Re lock Lg G4 bootloader - G4 Q&A, Help & Troubleshooting

Hi everyone,
Previously on a Nexus 5, I bought a LG G4, everything fine, but I love to tweak my phone.
So I want to know if it's possible to re lock the bootloader when you unlock it with the LG g4 guide on official web site.
I know unlocking bootloader avoid guarantee and everything, but relocking it can put the guarantee back, am I right?
On my old Galaxy S3, it was possible to return everything to stock, bootloader, counter of flash and everything.
Thanks for your help.

It's not possible, yet.
A user claimed to be able to relock the bootloader, but his account was closed, since he was tampering with the imei.

Vodafone Carrier / H815 unlock?

Hi Im new in the "scene" of android dev. Got a brand new LG G4 (H815) with Vodafone Germany carrier. I´ve got root on my LG and want to go the next step to unlock my phone. So I followed the official LG Unlock Thread and have all informations that I need to paste in the unlock fields. But that´s what the dev page from LG says...
Unfortunately, your device(Germany,(VODAFONE(GERMANY))does not support unlocking the bootloader.
So I have to wait for an option to "hack" it?
/Edit I´ve called the vodafone support and they said that the phone is not locked... is their a difference between sim and bootlock?
Another question, is it possible to flash an open kdz instead of the vodafone one? and when which?
Bootloader is locked... There is no plan to unlock the bootloader... You can root your phone by using the low effort root for h815... Hopefully some of the devs is able to unlock the bootloader...

Yes, SIM unlock means you can use any carrier SIM card in the phone. Bootloader unlock is completely different. Our bootloader is locked.
If you wanr root, use this thread: http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
The international files work for your device.

I'm new to LG G4 thread. And i want to know about this phone.

Hi everyone, im just new user. My last phone was OnePlus One, before that i used Nexus phones. I wanna know wether if i flash and install any custom rom after unlocking the bootloader. Do you think i can get back to stock at the time of Warranty claim using some software or flashing some zip such way which is present in some forum just like OnePlus one, Nexus etc.

No, after you unlock the bootloader, you have lost your warranty. As opposed to Nexus, the bootloader cannot be relocked.

Bootloader Re-lock

Hey friends.
I'd like to know if there is any way (safe way) to re-lock the bootloader.
Thanks!
as of right now. there is no way to lock the bootloader. its been said many many times with lots of threads on the matter. only thing you can do is try hiding that you unlocked it by flashing a black splash screen.
not trying to be mean, but use the search feature...
I've heard using this guide re-locks your bootloader, but I can't confirm it since I don't have a ZE550ML/ZE551ML variant. Also, do it at your own risk:

So there's no way to lock ? bootloader again???

that thread is the most popular for people trying to find ways top re-lock it. right now the best we can do it hide that we unlocked it(all this is assuming you didnt use the official asus unlock tool, as the official one sens your imei to asus so they know you voided your warranty)

LG G4 H815 International Bootloader, OneClickRoot, Root, other Q's

Hi Everyone;
I have a few questions:
I am trying to unlock the bootloader for my nephews LG G4 but it seems like there is no way of doing it.
I followed the official method, entered the IMEI number and the DEVICE ID but I get a warning that they do not match and that we have X tries remaining before device gets locked. Right now it's sitting at 7 more tries remaining.
He had the bootloop issue a few months ago (phone wasn't unlocked or rooted or anything), sent it to LG, they fixed it and sent it back. The only explanation I can find is that the DEVICE ID doesn't match the IMEI number anymore because of them changing hardware? I really don't understand why the official method doesn't work or keeps saying that Device ID does not match your PHONE!
Anyway, I tried to root without unlocking the bootloader, and that didn't work either.
Is there a way to unlock this damn device without the official method?
If there isn't... Does using the One-Click-Root method work with this phone? He doesn't want to pay $80 AUD not knowing whether or not it will work...
Also all of this, just to fix the GPS Locking problem that HOPEFULLY would work if we change ROMS. Is there a way to fix the GPS problem without unlocking, rooting, and changing ROMS?
Send mail to LG about yours problem, they will send unlock bin
I had the same problem

Question POCO F3 Warranty

If I use ADB to remove bloatware on the F3, will I lose my warranty? Is the Xiaomi ADB official (from Xiaomi)? Do I also lose my warranty if I unlock the bootloader and install a custom ROM? If not does Xiaomi say so on their website? What is the difference between using ADB and just deleting them manually? Thanks!
You will not use your warranty by using adb to remove bloatware. However you do waver your warranty by unlocking the bootloader to put a custom ROM on it. However you can theoretically still get a replacement despite this wavering of a warranty

Thanks! What do you mean theoretically? Can I just install MIUI again and lock the bootloader and sent it for warranty, without them finding out that I unlocked it?

You should be find. I have never had a Xiaomi and so didn't know how supportive they are. The official advice by Xiaomi is here:
What do you need to know about unlocking?
First and foremost you can only unlock your own device. This means the unlocking tool you downloaded must be logged in with the same Mi account on your device. One Mi account could only unlock one device within 30 days
Isn't locking bootloader against Mi's 'geek' spirit?
Locking bootloader is aimed to provide a better user experience, which we've been trying to do the whole time. In the meantime, we've provided an unlocking tool for senior users who know their ways around flashing and tweaking their devices.
The unlocking procedure will need Internet access to get the unlocking password. Also, the Mi Account logged in on the Mi phone and the unlocking tool needs to be the same. Otherwise, the unlocking request will be denied. This will ensure that ill-intentioned people will not get access to your personal data.

And that's where I come in.
I sent my Xiaomi Mi 9T Pro as a guarantee having had the precotion of flashing the global rom and re-locking the bootloader (I had a problem with my antenna, I received nothing).
They supported my Mi 9T Pro without any problem
