    Will restoring ios version with dfu mode void my warranty? I never had jailbreak on my phone.

    No, why should it?
    There are even technical reasons that require putting the iPhone/iPad into DFU mode.

    I don't know to be honest, I read on internet and some people said that it can void my warranty so I was suspect about it.
    Can an Apple employee know if the phone was restored with dfu mode or not?

    Apple will sometimes recommend a DFU mode restore as part of the troubleshooting process. It doesn't matter if they could tell.

    Where do you even read it from? Strangely, you even mention jailbreak since it’s linked to DFU. DFU mode is used to update or downgrade firmware or restore from jailbreak. Jailbreaking voids warranty because it’s modify iOS via exploits to runs unauthorized tweaks and themes from Cydia (alternative to App Store)

    Even if you were to jailbreak, a simple restore and Apple would never know.

    I read on the internet about DFU and Jailbreak but never tried and I will never try because I don't want to loose my warranty

    It is recommended to DFU mode to restore from jailbreak but Apple will not even know if you jailbreak before a restore. The restore will basically wipe it. I used to jailbreak back in the day when it was full untethered and I would DFU mode at the Apple Store before servicing it. :D

    DFU mode (Device Firmware Upgrade) is an official feature built in by Apple. It definitely does NOT void the warranty.

    So in conclusion it is ok to do it?
    I want to mention that I have a SIM-locked iPhone so this won't affect anything right?

    Jailbreak doesn’t void your warranty. DFU doesn’t void your warranty. Jailbreak will however cause you to not receive any sort of technical support from Apple until the device is put onto the latest public release of iOS.

    Yes perfectly fine to do.

    It does break EULA. If any part of the device fails, Apple will blame it on the current jailbreak and will not repair it, until returned to original ( or current ) iOS.
