Steam would Destroy it i would think. it will get into places you cant reach to clean and dry it. The only thing i would think of (last resort of course befor throwing it) would be Heat gun it to around 180 to start and somehow try to flatten it. sorry i couldnt have been more help. Does the Sim No work when its pluged in? also have you tried just levering the metal plate out a bit where the sim inserts? regards chris
Yep thats the only way mate it sounds Like the Main Chip Has some Dodgy Solder Connections Reheating Both the Large Chips Is usually the Best option As in my experience with playstation 3s you can do one and it will turn out to be the other one. If you need a Guide Have a LOok at BGA Reflow PS3 on Youtube there are many a video that started me off fixing them :) and forgod sakes... Dont do the oven trick! i have Bricked Many a Board with that! invest in a cheaper heat gun if need be they do the trick... iv been using the same one for years!! Good Luck!
