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.

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.
Dear all,
Just as you might already know, not all Xperia Z are blessed with having an unlocked bootloader .... it apparently is something related to the carrier though and not to Sony themselves. As it happens if your bootloader is locked and is NOT unlockable you can still head to the website and get your unlock code by putting in your IMEI.
Now that's weird ...... Now just wondering if the same procedure could be applied to get the device bootloader unlocked ....

Yes true but then again why does the Sony bootloader unlock site still provide an unlock code for locked bootloader xperia z's? This implies that the unlock code is used by Sony technicians to unlock bootloaders ... it's only a matter of determining what that procedure is .... This is definitely being used by carriers.
Really interested to know this for certain, I just got a Z on o2 UK and am a little disappointed that I can't flash any roms. I don't think I can live with stock for ever! Had previously purchased a (dreadful) bootloader locked xperia play which had the 'bootloader allow unlock' set to 'no' which a helpful guy on here managed to change to a 'yes' for the reasonable sum of £10 but this was using testpoint method which obviously won't work on a Z as it's sealed.
If the answer is definately a no to unlocking the bootloader even 'unofficially' then I think i'll have to send this phone back and try my luck with a different phone (an ugly S4 probably). I really do love this phone but I also love being able to change my roms as often as I like to whatever I like.
In the past a bounty would have attracted some devs to work out a cunning plan but if this is not possible at all then theres no point
Anyone know for sure?
Maybe if you change your customization and download a generic cust. ROM, you could probably unlock the bootloader?
If you backup you data and create an ftf for your current cust, you should be able to restore if it doesn't work.
Use the first guide to get an ftf of your stock ROM.
Second to check what generic customization you'd like to download.
Third to change your customization and download & get the appropriate ftf.
Flash the ftf using flashtool.

The unlock code is generated from the imei number I think, so putting in any imei number will return an unlock code.

Well, it was a suggestion, you can try it if you want to.
If it doesn't work, then the only possible way is to somehow flash a bootloader that allows itself to be unlocked and this, I suppose, will require bypassing security.
The bootloader is usually not flashable and flashing an unsigned bootloader is even harder.
Reverse engineering bootloaders requires experience and involves a considerable amount of risk.
And that's only half the struggle. You also need to think about how you're going to flash it onto your phone.

I really would but I haggled a good deal with o2, £12 a month cheaper than what phones4u advertised with a free Z.
I am probably going to send it back though, just a shame as I really like this phone! Could always try phones4u and see if they will offer the same deal. I should have really thought about the possibility of permanently locked bootloader before I ordered it, after all the grief I had with my old xperia play.
So it definately can't be changed ever if it's set to disallow bootloader unlock?

So can no devs lend a hand to this issue. A lot of people with Xperia Z's are affected by this issue.
It's all down to the TA partition. If it contains "bootloader unlock allowed = no" then you are screwed. Trying to modify it or flash someone else's TA results in an unrecoverable, permanent HARDBRICK, regardless of what bootloader or kernel is flashed

I would like to point out something. Now I know these two things aren't the same, but I'd like to use it as an example. The Xperia Z's bootloader is locked, obviously lol, I've been modding xboxs and ps3s for a long time, and from that experience I think it can relate to this. Why? Well, from my experiance,on the xbox you can't put a custom dashboard unless you JTAG it, although you can get free games if you flash the chip on the disc drive but that's all. with saying that, it's like saying, you can put custom funcions in the Z but you can't change the ROM. So with the xbox, before you're allowed to flash a custom dashboard, you have to unlock your NAND software, with a ps3 (made by sony lol) you can flash a custom firmware if your on firmware 3.55 but if you're above that, you need an e3 flasher to flash your NOR or NAND chip to downgrade and mod it, one time with the ps3 there was a thing called a E3 Stick, I believe it was called that, i can't remember, and with the e3 stick it wpuld exploit the system cause it was a certain type of board it was build with... So if we'd be able to maybe, find a way to exploit the bootloader, or possibly JTAG it or flash it then I think we'd be able to achieve our goal of putting a custom ROM. The problem with the JTAG or flash theory is that we'd have to open the Xperia Z, so as another theory now, we find a device that we plug into the phone and exploits it to let us flash any ROM we want. just like samsung devices, if the phone gets hard bricked and it doesn't turn on anymore,fried, or if you want to reset the flash count you'd use a JIG to put it into download mode and flash any ROM you want to save the device.

Morning Friends,
I need to take my Z to a service center.
Now, I have a custom recovery (CWM Based), bootloader is unlocked, and a deodexed and rooted 434 firmware installed.
From what I know, the bootloader is not a problem - Just relock it with Flash tool. The recovery is what I'm worried about.
If I reflash my region's 434 Stock ROM, will it override my Recovery (and therefor Custom Kernel)? I need to leave no traces behind and as far as I know, there's no way to just uninstall a custom recovery as they're fused with the Kernel.
Ftf will restore everything

If you have a hardware fault then they should honour the warranty regardless of bootloader status
Yup, there's a small rip that I didn't cause in the rubber of the headphones flap, so it keeps popping open by itself.
Nevertheless, I wouldn't like to take any chances in case they decide to check the software on the phone.

Well, thing is, this is a Sony certified retailer I'm talking about - Of course they have their set of clear instructions from Sony, but they might slack off a bit - Or like Michealtbh said, might take care of it with or without any connection to the Bootloader.
Worth a shot.

No RUU is needed unless you've installed a custom ROM as well. Either use the RUU or restore from a stock nandroid for your CID, then flash the stock recovery, and lock it with revone

It's not risky as long as you follow the directions. Just use the RUU and it will overwrite everything. You still have to change the bootloader status with revone or something.

Actually it was a pretty easy process by following the following guide and some xda posts http://www.htc1guru.com/guides/return-stock-guide/
It really depends what's wrong with your phone. Unlocking your bootloader does NOT automatically void your warranty. I don't understand how that paranoia was allowed to spread so quickly and so far. I once took an HD2 back to T-Mobile running ANDROID on it. The guy just said "that's awesome" and sent it in for warranty repair. I got it back with winmo again but still. Point is you should really just go ask. If all else fails THEN you can go through all the relocking and returning to stock steps...
And before we get all the usual responses of "warranty says.."" when you unlock it it says..." And so on and so on, warranties are made to protect the consumer, you. Not the manufacturer/carrier. Unless something you flashed on it specifically broke it. They have to honor the warranty.
Hey, does anyone here know that if I root mybz1 and I notice somekind of problems in hardware or something. Ofcourse my warranty is voided since I rooted my phone, but if I unroot, will there be any kind of "fingerprint" of root or will I be clear with simple unrooting? I heard that samsung had somekind of counter that is unable to reset etc. So the ppl who repair phones will see that you have rooted it even you unrooted it. So long story short, if I unroot my phone will it bring back the warranty?
Sent from my C6903 using XDA Free mobile app
Rooting does not void warranty, only unlocking the bootloader does.
To unroot just flash a Stock FTF, there is no sign of root after you do this.
