Not so clear to me sorry, I specifically do not want to flash a ROM with the changed memory, or:
1. am i misunderstanding, or
2. am I mistaken in believing this can be done without flashing a new ROM, which is what I thought Splinter's process was about
sorry if this is not clear enough for you mrrog. flashing ROMs may not be for you then.
you see, the UG802 has several types of storage memory and two of which are inside the device. the two storage space inside the device is the internal memory and the internal sdcard. that's why when you see your storage space under settings you see three types of memories which are the internal storage, NAND storage(which is the internal sdcard), and the sd card(which is the external sdcard). this shouldn't be a problem but the apps sees the NAND storage as your external sdcard so you don't benefit from installing apps to your micro sdcard. maybe there are apps or other mods to be able to make the apps see the external sdcard as the real external sdcard but i havent been successful with that.
you may skip all the steps and do the editing of the vold.fstab file provided you are rooted. but doing this alone will lose you the internal sdcard memory and will have a miniscule amount of internal memory.
the reason why you will need to flash a ROM with a modified parameter file is to allocate the internal sdcard memory to the internal memory partition which would make it simpler for you since you will only have the internal memory and the external sdcard after you do everything
