The info of BadBull was the solution !!! Thanks alot
I wanted to give up, but that was the decisive Tip
Perhaps we could include this tip in the first thread. My firmware version is 2110.1
Prefer again point out, as samygo once worked and did not work anymore after restart, I could prevent with putty when I entered via telnet command "reboot".
I do not know why but when I have made with the remote control the tv off and on, samygo root was history

Today I was able to bring to the root the first time to start, immediately after the root is not restarted with remote control but had the power outlet quickly switched off and on again. Root works!!!!
Maybe that has something to do with the error when you start Samygo !?
Thanks to everyone who helped me
