This ONT supports dual boot, as visible from the presence of kernel0 and kernel1, which contain the rootfs. The boot images can be swapped with the following command:

upgradetest switchver X

Where X can be 0/1, based on the image you want to boot from.

You can also clone the currently running image into the other slot using this command:

syn_version
