In this first version only Telnet is fully unlocked.
As explained in the readme file, use the UNLOCKEDTELNET.bin file if you need to flash the dump directly in the SPI NOR flash; use the rootfs.img file if you can upgrade the software version via web-gui (only Open Fiber distributed version).
In the future I'll improve this modded firmware unlocking SSH and maybe serial port (if it's locked by kernel, I can't unlock it).
