I read tutorial from a lot of source, but can't enter DFU mode. After many time stuck at step 3, iPhone back to recovery mode. I tried to release and hold again power button with vol down.... and.... iPhone 8 entered to DFU mode.
How to get into DFU mode on iPhone 8 (from 9to5mac https://9to5mac.com/2017/10/11/iphone...)
Step 1: Connect your iPhone to your Mac or PC with a Lightning to USB cable.
Step 2: Press and release the Volume Up button, press and release the Volume Down button, and press and hold the Side button for 10 seconds until the screen turns black.
Step 3: While still holding the Side button, press and hold the Volume Down button for 5 seconds, and then release the Side button while continuing to hold the Volume Down button for another 10 seconds. The screen should remain black.
Step 4: Launch iTunes, and you should see a message stating that “iTunes has detected an iPhone in recovery mode. You must restore this iPhone before it can be used with iTunes.”
