Apple has closed the iOS 16 verification channel. There is no going back after upgrading to iOS 17!

Apple released iOS 17.0.3 today and closed the downgrade channel for previous versions. This means that users will not be able to roll back to the old version after upgrading to the new version, so you need to consider carefully before upgrading.

iOS 17.0.3 is an emergency update released to solve the iPhone overheating problem. Normally, for security reasons, Apple gradually closes the downgrade channel for older versions of iOS to prevent users from rolling back to older system versions.

The update not only fixes important bugs, but also enhances security and, most importantly, resolves an issue that could cause the iPhone to overheat. Apple stated that the overheating issue stems from software rather than hardware or design flaws, so it will not solve the overheating issue by reducing the performance of the A17 Pro chip.

It should be noted that the downgrade channel for iOS 17.0.2 has not been closed yet, which means there is still an additional option for users who want to upgrade to the latest system.

In summary, if you are experiencing iPhone overheating issues, upgrading to iOS 17.0.3 may be an effective way to solve the problem. However, please make sure to back up important data before upgrading and carefully consider whether to upgrade to avoid possible inconveniences.
