[Q] How to relock bootloader to 'locked' not 'relocked'

Hi guys, i have a question, i want to return my phone for warranty and i've read this thread that if your bootloader is showing 'relocked' you cannot return the device for warranty.
I am here to ask if there is a way to make the bootloader show 'locked' bootloader instead of 'relocked'?
it would be GREATLY appreciated if you could help me. thanks!
for those who want to relock their bootloader can follow the instructions here

There is no way to do that ATM.
If the problem is the hardware issue, HTC should honor the warranty.

actually i'm looking to sell the phone, the phone have no issues whatsoever, but if the person i sell to wants to claim warranty, it may be an issue.

Not possible. When you got your unlock bin from HTC, it logged the device info. There gonna know right away it was tampered with.

so that means there is no option to claim warranty unless i pay for the 'fines' or charges that incur to repair my device?

Correct. From what I've read, unlocking voids the warranty instantly (even tho htcdev says it "could" void your warranty) So any repairs are gonna cost you.

OK.. while trying to re-flash my phone after messing up, I tried to re-lock (fastboot oem lock) and it put up 3 messages, 1 succeed, 2 failed, on reboot of phone it read locked.
Yes!! Locked not re-locked ! I forgot I had not flashed stock recovery ! So triued to unlock, it worked but I could not flash stock recovery, failed, but I could re-lock with same LOCKED message, if I then went from HBoot to Fastboot I got a new menu SECURITY .. bellow locked a message SECURITY WARNING, if I select SECURITY menu then I get a new screen , KEYCARD failed, and reboots.
Anyway the LOCKED was enough to get the phone swapped as its two weeks old, any way after charging and attempting RUU again it locked on black HTC screen most times it booted.
Still maybe this menu holds a key to S-OFF, and maybe the relock failing can be replicated, it seems to have sent only 1 of 3 parts if the file across, so if you phone is bricked maybe you can give it a shot for htc service cover by part re-locking in some way.

and was hoping we could make some headway on it.

I noticed you are on Vodafone Australia.
I spoke to multiple stores and service reps and each of them said the same thing, that merely unlocking the bootloader will not void your warranty with them assuming a hardware fault. They even allowing discussion of bootloader unlocking in their community forum.
They did say however that flashing custom roms and rooting will void your warranty as per usual and any damage caused as a result of overclocking or messing with voltages etc is not covered.
I don't know if that is any help, but they seem pretty good about it so long as you didnt cause any actual damage yourself

Unfortunately I bought it outright from All phones. Don't think they'll accept it. but never mind anymore, I sold my HTC one x. I put up a *phone has boot loader unlocked* note on the ad

[Q] Question: Rooting and Bootloader

I recently came across this article here: http://www.redmondpie.com/unlock-nearly-all-htc-bootloaders-while-sparing-your-warranty/
Basically, I can lock and unlock my bootloader at will
Warranty is voided if you unlock the bootloader, which is required for rooting, unless there's a method to do otherwise.
Is my warranty still available if I unlock, root, then relock? Because the HTC service staff says that unlocking might cause damage, but as far as I know none will be caused. But should it do so, won't relocking it make it alright?

Also came across this: http://www.modaco.com/topic/353986-...t-unlocking-the-bootloader-windows-mac-linux/

Rooting without unlocking bootloader is impossible.
Your warranty will be void if the bootloader has been once unlocked. Relocking won't always make it better and it will display **relocked** instead of **locked**
It's not impossible though to get the phone fixed under warranty with unlocked state...

Perhaps where you are from, it is permitted. Here though, the technicians tend not to know too much about this kind of thing.

I've seen all sorts of reports. Some with unlocked bootloader have success with warranty repairs and some do not.
It all depends on where you send it back, who looks at it, what the actual fault is and the position of the moon.
I seem to recall on htcdev and the screen on the phone when unlocking say 'may' void your warranty.
Basically pot luck but not 100% no.

Seeing as it's the same thread, I'd just like to ask if there is ANY damage caused at all by unlocking the bootloader. As far as I know it does not happen.

[Q]Unlocking bootloader, questions!

I'll make it short:
1. Since you have to provide your IMEI number on the sonymobile website, i guess that even if you relock your bootloader later, sony will know that you have already void your warranty and you will permanently lose your warranty. Is this correct?
2. Can "locked bootloader" roms be flashed on phone with unlock bootloader. I know it's a silly question but i didn't want to open a new thread for just one question
3. Any benefit of unlocking the bootloader over flashing roms with locked bootloader?
4. Is it worth playing with roms on this device at all, since jelly bean is just around the corner? I know that official firmware is always bad and that the custom ones are modified well. I'm fed up of the lag my phone has, every time i pull my notification bar...i'm on official firmware and i'm using build.prop tweaks but they're not helping much.

SONY Says unlocking Bootloader may void it's warranty.
Well see, this is how it works in my country. Upon unlocking bootloader i loose my warranty. But the warranty for any hardware damage is still valid here. Which means with a unlocked bootloader i will not get warranty if my phone gets bricked by any Custom ROM/MOD try out or Software related issue.
But let's say, the screen isn't working or the speaker isn't working, then i might get a replacement for this type of hardware damage. Only parts replacement.
But yes this may not same for all region. Or may be the SONY service center people here are little too kind
But yes, they can check the bootloader unlocking status easily, if i am not mistaken, cause one of the SONY Forum moderator told me so.
Lastly, Playing with the ROM actually Depends on you, some likes custom ROMS and some like Stock ROM.
But since the JB update is just doorstep ahead, so i would say, you wait for it. Do not unlock it now.

1. Yes they usually check but it depends on your country too. In my country I got my phone's screen replacement done within the warranty after unlocking my boot loader.
2. Yes you can flash any ROM for Xperia S.
3. Main advantage is that you can flash custom kernels ( even ROMs like Cm, slimbean etc.)
4. Absolutely. You can still enjoy official JB even after unlocking your boot loader.

Relock G6 Play bootloader

Ok, I tried about every method and every stock rom I found on the net in order to relock the bootloader for my XT1922-3. And whenever I try to lock or unlock the bootloader I get the message "invalid boot state" and the next line read "OKAY". The bootloader remains unlocked. Bootloader shows "flashing_unlocked". Please, can anybody help me? I really don't know what else to do.

There's no point in relocking it plain and simple that's why you haven't found anything about it. Even if you do relock it for the purposes of trying to trick Moto it literally tells them in the logcats it's been bootloader unlocked. Also once you request the key and use it it voids the warranty which Moto also knows about. If your trying to sell it just be honest and tell the person it's bootloader unlocked but it doesn't effect the phones performance

I was just worried that something has gone wrong while unlocking. Thanks for the reply!

It should be possible to re-lock it like this (connect to PC in (stock) recovery mode --> fastboot oem lock begin --> flash stock ROM --> fastboot oem lock).
Also according to Motorola.
However it doesn't work on my device (XT1922-3). It returns confirmation messages with no single error, but it seems to ignore the command as the bootloader is still unlocked and still allows flashing other ROMS. I haven't seen anyone who succeeded in re-locking their Moto G6, except this person, although the same method is used.
General info:
- Motorola claims that just requesting an unlock code already voids the warranty (boooh!), except for the so called "Developer Editions". This however is a false statement if you bought your device in Europe, even if your bootloader is unlocked and have a custom ROM installed (they are required to follow the EU directives which means they can only withdraw the warranty on this basis when they can proof that the damage is caused by the custom software). I don't know about other regions.
- When unlocking a Motorola-device, it will be permanently detectible that it has been unlocked, even if you re-lock it afterwards. I've read that they use eFuses for this (clearing a value (possibly outside the partitions) or in some cases physically burn a small fuse). For restoring an eFuse you would need to know its initial value and set it again (generally not possible through known interfaces like USB,...).

Motorola doesn't even provide stock images for the XT1922 on their unlock support page. I assume they simply don't want users to relock their devices

So, giving the person making that statement the benefit of the doubt, s/he probably didn't unlock an XT1922-3.

Yup, Motorola, help users void their warranties outside the EU by not letting them relock again. Way to go, guys and gals

What? Why would they let you "re do" your warranty, when they tell you it's void as soon as you request an unlock code ? You can do all manner of stupid crap to brick your phone with an unlocked bootloader.
It allows you to try to flash the wrong firmware, to downgrade sensitive partitions (bootloader, gpt, etc) which would bork security updates and all manner of crap as well as bricking.
And they should allow you to re-lock and indiscriminately let you just warranty and rma your stupid mistakes?
We all wish they would but...
You know the risk when you unlock. They clearly tell you on Motorola's web site, as well as all posts on XDA that show you how to unlock your bootloader.
And you think you got cheated somehow? Geez.
Follow their rules if you want your warranty. End of story.

Reality is that in 99%+ of the cases bricking a phone is done by dropping it in water or on hard surfaces,....

In reality mostly the opposit happens. Many users with stock ROM and locked bootloaders are exposed to potential security risks, because they're not getting updates anymore after a while, or none at all (Motorola = 2 years). An unlocked bootloader and optionally a custom ROM can solve this.

It's not a wish anymore where I live. Off course, as said before: in the case the custom software broke your phone, you cannot make use of your warranty. I don't think anyone disagreed on that?

Motorola smartphones are quite unique in this matter. My other phone didn't had a locked bootloader by default. I'm more secure with the latest Lineage OS than the older stock ROM. And this doesn't void warranty, even if bought in the US. Laptops/PCs all have unlocked bootloaders. Using custom software shouldn't void warranty. It's not so strange…

Yup, fortunately for us, here in the EU consumers still have rights. Motorola can put whatever they want in their policies, but these don't trump our rights. IMO it's a strange - even dangerous - statement that anyone needs to agree to the biddings of a private company to keep their warranty. This warranty is granted us by LAW. Why would anyone argue in the favour of a large private enterprise anyway? We need to be protected from them, not the other way around.

It's the same in the US. It falls under the Magnuson-Moss Warranty Act of 1975, which was ruled to apply to smart phones in 2015 by the FTC. We can run 3rd party software all day long and it doesn't void the warranty. You root and the headphone jack craps out? It's covered. You root, run an overclocked kernel and burn up the cpu? Then they'd have to prove that whatever you did, broke the phone in order to void the warranty. If they can't, they gotta replace it. They won't even look into it at that rate. It isn't worth the cost of litigation. It's cheaper to just send you a new one.

Question Xiaomi.EU - void warranty?

That is worth install that If I will purchase this phone and that is new?
void warranty? maybe If I locked the bootloader again on xiaomi eu that is okay?
Fast charging 33W works?

Firstly don't consider locking the bootloader once you've done any ROM modifications.
Secondly unlocking the bootloader doesn't actually void the warranty on a Xiaomi device so you should be fine. However it's up to the discretion of Xiaomi (i.e if you brick the device then that's your fault)

You have to check Xiaomi/Redmi/Poco warranty policy in your country yourself. The regulation varies between countries and regions.
In many countries and regions Xiaomi/Redmi/Poco still have warranty coverage after bootloader unlocked, but there's some exceptions. Check it yourself on the official website.

Relock bootloader with Xiaomi.eu ROM that was based on China ROM in your Global phone is dangerous.
You can try if you dare to risk it on your Poco F3. You have been warned.
The principle is: do not lock bootloader.

Flash stock ROM back into phone, which makes phone looks identical to just after bootloader unlocked, so it's can still be under warranty, if you were able to flash it back.
There are exceptions that will still void warranty, read the policy yourself.
