in bootloader screen i can see in red « PHONE Unlocked » and just under in green « FRP Lock ».
in nougat settings, OEM unlock is grayed out in disabled position in settings (maybe it's normal as i unlocked the bootloader already).
i already flashed before successfully TWRP and stock recovery both in MM and nougat without problem, but it's not working anymore.
« flashboot oem lock », « flashboot boot », etc… are giving the same error. only basic things like « fastboot » reboot works.
I googled for hours my problem, it's all about people having their bootloader not unlocked.
Any idea?
Well, i reply to myself, the FRP Lock was the problem, and a bug in B301 prevented me from setting this to off, i had to do a rollback procedure to EMUI4 (rollback update + full firmware update) so that i could disable FRP lock by setting the OEM unlock option (which way available after 2 reboots).
be prepared to have backups, hopefully one day we will have full firmware for nougat available!
edit: dunno how to mark a thread as « solved »

Well, i placed the rollback files in dload folder of the external sd card then i entered recovery to apply it.
It is not normal that you can't enter any recovery, you shall try the 4 combinations to be sure (boot with or without the cable connected, and with either vol up or vol down), one of the combination will bring you to fastboot and another to the installed recovery. Try also with both up and down pressed just in case ^^

Hi.
I´ve unlocked the bootloader on my P10 plus.
But now, the toggle to unlock OEM on the developer settings is greyed and I can´t perform any fastboot commands.
Any help?
Thanks
I believe the option becomes disabled when you've unlocked the bootloader, as you'd have to use the relock command instead of the toggle to relock it.
I assume you're familiar with accessing and using fastboot if you've unlocked your bootloader... so for the fastboot commands, does the device show up when plugged in and you run "fastboot devices"?

i have my huawei p10 plus doing the same thing of yours.....only erecovery mode and when i get to boot in fastboot mode is only fatboot mode & rescue and i had locked bootloader and frp lock.....but i was reading that huawei just block the page to unlock bootloader i just dont know why they did that /......
Maybe try re-unlocking and flashing stock rom, kernel, system, and boot. (Or you can try the method I used to update manually). Requires to be able to acces external sd card.
Hmu if you want to know how.
Hi,
I've tried all the following steps in the video and I got the error "flashing lock is not allowed". I've already flashed stock rom and recovery and wiped the phone so it's as stock as it gets yet I still get the same error when I enter "fastboot oem lock". Please help ASAP!!!! I'm trying to update to Android 8.0 but the update keeps failing because my bootloader is unlocked
Thanks in advanced.

Go to developer settings.. check the oem unlock option. If it's off, bootloader won't relock. You need to turn it on. If it's greyed out & can't be turned on, then you need to root your firmware or flash custom rom & turn it on.
When you have this problem, only magisk will help you turn on allow bootloader unlocked when it's grayed out.
So, you have to flash magisk, turn on allow bootloader to be unlocked in devlopper settings, then flash a clean OOS, make sure there's no modification like custom recovery or root, then relock your bootloader.
Good luck!
use command "fastboot flashing lock" instead of "fastboot oem lock", this will lock your bootloader
hope this tutorial will help you....!!! https://www.youtube.com/watch?v=CQYCSdDUdAU
I had the same problem and solved using magistik, reenable unlock volta loader and After relock.
Hi could I ask because i lock my bootloader on Mi A1 but unfortunately the device didn't boot up.
Now, I am trying to unlock bootloader to fix my device and it won't unlock FAILED (remote: oem unlock is not allowed).
I am on May latest security patch build. Please help me.
Did you try reflashing ROM with Mi Flash tool? Use "Save user data" option there.

I think you tried to lock your phone after rooting your device. You'll have to try to switch to fastboot mode by volume down + power after vibration. Then use flash using Mi flash tool
I cannot do that, the bootloader is locked and I am on May security patched. Those fastbook oem unlock and fastboot flashing unlock methods won't work. I believe only testpoint is the solution to my problem.
Stuck with the exact same problem....did u find the solution

Reboot to fastboot power+volume down then reboot to edl mode by typing "fastboot oem edl" in your adb your phone will turn black. Open miflash and click "refresh" if you see "com#X" it means its connected then flash the fasboot file you downloaded in mi forums after finish press and hold power until it restarts.
I'm having Mate 10 lite(Nova 2i aka Honor 9i). The device is now in soft brick state.
Device current state.
OEM - locked
Bootloader- locked
Recovery- EMUI
Huawei eRecovery- EMUI
What I have done so far.
Downloaded the firmware from Huawei Firmware Finder and tried forced update option , Firmware: RNE-L21 8.0.0.311(C185).
Response- Failed
Flash TWRP , Response- Since OEM lock and Bootloader is locked. Can't flash.
I'm having Lock code. But OEM lock via USB debugging cannot be turned ON since device is soft bricked. :crying:
In attachments I've uploaded "about phone", OEM & Bootloader status, Recovery.
If anyone has any solution please share.
did you try doing a factory reset?
if not then try once
if that dsnt work boot into fastboot and connect device and type this in CMD "fastboot -w"
this will erase everything from your phone even all data
then try booting up the device and then try unlocking the device
I will create a thread tonight for how to unbrick honor 9i.
do check that tonight you will be able to get back to EMUI8.0
although for you, u will need the bootloader unlock code as your device is locked
I have a A2017U that I just downgraded to B35 using this guide: https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-universal-unbrick-t3814413
I want to lock the bootloader to stop the annoying boot warning but can't get into fastboot when using AXON7TOOLKIT.
I tried flashing A2017U_FASTBOOT_UNLOCK_EDL (downloaded from https://forum.xda-developers.com/axon-7/how-to/complete-guide-to-unlocking-installing-t3561128) through miFlash but I still can't get into the bootloader.
What can I do?
EDIT: Thanks everyone! I used the toolkit to unlock the bootloader again, then locked it. For some reason I couldn't access the bootloader even though i got the bootloader ulocked warning.

You only want to lock it because of the boot warning? There are flashables to get rid of that... I dom't know which exact files there are for stock B35 or Oreo but there are some going around.
hell you could even go custom and use the splash bootstack if you wanted.
If you want to lock anyways, you have to get an A2017U B19 package and flash it via EDL Tool (or MiFlash). Right after that you'll have fastboot. enable oem unlocking then enter fastboot and issue fastboot oem lock and you're done. But it's way too overkill if you want to just get rid of the 5 sec screen

you need to flash original stock rom for your device trough edl. (rom your device came from factory,marshmallow)
then boot into system,unlock developer options.Allow oem unlock and turn on usb debugging.Now connect phone to laptop and check the dialogue on your phone that ask for usb debug.Unplug phone.
When you did this you want to flash TWRP trough EDL.
Now boot in TWRP and flash UnlockbootloaderPackage from DrakenFX.
Reboot system.
Now turn off your device and boot into fastboot,connect your phone with laptop and open ADB terminal on your laptop or use Axon7toolkit.
In terminal enter fastboot oem lock,or in axon7toolkit choose lock bootloader.
Your bootloader is now locked.
PS: you dont need locked bootloader to recieve ota's,and make sure you are on the firmware your device came shipped with!!
You need a locked bootloader to get rid of the warning message ( dont flash any mod package that claims it delete the warning page)
