How to re-lock bootloader, remove twrp and unroot mate 8 L09 - Mate 8 General

Is there somehow I can RE-lock the bootloader, UN-root my mate 8 - L09 and reset everything like it was when it was new?
edit:
This is what I have done until now.
- flashed to stock recovery (phone is not rooted any more)
- factory reset
Then when I try to relock the the bootloader , I get message FAILED (remote: root type is risk)
fastboot oem relock ****************
...
FAILED (remote: root type is risk)
finished. total time: 0.970s
Someone know how to resolve this issue?
Could this be fixed by installing fresh and untouched complete firmware from huawei?
If yes, some know which link to use for my device and version?
Model number: HUAWEI NXT-L09
Buld number: NXT-L09C432B152
All help is highly apprechiated.

Can someone please delete this thread - I created a new thread in the troubleshooting section.

help on relocking the bootloader.

Hi All,
Can someone guide me to relock the bootloader? I'm getting the error below.
FAILED (remote: root type is risk)
Thanks in advance.
Try the solution posted by FineFeather (post #15) in this thread: Problem re-lock bootloader (remote: root type is risk) - NXT-L09
Different Huawei phones, but the principle should be the same. Just make sure to use the stock recovery & stock rom of your phone's exact full model number.
Bit of a longer method posted here by DigiGoon for the Honor 7 (again, use a rom meant for your phone's exact full model only): https://forum.xda-developers.com/showpost.php?p=64227910&postcount=8

Problems with unlock/relock bootloader and TWRP flashing

Hi, I have Asia-Pacific version of the Huawei Mediapad M3 (BTV-W09C209B005). I'm trying to flash TWRP to gain root access, but I'm encountering problems in the preliminary stage. I've searched for similar problems in the forum, but couldn't find a solution that works for me.
So here are the steps I've done:
1. I received the official bootloader code from Huawei.
2. I used ADB and Fastboot to unlock the bootloader, but I noticed something peculiar: the screen says
Phone UNLOCKED
FRP UNLOCKED
I am the first owner of the tablet, so I was surprised to see that it was already unlocked. In any case, I tried the fastboot oem unlock command, and it returned this error:
FAILED (remote: password wrong)
3. I tried to proceed to TWRP flash on the assumption that the phone was already unlocked. But I get this error:
sending 'recovery' (23794 KB)....
OKAY [ 0.740s]
writing 'recovery'...
FAILED (remote: Command not allowed)
finished, total time: 0.740s
4. I tried relocking the bootloader, as per several XDA threads, before unlocking again. But I once again encounter an error:
FAILED (remote: stat not match)
I already contacted Huawei to make sure that the unlock code they sent me was correct, but I doubt that it'd be wrong because they probably just paste it after generating it in the system.
Any ideas how to proceed?
Interesting, first off if you want to check and see if you phone is BL is unlocked go to Settings, Developer Options and see if your OEM unlocking is grayed or doesn't move..if it doesn't move or grayed out then it's unlocked.. if it moves the it not unlocked.. check that your fastboot /adb are set up correctly. Though the easiest way to this ( unlocking the BL and flashng TWRP) would be to get Huawei Multi-Tool v8 by Team MT and use it,, ( grab the one in the Honor 8, as I know it does work) and make sure you ave the correct TWRP for your tablet..

Thanks for pointing me the Huawei multi-tool. So I tried that, and as suspected, the device is still locked. I am able to toggle the OEM unlocking and the tool says so through the lock status (oem lock-state info LOCKED). I proceeded unlocking with the tool, but I received the same error: FAILED (remote: password wrong)
The unlock code doesn't seem to be the problem because the tool displayed the corresponding serial number and it was a match. So there's something preventing me from unlocking the bootloader--it's probably the same reason why the fastboot says "PHONE Unlocked" even though it actually isn't. Again, I can't do the relock trick because the device wouldn't accept the Huwei unlock code.
Thoughts?
Hmm, why do some of these seem to be so picky when it comes to unlocking.. The multi too will copy what ever code you but in, sorry for the questions just trying to help narrow it down.. in the developer section there are 3 things that need to be ticked,, OEM unlocking, USB debugging and and allow ADB debugging in charge only mode.. Maybe you software got out of wack.. read here ( https://forum.xda-developers.com/mediapad-m3/help/bricked-mediapad-m3-t3746893) as it may help.. Not sure if HiSuite can restore it.
OEM unlocking and USB debugging are "working" in the sense that I can send commands from the PC via USB. It's just that I can't properly unlock the phone. I updated the drivers to see if that's the problem, but I still encounter the same error. I basically couldn't move forward with the link you sent because the first step was to unlock the device and I couldn't get past that. When I try to unlock the error is still 'FAILED (remote: password wrong)'.
I've seen some threads from other Huawei devices that suggest rolling back the firmware, but this is the first time I'm trying to root this device. And it's still on Marshmallow, which is the version that came with the first release of the Mediapad M3, so basically there's nothing to roll back to.
Why not upgrade to 7 as that is where most of the newer threads are written for plus it will redo your boot loader... giving you a clean slate to work with..and that might be your issue..
I can't update to 7 because Huawei stopped providing updates for my region. I failed to mention that the reason why I'm trying to unlock the device is to change the region and upgrade to 7.
May I ask where you are?
From Southeast Asia, but the tablet was imported from China. I planned to convert it to the European version so I can at least upgrade to Nougat. I'm still stuck though.
So Huawei sent me a new unlock key and it works! Problem solved!

How to install stock rom

I had several ROMs on my pP9 lite and after some time I decidet to unroot and go stock again. I don't remember how, but a locked the bootloader and installed stock rom.. everything OK, but after an OTA update I got no bluetooth and I can't install now any other rom cuz I lost my OEM unlock code and now I can't get it from Huawei... When I go to fastboot, I have PHONE Unlocked and FRP Unlocked too, but I can't flash the recovery... it's like the bootloader is unlocked, but it don't let me flash my EliteTWRP image... I get FAILED (remote: Command not allowed)
Any sugestions on how to fix this? I want to give this phone to my nephew, it is still a good phone for some games and whatsapp

Hello,
even if it says it's unlocked, it's actually locked.
So you need to unlock it again if you want to flash stuffs...
Good luck
P.S.: About your other post... You cannot flash with dload method on android 7,
you need to use Elite recovery and HWOTA method or Huawei Recovery Updater to flash the firmware
you want. ( be sure you choose the correct firmware )
Cheers

Hello,
take a look at the UNIFIED HELP THREAD,
post#6 ---- UNBRICKING AND DOWNGRADING FROM EMUI 5
where it is well explained how to use the rollback package.
You need the marshmallow version of your ROM stock.
Ex: VNS-L31 Rollback Package + VNS-L31 (C432 or C185 or others) B160 / 1,
depends on whether dual or single SIM or others available for your CUST / Region (C432 or others).
Follow the procedure carefully ...
Cheers
