If I lock the bootloader is the warranty still ruined? - Redmi Note 8 Pro Questions & Answers

I am planning to root my device and I was wondering is the warranty still ruined after locking the bootloader so my question is:
If I lock the bootloader is the warranty still ruined?

Well you don't lose it in the first place. No, unlocking the bootloader doesn't void your warranty.

if you restore MIUI rom and bring back phone to factory system you not loose your warranty, only if you leave unlocked bootloader and custom rom in phone you dont have warrant.

I believe once you unlock bootlaoder service center can check if you did it or not even if you re-lock it.

No, if you reflash the firmware, they can't check if you've unlocked it before (if you didn't unlocked officially in the first place).
Well most manufacturers (cheepo ones) do not implemented this kind of tech that persists data over a firmware flash.
Also, most of the time, they don't even check for this.

[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...

[Q] Does flashing 'universal' (unlocked) stock ROM void my warranty?

Hey guys,
I'm sorry if this has been asked before - I did a search around but found nothing, surprisingly. Question is, if I flash my HTC One X (which is currently stock and on a plan with Vodafone, so full of 'bloatware' and 'outdated' builds) with the 'universal' (unlocked?) stock ROM will my original warranty be voided? My main reasons for wanting to do this is remove a few unnecessary apps that Vodafone include and make sure I'm receiving the latest OTA updates straight from HTC. Obviously I can continue to wait for the updates and turn a blind eye to the 'crapware', but if I'm able to flash the official stock ROM straight from HTC then I'd much rather do that, just need to make sure no warranty issues will arise as I'd hate to have such a beautiful device collecting dust because I was too impatient or ignorant to check beforehand.
Thanks for any suggestions or help,
DJ GLiTCH

If you are going to flash any ROM (including stock) you will need to unlock your bootloader first (via HTC dev) and install CWM Recovery. The act of unlocking you bootloader voids your warranty. They keep a note of all of the phones that they have unlocked. You may still be covered for physical defects (although maybe not) and you definitely won't be covered for anything software related.

Not technically true.
HTC clearly state that unlocking your bootloader *may* void *certain* parts of your warranty. In other words if you screw up your phone as a result of flashing roms then your on your own. If your phone develops a fault then it's covered.
HTC can't possibly keep a note of what phones have been unlocked. How can they? When you go through HTCDev.com you get sent the unlock file which you then have to flash. Only because HTC sent you this file it does not mean that you have flashed it - you may have changed your mind afterwards.
Once you unlock your bootloader and flash a custom rom you can choose you revert back to Stock by relocking then flashing the Vodafone branded RUU file. Providing you don't balls up your phone during this process your entire warranty will remain intact, including software issues.

If you unlock and afterwards relock the bootloader again, in fastboot mode it says bootloader RELOCKED and not LOCKED. That`s how they see it.
I spoke to Vodafone Australia and they assured me that the act of unlocking alone does NOT void your warranty, however once you make a modification, warranty is gone. So yes, flashing another Rom will void warranty

Actually, as pointed out by Gee2012 above, the bootloader says Relocked if you lock it again - so it is fairly obvious. This is irrelevant anyway as they have your phone imei number which is most probably what they use - they aren't stupid!
And from what I have been reading - HTC are being funny when people are trying to claim on warranty even if it is a physical defect that you have, once you have unlocked your bootloader. See here:

Yes I know it says relocked but HTC arnt keeping a "note" as such at the point of unlocking via HTCDev.
I sent my HOX back due to dust under the screen with the bootloader relocked and I received it back good as new (still unlocked).

They gave your phone back due to a hardware issue - fair enough. But if you went back for example with poor signal quality, even if you have flashed your original RUU, I very much doubt they would consider that under warranty anymore. They know you have unlocked the bootloader and tinkered with the software (even tho you are now back on stock). Have a lock at the link that i posted - it seems to be pretty murky water!
I also think that it also varies from servicecenter to servicecenter how they cope with this procedure or protocol. Some are more strict than others. I once took a bricked I9000 (due to a bad flash) to Dynafix and they repaired it under warranty!
It was running a custom rom and kerrnel.
Thank you all very much for your responses. I'm sorry for the delay, but for some reason never received any email notifications of replies.
I understand that flashing 'may' void warranty, depending on how far you go with the whole unlocking the bootloader and custom roms, but my concern is with flashing a non-carrier orientated stock rom. Such that I can revive updates quickly and OTA without needing the delay of Vodafone and the like, as well as removing all of their 'useful apps' they include inside their roms which I cannot remove.
Not trying to go off topic here either, but I come from a Samsung background (upgraded from the original Galaxy S) and was just wondering if the flashing process is similar? Like I'm guessing there is no odin for HTC, but clockwork mod and the rest are still around, correct? Not after instructions, just curious, as I'm trying to avoid losing my warranty and would likely only flash stock roms (for the time being at least, until I cave in). Cheers.
According to Vodafone, you will lose your warranty regardless of what you flash whether its stock based or not. They also said that simply rooting voids it as well.
However you might be able to flash the stock RUU for voda which may cover your tracks. I'm not 100% though.
As for flashing, Im still stock at the moment but from what I gather it is the same with respect to clockworkmod recovery and what not. But just double check any OPs before you start though lol

[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

[Q] re-locked bootloader warranty

Hello
I have unlocked my xperia arc s bootloader an my warranty was void

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.

Will unlocking the bootloader void my warranty?

Hi! I Just got the A2 Lite and would like to try some ROMs on It.
Will unlocking the bootloader void my warranty?
And if yes, Will re locking It get my warranty back?
Thanks in Advance
Unlocking the bootloader supposedly voids your warranty, but AndroidOne devices have no protection like Knox (which trips if you unlock BL), so there's no way of knowing if it's been unlocked before. Just flash the stock firmware via MiFlash and lock your bootloader before sending your device to warranty, voila. None of the roms I've tried work as good as the stock one though, I'd suggest rooting instead of changing the ROM. Have a nice day.
