Update via telnet. How?

[goral]

Hi
I need to update vu+ uno 4k se to the latest version, currently OpenBh 5.5.1.012.
I do not have physical access to the receiver, how can I do this from telnet, I am interested in the command line, I use PuTTY.
I would like to do this without damaging the current settings, such as channel lists or oscam.
Thanks.

I wonder if you, instead of doing such an effort and using so much time in order to login to a forum, create a thread and post a message, tried a simple search over the internet. Maybe, something difficult like this:
"how update OpenBH telnet"...
Or, there is also AI... If you had, you'd surely got the answer
opkg update && opkg upgrade
and after this
reboot
