How to Jailbreak iOS 4.3.5 on iPhone 4, iPad, iPod touch using PwnageTool 4.3.5
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.

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:
Then type in the following:
/Users/TaimurAsad/Desktop/tetheredboot/tetheredboot /Users/TaimurAsad/Desktop/tetheredboot/iBSS.n90ap.RELEASE.dfu /Users/TaimurAsad/Desktop/tetheredboot/kernelcache.release.n90
if the commands above don’t work, try the following:
/Users/TaimurAsad/Desktop/tetheredboot/tetheredboot –i /Users/TaimurAsad/Desktop/tetheredboot/iBSS.n90ap.RELEASE.dfu -k /Users/TaimurAsad/Desktop/tetheredboot/kernelcache.release.n90
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.
