4.4 update caused bootlooping - Nexus 7 Q&A, Help & Troubleshooting

I took the 4.4 update and now the device bootloops. It was never rooted and never used much at all. I think no more than ten apps were ever installed on it. It belongs to my mother so I'm not familiar with it. I'm very familiar with android as I've been rooting and installing roms on my devices for over 2 years now but I was hoping I could get a quick solution from someone here so I don't spend my whole day trying to fix it
Thanks in advanced!

Now you can just flash stock firmware using fastboot.
Download the factory image from Google and flash it using fastboot.

4.1.2 >>> 4.2 unable to update

Okey so yesterday I couldn't wait anymore and wanted to update my Nexus 7 to 4.2 but couldn't.
After restarting it did initiate the update but right after it gave me a red triangle with a (!)
And now I can't see any updates anymore. I yet I'm on 4.1.2 still
Dang it..

Download the 4.2 factory images from google and flash via fastboot.
Consider yourself lucky and stay with 4.1.2
I have the same problem as well. When I first tried to get the update, the Android had a red ! And failed the update. Now, it says no update available....
I'm not sure if I should wait until a more stable version is out, however.

Aren't there enough 4.2 bashing threads that you feel the need to take this one off-topic?

Have you modified, frozen, or deleted any of the stock system files? The update checks for approximately 200 files and if any aren't stock, will fail. Your best bet, as someone else said, is going to be to fastboot flashing the stock image. Be forewarned that you'd be essentially starting from scratch as it would wipe your tablet, but I'd personally find that preferable since you'd be circumventing some of the issues that are irking the most vocal of 4.2's critics.

I actually just purchased the tablet, and out of the box the first thing I tried to do was update, and it failed.
I'm not very knowlegable about flashing the factory image myself, but I've heard about updating using a "toolkit"? Is this easier?

Yup, easier. But using a command line and the android SDK/fastboot isn't all that hard... maybe your issue is just the universes way of saying you should go learn a new trick. :cyclops:
However I doubt the universe will waste any energy punishing you if you choose to go the easy route. Plus, you can always read the thorough directions for both routes and make an educated decision before you get your hands even the least bit dirty.

Why not, it's a safe operation.
If you're completely stock, and update fails, either try again (and again, and again), or send it to repair (slowest). Or fastboot (fastest).

well, in that case, id rather root it and flash a custom rom, and thats probably what i am gonna end up doing... ill see, thanks for the answer

What a freakin mess....

So last night I decided (against my better judgment) to install TWRP recovery and flash the OTA. I did it, then had trouble rooting it. I decided to just say screw it and then restore my Nandroid backup (which I made like a good boy). Then I got a failed message on the restore. Booted back up to a fresh boot. Brand new "please select your language" .. Wtf? So then I went back to TWRP wiped everything tried to restore again. Now... Fail. So now I can't boot up because I wiped my ROM and I'm freaking stuck all over this 4.3 update. Really?
So now I will try to wait until WUGS toolkit gets updated and see if I can use it to flash a stock 4.3 image to the device then root it. I don't know if i can even use that toolkit if I don't have a ROM on the device. Anyone had experience with such a cluster and have advice? Any thoughts on why the nandroid didn't restore?

I could tell this was going downhill after reading this first sentence. Why would you install a custom recovery in order to flash an OTA? I don't mean to offend you but you have a lot of reading to do before you continue flashing anything.
I was in the same boat and confused as hell back in my Nexus One/Galaxy Nexus days. What I've discovered after a lot of trial and error as well as A LOT of reading, is that once you become extremely familiar with using ADB and Fastboot commands you realize how unbelievably simple this stuff really is. Even soft bricks are just small hiccups that won't stress you out anymore.
Learn how to properly use ADB/Fastboot commands through terminal (in OSX) or command prompt (n Windows) and you will realize that the toolkits are silly and do exactly the same thing.
Again, I mean this in the least offensive way possible. This is coming from someone who thought he bricked his Nexus 7 and let it sit in a drawer for 5 months before finally understanding ADB/Fastboot, pulling it out of the drawer and having it back up and running within 10 minutes...

This is completely OK. Follow THIS guide (just one of many) to learn how to setup your computer for ADB/Fastboot. Then follow THIS guide to learn how to flash back to completely stock. No current ROM is required on your phone to do any of this.
I swear this is a nightmare. I don't have TBU or anything. I literally have to start over. I am always VERY careful to read and make back ups that's why I use TWRP it's why I make Nandroids and this just sucks. Ugh. I have to piss and moan I don't know where to start lol. Thanks for letting me vent..

its not that there is trouble using root toolkits(even though there is occasionally), it the fact that you dont learn to do things the right way. and when little issues come up, the knowledge isnt there to fix things yourself. and those little minor things turn into major headaches/issues.

Well I do understand that point. It's a good one. I honestly don't know how to use ADB like I should. But at the same time it's a lot easier and if used properly can prevent mistakes. And good Devs make good money in donations so everyone is happy.. Lol :beer:

Nexus 4,4.3 update worst ever!!!(Need Help)

It's been 4 months since i bought Nexus 4 i was enjoying the 4.2 version no problems with heating issues(very minor no biggie),no performance problems neither graphic or application related issues..........however i did found out that there was Bluetooth problem in Nexus 4 devices,thought by next update it might solve that issue(bug).
Now i updated to 4.3 i received OTA and after installing it :-
The games i used to play lag ridiculously which didn't in previous 4.2,i saw drop in frame rates,the graphics were better before now the look like some 8-bit textures.....What the Hell?!?
My phone now get overheated my messaging and surfing which it didn't used to on 4.2 and it heats like anything when i am on call.....
Now it works very slow as if the update has degraded its hardware capability..... :crying:
Please provide me instructional guidance on how to rollback to my previous 4.2 version stock android(i did factory reset it didn't help,its still 4.3)
I need your HELP here!!!

is it that hard to use forum tools to search for keywords like... say... nexus 4 toolkit? come one people... it's a rule, it ain't matter you are a newbie you can always search... anyway go to nexus 4 section, then go to original android development and there you have toolkits in the first 5-6 threads. goog luck
I'd personally reflash the 4.3 factory image before going back, I've had no issues with 4.3 after a nice clean install (never used the OTA as I didn't wanna wait)

As been told, just flash the 4.2.2 image if you wanna go back but honestly i had no problems but applications incompatibility and that's not cause of 4.3 but the applications that doesn't support it yet.

4.2.2 was really much better to be honest,but from what i experienced was that my N4 became very slow i mean chrome taking time to open gmail taking time to open a mail and even refresh,the games i have like Vector,Virtual Tennis Challenge i saw like graphics screwed up........maybe i agree with you maybe be they are not compatible.....
But overheating,reduced performance,its to much to take,i googled a found people unable to turn on their N4 atleast am lucky my situation wasn't upto that.
Thats weird... I installed NFS Most Wanted, Asphalt 7 and they both worked nicely... I also thought there might be some graphics issues but its fine. Maybe you like to try again? maybe there's a missing wipe or something that is causing all these problems.

What's not easy? Download the factory image from Google and flash it the same way you would any factory image from Google. It has the easiest of all mobile phones to up/downgrade as it's a Nexus device

That was the same thing in my mind though,but it seems Nexus 4 has no option to rollback stock,the galaxy nexus series do,some i think.
Flashing 4.2.2 stock is the only solution i think:angel:
It isnt that hard. Just find yourself a good video tutorial if you like and all good

as far as i know, and that can be wrong, if your android is untouched (no root or anything else (like xposes framwork)) you will get the update over the air.
BUT if you don't there are factory images that you can download and flash your phone quite easily
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
or a toolkit to do it automatically
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312
i would recommend to do it with the first method. if something goes wrong you will know what is it and you can ask for help. with the toolkit if something goes wrong things are more complicated to find the error.
P.S. if you decide installing the factory images via console (first option), it is highly recommended to read the entire process first and after do the procedure.
My phone is rooted, but i dont have any custom ROMs or framework , will this affect it? Or when I get the update my root will simply be gone?

You'll lose root and the custom recovery with the ota. But if you haven't modified / deleted any system files you should get the ota.

Alright, thank you again for clearing things up!
It's also worth noting that Google pushes update at different times depending on which area you live in, so even if you read on the news that Lollypop is released on the Nexus 4, it may take a while for your phone to receive the OTA.
Personally, I advice you to install TWRP recovery, its safe and easy to install kernels and roms
