Apple has stopped the system verification of IOS 14.4, which also means that devices that have upgraded the system are not allowed to be downgraded in the next version.

Stop signing means that users can no longer download outdated operating systems from Apple's servers. Traditionally, Apple will stop signing old codes regularly after releasing new versions of IOS to prevent users from installing previous versions of IOS. This practice can protect users from the impact of new threats and ensure that devices run the latest software.

Before Apple pushed IOS 14.4, it was a big blow to the third-party unofficial after-sales service of iPhone.
