[Samsung Galaxy SL i9003] chongns:
i try to guide you the last time since no others (yet) able to help you.

u need to do from the beginning, what you need to do as below

1. flash pit file with odin, than unplug phone from com, take out the battery, put back the battery.

2. restart in download mode, start odin, connect the phone to com

flash xxkpe, (it should have 4 file) is phone boot?

3. if not, go in recovery, start adb key below commmond

su

mount

post the screen of the output

normally should look like below, the word you need to look for is mmcblk0, p1, p2 and p3

if all of the p1 to p3 is not present in the list, that mean you properly having broken mmc chip.
