Ok on this post you will be able to get some information about the UI and the lockscreen.
At first here is the rar-file you will need:
Platinum UI + Lock
extract that und use the files as they should be used.
The Lockscreen is a modified version of the Sense3 Widgetlocker Lockscreen, so you will need to have Widgetlocker installed
. After that just put the zip file in data/com.tesla-something/themes and you can select it when you add a slider. The image files for the sliders should be on your device when you want to change them.
The rest should be very obvious. Install the UCCW files (you will need UCCW for that) and add them to you homescreen. I am using NOVA Launcher (Grid 7x6) and let my Widgets overlap each other, which is needed to correctly position the clock and the date.
The UI is for 2 homescreens. The circle on the left or the right already have the icons on them, just put the correct app in that spot and make it invisible with the transparent png file.
That should do the trick. If you have any more questions, feel free to ask and if you like this, plz hit my Thanks Button!
