UE40H6410 suddenly root gone

[marciucha]

hallo.
I have rootet my UE40H6410 successfully a month ago with H "Network" root. everything worked excellently.
suddenly is the root gone! nothing starts and works! no FTP, no Telnet.
Firmware is 2130 and still update disabled.
what is to do now?
is it possible everything about this once again? or brick?
can be root is gone because the Wifi connection wasn't available? i used 'libnetswitch'
sorry for my poor english.

Did you try delete the sam.log file in /mnt directory and did you read this?

I have solved the problem! thank you, wluczykijwf.
It was the deactivated Wifi connection on router. Because i dont need it everytime. I know, root still needs the Wifi. But it must be also connected with the router/internet on TV booting!?
I set on TV manualy from LAN>Wifi>connect with router>reboot TV>root works again!
