DFU mode is a very powerful fix for most issues with your Apple device. However, it is confusing when your device enters DFU mode on its own.
Before you put your device into DFU mode, it is best to go through this guide and figure out whether the DFU mode will delete data on your iPhone.
What Is DFU Mode Used For?
The DFU mode is not something you would want to apply to your phone every day. Even if you run into some issues with your phone, the Recovery Mode fixes them just fine.
So in some situations, you may need the DFU mode, like the following:
- If you want to downgrade your operating system on the device. This is because a new update often causes glitches on a device and some people want to return their device to older settings. It is not advised in general but can become crucial if Apple leaves your phone useless after a new OS update.
- To jailbreak or un-jailbreak your device
- If you want to move on from the beta version of any device
- Fix your iPhone that is stuck on the Apple logo
You should be aware that it is risky to put your phone in DFU mode because you may end up losing some data or leave some files to get corrupted.
If you use the DFU mode for jailbreaking or un-jailbreaking your phone, you will end up violating the device’s warranty.
Does DFU Mode Delete Data on iPhone?
When using DFU mode to change the OS on your device or fix any other problem, there is always a risk of losing your data.
It is a similar method to iTunes restore and will delete all your device data and get your device back to its original state.
The photos, videos, and other app settings on your phone will be lost, and when you are finished, you need to restore the device from a previous backup to avoid data loss.
For this reason, we recommend that you keep your data backed up so it is easy to set up the phone once the problem is solved.
