Hey guys, selling my V30 but i unlocked the bootloader. Its an official UK model.
How do i go around relocking the bootloader and removing all trace that i unlocked it.
Can i just use the bootloader oem lock command or something similar?
Thanks.
Flash a kdz for H930 of your choice first (REFURBISH option), then relock the bootloader using the fastboot commands.

As we know, an Android phone is first controlled by the bootloader.
Only the bootloader can read/write the NandFlash, so, if the bootloader is locked, then flashing commands issued by fastboot will fail.
My question is:
If the bootloader is not unlockable by design, how to root a phone?
Hi, I awant to root my H901 by unlocking bootloader (V20J). However, my concern is can it be locked again as I will sell it after a month or so and I don't want any bootloader unlock alert at startup? Has anyone tried to relock? Plz let me know, thanks.

To relock the bootloader follow the following instructions:
Put your phone under the fastboot mode
enter the following commands: fastboot oem lock
Keep in mind that while your boot-loader is locked, you will not be able to root or flash ROMs to your phone.

Thanks. Yes I can unlock the bootloader again to gain root but I have read in unlock thread guide that relocking might have unknown results. Have you or anyone else tried relocking personally?

You should not re-lock you bootloader if you have root but if you are going to trade in your phone or sell it then you should definitely re-lock your bootloader after you flash a stock ROM.
Bump..... Anyone successfully relocked bootloader without any error and got rid of unlocked bootloader at startup?

I successfully locked bootloader, thanks.
So i have F700L. While unlocking developer mode i found the "enable oem unlock" meaning it will unlock the bootloader right? So can i root it and flash rom?
I'm not sure if its actually a proper unlock (Tmo has unlocked bootloader, but locked up fastboot). What I do know is that you probably won't get TWRP or any custom ROM because all of the ROMs here are made specifically for the RS998, H830, or H850.
I am thinking that to unlock lg h860 we can first flash lg g5 h850 rom in it and then we can unlock the bootloader bec i think hardware configration is same lg g5 so this method should work had anybody tried this??
I found this method below at the link posted to unlock the bootloader for the H860. Try this at your own risk, I have not tried it myself because I dont own the phone yet.

I doubt this will work, so far only European H850s have had the ability to unlock. It's not as simple as flashing a H850 rom either, that doesn't override the bootloader.
Flashing the whole rom (a KDZ rom or every img file from a complete zip, with all the complementary partitions, as the bootloader) could be in theory a solution. But you should be able to trick LGUP so that is sees your H860 as an H850, and then flash the ROM (hoping that the partition scheme is compatible). You should also make sure that the H850 bootloader can't detect it's being loaded on a H860 (refusing to boot), and only then you will be able to flash TWRP and do whatever you want on the phone.
Unfortunately, I don't know any way to circumvent these two obstacles.
Flashing just the bootloader using
Code:
fastboot flash bootloader bootloader.img
shouldn't work, as the bootloader is locked.
In my developer option I now see : Enable OEM unlock option. Does it mean my H860 is unlockable?
In theory yes, try enabling the option and unlocking the bootloader.
Dear Masters,
I bought a 2nd hand LG V60 V600VM from china taobao store and it comes with a customize firmware, i don't like it and flash it back to 30b (android 12) stock firmware using LGUP.
I would like an upgrade from android 12 to android 13 from Verizon OTA but fail, i found the problem should be the phone is still boot loader unlocked.
I search through the web can find many tutorials of how to unlocked boot loader, but can't find one teach how to re-lock the bootloader.
Can any experts shows how to do that? I just want my phone back to stock, everything back to stock, no need root, no need boot loader unlock....
Thanks very much!!!

It's the same as unlocking but when you get to the step fastboot oem unlock, do fastboot oem lock instead.
