For $7, I was able to have my iPhone’s UUID added to a developers account to enable me to download and install beta 4 of OS4 for the iPhone. It seems pretty neat, but rather uninspiring- especially since there are no available jailbreaks for OS4 beta on a 3GS (only on a 3G).
Luckily I came upon an article at MacLife that provides a solution for this…
Note: this can only be done on OS X. The article has links for 10.6, but I was albe to find the 10.5 LibUSB package.
Step 1: Download the following:
Install the LibUSB and extract iRecovery to a place where you can access it (such as the desktop).
- Power off your iPhone
- Hold down the ‘Home’ button and plug in the USB cable to your Mac; this will put the iPhone into recovery mode
- iTunes will inform you that your iPhone is in recovery mode and must be Restored.
- Run an iPhone restore in iTunes as you normally would.
- The recovery will run for a few minutes and then fail with ‘An Unknown Error has Occurred: 1015’
Step 3: iRecovery
- With the iPhone still plugged in, open a terminal (Applications, Utilities, Terminal) and navigate to the location where you extracted iRecovery (cd Desktop).
- Enter the following commands, pressing return between each:
setenv auto-boot true
The command prompt will return after a few seconds; you can now reboot your iPhone (hold Home + Power for a few seconds).
After you power back on, you should be able to connect to iTunes and re-activate (and run Spirit to Jailbreak).
