Stupid me didn't make a backup and flashed another ROM. How do I flash back the stock ROM, enabling me to get OTAs but maintain root? I want the original stock ROM...

Not really much of a point having the ability to get OTA when a new one comes out, a dev will do what is below shortly after anyway. OTA's are over rated..
Android OS, 4.1.1 Jellybean build JRO03D
Insecure boot.img
Rooted with the latest superuser
Busybox
Deodexed and Odexed options
Fully Zipaligned

Note that the downloads apparently don't work at the moment.
If you used the nexus root toolkit, it has the factory image there for you to flash back to stock and/or unroot/relock the device. Windows users only. -Ara

So is there no flashable zip for stock? I am a Mac. I rooted on my little brother's PC but he lives 1600 miles from me.

Did you take a look at the [Guide] Returning to Stock and/or Unbricking your device directions in the Nexus 7 Android Development forum?
If using a Mac, see the following link for setting up ADB/Fastboot drivers on Mac OS X.
How to Setup ADB and FASTBOOT Drivers on MAC
Edit to add: Factory image for the Nexus 7 can be downloaded at this Google link.

Hi everyone I was just wondering if its possible to downgrade my nexus from 4.2.1 to 4.1.2 if I'm not rooted. I'm currently not interested in rooting my device so is there a way to do it without rooting/unlocking?

I can't flash things because I'm unrooted. So I don't think this method will work. Correct me if I'm wrong.

I do not know for sure but I quite doubt it.
I am curious as to why you want to though. Not that there's anything wrong with wanting to downgrade, of course.
Have you tried one the took kits available? Check around in the Nexus 7 original development section. Look for Wuggs.

I looked at his toolkit but it basically says that I have to root in order to even use the toolkit so is there a way to downgrade without having to go through that rooting process? For now, I don't want to root my nexus
Sent from my Nexus 7 using xda app-developers app
Don't try to root it you'll only manage unlocking the boot loader then when you try and root it it will get stuck in fast boot mode I tried about every rooting program but it could be because my Comp is running windows xp lol

It's so easy to just reflash stock and relock the bootloader that you really have nothing to worry about. If you want unrooted stock 4.1.2 just unlock the bootloader, then flash the stock image of 4.1.2, then relock the bootloader after. It's a really simple process.

If i'm not mistaken, as long as you flash back to 4.2.1(which is the os it came with when u got it out of the box), and then re-lock the bootloader, unroot, then your warranty wont be voided mate. hope I helped.

Yeah, I've done this plenty of times with my Nexus 7 and even the Verizon Galaxy Nexus. As long as you're on a stock image with a locked bootloader, they won't give you any trouble or claim you voided your warranty, as there's really no way to tell. I've gotten into the habit of unlocking and rooting my device as soon as I get it, and if I find a problem I just revert back to a stock image, relock the bootloader, then send it back in. I have yet to have a single issue.

You don't need to worry about saving your stock image. The person above you is talking about saving the stock image to return to after flashing a custom ROM.
There is no way to revert back to 4.1.2 without root access. Doing a factory reset, about the only thing you can do without root, will only return you back to stock 4.2.1
My advice just stay on 4.2.1 whatever your issue is with it.
Otherwise use a toolkit. You will need a PC and the 4.1.2 image. Wugfresh has a website. I would start there.

I actually was just referring to the stock images you can get directly from Google or from goo.im. It's easy enough to just use the 4.2.1 stock image from Google to just restore back to how it shipped, and then relock the bootloader.

Completely agree with this... I have, on several occasions, reflashed stock, switching between 4.1.2 and 4.2.1 - (for me, it was more of an exercise in learning about fastboot and adb... and making sure I had TRIED AND TESTED factory images on my laptop as contingencies should anything go wrong when I came to start flashing custom ROMs).
-----
You don't need root to flash a factory image... everything is done with fastboot; with the Nexus 7 in FASTBOOT/BOOTLOADER mode (from complete shutdown, press and hold Volume Down button... whilst holding, press the Power Button).
(Root is meaningless anyway, here in FASTBOOT/BOOTLOADER mode, since /dev/block/mmcblk0p3, the SYSTEM partition, hasn't even been mounted yet - so no SU binary available... whether or not it exists, it's sort of irrelevant).
- here, for example, is the flash-all script from 4.1.2 (nakasi-jzo54k)... (Nexus 7, WiFi model only).
Code:
fastboot erase boot
fastboot erase cache
fastboot erase recovery
fastboot erase system
fastboot erase userdata
fastboot flash bootloader bootloader-grouper-3.41.img
fastboot reboot bootloader
sleep 10
fastboot -w update image-nakasi-jzo54k.zip
After running this script (flash-all.bat if in Windows, or flash-all.sh if an Apple user) you can optionally choose to lock the bootloader with... (if you're concerned about warranty issues).
Code:
fastboot oem lock
-----
If it was the case you needed root to run...
Code:
fastboot flash [partition to be flashed] [IMG file to flash]
...you wouldn't be able to flash a CUSTOM RECOVERY like CWM or TWRP... and thus, you wouldn't be able to flash Chainfire's UPDATE-SuperSU-v1.00.zip (http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip) in order to gain root in the first place!... (you see the paradox!).

No you're fine. I just got mine yesterday and naturally the first thing I did was update. The steps to unlock the bootloader and flash a recovery (or SuperSU, if you want root on stock ROM) are the same regardless of Android version.
EDIT: Also you DON'T NEED TO ROOT to use ROMs—all ROMs come with root already built in. Skip everything to do with rooting, unless you're trying to root and stay on the stock ROM.
All you need is to unlock the bootloader (ridiculously easy) and flash a custom recovery (also super easy). Then, without root, use the custom recovery to wipe and flash your ROM (which has root built in) and gapps.
Just began the RMA process with Google Play by ordering the replacement device. Now when I send back my faulty unit when the replacement arrives, in what state should I leave the software of the phone so that the RMA process finishes smoothly?
I'd imagine I'd have to flash stock rom+kernel, stock recovery, relock the boot loader, unroot, and possibly reset the flash counter (have no idea how to go about this last one). Anything I'm missing/feedback?
This is my first time going through Google's RMA process and I want it to happen as smoothly as possible. Thank you.

Nexus phones dont have flash counters. All you need to do is flash the stock images and relock the bootloader.

I want to root my Nexus 4 and install newest CM. One problem is, that there is Android 4.4 update comming soon. So if I root my Nexus and install CM, can I get my phone back to stock and update Android to 4.4?
Yes. You can either flash the 4.4 images, or simply install a 4.4 based custom ROM (the more practical solution my opinion) since you will already have installed a custom recovery.
