In searching through the Development threads about rooting, I didn't really see a concise answer to this.
If I root using a method from Development - say SuperRoot from paulobrien, can I unroot back to stock say for warranty purposes? I'm all for rooting and trying the ROMs already out for us (thank you to those that have gotten this ball rolling fast already!!), but I've seen some low build quality issues from friends and want the ability to return this if necessary.
Google already has the factory images posted. Been up for a while. Flash em and relock bootloader
Download the stock Nexus 7 image and go into the recovery mode on your Nexus 7. Then extract the stock image file and the scripts inside the same archive. Use these scripts to restore back to stock, and use fastboot oem lock to lock it up when you're done.
Now it'll be exactly as it was from Google.
Even if you return to root, google can still detect that the device has been rooted.

When you stock and lock, there won't won't be warranty issues.

Alright, to start off, I apologize if there is a thread already on this (I searched but couldn't find anything).
I am a complete noob at rooting and don't know much about it. I plan on rooting my Nexus 7 in order to get Stickmount for additional storage on my device. My worry isn't about that, after I root it, how easy will it be to update it when a update for the Nexus 7 is released? I heard of stuff like flashing a rom with a updated software or flashing a modified firmware. Will tutorials be available for this when the time comes?

After you root, install OTA rootkeeper from the market. I assume it works with the Nexus 7, not sure why it wouldn't, but this keeps your device from losing root after an OTA. You can also install clockworkmod recovery and install any ROM you want which makes more sense considering this is a nexus device after all

i can confirm this works.
i tested out a few different scenarios last night.
booted up device, ran update, unlocked bootloader, put bad boot.img on
restored to factory, rooted, booted, used OTA Keeper, ran update, rebooted and root was gone. ran OTA Keeper to restore and BAM! root was back

I just looked up that app, it seems it's already integrated into SuperSu (that's the one I'm planning on getting). I just want to know if it's easy or not to upgrade the device once it's rooted.
OTA rootkeeper is on super Su ???

"The application doesn't support original Superuser and not SuperSU for a very simple reason. The same feature OTA protection feature is already present in SuperSU."
That's what it said on the app overview section.
SuperSU Premium has it and it worked for me on my T-Mobile G2x when I updated to new OTA. Don't know if free version has it
Sent from my Galaxy Nexus
I'm a noob to this type of stuff so if free SuperSU DOES have the OTA rootkeeper, does that mean I can update my device without any trouble?
If it doesn't, what methods can I take to update it without causing any damage?
Pretty sure its only in the paid version its called survival mode

OP: You should calm down. I mean that in the nicest way possible. This is a Nexus device. You can unlock your device anytime you want. You can simple re-root if you happen to lose root, there well always be a method. If you like to be on stock, you can just flash the updated stock firmware. Chances are someone will pack a nice stock rooted firmware within a couple hours of it being released, possibly before you even get a notification that there is a new update.
Sorry if I came out as panicky, it's just that I never did this before so I don't know what's right from wrong. Well I'm sure I'll get used to it eventually, thanks for the help.
I was wondering if there was any work being done with a pure AOSP rom or any other roms that will theme with a locked bootloader.
The answer is sort-of...
No, you cannot unlock the boot loader if you the latest ota.
Yes, you can root and install safestrap, then look for a desirable ROM.
The third option I played with is replace as many of the Motorola apps as you can with the aosp versions. It is dangerous, I only tried it with email and that worked great, but I moved on to contacts and totally screwed up the ROM forcing me to flash back to stock and redo everything.

There is a work around for the latest OTA hehehe
Flash the stock.IMG in fastboot with the toolkit. It will flash a compatible version where you can unlock and root from there.
If you want AOSP... Carbon ROM is the closest in my opinion so far...

There is a Root Toolkit here in one of the forums, look for version 1.20
By unlock I mean unlocking the bootloader. It is only impossible if you don't flash an earlier version of the stock.img.
Yes it is confirmed, that is how I am running Carbon right now

Yes, I had the .78 OTA and then I downgraded to a compatible version to get root then unlock and flash a custom ROM.
I don't know if my case was for some reason special but I also never got the "Boot loader is unlocked warning" either.

First backup your data and im not responsible if you cause the apocalypse
OK. chose option #1. It will flash a rootable version.
Next to root, choose option #5.
Next chose option #6 to ULOCK your bootloader.
Next chose either option 3 or 4 for a custom recovery. (I like CWM)
Have fun. that is exactly What I Did.

So just making sure, you were on the 4.1.2 ota prior to doing this right? Based on the notice posted on that utility thread, you are not suppose to use it if you were on the latest ota, which is the same one that locked the bootloader (unless stood corrected). So did you take a leap of faith and went ahead and did it even though it was warned to not do it, and did you ended up succeeding?
Was your phone bought new, or do you know if it's previous owner unlocked it before you got a hold of it, which would explain how you were able to, IF it wasn't used and modified prior?
Also, when you flashed the "compatible version" was it that you flashed the 4.1.2 update found in the utility or did you change it out to another image found here: http://sbf.droid-developers.org/scorpion_mini_xt907/list.php
Just wandering, because if so, this is phenomenal news for those who have do not possess the ability to unlock normally because they took the recent ota. I am sure that like everyone else, including myself, we just want to know if this is safe to follow or not, no pointing fingers or bad accusations.
Thanks

I believe you... Now the question is who is brave enough to take a leap of faith? I would love to unlock by boot loader to ensure I will get the latest Android versions moving forward. I don't trust Verizon to let an upgrade thru beyond 4.1.2. I would test your procedure myself, but I'm too dependent on my phone for work right now.
So... Anyone? Anyone? Be a hero folks, somebody take the plunge! Pretty please?

Also, I feel obligated to mention this, and i do it with a heavy heart... A few weeks ago I seriously screwed up my phone playing with the contacts apk, breaking my ability to view my contacts or dial a number. I got desperate enough that even though I was on .78, used the utility and stock image to revert back everything fresh. I was so relieved when I saw it worked despite the warnings and being a slightly older rom version. Once I did that, I'm 75% sure I did trying unlocking the BL before installing .78 OTA, and it did not work. I figured I had nothing to lose at that point, and when it failed I just shrugged and continued getting my phone back to normal. Sorry if this discourages any brave souls, but again I am not 100% sure I followed the same steps Mentioned in this thread.

Download this .zip file once you have flashed the compatible stock version and have root.
As long as it says status code: 3 in the bootloader you are unlocked
Ok guys here are the results, sadly I could not achieve unlock with a unmodified, unrooted Razr M :
1. Turned off and started AP Fastboot mode. Used mattlgroff's Razr M Utility to flash to Android 4.1.2 98.15.66.XT907.Verizon.en.US system image. The flash worked perfectly I was able to downgrade to ota prior before the locked bootloader.
2. Used mattlgroff's Utility to root my device (step 5). I was able to root the device with SuperSU.
3. Used the seperate motopocalypse program by Dan Rosenberg found here http://forum.xda-developers.com/showthread.php?t=2226729. It ran and rebooted to AP fastboot mode. I received the folowing errors:
"TrustZone target address resolved to 2a020a02"
"TrustZone write failed: -11"
This indicated that the bootloader TrustZone which is needed to unlock, was still locked and that it couldn't make changes to properly unlock the device.
So for the time being, this method to unlock the bootloader does not work. I am thinking about trying the 4.1.1 system image instead, but I fear that since the bootloader is its own entity, that those that took the recent OTA had the TrustZone patched to the point where it cannot be written to period, even on a lower firmware. The best thing that could happen is for a miracle to occur and an exploit to be found to write to the TrustZone again.

Hi, ExonakiDev...
Unlocking the bootloader alone won't interfere with OTA's. Aside from the inconvenience of the factory reset and data wipe contingent upon running the command fastboot oem unlock, your Nexus 7 will perform normally as it did prior to the bootloader unlock, and that includes OTA updates. Unlocking the bootloader just allows you to run fastboot commands.
With regard to TWRP...
I can only speak for myself on this; others have reported different experiences. For myself, on my Nexus 7, flashing TWRP has never interfered with OTA's. Usually what happens is you just loose your Custom Recovery after the OTA, and you have to fastboot flash it again.
With regard to Root...
Root under Jellybean 4.3 works differently than it did under Jellybean 4.2.2, and as a result, and in all probability, root will cause an OTA to abort. So, prior to accepting the OTA, you should unroot first. It's a relatively trivial matter to re-root again afterwards.
Hope this helps.
Rgrds,
Ged.
