Solution to Lock Bootloader:- Go to Fastboot Mode,
Type :
fastboot oem relock (Bootloader unlock code without bracket)
I finally submitted my device to service centre
Needed a help in locking bootloader of Honor 8 Pro Indian Variant DUK- L09 C675.
I flashed Latest Oreo update through TWRP with the help of DUK_FullOTA_ROM_flasher method but the bootloader is still unlocked....
If anyone could help me with this as I have to visit service centre related to mic issue.
Connect to your computer, restart to fastboot mode and use "fastboot oem lock". Make sure you have a stock recovery and ROM on it, because the locked bootloader will not boot anything else.

No, it won't. But you should still have a backup whenever you mess with fastboot.

Hi all, I need to relock the bootloader, flashing back stock MM or LP didn't solve the issue for me, neither hard resetting, bootloader is still unlocked and the message appears on every start in the high left corner.
Can You help relock or it's impossible for now please?
It's not possible to relock once it's unlocked. It does tell you this when u unlock it.

thanks for the answer, I did not remember that message. Strange for me that noone found or searched a method to relock for selling the phone :good:
Getting it relocked is the only way to send it back for warranty claim. I wasn't able to get it recognized by my computer so that I can run fastboot comands on it - the right one is ./fastboot oem lock

Did you use the proper fastboot.exe? What OS is your computer? If it's windows try these.
It seems that in order to get fastboot operational, you need to have a working bootloader. So, after a couple (hundred) of tries - DO NOT FLASH KDZ (REFURBISH) your LG G4, it still boots once in a while and if it has your account and data and it will be faster to get to fastboot mode and get the bootloader locked again. Can somebody confirm that you can execute "fastboot oem lock" on an unlocked device? This will save us a lot of time trying to get the device to that state...
for me it is impossibile. If you have a g4 with bootloader locked and you doing fastboot oem unlock it says that it is no possibile...you must follow the instructions that lg provides with file unlock.bin
So is impossibile relock bootloader with fastboot oem lock...I hope that anyone find the way to do it...
Well unfortunately it is not posible to lock the bootloader via "fastboot oem lock" I'm waiting for user @warloxfre for some more info on his ideas (fingerscrossed)
Hi friends
Please give me suggestion or guide how to solve problem about handset booting after mistakenly handset OEM locked through fastboot
It enter to fastboot mode but not going to recovery mode or restart in system mode
Is there any solution
If yes then please help me
fastboot oem unlock ?
Actually ive unlocked OEM and install twrp recovery and installed freedom os
Then while checking OEM status ive enter command fastboot OEM lock
It ask me I've pressed yes after that the massage is came after restart as your device is corrupt it can't be trusted and will not boot
After that it enter to fastboot but not going to recovery mode or system
While type command in fastboot OEM unlock massege come failed
This happens because your bootloader has been unlocked at one time. There is no going back, even if you use "fastboot oem lock" later.
Edit: Just noticed the part about your device will not boot. You need to find the system image and flash it. I read somewhere today that OnePlus just released the system image for 4.7.4.
Can you unlock again?
@op, IMHO the best possible solution will be to flash stock rom image and stock recovery if required but I think when you flash stock image it will also flash stock recovery.
When you turn off the phone and boot it with VOLUME UP plus POWER, this should send you straight away to Fastboot. Try if you can unlock again, otherwise... bad luck - you'll need a restore session with 1+.

Not to be unrespectful, but you're wrong, it is absolutely possible to relock bootloader without problems.
IMHO, trouble happened because he had a custom rom onboard... and a locked bootloader does exactly its purpose... to not boot insecure firmware!

After looking into it further, I agree with you. That's what I get for having a bootloader-locked Samsung device for two years. I must be getting rusty!
Yes, the bootloader can be re-locked. There may still be a tamper flag as with previous OnePlus devices. But having a locked bootloader with non-OEM software would likely cause the problem he is describing. So, he needs to flash the factory image from bootloader.
I've requested to 1+support for restore remote session
Support send me file link and l2 will assist me in within 2 days
DO NOT RELOCK BOOTLOADER UNLESS U READ UP FIRST!!!!!, its worth just waiting the few seconds after reboot, then to go and try to relock the bootloader

Did you by any chance re-lock the bootloader with a custom recovery and custom ROM flashed?
It's because of custom recovery.
Just flash stock recovery image before locking the bootloader.
This fixed for me.

You unlocked bootloader, flashed rom (custom) and relocked bootloader? Never lock your bootloader on a custom rom! Just enter fastboot again flash twrp (manual/force reboot recovery), copy internal storage to pc then wipe/format everything. Format data. Factory reset then flash latest official rom and reboot

the re-lock and un-lock bootloader function,
is it the same as the OEM lock and unlock option in developer mode ?
pardon me if this is a noob question but i really

Hey guys, Is IT possible to unlock bootloader without approval trom xiaomi? I used mi unlock app on my Pc before approval, and It seems that my phone Is succesfully unlocked. Even in console on Pc it days that the device Is unlocked.
However, I can't flash twrp (It still boots into factory recovery), so I cannot root.
Any help on this case? Do I still need approval and do unlock process again after that?

What happens when you flash twrp?I mean it says failed or successful.
You can run this fastboot command to get bootloader status: fastboot oem device-info

Actually..I got it to work. But when it booted into twrp, I doesn't have magisk copied on phone storage.
Then I tried to reboot phone normally, but I got bootloop. Then I flashed fastboot rom and then it booted into system, but my phone is locked again.
As the title says my Red Magic 6S RPO is locked with a security pin and a google FRP. . So is there anyway to unlock FRP or bypass it to use the phone.
have you tried MI Unlock Tool to unlock the bootloader for Red Magic?
I saw on Chinese Sites everyone is using Mi Unlock Took To Unlock bootloader For Red Magic
Can you please try and confirm?

Make sure you turn on developer mode and turn on the OEM Unlocking
Then go to fastboot mode using the command
adb.exe reboot bootloader
First try these commands in fastboot mode
Just to make sure that your device is available in fastboot mode.
fastboot devices
one of them should unlock the bootloader
fastboot flashing unlock
fastboot oem unlock
The following command should give you info if your boot loader is locked. this is to confirm if boot loader is unlocked or not.
fastboot oem device-info
Can you please try these commands and let us know
if these commands fail to unlock the bootloader then try the miui unlock tool
you have a global Firmware or China Firmware?
