Bootloader relock

Is there an option to lock the bootloader again after unlock?? for warranty things

8don't know but I don't think it will work cause of custom boot image.

I don't know. I have flashed the v20a (leak version) and unlock its bootloader, then rollback to official v10e, and then flash the official v20a and the bootloader is already unlocked. I think its been unlock forever maybe????

Supposedly, you can flash a v10x firmware and it'll show as locked again, if I'm not mistaken. Although if they update your firmware back to a v20x, as they probably will, it will show as unlocked, and they might have a way to know when/how it was unlocked, and claim you had it unlocked before.
My advice (and personal intention) is, unless you're a developer, do not unlock the bootloader unless you're willing to risk voiding your warranty.
Although I'd be quite curious to know if they'd have the guts to invoke the unlocked bootloader for someone that goes in with stuff like dust between the screen and the Gorilla glass, or hardware failure of some sort.

AFAIK when you unlocking bootloader you actually write some data to a special memory called fuse. This can be done only once. Therefore it is not possible to be locked again. But it is possible to ruin the the fuse if you do something wrong and you lose forever possibility to unlock.

Well I was on leak v20a and unlock it and flashed cwm, then i flashed Official v20a .dz with lgflashtool and bootloader got locked again. I needed to unlock it again. You can try that.

I flashed between 20a leak , official 20a and 20b, and not once i had my bootloader relock by itself

With lgflashtool or kdz? Well I dont have any proof of it becouse I didnt expected it would happen. Anyway I flashed with LGflashtool without battery and sim and with 910kohm cable.
Edit: this will clear all your data and format internal sd

i flashed atleast once with lgflashtool (screwed something up after deleting some bloatware + installing wrong unsecure img or something, all in all i couldnt enter S/W at all), and several times with kdz (between 20a leak and other 20x's).
and all troughout this bootloader stayed unlocked (i am on eur-xxx, so i unlocked my bootloader the day the method was found, if i recall correctly)

It may be an isolated case. You never know with LG But i am sure it was locked again, even flashed cwm thinging it stayed unlocked then gave me security error when I tried to boot recovery. So i unlock it again. Mine is also eur-xxx.

Bootloader can't be relocked. When you flash kdz with all usual methods available for p880 you also flash secured bootloader and system recovery too. So you must flash these two again from adb every time you flash new kdz. Security error may appear if you don't flash unsecured BL before CWM.
Any way regarding warranty I don't think that LG service will bother to check bootloader state if device is bricked or something.

It can be relocked since mine was in fact relocked. It just that we need to find way. Unsecure boot.img has nothing to do with unlocking bootloader or properly running recovery. It just give you root access from adb. It is property in ramdisk in default.prop ro.secure=0. And they will sure check bootloader unlock status, they even developed Windows app for root checking.

I'm saying that secured bootloader won't load unsigned recovery. So maybe thats reason why you got security error. Anyway if you think unlocking is reversible maybe its best way to ask LG. Their FOSS section replied for unlocking process, maybe they answer you.

If the device is bricked, they'll need to find the problem before they solve it. They'll surely run diagnostics on it, and a phone diagnostic tool that doesn't diagnose something as basic as "has someone been messing with the bootloader?" isn't that good of a diagnostic tool at all..
So yeah, I'm pretty sure they'll check it. And even if I weren't, some LG support centers (the portuguese one being one of them) have mentioned that unlocking the bootloader will void your warranty, and the warranty itself mentions it (by saying any change to the provided hardware and software, which the bootloader is a part of, will void the warranty). So, at the very least, we should leave it as a warning to the community that their warranty might be voided when unlocking the bootloader and/or rooting their phone.

My point is that it is useless to try relock your phone.
I agree with you completely in everything you said about warranty. I think there should be warning about warranty. Also there still no need to unlock while we waiting for custom rom (CM).
Anyway I'm more than year on this forum and I never saw someone refused by LG service because their device is modded somehow.

from searching internet about someone bricked his phone with erase bootloader command i found 2 cases on Asus nexus 7 that they got replacement after they erased their bootloader - of course they didn't mention it lol

Yes, but Asus's policy wherever that person bought the Nexus 7 might be different that the policy for LG in our respective countries...

I borrow some text from a blog :
This is a joint blog post written together with Carlo Piana with the goal to disband some popular FUD that you lose your warranty if you flash or root your device.
Does rooting your device (e.g. an Android phone) and replacing its operating system with something else void your statutory warranty, if you are a consumer?
In short:
No.Just the fact that you modified or changed the software of your device, is not a sufficient reason to void your statutory warranty. As long as you have bought the device as a consumer in the European Union.

It clearly states that not only rooting but also flashing your device with a custom rom , can't be held responsible for the defect at a device.
A friend of mine had a faulty screen on his galaxy nexus and gave his device rooted , of course the store who sold the phone refused to repair it , but after being aware of this directive and to avoid further legal actions from the buyer's side, they agreed to repair the phone at no cost.
I relate this case to the thread for the guarantee part since an unlocked bootloader is needed to flash custom stuff to it and is part of the software imho.
This is the source text.

It's nice to know that directive. People speak of them having to fulfill the warranty if the root/unlocking isn't directly linked to the problem, but this gives us something to use in case they don't do it voluntarily.
Although, keep in mind that any problem you cause due to your rooting (e.g. deleting system files, freezing the wrong apps, etc.) or bootloader-unlocking (e.g. deleting your bootloader, incorrectly installing a ROM/kernel, etc.) will probably not be covered by warranty, as it was your action that caused the error.

Bootloader locked means u cannot load anything at boot that would tinker with the basic core of the device, like u cannot use custom kernels when ur bootloader is locked that is y ppl unlock their boot loaders Google for further info.
As for the OP's problem :
This is a known issue when u root ur device without unlocking bootloader, the solution to this is to do a full repair using Sony Suite which will result in loss of all data phone ,SD card etc .
check this link out its clearly stated over there
http://forum.xda-developers.com/showthread.php?t=2186368
Troubleshooting:
if your device has unlockable bootloader then after applying this hack the bootloader status will turn "Bootloader unlock allowed: No"
in that case dont worry the users have reported that doing a repair via SEUS will flash back stock firmware and turn this status to "Bootloader unlock allowed: Yes" (the same might also be achieved by flashing a stock FTF using FlashTool <yet to be confirmed>)
ROOT WILL BE LOST BY DOING THE ABOVE AND YOUR INTERNAL STORAGE MAY GET WIPED!
SO DO A BACKUP OF APPS & INTERNAL STORAGE ON AN EXTERNAL SDCARD/PC

How so some people can unlock the bootloader and some can't??

[Q] Factory locked bootloader

Just received the XSP as an upgrade on T-Mobile UK and was disappointed to discover via the service menu that the bootloader is unlockable. Forgive me for asking but does this mean that there is absolutely no chance that at any point in the future I will be able to unlock it? I would like to use custom roms and want to know if I kight as well look for a new phone. This was never a problem on my old Optimus Black.
Thanks in advance.

Praise the (Doom)Lord! Will this allow us to unlock the boot then andflash custom roms?

Just to make it clear bootloader is locked this means no custom kernel which might mean custom ROMs are out ie. Cm,akop,PAC etc
You will be able to root using doomlord exploit and in time will get cwm for locked bootloader so we be able to use modded stock ROMs.
As it stands only root is available for locked bootloader hope this helps

Great, thanks. This is exactly what I needed to know. Guess I'll have to be patient then..

There is a way to unlock your bootloader. You must get a SIM unlock code, unlock your SP and send an email to Sony with some data like Imei, unlock code, etc. Then a messenger will be sent to pick your phone and lucky, Sony will unlock your phone.

this may be true but it only works with bootloader that is allowed, he states in op that his bootloader is unlockable.

Few days ago sent an email to Sony asking about this issue. Here in Spain there was a global complaint from Xperia U users asking for open the possibility of unlock their bootloaders: not to unlock it but to change the "unlockable" state of the phone. After the debate, Sony says people could send their phones to Sony attaching the respective unlock code with which they'd unlocked (SIM Unlock). Then Sony would send the telephones with the bootloader unlockable.
PS: Maybe he meant "not unlockable" instead "unlockable". If it's unlockable then he doesn't have any problem!

Yeah, mate. You have to send a message to Sony saying you've (sim) unlocked your phone and you want to unlock your bootloader. They will send you all the information you need to go through with the process.

From what I've read is impossible because when you unlock the bootloader it burns some sort of fuse or something like that, which can't be recovered

If the fault with your phone is nothing to do with the bootloader your guarantee won't be affected.

you will loose guarantee either way as the bootloader will show as tempered. More chance to keep it valid if you use the tools HTC provided.
Orange should work just fine. Just try...
On another note i sent 2 phones for repair to HTC "unlocked" and they never charge me for the repair.

yes, i was thinking of only gettin root and not unlocking bootloader

You can undo the root and unlocked bootloader, before you send it to HTC. If you cannot undo because you have too big problems with the phone (frozzen phone,...) they cannot controll it either.
