I'm currently testing Series 40 v3.0 light format themes on my Nokia 2630 handset (S40 5th Edition LE) & encountering problems.
Below is the statement from Nokia Forum's website outlining the new features on Carbide 184.108.40.206.
Export in Series 40 Theme v3.0 light format converts images to Fractal Image Format (FIF) before they are stored in the theme deployment package (*.nth file); this offers much higher compression ratios than the standard Series 40 Theme v.3.0 compression, thereby reducing the size of the distribution file
When I package my v3.0 light format, it piles EXTRA file size on (in relation to just packaging it as v3.0)!
When I come to install & apply the v3.0 light theme on the 2630 device, it restores the device to a default theme!!!! When you install a v2.0 format instead, it installs & applies without any problems!! This makes no sense!!
Can anyone explain why the v3.0 light format files appear to be corrupt?
