Connect phone to computer
Have a look in folder MyColorScreen\Themer\tmp-dl
There may be a load of zipped themes with 24 digit alphanumeric names.
Copy these to computer.
Unzip each to their own folder.
Within these folders will be a folder called data.themer
Rename this to '24 character name of folder'.zip
Copy this zip file to Phone [MyColorScreen\Themer\Exported\zip\]
You should now b able to apply theme from 'Exported'
I would then customize theme to suit, and re-export with more sensible-sounding name, rather than 24 alphanumeric.
If anyone knows where there is an archive of zip files - let us know!
