N6600 problem!

After I formated the phone alot of stuff are still in the phone, some works like normal other doesn´t, and I can´t remove them aswell, so they take alot of space in yhe meny, what do you think I should do to remove the ikons frpm my phone??? __________________ I had problem with one game, but the phone is with my brother now so I don't know precisly, but I use FExplorer and find some stuff in System directory and can't remember did I delete something from Application directory also, that belongs to the game, so I delete them and they dissapered from menu.
