There are many solutions.

I have had this error numerous times and I believe I have most of the solutions.

The first thing to do would be to free up as much space a possible. So, dummying jap, korean and the one with the funny name. The next thing you got to do is look around your flash and see if there is anything there that shouldn't. For example backed up rcos files which theme creators so kindly include,.. continue later,..DINNER!! ;)
