I'm on stock 905. I was rooted but I unrooted myself using Supersu. I unfroze all programs that I had frozen in Titanium Back Up. I uninstalled Set CPU just as a precaution. I wiped cache partition. I was able to download the OTA to 100%. My phone rebooted and I got a picture of the green android dude next to an open box with a yellow status bar underneath it. The yellow status bar got about 25% of the way and then the open box changed to a triangle with an exclamation point within it. About 10 seconds later my phone reboots and gets to my home screen and then I get a message that pops up that says, "The software update failed!". I've tried it three times all with the same exact results. Has anyone else been having this issue or know how to fix it?
