- When you reboot to a different partition, your current settings (WiFi SSID/password, etc.) will not apply to a different partition. Different partitions might have completely different settings and even firmware.
|

- If you reboot to a partition which doesn't allow you to switch boot partitions (like stock vendor firmware), you might not be able to boot back to OpenWrt unless you reflash it, losing all the settings.
|
||||
- Some devices allow you to trigger reboot to an alternative partition by interrupting boot 3 times in a row (by resetting/switching off the device or pulling power). As these methods might be different for different devices, do your own homework.
|
||||
- Newer versions of this package try to mount alternative partition on compatible NAND routers in order to retrieve detailed firmware information. When that happens, it is normal to have messages similar to the below in the system log:
