Root Nexus 4 with motochopper - Nexus 4 Q&A, Help & Troubleshooting

Appreciate if someone can advise if it works or not. Thanks.

Why you want to do that with a Nexus device?
Want root?
fastboot oem unlock

Don't want to unlock bootloader as it will reset everything.

yes it works
I did it in a friend's phone, as she didnt want to lose data and I was lazy enough to not make a backup
just make sure adb is working properly...
My pc didnt recognize her phone immediately, adb was saying device was offline
after updating adb everything went ok

You can root it with motochopper and then use the bootunlocker app on the play store to unlock the boot loader without using data.
You can also do fastboot OEM unlock, and flash a recovery with fast boot. Clearing the cache in recovery should stop you losing data, theres a thread in the general section that tells you how to do this

Great. Does root affect future OTA update?

Is there any method to root the Nexus 7 without unlock the bl?

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

[Q]Rooting N7

Hi,
Can you just root the N7, without loosing all your data?
I just want to be able to root it so I can use USB OTG properly.
With StickMount etc.
I don't want custom ROM's etc, just plain old root.
Any way to do this without loosing my apps/layout/data etc.
THANKS !
In order to "just" root, at a bare minimum, you will need to install su. In order to install su, you need to flash a custom recovery. To flash a custom recovery, your bootloader must be unlocked. Unlocking your bootloader erases everything unless you are already unlocked.
There might be a way but it involves relocking your bootloader before booting to the system. Booting the system in an unlocked state causes it to erase everything. All rooting operations can be done without booting the system and the last step would be to lock the bootloader. I have not tried this so no guarantees.
In order to root, you need to unlock your bootloader which will wipe your N7 app layouts etc. You can use adb to backup your apps and settings, or you can have a toolkit do it for you. Unfortunately, I can't help you with exactly how to backup. I didn't backup my settings when I unlocked my bootloader because I did it soon after I got my N7. I'm sure there is someone on here that's more knowledgeable in adb that can tell you the right commands.

Thanks both, what about the "All-In-One" nexus toolkit, I think that has a backup function and stuff.
And I guess this is a note to self "Root" before you customise and get all set etc.
I wouldn't even root it if I didn't want OTG but things have to be done I suppose.
Can any1 shed any light for the easiest way of rooting, and keeping my apps etc, because its such a ball-ache setting it up again

In need of Help (Root) won't boot

Hello,
So, I got my Nexus 10 today. Super nice tablet. I wanted to root it and unlock the bootloader - unlocking the bootloader went fine, and I managed to flash CWM recovery. However, I forgot the enable USB Debugging under developer tools before I started all this..
My question now, how do I get this thing to boot again? And what is the smartest move now to root it?
Thanks!
What method did you use?
I keep linking these same posts lately. lol

If you're stuck in a boot loop after unlocking the bootloader, you may have to perform a factory reset from recovery. I had to do this to get mine booting again after I unlocked it. After the reset, everything worked great.
Of course, this is also assuming you unlocked your bootloader using fastboot , and not a toolkit. Solution might be the same though either way. May be worth a shot.
I also borked the original ROM after unlocking it, before I even flashed a custom recovery using the nexus toolkit (http://forum.xda-developers.com/showthread.php?t=2015467)
However, it is quite easy to reflash the software (you will loose the data though) through the same toolkit. After that I was able to flash TWRP recovery and CM10.1
Thank you all for your help! Got it working using the linux toolkit and perform a factory reset

[Q] Does Custom Recovery require a prior bootloader unlock?

Is it possible to flash twrp .img using flashboot without first unlocking the bootloader...
move the SuperSU .zip over to internal SD
flash with TWRP
and then install bootunlocker
I ask, because I dont want to lose all data by
Code:
fastboot OEM unlock
command and I am not sure if a custom recovery requires an unlocked bootloader (I assume recover is still strapped to initial handoff of bootloader)
Also, this seems both safer and more convenient than leaving bootloader unlocked after customizations... or locking and restoring backups
I'm quite sure you would have to unlock the boot loader before flashing a custom recovery, although there may be some way around it that I'm not aware of.
If you want to save your data just copy it to a desktop computer before unlocking then copy it back when you're done. Of course, without root you will have to reinstall your apps.
No need to unlock just use the Superboot - Nexus 10 root solution then use something like ROM Manager to install CWM. Worked for me so now I have a locked rooted nexus 10 with CWM.
Yeah... I just wanted to do it the old fashioned way and get dirty...
but as suspected, when trying to flash recovery image via fastboot, I get the old locked bootloader routine.
This is why the first thing to do to a Nexus is to unlock its bootloader.

Granted... There is a way to root without unlocking, but it requires dicey operations with partitions that could result in a fancy paperweight.

Relock Bootloader with Nexus Root Toolkit

I have a 6P running 7.1.1 that has never been rooted or modified in anyway other than unlocking the bootloader. When I first got the phone I unlocked the bootloader so I could root the phone later if I wanted to without wiping the contents. I never rooted it.
Now Android Pay doesn't work with an unlocked bootloader. I would like to relock it. I understand that this will wipe my device. My question is, can I just press the button in NRT that says "OEM Lock" and it will take care of any flashing or resetting that needs to be done? I was more up to speed on all this when I had my Nexus 5, but the 6P hasn't really required me to get that involved.
Thank you for any help or advice.
Yes, OEM Lock will work, it just sends the ADB commands to your phone. Yes it will (unfortunately) factory reset the phone so to be sure to backup what you need, or at least be sure the Google backup feature is enabled for your apps.
Couldn't you just flash a custom kernel to get AP working again? For example, ElementalX has the bootloader check removed from the kernel. Use fastboot to boot into latest official TWRP without flashing it to the device and use that to flash EX kernel.

Thanks for the feedback. I knew I was going to lose everything, I just didn't want to brick it someway because it was 7.1.1.
