How to Jailbreak iOS 5.0.1 Untethered with redsn0w 0.9.10b4 [Fixes iBooks issues]

in iPhone Fix & Repair by

RedSn0w was just recently updated to 0.9.10b4! Fixes iBooks issues!

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).

iBooks Configuration Error There is a problem with the configuration of your iPhone. Please restore with iTunes or redownload iBooks

Already Jailbroken?

  • If you are Jailbroken already on iOS 5.0.1 with the past redsn0w’s:
    • [0.9.10b1]
    • [0.9.10b2]
    • [0.9.10b3]

then you can still run this jailbreak over that jailbreak. You will simply have to UNCHECK “Install Cydia” in redsn0w when you are prompted that screen.


  • If you are running a TETHERED Jailbreak on 5.0.1, simply download “Coronoa 5.0.1 Untether” from Cydia. This will convert you from a TETHERED state to an UNTETHERED state with it being installed on your device. [YOU MUST BE JAILBROKEN ON 5.0.1 FOR IT TO WORK]

What does UNTETHERED mean?
means you can use your device as normal, unlike tethered jailbreak.
