After launching developer betas for iPadOS 26.2 and iOS 26.2, the signing was shut down by Apple, preventing updates from installing on the iPhone 16e and iPhone Air as well as the new iPad Pro M5 cellular models. The reason is not known, but the gadgets use the C1X or C1 modem, and these chips are made by Apple.
Apple may have found a certain bug in iPadOS 26.2 and iOS 26.2 on their custom chip. Stopping signing may prevent users who have not updated from being affected by the issue. Updates will continue to appear for devices enrolled in the developer beta programs for iPadOS 26.2 and iOS 26.2.
It is unclear how long it will take the company to resolve the issue encountered. By then, developer betas would be reviewed and released for C1X and C1 modems. The signature was stopped to protect users from the problem of chips found by the company.
