After a week of launching iOS / iPadOS 14, on September 23, 2020, Apple officially locked the signing of iOS / iPadOS 13.7 version to prevent users from upgrading and downgrading to this version.
This is Apple's annual move every time a new version of iOS / iPadOS is released. This makes it mandatory for users to use a new version of iOS / iPadOS if you have upgraded to it.
If you follow TTJB regularly then you probably already know that currently iOS / iPadOS 14 is jailbreakable but limited to A9 (X) devices.
For A9 (X) -A11 (X) devices that are in iOS / iPadOS 13.7 and below, checkra1n completely supports these devices. You can jailbreak your device easily.
As for higher-end devices, you should stay in iOS 13 to wait for tools like unc0ver or odyssey to support.
