How to fix iBooks "Configuration Error" after 5.0.1 untethered jailbreak on iPhone and iPad ? Well, MuscleNerd of iPhone Dev-team has just announced today about the release of Redsn0w 0.9.10 b4 to fix iBooks issue after 5.0.1 untethered jailbreak. Dev-team was managed to merge Corona 1.0-5 into Redsn0w 0.9.10 b4.
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).Here's the iBooks error message "Configuration Error, There is a problem with the configuration of your iPhone. Please restore with iTunes or redo unload iBooks". So if you got this message, don't worry, we have a fix for this.
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”.
