4.2 --> 4.1.2 Without rooting

Basically is this possible, to go from 4.2 to 4.1.2? Mine is fine but my friend's Nexus 7 keeps shutting down.
Will a factory reset restore 4.1.2? Is there another way? Been googling for an hour, & I'm thinking it mustn't be possible with unrooted devices.
Thanks for any help
Mrs Hedgehog
P.S Please don't yell.

Not that I am aware of--I think you'll need to unlock the boot loader to then push the 4.1.2 image to it, but don't worry, its pretty straightforward with a little reading. Check the stickies for guides.
did the move to 4.2 occur via ota update?

Yes it was via OTA update. Bottom, she isn't going to want to unlock her device. Is there no way to put it back to how it was when she pulled it out of the box brand new? Even if she loses everything she would prefer that.
P.S Thanks for answering, appreciated.

Maybe she needs to think again. You can relock it as if nothing had happened!

Ok would Google know if she did that. Would it be like it was when she first got it? Say if she had to send it back under the guarantee? I'm shocked actually. I thought a factory reset would take it back to basics. I don't think she'll agree somehow.

Nope, it is like nothing ever happened. No-one shall know (nor care,quite frankly).
Factory reset is more like delete data and settings (and also all your photos etc, if you choose SD card) and return to factory state (I.e. the base OS, which is now 4.2 after the update). It does not roll back to the original OS from the factory, which could be several iterations back.

Wug's Nexus Root Toolkit is what you need.
Unlock, flash back to stock 4.1.2 and then re-lock.

Think I may just do this. But, will it keep trying to force the update on me?

It's Google that pushes the updates.
I've had no problems with 4.2 but if I do, I'll roll back to 4.1.2 and wait...

So I'd still get the notification to update to 4.2 if I reverted back.
But yeah, 4.2 isn't that bad. I do notice some unresponsiveness when clicking icons but other than that, pretty good.

I had to roll back to 4.1.2 on my Nexus 7. The tablet would not charge (didn't recognize the high-current charger) under 4.2. To stop the update notifications I installed FOTAKill (tablet must be rooted). .doc file with FOTAKill installation instructions is attached.
Really wish that Google would have an option for "Never" when it asks for permission to install an update.

Hi, I have a question, If I flash back to stock with Wug's toolkit would I receive the 4.1.2 update OTA or would I have to flash it manually?

If "stock" is before 4.1.2 then yes, you'd get the OTA update notification (which would unroot the tablet. You might as well manually flash 4.1.2.
My Nexus 7 "bricked" when I allowed the update from 4.1.2 to 4.2, requiring a complicated procedure to unbrick it. I suspect that the problem was caused by a "rootkeeper" app.

I wrote that wrong, I meant if I'm on 4.2 and flash back to the 4.1 original that first came with the device, would the 4.1.2 update come up OTA or would I have to flash 4.1.2 manually?

I think you have to update manually. OTA will offer 4.2.

Correct. The FOTA update would offer only the latest version.

On my new Nexus two separate updates were sent in sequence. First an update to 4.1.2 then another update (declined) to 4.2 a few minutes later. It was not a single update from 4.1.1 to 4.2.

Thank u for sharing this info, this saves me the trouble from updating to 4.1.2 manually.
UPDATE: So I went back to the initial ROM the device came with (JB 4.1.1) and Google quickly prompted to update to 4.1.2 (which is what I wanted) and now it asks me to update to 4.2 but I ignore that
Long story short, my Nexus 7 is back up and working flawlessly again!!

4.2..> 4.1.2 Without rooting
Have Nexus 7, stock, has been upgraded OTA to 4.2.1. Have an $80 app (Anywhere Map) which company is working on a fix to operate with 4.2. I use Linux and it appears you can upgrade manually with 'adb reboot recovery' then Power & Vol to get recovery menu. Posts have said simply use 'adb sidload upgrade_img.zip' or 'adb install upgrade_img.zip'. Simple enough. I've only gotten to the menu from which I can choose 'apply update from adb', but have done nothing. Posts have said simply issue the command and select reboot from menu after it installs. This should install new os version without removing apps nor sdcard info. (I have backed up the whole sdcard with 'adb pull' to my computer.)
I have 4.1.2, 4.2, and 4.2.1 images. What I would like to do is put the 4.1.2 on to use until Anywhere Map gets their act together for 4.2. But 4.1.2 seems like a minor update to 4.1 and I can't find that image at Google nor anywhere else.
So the question is as to whether updating with the 4.1.2 image will work or not. I have the material to root the machine manually but would prefer not to do it. This all looks rather straightforward from the many posts I've read, except with my reservations on the 4.1.2 update. Thanks for any comments.

question about 4.3 update

so before i had my nexus 4 rooted, and now i just updated to 4.3 via OTA.
do i need to do the unlock and root thing all over again from the beginning, as I did with 4.2?
BTW, where is the "thank you" button people have been talking about, there are posts i really to "thank" but i never found the "thank you" button. i might being dumb but plz do tell me.

actually i got a "fallen on the ground" Android while doing OTA. should i refer to any other upgrade method? or just choose wipe to factory reset?

Normally even with root, you can do an OTA update and it would be fine, but it seems that 4.3 has changed something and loads of people are having problems when doing OTA update while rooted. I would highly suggest doing a factory reset before updating to 4.3.

Seems I'm in luck (except for losing root). Coming from rooted 4.2.2 I installed the OTA without errors.
My build is: JWR66V, I saw there also is another build.
Is there a problem with only one build?

god my screen has been stuck with the big X for quite a long time. guess I need to do some bootload and wipe?

omg it just keeps rebooting after every 10 minutes of use. damnit

Wipe data. This happens.

Well there is only one OTA build I think. The other one you saw was probably the leaked 4.3 rom.

The problem was solved by a factory data reset with a Google Backup.

[Q] nexus 7 keeps restarting after 4.3 update

this is my first time making an account/posting on xda after being a long time reader and user. just need some help with my nexus 7 32gb WiFi (Australian model) i have loved this tablet and I have never had a problem with it, its unrooted and has never been dropped or anything like that, i updated it to 4.3 ota last night and almost instantly after that I have noticed it keeps rebooting itself like so many other people have problems with on earlyr versions like 4.2, please tell me what I can do to fix this, I can't find any straight help, my location is off and always has been, but I have noticed every now and again I would notice (on earlyr version) fused location would always stop working and ask me to force close randomly, that now doesn't happen but instead it retstarts, so do u think this could be the problem? any help would be awesome, thanks.

If you're having a problem with 4.3 you can try two things.
1. Revert back to 4.2.2
2. Try a rooted official stock ROM.

[Q] 4.4 KitKat is still not available for me OTA (11/17/2013)

Hello fellow N10 owners,
Unfortunately, the OTA KitKat update for my N10 is still not available for download.
I have reset the Google Frameworks app, but that did not work.
I am running Android Version 4.3 build JWR66Y stock rooted.
If you guys have any suggestions I would really appreciate it. Also, If you would know
how I could keep root after the update that would be awesome!
Thank you

Perhaps Google is waiting for Kitkat to be released on the new Nexus 10 before updatring the original Nexus 10.

There is no new Google 10 and seriously once you get KitKat on your tablet you'll wish you hadn't, the OS is like a giant phone and isn't geared up for tablets.

I disagree. With the exception of the PhoneUI settings screen it's exactly the same thing we had before with much improved performance and reliability. I'm so glad to get rid of 4.3.. Nothing but problems.

Maybe it's been pulled.

The full image is available on the Nexus factory images site. If you can't wait for the OTA, just download and flash that. Just remember to edit the batch file so you don't wipe everything. Here is the link.
https://developers.google.com/android/nexus/images?csw=1#mantarayjwr66y

Taking advantage of the topic, I'm from Brazil and me has not yet come to update my tablet version is also JWR66Y rooted, I need to get the root to update via OTA? Because I remember the last update to 4.3, when restarted I had problem with the boot image and had to use a tool to change the boot image

I waited, and waited, but gave up a couple nights ago. Seems to me, it should be like a voting system. The more manual update checks you do, the sooner you get it versus those that don't manually check. Those that don't realize the update is even or won't miss it for another few days.
Editing the -w out of the batch file was troublesome for me. The flag would complete and the tablet would reboot, but it would then hang on the nexus boot screen. Tried twice, but waiting a half an hour each time, I deemed it failure. Unexpected too since I had done a full wipe, factory fresh 4.3 the week prior.
Running the unedited batch with wipe went without a hitch. No biggie since I had done it recently.

Yeah, I updated mine with the factory image several days ago...I decided to go ahead and let it do the full wipe since I was reading that folks were having issues after removing the "-w" flag. Full wipe is probably the way to go anyway if want to avoid bugs.
For anyone interested who hasn't done this before, I found the instructions here to be quite helpful:

i just recieved it myself on my Android 4.4, it says "fixes bugs" which i haven't felt there was, but i guess it's not everyone that finds the bugs they fix, and maybe the performance will go up a little more, i will bench a little later, depending on how much i have to do at work

Yeah it's mostly under the hood bug fixes. There's no change log but one new 'feature' they found is that it will remind you to set up a backup account if you have multiple Google accounts on the device.

Great to see your investgation what will be updated. But my Nexus 4 has no such update, so it is not for all KitKat devices.

the factory image and the one that comes on OTA should be the same as far as i know.
but it was pretty easy to flash my tablet, it took a little bcs i had a problem but when i fixed that one it went smoothly and no issues at all.

anyone else's touchscreen get ridiculous after this small OTA? I never had issues, then we got that jellybean OTA to "fix" touch screen issues for certain people, which then proceeded to break my touch screen. then I got kitkat, and it's perfect again, no touch issues anymore.. now I got this OTA and this morning I had to press everything 5 times before it registered! I did a reboot and it went away, but seriously, if they broke touch again, I'm giving up on this tablet.

Where is the update located once it is downloaded, I'm trying to install it with TWRP.

Just got it via OTA (had side loaded KitKat before that). Made me lose root but that should be easily fixed.

I had side loaded 4.4, unlocked and rooted. I got the OTA notification and there was an error installing and now I'm stuck in a bootloop. When it comes up it has dead android with red exclamation point and says "No command."

Same thing happened to me. I got the OTA notification but stoopidly I had SuperSU in OTA survival mode. The update failed and I ended up at the 'No Command' recovery thing you are talking about.
I was able to fix it by manually flashing the /boot, /recovery, and /system partitions (NOT /userdata ) in fastboot using the KRT16S system image that can be found here (https://developers.google.com/android/nexus/images#razorkrt16s). Everything was okay after that - all of my user data was intact and I was updated to KRT16S :good:
