Every time my N4 downloads the update, I get a message that says "Verification Failed" and the update will begin downloading again. It has done this at least a dozen times now without successfully updating. I had no trouble with the 4.2.2 update but this is starting to get annoying. I have not modified my N4 in any way at all; it is not rooted, doesn't have a custom kernel and I have not unlocked the bootloader or anything like that. Earlier today I did a factory data reset in hopes that it would clear up the issue but I still get the "Verification Failed" message regardless of what I do. Does anybody have an idea of how to clear this issue up?
