Is There Ifaith For Mac

IFaith can pull the blobs off the device for that specific firmware you're using. Then you can use them to reinstal that same firmware. If your blobs on Cydia are invalid and you want to use iFaith to install a firmware you are not currently using, then there's nothing you can do about that.
However, iFaith, the tool that works the magic, has yet to be updated beyond supporting iOS 6.1.3, so for the time being, those on iPhone 4 or iPad 2 looking to downgrade iOS 7.1.1 / 7.1 to 7.0.6 will need to sit tight and hope that an iFaith update does come along.

One more thing; iFaith only available for Windows operating systems, so if you have Mac OS, then avoid downgrading on Mac OS and install iFaith on Windows operating system. Detailed steps provided below 1. IFaith works only Windows operating system, So, Download iFaith v1.5.9 using your Windows PC.

iFaith, originally codenamed Project iF, was released today by iH8sn0w (@iH8sn0w) after his first live demo of the application. An announcement this last Sunday gave information on where to watch for the release of iFaith but it was unknown about what the project consisted of and what its true name was. Today's live stream by iH8sn0w showcased the world's first public SHSH dumper.
A project that includes previous projects by iH8sn0w, iFaith is the first application to have the ability to dump SHSH blobs onto your physical device. iH8sn0w elaborated in his live stream on how iFaith works and reasons why it will be a useful tool: For

Because it dumps SHSH physically onto your device, it alleviates issues with having to upgrade to a firmware that is not currently jailbreakable.
For example, if you buy another iDevice, it comes with a preloaded iOS version. Even if that version is currently jailbreakable, when Apple updates the firmware to a new version, they not longer need to sign signatures on SHSH blobs for lower versions.
This means that you no longer have SHSH retrieval for that particular firmware. If you run into an issue of restore or device corruption, you have to update to the latest firmware and have no way of downgrading. With iFaith, you're now able to place SHSH blobs directly onto your device thus removing an issue of unnecessary iOS upgrading.
Programs like TinyUmbrella and Cydia are able to store SHSH blobs but are limited in capabilities. These programs do not allow physical retrieval of SHSH blobs and they only can retrieve SHSH blobs that are currently signed by Apple. For this reason, the SHSH blobs are on a time constraint.

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.

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 History

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.
1.4.1	20 Dec 2011	Added Apple TV 4.4.4 (9A406a) support. TinyUmbrellaiOS 4.4.x/5.x.x blobs are now accepted. Resolved rare DFU detection issues. Resolved issues with 8GB iPhone 4 Models. Resolved iPhone 3GS issues with factory certificates/Error 21 that occurred during restore. Resolved iOS Detection issues. Removed kill-switch that accidentally got distributed in iFaith-v1.4's public release.
1.4.2	7 Feb 2012	Made the limera1n icon higher-res. Fixed looping issues. Fixed Oversized APTicket issues with TinyUmbrella blobs. Speed Enhancements
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
1.5.2	5 Feb 2013	Fixed bug with 3.x.x/4.x.x dumps.
1.5.3	23 Feb 2013	Now dumps 3GS/A4 devices running iOS 6.1.2. Fixed Windows XP USB issues. Fixed annoying bug when downloading blobs from server(s). More bug fixes Minor UI improvements. More iPhone 4-Rev2 fixes (Still needs more feedback).

1.5.5	10 Mar 2013	Finally fixed iPhone3,2 limera1n issues.
1.5.6	26 Mar 2013	Adds 5.2.1/6.1.3 dumping capabilities on 3GS/A4 devices APTicket validation
1.5.7	10 Apr 2013	Added ability to submit locally saved blobs (from other apps such as TinyUmbrella, iSHSHit, redsn0w) directly to Cydia [Simply click the 'Show available SHSH blobs on Server' button and connect a device]. Slight UI improvements.
