My Sony KD-55X8000G TV is stuck on the Sony logo. I tried disconnecting LVDS and turning it on again, but the TV only showed a white LED (not blinking) and nothing else. Then, I reconnected LVDS, and it still only showed a white LED with the Sony logo. It seems it's not entering update mode. When I used a USB drive and named the firmware file upgrade_loader.pkg, the TV displayed "Updating..."(Sample image attached) but after about a quarter of the process, it restarted and got stuck on the Sony logo.
