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.

Done! it works fine, the boot loader is locked now, thank you very much!!!

You will re-lock the phone by flashing the SBF. To unlock reflash the unlock file..you'll still be on the latest SBF.
I unlocked my bootloader by going into fastboot and typing fastboot oem unlock, then it asked my to type it with my device id, so i copied the device id so i typed fastboot oem unlock ******** and it worked, it says unlocked and works

hi to everyone,
'till last week I was able to install every custom rom I wanted to on my mediapad, but now, after reinstalling an original one, my bootload is locked!?!
How can it be?
Fastboot says my lovely brick is LOCKED.
Is there a way to unlock it?
How?
Thanx in advance.

Just flash older fw version from huawei website. Last 2 or 3 versions are with locked bootloader.
This might work:
fastboot oem unlock
Why would they start locking the bootloader?? Locked bootloaders cause bricked phones

try to flash official c232b005. that is the last stable official rom that not lock the bootloader.
huawei starting to lock the bootloader from the released rom after that, for device s7-302u. maybe they think with locked bootloader user cant or difficult to root or anything else with the device. that can minimize the device brick.
I'm not sure what you guys know about the LG G Stylo (Cricket) scene, but here's a few things about this phone that you should know:
• no fastboot (bootloader) mode
• locked bootloader
• rootable on 5.1.1 (I'm already rooted)
• OEM unlock switch in developer options
• stock recovery sucks (basic, only able to factory reset)
All I want to do is unlock my bootloader, but as I've stated there is no fastboot mode. Sadly, I have no clue what to do about this. I have already successfully rooted my phone using KingRoot, softbricked the phone, flashed the KDZ, and rooted again, so I have a little experience with the software of this phone.
As I've also stated, the Cricket variant (CMDA/GSM) has a locked bootloader AND the OEM switch, so here's what I'm truly asking:
Is there any way that I can write my own fastboot/bootloader mode and flash it via Flashify? If this is indeed possible, I know for a fact that I can unlock the bootloader of this phone and flash a custom TWRP image onto it, helping tens of thousands of people with the same problem. I really love this phone, but I hate being locked down like this, especially with no good recovery to be able to flash a custom ROM if I had to.
If anyone has any ideas, please speak up!

It sure is, but you will need to reflash the stock rom and bootloader for your phone. Firstly you will need to find the correct kdz for you device, or use Lg bridge/ LG UP to get back to stock.
Once you have done that you can relock your device in fastboot mode using "fastboot oem lock" heres a link on how to relock just in case your not sure

Let me know if i can help anymore, ill try my best
Please excuse any spelling mistakes send for my LG G5
Just for info: fastboot oem lock worked also for me with latest nougat.. Thats what i did actually... No need to go back
Can confirm, "fastboot oem lock" works.
Sorry for reviving the topic (I hate it) But this model needs some updates. Hope I can help someone. This model is defective....
I was looking on the internet and everyone says to downgrade to v10c to lock oem back on G5 H850.
Well, I tried to do it with LG UP, got an error, and got stuck on Download Mode (Firmare Update screen).
I opened the LG Bridge, went to Software Update screen and them clicked on Recover Faulty Updates.
Then it worked and flashed the V20a-EUR-XX, Android 7.0 Nougat.
Went to fastboot mode, typed fastboot oem lock, and everything went to initial state... :good:
So I confirm that works on the last update (until now) V20a.
Can I relock with v20d ???
I relocked with V20a so you would assume so

No.
Just gone back to stock oreo and relock working with V30f-EUR-XX.
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.
