[HOW-TO]Unlock the Bootloader on the Nvidia Shield

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

and here's it telling me no in abd and fastboot

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!

No problem.
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 made two videos on the NVIDIA Shield. Please let me know what you think @shimp208.

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.

Where did you find the towelroot apk? Been searching for over a month with no success.

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.

Sorry guys, I know this is a very old thread but I've tried this so many times and did not work. My problem is that nothing happens in my device when I type the command to unlock the bootloader using Terminal.
I get the following message: Brunos-MacBook-Pro:fastboot Brunolima$ ./fastboot-mac oem unlock
...
OKAY [ 0.001s]
finished. total time: 0.001s
Brunos-MacBook-Pro:fastboot Brunolima$
And then that's it. It doesn't reboot and when i manually reboot it is in the same state as before.
Any ideas guys?

Hey, I've been trying the same thing. Didn't have your specific issue but I think it may be related to the fact that it's already unlocked.
That said, I to make everything work I basically used this guide + the commands from the official TWRP guide at the page "TWRP for OnePlus X" + the command from a guide in the official OnePlus guide called "[GUIDE] ONYX: How to Unlock Bootloader, Install Custom Recovery, Root, Take EFS Backup & More !!" --- sorry but I can't post links.
All in all the commands I've used where:
adb reboot bootloader
fastboot devices
fastboot oem unlock
fastboot oem device-info
fastboot flash recovery twrp.img
fastboot boot twrp.img

Wiley Fox Swift2+ Bootloader Unlock

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.

---------- 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____

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.

Boot loop after Android O DP2 update

I installed Android O DP2 update via OTA yesterday. The phone updated, rebooted to the new build and restarted abruptly and since then has been stuck in a boot loop. The Google logo shows up, goes to the android animation step and then Google logo appears again.
I don't have bootloader unlocked, don't have TWRP and have done OTA updates. I am able to get into the stock recovery mode.
How do I fix this, i.e. make it work in any way without erasing the user data? I don't mind extreme steps (without erasing user data) because I was planning to reflash 7 with unlocking & rooting today.

Try to wipe cache from recovery - in recovery hold volume-down and select "Wipe cache partition". Should do the trick

I tried, didn't work. Had to factory reset in the end. Also opted out of beta

I just read that some people that took the update from certain builds had boot loops due to the update only replacing part of the OS but leaving the 7.x.x system in place causing it to boot loop. I think it was like on android authority or something like that.
Sent from my Nexus 6P using XDA-Developers Legacy app

I have similar problem. Phone became stuck at Google logo and bootloop. I didn't have OEM unlock and debugged enable when phone was working. Now I'm stuck because It cannot flash with any factory image rom. Anyone with solution, please help. Thanks

You can unlock your bootloader to flash a stock ROM. Do you need the steps?

To flash a system image:
Download the latest system image for your Nexus 6p, then unzip it to a safe directory.
https://dl.google.com/dl/android/aosp/angler-n2g47o-factory-dc258043.zip
or Download any of your choice from here
https://developers.google.com/android/images
Connect your device to your computer over USB.
Start the device in fastboot mode with one of the following methods:
adb tool
http://developer.android.com/tools/help/adb.html
Using a key combo: Turn the device off, then turn it on and immediately hold down the relevant key combination for your device.
POWER BUTTON + VOLUME DOWN BUTTON
Click to expand...
Click to collapse
If necessary, unlock the device's bootloader using one of the following methods:
Code:
fastboot flashing unlock
If you are updating an older device, run this command:
Code:
fastboot oem unlock
The target device will show you a confirmation screen. (This erases all data on the target device.)
Open a terminal and navigate to the unzipped system image directory or Open a command prompt from within your System image folder (navigate to where you have flash-all.bat located on your PC, shift + right click anywhere within that folder, select open command prompt here
Execute the flash-all script.
Code:
fastboot flash-all.bat
This script installs the necessary bootloader, baseband firmware(s), and operating system.
Once the script finishes, your device reboots. You should now lock the bootloader for security:
Start the device in fastboot mode again, as described above.
Execute:
Code:
fastboot flashing lock
or, for older devices, run:
Code:
fastboot oem lock
Locking bootloader will wipe the data on some devices. After locking the bootloader, if you want to flash the device again, you must run fastboot oem unlock again, which will wipe the data.

Thanks for your reply..But you can only do this only if you have an unlocked bootloader and debugged mode on. I didn't have either so it won't allow to flash with locked bootloader.

Exactly why i posted that. You can unlock your bootloader without turning USB debugging ON. Just Boot up with the POWER + VOLUME down Combination and use the bootloader unlock command in my previous post.

FAILED (remote: OEM unlock is not allowed)

Yes, I got the same error. Again, it's because of bootloader locked and debug is off. Any other ways to unlock or flash this phone?

To unlock you first need to have ticked the allow OEM unlock from developer menu within the OS. It won't work otherwise.

Dear Mavelos,
I already tried that and the installation was successful, but my first problem still there, when I installed the Android O Beta, the touch of my screen stop working after the 2nd day of installation.
Now I don't know if this is a problem with Android O or just a coincidence and the hardware its broken.
I went to a lot of forums but nobody its talking about that (Touch Screen not working)
Did You guys hear anything about it?

I have the same problem as others, stuck in a bootloop and had not enabled unlock in dev options. I can get to bootloader but not recovery mode (bootloops when I select this). I would love to try this OTA side load, but I can't see my device in adb. I can see it however in fastboot. Not sure how to get it up in adb....
Any help would be much appreciated.

If you get a bootloop when selecting recovery, try rebooting to recovery with fastboot
Code:
fastboot reboot recovery
if that doesn't work, then i think your device is bricked.

If your touch screen isn't working, it might be related to the Android O Beta you flashed. Can you boot the phone up? If you have an OTG cable, connect a mouse to your phone. Turn on OEM unlocking in developer options. Do a factory reset.

i have the same problem with this, and i cannot unlock it too, is there anyway to unlock this phone?

OTG works Perfect! But.....

So I Follow your suggestion and I bought the OTG adapter, works perfectly I unlocked the bootloader from the developers options, did a factory restore with a previous image, etc.... Touch still not working, I'm starting to believe this a hardware problem with the screen.... Bad Luck maybe, I don't know! ..... I will have to buy that expensive screen ($140).
Anyway thanks for the help...

[GUIDE] Root Huawei Honor 5C and install TWRP custom recovery (EMUI 5.X)

Did not find any post mentioning rooting for 5C on EMUI. If there are any, let me know and I will take down this thread.
Note-
Applicable for Windows 7, Windows 8 and Windows 10
Similar steps are applicable for EMUI 4.X as well but TWRP file will change.
Saw many user on Honor 5C FB page and on XDA struggling to get root working on EMUI 5. most of the cases I saw, were for EMUI 5.X. I followed the steps mentioned or as applicable for any devices and I did not face any issue so though of compiling this guide for new users who may have faced issue or not able to root the phone. (may be mainly because of correct and working TWRP issue) . I will just simplify the steps so that any new users can do this without any problem and without any prior experience to rooting, it may be long but will be the simple enough for all the users.
Prerequisites-
Enable the developer option in settings-
Go to Settings--> About Phone-->Tab build number 7 times to enable this setting.
Go back in setting page, just above system update, you will see a new menu as -Developer Options
Scroll for the debugging section and enable the USB Debugging
You will be prompted for the confirmation with RSA key, just accept it.
Enable OEM Unlock in Developer Options (just above the USB debugging option) – Most probably this option will not be there on EMUI 5.0 (only few have seen on EMUI but it was there on EMUI 4.1 for all but rarely on EMUI 5.0 or may be because I have used dload most of the time which grayed out this)
Installation of required Drivers.
Connect your phone to PC and install Hi Suite on PC and it will additionally install all the necessary drivers to PC and HiSUite on Mobile.
Download and Install ADB from Link
Accept all the prompts and install ADB drive system wise.
Once installation is completed, if default options are chosen, it will be under C:\adb
Downloading the necessary files.
Download TWRP from Link Thanks to @OldDroid for his Original Thread . Rest of the contributor and credit in original thread by OldDroid.
Move the downloaded file under C:\adb or wherever you have installed the ADB.
Download the SuperSU file from this Link and put it in SD card or keep handy on PC so that you can copy to internal memory later.
Get the unlock as mentioned in this thread
Actual Procedure
Unlocking the bootloader-
Backup all your data as unlocking the bootloader will reset the device and all your data will be erased.
On windows machine, go to folder C:\adb or wherever you installed the adb drivers.
Press shift+right click together and select Open command prompt here
Run - adb reboot bootloader (this command may prompt for acceptance of RSA key if not already accepted)
This will boot the phone into bootloader mode.
Run - fastboot oem unlock <16 digit unlock code- Put your actual code you obtained from Huawei site > (This step will unlock the bootloader and will erase all your data)
Phone will restart automatically.
Installing TWRP
Once on the system, open the PowerShell or command prompt again in ADB folder (can use the previous instance as well)
Run - adb reboot bootloader
Once in bootloader, Run - fastboot flash recovery twrp-3.1.1-0-venus.img (This will install the TWRP recovery for EMUI 5.0 on your phone)
Once done with the flashing the TWRP, Run - fastboot reboot
Rooting
Once booted to system, open the PowerShell or command prompt in ADB folder (can use the previous instance as well)
Run - adb reboot recovery
And your phone will boot into the TWRP recovery.
Copy the SuperU file downloaded to SD card or Internal memory.
Install the SuperSU zip.
Reboot and enjoy.
Happy Flashing.

Hello,
I had the NEM-L51 from my mother running EMUI 4.0x, and decided to upgrade it to the latest version.
It was unlocked, with TWRP as recovery, and rooted.
I did flash back the stock recovery (from HuaweiUpdateExtractor/Update.app), rebooted the device, and applied the OTA (B350 first, then latest B357).
Until then everything is fine, but when I try to flash the TWRP recovery, it doesn't work :

Neither the recommended Venus one, or the current / previous nemo one can be flashed.
Phone and FRP status in fastboot mode both shows Unlocked / Unlock, and the OEM Unlock option in EMUI Developper Settings is also enabled (I toggled it just to be sure).
I'm not sure what's wrong.
Would the update mess with the OEM unlock (by relocking and showing a wrong status) ?
I'd rather not try fastboot OEM unlock with the code (still have it somewhere) and lose data.
Thanks for any advice

So it's not a recovery issue.
How useful is the HiSuite backup ?
If I make a backup with it, will it be able to restore most user app's and system's data ?
I'd rather not re set everything up, and I'm afraid I'll have to retry to OEM unlock the device (so force wipe), even if it says it's unlocked (which it should have remained in the first place)

If I make a backup with it, will it be able to restore most user app's and system's data ?
I'd rather not re set everything up, and I'm afraid I'll have to retry to OEM unlock the device (so force wipe), even if it says it's unlocked (which it should have remained in the first place)

Hisuite can be used for back.. reliable one but not same as titanium backup. Backup WhatsApp on local and g drive. Zip the WhatsApp folder in internal memory and then copy to pc.
Rest other apps, via hisuite (can backup WhatsApp as well here).

Before trying that recovery, I just tried to flash the stock one from NEM-L51C432B357 full OTA package, and it doesn't work either

You file should be in path D:\Android\platform-tools\ and not D:\Android\HuaweiUpdateExtractor_0.9.9.5\
I hope adb is installed under D:\Android\platform-tools\, if not, it will be udner C drive as C:\adb\
copy the recovery file whereever the adb is installed and then run the command
fastboot flash recovery twrp-3.1.1-0-venus.img (replace name with your actual file name)

Ok, so in fact fastboot OEM unlock status was not accurate, and something I didn't notice was the absence of dm-verity warning when booting (showing when it's actually unlocked)

May be. try moving the files and then flashing from that folder and see if it works.

Now I have to do to install twrp on my device. Please help me.

Hello, I have an NMO_L31 (honor 5c - huawei gr5 mini) device and I have experienced a Failed (remote: image verification error) error when installing TWRP while my phone was unlocked before. have searched from a lot of technology pages to find remedies but all failed. But my God, Jehovah listened to my plea and brought me to @shashank123, I contacted him through XDA and I got him a phone number to make friends on the telegram, he helped me out I and I have overcome the above error. I would like to explain how to overcome the error that I tried. First, I went back to emui 4.1.2 (you can see the instructions then allow OEM unlock, then I update the OTA to emui 5, allow usb debugging when the update is complete. Shift + Right click on CMD (or powershell) and enter "adb devices" to see the connected device, then enter "adb reboot bootloader" then enter "fastboot oem get-bootinfo" To check if the bootloader has been unlocked, then enter the command "fastboot oem unlock (code)" to unlock if the relock bootloader, then if the bootloader has been unlocked then the purpose of the command to factory reset. If that is the case, then go to the phone and see if factory reset is complete. Then develop and reconnect to adb, check the device connected to the "adb devices" command then go to the "adb reboot bootloader" command to get to the fastboot and then use the command "fastboot flash recovery recovery_name.img" (for example : Twrp) "Finally, if the word OKEY appears, you are successful. If you can not solve this problem, please send a message to @shashank123 in XDA and ask for his phone number to make friend through telegram and regular help message because he does not often use XDA. Thank you very much Shashank for helping me. Thanks be to my god JESU CHRIST and JEHOVAH.

No problem at all mate. Helping through telegram was quick in real time rather multiple post or message and then waiting for response from each other. Due to time crunch, I opted to quick help rather keep you waiting all day long
Good you got your phone as per your requirement and able to do what you wanted. Thanks and Enjoy.
You can edit your comment to say "@shashank1320" (use without double quotes) rather Shashank123 as users may send message or qoute him and get no response as that user may or may not exist :silly:

Boot to bootloader again and see the bootloader state if locked or unlocked. Try unlocking it again.
