I presume you are refering to slyk 1080 r19 and not my slyk Q
*UPDATED* Slyk 1080 R19 (Install - FAQs)
All files are on the first post of that thread.
It might seem confusing, but that is because that skin is quite customisable depending on how you want certain things to display.
Just installing the main IPK will give you the skin and the sky look. Everything else is optional.
Download and install the main skin file.
Reboot GUI.
The other files are image dependent. So if you have openvix installed, use the openvix files.
If you have openatv installed use the openatv files.
Install the movie planner mod IPK - this changes the movie planner screen to look a bit more similar to sky rather than the very basic enigma2 movie planner screen.
Install epg buttons / tabs mod IPK (v3.0 if using a new image). This changes the coloured button text and also allows the tab of bouquets to appear at the top of the EPG.
Install toppicks mod.
Now each of these installs have there own post and instructions in that thread on how to set up and use correctly.
Have a play, f you get stuck just ask. I or someone else will assist you with getting it all working.
