I don't want lost my warranty and for many others reasons, i don't want unlock my bootloader. I see many people saying "you want root with a locked bootloader ? Unlock your bootloader !" To this people, i say "no". Why i would take the risk to cancel my warranty for that ? Many devices with a locked bootloader will be upgraded to lollipop. So this is my question, any chances to get root with a locked bootloader ?
Here And then go here
And in any case, it can be done, depending on what state your tablet is currently in.
I'm on Lollipop, rooted and still with a locked bootloader.
If you're already on Lollipop without a custom recovery, you may be out of luck or will just have to wait.
If you've got a custom recovery, or are still on KitKat, it can be done. See here: http://forum.xda-developers.com/showthread.php?t=2945044
Sent from my SHIELD Tablet using XDA Free mobile app
I was so ecstatic when I got the tablet, I ran the OTA to Lollipop before using towelroot.
I followed the steps using adb
The tools they provide using the root method through; pushing recovery.img from bootloader, etc. Worked well
I was really amazed how fast I upgraded, before I knew it, towelroot said "device is not supported" I about wined.
On lollipop (from immediately upgrading from Kitkat), and have root using the adb method
-to unlock bootloader (oem unlock)
-push recovery.img (provided in link)
-install the lastest SU from the recovery (CWM v6)
reboot
The steps to re-enable bootloader lock is simple
adb oem unlock
If anyone would like assistance I would be happy to help.

I just purchased a N7 yesterday, and it's supposed to arrive in a couple of days. I'm using a Mac OS computer and comfortable with ADB, so which is better: root first before updating the firmware, or update to the most recent version of firmare and then root? And which rooting method do you recommend with a Mac?
Thanks for your suggestions!

I would update first then root, and use wug's toolkit to help you through the process.

I personally have done the following steps:
- I've rooted it first;
- installed OTA RootKeeper (to keep the root after updating - the app must be configured before updating firmware);
- I've updated the firmware to the last version.
I performed all those steps using my notebook which has Windows 7 OS, so for Mac OS I cannot make any recommendation.
I hope this helps you.
Thank you both for the suggestions! Is the Wug's toolkit for Windows OS? Any such toolkit for Mac OS or Linux system? Thanks!

Good Dog. The OP said he had a Mac.
@OP
May as well do stock firmware upgrade first if it is needed.* On the rare chance that you get a device that suffers some kind of infant mortality - the device will be pure stock for the first little bit of operation (in case an RMA is needed). And the flashing operations which take place IF an OTA is needed will give flash memory a little workout.
Just bear in mind that the bootloader unlock operation will erase everything from /data (factory reset) when the "fastboot unlock" command occurs. So, if you operate the device as pure stock for a while, you will either need to backup stuff or regard your initial customizations as disposable.
fastboot methods are the most expeditious way to proceed on a Mac.
If you use TWRP 2.4.4.0 as your custom recovery, it will peek in /system to see if you are rooted and offer to root your device with SuperSU for you (just before you reboot from within TWRP).
The way I see it, the rooting procedure is 4 steps total:
(Note: use the "tilapia", not grouper recovery image if you have the 3G/LTE Nexus 7)
Code:
fastboot unlock
fastboot boot openrecovery-twrp-2.4.4.0-grouper.img
... make a pure stock Nandroid backup
... reboot TWRP and it will offer to install SuperSU for you
(optionally: fastboot flash recovery openrecovery-twrp-2.4.4.0-grouper.img )
Those 4 steps above will leave you with Pure Stock + Rooted ; even the recovery on the tablet will be pure stock until you flash it there (optional step 5 above).
It's up to you to get the Mac SDK (for fastboot & adb) installed and figure out using command lines - search for that, don't ask.
good luck
* I thought I saw a report recently that someone had JDQ39 on a device purchased less than 4 weeks after the last update - your device may not need upgrading yet.

Thanks a lot for the detailed information and the kind help, bftb0! I really appreciated it.
I had a two-year-old version of Mac SDK, and only used adb before. Just finished grabbing the most recent version. I prefer command lines instead of button pushing. Once N7 arrives, I will start to have fun with fastboot...

One more question. Is the first step (unlocking) necessary for the later steps such as root access? The reason I'm asking is that, unlike rooting, unlocking is irreversible, and would avoid the warranty.
Edit: I guess that the bootloader has to be unlocked to flash a custom recovery, right?
Unlocking is necessary to use fastboot commands and it's not irreversible as you can relock it with "fastboot oem lock" but if you want to unlock it another time it will wipe your device again. And if you flash recovery with fastboot then yes your bootloader must be unlocked but you can relock it after.

That's great! Thanks a lot for the help...
Good news everyone!
I've added the capability to unlock and lock the bootloader of the Yota Phone 2 to @segv11 's Boot Unlocker. There is already a pull request on GitHub for my code.
This means that everyone can now safely use custom recoveries without having to worry about warranty issues or losing data because of the mandatory factory reset.
Technical information
On the Yota Phone 2, the bootloader uses position `0x004FFE10` of the "aboot" partition, stored as `00` / `01` to indicate lock status, whereby `01` stands for "unlocked".
Download
For those eager to try it, until the pull request is merged, you can download the app from my GitHub repository. Please note that it is signed with my own developer key, so you will have to manually uninstall the official Google Play version from your device before installing it.
wow great just what i wanted :good::laugh:
Did you come to try it yet? I'd love to hear whether it works for other users.
For me (running android 6 beta) the app is not compatible with my device. (NOT WORKING ON DEVICE WAS THE VERSION FROM GOOGLE PLAY STORE)
I am using a yotaphone 2.
L.E.
could anyone confirm this app can relock the bootloader if root access is available? I have not yet rooted it yet.
I am asking this because we will need a locked bootloader to install google pay.
Did you try to install my version over the official Play Store version? This doesn't work, as the APK is signed with a different key. You have to uninstall the official version first.
Regarding a relock confirmation: I didn't try tools like SafetyNet, but when you relock the bootloader using Boot Unlocker, the bootloader command fastboot oem unlock again offers to unlock the device.
Unfortunately, I can't investigate much further currently, as I have installed Magisk, which needs a permanently unlocked device.
I testet the github version. The attempt to relock the bootloader on a unlocked Yotaphone2 on Android 6.0 ends in a boot loop
In my experience, the boot loop occurs when the boot partition is modified (e.g. after installing Magisk). If you flash the original boot partition (and potentially also recovery), the phone should be able to start just fine.
Different way?
Great job! Is any solution to unlock bootloader via fastboot mode like flashing modified aboot partition image? On my YD201 MM after turn off Extreme Power Saving Mode my lock pattern had been changed itself and i don't want to wipe data by fastboot oem unlock.
I have a VNS-L21 with the stock 6.0. I unlocked the bootloader, installed TWRP and rooted my phone. Since the 7.0 is coming very soon, I want to go back to stock so that when the update comes I can safely install it through OTA. I've heard people bricking their devices by updating a rooted device and I don't want that.
Try flashing stock B160 rom if that doesn't relock bootloader then download srktool (if haven't) install connect your phone to pc choose bootloader and choose relock type Y type your bootloader code in (you have one right? Its unlocked should have) type Y again and wait for the process to finish the only draw back of this method that your phone might say relocked not locked which means it was unlocked but if you turn oem of in your phone setting it should say locked (if im right) but theres methods to make your phone show locked but it might actually already show that its locked not relocked hope it helps
I've been using custom ROMs for a while on my A2017G but decided to get back to stock. Before doing all the bootloader unlocking/rooting etc I backed up my original firmware (Nougat, B09). So I reinstalled the original firmware that I had backed up but somehow lost TWRP in the process (the bootloader is still unlocked). I then used Axon 7 Toolkit to re-install TWRP. Unfortunately I cannot get to bootloader mode through Android Recovery as it reboots normally. Axon 7 toolkit gives me the following notice 'If your device rebooted normally then your device has no access to fastboot. Follow the miflash instructions for the bootloader unlock option to restore your device's fastboot mode'. The thing is the phone is bootloader unlocked so I don't need to unlock again.
Basically, I cannot install TWRP through bootloader mode. I also tried adb-fastboot tool from my Pc but same thing happens, phone reboots normally.
What I really wanted is bring back the phone to full stock, including re-locking the bootloader.
I also want to have the bootloader re-locked again before selling the phone.
Any help/ suggestions much appreciated.
Good lord, don't use the Q&A mode for a simple question. XDA Labs opens it on a browser window
Follow Controllerboy's guide, but only the part where he installs TWRP with axon7tool. After that, boot into TWRP and follow raystef66's guide on how to get rid of the 5 seconds screen. That'll give you fastboot. Then flash a full stock system, stock recovery, and you'll probably be safe enough to relock
But I'd ask the next owner if he/sge actually cared on having the bootloader unlocked. Relocking it is risky as $hit you know.
Sorry, am kind of new and was not sure which way to post my comment. Thank you for responding and the advice. I managed to install full stock, actually downgraded to Marshmallow so I can get to fastboot/bootloader mode now. Thanks again.
You can still have bootloader mode on Nougat if you follow raystef66's guide. Plus it will hide the 5 secs screen
Actually I discovered I can't get into Fastboot mode from stock marshmallow so guess it's back to nougat with raystef66's guide.
I typed the code into my keypad and it went to system settings and it said I can't bootloader unlock this phone. Apparently I need this to grant permission for root. How do I root this particular phone? I managed to get a systemless root on my galaxy s5 by using TWRP to flash Majisk, although TWRP doesn't work for this phone. How can I actually root this phone. I would prefer to root with Majisk but honestly, I'd appreciate to know any way that I can really. Much appreciated!
if the unlock bootloader ALLOWED : is NO
then sorry sir
you cannot root this device!
There is a version of TWRP recovery for this phone which you have to flash to the boot partition, but I think in order to do this you need to have your bootloader unlocked. If your service menu says this option is disabled, then you're out of luck. :/ Sorry.
1. Go to Sony Developer site. Get bootloader unlockin code for your IMEI.
2. Dowload flashtool 9.25 with drivers.
3. In Developer menu tick allow OEM unlocking and USB debug.
I did it for my. It was not allowed to unlock bootloader first, but flashtool does it (in two steps)
i unlock the bootloader ,but i cant root this phone.
i try many ways but its faild.
plz help me to root my phone
old post I know, but did you get this rooted at all? as I have the phone (5 years now) and want to get a different OS on it to de-google it - but I'm new to it all, I have flashed firmware on other devices but never ventured into mobiles
cheers
