I read a lot about how I am not the only person stuck in "safe mode" because my volume down button would not cooperate. After a lengthy process I concluded that the alcohol solution logically was my most logic solution. wait I have no isopropyl alcohol so I used ronsonal lighter fluid....came in a squirt bottle and stood out in bright yellow. I merely removed back cover and with problem area (mostly) downwards for drainage cleansed safe mode away. Took 5 minutes(depends on amount of fluid used) and voilà like new I even did my charge port and headphone jack. Warranty was null and void and I did not tell you to do it, but it worked GREAT and was easy with little drying time. Thought I should share.
