current directory and clean-up empty directory hierarchy:
mv System/Library/Frameworks/* .
rmdir -p System/Library/Frameworks/

* Rename/move all Framework header directories into ''include'' directory and cleanup
mv AddressBook.framework/Headers include/AddressBook
mv AddressBookUI.framework/Headers include/AddressBookUI
mv AudioToolbox.framework/Headers include/AudioToolbox
mv AudioUnit.framework/Headers include/AudioUnit
mv CFNetwork.framework/Headers include/CFNetwork
mv CoreAudio.framework/Headers include/CoreAudio
mv CoreFoundation.framework/Headers include/CoreFoundation
mv CoreGraphics.framework/Headers include/CoreGraphics
mv CoreLocation.framework/Headers include/CoreLocation
mv Foundation.framework/Headers include/Foundation
mv MediaPlayer.framework/Headers include/MediaPlayer
mv OpenAL.framework/Headers include/OpenAL
mv OpenGLES.framework/Headers include/OpenGLES
mv QuartzCore.framework/Headers include/QuartzCore
mv Security.framework/Headers include/Security
mv SystemConfiguration.framework/Headers include/SystemConfiguration
mv UIKit.framework/Headers include/UIKit
rmdir -p *.framework

* The remaining directories are ''include'' with all Framework headers and ''usr'' with all system related headers.

* You may still remove the ''Payload'' file since we don't need it anymore:
rm Payload

* You are done.

== iPhone/iPod Touch ==
There is a tool chain available after jailbreak from the [[Cydia|Cydia installer]]. You just need to install
the '''iPhone 2.0 Toolchain''' from Cydia to get a 1.1.x based development environment on your iPhone
or iPod Touch. The maintainer of this package - BigBoss - has some comments on this Toolchain on his
webpage ''[http://thebigboss.org/moreinfo/Toolchain2.php Toolchain 2.0]''.

If you want to use the header files from iPhone OS 2.0, you can obtain them from the
iPhone OS 2.0 SDK as described in section ''[[#Framework Headers|Framework Headers]]''.

**NOTE**
When using iphone-gcc ( the native compiler ) to compile iPhone applications, you must do one of the following:
1. Patch the SDK header files for use with the compiler ( stupid thing doesn't like the new headers! )
or
2. Use the old header files ( which are great, but some things dont work/exist the same anymore! )
