Question about Nokia 6300 Cellular Phone
Theme file like that is unsigned, which generally has a specific lifetime to be able installed on the phone. To fix this, change the phone date according to the date of theme still valid.
Open Menu > Settings > Find Date & Time. Set your Year to “2006′. Because some applications are certificated for 2005-2006. After setting your Year to 2006 install the application who gives certificate error. Finish your installation and you can set your current date back :)
Before it, make sure that you had check online certificate on the phone.
Go to "App. Mgr.", press "Options", press "Settings", make sure "Software installation" is set to "All", and "Online certif. check" is set to "Off".
