4.2.1 OTA Update Fails

[Adam Breckels]

I was stuck with the same issue... I'm a total n00b but I finally figured it out.

Here's what I did.

Using only Nexus Root Toolkit 1.6 (Nexus Root Toolkit v1.6.1 | WugFresh)
1. Unlock - (didn't lose any data)
2. Root - (didn't lose any data)
3. Go through hell trying to figure out why it was erroring out...
4. Clicked "Flash Stock + Unroot" and pointed to the ROM I downloaded to PC from Google Dev page (https://developers.google.com/android/nexus/images)
5. Allowed it to wipe all data (manually backed up long before doing anything) - (lost all data... obviously)
6. Allowed it to restore the factory image as if I had it all along... Presto. 4.2.1 upgraded from 4.1.1.

After I figured it out, it made sense. You can likely use the backup/restore options too, but I prefer a fresh device, and just allowed my apps to download again from google. Since I use dropbox/gservers & my desktop to keep everything, there really wasn't any issue. I don't have call logs or texts, but that doesn't matter to me.

Hope this helps. Remember, I'm a n00b to Android (switched from iOS about 2.5 weeks ago and the GN I got was the first Android device I've ever laid finger prints on). Be nice please and thanks for all the near-hit tips!

Cheers!

Adam,
Thanks for the help but toolkits (imho) should never be used. The only if you read the thread you'll see I resolved the issue.

Toolkits save you time. I think doing something the easy way is fine so long as you know and understand the right way for when you get in a bind.

LOL, right! I was probably drunk when I said that.

I just use them because I'm lazy and don't wanna type a bunch of commands and go download the right images. I've been coding for a long time, doing "leet" things in command prompt for the sake of doing them lost it's appeal 10 years ago. I'll take a GUI that I don't have to maintain that's as good as anything I can write any day.

I'm having the same issue,

I haven't changed a thing on it, Just got a new nexus 7 32GB yesterday, was having 4.1.2 out of the box, got an update for 4.2,
the update downloads, device reboots, get the android icon showing that it is booting and after a few seconds , get another
android icon, this time flat with a red triangle for almost a minute. The device boots but there is no upgrade.

Now, I'm a total noob and as I said I haven't flashed/rooted or changed anything it was fresh out of the box.

Any suggestions on what needs to be done ?

Appreciate your help.
