I got a free optimus 2x from a buddy. phone's water damage stickers are red but he cant remember it ever getting soaked in water. He found the phone dead and then we noticed the stickers. the phone wont turn on and since I know LG or T-Mobile wont exchange it I figured id try to repair it myself. A friend told me that I should open it and clean the corrosion with some rubbing alcohol but I cant find any help online? Has anybody tried to do that to 2x or any phone for that matter? Any help would be appreciated
