Here’s how I got the iPhone into Recovery mode to do an official Apple restore: To load the iPhone with the official Apple image, I had to put it into Recovery mode. I decided to load the latest official Apple iOS 4.2.1 image onto the iPhone and then use RedSn0w to jailbreak it. Unfortunately, the custom image restore process failed midway. I then attempted to jailbreak using the custom PwnageTool firmware image I created in (my nephew’s iPhone 3G is the same model as mine’s). I found that I could put the iPhone into Recovery mode.
Unfortunately, the iPhone was stuck in a weird state with only the Apple logo showing, and the iTunes application did not recognize it. DecemMy nephew got an iPhone 3G and wanted to unlock it for use with his T-Mobile plan.
