Hello mens,
i need a little help with locking bootloader on my Moto G6 (and flash stock rom). I try some treble rom and after that i want to go on stock, so i want to follow this tutorial https://animetrick.com/flash-stock-rom-moto-g6-plus-locked-bootloader-2018/ but without succes. My problem is that i cant swich off "enable oem unlock" from developer setting (it is grey and untouchable) and cant lock bootloader before flashing stock rom. Anybody know some solution ?
I don't think you can lock the bootloader before flashing stock. With a locked bootloader you can't modify system partition. Forget about the switch. Just install stock rom and then relock your bootloader using the guide. When you follow the guide, which doesn't mention the switch, you will reflash stock via fastboot commands, and relock the bootloader via fastboot. Pretty sure the switch will rest itself.

So, i decide use mobile with root and Magis, so I flash Rom, patched boot image and use phone in this status. Now I look into settings and OEM unlocking button is available. WTF ?
Just saying if your attempting to relock the bootloader to do a warranty replacement you cant. The bootloader can be unlocked and Moto even tells you how to. But once you unlock the bootloader once the warranty is void weather you relock it or not. In fact even requesting the unlock key can void the warranty.
To block the bootloader you need to re-authorize unlocking it in the developer options with the OEM unlock button. If the OEM unlock button is gray and unavailable you need to install root and then the button will unlock. Sam had such a situation and write what I did to make everything went without error.
Of course, USB and ADB drivers must be installed.
- Install ROOT, start the device
- Go to the developer options on your phone
- Enable authorization to unlock with the OEM unlock button
- Enable USB debugging
- Unpack the system files to a folder with ADB
- Unpack the file "FLASH_OEM_LOCK.zip" to the same folder (download below)
- Start the phone in bootloader mode and connect to the computer
- Click on the file "FLASH_OEM_LOCK.bat"
- After the procedure the phone will boot, the bootloader will be blocked, and in the developer's options the "OEM unlock" button will be available
Note: The procedure erases all data, the phone will start up as "New" with a clean system.
I did it for my own needs but maybe it will help someone.
Tested on my Moto G6 (XT1925-5)
I try to relock my Moto G6plus xt1926-3 also with stockrom flashed (after trying lineageos) but have some problems.
I cant flash something after the two "fastboot flash oem lock". It gives "remote failure" (bootloader flash permisson...) error.
After relock with oem lock, a message "incompatible operating system" is displayed before boot.
But I can unlock it again without problems. (and install magisk for example or boot twrp).
I can switch the oem unlock in dev settings to on too (in unlocked boot), but the script gave me same error.
I want only to revert to stockrom (-89 or older) and locked bootloader.
What am I doing wrong?
I could flash with locked bootloader (magisk, enable option in dev and proper fastboot version)
But I get the message "your device has loaded a different operation system"... I have flashed complete stock
*weird*
EDIT: unlocked, flashed bootloader again and relocked, but message keeps.
Have the same issue. I tried to relock my Moto G6plus xt1926-3 Android Pie also with stockrom flashed (after Ressurrection) but had some problems.
I couldnt flash anything after the two "fastboot flash oem lock". It gives "remote failure" (bootloader flash permisson...) error.
After relock with oem lock, a message "incompatible operating system" is displayed in boot.

Hi? have you tried this https://forum.xda-developers.com/g6-plus/how-to/2-returning-to-stock-t3854243 ?
I have a Huawei P9 and I rooted this previously and installed TWRP. Everything was fine and and just recently I flashed stock recovery so I can update my phone and relocked bootloader. When I locked it, it tried to restore to factory settings as it usually does and I get a prompt “wipe cache partition” or wipe something. I now can’t remember as I just absently tapped “yes.” And after that the phone was bricked. It tries to restore using eRecovery but always fails. I can’t flash through fastboot as the phone can’t be detected. Please help.

What was your last action before you went to (re)lock Bootloader:
a) Flashing stock Recovery, and in that case did you unroot and are you sure it was correct Recovery version for the stock firmware you were running
or
b) Updating Firmware, and in that case by which method did you update (OTA, eReovery, HiSuite, DLOAD, Firmware Finder + DNS, HWOTA...)?
What is your model L09 or L19, your cust c432 or else, what was your full build name/number (like EVA-L09c432b504 or what)?

I tried updating my phone using the dload method but it kept failing. I also used a lot of firmwares. Btw my phone is EVA-L19 and I live in the Philippines and got my phone here. I only used the Asia firmwares as I can't seem to find a Philippine specific firmware. I did not unroot before relocking the bootloader.

Before relocking Bootloader you must make sure that you have stock Recovery, stock Boot/Ramdisk image (that is, must be unrooted), stock Kernel (if you experimented with custom Kernels).
Unfortunately, if you didn't have, Factory reset as part of relocking Bootloader fails and may cause brick
Don't know what is the cust for Philippines/Asia and what are its latest firmware versions, and do they allow DLOAD installations (only firmwares named as FullOTA-MFPV on Firmware Finder can be installed by DLOAD, those with MF but without PV cannot be).
Btw, what is the cust for Asia you were flashing with, EVA-L19cXXX?
If eRecovery cannot recognize the phone model, it might be due your attempts to flash various firmwares by DLOAD
Can you boot to Fastboot and connect by Fastboot from PC (probably no more since you attempted to relock Bootloader, which disabled OEM Unlock and USB debugging):
- Switch off, connect by USB to PC, press and keep pressing Vol- and press Pow button.
If you could boot to Fastboot, there are Fastboot commands to read what the phone thinks it is its latest cust and build number, that can help to unbrick.
Also, it helps to DC-Phoenix (paid tool for unbricking)
PS: Don't know why people go for relocking Bootloader. There have been so many posts here and there with users who bricked their phones when attempting to re-lock Bootloader(because they had TWRP, they did not unroot, they had custom DOMs, etc).
Besides:
- Unlocked Bootloader DOES NOT prevent/affect OTA upgrades
- relocked Bootloader is different from originally locked Bootloader and Huawei service can still recognize that Bootloader was unlocked and relocked
- Some new stock firmwares automatically lock (not relock) Bootloaders upon upgrades
I can boot to fastboot but all of the tutorials I’ve read says that the bootloader needs to be unlocked in order to upgrade firmware or unbrick. And the only commend I can do in fastboot is “fastboot devices.”

As per your Fastboot - your Bootloader is still Unlocked
Hence flash TWRP for Nougat (from Fastboot) and use HWOTA method:
https://forum.xda-developers.com/showpost.php?p=75787156&postcount=3
to flash EVA-L19C636B398.
It must be FullOTA-MF, it is explained in the link above what you need to prepare (HWOTA folder on the SD card, that contains three PROPERLY renamed update*.zip files that you must find and download by Firmware Finder, you can use FF on PC).
It can be any other NOUGAT stock firmware (not necessarily b398) but it must be for EVA-L19c636 (by HWOTA alone you cannot rebrand to eg c432) and it must be FullOTA-MF (or MFPV), usually 2+ GB, not some OTA-MF of only 300 MB or so.
You must use the same TWRP for Nougat that you will find in the post #1, from the same thread as above, where is HWOTA method describef in the post #3.
If you use Windows 10 on the PC, (by default it hides file extensions) make sure that you do not rename some of the three update*.zip files to have 'double' zip extensions like update*.zip.zip
In HWOTA method, TWRP will execute a shell script and files and folders must be named exactly as described in the given OP post, otherwise HWOTA method (its shell script) will fail to flash the complete firmware
@zgfg sorry for disturb

People, this has been written in many other threads and posts:
- Before doing Bootloader relock or Factory reset, you must unroot, restore stock Recovery, otherwise it bricks.
You can try to reinstall by using eRecovery.
But since you still have TWRP, read my post #8, you have link and instructions to the HWOTA method.
Of course, I have described to the other user who has L19c636, you must flash by HWOTA for your model L09/L19 and your cust cXXX - I gave instructions in the posts #4 and #6 how to boot to Fastboot and which Fastboot commands to use to obtain info for your phone

I followed all the steps and downloaded all files and put them into HWOTA and rebooted. Nothing happens. I tried Vol+, Vol-, and Power button to force to install files but I get install failed. BTW when I boot I'm always on eRecovery and cannot boot to TWRP.

Nothing can happen by itself
>> . I tried Vol+, Vol-, and Power button to force to install files
This is HWOTA, not DLOAD.
It's desrcribed in the HWOTA tutorial that you must boot to TWRP, and TWRP has Install tab where you choose Storage (SD card), Zip installation, and then select the script from HWOTA folder, and then Swipe to start flashing
>> when I boot I'm always on eRecovery and cannot boot to TWRP
I wrote you in the previous post that you must first install TWRP. Your Bootloader says it is unlocked.
You must install TWRP from the thread I gave you the HWOTA link - do you know how to install TWRP from Fastboot?
Have the HWOTA folder ready on the SD card, so that when you install TWRP from Fastboot, you must immediately reboot from Fastboot directly to TWRP, then navigate in TWRP to it's Install option and proceed by HWOTA installation as described in its OP post
I tried installing TWRP in fastboot mode using “fastboot flash recovery” command but it always fails. Btw I can only boot to eRecovery so the developer options and usb debugging that needs to be toggled cannot be done. Cause in all tutorials to flash TWRP, usb debugging needs to be toggled.

Please describe how flashing TWRP fails - what exactly does the Fastboot respond to the command.
Please copy/paste your command and the Fastboot response from the PC
And please upload also a photo of the phone Fastboot screen, what exactly it says on the bottom (Phone unlocked...)

From your Fastboot screen photo:
- Phone relocked (green)
Hence Bootloader is really relocked, but this is in contradiction to
>> Bootloader unlocked
what was reported by Fastboot interrogation from the PC side, post #7
Btw, you see that Fastboot screen says Phone (=Bootloader) relocked (it was unlocked and then locked) clearly distinguishing from the originally locked phone (Bootloader) ;-(
Fastboot also shows
- FRP locked (green)
which confirms that OEM is locked.
Btw, did you maybe locked OEM from Settings, Developer options before you went to relock Bootloader by Fastboot?
Unfortunately, you got what you wanted, the locked Bootloader and also locked OEM - but since the phone is bricked (you didn't prepare to have stock and unrooted firmware with stock Recovery before attempting to relock Bootloader), you cannot unbrick the phone now:
- Methods require to have or to flash TWRP (like HWOTA)
- Or to flash stock Recovery, etc:

- Or to flash no-check Recovery:
https://forum.xda-developers.com/p9/development/eva-nocheck-recovery-flash-unapproved-t3705125
But you locked Bootloader and they cannot flash anything.
Because OEM is also locked, you cannot unlock Bootloader.
And you cannot boot to System to unlock OEM (on the bricked phone).
Btw, it was much more useful working phone with unlocked Bootloader and OEM (bothering with a Notice on the start screen) but available for unbricking (just in case), than now the phone with locked Bootloader and OEM albeit bricked ;-(
I hope, somebody else a wannabe with the relocked Bootloader will read this (they don't, every month or so another one does the same or similar and only then turn to XDA asking for help)

Anyway, you can try:
1) Download by Firmware Finder (from another phone, needs not to be Huawei, you can install FF from GStore to any Android) or from PC, EVA-L19c636b395 FullOTA-MFPV (package number #114776, 2.5 GB) as on the screenshot.
Try to DLOAD.
No guarantee that it could work (your phone remembers b398 and there is no MFPV with c636 but b398 or higher)
2) Try to rollback to Marshmallow, maybe it will allow you to do it by DLOAD:
https://forum.xda-developers.com/p9/help/finally-downgrade-huawei-p9-android-t3868721
Once on Marshmallow (but with unbricked phone), update by OTA back to Nougat
Sorry, I don't know any other (free) method (all others require flashing, but you cannot since the Bootloader OEM are locked)
You can try paid services, people were able to unbrick (with locked Bootloader and OEM) by using their tools, but you must directly communicate over the Web links, pay them and ask for instructions:
