When trying to restore my iPhone with iTunes and firmware 2.0, iTunes continuously shows a message that stops the restore process, it was probably related to basehand update, but I ain’t sure about this. After some headaches here is the solution.
Downgrade to 1.1.4
- Step 1) The first problem in your downgrade is that you probably are getting error 20 in restore mode and error 160x in DFU mode. This is due to iTunes 7.7. So, you now you need to uninstall iTunes 7.7 and install iTunes 7.5.
Load up Terminal and type the following:
- Step 2) Now that you have iTunes 7.5, you will still have the DFU driver for 7.7. This is good and will allow the process to work. Put your phone into DFU mode using the DFU steps. You will not have any display on your device in DFU mode. If you see the cable and connect to iTunes, you did not get into DFU mode.
- Step 3) Restore using iTunes 7.5. and 1.1.4 firmware, it will work after all.
Now you have an unlocked 1.1.4 iphone, you can choose between upgrade to 2.0 with pwnage or unlock it with ziphone, again … up to you.
