The fastboot set active slot b command is used to switch the active boot slot on Android devices that support A/B partitioning system. This command allows users to change the current boot slot from slot A to slot B, which is particularly useful for testing different firmware versions or recovering from failed updates.
When using this command, ensure your device is in fastboot mode and connected to a computer with ADB and fastboot tools installed. The syntax is simple: fastboot set_active b. After execution, the device will boot from slot B on the next restart.
This feature is especially helpful for developers and advanced users who need to maintain multiple operating system versions or recover from boot failures. Always backup your data before switching boot slots to prevent potential data loss. |
