3.Step: Open CoolBooter on your iPhone. Then press the Install button. The app will ask you which version of iOS do you want to Dual Boot. Select Ios 6.0. It is the first option. Then press the Storage button in the right bottom corner. Select 7GB (Or however much you want) then press Select. And now you can press I’m ready. The app will ask you about a Custom Bootlogo that we don’t need, so press No, and it will ask you about Verbose Boot, we will click Yes for this one.The process will begin slowly with downloading the version of Ios. After waiting a little the app will ask you to reboot which you will by pressing the reboot button. It will boot back up into Ios 9.3.6. The app might crash while opening it and it is because the jailbreak became invalid while rebooting. So go back into carbon.sep.lol and repeat the process of jailbreaking,this time though you WILL NOT HAVE TO INSTALL THE PROFILE AGAIN, just press the Run button until it works. Then after the device reboots go into CoolBooter and press Boot. The app will say to Lock your device. You can do that by just pressing the power button on the iPhone. From now you are going to wait until the device reboots. Then you are gonna let the phone do it’s thing.
