How to Fix iBooks issue in iOS 4.2.1 Greenpois0n Jailbreak

iBooks refuse to open on iPhones Jailbroken with greenpois0n on iOS 4.2.1 firmware. Users who attempt to open books purchased from the iBook store are prompted with the following error message: There is a problem with the configuration of your iPhone. Please restore with iTunes and reinstall iBooks. And, if you restore your device from iTunes, it will remove the jailbreak. Follow the steps below to fix iBooks problem on iOS devices jailbroken with greenpois0n.

Why iBooks fail to open on jailbroken device?

Whenever a user tries to open a Book purchased from the iBookstore, iBooks tries to run unsigned or improperly signed binaries as a test to see if the device is jailbroken. If those binaries run successfully, the device is marked as having been jailbroken and the eBook refuses to open.

Pre-requisites

  • Jailbroken iOS device with greenpois0n
  • MobileTerminal must be installed on the device.
  • A SSH client for your computer (Windows: WinSCP – Mac: Cyberduck ).
  • Download the fix files for iBooks.

How to Fix iBooks Problem on Jailbroken iPhone, iPad, iPod touch on iOS 4.2.1

Step 1: UnZip the downloaded fix file and locate the file ibookfix.sh under folder script.

Step 2: Copy the file into folder /var/mobile/device (via SSH or iFile).

Step 3: Launch MobileTerminal on your device and type and run the following commands one by one:

su root
Alpine
. /Ibooksfix.sh

Step 4: Select your iPhone/ iPod touch model by typing the number in front of your model.(eg “3″ if you have an iPhone 4 and “4″ for Veerizon iPhone 4). For all other models refer the screen below:

Step 5: Wait for few seconds until following message appears: “If the procedure was successfully completed, respring or reboot your iPhone to complete the operation!”

Step 6: Reboot the device! Thats it!

iPhone Dev team and iH8sn0w has already ported the iBooks fix into PwnageTool 4.2sn0wbreeze 2.2 respectively. If you haven’t already jailbroken your device, you can use pwnagetool 4.2 (for Mac) or sn0wbreeze 2.2 (for Windows). Both these tools will retain your carrier unlock on old baseband in addition to fixing your iBooks issue.

Another untethered vulnerability found for iOS 4.2.1

iPhone hacker pod2g, the hacker who discovered SHAtter jailbreak exploit and the untethered jailbreak for iOS 4.2.1, has discovered a new jailbreak vulnerability in iOS which can be used on iOS 4.2.1 and 4.3 as well.

Hey, another untethered vulnerability found ! 🙂

Since greenpois0n untethered jailbreak for iOS 4.2.1 won’t support iOS 4.3, this new vulnerability will support iOS 4.3 and bring untethered jailbreak once iOS 4.3 is released to public. [Source:Twitter]

 

Macworld Staffer Chose to Jailbreak iPad iOS 4.2.1 for Supersession

In a first for the mainstream Macworld.com, staffer Christopher Breen and Ben Long chose to jailbreak their iPad to display crystal-clear view of iPad at last week’s Macworld. Instead of going with Elmo projector system, Breen found an alternative in the form of a jailbroken iPad to offer perfect presentations.

Christopher Breen simply used redsn0w tool for iOS 4.2.1 tethered jailbreak, bought Apple’s $29 iPad Dock Connector to VGA Adapter, and installed Ryan Petrich’s $2 Display Out on his iPad in order to project the screen display for the iPad Supersession. He has provided detailed instructions on how to do the entire set-up.

But the question is, Why Breen chose to jailbreak? Well, if Apple could have provided the functionality to display an iOS device’s entire interface, teachers and presenters like Christopher Breen will hardly chose to jailbreak their iPad. Don’t you agree? What do you say? Please share your valuable suggestions via comment section below.

Greenpois0n iOS 4.2.1 OOB Jailbreak to Support all Devices [CONFIRMED]

iPhone hacker Pod2g of Chronic Dev Team has confirmed that the updated Greenpois0n tool will untether jailbreak iPhone 4, iPhone 3GS, iPod touch 3G, iPod Touch 4G and iPad running iOS 4.2.1 OOB without requiring SHSH blobs for iOS 4.2b3.

About the 4.2.1. OOB jailbreak : it will be for all devices supported by gp at that time.

Few days back, the Joshu Hill of Chronic Dev Team posted a teaser video showing untethered iOS 4.2.1 Jailbreak running on iPhone 4. Interestingly, last week pod2g of SHAtter jailbreak exploit fame discovered another exploit for untethered jailbreakfor iPhone, iPad, iPod touch running on iOS 4.2.1. But most likely it will be used in a new tool to jailbreak iOS 4.3+ or iOS 5.0.

Geohot to Release Untethered iOS 4.2.1 Jailbreak ?

The most vocal member of iPhone Dev Team Musclenerd is confirming that Geohot is already having working untethered iOS 4.2.1 jailbreak solution which may not be working for all idevices. When iPodguy79 tweeted:

@sherif_hashim @MuscleNerd @iphone_dev @chpwn keep up with your soap opera and geo will be slapping another reality check on you

Musclenerd Replied: @ipodguy79 I hear geohot does have an untether actually! Though not for all devices.

On the other hand, iPhone Dev Team is still ironing out  bugs that are lurking the final release of redsn0w 0.9.7 which support untethered jailbreak. Comex’s upcoming untethered jailbreak for iOS 4.2.1 is probably going to be a Cydia package over your existing Redsn0w tethered jailbreak but no ETA has been cited so far!

While we’re not sure about the status of that window, we do know that the untethered jailbreak software will be released very soon. We’ll keep you updated as soon as more information pours in.

Save iOS 4.2.1 IPSW File and SHSH if You Want Untethered Jailbreak on iOS 4.3 for All iDevcies

Three weeks ago, we told you about the untethered jailbreak from Comex on iOS 4.2.1 for all iDevices which was scheduled to release by Christmas, but due to some issues Comex was not able to finish his job. So the iPhone Dev-Team had an alternative plan which is the “back up plan” using an old firmware iOS 4.2b3, but this firmware caused some piracy issues, as it’s not available for public, it’s only available for developers.

L0ung3f1Y asking: @comex or freakin release a jailbreak that does not require 4.2b3
MuscleNerd replying: So if @comex were to develop 4.2.1 untether, we warn all to save their 4.2.1 IPSWs for 4.3 untether via Monte

So, if Comex releases the untethered jailbreak for iOS 4.2.1 then you will need to preserve your iOS 4.2.1 IPSW and hashes to be able to get untethered jailbreak for the upcoming iOS 4.3

More explanation ? iOS 4.2.1 Redsn0w jailbreak is based on Limera1n bootrom exploit by Geohot, but this exploit can’t make untethered jailbreak itself, it needs some help to make untethered jailbreak which is a kernel hack, This is precisely what Comex wants to get.

While we are able to jailbreak all our iOS devices using Redsn0w 0.9.7, the dev-team may preserve the new Comex‘s kernel hack to untethered jailbreak all upcoming iOS for all iDevices, so you have to save the iOS 4.2.1 IPSW file and its hashes to enjoy untethered jailbreak as long as possible.

Sn0wbreeze for iOS 4.2.1, Including iBooty 2.0 Coming Soon

We have been tipped off over twitter that iH8sn0w, a 15
years old guy behind Sn0wbreeze, f0recase, iREB and iBooty, is
working on iBooty 2.0 which will bring “1 click tethered boot” on
iOS 4.2.1. Currently, iBooty 2.0 is being tested out by certain
iPhone users and after getting positive feedback we can expect the
release of Sn0wbreeze 2.2 for iOS 4.2.1 in next few days. The
Pirate who is also testing iBooty 2.0 has just confirmed the same
on his twitter account:

For those iPhone
users who don’t know, Sn0wbreeze tool is used to cook custom
firmware for iDevices on Windows Operating System. The current
Snowbreeze 2.1 version supports up to iOS 4.1 firmware on iPhone
and iPod Touch and iOS 3.2.2 on iPad. For Mac users PwnageTool with
iOS 4.2.1 support is already available.
