Apple’s latest software iOS 18.4.1 Update aimed at addressing critical security vulnerabilities, has unexpectedly led to serious issues for some iPhone users. Released just over a week ago, the update was widely recommended due to its fixes for two zero-day security flaws and other important bug resolutions. However, numerous reports have surfaced, particularly on the r/iphone subreddit, of iPhones becoming non-functional after the update. Users have described situations where their devices refuse to power on or connect to cellular networks after installing the new software. One Reddit user shared, ‘The iOS 18.4.1 update bricked my cell service and hardware on the iPhone 15 Pro. I cannot connect to cell service. Diagnostic says hardware issue,” highlighting the severity of the situation.
Section 2: Root Causes Remain Unclear as Frustrations Grow
The exact cause behind the bricking incidents remains uncertain. Some users speculate that the iOS 18.4.1 Update might be causing iPhones to lose their IMEI numbers, a crucial identifier for device verification. Without this number, the phone fails to boot properly, rendering it unusable. Several affected individuals have reported that even Apple service centers have struggled to restore their devices. Although Apple has not yet officially addressed the issue, widespread user frustration suggests that the problem may be more common than initially expected. Reports indicate that newer models, such as the iPhone 15 Pro and iPhone 16, are the most affected. This incident follows a similar situation in September 2024, when an iPadOS 18 update reportedly bricked some M4 iPad Pro devices, raising additional concerns about the stability of Apple’s recent software releases.
Experts Advise Caution as Apple Remains Silent
Given the uncertainty and the potential risk of rendering devices inoperable, security experts are urging iPhone owners to delay updating to iOS 18.4.1 if they have not already done so. Anthony Spadafora, Managing Editor of Security, explained that while the update addresses significant security vulnerabilities, these zero-day flaws typically target high-profile individuals such as executives and politicians. Therefore, the average user faces a relatively low immediate risk from the flaws. Spadafora advises that it is safer to wait for a fully stable iOS 18.4.1 Update that resolves both the security issues and the current bricking problems. Until Apple provides an official response or solution, users are encouraged to remain cautious and avoid updating unless absolutely necessary.
