i know the flash images for 4.3 are available now but wouldnt it be easier to wait for the OTA update? and the process will be simpler? or am i missing something? Also if I have a custom kernel but stock rom all I need to do for the OTA update is go back to stock kernel correct?

You will need to be 100% stock to get the OTA the normal way, otherwise you'll have to flash it manually via adb sideload or a custom recovery

so you mean like No custom roms, custom kernels or root apps? or root or unlock bootloader?
100% stock means exactly that. You can leave the bootloader unlocked but the main system itself has to be exactly how it was brand new as the OTA patches the original files. If they're not there the OTA will fail

If i upgrade to 4.3 with the factory image am i still rooted? Can i still use my apps that require root lets says auto hide soft keys?
You can get OTA update even when you have root (assuming you haven't touched any system files), but you will lose root after the update. It's pretty easy to re-root though.

I still dont have it via OTA yet.
Is it just the US at the moment ?
I am having some issues with an AOSP 4.3 rom. I would like to stay on 4.3 but with the complete stock rom directly from Google. Is it possible to have root on the ota stock 4.3 rom? I would rather be back on 4.2.2 stock/rooted than rooted 4.3 with too many glitches
Due to some security changes in 4.3 root won't survive an OTA. You'll need the stock recovery to update via OTA. Subsequently, you'll need a custom recovery to flash the latest version of SuperSU and have root again.
What's your current state?

I'm on a rooted 4.3 AOSP ROM with TWRP 2.6.0.0. Did a regular wipe while I was 4.2.2 before I flashed. Can you flash a custom recovery on unrooted ota 4.3?

Did you also flash the latest bootloader and radio? That's important, specially the radio (to avoid compatibilities issues with ROMs).

So theoretically if I revert to stock 4.2.2 I can update to the OTA, then flash a custom recovery (I assume I can do that via the toolkit?), then flash the root file, I'll be good? Do I need to relock my bootloader?

I'm not sure if these zip files are flashable, though.
I'd strongly suggest you to download Google's Factory Images from:
https://developers.google.com/android/nexus/images#occamjwr66v
And extract both from there to be safe (bootloader and radio images).
You won't be able to flash these images from TWRP. In this case, you'll need to use fastboot commands to flash them (but it will be safer, in my opinion).
If you're not familiar with fastboot command lines and don't have the Android ADT Bundle either please let me know, I can walk you through.
[EDIT] I found another link for the radio (a.k.a. baseband) and bootloader. Here it is:
https://www.copy.com/s/JniBu/4.3 files (mako)
I'm 100% sure these are proper versions but since they're images you'll have to flash them via fastboot.

I kinda wanna revert to 4.2.2 and OTA update to 4.3 so I can be 100% stock. I don't know if I can trust the dev who's making this AOSP ROM. Does my bootloader need to be locked to update?
bootloader will need to be unlocked. thats easy, you dont need a toolkit, you wont learn anything that way. you will need to install fastboot to your computer. you boot into your bootloader, connect to your computer via usb, start fastboot, open a command window, type.. fastboot devices(this is to check if fastboot sees your device), then type.. fastboot oem unlock(then look at your n4 screen to press yes or no). this will unlock your bootloader. download your recovery to your computer, stick it into the same folder as fastboot(do this before you start), then type in the command window.. fastboot flash recovery recoveryname.img(this will flash your custom recovery). then, in the bootloader, press your volume keys to scroll to the word recovery, press your power button to boot into recovery.

No, you don't need a locked bootloader to update via OTA.
Out of curiosity, how are you going to revert to 4.2.2 if you've never used fastboot command lines? You're in an AOSP 4.3 ROM right now, with 4.2.2 bootloader and radio. Do you have a flashable 4.2.2? That's the only way I can see it happen (unless I'm missing something which is probable).

I'd never suggest any toolkit because you won't learn anything from it. I'm not sure how's current state of toolkits so I can't comment on their proper functioning with 4.3.

Yes, it is. You can pretty much flash any baseband on stock or ROMs. The question is, is it worth it? It may work flawlessly but it could also cause issues. I'd do it but I'd keep my eyes on it if something goes wrong all of a sudden.
I have a rooted (no CWM changed) and unlocked Nexus 4 with JB 4.3.
I did not get the OTA yet and I wondered if it is because the phone is rooted. In addition, I read some problems with people who tried to update to 4.4 with rooted phones and are getting infinite bootloops.
Do I have to unroot my 4.3 for getting the OTA and achieving a successful installation?
Thank you all on advance

I am rooted and received the OTA notification yesterday. You 'SHOULD' be able to install if ALL you did was root. However, if you applied any mods that made changes to the system, the OTA will fail.

What I would like is to update to kitkat without losing my data.
I have the bootloader unlocked and the phone rooted, but when I go to recovery mode I get "No command" screen (is that normal?).
I was thinking of getting the phone unrooted, then update through the OTA, then root it again, just for making sure I don't break anything, but the "No command" screen does not look very good...
On the other hand, Would I lose my data if I "unroot" the phone?

To unroot, all you need to do is go into SuperSu, disable root, uninstall the app and then reboot the phone.
If all you have done is root the phone, and didn't modify anything else, then the OTA update 'SHOULD' install without a problem.
You can go to Android Police and download the OTA files and flash them via ADB, or you can just wait for the OTA to be pushed to your device.
If you decide to do it the manual way, there is one additional step you must take to ensure to keep your data I believe.

Thank you for your help gbarayah, I really appreciate it.
One last thing: I'm not pretty sure the only thing I modified was the rooting. I did not install any zip to modify my stock version, but there is something weird. I will explain:
At first I had 4.2.2, then I rooted and installed CWM. When 4.3 was released I got the OTA update correctly but I lost the root, so I rooted it again, this time without CWM.
Is the "No command" screen what is supposed to appear when I go to the recovery mode from fastboot menu? Or I would get a default recovery mode program?
If everything is right I will unroot for getting the OTA, but if not, I'm afraid I will have to flash CWM and the stock version, loosing my settings...
EDIT: Ok, I've just realized to get into stock system recovery I have to press VolUp and Power buttons once I'm in the 'No Command' screen, so I'm pretty sure I don't have problems installing the OTA update. Thank You!!!

Glad I could help. In the future, as long as you don't modify the system by flashing any modifications, you should be able to get the OTA update to install. Root doesn't affect this, and if you're worried about it, you can always uninstall it.
I opted to update using the stock zip files that were posted above and it worked just fine for me.
Is there a way to downgrade from 4.4.2 to 4.3?
You can downgrade via downloading the Stock 4.3 files from the SuperTool site by tom and flash that via fastboot. But be careful you can brick the tablet.

Any experience? I'm interested too to downgrade to 4.3.
If you have OTA'd past 4.3 its just a simple download the images from toms server for 4.3 and fastboot flash them.
You can get the stock 4.3 images from : http://rootjunkysdl.com/?device=Tegra Note 7&folder=Roms Stock 4.3.
These files here is infact CWM/TWRP flashable zips so its just a case of unlocking the bootloader and flashing either CWM or TWRP then placing the stock 4.3 rom zip onto a SDCard and flashing it.
But before you flash the zip make totally sure you wipe the following partitions
Boot
System
Cache
UserData
This will downgrade you back to 4.3
In TWRP i can only wipe system,cache,data but not boot.
Ok wipe what you can the flashing of boot.img should wipe it before hand. Goodluck
@subzero82 How did it go with the downgrade?

I don't know if it apply to our device but it mean (on the readings) that KitKat suffer of a serious bug : The OS doesn't let some apps to go to deep sleep and the Wakelock are terrible.
That point and some others (more personnal) make me think to revert to 4.3
there is nothing on nvidia's offical site, I dont know if they are still supporting the device to fix this issue. I will try reverting to 4.3 and see how it goes, The nvidia shield has the same issue in 4.4

And do you think after downgrade, the CWM backups are compatible? I mean : I want to be able to restore 4.3 or 4.4 as I wish in order to do testings?
@chp2 if your afraid of bricking your tablet then why are you after downgrading your tablet in the first place.
Look its format
System
Cache
UserData
Then flash the 4.3 Stock zip and boom your on 4.3. CWM backups will still work regardless of what OS your so long as your using the Custom Recovery.
But as i said if your frightened of bricking your tablet you shouldn't be doing this.

LOL, But thanks for your help.
For me the TN7 is new and since I'm not yet familiar with it I prefer to be carefull.
And I prefer to ask before doing bad things. Perhaps in some days I'll laugh of it
LOL, i understand what you mean. But for me it was first day i got it, I rooted it and was messing with APX off the bat. Yes my first one failed because of faulty hardware so i got it replaced and yet again i Rooted it and started messing with going back and forth between 4.3 and 4.4.2.
Everything will break at one point in its life time. Tablets and phones are there to be abused mate,
If you end up in a reboot loop so long as you have your 4.4.2 backup your can just restore that and your be working again. If you brick you have APX to fix it.
Hello.Succsesfull downgraded from 4.4 to 4.3 after hour of fighting,couple of restoring backups,using supertool 1.5(i dont know does it help,nothing was happening).I was using hacktrix2006 instruction.
@ZubZero82 So you ended up flashing via fastboot then ??
I think that supertool maybe change bootloader and flash zip through twrp.
Update
Flashed 4.4 zip through TWRP,cleared System Cache UserData ,restored bacup of 4.3(error if try to install stock 4.3 without restoring),flashed stock 4.3 zip.Thanks for help.

Finally.
I managed to downgrade to 4.3 and to block OTA popups.
I got some thrils when I had to re-install CWM but everything went ok.
Until now, no problems to report.
Thanks again hacktrix2006 :good:
no problems. I hope you just chmoded the file TegraOTA.apk in the /system/app folder (I think it was there)
If not the best way to disable OTA's is using the following command as SU
chmod 000 /system/app/TegraOTA.apk then reboot the tablet.
This will then keep the file there but make it so that it can't be read wrote to or even execute. Then if you want to OTA again you just change it back to chmod 644 /system/app/TegraOTA.apk and reboot again.
Hi
I am running on LMY47V, Version 5.1.1.
About 2 days ago i got an update of 20 MB which got downloaded into my device but failing to apply.
Whenever i Click the Restart and Install button the device gets restarted and goes into ClockworkMod Recovery v6.0.4.7 asking to fix the root access which is possibly lost . I tried both the options Yes and No then the device gets started with no update.
Then the same notification comes in asking me to Restart and Apply.
I have rooted and applied CM Recovery recently and this never happened to me before rooting.
It is normal that OTA updates do not work when rooted. There are a few workarounds, but they are not super easy (you can normally install the updates manually using adb-tools if I remember correctly).

Yeah, to use the OTA updates you need to be completely stock. Stock ROM, locked bootloader, no root and stock recovery.

I cannot say enough good things about this Nexus Root Toolkit by WugFresh: http://www.wugfresh.com/nrt/
Made it super simple for me to flash back to stock, get that OTA update, and then flash TWRP right back (so that I could enable 4G/LTE again).

I strongly recommend you learn how to use fastboot. You would not have had to flash back to stock to update. You could have flashed the system and boot images and been done with it. NRT is a good tool but you have much more flexibility if you understand what you're doing with fastboot.
