Hi!
I want to root my Nexus 7 with unlockroot but I know that then warranty won't work anymore. But if I unroot then my warranty will work again. So my question is.. When I root my Nexus and when somethong happens (like not turning on anymore or etc.) then I can't unroot it? It means that warranty won't work and I have to fix it by myself or take it to some business who does things like this.
Just use one of the nexus toolkits and you can unroot or relock bootloader, whatever you want.
What toolkit do you suggest using? Because I just ordered a new 16 gb Wi-Fi version

As far as I know they are both as good as each other. It seems to be down to your UI preference. I use mskip's toolkit, but other's prefer Wug's.
So if my Nexus 7 is not turning on I can easily relock bootloader and unroot?

How would anybody do anything to a device that can not be turned on?
Perhaps you meant "won't boot", but who knows really.
If you experience a hardware failure or do something dumb like flash junk to the bootloader (or erase it without flashing a valid one before exiting the currently-running bootloader), then nobody here can guarantee you anything at all.
There have been a couple of reports on here of devices which developed apparent hardware troubles which did not totally brick the device (that is, the unlocked bootloader state could still be observed), but apparently wrecked things to the point that no currently known techniques could rescue the device or relock the bootloader.
Having said that, there have been even more reports of newbs doing stupid stuff and bricking their devices. Interpret that any way you like; I interpret it to mean the owner bricking the device is more likely than it being caused by hardware failure.
Until there is something like "nvflash" for the N7 (might never happen), the N7 should not be considered to be unbrickable (say compared to Samsung devices that work with Kies/heimdal).
good luck

Has there been a method created yet to root the Nexus 7 without unlocking the bootloader?
I'd like to load up some of my old settings from my last tablet but don't want to unlock the bootloader just yet...

I'm also kind of interested in this; my Moto Atrix 2 has a locked bootloader (curse you Motorola) but we were able to root it and get CWM on it pretty easily I think. I'm not at all sure how that worked, and I don't know if the root I gained was "optimal" (is there even a difference?). I'm interested also in seeing if there is a way to get root without unlocking for the Nexus 7 because I don't want to factory reset just yet.
Are you guys sure there is no way? Is it just a fundamental difference between the two devices that prohibits it on the Nexus?
If you unlock, root, install custom rom & kernel and then follow this tutorial to reset it to factory, can you send your device to asus without being discovered?

you need to unlock the bootloader to install custom roms etc. I'm sure you could root the device install a su binary and super user and then easily relock the bootloader with a single command fastboot oem lock. What exactly are you afraid of? It's super easy if you have android sdk installed.
I don't wanna void warranty... and I don't want the related factory reset.

You can backup everything using adb backup (okay there are some app you can't backup with that, e.g. Temple run or Subway Surf) and after unlocking restore the backup
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 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

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!).

Hey guys,
Just ordered a Nexus 4 online and waiting for it to be delivered. But had to ask a quick question, that is, how easy is it to brick the Nexus 4? And if so, can it be unbricked easily via software?
I am currently using a Motorola Defy + and it its almost unbrickable and can be recovered from any type of brick. So just curious

Flash the wrong kernel is a really easy way to brick your nexus 4,and the only i know
Yep worst you can do is flash a kernel or ROM meant for a different device, but even that can usually be recovered by using download mode.

You can easily recover if you have a nandroid backup though I think.
Fastboot erase bootloader will brick you pretty quickly
Sent from my Nexus 4 using xda app-developers app
In short, you really have to try to brick it. Even then, it takes some work to break it to the point that you can't fix it with fastboot. You won't hard brick it on accident. I don't consider a soft brick a brick of any sort when you can fix it in 15mins with fastboot.
Pretty much the only way to brick is flashing the wrong bootloader or flashing something that isn't a bootloader to the bootloader partition.
In a way yes. Although it isnt like samsungs download mode, it is kind of unbrickable if you do brick it you just go into the bootloader use a toolkit download the stock rom and it will do the rest for you
Thanks people. Much appreciated
There is a topic somewhere in these forums with a guide that uses a program called lgtool or lgetool (can't remember which)
Which even lets you recover from a bricked bootloader. Though it is a lengthy and technical process.
So at this moment it is physically impossible to brick your phone. Unless it is bricked from actual damage to the hardware

Yes there's a great guide by Gigadroid somewhere in the general section. Basically as long as you can get into download mode the phone can be recovered.

Yeah I don't understand why people view flashing a wrong kernel as bricked. If you can get into the bootloader in my opinion it's not bricked!
Bricked is when it's just that, the phone can only be used as a paperweight and doesn't turn on in any sort of fashion. So doing "fastboot erase bootloader" is what I call a brick, which you'd have to be really drunk or just a total moron to do. And flashing wrong bootloader, or being so lucky as to have a power outage in the spilt second it takes to flash a bootloader is one of those I view as brick.

Maybe because if you flash an incorrect kernel you can't boot into the boot loader? Just a thought.

This isn't a true fastboot command
But yes, this is a very hard device to brick, most everything is recoverable. But I'm sure there are plenty who find a way to do this, usually the ones who dive in head first and have bad luck.

Have you actually tried the command.
On the nexus 7 this was a valid fastboot command and there was a few instances of people bricking by erasing the bootloader then rebooting before flashing another one
It probably would be a good idea for Google to have removed the ability to erase the bootloader as there really is no need to erase it

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.
