Redsn0w v0.9.10b5 iOS 5.0.1 Untethered Jailbreak for A4 Devices Released

**نصير الاسلام** · 30-01-2012, 06:58 AM

@pod2g has created a terrific gift for iOS fans — an untethered 5.0.1 jailbreak for non-A5 devices!

Many of you have already been following @pod2g’s blog where he’s been keeping everyone up to date on his progress. And so you know that he recently decided to push the button on a release for all devices except the new iPhone4S and iPad2. @pod2g’s untether involves two separate exploits and a few other “tricks” — and since he’s taken the @comex approach of doing nearly everything himself, you know his plate has been full these past few months!

A few days ago, @pod2g gave the untether to both the iPhone devteam and the chronic devteam. We’ve put it into redsn0w 0.9.10 and PwnageTool, and the chronic devteam put it into a Cydia package (the same set of exploits is in all three).

Here are the basic steps for how to get it:

• The untether is for iOS 5.0.1 on iPhone3GS, iPhone4, iPhone4-CDMA, iPad1, iPod touch 3G, iPod touch 4G

• If you have one of those devices and are not on 5.0.1 yet, update now! The SHSH window is still open for 5.0.1 If you unlock via ultrasn0w or gevey, make sure you only get to 5.0.1 via a custom IPSW! See the guides at places like iClarified.com if you don’t know how. Once you’re at 5.0.1, use the latest redsn0w 0.9.10 to both jailbreak and untether.

• If you’re already at 5.0.1 with a tethered jailbreak, you have two choices: either run redsn0w 0.9.10 over your current jailbreak (deselect “Install Cydia” if you do that), or install the Cydia package prepared by the chronic devteam. The patches are the same regardless of which you choose.

• Some of you are using a hybrid 5.0/5.0.1 configuration. If so, do not attempt to install this untether over that setup! You will most likely get into a reboot cycle. Do a sync and fresh restore to 5.0.1 then install the jailbreak + untether.

• As mentioned earlier, @pod2g has spent months working on all the exploits and tricks in this untether, and many of you may be wondering how you can send donations. Although the iPhone devteam itself doesn’t take donations, we thought it was appropriate to provide a link at the end of the redsn0w run for you to more easily donate directly to @pod2g if you wish (alternatively, you can go right here). There’s a link in the Cydia package for donating to the chronic devteam for the Cydia version of @pod2g’s untether.

• @pod2g is now looking for a way to extend this to A5 devices. Because those devices cannot use geohot’s limera1n exploit to inject the untether, they require exploits above and beyond those used for this release. Keep following pod2g on twitter or his blog for any progress reports!

How To: Jailbreak iOS 5.0.1 Untethered using latest redsn0w

=============================================

Update #2:
The b2 version of redsn0w includes the launchctl-related fix by @planetbeing as mentioned by @saurik here and here. As usual, you can just re-run redsn0w in jailbreak mode over your existing 5.0.1 jailbreak (even a PwnageTool one), making sure to de-select “Install Cydia” if you do. Always be sure to do a controlled “slide to power off” shutdown of your device before running redsn0w.

Update #3:
The b3 version of redsn0w fixes a problem where re-running redsn0w over an existing jailbreak would cause MobileSubstrate-based apps to stop running until MS was installed again. Now you can re-run the redsn0w jailbreak step without worrying about that (but still remember to de-select the “Install Cydia” option if it’s already installed).
TIP: If auto-detection fails and redsn0w tells you no identifying data was found, you can always pre-select the appropriate 5.0.1 IPSW using “Extras->Select IPSW”.

Update #4:
The b4 version of redsn0w incorporates the 5.0.1 fix for iBooks, and also for sporadic problems with launchctl. Thanks to @xvolks for merging the iBooks (sandbox) fix from @comex's github into the overall corona untether from @pod2g! As usual, you can choose to install the fix either by re-running redsn0w over your existing jailbreak (de-select Cydia if you do that), or by installing the corona package from Cydia (it's the same set of files no matter which way you choose).

Update #5:
redsn0w version b5 incorporates yet another fix for iBooks, this time involving DRM. *@planetbeing wrote a utility called “crazeles” that overcomes jailbreak detection by iBooks that would cause about 10% of images to show incorrectly. *This fix is similar to the “hunnypot” fix that @comex wrote for the 4.x jailbreak. *As usual, you can choose to install the fix either by re-running redsn0w over your existing jailbreak (de-select Cydia if you do that), or by installing the corona package from Cydia (it’s the same set of files no matter which way you choose).
