Hi, my Nexus is on Android 5.0.1 (LRX22C). I haven't rooted or unlocked the bootloader; everything is totally stock. But I'm unable to successfully install the Android 5.1 OTA update. My phone downloads it, verifies it, then reboots to begin the installation process. After working on the update for a while, I see an error message (with an android on its back and a red "X"). The phone stays on that screen for a while, then eventually reboots without having installed the update. I've tried clearing cache, and it doesn't help. Anyone have any ideas?
