If you’re like me who eventually forget passcodes and passwords, you may have been in a situation where you confidently changed your password and you cant seem to remember what is it.

here’s the steps.

1. Prepare a custom iPhone RAM disk. There are numerous How-To’s out there to do this. Your custom RAM disk will need to mount /dev/rdisk0s2 (say, /mnt) and simply delete the file /mnt/mobile/Library/Preferences/com.apple.springboard.plist. This is the config file that tells springboard “passcode: on”
2. Use the iPhone Utility Client to place the device into recovery mode and then boot the RAM disk using something like:

   (iPHUC Recovery) #: filecopytophone Bypass_Passcode.bin

   filecopytophone: 0

   (iPHUC Recovery) #: cmd setenv\ boot-args\ rd=md0\ -x\ -s\ pmd0=0×9340000.0xA00000

   (iPHUC Recovery) #: cmd saveenv

   (iPHUC Recovery) #: cmd bootx

3. After your custom RAM disk blows away the springboard config, reboot the phone and the passcode will be circumvented, because SpringBoard’s default is “no passcode”

If you’re savvy enough and have knowledge of iphone hacking tools and stuff, you can try it but if you’re lazy or just too busy like me i’ll just open up itunes and hit “restore” this will restore everything and you can now use your iphone.
