SamyGO

Can i install android packages if i root?

Of course no, you don't have Android TV

When rooted can i use more than one developer app? Does this add support for keyboard?

Rooted or not, you're not limited to "one developer app", but to "one server" (with several apps if you want). No change there.
No idea about keyboard, but I'd say it's already natively supported

In this case the server is the SamyGO one used for rooting, where i don't think there is SSIPTV for example. How many widgets there are on your server to use?
Support says on my model keyboard doesn't work.

Then use your own server...
Still no idea about keyboard, maybe support lies?

Once rooted, can i change server without losing things installed?
Tried with keyboard, all ports and on many apps but doesn't work.

No, you can use ONLY one server at once by design. Root changes nothing about that.

Try another keyboard?

I mean: once is rooted can i remove the server used for rooting from SamyGO and use a server of mine putting all i need there?
Tried all keyboards i have in my home, borrowed 2 or 3 from my friends. Nothing to do about it.

mmmh not sure (not D expert), better include SamyGO as well on your server imho.
