Rootfs not work pls help me

Just a wild guess. This could mean the installed kernel doesn't have the file system module that is compatible with the rootfs.

What should I do so, please open wrt throwing device but does not save a setting. When I restart resetting all settings.

The discussion might have continued from here.
