Ok, so my LED used to work when I was on 0.9, I updated to 1.0 when it came out and they still worked. I was experimenting with some different ROMs, but quickly returned to BB...however, when I did my LED no longer worked. Yes, I wiped wiped wiped each time I switched ROMs, and did a clean install of BB1.0 and still nothing... After reading through all of the fixes, applying V1fixes.zip, and having no luck, I read a thread where someone mentioned an app for switching the trackball LED. I figured why not give it a try. Here is what I did, and now I have a working LED! 1) Download "Nexus TrackBall Switcher" from the Market and install it. 2) Open the program and select "enable trackball now" in the bottom left corner. 3) Enjoy your working LED! I am afraid to mess with anything, but I have tested it and it works for e-mail and texts so far...I haven't received FB or Twitter updates, so I am not sure about those yet...but I'm not as concerned with those as e-mail and text. Let me know if this works for you guys as well... Good luck.
