this is a script to dualboot your iphone on ios 15 with 14
A script that lets you dualboot iOS 15-14. and 13.6/13.7, (semi-tethered) using checkm8-vulnerable devices. This is not a downgrade, however you can use downr1n instead.
This will not work on devices with iOS 16.
do you want to dualboot or downgrade to lower than ios 12?
1: Semaphorin this is free and works great 2: limefix (paid) i didn't test it but it should work nice (this uses a blackbird exploit which makes it more stable than dualra1n)
For devices with A11 SoCs, iOS 14.2 and earlier will fail to boot. Therefore, use iOS 14.3 or later instead.
Dualbooting iOS 13 only supports 13.6 and 13.7 and will most likely NOT support any lower!
iPhones with a capacitive home button (ex. iPhone 7/7+) on iOS 13 WILL NOT HAVE A WORKING HOME BUTTON. To get around this you can enable assistive touch in the main iOS and it will pass onto the dualbooted OS
Devices that only have 16GB of storage, can use the --downgrade option instead of --dualboot, this is going to remove the main iOS and replace it with whatever you chose to downgrade to. To go back to the original iOS that you started with, just restore your device (you can use iTunes).
