[Q] unlock bootloader logo

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.

How can I lock my bootloader?

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?

How to Lock Bootloader?

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.

Bootloader LOCK..No Recovery..cant boot..HELP?!!

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.

Bootloader relock automatically

hi, I tried to follow this guide but every time I unlock the bootloader, after reboot is again blocked.
Can you tell me why this happens?
I have already given permissions to "Enable OEM Unlock".
Thanks
