A10 Jailbreak has been achieved so we're going to share how to do. Do not forget it's now in BETA mode. It means you can see errors, brick devices.
You need to patch original Checkra1n in order to use this exploit in iOS 14.
This exploit is not working PASSCODE DEVICES. You have to wait for checkra.in 's offical release.
Now for mac owner there is a better release of Checkra1n which is patched and easy to use. You can download by here.
