Im also doing according to this video. One time I already crashed my acc so now before changing character ID Im checking it. I take any character i have, searching his exp value as I32 in IGG, changing his exp in game than searching again until I have 2 value in IGG, go to main menu in MK, choose one value, go to memory and goto, find values with EXP, character lvl, fusion lvl, unknown value(0) and character ID. So this found ID is different from the list given by you. For example hellspawn scorpion i have 56621 but in your list it is 53653. What am i doing wrong?
btw changing char level and fusion lvl working perfect.
