Honor 6x relock bootloader
Hello, I had the same problem. I was able to relock the bootloader with the standard fastboot command followed by the code provided by Honor for unlocking the bootloader.
phone in bootloader mode
then
fastboot oem relock 1xxxxxxxxxxxxxx8 ( your code)
I have the US versin BLN_L24 but should work on other versions as well
Good luck

Well. Updating to nougat will relock ur bootloader . If u unlock on nougat , a downgrade will again relock bootloader . U can even use the above steps which may work

Remeber, this code is always the same, whether you're locking or unlocking bootloader
Edit: save it somewhere so you can access it when you don't remeber it (example: a doc in google drive saved in the clouds)

TWRP error honor 8 l19

Hi. I have a problem when flashing TWRP on my honor 8 L19. I have unlocked bootloader the official way and Emui 5.0 Android 7.0. When trying to flash TWRP through ADB I get the error: Failed(Remote: Command not allowed) I have tried different TWRP files. I can't factory reset as the recovery needs an update to work properly. I wonder if you have some idea or solution for me? Is there any official software that I can flash? Or point me to some help sites?

Put your twrp file in the adb folder. Open command prompt while you're in that folder

That's what I always do. There is no problem with ADB only that it will not overwrite rescue partition.

Rommco05 said:
This is the problem... Is only one way, you need to make rollback to Marshmallow, isn't another

FRP is security feature by Google. Try find on Google more info

After rollback check this:

Thanks for fast reply. I will try the rolback to mashmallows. Found the nessesery files on Honors support sites.

Have to agree. it was greyed out. Have now done the rollback sucessfully and i oem unlocking i switchable. I have run the phone for some days and it working well on mashmallows. I will now proceed with twrp, backup, root and upgrade to nougat. . Shall i leave OEM unlocking enabled then?

That answer was lightning fast, were you sitting just waiting for me to answer ??

Upgrade to nougat?
I have now unlocked bootloader. OEM unlocked Active, marshmallows, twrp and root. Everything works smooth and perfect When i upgraded to nougat the phone returned to locked bootloader again and (i think) locked OEM. So i had to do the whole process again . Is there any way to upgrade to nougat without getting locked bootloader and OEM? Or is there any nougat Rom thats works?

we cannot stop the locking process while updating,you have to unlock again and root.

@Rommco05 is right. There is no way to turn it on or off because the OEM unlocking button is not solid anymore.

Were you on MM or nougat before this? And accordingly use the correct twrp. The ine you used may be not be the correct one.once the correct twrp installed, you may flash without error 7.
Whats the phone model btw?

You are using incorrect version of trwp. Check in rom section there is one for emui 5 decryption support or in my signature for root method you will direct link there.

all the patched versions for root in the folder "patched boot"
if you need to patch under your version of the firmware, write in the topic, I'll add them to google drive.

@nummerok this looks promising! My sincerest thank you for the effort!
But I do have a rather dumb question. I currently already have the March 1st security patch:
Is there any way I can get root on it? Do I need to patch the firmware that has the February 1st patch, and then use the image from the "patched boot" folder?

It is not in settings. You need to ask @the_laser to give you the signature file for bootloader unlock. I will give you the link.
https://forum.xda-developers.com/showthread.php?p=76065880#post76065880
Go to this link and ask him in private message for the file and then you can unlock bootloader.

All we need not is someone to build a recovery and a stable rom, but there's hardly any support for this device because it's been so hard to unlock the Bootloader
