Jailbreaking/unlocking the 1st generation iPhone using redsn0w

Page 2 of 2


If you chose unlock, then you must provide the boot loader files to redsn0w. Click the browse button for the 3.9 boot loader.





Navigate to the boot loader file, select it and click Open.




Click the browse button for the 4.6 boot loader.




Navigate to the boot loader file, select it and click Open.




Click Next.




Make sure your iPhone is off, and plugged into your computer with the USB cable. Click the Next button.




Instructions for entering DFU mode will appear. They start right away and go very quickly so try to keep up! First hold down the Power (sleep/wake) button for three seconds.






Keep holding on to the Power button, and press and hold the Home button for 10 seconds.




Continue holding the Home button, and release the Power button.




After a few seconds various messages will appear on the screen. At this point you can let go of the Home button.

Note: If your redsn0w screen hangs at the message Waiting for reboot, then simply unplug the USB cable, then plug it back in.




You will see this graphic on your iPhone.




After a bit the iPhone will reboot (and if you chose a custom boot logo it will appear at this point). Done! will appear in the program. You can click the Finish button to close the program.




You will see a few different messages (Installing base utilities, Replacing kernel, Flashing NOR, Installing bundles, Activating, Syncing file systems, Rebooting) on your iPhone during the next couple minutes.




The iPhone will reboot. Then BootNeuter will run.

If your iPhone was previously unlocked, and you didn't know, no problem. BootNeuter would quickly detect that there was nothing for it to do, and it will display the four images below.

If you were not already unlocked, you will see these screens right after the iPhone reboots. These are the status screens you will see:

Step 5.

The iPhone will reboot again. iTunes should ask you to set up your iPhone. Note: Many people find that they have problems with their applications crashing, and have battery usage issues when they choose "Restore from the backup of" at this screen. If this happens to you, your only option may be to repeat this entire process then choose "Set up as a new iPhone" and resync your iPhone instead. You will of course lose application specific data.




iTunes will now confirm you are on 3.1.2 firmware.




Cydia has been added to my SpringBoard.




If you launch Settings, and press, General, About, you can confirm your firmware versions here. Note: I always erase my Serial Number, Wi-Fi Address, Bluetooth, IMEI and ICCID from my screen shots for privacy reasons.
