If you are currently Jailbroken on the official iOS 5 firmware you have a tethered Jailbreak (only old bootrom iPhone 3GS users have an untethered iOS 5 Jailbreak). A tethered Jailbreak means that if your iPhone, iPod Touch or iPad loses power (either battery dies or it crashes) you will need to plug your iDevice back into your computer and use RedSn0w to re-boot it into a usable state.
A tethered Jailbreak is never ideal. Even though the iOS 5 firmware is very stable there is always that one off time where your iPhone, iPod Touch or iPad crashes or loses power while you are away from my computer and this becomes a very big problem. You can no longer use your iDevice; even in an emergency.
BigBoss has realized that with so many people running the iOS 5 firmware with a tethered Jailbroken. It would very much come in handy to have a Semitethered Jailbreak option available for those who cannot possibly be without their Apple device while they are away from a computer. Thus, Bigboss has developed a beta Semitethered Jailbreak package that is installed from Cydia to Jailbreak the iPhone, iPod Touch and iPad running the iOS 5 firmware Semitethered.
Note: The Semitethered iOS 5 Jailbreak is still in beta. Expect errors.
What Is A Semitethered Jailbreak?
For a lot of people the idea of a Semitethered Jailbreak is very much a new concept. A Semitethered Jailbreak means that if your iPhone, iPod Touch or iPad loses power (and it is Jailbroken tethered) it will re-boot into a semi-functioning state where you can use essential apps such as the Phone.app and SMS.app. BigBoss has put together an official list of which functions will work on your iDevice if it re-boots into a Semitethered state:
Can use phone, sms (text messages) Can use every other stock app on iphone. Cannot use mobile safari Can use other appstore web browsers such as atomic web browser Cannot use mail app. You could install a gmail app from appstore or such instead. You cannot use any jailbreak tweak, app, cydia until you boot tethered. While in the semitether booted state, you should not add a jailbreak ios5 notification such as sbsettings to notifications during this state or your device will be stuck in a respring loop until you get home to “boot tethered”.
It is important to keep in mind that the iOS 5 Semitethered Jailbreak also carries with it the following:
The device will take longer to boot up. When you reboot, it has to reload every service. It will respring a couple times also. According to Saurik, there are some “problems” to reloading all daemons on the fly. This is why mobile substrate installation requires “reboot device” in cydia. I have not experienced any of these problems, but I am not promising they do not exist. This is why we will need testing to see which problems may occur. Is a Semitethered Jailbreak worth it?
In my opinion the iOS 5 semitethered Jailbreaking solution is definitely worth it if you need to have a functioning Apple device with you at all times. As BigBoss says “The good, by far, outweighs the bad for this iOS 5 semitethered Jailbreak”. When you have your iPhone, iPod Touch or iPad Jailbroken on the iOS 5 firmware with a Semitethered Jailbreak you will only have these limitations laid out above if your iDevice loses power. These limitations are once again gone after you connect your iDevice to your computer and use RedSn0w to boot it into a working state.
Download iOS 5 Semitethered Jailbreak
The great news about this Semitethered Jailbreak is that you do not need to re-run a Jailbreaking tool over your existing Jailbreak. To install the iOS 5 Semitethered Jailbreak on your iPhone, iPod Touch or iPad you will simply need to add the following source through Cydia:
After adding the Cydia repo above you will simply need to download and install the iOS Semitethered package on your iPhone, iPod Touch or iPad.
Note #1: When you install the Semitethered Jailbreak package you will have to reboot your iDevice, so make sure you are prepared at a computer to reboot tethered with redsn0w or just “home button out” of Cydia and manually respring until you get home.
Note #2: Please email any error reports to BigBoss and use the subject: “Cydia/APT(A): semitether”.
This iOS 5 Semitethered Jailbreak solution if perfect for all of those worried about not being able to use their iPhone, iPod Touch or iPad while it has a tethered Jailbreak. We will provide a How To guide for Jailbreaking your iDevice Semitethered running the iOS 5 firmware in the near future. Please share any questions or thoughts in the comments section below…
Apple has released new iOS 4.3.5 today. this is just the minnor update which patches a apple server certificate verification issue. Today we will show you how to jailbreak iPad (1st generation) running iOS 4.3.5 by using the existing version of Redsn0w 0.9.8 made by Dev team hackers. The redsn0w iPad jailbreak however is tethered at the moment. But hacker are working hard to bring it to untethered mode right now.
iOS 4.3.5 was recently released by Apple and you might be winteresting what is the best soft to use for iPhone or iPad jailbreak. The Dev Team hacker have made custom PwnageTool 4.3.5 bundle which allows iDevice fans who really want take care on carrier unlock to jailbreak iOS 4.3.5 on iPhone 4.
Why to use PwnageTool 4.3.5 over Redsn0w 0.9.8 b3 version which is beta now for 4.3.5 iOS jailbreak? I think by using this method of iDevice jailbreak, you’ll be able to preserve your old 1.59.00 iPhone baseband which could be unlocked with Ultrasn0w, the only software method of iPhone unlocking, provided by Geohot and other dev Team members.
Picture: Cydia running on iOS 4.3.5, iPhone 4 (GSM)
To perform iOS 4.3.5 tethered jailbreak using PwnageTool v4.3.5, you have to download the following files:
Important Note: There is currently no unlock for iPhone 4 on 4.10.01 baseband of iOS 4.3.5. If you are care of software carrier unlock, do NOT update to the stock 4.3.5 from iTunes.
How to Modify PwnageTool For Custom Bundle
Step 1: extract the custom bundle we mentioned above and drag it to your desktop.
Step 2: drag the PwnageTool app to the /Applications folder but do not launch it yet. Instead, right-click it and select Show Package Contents, in order to insert the bundle. For reference, check out the screenshot below.
Step 3: you should now see a Finder window identical to the one below. Navigate over to Contents/Resources/FirmwareBundles/ and place the .bundle file you had selected earlier to this location, then close the window.
Creating Custom 4.3.5 Firmware
Step 4: start up PwnageTool in Expert mode, as shown on the screenshot below. Select the device you’re using, then click on the blue arrow on the bottom-right corner of the window to proceed.
Step 5: when requested, point PwnageTool to the iOS 4.3.5 IPSW file you downloaded earlier, as shown in the screenshot below.
Step 6: on the next screen, you’ll be given the option to further customize the software you’re about to build. Feel free to toy around with these settings, but only if you know what you’re doing. If you’re not sure what to do, just click on “Build” as shown below. PwnageTool will then build a jailbroken firmware, a process that could take a few minutes, so kick back and have a soda.
Step 7: when instructed, you need to put your phone into DFU mode. Just do as follows:
Hold down both the Power and Home buttons simultaneously for 10 seconds. Release the Power button but keep holding the Home button for 10 more seconds. If your screen is black, you’re in DFU mode. If an iTunes logo is displayed, you’re in Restore Mode: just try the steps above a few more times, sometimes it doesn’t go well on the first try. Nonetheless, a notification will be displayed if you’ve managed to enter this mode correctly.
Restoring Custom iOS 4.3.5 Firmware On iPhone 4
Step 8: once this process is done, you’re free to exit out of PwnageTool. Now launch iTunes and restore to the firmware file you’ve just created: select your device from the iTunes sidebar, and click Restore while holding down the Alt key on your keyboard. Select the firmware file you’ve just saved (make sure it’s the one created by PwnageTool, not the default firmware) and click Open. iTunes should now begin loading the jailbroken firmware to your device, avoid interacting it at this point. If everything goes as expecting, your device should be jailbroken at this point.
Booting iPhone In Tethered Mode
Since this is a tethered jailbreak, whenever you boot up your device you’ll have to plug it into your computer and run a small utility known as tetheredboot. You’ll need to follow the following Step 11 and Step 12 whenever you start up your device!
Step 9: place tetheredboot (download link at the beginning of the article) in an accessible directory.
Step 10: change the extension of the custom IPSW file you’ve just created to .zip by renaming the file, then extract it much like a real ZIP file. Navigate to /Firmware/dfu/ and copy two files (kernelcache.release.n90 and iBSS.n90ap.RELEASE.dfu) from that directory to the folder you’ve pasted tetheredboot utility into, as shown below.
Step 11: with your device plugged in but turned off, bring up the Mac OS X Terminal (by heading to Applications/Utilities/Terminal), type in the following commend, press enter and insert your password when requested:
Important: Make sure you replace /Users/TaimurAsad/Desktop/tetheredboot/ with the directory where you have placed the tetheredboot utility.
If you’re not comfortable typing in commands, you can simply drag the 3 files in your tetheredboot folder right into the terminal window after the original sudo -s command.
Step 12: after some code runs through the terminal, you’ll be asked to set your phone into DFU mode. Do so, as shown below:
Hold down both the Power and Home buttons simultaneously for 10 seconds. Release the Power button but keep holding the Home button for 10 more seconds. If your screen is black, you’re in DFU mode. If an iTunes logo is displayed, you’re in Restore Mode: just try the steps above a few more times, sometimes it doesn’t go well on the first try.
If you wait a few seconds, you should see “Exiting libpois0n” on the terminal. Your device is now in a jailbroken state until next time you power off.
