PwnageTool Bundle for Jailbreaking iOS 4.3 Beta on iPhone 4 Released!



Renowned PwnageTool bundle creator Msftguy is back with his latest release i.e a PwnageTool bundle for jailbreaking iOS 4.3 Beta 1 on iPhone 4. However, the process is quite complex and is aimed for advanced users only as it requires you to create a ramdisk in order to achieve the jailbreak. In addition, you must also be enrolled in either iPhone Developer Standard or Enterprise Program and most importantly, own a computer running Mac OS.

Step 6:

Create your own ramdisk using the following steps: (source)

Tools needed: OS X, xpwntool

Unpack the original ramdisk: xpwntool orig_restore_rd.dmg restore_rd.dec.dmg -iv .. -k .. (use the keys from wiki)

Mount the ramdisk: hdiutil attach restore_rd.dec.dmg

Free up some space: rm /Volumes/ramdisk/(some unneeded large-ish file)

Patch asr: mv /Volumes/ramdisk/usr/sbin/asr /tmp/; bspatch /tmp/asr /Volumes/ramdisk/usr/sbin/asr (bundle_path)/asr.patch

Change the restore options: edit /Volumes/ramdisk/usr/local/share/restore/options.plist with Property List Editor, add ‘UpdateBaseband’ = false – see https://theiphonewiki.com/wiki/index.php?title=Preventing_Baseband_Update for details

Unmount the ramdisk: hdiutil detach /Volumes/ramdisk

Re-encrypt the ramdisk: xpwntool restore_rd.dec.dmg pwned_restore_rd.dmg -t orig_restore_rd.dmg -iv .. -k ..

Replace the ramdisk inside of CFW produced by the Pwnage Tool with pwned_restore_rd.dmg You can either unzip and re-zip the CFW or replace it inside of /tmp/ipsw dir when PwnageTool is running.
