Apple devices keep malfunctioning from time to time due to numerous reasons. Sometimes a software update goes wrong or the device gets stuck in a mode or on the infamous iPhone black screen. Some of the most common iOS issues include iPhone DFU mode and iPhone error 3194. Let’s have a closer look at what these problems are and their possible solutions.
iPhone DFU Mode
The DFU in iPhone DFU Mode is an acronym that stands for Device Firmware Update. iPhone users enter this mode to either fix iOS system updates on their device or to jailbreak it. In the first case, most iPhone users enter the DFU mode to upgrade/downgrade their device’s firmware without entering the recovery mode. In the second case, people enter DFU mode to unlock their SIM cards, get locked by entering the wrong pin code.
The reason why iPhone users might want to use a downgraded version of iOS varies from person to person, whereas the reason why people might want to jailbreak into their device is for getting access back to their device.
When iPhone users enter their device’s DFU mode, they aren’t able to exit it often. When a device gets stuck in its firmware update mode, it is probably because one of the following reasons:
- Software glitch
- Hardware damage
Regardless of the reason for being stuck in the iPhone DFU mode, the following methods can be used to get exit it.
Since iTunes is the official iOS system repair tool, the first method to get out of DFU mode is by taking its help and following the following steps:
- Launch iTunes on your computer/laptop or any other device
- Connect your device; iPhone/iPad, and the computer through a USB.
- Once you have established a connection, quickly press the ‘Home’ button, and release it.
- Press and hold the ‘Power/Sleep’ button for at least 10 seconds.
This should get your device out of its DFU mode and restore it to its normal mode.
Reboot Your Device
The second method to rescue someone stuck in iPhone DFU Mode is by asking them to reboot their device. The reboot method requires the iPhone user to enter the recovery mode by pressing and holding the ‘Power’ and ‘Home’ button simultaneously for a while. Once the device enters the recovery mode, the users can hit on the reboot option with the help of their ‘Home’ button. However, before hitting reboot, make sure the device is connected to iTunes via any other PC.
The reboot method works for most users stuck in the iPhone DFU mode. However, if this option doesn’t work for your device, then you might need other solutions.

iPhone Error 3194
iPhone error 3194 is a common problem faced by Apple users. This occurs when a user is trying to update their iOS using iTunes, but the iTunes platform is unable to make a connection with Apple’s software update servers.
Generally, the conflict between the iTunes platform and Apple’s software update servers takes place if a user had upgraded their iOS using jailbreaking in the past or the iOS’s installed version has expired. iPhone Error 3194 can be resolved using the following methods:
The simplest method to fix this iOS system problem is by trying to update iTunes to their latest version. If this option does not work for you, try working with the second.
Checking Your Connections
The second method to fix iPhone Error 3194 is by checking your internet, firewall, and modem connections. If there is a problem in any of these connections or you have any settings in place which are blocking your device’s connection to the Apple servers, you need to change them.
Try disabling your Firewall, signing in using a WiFi, and ensuring all the modem connections are in place. If the problem persists, try the third method.
Changing Host Files
The third solution is quite complicated. It requires you to change host files on your computer, whether powered by Windows or MacOS. You can do this by following these steps:
- For Mac users: Launch the ‘Terminal Program’ on your device
- Type in the following address: sudo nano/private/etc/hosts
- Click on the ‘Return’ button
- If you see the host entry file gs.apple.com, add a ‘#’ and ‘[SPACE]’ at the beginning of it
- Save the file on your device and close the Terminal Program
- Restart your computer and try updating the iOS again
- For Windows users: search for system32/drivers/etc.
- Enter the host files
- Make the changes as suggested to Mac users above
- Restart your device and try to install iOS again
- If the gs.apple.com file does not appear after you type in the address, it means your device has no host file issues and you need other solutions
- If your device asks for the password you use to log into it before making changes to host files, enter it to proceed.
If this method also fails to solve this problem for you, then either you can get help from apple support or choose to use the Dr.Fone – Repair (iOS) software. It will help you fix iPhone error 3194 within seconds without you having to follow the cumbersome process.
