Phone 11, iPhone 11 Pro, iPhone 11 Pro Max – how to power off, force restart, enter recovery mode, exit recovery mode, enter DFU mode, exit DFU mode, disable Face ID, and use Emergency SOS.
If the case is after clicking the Jailbreak button and respring, and it‘s stuck, to get out of that bootloop: Volume Up + Down + Power Button until you see the apple logo and release it.
And unc0ver doesn‘t and can‘t fill up your iPhone Storage, in that case, try the steps above, if it didn‘t help, plug it into your mac/pc and reset it. If it doesn‘t detect it, put it in recovery mode or DFU Mode
Recovery: Step 1: Connect your Apple device to a computer and open iTunes.
Step 2: Once connected, Up + Down + Power, in order to force restart. You must keep holding the power button until you see the iPhone Recovery Mode screen, don’t release the power button you see the Apple logo. It will probably take about 10 seconds for the iPhone Recovery Mode screen to appear.
DFU: Quick-press the Volume Up button Quick-press the Volume Down button Hold down the Side button until the screen goes black, then hold down both the Side button and Volume Down button. After 5 seconds, release the Side button while continuing to hold down the Volume Down button. If the Apple logo appears, the Side button was held down for too long. Nothing will be displayed on the screen when the device is in DFU mode. If open, iTunes will alert you that a device was detected in recovery mode/DFU Mode. Hope that helps.
