[Q] Encryption and root

I ask forgiveness if this has been answered before, but the search function is currently down.
I'm receiving my GSM GN tomorrow, and I'd like to ask a couple of questions, in case anyone has done this with their phone:
I work in a corporate environment that wants encryption on their mobile devices due to the nature of our work (insurance). My ICS tablet, an ASUS TF101, has the ability to do full device encryption, and I'm assuming that the GN can as well. However, I'd like to root my phone as well. This means that I will need to remain stock (which I have no issues with) and also need to keep the stock recovery. I'm not overly interested in running custom ROMs.
Is it possible to root the phone without replacing the stock recovery via an exploit?
Is it more practical, or realistic, to instead:
Unlock bootloader
Install CWM or equivalent recovery
Root device via recovery
Reflash stock recovery
Encrypt device
With my tablet, I rooted it before I encrypted it. Since it did not have an unlocked bootloader or recovery, I had to use one of the exploits that was around at the time.
Anyone have any advice they might share?

With an unlocked bootloader, you can boot whatever kernel you want without flashing it. So, just boot cwm, flash the root files, and done. You have root + stock recovery. Then you can turn on encryption.

Ah, unlocking the bootloader allows you to flash anything you want via the stock recovery? That's quite useful, and I appreciate the response

No, you can flash whatever you want in recovery regardless if your bootloader is locked or not.
What an unlocked bootloader allows you to do is flash whole images to partitions and to boot any kernel you want, using fastboot. So, you can boot up cwm without flashing it: fastboot boot cwm.img

Return to Stock - Without USB?

Hi folks. First post here and a bit of a weird one, I’m hoping some of you with more experience in rooting etc can point me in the right direction. I’ve got a GSM Galaxy Nexus which I previously rooted to get updates as I was stuck with some horrible build that had to go through Samsung and my carrier to update.
Now my USB port is faulty and I want to get it serviced under warranty but I don’t want them blaming the root access and trying to squirm out of it. I’m actually running a stock ROM of ICS so I don't need to change that - but I still have CWM installed along with its custom recovery mode(?), Superuser and the bootloader is unlocked.
Can anybody give me some suggestions on how I could undo this, preferably limiting my use of USB or eschewing it all together? It’s so unstable I’m really afraid of bricking the device. I want to just make it look as stock as possible so things go smoothly with the service or replacement.
I found suggestions in some threads for using 'Mobile ODIN'. Can anyone tell me if this would help? Thanks!

I've read on here multiple times that they will repair it even if rooted...maybe someone can confirm.

I think there is a apps on the market called adb wireless... May be it can help you!

Just get a stock ROM zip and you can use glados app to lock the boot loader when rooted then flash the stock fw after wiping system the stock system will wipe the custom recovery on boot enjoy

[Q] Only Root Galaxy Nexus without erasing any data

HI,
I've using my Galaxy Nexus (GSM) for a long time, but i want to get Root access, i've been reading a lot and it seems if i use Galaxy Nexus Toolkit it will delete all my data, there's any way to root it without losing any data?

no.
you have to unlock your bootloader (no matter which method you use, also, dont use a toolkit, use the sticky at the top of the forum) which wipes your data. period.

I did a root of my Galaxy Nexus, when I flashed the new 4.1. It did work fine. When the phone did the small update to 4.1.2, can it be true that it rolled back the root? My phone don't seem to be rooted anymore.
Isn't it possible to get root permissions again, without loosing data?

if your bootloader is unlocked, reflash the supersu.zip
otherwise, you have to unlock the bootloader and it will wipe your device.

if you enter fastboot, it will says "lock status: unlocked"
or you can see if when you first start up your phone if there's a little lock that is unlocked.

Similar thing happened to me. I was messing around with different ROM's for some time but in the end went back to the stock ROM. My phone now shows unlocked and using the stock recovery (as described here http://forums.androidcentral.com/google-samsung-galaxy-nexus/243004-recovery-mode.html).
The stock recovery offers 4 options: reboot, apply update from ADB or USB, wipe.
How do I "reflash the supersu.zip" from here? I want to avoid wiping as everything is set up as I like it now, and because it isn't rooted I can't back it up, catch 22 thing

I'm sorry, I didn't know there was a rule against that. I searched Google for the problem and this thread came up closest.
Well sorry if I am not a genius like you who know everything already. I thought that forums like this was for asking questions.
It would be nice if instead of just being mean and nasty you'd offer some constructive suggestions, such as would installing a custom recovery wipe the phone? The distinction between the boot loader and the custom recovery isn't clear to me.

Sarcastic, aren't we? Look, XDA is first and foremost a developer site for developers to develop. Answering and asking questions about that development is only incidental. Members are expected to have read the rules of XDA and to follow them. That includes not bumping old threads, but it also includes an expectation that you will read the information readily available to you. Seeing the same common questions get asked daily, when there are good guides made specifically for this purpose, gets very old very fast. The constructive suggestion is to search and read. Guides abound both in the stickies and elsewhere, and the fact that you haven't found answers to your fairly common questions tells me that you either haven't made an effort to look, or you just don't understand and therefore probably shouldn't be messing with your phone.

I was able to root my gnex without wiping the data!
I dont know how it happened, but it happened, I was surprised too because I was really frustrated couldn't root it even after 10-15 tries ( I am a big time noob) and suddenly I unlocked the boot loader and rooted the phone without any loss of data, actually I was rooting because I had the VM100U something memory issue and my phone was terribly slow! I was surprised becasue i was expecting to copy all my files and crap one by one but now I have no issues

[Q] How to root my Galaxy Nexus but still get OTA updates from Google?

Excuse my complete noobishness, but can someone help me root my Galaxy Nexus but still get OTA updates from Google? I found multiple sources from here and a video from QBKing77 but nothing answer my question completely. I would be really grateful if someone with experience could help me by give me step by step instructions.
Thank you.

Rooting your phone does not disable OTA updates.

Why would you want ota if you rooted? Just flash a rooted version of the updated rom when it's released.

That's what I do. I don't flash ROMS, just use a few apps that require root. Install OTA Root Keeper from the play store to retain root. Run the app before installing any updates to preserve root. Then when you receive an OTA, install the update then run OTA Root keeper again to get your root back. Worked for me on Verizon Galaxy Nexus coming from 4.0.4 to 4.1.1.

Only change would be fastboot boot recovery cwm.img rather than flash.

Just root the phone, and don't flash any custom recovery, then download supercurio's OTA root keeper app from the playstore, to backup your root then enable root with the same app after you receive OTA

Don't use the toolkit?
Sent from my Galaxy Nexus

Why not?
The toolkit is SUPER easy.
Open the tool kit and the DOS window guides you through what to do, by typing numbers or letters to get the desired option. I can post the guide on when to boot in recovery mode and what the phone will do but as for the Toolkit, it's self helping. Just install it, run it and follow the on-screen instructions.
I do exactly the same as what you want successfully; I have a completely stock Nexus, but it's rooted for the use of some apps. The OTA update tells me when there is an update, I install then simply root again. I'd rather not have an app to keep root as that will be yet another app to clog up my phone's app drawer.
A lot of the custom roms aren't to my taste so I am happy to keep the stock experience
Will post again the steps when I am on my home PC.

simply because the toolkit is an excuse not to learn the FUNDAMENTALS of owning a nexus device.
what happens when something goes wrong? do you know what the toolkit is doing behind the scenes? most of the toolkit users DONT. there are more than enough 'HALP!1!1 I BriKt mah PhoneZ!1!!oneone' to prove this is the case....
if you understand what its actually doing, you understand how useless it truly is...

Well, for starters the "fundamentals of owning a nexus device" don't include rooting at all. I know many people who use Nexus devices un-rooted and are fine.
Plus, I'm more than happy not learning too much about it as I'd rather spend my time eating cake.
Remember, not everyone here is in to tweaking settings, trying different radios, resetting their phone every 5 mins to test yet another ROM.
Some people are more than happy with the stock experience but just want root. The toolkit makes that simple.
Secondly, if the toolkit was doing things behind the scenes, I'm sure someone would have found that out and reported by now.
Thirdly, how do you know custom ROMs aren't doing the same thing? They are far more likely to be able to phone home without the owner knowing.
Fourthly, I personally tried rooting the manual way but the one line help of "just type this" I got never really worked with my phone.
Fifth, I've used the toolkit on my own phone and my partners many times, I've seen nothing bad, no bricking.
Don't see why you're so against something which makes life a lot easier for people who aren't too sure how to root the manual way?

And yet another person who fails at grasping why XDA exists....
Sent from my Galaxy Nexus

Actually, I do. I understand why XDA exists but I also understand the multi-uses it really has.
Not everyone who comes here has a desire to mess with their phones all the time...
If you're not a fan of the toolkit, why not flame the developer?
Here's a short guide on what the OP wanted to do.
1) Make sure phone is up to date. Make a note of your software version - probably 4.1.2 or 4.2 and build number (mine is JZO54K)
2) Turn on USB Debugging (Settings > Developer Options > USB Debugging)
3) Shut down the phone
4) Start in Bootloader (power button + vol up + vol down)
5) Run the Galaxy Nexus toolkit
This is where we use the toolkit. Read the info and select your build number. The windows will guide you through what options you have. If you want to root only, choose that option. Go through the menus and type YES to begin.
6) Phone will restart
7) After ~160 seconds, ToolKit will restart to Bootloader
8) Phone will restart
9) Toolkit will finish rooting by pushing the files to the phone.
10) Phone will restart back to Bootloader
11) Finish - Confirm in ToolKit
See pictures for further info.

Toolkits are pointless. It takes longer to learn the toolkit than it does the three commands needed to unlock and root a nexus. That's my ****ing point, yet this guy is going on about how easy the toolkit is to use. If it's so ****ing easy, why did you have to provide screenshots and instructions?

i cannot believe that someone would actually think its NOT beneficial to understand the process, and rely solely on a toolkit...its amazing to think that there are people so wrapped up in their own little minds, that they refuse to take the time to learn to do things the right way and understand what they are doing to their device.
what happens when joe user, who only knows the toolkit, flashes a mod on his phone that was NOT intended for his phone/build/rom version, and he bootloops? he jumps on xda and posts a thread. HALP I JACKED MAH PHONE!!! how do i fix it with the toolkit?

Don't use a toolkit. Learn commands yourself and you won't have to worry about what a toolkit is or isn't installing.

root toolkits are fine, if you already know what you are doing. the problem with root toolkits arises when a person that has no idea what they are doing uses them and messes something up, which happens often, just read all the threads that users start asking for help, that include the words "i used a root toolkit". you dont see any these thread with the words i used fastboot or adb. usually what happens is something simple gets messed up, then the situation becomes worse because the user didnt know/learn the basics, and messed something up after. this is the problem with root toolkits, they go around you having to learn the basics. then we get all these threads about "help, i bricked my device". just taking the little time needed to learn the basics prevent this from happening.
this is a nexus device, its meant to be able to root the device easily. this is the basic procedure.. fastboot oem unlock, fastboot flash a custom recovery, flash the su binaries or custom rom in your custom recovery, reboot. that is it. it takes me 3 minutes to do this. add on a little reading beforehand, and maybe itll take you 30 minutes. much better than getting lost after using the root toolkit, or even messing up your device messing with stuff that you shouldnt. and, occasionally, the root toolkit itself can mess things up.
btw, op, you can always install an official "ota" manually, without receiving it ota, and without having root too. also, if you flash a rooted stock rom(unmodified, only root), youll still receive otas

You can unlock and root without install a custom recovery. IF you don't install any custom recovery and leave the stock one you'll continue to receive the ota updates.
Bye

Help please. NEW to 2013 N7

Hello all. I am new to the N7. I look forward to trying out some of the awesome development in this forum. Before I begin I need to ask some things. I have spent ALL DAY today reading forums and researching this device b4 I begin. But to be honest, I can not spend days reading every post out there and still be a dad here. So I am trying to stream line this some. I am not a newbie in rooting / roming. Sorry if I have not seen a topic like this b4 posting. There are just so many in this forum now to go through. I will delete this one once helped if nessary. Also THANK YOU VERY MUCH in advance for any help I get here.
1. I have a Verizon note 2, Verizon PERMANENTLY locked the bootloaders on their phones so development has stoped/ slowed drastically. I know the N7 has a locked bootloader that can be unlocked. Is this still true on a stock 5.1.1 lollipop version? or Is there a step to reflash to an older rom I should do first?
2. I see the wugs toolkit out there and a nexus toolkit. Is there any reason to use one over the other? Are either of these working on my STOCK 5.1.1 rom still?
3. Can someone please run down the steps to achieve UNLOCK, ROOT, AND CUSTOM RECOVERY? I seen how wugs does all that in it's program. So if that is the way than a good link to use Please.
Once again. Thanks in advance for your help here. Please also feel free to add in here anything I need to be aware of b4 I begin making my N7 a beast of a tablet. I can not wait to try out some of the awesome roms and mods I have seen so far.

To root or not to root? That is the question.

1. It's unlockable
2. No need for a toolkit just use fastboot, unless you don't want to know what you're doing. It's in the platform-tools folder of the android sdk. There are many guides on xda about how to use it. Don't forget to install googles usb driver.
3. Very easy. Boot the tablet to the bootloader by holding volume down and power while turned off.
Plug into the computer and open a command prompt in whatever folder you have fastboot and type fastboot oem unlock and hit enter. Follow the steps on the tablet.
For recovery download the recovery .img you want and put it in the fastboot folder. Type fastboot flash recovery whatevername.img
To root just download the su zip from here and flash it through recovery.

You need to be careful you don't have a new Nexus 7 version which doesn't allow the mounting of any of the partitions in a custom recovery. I have one of these new Nexus 7s and no matter what I do I can't get the recovery to work, there's a thread about it.

Here's the thread on the issue. I bought my N7 yesterday and I'm affected by this. I can't resolve it and am stuck on stock at the moment which is annoying as I bought it to mess about with Roms and kernels. I'm not sure how you identify which tablets are affected but it seems the later manufactured ones are.
