Being a noob as I am I tried to root my Samsung Galaxy Ace before noticing that there are different models with the same name. My phone is the GT-5839i which I later found that it still doesn't have any files to root, unroot or upgrade the firmware. Unfortunately I've only found that after rooting the phone and now I don't have any sound when using applications like youtube or the music player. Is there any way to solve the problem. Thanks.
