What Are The Difference Between DFU and Recovery Mode

This tutorial tells you the basic difference between iPhone’s DFU and Recovery modes and what mode is used for what purpose. If you already know the difference between the two modes and looking for just the instructions on how to put iPhone into the two modes read:

Difference Between DFU and Recovery Mode:

What are these modes for and why should I know about them?

If you are a new iPhone user or don’t care about jailbreaking chances are that you might have never come across these two modes and won’t need to in the future either. But if you use Cydia or custom IPSW firmware on your iPhone or other iOS devices you will definitely come across this.

DFU stands for Device Firmware Update. Both of the modes can be entered by pressing a particular series of buttons on your iPhone. They help you update or install firmware when the normal iTunes method fails. Here are some situations when you might need to use these modes.

  • Reset iPhone if your forgot Passcode
  • Downgrade Firmware version
  • Install beta iOS Firmware
  • When iTunes returns errors like 1013, 1603 etc.

iPhone Recovery mode vs DFU mode:

iPhone Recovery Mode:

Recovery Mode boots your iPhone and stops at the Connect to iTunes screen. You can use it to install the latest firmware but not downgrade. You can click on Restore in iTunes to let iTunes download firmware and install. Alternatively, you can download firmware from here and press Alt + Restore(Shift + Restore on Windows) to browse for firmware manually.

iPhone Recovery Mode

The recovery mode and iTunes will prevent you from restoring to older firmware than the current firmware. You will keep getting error in iTunes every time you try doing it. This is because iPhone has already booted and knows the current firmware version.

iPhone DFU Mode:

DFU mode on the other hand does not fully start up the iPhone or iPod Touch. The screen remains off and appears as if your iPhone is turned off but it will be recognized in iTunes and be ready for restoring to any firmware. Since, the firmware is not booted you can downgrade iPhone to previous versions or even custom firmwares with Cydia and other packages created from jailbreak tools like PwnageTool.

iOS 5 Beta 2: Wi-Fi Sync, OTA Updates and Wireless Recovery Mode

Apple released iOS 5 beta 2 yesterday and since then lot of things have been proved, such as it still can be jailbroken and that the Gevey SIM mole has been dealt with. There are also few new features in the new beta, but it’s best we wait until proper testing is done and then know what all the new features are. For now let’s just discuss the main three. The latest update of iOS 5 beta 2 brings along the much awaited Wi-Fi sync, OTA updates and the wireless recovery mode, hence making transfer of files, software updates and entering DFU mode much easier.

iOS 5

Seems like Apple is slowly adding new features with new beta releases and not all the 200 at once. There are few other features that we have already discussed, some minor ones and there will be more to come.



Wireless Syncing


We’ve all been waiting for this, the ability to sync our iPhone, iPod Touch and iPad without the need of any cables. Just connect to your Wi-Fi network and select Wi-Fi sync in iTunes and you’re ready to bounce. However, at the moment this only works for Mac users and you’ll need to be running on Mac OS X 10.6.8 or Lion developer versions and iTunes 10.5 beta 2 to try this. You can sync all your data including music, videos and applications, even from your iCloud account.

Over the Air Updates

OTA Updates

As promised, iOS 5 will see over the air updates for all new software updates and patches. 9to5 Mac also noticed that OTA updates may also work over a 3G connection, but apparently it’s not happening with the beta 2 build.

Wireless syncing is triggered automatically when the device is connected to power and on the same network as the paired computer. Or, you can manually trigger a sync from iTunes or from Settings -> General -> iTunes Sync (same network as paired computer required). Be sure your device is plugged into a power source when performing Wireless syncs.

Wireless Recovery  Mode

Wireless Recovery Mode

With the latest beta of iOS 5, you can also enter right into Recovery mode without having to go through all the trouble of playing mind games with your fingers. It’s way simpler. Again, 9to5 Mac reported that they achieved this by using Recboot for Mac.

Do let us know if you’ve had any success or have tried iOS 5 beta 2 on your Apple device.
