I need to return my vs980 to Verizon. I was going through the return to stock thread and it said I needed to boot into download mode. I think my recent ROM flash removed the download mode or something. Despite pressing/holding the proper hardware keys, download mode doesn't launch. I'm running cm11 (24A version). I saw something in the XDABBEB thread linking to a "restore download mode" file. Is this what I need? I guess the real question is how to get from cm11 24A to stock without download mode.
