this error? My iPhone is dead. Please help, I’m a novice. Thanks in advance.Asked by: Patrick from Jersey City, New Jersey Hello Patrick, iTunes Error 21 occurs during the custom IPSW firmware using the recovery mode instead of the traditional DFU mode or Device Firmware Upgrade mode. So there’s a possibility that you may encounter Error 21 when you use PwnageTool or Sn0wbreeze jailbreak tools since these tools were used to create custom pre-jailbroken IPSW file, but chances to get error 21 is very low. By the way, are you planning to unlock your iPhone? Why do you have to use Sn0wbreeze or PwnageTool to restore a custom firmware? If you don’t care about unlocking your iPhone from AT&T then you can just jailbreak your iPhone 4 using Redsn0w 0.9.6rc12 on iOS 4.2.1 or Redsn0w 0.9.6Rrc16 on iOS 4.3.3.Anyway, to fix iTunes’ Error 21, you must put your iPhone (iPad or iPod Touch) into DFU mode. If you don’t know how to put your iOS device into DFU mode, then you can follow the step by step guide posted below:Step 1: Connect your
