Apple Halts iOS 26.2 Beta 1 for iPhone Air and New iPad Pro Over Modem Concerns

Apple has stopped signing the iOS 26.2 and iPadOS 26.2 developer beta. The move happened just one day after the software’s initial release. This action prevents specific devices from installing the update.

The change affects the new iPhone Air, iPhone 16e, and cellular M5 iPad Pro models. According to reports, Apple has not provided a public reason for the sudden withdrawal. The software remains available for other compatible devices.

Custom C1 Chip Modem Identified as Common Factor

All affected devices share a key component. They use Apple’s new custom C1 or C1X cellular modem. This suggests a potential bug is tied to the new modem hardware and the beta software.

Users on these devices will still see the update prompt. However, the installation process will now fail. This swift action by Apple aims to prevent a problematic update from spreading. The company is likely working on a fixed version.

Developer Workflow Disrupted as Fix Timeline Remains Unclear

The unexpected halt disrupts testing for developers using the latest hardware. It underscores the inherent instability of early beta software. Apple’s priority appears to be preventing a poor user experience.

For now, developers must wait for a revised build. There is no official word on when a new beta will be released. The situation highlights the challenges of integrating new, custom silicon with software.

The sudden withdrawal of the iOS 26.2 beta underscores the critical nature of stable modem performance. Apple’s decisive action aims to avert potential connectivity issues for its newest devices, with a fixed update expected soon.
