samsung ue55es7080

[vimart]

Hello everyone I have a Samsung ue55es7080 and would like to install samygo
I tried with usb but the procedure while seeing samygo in the app, when I launch the installation I get the message out: there has been an interference in the network. try again later. (ERROR_OPENAPI_300).
someone has already installed on Eseries samygo, if so, help or guidance would be appreciated instead.
thanks

Has anyone an idea?
