I just received the message to update today. I've tried 10 times to get it to install but it fails. It downloaded just fine then the status bar under the green droid guy gets about 1/5 of the way and a dead android with his chest open and a red triangle above him pop up. It says Error Code 402 update failed. I'm not rooted, tried it via 4G and wifi, completed a hard reset skipping all the account and info setup only activating and it still would not install?!? Can anyone tell me what to do to fix this issue? I would really appreciate it!
