I have this same problem. I bought the tablet used wiped the OS and the cache partition. WiFi and Bluetooth still grayed out and auto switches to the off position after a few seconds. I would think using safe mode, and a wipe that this is not a software issue. I have been reading and there are a lot of other users who have this problem. I have seen some people mention that they reflowed or soldered. This is risky for obvious reasons. If any one has a diagram or a chip set map I can pull the mobo and see if there is a bad solder joint. I have seen repairs done before with epoxies and would be willing to try to repair so we can put up a guide. I think it's pretty lousy of samsung to put out a product and have so many come up defective after weeks or a few months of use.
