Ifaith For Mac

Downgrade iOS 7 to iOS 6.1.3 on your apple iPhone 4 using iFaith. If you’ve an iPhone 4 and have saved SHSH blobs for iOS 6.1.3, then it is possible to downgrade from iOS 7 to iOS 6.1.3 or earlier using iFaith. We had briefly mentioned this a days back, but we finally managed to successfully downgrade from iOS 7 to iOS 6.1.3, so. IFaith is available for the PC (Mac coming soon) and is currently online for user use. The following link is a download link of iFaith for PC. IFaith - PC Project iF (iFaith) can be followed on Twitter for new developments and updates on the software. The creator, iH8sn0w, can also be followed on Twitter. IFaith also differs from TinyUmbrella because it ties into its own caching server, while TinyUmbrella relies on Cydia’s server for retrieving SHSH blobs. Lastly, iFaith features the ability to boot into PwnedDFU mode, which is a special type of recovery mode that’s necessary for iTunes to recognize and restore to custom created firmware. IREB for Mac comes with one feature only that is restoring custom firmware on supported devices using limera1n exploit. However, Windows variant of the app also comes with Recovery Loop fix and SHSH grabbing function as well, that are yet to be added in the Mac variant. Like TinyUmbrella, iFaith allows you to save your device’s SHSH blobs, which are needed to preserve your ability to downgrade firmware in the future. The update supports iOS versions up to 5.0.1, but isn’t yet compatible with A5 iDevices. There also doesn’t seem to be a Mac version available.

1Source Code

iFaith is an open source SHSH dumper for the Windows family of operating systems written by iH8sn0w. It works on all devices that are susceptible to the limera1n exploit (all devices before the iPad 2). This is useful if you receive a device with old firmware on it that you want to be able to restore. Even if Apple doesn't sign that firmware anymore, you can backup the SHSH data directly from the device, so that you can install the firmware later again to avoid upgrading the firmware.

Source Code

The source code of iFaith 1.2 is available under the GNU General Public License v3. Other versions are not available.

License

What is interesting is how iFaith uses xpwn (xpwntool and hfsplus) while being able to be closed source. The reason is that the GNU GPL v3 requires derivatives of GPL software and programs utilizing GPL libraries (static or dynamic) to be under the GNU GPL v3 or (at their discretion) a later version. iFaith works around this the same way OS X does - by using a compiled executable, not a library.

Version	Release date	Changes
1.0	2 Jun 2011	Official release of iFaith
1.1	2 Jul 2011	Code improvement. iFaith now SHA1's the SHSH blob. Now alerts user when iFaith was unable to hook iTunes instead of crashing. Minor bug fixes with device / iOS detection.
1.2	27 Jul 2011	Added iPod touch (2nd generation) dumping capability (MC-Model users recommened) IPSW Creation for iPod touch (2nd generation) is still a work in progress. Fixed exe compression issues (resulting in many DFU loops on IPSW creation) Fixed any Windows XP issues Source code released It is currently not possible to add iPad 2 support
1.2.1	27 Jul 2011	Bugfix ('Who knew one last second mod could screw the whole build?')
1.2.2	31 Jul 2011(?)	Contains a minor fix.
1.3	9 Aug 2011	DFU loops were being caused on devices that had the factory certificate. On this new version, when building the signed IPSW, if you were getting a DFU loop, say 'NO' to the prompt about using the standard signing certificate. You can now use TinyUmbrella blobs to build a signed IPSW. (Change file type in browse dialog to 'TinyUmbrellaSHSH blobs'.) Now adds ECID to beginning of the SHSH filename after dumping. Now adds ECID to beginning of the IPSW filename after being built. Cleaned up code and payload It's not possible to add iPad 2 support until a bootrom exploit arises.
1.3.1	12 Aug 2011	Used a different method to convert binary plists from TinyUmbrella SHSH Blobs to xml format to parse. Fixed minor restore issues on 4.3.x for iPad 3G models.
1.3.2	14 Aug 2011	The .NET framework that came pre-shipped with Windows Vista didn't have an essential resource used in iFaith. A new method has been implemented to get around this requirement. Fixed issue where iTunes' plist utility was unable to be located on international language formatted pcs.
1.4	3 Dec 2011	Now dumps iOS 4.4.x (Apple TV (2nd generation))/5.0.x apticket + SHSH blobs! Dumping is MUCH faster. Full Windows XP support. Major code improvements. Bug fixes.

1.5	3 Feb 2013	Finally fully fixes NAND issues with newer models (e.g iPhone 4 8GB, new iPod touch (4th generation) models). Finally enabled 3.x.x IPSW creation for iPod touch (2nd generation) users. Crazy payload rewrite. (There are a chain of payloads used in this new iFaith purely dedicated to bumping up performance. iFaith should dump instantly after payload executes!). Adds the ability to dump iOS 5.1.x/6.0.x/6.1 on the iPhone 3GS, iPod Touch (3rd generation), and A4 devices. Added Check for Update code. Major code improvements.
1.5.1	3 Feb 2013	Fixed a bug where iFaith did not submit the latest SHSH blobs Apple is actively signing to Cydia's server when dumping
