How to Downgrade your iPhone 2.0 to 1.14 [Updated]
This is a great guide on how to downgrade your iPhone from 2.0 to 1.1.4. Here’s a step by step guide written by _X_ for anyone whose looking to downgrade from 2.0 to 1.14!
Requirements (With Download Links):
iTunes 7.5 (You don’t need iTunes 7.7 for this)
iLiberty+Windows / Mac Version
iPhone1,1_1.1.4_4A102_Restore.ipsw firmware -
KiPhone Windows / Mac (Patched version of ZiPhone) -
(Update: More KiPhone Download Links - Download for Windows - Download for MAC OS X)
Step 1:
Uninstall iTunes 7.7 if you have it and restart your computer
Step 2:
Install iTunes 7.5, iLiberty+ & KiPhone. Make sure only iTunes is running.
Step 3:
Your iPhone should be in 2 states, either stuck on the “Slide to make emergency calls” screen, or you tried to restore before and it’s stuck on the new look “connect to iTunes” screen. Either way, it’s fine.
Enter the phone in DFU mode (You must have the iPhone connected to the computer and iTunes running). To do this, hold the power & the home button down for 9 seconds.
Why 9? Well people say 10, but it depends how slow you are at counting. Too short and it doesn’t work, too long and the apple logo appears.
When you hit about 6/7 the screen should turn off, leave it for 2 more seconds and release the power button, STILL holding the home button. If all went well, you should NOT see an apple logo, the screen should be dead. Keep holding home until windows/Mac informs you that it’s found new hardware, OR iTunes tells you that your iPhone is in recovery mode. Remember, screen should be blank.
If you see an apple logo, repeat the process for less time until you get it right. Took me a little time.
