Recover stick without UART access, possible?

[arpiecodes]

Hello!

I've attempted to adjust the scfg.txt by copying scfg_default.txt over from /config to the /userdata dir and adjusting the setting I needed to change (port slot ID ONT side for 10GE port from 000040 to 000000), however it seems that by doing so I've bricked the stick (it does not come 'up' anymore after reboot). It's an FS XGS-ONU-25-20NI.

Now I must say the module would not ping or come up without the fiber connected, so maybe the stick is actually booting and running but I cannot access it anymore by telnet.

Is there a way to get back in telnet to either reset the /userdata or regain access without opening the module?

Thanks in advance!
