Hi, I just got a new Nexus 7 and I want to root it.
Every guide I look at it seems you have to lose everything on the device, is there a way around this?
Thanks!

Hi, zootylicious...
No, unfortunately not. Rooting requires unlocking the bootloader. For security reasons, unlocking the bootloader will perform a factory reset.... and which will wipe everything on the device.
There are currently no known 'root exploits' for KitKat... such as the old motochopper 'exploit' that worked so well under Jellybean 4.2.2... and rooted the Nexus 7 WITHOUT unlocking the bootloader.
Since Jellybean 4.3 and onward to KitKat 4.4.2, such 'exploits/vulnerabilities' have been 'closed' by Google.... so if you wish to root your Nexus 7, you're going to have to do it the old fashioned way...
----------------------------------------------
** Unlock the bootloader... will wipe the device.
** Fastboot flash a Custom Recovery (CWM or TWRP).
** Download to the Nexus 7, Chainfire's SuperSU root updater .zip
** Boot into the previously fastboot flashed Custom Recovery, and flash the SuperSU .zip.
** Reboot - you're rooted.
----------------------------------------------
Read the 'stickies' and the many excellent guides on this forum for more details.
Hope this helps.
Rgrds,
Ged.
If its new then I presume you have just installed lots of apps that you don't want to reeinstall. Google will "backup"apps and will automatically download and reinstall them when you set up the tablet again after bootloader unlock and root. The Bootloader can usually be relocked for warranty issues. You can use wugfresh nexus toolkit its pretty safe and easy to use.

Thanks for the replies.
I thought I'd just post an update on what I was doing.
I managed to root without losing anything by using adb to back up everything before I unlocked.

is there any method to root the nexus 7 without unlock the bootloader?
i read several posts about rooting n7, but every posts needs to unlock the bl first.
and "Flash Clockwork Mod Recovery" .
but i really don't know what the "cwm" is ! i want to use the stock nexus7 rom with rooted. is the cwm recovery will ruin something original?
could anyone solve my anxiety? thx!
You need to unlock the bootloader in order to root.
WugFresh's toolkit has a friendly interface making this extremely simple:
http://forum.xda-developers.com/showthread.php?t=1766475
Follow the instructions within the toolkit to ensure drivers are correct, backup apps, unlock bootloader, root device.
After doing this your Nexus will still be identical to stock.

Yep you need to unlock your bootloader to root.
You don't actually need Clock Work Mod recovery in order to be rooted.
In fact, I believe that the Wug Fresh toolkit posted by retrobeans above allows you to root and not install CWM.
Having said that, all CWM does is replace the stock Recovery on your device. This allows you to make backups, flash new ROMs and mods etc. If you never go into it, you will not notice a difference - you will still be running your stock rooted ROM. So i wouldnt be afraid of installing it . Or you can always do it at a later date if you want.
Bootloader can always be relocked with "fastboot oem lock" anyway...
why are you concerned about unlocking, or do you just not understand fastboot?

you can use a great toolkit by wugfresh which applies root without cwm. You still need to be unlocked though

is there any harm of being "cwm"ed? if not , i will try the easier way of one click root.(btw, i tried the wugfresh's toolkit ,but failed to install the driver...)
CWM (clockwork mod) is just a custom recovery image, from here you can flash files to your phone, wipe data, take full system backups (or restore).
Its a handy way to do key things people require when changing or modifying roms.
If in the future you will want to do any of the above then you will require a custom recovery.
Its not (in my opinion) the best recovery for the nexus 7 though, I use the Team WIN (TWRP) recovery.
You failed to install drivers? Or maybe when you installed Wug's tool it didn't download correctly? If you go and manually install the drivers which come with the tool I don't understand how they would have failed. Not trying to sound condescending or anything so sorry if I do. But Wug's toolkit (I know it's not the only one out there) is extremely easy and efficient. I would try re-downloading and on the driver install part go to
Right Click on computer
Manage
Device Manager, Here you should see a device either not detected or says that it's incorrectly installed blah blah
Right click the device and uninstall
at the top click on "Scan for Hardware Changes" (or something along those lines)
and right click your device when it comes up and the drivers are located wherever you installed his toolkit
I hope this helped and if not then just ignore. :laugh:

Get the pdanet drivers, cwm is just a custom recovery, for wiping data and caches. Just has a few nice options like backing up full system data and boot.img . No real disadvantage and you can always flash back stock

You can lock bootloader after.
You can get OTA but you would lose root and also lose your custom recovery, and with a locked bootloader you would be unable to root again

Sorry fellows, but you are wrong There IS a method to root the Nexus 7 without unlocking the bootloader.
Then you can have root without wipping your data, for instance, as happens when you unlock your BL. And with root you can unlock the BL without wipping your data too. All thanks to efrant with his awesome tutorials! It is in the Galaxy Nexus Forum, but me and some others have reported to be working on the Nexus 7 too.
http://forum.xda-developers.com/showthread.php?t=1894717 -- Root without unlocking
http://forum.xda-developers.com/showthread.php?t=1731993 -- Unlock BL without wipping
Let me sum it up.
Can i root without unlocking bl? yes.
Can i unlock bl without full wipe , when i do it the first time? no.
So u install pdanet drivers(i know, i had driver problems on my old win xp company laptop), then unlock bl, root. Thats it. u dont need to install CWM(btw, I prefer TWRP).
OTA updates n recovery: As far as i know, u will receive OTA updates whether u have CWM or not, but when u click install for the update, if u have CWM/TWRP, it wont install. It will install properly only if u have stock recovery.
OTA updates n root: U will get n will be able to install updates whether or not u have root. But u will lose root if u install the update. Re rooting is esy if u already have an unlocked BL, but theres an app "voodoo ota rootkeeper", that makes a backup of your root status b4 update n then restores it after update. N its free!! Nice, huh?
Unlocking BL shindig: So u would have 2 reasons for not wanting to keep ur BL unlocked. First, if anything goes wrong(very very very unlikely, believe me I have done a lot of crap on this phone, its extremely hard to brick), u need to return it in BL locked state. Second: Security. If your phone gets stolen n ur BL is unlocked, some guy could easily flash CWM n flash a custom rom n access all your data. For both cases, I suggest a very useful technique.
1.Unlock BL.
2.Root
3.Relock BL.
4. Install app https://play.google.com/store/apps/details?id=net.segv11.bootunlocker. This app will let u unlock BL from within a rooted phone without having to wipe your whole phone. If you are confused at this point, let me explain further, in case something happens to your phone n u need 2 return, u can just return it, if BL is locked, there wont b any issues. Also, if your phone is stolen, the theif wont b able to access it without completely wiping ur phone(unless he is a xda member n knows about that app!!! lol).
Got it?

I think The peeps who also agree twrp is much better than CWM is grown to the point where is the preimanant force for custom backup now. This Dev is 100% correct in my opinion also
Hi
First of all, this is don't habitual for me since I used to read related post (and more if an update has just arrived) but I just could not find an specific instructions (sorry if I am being too demanding) to go from custom 4.2.1(PA) to stock and finish with rooted 4.2.2, there are a lot of several procedures or recommendations to perform the update :S
well this is what I have planed
- return to stock 4.2.1 (using nexus toolkit)
- download and flash manually the update to 4.2.2 (first try to use the ota update option)
- get root... how??? lol
- restore my apps/data
Since I will return to stock I think I will lose root, that is ok but only if i can root the nexus again, Will I be able to get root on 4.2.2? or I have to root in 4.2.1 and keep it (in some way) at the time I update to 4.2.2

ok, I think I have missing that simple thing...
I don't have to worry about get the bootloader locked again therefore I just have to flash a recovery and SU when I have my N7 on 4.2.2, but...flash from... bootloader I guess, well, I will check that.
Thanks!
Learn the manual way of doing it and don't rely on toolkits. There are many tutorials walking you through the entire process

To elaborate on Pirateghost's points...
After flashing the 4.2.2 update... you will lose your recovery (CWM or TWRP)... but getting your recovery back is also part of how you (re)gain root.
As I have posted elsewhere...
Rooting is really simple.
(You will need an unlocked bootloader for this).
Get a custom recovery .img for your device...
Either CWM - http://www.clockworkmod.com/rommanager
...or TWRP - http://www.teamw.in/project/twrp2/103,
...it matters little which...
-----------
fastboot flash it.
-----------
Get Chainfires SU .zip package here http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip
Flash it using the custom recovery you've just fastboot flashed..
Reboot... and you're rooted.
-----------
...and that's it basically... you have root, a custom recovery from which you can flash ROMs, perform nandroid backups, etc.
But fastboot is the key... learn how to use it, and you will never need to be reliant on anybodies toolkit.
Rgrds,
Ged.
ive rooted galaxy s3 many times but ive been reading that there are problems rooting to 4.2.2
like any other nexus on any other version of android. fastboot oem unlock, fastboot flash a custom recovery, flash either the su binaries or custom rom in your new recovery, reboot and profit. thats all. theres never a problem rooting a nexus if done right, google lets you. dont use root toolkits, unless you already know whats going on.
It is quite a simple process. If you don't want to use fastboot, then you can use the Nexus Root Toolkit. Lifehacker had an article on this. To my knowledge 4.2.2 was difficult on tablets due to the multiuser, but that has been fixed with SuperSU and Superuser from Clockworkmod. The Nexus 4 has no such problems and should have no problem being rooted.

My 7 is unlocked and rooted, using Nexus Root Toolkit. I did an OTA to get to 4.2.1 some time ago and that went well. Root and unlock persisted. I am now getting OTA options for 4.2.2 from the System menu. First time I got and error in Android's belly. I restarted and was still in 4.2.1. System then said that I was up to date. A week or so later System told me again that OTA was available and I got the same result.
Any suggestions as to how I can do the update?

You have two choices
1. Flash the stock 4.2.2 image using fastboot from here https://developers.google.com/android/nexus/images
Or
2. Flash this in CWM recovery (note this link is for the wifi model) http://android.clients.google.com/p....signed-nakasi-JDQ39-from-JOP40D.6ece895e.zip
You have to restore everything except relocking bootloader ... To be able to update ...when u finish ..just re-root

assert failed_apply_patch_check("/system/bin/debuggerd", "a2323a0c8 and a lot more
This is followed by error in file
I saw something about busybox changing some system files.
Any ideas??
How do I unroot without whipping all data?

Search this forum for "OTA debugged"
There are only a few threads - read them all before you take any action.
This particular problem appears to be caused by StickMount.
You don't need to delete everything, nor do you need to flash the ENTIRE stock image - only the boot.img and system.img (via fastboot) without doing a factory reset or any other wiping.
This will unroot the ROM, and (of course) prevent StickMount from working. So you should over flash a SuperSU root kit afterwards (via custom recovery).
This very same problem may recur on the next OTA - so for goodness sake's, make a nandroid backup before you re-install StickMount and give it root privileges.

Sorry for being a numpty... can someone put the above into a mini step by step guide for me.. I'm stuggling with the terminology.
I rooted my Nexus and have since forgotten anything techie regarding it. I have StickMount and cannot update to 4.2.2..
How do i flash boot.img and system.img via fastboot, where do i get these files from, what versions etc do i need? And over flash SuperSU root kit?
What is OTA?
Basically, I think i need a newbie guide. I am techie enough to achieve most things normally.. i just don't know the android system at all, and what i did know to be able to root it i have completely forgotten!
Any guidance would be very much appreciated. Cheers.
Hello Guys,I would like to ask that am i able to root the Nexus 7 3G With Android v4.3 JWR66Y Locked Bootloader?
I don't want to unlock the bootloader,only want to root.
Actually i want to restore app data from other device that was rooted,i tried Helium Carbon app,but can't restore it on unrooted device because its file were from rooted device.
Or is there any app that can backup app's data without root ?
Thanks.

Not possible with Jellybean 4.3, I'm afraid.
Hi, Ben Ling...
There used to be a way of rooting the Nexus 7 whilst running Jellybean 4.2.2, without unlocking the bootloader... called the motochopper 'exploit' . But sadly, that method now no longer works under Jellybean 4.3... something to do with the security enhancements of JB 4.3.
I know of no method of rooting the Nexus 7 (whilst running Jellybean 4.3), without unlocking the bootloader first... as rooting typically involves fastboot flashing a Custom Recovery (CWM or TWRP) first... and you can't run fastboot commands with a locked bootloader (other than fastboot oem unlock).
The app I use for backing up apps and user data is Titanium...which you're probably already aware of... and of course, it requires root. Although I've never tried other backup apps, I suspect that root is going to a be necessary prerequisite if you want to backup and restore apps and their associated data.
Sorry I couldn't suggest anything helpful.
