Quoted from awesomeaja:I noticed there was corrosion on the battery pack/board area, so I desoldered it, and replaced it with a battery pack I made, but in doing this I made huge mistake by running the AAs in series instead of in parallel
You didnt do anything wrong here, the batteries should be installed in series to provide 5V to the memory. Recheck all of your ribbon cables, you may have one off a row.
The board corrosion is another issue; if not properly treated, it will eventually destroy the board.
