Introduction
The purpose of this guide is to provide you with step-by-step instructions on how to unlock the bootloader on your Nvidia Shield.
Why Would I want to Unlock my Bootloader?
Unlocking your bootloader allows you to modify all aspects of your device to suite your needs which includes but is not limited to, installing custom Recovery images such as Clockworkmod Recovery or Team Win Recovery Project, installing custom ROM's, custom Kernels, as well as other MOD's and patches.
Will Unlocking my Bootloader Void my Warranty?
Warning: Unlocking your Nvidia Shield's bootloader will void the warranty, please note that even if you re-lock the bootloader the bootloader still show a flag that the device is voided for warranty.
This warning being given please also see this post by JordanKeyes regarding warranty information as it relates to hardware issues or hardware failures.
Unlocking your Bootloader
1. Backup everything on your device that you don't want to loose such any apps (And there respective data), pictures, videos, music, etc. as unlocking your devices bootloader will erase all data on the device. You can fully backup your devices contents without root using ADB's backup command or by using the Holo Backup Tool.
2. Download and install the ADB and Fastboot drivers for your Shield, the drivers can be downloaded here. You can also follow along with wwjoshdew's excellent video tutorial on how to properly install the ADB and Fastboot drivers for your Shield on Windows.
3. Make sure you have ADB and Fastboot setup and installed on your computer. If you haven't already setup and installed ADB and Fastboot a simple ADB and Fastboot installer can be downloaded from here.
4. Fully power off your Shield by long pressing on the Power button until the power menu appears, then select the "Power off" option.
5. Boot your Shield into Fastboot mode using one of the following ways:
5. A. Power on your Shield while simultaneously holding the Power button + Back button + Home button. Release the buttons once the Fastboot bootloader screen appears.
5. B. Run the following ADB command from a command prompt window (USB cable must already be connected from your Shield to your Computer):
Code:
adb reboot bootloader
6.Now that you are at the Fastboot bootloader screen, connect your Shield to your computer using your USB cable. Make sure that your USB cable is plugged into a USB 2.0 port directly connected to your motherboard as sometimes USB 3.0 ports can cause problems and front panel USB connections can be unreliable.
7. Open up a command prompt window (cmd) in the directory where installed ADB and Fastboot to. For example if I installed ADB and Fastboot to a folder on my Desktop which is on my D: drive I would open a command window in "D:\Desktop\Fastboot_ADB".
8. From the command prompt windows enter the following command:
Code:
fastboot devices
If you device is detected and it shows your devices serial number you are ready to move on to the next step. If no device is shown make sure you have the correctly installed the ADB and Fastboot drivers from step number 2.
9. Now that your device is detected by Fastboot the following command is used to unlock your bootloader:
Code:
fastboot oem unlock
10. You will now be presented with the bootloader unlock menu. After reading the disclaimer, use the Back button and the Home button to navigate to the "Unlock" option. Once the "Unlock" option has been highlighted use the Shield button to confirm your selection of unlocking your bootloader. It's important to remember that unlocking the bootloader will wipe all your data from the device, and that a flag showing your warranty is void will appear at the bootloader screen.
11. Once your bootloader has finished being unlocked, you will be taken back to the fastboot bootloader screen. From here you can power off your Shield.
Re-locking your Bootloader
To re-lock your bootloader you can following steps 4-8 of the procedure listed above and when you come to step 9 run the following command instead of "fastboot oem unlock":
Code:
fastboot oem lock
The above command will re-lock your Shield's bootloader. Note: As previously mentioned re-locking your Shield's bootloader will not restore your warranty or remove the warranty void flag on your device's bootloader.
Conclusion
Now that you have successfully unlocked the bootloader on your Nvidia Shield you are free to flash custom Recoveries, ROM's, Kernel's, MOD's etc. enjoy :good:.
If you are stuck with the bootloader unlocking procedure I would recommend checking out this great video tutorial by wwjoshdew.
I'm having an issue unlocking the bootloader. I have the drivers and fastboot install successfully as well as adb and fastboot. I run the command "adb reboot bootloader" which reboots my shield into bootloader but when I run "fastboot devices" nothing shows up. USB debugging is enabled.
When the device is booted normally the command "adb devices" picks up the device. It is only in fastboot that adb commands aren't recognized.
I added a picture, any thoughts?
Edit: followed the instructions in the following video and all is dandy now. http://www.youtube.com/watch?v=XSisjVwcPbE&hd=1

Look in device manager and check if the PC recognizes the shield as an adb device when in fastboot.
For me i have to switch between using fastboot and being able to copy files to it.

Hi i am having issue with dab and fast boot drivers.
When I install the driver as adb I can't fast boot to install the thor.img but once it reboots It reverts or reinstalls a shield driver and causes confusion and blocks when I want to mount.

Nvidia just released a new set of USB drivers in their Tegra for Android Development Pack which you can download from here. I would recommend installing the development pack and the drivers it includes.
ok
I have done it and these are the new drivers I have under device manager.
Still can't mount though, operation not permitted Usb debugging enabled.
here are the two new drivers which let me get as far as the mount command but no further

From that pic you posted the mount command failed because you were not root.

I have updated the original post in my manual rooting procedure thread that includes a new insecure boot.img that has a patched adbd binary to allow the insecure boot.img to provide a root shell when booted from.

Oh what I meant chevyowner was since you had responded to that guy's post about him not having a root shell after booting the insecure boot.img I decided to jump in and mention I had updated the original post to include a new updated insecure boot.img that should fix his root shell problem. Sorry for any confusion I caused there buddy!

I had to change to oil in my car in a parking lot earlier because it was cheaper to change it then it would have been add 3-4 quarts and change it when I got home. My car need 5 quarts of oil. I was not in a a good mood then.

I tried another proggie to root and got jammed up.. following the videos josh did had me rooted in minutes. Great job and thanks!
why?
Code:
C:\Users\Thomas>fastboot oem unlock
...
FAILED (command write failed (Unknown error))
finished. total time: 0.582s
I tried it with the Shield RAM tool, but won't work either..
so, i managed to root and install custom recovery without touching the bootloader. the status still reads as locked, but i am free to mod and install custom roms and such. i used towelroot apk. and flashify to flash the recovery image.

BTW, bootloader mode on the tablet:
- Hold "Volume Down" -> Press "Power" and continue to hold "Volume Down" until device boots into bootloader mode.
There is no home or back button to press while the device is off.
Sorry for bump this thread, but i have to.
I want to unlock my bootloader to revert back into KK and then try to do a clean installation of LP. Reading this guide and watching the videos, and also looking into the img downloaded from nvidia, it says i have to install the fastboot drivers. The problem is that i have already installed fastboot and adb drivers since i have some other devices as a Xperia and stuff. For me, there is no Yellow sign as shown in the video, my device is recognized as Portable Device and it already says "Shield Tablet" MTP.
I've tried going into bootloader to see if it prompts any new devices but i got nothing. adb devices show my device, but i'm not sure if i need more.
It seems that unlocking the BootLoader on the WileyFox Swift2+ is even easier.
To unlock the boot loader (WARNING!!! This wipes your user data!!!)
Go To 'Settings - About Phone' Tap 'Build Number' seven times to enable 'Developer Options'.
Go To 'Developer Options' Enable 'Advanced Reboot', Enable 'OEM Unlocking'
...## not sure if these next few steps are even needed!!
Connect to computer running "Minimal ADB and Fastboot"
Open command window as administrator (To prevent Win10 messing around).
Enter command "fastboot oem unlock"
...##
Press the phone 'Power Off - Reboot - FastBoot'
PC detects device and states "Follow instructions on device screen"
Phone screen issues dire warnings about unlocking Bootloader.
Proceed and job done Bootloader is Unlocked (device at this point not rooted).
The stock Swift2+ Cyanogen Rom is no longer available - seek out the LineageOS rom instead
I unlocked my bootloader the other day and those are the same steps I did so I can confirm this works.
I then proceeded to root the phone with SuperSU 2.78. Worked a treat.

Yes initially the only version of SuperSU I could find was v2.46, which kept failing.
Any help? My reboot menu doesn't have a fastboot option. Yes I have advanced reboot and oem unlocking enabled.
Edit: Sorted it. Turns out you have to reboot into the bootloader.

Is it too hard to google your question?
Works on most devices:
1) Turn off device
2) Hold VOLUME UP button
3) Connect device to PC via usb-cable
I installed SuperSU, before that I installed TWRP. Now I am unable to install the latest update "cm-marmite-a1478a0ee9-to-7aa1c797975e-signed"
When I download this update and perform the actual install, it gives an error. Restarting the phone via TWRP recovery gives the same error. I am getting "Error 7"
So no I want to revert back, to get rid off SuperSU and TWRP to install all updates and then later root the device with TWRP and SuperSU. How do I get the original state of the phone back?
Or do you have any advice how to get the latest update installed?
Thx.

edit: Updating to the latest Oreo update (8.1 I think)
---------- Post added at 08:34 AM ---------- Previous post was at 08:14 AM ----------
ohhhhhhh, I had to turn the phone off while connected, already running "adb & fastboot" (not just adb) then (phone connected in USB debugging mode) turn off the phone and hold volume up (no need to hole the power key as connected and I got the option to unlock with a warning that I may void the warranty. Then my phone encrypted/re-encrypted itself (I think it was already encrypted).
Now to flash TWRP (3.2 I think) and flash a custom ROM (Lineage 15.1 / 8.1 Oreo) Not sure if I should root or not. And if I do, should I root before installing 8.1?
got damit i never understand how to flash twrp i followed what google said.
fastboot flash recovery XXX.img it does its thing i reboot still no recovery im on stock cm12 ? i think or cm13 android 6.0)

your device isn't picked up by fastboot ...first of all install the very latest version of adb ...using the usual Ubuntu story
sudo apt-get install adb
sudo apt-get upgrade
sudo apt-get update
sudo reboot
then switch on your device
go to /settings/about/buildnumber
click until developer settings are enabled
go to developer settings
toggle oem unlock to on
toggle adb to on
WITHOUT SWITCHING OFF
connect device to pc/laptop with original orange wileyfox cable
now your Ubuntu machine
must install drivers and Mount the phone so it should appear as a mounted volume on desktop
now open a terminal
now run the following :
sudo adb
sudo adb devices
now look on your phone and pull down the notification shadse ..make sure you have adb connected and file transfer mode ..if not change from charge to file transfer ...
there should be a pop up window on phone screen asking for permission for adb ..select allways allow and give pernission / authorization ..
now in terminal run adb devices and it should return some value as connected device
run:
adb reboot bootloader
phone will reboot to bootloader
run:
fastboot oem unlock
*use volume up to select yes
**beware will erase DATA ...
***if it doesn't work and adb and fastboot doesn't detect your device it is a driver problem but i haven't used Ubuntu in ages so can't remember steps to update your drivers other than updating the whole adb package
****some ubuntu instructions might be a little off as I've explained previously it's been a while
*****your waiting for device means
-adb service didn't start
+try "sudo adb"
-adb drivers out of date
+try sudo apt-get update
-adb on device not toggled to on
+toggle adb in dev settings
*adb authorization not given **should still see unauthorized device
-bad usb cable
+try another usb cable
-bad usb port
+try a different usb port
_____for clarity double check Ubuntu adb instructions and commands but this should put you on the right track____

don't reboot immediately ..stock recovery will be flashed back over twrp
*i assume you know how to get to fastboot
adb reboot bootloader
fastboot oem unlock
*volume up for yes
fastboot flash recovery recovery.img
*make sure you have a copy of twrp called recovery.img in adb folder
when it says sending...
then is says writing ...
then it says done
DON'T REBOOT
UNPLUG USB
***MANUALLY BOOT TO BOOTLOADER USING VOLUME UP AND POWER
**** IN BOOTLOADER SELECT "RECOVERY"
you should then just wait on wileyfox first time it takes a minute or two don't know why then
it should boot to twrp
***you can take stock boot.img and patch it with magisk
-use: fastboot flash boot boot.img
-then you will have magisk and rooted
-using twrp apk or something like root rasher or flasher ..give apk root permission
-download twrp ..flash with apk from inside system ..after flashing select yes to reboot directly to recovery
Thanks very much, I've unlocked my bootloader now! Onto the TWRP, Magisk and LineageOS business now

okay no problem
*i know everybody likes lineage and its usually more stable and the base for many custom roms
however just my 2cents worth ...i tried all the roms for our device ..but the by far the best for me was following the tutorial on how to make our device treble compatible ..
Then ...after 3-4 months of trying different treble GSI's i have stopped on Viper Official Pie 64bit A-only treble system.img ... at least give it a try after trying out lineageOs ..
you might thank me .
I can't get my device to show up usb debugging is on, Advanced Reboot', 'OEM Unlocking' etc. I've been trying for hours and hours. It shows up to transfer files if I want that mode so my PC is recognising it, but it doesn't seem to have drivers for adb. I've tried installing google usb drivers and also this: https://afterthoughtsoftware.com/posts/using-adb-with-wileyfox-swift
sorry if I haven't explained clearly, I'm just so sleepy from going around in circles. :|
I've rooted phones before and never had this issue. please can anybody help?
edit: have fixed I think! did two things at once so not sure which. I revoked usb devices so that my computer would have to ask permission again to connect (or something like this) and also clicked a thing on my PC to allow it to update what I think said driver icons automatically, which I wouldn't have thought would help, but it seemed to find the adb driver this time. I'd probably make more sense if it weren't 1am. :|
When i got my Swift 2 X, it came updated with 8.1 Oreo out of the box and the issue I had was unlocking the bootloader.
Sure fastboot oem unlock unlocked so I could flash recovery and roms but whenever I tried flashing a bootloader via fastboot, it gave me "FAILED (remote: Critical partition flashing is not allowed)". So that part was still locked.
This I fixed way back after searching around on my own about it but since the solution to this aint mentioned around here and I can't be the only one who have encountered this I think, I am just gonna add it in here.
There are now other commands to unlock your device, fastboot flashing unlock that does the exact same thing that fastboot oem unlock does and fastboot flashing unlock_critical is the command that unlocks the bootloader.
Both commands prompts you with the usual to confirm unlock and wipes your data.
It doesn't matter if you already unlocked the device with the oem command or flashing command, fastboot flashing unlock_critical should be able to unlock the bootloader either way.
My swift was also at 8.1 I had no problem unlocking the bootloader.

Doesn't seem that many who have this lock on their bootloaders, the only ones I could find here who had locked bootloaders the same way as I had are in the LineageOS 14.1 thread.
So at least I am not alone with that but sure makes me wonder how it is so for some while others not.

I have an A2017U, Android 7.1.1, build B35, on MiFavor 4.2 and was looking to upgrade to 5.2/Oreo. I get stuck because I can't boot into EDL mode. I have not unlocked the phone but do have developer options & USB debugging enabled. If I boot with vol up + vol down + power, nothing happens even if I wait 120 seconds. I get a slowly flashing red dot. ADB works fine -- my device is recognized -- and "adb reboot EDL" reboots the phone, but not into EDL mode, just into standard mode. MiFlash doesn't see the phone.
I'm clearly doing something wrong but I'm at a loss what, given how simple the instructions are.

Try "adb reboot edl" from a booted phone.
EDL actually IS a black screen, usually without an LED though it might be red. Open Device manager and check under "unrecognized devices", or under "Ports (COM & LPT)". Should be there. If it is under Ports and it is callee Qualcomm HS-USB QDLoader 9008 then MiFlash should work
What are you planning to do? EDL back to B19 then unlock? Just curious

I plan to update to Oreo/MiFavor 5.2.
How do I issue the command from a phone? I know how to use ADB from a PC but not from a phone. That is what I have done -- enable developer options, connect the phone, verify that it is connected (adb devices) and then issue the command (adb reboot EDL).
Use the Edl tool by Djkuz
Install it to PC or laptop with all updated drivers
Open edl tool with run as admin
Boot your phone into ftm
Turn your phone off
Press and hold vol dn + power till you see ftm screen
Plug in your phone
Follow the on screen till it detects your phone
Select unlock then edl fix

Yes, but what are you going to do BEFORE updating to MF5.2?
you can't edl mifavor 5.2 because you will break stuff, besides you need an unlocked bootloader or you'll DFU brick your phone and you'll have to throw it in the trash.
I meant to issue adb reboot edl from your pc but with your phone on
On a side note, I recommend not using EDL Tool or axon7toolkit to unlock your phone. EDL Tool has a much better track record than other apps but it still has margin for error. The best way to unlock an A2017U is get a B19 EDL package and install it with MiFlash, then enter Fastboot and do "fastboot oem unlock".
Worked!

Ive used all of the Axon 7 tools as well as adb commands and all work well in there own ways.
Script errors or command errors can be an issue as well as some software (ROMs, recovery and boot imgs) a few times I've had to edit a zip or img to make it work.
After a few boot loops on my HTC.

only for Chinese (A2017) phones. It's 8.0 mifavor with the new mf5.0 interface (way more Chinese-looking). If you want to install it on a G or U you'll have to use one of the packages made for them (Usually for an update from other model to work you need to change its modem file to the one that your model uses, i.e. swap the chinese modem with the G's).
Hello, I would like to unlock bootloader on my nokia 6 (2017) TA-1033 Android Pie 9.0
First of all, I tested the official unlock but, the application tells me that my device is not supported...
I'm looking on the forum but I can't find a method for unlock bootlaoder and install twrp (then magisk for the root if supported)
Thank you very much for your help !

Not far away, a planet nearby...
After some research, apparently, there is no longer any free way to unlock the bootloader....
So I went to the cash register hoping it would be reliable XD.
For information, I still contacted nokia support

Bootloader of my successfully unlocked Nokia 6.0 !
I just had a driver problem on my computer.
If you are in the same case, my problem has been solved by installing "OST tool" :

run the "launcher.exe" and restart computer
Thanks Techmesto for the key.

sorry for taking so long in getting bk to u i decided to get rid of this device and got a pixel 3 xl thanks.
stupid Nokia, why bother rooting this with a pay service!
and a bunch of instruction, waste of time!
I own a xiaomi 9 se for unlocking BL just take a week, oneplus 6 just need a second!
I'm not saying anything about techmesto, but I do not know them. Man, do you know the damage someone can do with an IMEI and S/N? Damn Nokia.

Thanks for the super indepth guide! I've been waiting for years now for HMD to release the bootloader unlock tool for the OG phones, but that's clearly never gonna happen. Techmesto charges 8 dollars for the key and the downgrade + unlock, but 5 dollars for just the key. So I think I'll follow your guide to downgrade and then purchase the key from them afterwards.
I have a brand new Oneplus 8 Pro from China with global ROM installed.
I wanted to unlock the bootloader however there is no fastboot option in the boot menu.
There is Start, Restart Bootloader, Recovery and Turn Off.
The Fastboot option is missing.
I can connect the phone to my PC, adb recognizes the phone, but Fastboot is missing.
Any ideas?

Sure. You are allready in that mode. Just type fastboot devices and check..
I did that but no response.
The cursor jumps to the next line but there is no response from the phone.
If I type adb devices the phone is listed but the fastboot command doesn't return anything.

Restart to bootloader, then fastboot should work. If your phone is still on, and you can access adb, you should also be able to type adb reboot bootloader
Thanks.
So apparently the command "fastboot devices" returns nothing.
However I was able to unlock the bootloader just by entering "adb reboot bootloader" then
"fastboot oem unlock".
What confused me was that there is no "fastboot" option on the phone itself as there was on my Oneplus 5t.

The option in the power menu is called bootloader (fastboot only will work there) the hint was in the adb command I gave you, adb reboot BOOTLOADER. Not sure why they changed what the menu was called but I'm glad you got it sorted. To give you a short summary, adb will only work when your phone is powered on and booted into android, or if you have recovery mode open and on the adb section, and fastboot only works in the bootloader hope that could help!
Edit: fastboot devices should work but only in bootloader mode, not when your phone is started normally

You have to insert a SIM card, boot of the device and make a phone call to get it to register your device. Wait a few minutes and then restart your phone. Go into settings under about phone and enable developer options. Back out and go into developer options and you will see OEM unlock. You need to turn that on and USB debugging. Both of them must be turned on. Now you can boot into fastboot and unlock your bootloader. It will wipe the device so if you have any data you want to save you better do it now.
hey i am having this issue, i am able to adb reboot bootloader but when i try to oem unlock or anything else, it is just waiting for device and not finding it....

That's a driver issue.
Are you using Windows 7? If so use 10
If not then sort out your driver's and it'll be fine.
Theres a bug in 7 where the driver for ADB cannot be collaborated with fastboot drivers.

thanks for the reply, i am on windows 10 and i dont know what is causing the issue when the phone goes in fastboot, but i went on my wife's laptop and got it working within a few minutes after installing adb...
Having similar problem here:
win10x64, drivers installed, USB debugging is enabled.
ADB sees the devices, reboots it correctly with "adb reboot bootloader"
then bootloader menu's shown:
START // RESTART BOOTLOADER // RECOVERY MODE // SHOW BARCODE // POWER OFF
Fastboot mode
Product_name - kona
Variant - SM8 UFS
BOOTLOADER VERSION - (nothing appears here)
BASEBAND VERSION - (nothing appears here)
Serial number - (appears 8-symbol sn)
SECURE BOOT - YES
DEVICE STATE - LOCKED
trying to communicate with smartphone via terminal "fastboot" command doesn't do much:"fastboot devices" doesn't return anything at all, "fastboot oem unlock" just shows <waiting for device>
tried to reinstall drivers

If you type fastboot reboot what happens? If nothing then either you're device doesn't have usb debugging on, could be the cable/usb slot (some people have had issues with this)
Or its the driver installed for fastboot.
Show hidden devices in device manager you may have multiple devices, remove them all and start over.
Your also need to have used ADB and have trusted the device (prompt will appear on your phone the first time you connect it successfully whilst in your phones system, not fastboot)
for windows 10:
firstly download the google adb driver:
Get the Google USB Driver | Android Studio | Android Developers
The Google USB Driver is required to perform adb debugging on Windows with Google devices.
developer.android.com
then do the following:
1. adb devices [you should see your device ] > adb reboot bootloader
2. device manager > update driver > chose from list [android device]
3. still in device manager got the newly populated Android device and then update driver > choose adb interface
3. fastboot oem unlock
etc.
hope this helps

Secure Boot means your Bootloader is locked.
Setup fastboot correctly, open a cmd window, navigate to fastboot.exe and enter fastboot oem unlock, follow instructions on phone screen
