After youve unlocked it to root. So you still lose your data the first time you unlock it.

In thread in my country , I saw tut for unlock boot loader without lose data in first time In nexus 10 I think in nexus 7 2013 work too but I did not test it yet.
the method is
1. Put recovery image to sdcard.
2. Download
http://download.chainfire.eu/372/SuperSU/UPDATE-SuperSU-v1.86.zip
Save to sdcard
3. Boot to bootloader and use command
fastboot boot recovery.img
4. Install zip file for root
5. Reboot
6. Install BootUnlocker and Open
You can unlockboot loader without lose data

Which recovery image should be used for that? Standard recovery, CWM, TWRP?

CWM or TWRP can use

yep, I installed it too...
however one important thing you should not forget (copy/past from a review) :
"Works great but be careful Once you have unlocked and rooted your phone this app works great to lock the bootloader again. But use caution when updating OTA. I allowed an OTA update to Android 4.4.2 while locked and I lost root access (expected) but because I didn't unlock before the update, I am now locked without a way to unlock unless I wipe the phone. Great app. Just make sure you know what it does and how to use it."
--> unlock before to apply an OTA

does flashing stock rom remove root or re-lock bootloader?

as topic states....i want to flash store rom to make sure everything is deleted since settings factory reset did not do so. however, i want the bootloader to stay unlock and phone to retain root. thanks in advance!:victory:
Boot loader will stay unlocked, root will be deleted if you're wiping /system.

There is an app that will save your root.. It is voodoo something.. Will find it and tell you..

If you flash factory image via fast boot you will lose root and custom kernel. Boot loader will stay open until you lock it again using toolkit or from factory image command via fast boot.

don't use toolkit. the command to relock bootloader is,
fastboot oem lock

Don't bother locking your bootloader. You'll just have to wipe everything the next time you go to root the phone or flash anything

Pay attention. He was responding to the post he quoted and telling that member the proper way to lock a bootloader.

[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.

Nexus 7 LTE factory image

when i unlock and root my device (Nexus 7 with LTE) how can i get back to unroot and lock
will be a factory image next time
You don't need an image to lock the device. If you want to go back to stock unrooted, you can fastboot boot recovery and then backup all partitions prior to rooting it after the unlock. Then you can do a regular fastboot flash to flash recovery and flash the superuser zip. Or wait for a factory image as I think one will be along eventually.

Easiest way is to:
fastboot OEM lock
fastboot OEM unlock
fastboot OEM lock
Unlocking will wipe all data, including root so you'll be stock. Then relock the bootloader.

Nope. Unlocking does not touch root. Root is in the system partition and most people with root have a custom recovery. Unlocking only does a true factory reset (wipe the data and cache partition which includes sdcard). This won't work to remove root.

It could be a couple weeks from when the device was released based on how long the WiFi version took.

Is it possible to have root without installing a custom recovery?

Hey everyone.
I want to root 4.3 but I dont want to install CWM or TWR or another custom recovery. I want to keep stock recovery so I can directly update from Google when 4.4 is released.
Is there any way I can root without having a custom recovery?
Thanks for the help.

Yes, you can root without flashing a custom recovery. The first step is to obtain root access. The next step of installing a custom recovery (i.e. CWM or TWRP) is to flash ROMs and Kernels. You can just stop at ROOT.
FYI - There are stock and very close to stock ROMs available. Once Android 4.4 is released by Goggle, it does not take long (1-2 days) before people have the 4.4 available for flashing especially for the stock or close to stock ROMs. The more customized ROMs may take a little longer to have Android 4.4 ported into their ROMs.

The command posted "fastboot boot boot.img" would boot your device once into a custom recovery without actually installing the recovery. From there, you can use the one-time booted recovery to install a root zip.
Yes.
I'm unlocked and rooted on the latest 4.3. N10 is so fast I don't feel the need for a custom rom at this present time.
N-Cry tool kit was the easiest I tried.

First you need to download the latest supersu. Then you need to download a custom recovery from here: http://download2.clockworkmod.com/recoveries/recovery-clockwork-touch-6.0.3.5-manta.img
Place it on your C: drive.
Then go to fastboot and type:
Fastboot boot recovery C:/recovery-clockwork-touch-6.0.3.5-manta.img
Then select recovery with the volume buttons and press the power button.
In recovery flash the latest supersu you downloaded.
! Wipe cache and dalvik cache !
Reboot.
You're now rooted and still have the stock recovery.

Thanks a lot!
One last doubt. When you say place the recovery img in C: you mean on my PC or on the Nexus 10?
Thanks again.
EDIT: I tried following your instructions but didnt manage to boot into the custom recovery. Maybe Im missing some step in cmd.

Doesn't that require you to unlock your bootloader first? (and therefore wipe everything from the N10)
I originally rooted my N10 (running 4.2.2) using this: http://forum.xda-developers.com/showthread.php?t=2003938 without unlocking the bootloader first...
No idea if it works on 4.3 or not, though...

I'm not sure if it requires unlocked BL. You can try, if it doesn't work, then you shall backup and unlock. But I believe it will work .

Will any of these methods work for the new Samsung Galaxy Tab 4, or are there any other ways? I want to gain root and upgrade when updates come out as well, but we have no custom recovery yet for the Tab 4. I wonder if I could fast boot with the custom recovery for Tab 3 if it will work?

Hi folks!
Where find I one SuperSU.zip file to root my device through ADB SIDELOAD (stock recovery)?
My device:
- Boot loader LOCKED;
- UNroot;
- 4.4.3 stock.
I don't wanna install a custom recovery neither unlock the boot loader.
Is it possible?
Thanks in advance.

To flash the super su zip you need a custom recovery, for that you need to unlock the bootloader. You can find it by Google "supersu zip file xda"

You can just boot into the custom recovery
fastboot boot recovery.img. You'll just boot into and not install it. Once you boot into it flash supersu. You're retain the stock recovery. You can then re-lock the bootloader if you want.
Oh, as an fyi, when you take an ota you do lose root so you may want to consider leaving the bootloader unlocked so you don't have to wipe your device again after the ota if you want to root it again
