[Q] What's the benefit of relocking the bootloader?

Curious.....and I didn't see a thread about why some folks do so

none. its the same thing, just have it relocked when u send it in for warranty purposes + on stock

Like zephiK said: none. There is absolutely zero benefit to relocking the bootloader. On the contrary, there are many disadvantages:
if you ever have to unlock again, it will wipe your data
you cannot use most fastboot commands, which means that, unless you have root, you cannot flash radios, ROMs, backup your data, etc...
People relock their bootloader because, in my opinion, they are not very knowledgeable about how Nexus devices work, and have it in their head that, to be fully stock and receive/install OTA updates, you need to have a locked bootloader. Certainly not the case.

There was a guy on here who wanted to return his phone back to stock for warranty. His USB was broken. He could return everything to stock through the phone, except for locking the bootloader. If it was already locked, the problem wouldn't be there...
Not a good enough reason for me, but it could be a factor in your decision...

I still don't know if I believe that Samsung will not honor the warranty because the bootloader is unlocked, particularly on a device with a re-lockable bootloader.
As we know, HTC honored the warranty on the Nexus One, even though with an unlocked bootloader.

it's not so much the OEM, its more of the carrier.
vzw will not honor anything if the bootloader is unlocked.

Like I said, it's not a factor for me. I unlocked with about 10 minutes of my first full charge, and don't see any value switching back. Everyone is different though, so I thought I would just share this detail, no matter how trivial...

Not really. You can flash a stock ROM and via ROM Manager - you just can't lock the bootloader...

thank you very much

Most likely yes, however we cannot guarantee anything. If you send your phone to official Sony Center and they do thorough checks, it can be still seen, if it was ever unlocked or not.
I had an issue with my phone's screen, a beta-stage ROM f**ked it up. Relocked bootloader, full stock firmware and they did not find anything. They changed the display and all good now.

[Q] Getting Htc one x ready for warranty

Hey guys!
Ok, here's the case, I'm having troubles with my HOX, probably it's lcd or motherboard, the phone's screen won't wake up most of the time, and you can feel vibration while touching the screen which means it's working and you just can't see it.
I'm preparing the phone to send it back to warranty, flashing back the stock recovery, relocking the bootloader and flashing original firmware (downloading as we speak). The thing is, I'm quite worried the warranty will be void due the re-locked status in the bootloader and I'm wondering is it possible to get it to say locked again or is it possible to somehow intentionally brick the phone so they can't even get to see it was rooted and unlocked?
Any suggestion will be highly appriciated

I don't think it's possible to make it appear locked again. But when my HOX died I just handed it back in.
Nothing helpful but just sharing my experience.

My colleague had problem with screen - with wake up. And when service saw relocked they told that it's related to the unlocked bootlader and installation of other software.... Warranty not void....

I've had numberous e-mails with HTC staff via htc.com and they told me that they warranty is NOT void by unlocking the bootloader or flashing a custom rom. it IS void if you do something wrong and brick the device.
Although, If I were you i'd still return to stock.

What is the best way to root G4, whilst keeping it "friendly" for warranty claims?!?

Hi, forgive me if this thread isn't in the appropriate section.
I have a bit of rooting experience, haven't done much in a few years though, (knowing that there are now several ways to root devices), and have just picked up the G4.
Now I'd like to root the G4, but keep the stock rom, (6.0) and mainly will be just running xposed to edit and muck around with LG's ugly skin. I'd still like to be able to receive OTA updates, (even if the OTA update may remove my root,) as well as hopefully still be fine if I needed to return the device under warren.
I've been reading around and apparently you must unlock the bootloader in order to root for Marshmallow? If i were to still do this, could I keep the stock recovery at least, or if not, would I be able to easily revert to stock with a stock recovery and relock the bootloader?
Apologies for my ignorance, just trying to figure out if I should really be rooting or just chuck on Nova launcher and be happy with LG's offerings. Cheers

Keep it on a stock rom and if yoi have a carrier varient then try to not change the boot logo lol idk just a guess.

Yes to reflashing stock rom
Yes to relocking the bootloader
So you are clear to make whatever modifications you want, you can always revert safely.

Once your bootloader is unlocked, you cannot relock it. Your device will always show a message saying "Bootloader unlocked" after turned on. Warranty is likely to be declined then. BTW: You have to get your unlock.bin file from lg, agreeing to void your warranty. So, even if you smash your screen and they cannot see the message, lg knows it is out of warranty.

Since when do you have to get the unlock.bin? We unlock from fastboot. Have you confirmed by trying to relock from fastboot? I read otherwise from another thread.
Furthermore, a quick search around indicates people who have unlocked and rooted have had their warranty honored despite software changes.

Unlock from fastboot is only possible after flashing said unlock.bin file, which can only be obtained by lg and is unique for each device. Furthermore, I had an unlocked, bootlooping h815 and lg refused warranty to me (in Germany). Got my phone replaced by my vendor on eu law which only applies if the defect strikes in the first six months.
So, while some people are lucky to have their phone repaired despite an unlocked bootloader, I'm really happy for them, but lg is not bound to repair it on warranty

Ah I see. You have a h815. I have a h811. Our process differs there.

Hmmm, thanks for the info guys. Its not from a carrier, i bought it outright. Seems like i might just have to keep it stock, its not too bad as is, guess ill just have to live with it. Thanks for the help though.

At least you can root with locked bootloader

Not under marshmallow

You can do none of things you listed keeping it stock. First of all google change policy and in marshmallow you need to flash modified boot.img in order to flash custom recovery and/or to root it. As you know the bootloader has to be unlocked but there is no way to relock it. So sorry, but impossible.

People need to understand a simple thing.
You either mod your device and lose warranty or you keep it stock.
It's that simple. People worried about warranties and ota updates are on the wrong site.

Get Warranty back again

Hi guys,
I'm using Gingko MIUI11 official with Bootloader unlocked and rooted, also Orange fox installed. As per invoice my device is still under warranty. But as I've unlocked bootloader, give root access also using a custom recovery what should I make sure before visit Service Center. As I'm facing proximity sensor issue and I've troubleshoot and found its hardware issue. So before visiting service center do I need to clean flash official MIUI again, lock bootloader again? Any suggestion please. As its my primary device I just don't want to clean flash. Is there anyway or advice? Or there is nothing to do
Regards

The only way to get back under warranty is to clean flash and relock bootloader

ok i misunderstood, that's what i read
, "Our ROMs were approved by official EU distributor ABC Data to not void warranty for devices sold by them! (Of course, officially unlocked BL and no ROOT installed)"

i remember xiaomi india tweeted : Unlocking bootloader does not breaks warranty

no you cant claim warranty,
you already given root access to RN8,
unlocking dont void warranty but root will surely end warranty

don't try to lock bootloader, you'll brick your device,
just unroot and claim warranty

Ok sorry for so late... I've visited to my nearest Service center and repaired my device and Rooting or Unlocking bootloader doesn't void warranty said by the Xaiomi Service Center. Thanks to all
