Hi all,
I was able to solve my problem
.
I could not find the simulation U21 in service mode and then I read about a secret service mode.
This is the secret code that worked on the fs-3140
06141010
Got into the secret service mode and found sim U21. I ran it and tada! All works fine now and the password for web interface was reset back to admin00.
Just remember to run sim U917 and backup everything to a usb stick and also take not of your network settings.
Thanks
