I need to do somethings.
I have a 3310 4.45 fls 2097152bytes With font chunk 17048 bytes and text chunk
130044 byte.
Another 3310 5.55 fls with font chunk1900455 bytes font chunk about 9000 and text chunk about 120000bytes .
I want to copy font and texts of 4.45 to 5.55 But when i do that length of target file remains on changed.
I changed ppm length in flash.explode file but then when i want to flash i get message flash files must be n*64k
I changed length to nearst n*64k but hen i flash all menu cintect are bad.
how to import diffrent size font in an other flash?
