Fix Error 21
Facebook Share on LinkedIn Hello Jaxov, need help here. Few days back, I am trying to jailbreak my iPhone 4 on iOS 4.2.1 using Sn0wbreeze 2.5.1, but during the custom firmware restoration process, iTunes throws Error 21.
Error 21 Ipad
This is a used iPhone 4 and it was jailbroken on iOS 4.3.1 using PwnageTool but the previous user said he did not encounter this error. What do I need to do to fix 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 apple error 11 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 iPhone (iPad or iPod Touch) to your Mac or PC via USB cable (USB cable) and then launch iTunes.Step 2: Then hold down the Home and Power button at the same time for 10 seconds.Step 3: Release the Power button after 10 seconds but continue holding the Home button and wait for iTunes to detect your iPhone in recovery mode.Step 4: Once your iPhone (iPad or iPod Touch) is in DFU mode, you should see nothing on its screen. It should be completely blank.That’

(18 May '11, 16:39) mrchic Redsn0w won't touch the baseband unless you tell it to install the iPad baseband. You can restore to stock 4.3.3 while preserving your baseband by running TinyUmbrella's TSS server, but that only works with iPhone 4.
