Differences Between DFU Mode and Recovery Mode

DFU Mode and Recovery Mode are known as a failsafe to reflash iPhone, iPad or iPod touch for

users. Actually, the two modes can do much more than that. We need to complete the operation

like update iOS with the DFU Mode or Recovery Mode. In a certain aspect, they are very similar

and people may get confused in the concepts. Now I want to talk about the DFU Mode and

Recovery Mode in a more comprehensive way.

Part 1: What Are DFU Mode and Recovery Mode Used for?

Users always enter Recovery mode to upgrade iOS or solve the system problems. With Recovery

mode, You can fix some system problems including:

1. iOS device get stuck in white Apple logo screen or black/blue screen and can not enter the

system.

2. iOS device get restart again and again.

DFU mode is a state that you can make changes to the iOS system without booting your iPhone,

iPad or iPod touch. With DFU mode, you can fix the system problems of your device that could

not be solved with Recovery mode. It is more comprehensive when compared with Recovery

mode.

Besides, you can enter DFU mode to upgrade or downgrade your device. Often, we would

upgrade our iOS for more functions or better use. But sometimes we would want to downgrade it

because with the new version, the system or the software on our device could not fit it well.

Note: If you want to downgrade your device, you need to use DFU mode but not Recovery

mode. The reason would be shown in the second part, please continue to read.

What's more, some users would use DFU mode to make iPhone jailbroken or SIM unlock.

Part 2: Differences Between DFU Mode and Recovery Mode

While both DFU mode and Recovery mode can solve some system problems, you may ask what

the difference between them is. The answer would be iBoot.

iBoot is also named iBoot Loader or iBoot Agent. Just like the meaning of its name, iBoot act as

the guide agent between the iPhone hardware and iOS. Recovery mode needs to use iBoot

during the operation while DFU mode skips iBoot. In recovery mode, iBoot would detect the

firmware that flashed in and compare it with the current one. If the flashed one is lower than the

original version, iBoot will refuse to carry over the subsequent instruction and it would fail to

update the iOS. And that is the reason why we need to enter the DFU mode to downgrade iOS

instead of Recovery mode.

For Recovery mode, you can upgrade or restore your iPhone, which requires the latest iOS and

firmware. Because of the iBoot, it is not allowed to choose a custom firmware or choose the one

you want in Recovery mode.

But for DFU mode, you can not only upgrade your iPhone, iPad or iPod touch, but also

downgrade the firmware or choose a custom one for jailbreak or SIM unlock.
