Is it possible to completely lock my my bootloader after unlocking it?
I used fastboot oem lock and now it says RELOCKED in fastboot. I also got rid of the security warning flag. Next I'd like to get a complete lock so I enter fastboot oem writesecureflag 3 which hangs the bootloader and doesn't fix my problem. has anyone yet been able to obtain complete LOCK?

I will receive my galaxy nexus few hours later and plan to unlock my phone. Is there a way to hide the unlock logo after I unlock the bootloader or Can I unlock the bootloader, then root the phone and relock the bootloader after to clear the logo but still get the root access. If yes, then how to relock the bootloader?
fastboot oem lock will re-lock the bootloader
But will I still get the root access of my phone after I relock the bootloader and will the unlock logo disappear when boot up after I relock the bootloader?
p.s. It is retail version
why do you need it locked?
I don't like the unlock logo at bootup and the warranty detail only state that I will lost the warranty if I unlock the bootloader, so relock it in case I need warranty, it may cheat them
so then you relock it if you need to. Development for this phone is very young right now so you'll likely be doing alot of flashing. I flash different rom/kernel combinations probably 3-5 times a day with how often things are updating right now. Besides the little unlock symbol is pretty awesome
I know the development is young, that's why I post this. I just need to confirm
1) Is it possible to relock the bootloader in retail version
2) Will the unlock logo disappear after relock
3) Will the phone can still get the root access after relock the bootloader
Thx very much and please reply me if anyone know!!

1) Yes, "fastboot oem lock"
2) Yes
3) Yes, while "fastboot oem lock" does not touch any of your data, "fastboot oem unlock WILL delete all your data. None of these processes can remove root access, the only way to remove it is to reflash the system partition, either by flashing it manually or through an OTA update.
Thx Thx Thx Thx very much
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)
Just flashed the ROM to latest stock and want to lock the bootloader. Nexus root toolkit needs oem unlocking enabled but it's greyed out so it can't do anything while in the desktop.
If I restart into fastboot mode and try using nexus root toolkit to lock it it restarts the phone which leads me back to where I was.
Anyone give me some pointers to get this done? Thanks.
You want to lock the bootloader?
Yes.
@Ryrynz: fastboot flashing lock or fastboot oem lock
Fastboot OEM. Want it completely stock.
@Ryrynz: I meant: use one of the both commands and it's done
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.

Relocking bootloader by this method will erase all data?

No, it won't. But you should still have a backup whenever you mess with fastboot.
After tried to install stock rom on my pixel2 xl, i locked bootloader.
Now, i cant unlock bootloader because i cant boot and check oem unlock.
When try to boot into recovery, and boot to android, just appear message "can't find valid operating system"
What to do?
I tried unlock bootloader from adb, and get the message that is not allowed in lock state
Everything i can is boot in fastboot mode.
Is there any possibility to unlock bootloader without check OEM unlock, because i cant boot anything?
Please help.

Why did you lock the bootloader anyway?? If you can't get to the OS to check OEM unlocking and USB debugging....your hosed as far as unlocking the bootloader again. And since you have no recovery now, you can't side load an OTA to get your OS back. Might as well RMA it I'm afraid
Please people, read this and understand me clearly...
Unless you have a very very VERY good reason to relock the bootloader. DO NOT. The risk is too great for no reward.
This is the second or maybe the third post this week alone where someone may have hosed their phone doing just this...
I'm not here to hammer the OP but folks gotta understand.
