Fiberhome Sr120a Firmware 2021

The root filesystem utilizes the SquashFS format, often compressed with LZMA or a proprietary variant to reduce footprint. The file hierarchy adheres to the Filesystem Hierarchy Standard (FHS) but includes proprietary directories such as /fh and /tmp/var/config where the device stores runtime configuration and GPON authentication keys.

Perform a clean factory reset. This clears conflicting configuration cache left over from the older firmware version. Missing ISP Settings
