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.
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.
So I upgraded to Nougat on my P9 Lite, unlocked boot loader, used twrp, flashed roms and everything went smooth. Saw a more up-to-date version with no bugs, so I had to downgrade to MM first.
I followed a guide, but I messed up somewhere and ended up having my bootloader locked, and I can't access the OS to enable developer options and oem unlock from settings. The reason why I can't access the OS is that I am stuck in the setup. I am stuck at the part where I have to sign in to my google account. It doesn't show a keyboard, only a microphone, and I can't use that for my password (it won't let me).
Any ideas?
TL;DR messed up during downgrading from Nougat to MM, now TWLR is gone, bootloader is locked and my main issue is that when I get to the google account sign in part during OS setup, there is no keyboard (I can only use dictation) so I can't sign in... So I'm stuck
Also, can I unlock bootloader without access to OS, without being able to navigate to settings, enable developer options and then oem unlock?
1. Stuck in OS setup? Signing in to Google? Hey, it's not obligatory, can't you just skip it?
2. Flashing ROMS locked your bootloader, it's normal, but I'm sure it didn't change the "oem unlock" setting you had surely enabled before. Go to fastboot mode and check Bootloader and FRP status on the bottom of the screen. If FRP is unlocked, you will be able to unlock bootloader again.
3. If you have your TWRP gone (flashed by stock ROM), flash the recovery partition manually - fastboot flash recovery TWRP.img (download from Meticulus Project site).

It is obligatory, I couldn't skip it. I tried to use other methods of signing in, but then it asked me to reset password at the end.
Both Phone and FRP are locked
I think I have missed this, but I can't do it via fastboot because I keep getting "Command not allowed" whenever I try to unlock bootloader or do anything via fast boot.
Also, thank you so much for your time and input. It is much appreciated.
That's weird, I flashed my phone several times with different ROMS (not Nougat) and this setting (oem unlock / FRP unlocked) stayed enabled. Don't know where it sits then and how to change it without getting inside OS. But - what about TWRP? Oh right, you won't be able to flash it without unlocked bootloader... Oh, crap. I would try SRK Tool for Huawei to play with bootloader, it uses fastboot so shouldn't help, but maybe, just maybe? Maybe try flashing whole ROMs through dload folder on SD? Stock 120, 161, Nougat, I would try these. I hope there is some way to unlock FRP, probably it's possible in DC-unlocker (it's a paid software).

Yes, it's very weird. I haven't done the process a lot. But I've flashed a couple of phones I had before, went smooth. Nothing major like this happened before.
I will consider the SRK Tool and I did not know about the DC-Unlocker tool, thank you for telling me about it.
Flashing whole roms through dload folder only works with Nougat for some reason, and I keep getting stuck in the signing in problem because of no keyboard, someone told me that's incomplete software, I'm hoping that's the case, any ideas where can I get it from?
Again thank you Jagiel88 for your time and advice xD
No problem, unfortunately I haven't tried Nougat yet, so search for help on down/upgrade Nougat beta <-> Marshmallow threads .

Hi, have you found how to solve this? I can't access recovery because I messed up, cant flash recovery because bootloader locked. Cant unlock bootloader because says command not allowed... I did 3 times so the code is working... Any clue?

Can't access to any OS. I definetly know i had OEM unlocked, then after unlocking via fastboot, I wasn't able anymore to access the system.

Unlock bootloader, after that you able to flash rom.
You use this command?
fastboot oem unlock YOUR_OEM_CODE
If you tip:
fastboot devices
What's you see?
Hi everyone,
my v20 h990ds ( stock without root ) is in bootloop.
When i tried the "DirtySanta" solution, i can do the steps on my device ( bootloop ). So i decide to unlock the bootloader.
I come from the nexus community, so i have searched for a solution by fastboot.
Now then i try to ask to the LG from my "unlock.bin" file, it says that my phone is not unlockable (wtf?).
Searching in to the forum, i read about the "download mode", but when i try to jump in, my phone reboot itself after 4 seconds. Is it normal?
Do you have another solution for my phone?

are you following the directions here > https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296
The dirtysanta hack is the unlocked bootloader, it installs the Eng Aboot specifically for devices that cant be unlocked.

yes you'll have to get your phone booting up to root it

Hello, i am new here. I wanna know if it's possible do root to the Moto G4 without PC. Thanks!
You have to unclock the bootloader first to make any nasty changes in the device. If you have an unlocked bootloader & custom recovery installed then you don't need a pc for that purpose. But if your phone is in factory condtion, then you must need a pc. That's the general method most of us use.
It's too easy and you can do this in 15 minutes if you have the unlock code, drivers & fastboot installed on pc and twrp image file ready.
