Would seem to me that your Android TV should have a USB port that could read a stick or a USB hard drive. So you could download the git version and do all the stuff to the file you need to do (like extracting and renaming) on the PC/laptop. Then copy it to the USB stick and put it in your TVs USB port and copy it to where it needs to be. Surely Android TVs have some file manager you can use to do this.

Thanks for the suggestion, but that is not possible. My USB drive in that port is enabled has the main apps installation drive, and if I try to access it with any file explorer, the drive gets disabled. I would need a repo file or similar, but there is none. I really would like to know the reason for that lack of upgrading in official repo... it should be something logical... but I have no idea...

I know nothing about Android TVs. I do have Android tablets and they should be similar. Normal way of doing things like this would be to open a web browser, download the file from the git Mike has. Then follow the instructions HERE. It may appear to be quite involved but it's not.

As for updating the skin - Mike usually doesn't push an update until he feels the skin is ready for general release. Might be he's waiting for people to try it to see if there are any more bugs he can fix. What ever the reason may be it's Mike's decision to make. If you can't deal with it maybe a different skin might suit you needs better.

It's not possible with my configuration. I need a repository file or similar.

Each time I ask for the reasons of the lack of upgrade (+1 year) in official repo, I never get a proper reason, but the same kind of answer: "use another skin". That opacity and hostility is beyond me... I guess curiosity is not reason enough? Weird...
