Help please.

Hello so I'm using Huawei P9 lite
VNS-L21
And after unlocking bootloader I receive this message when I'm rebooting it:
Your device has been unlocked and can't be trusted
How to get rid of it? Because I want to sell this phone..
I really don't know how to relock it so please anyone help me.
P.s I have been flashed TWRP via fastboot..

I'm afraid you can't, the only way is to relock the bootloader

Bricked P9 lite L21 SS

Hello I have managed to brick my P9 lite with the nougat rom. I can only access bootloader, the phone is both oem and bootloader unlocked and currently it's on bootloop. I have tried the upgrade with 3 buttons pushed but I can't get the phone to accept the package(put in the dload folder on SDcard) it only shows 'install failed - Incompatibility with current version please download the correct package'. I have also tried the fastboot flash system command it went without errors but the only result is that it no longer bootloops and only shows black screen after the warning that I have unlocked bootloader. So is there anything else I should try? Thanks.

Fastboot??

Try this

@mrmajco
I don't understand what you mean. Could you give me some commands to use? If I flash recovery with fastboot I can't get into the recovery (nougat rom) and if I flash system with fastboot flash system I only see black screen and nothing boots up.
fastboot flash zip gives me FAILED command not allowed.
@zgomot
Well, either I'm really dumb or doing it wrong but once I flash the meticulus recovery with fastboot flash recovery recovery.img nothing really changes and I can't get into the recovery.
To flashing oem info I get FAILED (remote: command not allowed). I will post it here but I doubt it will be of any help.
IMAGE
edit: I really don't know how but I'm in the recovery so I think I will manage to flash the stock image from there and make it work. I will once I resolve the problem or brick it once more Thank you for the link.

cant flash recovery on B161 bootloader unlocked but also wont lock again!

Hi guys,
I am trying to flash the OEM info as its currently on according to DC unlocker:
Found Phone : VNS-L11
Model : Huawei HiSilicon Kirin Android phone
IMEI : 860921031654789
Firmware : VNS-C900B161
SIM Lock status : unlocked
my phone about device screen displays:
Model: HUAWEI VNS-L31
BUILD : VNS-L31C432B161
EMUI 4.1.1
ANDROID 6.0
I have downgraded to MM B161 thinking this will help and has factory reset my phone during the process but no luck.
I get a boot-loader unlocked warning since i was on nougat, and unable to lock or unlock the boot-loader when i try.
when trying to flash TWRP recovery i get: FAILED (remote: image verification error)
OEM UNLOCK is enabled and so is DEBUGGING
any ideas, really be great to get this fixed finally

Try to download again TWRP the use the command:
fastboot flash recovery twrp.img

Huawei p9 hardbrick, cannot resolve the problem

Hello mates!
Yesterday I accidentally bricked my phone and I spent ours and ours on this and others forums to find solution but without succes, so here is what was happen:
I was on L21C432B380 firmware, stock, bootloader locked, without root acces. So I tried to flash ROM 7.1.2 AOSP by Meticulus. I followed step by step guide. I succesfully unlocked bootloader using fastboot. Then I flashed TWRP again using fastboot so I can downgrade to EMUI 4.X and that was succesfull also. After that I flashed oem-info using TWRP and flashed stock UPDATE.ZIP using three button method, both succesfully but when phone tried to boots up It shows message "No OS installed".
My entire system and data was deleted, there is no recovery, bootloader is again locked, I have only managed to get into fastboot mode using adb
Every single command I tryed to run in cmd results in this message: "FAILED (remote: Command not allowed)
Somehow I need to install Firmware using fastboot but don't know how cause bootloader is again locked
My knowledge about this things is above average but I cannot "google" the problem
Please help and thanks in adavnce

Hello man,
Dont know why u do that (downgrade to MM)...
Explicitly written for flash AOSP 7.1.2 to be on emui5 (were u was)...
Flashing oem also relocked your bootloader (written ton of times in threads)....
Now using fastboot re-unlock bootloader re-flash TWRP.
If u maked a full backup just use it, otherwise try to follow this guide..

Hope u will resolve.

A2017G How to relock bootloader on Nougat B10

I came back from LOS 16.0. Flashed A2017G_B10_NOUGAT_FULL_EDL in EDL but there's a warning that my bootloader is locked. I wanted to relock it but the warning prevents me from entering bootloader or fastboot (or maybe they are not even present....). Next I flashed A2017U_FASTBOOT_UNLOCK_EDL in MiFlash but it did not do anything. It flashed OK but I still cannot access fastboot. Should I flash some marshmallow rom? Thanks in advance.

I have the same problem. Cannot enter fastboot mode on Nougat ROM.

Ok I found the way usin Axon 7 Toolkit
1. Set the Android version to 7 using option 13
2. Perform unlock bootloader
Following instruction Axon & Tookit gives you EDL image of the proper fastboot partition giving the possibility to enter fastboot mode
then fasboot oem lock

I wanted to say thanks that works, but apparently my phone is bricked now - it hangs on green ZTE logo. PC recognizes it as DFU. Cannot enter EDL either. I guess I look for some guide how to recover from this situation
Managed to fix that. Somehow I was able to enter fastboot. It said my bootloader was locked so i flashed TWRP and from TWRP using ADB installed stock Nougat rom

If you was able flash twrp mens your boolaeder was unlocked?

No there's a TWRP that works on locked bootloader.

Seems that TWRP was inatlled before the bootloder was locked again.
