Fix unc0ver boot loop
If you are installing various tweaks it can happen that your device will restart and you will be forced to re-jailbreak your iPhone using unc0ver app. Sometimes the jailbreak process will be stuck on boot loop because of an issue related to one of the installed iOS tweaks.
The iPhone 7 infinite boot loop can be fixed.
Navigate to unc0ver → Settings and disable the Reload System Daemons option before re-jailbreak.
