I want to go back to stock, but Captivate wont enter Download Mode. I have tried every combination of button holds online. Is it possible I did something to disable it by rooting and such? I cant flash the stock ROM back on until I get into the download mode again. Is it soft bricked, or what? It comes on now with black screen, and keeps giving errors like launcher has stopped working. Phone wont even connect to PC now thru USB. please help thanks.
