Hack the iPhone

I highly recommend not using this method and instead use the simple method found here. The results are the same and will save you 1 hour and 40 minutes of effort.

How to unlock 1.1.3 firmware with the 4.6 bootloader

(intel Mac)

(Page 1 of 5)




If you ever wanted an unlocked iPhone, then now is the time to get one. As of this writing (February 10, 2008), every single iPhone in an Apple or AT&T store is fully unlockable! Get 'em while they last.

If it wasn't for GeoHot this would not be possible. You can visit (and donate) to him via his website here.

Note: other guides out there have you run GeoHot's new unlocking program while you are on 1.1.1 firmware. This will result in having a phone signal when you get to 1.1.2 firmware. My tutorial does not do that. I instead have you run the unlocking program when you are on 1.1.2 firmware. The difference is you won't have a phone signal until after you have soft upgraded to 1.1.3 firmware. Either method works, just follow the directions carefully.

Attention

You should read my Warning to all iPhone owners page before proceeding.

Step 1.

If you aren't sure your brand new shiny iPhone is on 1.1.3 firmware there is an easy way to check. You should do this if in doubt since you can't use the unlock method I will use in this guide on iPhones with the 3.9 bootloader. Turn on the iPhone. You'll be at the slide for emergency screen, so slide. At the keypad dial *3001#12345#* then press the green phone button.




Press Versions. If you see 04.03.13_G, then you have a 1.1.3 iPhone. Press the Home button.

Step 2.

Plug the iPhone into your computer. Launch iTunes. You should see the Welcome to your new iPhone screen.




Put the iPhone into DFU mode. Do this by pressing and holding both the Sleep/Wake button and the Home button for 10 seconds. At this point the screen will turn black, and the iPhone will appear to be off.




Let go of the Sleep/Wake button and continue to hold the Home button. In approximately 10 seconds iTunes will give an alert sound and a pop up will appear announcing that it has detected an iPhone in recovery mode. Dismiss this pop up.




iTunes will display this screen now.




Now press the Option key on your keyboard and click the Restore button. A file browser window will open. Point it to where you have the 1.1.1 firmware file downloaded to your computer already. Select the .ipsw file and click Open. Note: if you do not have this firmware file downloaded already, then click here to download it.




Various messages will appear throughout the restore process.




When it has completed you will get a pop up indicating error 1015. You will also get the graphic of a cable pointing to the iTunes icon on the iPhone.




You'll now get a pop up about recovery mode. Dismiss it.




Eject the iPhone from iTunes and then close iTunes.







Also open Activity Monitor and ensure that iTunes Helper is not running. To do this, go to your Mac's Applications folder, then into the Utilities folder, and you'll find a program called Activity Monitor here. Launch it. At the top there is a drop down box. Make sure My Processes is selected. Now look below for iTunes Helper. Select it and click on Quit Process at the top.




At the pop up that appears, select Force Quit. You can close Activity Monitor now. iTunes Helper will not respawn until your computer is restarted.

Step 3.

Launch iNdependence. You can download it here. If the program doesn't do anything after 60 seconds and displays this same status bar message, then you need to follow the above instructions and restore to 1.1.1 firmware again.

This is a common problem when downgrading 1.1.3 firmware.




If you restored again, then launch iNdependence again. This time you should get a spinning wheel in the lower status bar of the program and it should say: Disconnected: waiting for iPhone... The iPhone should chirp and display the activation screen. You will have a new message in the status bar of iNdependence now. Close iNdependence.
