Thi is what I read in XDA forum " . The PIT file is the partition information table. It tells your phone where different packages go on the phone, as well as how big partitions are on the phone. Without this information, Odin cannot properly re-partition your device "
So my question is as follows can or does anyone know how to write a PIT file that would do the following repartition the partitions on the phone like this 725Mb for the internal mem. 349Mb for ROM mem. 100Mb for data mem. And the rest 780Mb for the RAM .
