mobile

since lollipop dropped today, I want to update. When I go into the download process all goes well, but when it starts flashing it, the progress bar lights up, starts going, then goes away and I'd get the red triangle. At which point I restast and it says it failed, try again later. I'm wondering if my recovery isn't up to date, but I can't find one for 3.42.502.1. If someone can upload or link me one I'd be grateful. Thanks in advance,
