Warning: The May 2026 update for Pixel 10, 10 Pro, 10 Pro XL and 10 Pro Fold devices contains a bootloader update that increments the anti-roll back version for the bootloader. This prevents the device from rolling back to previous vulnerable versions of the bootloader. After flashing the May 2026 update on these devices you won’t be able to flash and boot older Android 16 builds.

警告: Google Pixel 10、Google Pixel 10 Pro、Google Pixel 10 Pro XL、Google Pixel 10 Pro Fold デバイスの 2026 年 5 月のアップデートには、ブートローダーのロールバック防止バージョンを増分するブートローダー アップデートが含まれています。これにより、デバイスが以前の脆弱なバージョンのブートローダーにロールバックされるのを防ぐことができます。これらのデバイスで 2026 年 5 月のアップデートを書き込むと、古い Android 16 ビルドを書き込んで起動できなくなります。

The anti-rollback measure announced by Google for the “Pixel 10,” “Pixel 10 Pro,” “Pixel 10 Pro XL,” and “Pixel 10 Pro Fold” means that due to a bootloader update included in the May 2026 monthly software update, it is no longer possible to roll back to versions from April 2026 or earlier using the “Android Flash Tool” and factory/OTA images. This is a security measure implemented to prevent the installation of older software versions that may contain vulnerabilities.

While this is a security measure, it is a point of concern for some, as it means it will be impossible to revert to April 2026 or earlier versions even if a critical bug is discovered in the May 2026 monthly software update.
