BBOB is resetting 10-15 seconds after power on.

The reset is performed by installation script. Try to remove it from system (System -> Startup -> Local Startup, clear field and press Save) and install libraries manually.

List of required libraries: dosfstools kmod-fs-exfat libblkid1 kmod-sdhci-mt7620 libstdcpp6 mc psmisc

Use terminal (PuTTY or similar): opkg update opkg install lib_name

After last installation restore startup script. (bbobuffer_settings.tar.gzip -> rc.local file).
