[Nexus 4 General] mobilehavoc:
Quick instructions if you are stock, unrooted without CWM. You MUST have unlocked your bootloader and have ADB (Android SDK installed) already for this to work.

1. Download this to your computer -> http://android.clients.google.com/p....signed-occam-JOP40D-from-JOP40C.625f5f7c.zip

2. Turn off your phone

3. Hold down Volume - and Power to get into Fastboot

4. Scroll down to Recovery and enter.

5. On the No Command Android screen hold Power and Volume + to get to menu. Might take a few attempts to get timing right

6. On the menu select Update from ADB

7. Connect your phone to computer with USB

8. On computer type "adb sideload 625f5f7c6524.signed-occam-JOP40D-from-JOP40C.625f5f7c.zip"

9. You should then see this output: "sending: 'sideload' 100%"

10. Your phone screen will say System Update or something and it will install the OTA.

Once done just select reboot in recovery and you're done. You can use this method for ALL future OTAs - all you need is the update zip. This works on all Nexus including Nexus 7, assuming Nexus 10 and GNexus.

No longer need to wait for OTAs. Enjoy!
[Nexus 4 General] Rusty!:
You don't need an unlocked bootloader for that.

I want to know what you do if you're rooted, unlocked, CWM and need the bathroom? :D
[Nexus 4 General] droidmakespwn:
The first thing I did when I powered my phone on was root, unlock, and install twrp. When the first ota showed up I just downloaded like normal and hit the install button. It proceeded to successfully flash in twrp.
[Nexus 4 General] 3dawg:
Definitely something to consider :good:
[Nexus 4 General] Rusty!:
That's fine, although it'll break root unless you have some sort of root-keeper thing.
[Nexus 4 General] jaju123:
I have a German one. No update.
[Nexus 4 General] javacody:
I gotta say I love having a nexus device.

I've had the G1, the Vibrant, the I9300 Galaxy S, and now this. And updating is so easy. I had franco's kernel flashed and I had unistalled Gmail. So the OTA patch wouldnt' work.

Just downloaded the factory image zip, fastboot flashed system.img and boot.img, started Recovery and flashed the update. Wiped cache and dalvik cache to be safe and restarted. Good to go!

Nothing but a Nexus from now on...
[Nexus 4 General] Chochiwpg:
I am rooted, have an unlocked bootloader but running stock recovery. This should mean that I will get the OTA update via about phone, system updates correct?

Showing that I am up to date right now running version 4.2. I am in Canada, not sure if location has anything to do with the update.
[Nexus 4 General] Imppy:
Anyone get this update in Canada?
[Nexus 4 General] Chochiwpg:
Just read on MobileSyrup that it will take a couple days for all the updates to roll out to people. Maybe they are doing it by region?

Thanks for the link. Installed nice with ClockworkMod. Root and CWM still active after reboot.
[Nexus 4 General] originlabs:
Can't apply this till I finish work, but can anyone comment on the screen gamma levels with 4.2.1?
[Nexus 4 General] madj42:
Flashed this and I lost root. Used superboot to fix that.
[Nexus 4 General] Josh98:
Noticable improvements anywhere? Battery?
[Nexus 4 General] stangy:
There's got to be a change log somewhere?
[Nexus 4 General] :
I have opened the archive and I can tell that (if it is what I think : diff files) there is a lot of changes. Not big changes, but changes.
[Nexus 4 General] Rusty!:
Almost everything is 'changed', they get version bumps from 4.2 to 4.2.1
[Nexus 4 General] bkai:
Got it this morning around 1:00am (CST) and posted on everythingandroid. I completely forgot about the December thing so it had me really confused for a bit :)
[Nexus 4 General] bagou01:
ok but can anyone tell which of the issues reported has been corrected?

december missing : we know it's fixed

flickering screen ?

random reboot ?

lack of fluidity compared to 4.1.2 ?

battery drain fast?

slow battery charging ?
[Nexus 4 General] evaradar:
Okay guys so after glancing through the threads quickly, it seems I can't get the OTA nor flash it due to me having the TWRP recovery. My phone is otherwise bone stock with root privileges.

Now if I want to reflash the stock recovery, will I lose all my user apps, data, files, etc? Will I also lose the same if I flash TWRP again?

What are the steps? Thanks. PS I have Voodoo Rootkeeper installed to preserve root/SuperSU access.
[Nexus 4 General] tehrules:
No update for my nexus, I'm in the UK. I have purchased from mine from O2 UK

100% stock.
[Nexus 4 General] bkai:
I've never experienced any of those issues at all (except for December of course). Are you using a custom launcher?
[Nexus 4 General] Jordanooo:
Flash .zip from post #3

Worked for me on TWRP. Lost root though
[Nexus 4 General] Imppy:
You installed using the .zip in post 3 and everything working great?
[Nexus 4 General] bagou01:
no, pure stock, no root no nothing, and all these issues have been reported and confirmed (random reboots seems to be linked to HD widgets)
[Nexus 4 General] evaradar:
Thanks for the heads up! PS I installed Voodoo Rootkeeper and activated it. That should preserve root right?

So just move that file to internal storage, boot into TWRP and install from zip? No need to use the fastboot install/flash command ?
[Nexus 4 General] bmallory:
on a stock (but rooted) install, sideloading the zip from post #3 worked fine. I had to re-root the phone though.
[Nexus 4 General] Jordanooo:
Yeah, I downloaded straight to my phone and flashed through TWRP. Forgot to try root preserve.

It may do, though I can't confirm it. If it doesn't work, it took me like 1 minute to re-root

I flashed that .zip through TWRP and it worked here, just lost root. No other problems
[Nexus 4 General] evaradar:
Gotcha! Thanks again. Will try it out now.
[Nexus 4 General] a5ehren:
Random reboots and battery drain are usually linked to misbehaving apps. Pressure the dev to fix their stuff.
[Nexus 4 General] bagou01:
they are confirmed to be linked to a bug in lockscreen widgets, dev as well as google seem to be aware of that and working on it
[Nexus 4 General] evaradar:
Just updated to 4.2.1 using the file from post #3. Used Voodoo's OTA Rootkeeper to preserve root and everything worked fine. Used TWRP to install that zip file.
[Nexus 4 General] ericshmerick:
1.1 mb? No way. An update that small can only be a few lines of code - i.e. adding back in December.

Nothing special here. Just adding back in December I'd bet. I'm all about getting excited for an OTA, but to go through the trouble to flash this is crazy. Unless you were born in December!
[Nexus 4 General] mbwelch:
Sometimes, but in theory an app should never be able to bring down the entire OS. As a previous Nexus owner, my experience has been that the random reboots (OS crashes) are fairly typical on the new Nexus devices. Usually by spring or summer, Google has them all worked out.
[Nexus 4 General] gtg465x:
Actually tens of thousands of lines of code can be contained within 1 MB. My Windows Phone app, MetrofaceLIFT, has over 1000 lines of code and is only about 200 KB. The files contained within the update are diff files, meaning they contain only the bits of each file that changed. Unzip the update yourself and you'll see that hundreds of files are changed in this update. Some changes are just version bumps, sure, but others likely contain more code than you think. From analyzing the update, I guarantee there are bluetooth and nfc fixes, camera tweaks, and sensor tweaks. You may not notice them in day to day use, but they're there. Hell, one guy in this thread already said this update fixed compatibility with his NFC tags.
[Nexus 4 General] skttls:
I can confirm that this method works. I preserved root, updated, and restored root using Voodoo's OTA Rootkeeper.

Thanks for the tip!
[Nexus 4 General] hunterhp:
Watch out, they might have sneaked in an LTE patch
[Nexus 4 General] bozzykid:
4.2 is known to cause reboots. Apps should never be able to reboot a phone.
[Nexus 4 General] italia0101:
its been confirmed that it still works :)
[Nexus 4 General] bozzykid:
Generally Google just randomly rolls it out. Rarely is it done by region unless there are radio changes and Google finds issues with certain carriers (no radio changes in this build).
[Nexus 4 General] 3dawg:
After flashing through CWM, it notified me that root had been broken and asked if I wanted to repair it. I said no because I already backed up root in RootKeeper. Would it have worked if I pressed yes?
[Nexus 4 General] bozzykid:
Sorry but there are definitely NFC and sensor changes in this release. Since they are patch files, it takes very little space when the changes are only bug fixes.
[Nexus 4 General] tkm89:
It did for me.
[Nexus 4 General] 3dawg:
To clarify, after flashing the new OTA update through CWM, CWM notified you that root had broken and asked whether you wanted to restore it. You said yes, and it worked?

Sorry for the bluntness, I want to make sure we're on the same page here.

Do I have to move it to the root of my storage? I downloaded the ota from post three but tried to flash it from my download folder in TWRP. Also I have ota root keeper installed
[Nexus 4 General] eep2378:
THIS^^^^:D
[Nexus 4 General] CMNein:
Did you install the AOSP browser and rename the Chrome provider, etc...?

If so, rename the files back, or reinstall if you deleted them.
[Nexus 4 General] Hero_Guy:
Nope. Completely stock rooted minus having TWRP installed. I did delete some Google apps like currents, that might be why
[Nexus 4 General] yozpalang:
How did you guys flashed the zip from post #3 I'm on everything stock but when I boot into stock recovery all I get is "no command" in the middle of the screen.:confused::confused::confused::confused:
[Nexus 4 General] CMNein:
I didn't try flashing it, but the first time I tried to sideload it assert failed because I forgot to name the Chrome files back.

Anyways, that's not your issue, unless you uninstalled any system apps? Perhaps try sideloading from TWRP > Advanced, if you have adb installed on your PC.
[Nexus 4 General] Hero_Guy:
Yeah I deleted some Google apps like currents that I'm currently reinstalling. Unfortunately I'm away from a computer
[Nexus 4 General] FatalityBoyZahy:
So I should be able to ADB side load even if I uninstalled some system apps?
[Nexus 4 General] Rusty!:
Don't delete things you don't want, disable them.
[Nexus 4 General] CMNein:
No, you'll fail assert with an F- ;)

Well darn, how can I get the APK's for the email app and the play apps

They always have before with Nexus devices. I've seen plenty of these to know there is no order and no location preference normally.
[Nexus 4 General] ibegary:
Full Stock except with Matrix Kernel and Rooted/CWM Installed.

Installed from Post #3 using CWM.

When I went to reboot system, CWM asked if it should fix the stock recovery re-flashing - I said yes.

Then it asked if it should fix root - I said yes.

Rebooted and works just fine so far. Just a FYI.
[Nexus 4 General] linelock:
I had to get them from the stock rom posted in the Dev section.
[Nexus 4 General] tweaked:
You can get them from a stock rom (pull the information out yourself.)

Or you can just install the Stock rooted rom again.

Next time, using Titanium, back the app up before you delete it and that way you can restore it. (Limited space could hamper you here.)
[Nexus 4 General] raazman:
If I changed my dpi, do I have to set it back to the default in order to update or is it fine to do so without it?
[Nexus 4 General] Rusty!:
The quickest thing to do would be to simply fastboot flash system.
[Nexus 4 General] Chochiwpg:
If you don't use RootKeeper, can't you just boot into CWM or TWRP. Flash the .zip and then flash SuperSU and binaries .zip as well and then reboot the phone? Wouldn't that in effect flash the new version of the OS and then root the device?
[Nexus 4 General] 918273645ams:
still no update >_<
[Nexus 4 General] linelock:
Yes, but there is no need, at least with CWM as it gives you the option to preserve root.
[Nexus 4 General] aznxk3vi17:
Just flash the file in post #3.
[Nexus 4 General] Chochiwpg:
Sweet thanks. I kind of want to keep the stock recovery for now, so I might just boot into CWM to flash the update instead of flashing CWM. Thanks for your help.
[Nexus 4 General] stuart0001:
Can anyone please check the following is fixed:

1. 4.2 update made the display colours paler/washed out. Does 4.2.1 change this at all?

2. 4.2 broke car mode meaning your car dock app didn't take over the default launcher whilst in car mode

Many thanks
[Nexus 4 General] tkm89:
Correct. It gave me an option of keeping CWM Recovery and whether to keep root or not.
[Nexus 4 General] shojus:
So I have the update notification on my status bar and I downloaded rootkeeper so if I let it update on it's own will it work that way? Or should I just flash it through twrp? Thanks in advance! :)
[Nexus 4 General] soder:
I'm pretty new on being on stock ROM and I got some questions about this OTA or update.zip file.

I've rooted the rom, and also moved some apps to /system/app and also flashed TWRP recovery.

Can I install this update, or do I need to do something else? Like, flash back stock recovery? Does it work to have done some mods to /system if I only move back to stock recovery?

/Söder
[Nexus 4 General] bozzykid:
Are you talking about the Nexus 4? It shipped with 4.2 and had a small update afterwards. But I don't think the original update 4.2 changed anything with the colors.
[Nexus 4 General] italia0101:
Not sure if a placebo effect .. Or that I've gotten used to it m but my touch response seems better after 4.2.1
[Nexus 4 General] CMNein:
It doesn't matter what you've moved to system, as long as you haven't removed/renamed any stock system files you're okay.

I had all pre-existing files intact in system so I passed assert. I sideloaded the zip however, so I had to reflash TWRP and SuperSU. I've seen other people report that CWM prompted them about whether they wanted to retain CWM vs the stock recovery +/- root (?).
[Nexus 4 General] stuart0001:
Yes, the nexus 4 earlier ota degraded the display colour. See link below.
[Nexus 4 General] soder:
What do you mean with "sideloaded"?

Does it matter if I receive the OTA or if I download the .zip manually? And does it work with TWRP or do I need the stock recovery?

/Söder
[Nexus 4 General] CMNein:
adb sideload

You can flash the zip with TWRP, but it will fail if you've renamed/deleted any stock system apps.
[Nexus 4 General] yokken:
Really wanted to update while at work, but I uninstalled Play Magazines, Currents, all that BS that comes on the phone. I'll wait until it's merged into another build, or flash the stock image when I get home. I wonder if it will fix my Wi-Fi woes...

Post 420 yeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
[Nexus 4 General] soder:
Well I haven't removed anything myself. I've installed SuperSU, that other stuff that comes with root, some security app, and ALSA,

EDIT: Do I just flash it in TWRP like any other .zip?

/Söder
[Nexus 4 General] CMNein:
You should be okay then. Just be ready to reflash your recovery via fastboot and SuperSU if needed. I'm not sure if TWRP prompts you about the recovery/root change.
[Nexus 4 General] alpha beta gaga:
is that even possible?! :D
[Nexus 4 General] donec:
That doesn't really tell much except to those that know what it means. So I'll also ask what do you mean sideload or adb sideload?
[Nexus 4 General] briansuperduper:
I'm stock, rooted, twrp recovery and did the following to update and retain root:

1. Download, install and run ota rootkeeper

2. Select backup root

3. Boot into twrp root recovery and flash zip file from post #3

4. Reboot phone

5. Open ota rootkeeper and select restore root

6. Voila!
[Nexus 4 General] CMNein:
A way to install updates.

Here's some info: http://teamw.in/ADBSideload

If I have stock boot loader, can i just use ota rootkeeper, and update phone OTA?
[Nexus 4 General] muyoso:
For some reason I cannot get my phone to do this. Rebooted about 2 dozen times so far.
[Nexus 4 General] nyijedi:
Suggestion for the future. Rather than deleting system .apks, simply rename them (i.e., I just add .old to the end). Then you can just temporarily rename them back when you want to apply an OTA update. This is good for certain apps that cannot be disabled through Settings/Apps.
[Nexus 4 General] yokken:
It's volume down. Not volume up.
[Nexus 4 General] jak3z:
I just installed this one with CWM, it warned me that in the next reboot my recovery would be go back to stock, if I wanted to fix that, I said Yes, and asked me aswell to keep busybox, told CWM that yes. OTA got installed and I still have root and CWM.
[Nexus 4 General] VivaErBetis:
OTA upgraded perfectly.

I have CWM recovery, rooted and with stock ROM.

I received the OTA via WiFi and it asked me to Install&restart. I agreed and CWM recovery starts and asked me to install the untrusted zip. I answered yes and the OTA was installed. At the end of the installation I choose "Reboot now" and CWM asked me if I want to keep it instead of new the recovery (answered yes) and asked if I want to keep root (answered yes).

And that's all. Absolutely perfect!

[Nexus 4 General] italia0101:
What is the screen flicker issue ? I've never had it
[Nexus 4 General] gtg465x:
It's rare. Only seen it three times in the past week. It's when you turn the screen on and the lockscreen is flickering. You have to turn the screen off and then on again for it to go away.

Hey,

I've never owned a nexus (have one coming) - I have a little question.....

If running stock, but rooted - do you 'have to' remove root before installing the OTA updates?

I know it won't stay rooted, just wondering if its necessary to remove it prior to installing an OTA.

If so, what do 'you' use to remove root?

Cheers guys.
[Nexus 4 General] MaxCarnage:
I think it's been said more than once that you can keep root installing the update...

Sent from my Nexus 4
[Nexus 4 General] mqguitar:
Well you can use voodoo root keeper. Follow the steps in the app. Then this is what I did.

downloaded OTA in post #3

installed CWM through rom manager

Rebooted into CWM

then searched for the file and installed.

And then rebooted.

It will give you options to keep CWM recovery and root. I decided no for CWM and yes for root. You can click no if you want for root and then just open up voodoo root keeper and restore root

Hope this helps
