The recent update to iOS, version 18.4.1, has raised concerns among some users who report that it may potentially render their iPhones unusable. Apple has urged users to immediately install the update to protect against a known security vulnerability. However, it may be wise to consider waiting for a patched version before proceeding.
One user shared their experience of a bricked iPhone following the update. The device became unable to detect its IMEI number, effectively locking the owner out as a security measure against theft. Attempts to restore the phone via a Mac or even at an Apple service center proved futile, and the only remedy available appears to be an expensive motherboard replacement.
Other users have expressed similar frustrations, with reports of Apple service centers failing to restore their devices as well. While there’s a debate surrounding whether a software update can cause such issues, Apple technicians have historically noted that software updates can indeed lead to device failures. The skepticism arises particularly in this case, as it seems unlikely that iOS update alone could disrupt the modem’s functionality.
However, there are parallels to past incidents, such as when the iPadOS 18 update malfunctioned on M4 iPad models, suggesting that pre-existing hardware defects might be exacerbated by software changes. Bricking incidents are not uncommon in the tech world. A notable example includes the One UI 6 update from last year, which rendered Galaxy S22 phones unusable for many users, particularly those with Exynos chipsets.
Given these instances, it may be prudent to temporarily disable automatic updates on your iPhone. Potential issues with the latest iOS update could take time to be addressed, similar to the delayed response regarding the iPadOS 18 situation.
