Hi guys, I am attempting to unroot my phone and I am getting stuck at the "download mode" part. I enter download mode by holding + key while I plug in USB, fine. But then my phone goes to the "firmware update" screen and just sits there at 0%, saying "rooted" in red at the bottom. My PC shows a dialog box that says "installing drivers", but after a few minutes it says "failed". I've done a factory reset hoping that would help, but it didn't.
No clue what to do... any help?
ps. I attached a screenshot of my pc.
