Questions About Bootloader Unlocking? - G4 Q&A, Help & Troubleshooting

Hi everyone!
I bought an LG G4 really cheap on Saturday and was wondering about unlocking the bootloader. Coming from a OnePlus One with CyanogenMod 13, i have found the G4 quite difficult to adjust to with LG's rubbishy reskinned version of Marshmallow. It would be cool to install CM13 instead and have TWRP recovery on here as well, but i'm a bit worried about the bootloader because unlocking it is supposed to void the warranty. On the OnePlus One, the bootloader was of course locked by default, however unlocking it did not affect the warranty of the device.
If i proceeded with my plans of unlocking the G4's bootloader, what would happen to the device which would indicate to someone in the shop or at LG that it had been tampered with? And if it does leave evidence behind, is it possible to conceal this by relocking the bootloader?
I'm not too sure what the law on it in the UK would be, i thought someone said that if the bootloader unlock had no relevance to any fault with the device, then legally they'd still have to repair it under warranty. It might be different in the US.
Anyone know about this subject in more detail?
Thanks!

hi !
sorry.....but yes !
if you unlock your bootloader ,it's really true that your warranty (and all sorts of theses services) is REALLY voud !!!
strict rules by LG ! it's theirs laws ...
no way for relock this bootloader too !!! if you see a solution :it's false ! it's a big joke ...
if you decide to unlock it : it's your own choise ! your money ... the phone will go to garbage ,trash....in case of problem
That's why too many people don't want to unlock it ....and wait a solution for to root with MM ! if someone of developpers really search a solution...
cm13 is still in "test" at the begining ! go for 1 new years of devellopment with many periodics buggs ,with lots of adds merged and revert...... after cm11 and 12.1 ! lol ! and with poor camera ....etc...

Thanks for the response. Damn, that's a nuisance, so it looks like i'll be stuck without root or any custom ROM's for the moment. I do see what you're saying so i'll perhaps resist unlocking the bootloader for a while yet. Hopefully a root solution for Marshmallow will arrive soon, in the meantime all we can do is wait.

yes....
As far as i'm concerned ,i'm with LP rooted , waiting an eventual solution for MM too ...
i don't know if someone look for that ..... but generally ,for unlock a bootloader unofficially ,there are many "energy" everywhere !!!
And no news about Chainfire and others bigs hackers......

In my case i didn't void the warranty. Here in Italy l, at least.
I bought my G4 a couple of weeks ago and I unlocked the bootloader and rooted from day one. After a few hours of testing, the camera simply died... Factory reset, flashed new stock rom, custom rom... nothing worked so, bottom line, it was a hardware issue. I said to myself "there goes my money". After a couple of days I decided to go to the store and see how much it will cost me to repair it, giving the fact that I unlocked the bootloader and I was 100% sure that I've voided the warranty. The guy from the store quickly recognizes me and ask what the problem was. I said that the camera "dieded" and I need to know how much it will cost the repair because the bootloader is unlocked. Now, he explained to me that the problem with the bootloader is that you won't void the warranty if it isn't a software related problem. Only problem was that if you have a hardware related problem, they will FIX your phone for free, NOT REPLACE IT. So, after 4-5 days they sent my phone back 100% functional without any fees.
Remember that I bought my phone from an LG Store and i think that their policies should be the same everywere, correct me if I'm wrong. Now, i don't want to give false hopes to anyone and start to scream everywhere "HEY, UNLOCK THE BOOTLOADER, YOU WON'T VOID THE WARRANTY"... no, i will not say this things but this is what i've experienced and i don't have any reasons to lie.
Cheers!

strange ... i'm very curious to see LG rules texts exactly ... becayse it seem that they have said things like "if you unlock devise,in case of problems ,it's completely useless to contact LG for warranty ,it's lost ! " ==> that's what we have to understand ...

Yes, it is strange. Before i decided to buy g4 i read a lot about bootloader unlock and root, and i was 100% sure that unlocking i will lose warranty. I really don't know what to believe either. Maybe LG stores policies are different from store to store, country to country?

I'm in the UK and when unlocking bootloader it clearly states many times on lg website that warranty is void on BL unlock maybe it depends who you deal with in the store

[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

Help with getting HTC ONE X back to stock for RMA (hboot relocked issue)

Hello all.
I have an international version of HTC ONE X with less than a year which is plenty of faulty issues:
1. Wifi signal is extremely low and inestable
2. Screen goes crazy from time to time without pressing or doing anything
3. Three inferior buttons do not respond at all
So the phone is now pretty much useless (I have to power off and on each time I enter an app). The two first issues appeared at the very first month of the purchase, although I could live with them, more or less. The third disfunction has left the phone completely useless, and I had to buy a substitution one as I need it for my job.
I tried to swap the original rom with some CM and MIUI ones, trying to at least solve the 3rd issue so I had to unlock the bootloader via HTCDev (big mistake). I tried everything on my hand (except for opening physically the phone), until I took the path of the warranty service to get it repaired by HTC, as it presents the above-mentioned hardware-based issues.
So I relocked the bootloader, flashed back the stock RUU it came with, and updated it to the latest official one (4.2.2 if I remember correctly)
Now they have returned it (at no cost) and claimed that the warranty is void as on XX-YY-ZZZZ the bootloader was unlocked (they must have seen the ***UNLOCKED*** string on the bootloader and they got the exact date from the log I guess).
So, is there any way to get it back to ***LOCKED*** and "erase the logs" so they cannot tell if the bootloader has been unlocked?
I know it is only my fault, I should not have tried to fix it by myself and sent it directly to RMA, but I feel impotent that I cannot prove that all the faults are hardware-based, and the phone is pretty much useless long before unlocking the bootloader, which I did in good faith to try to repair it by myself without bothering the RMA service. Now they rely on this software-based feature to void the warranty and charge me for a, I guess, extremely expensive reparation (as both the motherboard and screen may need to be replaced to solve all the faulty issues the phone had from the very first month).
Thanks a lot in advance and sorry for the wall of text.
No not possible to get it back to LOCKED. The only thing you can do is RELOCK it.
Thanks for your quick response, Mr Hofs.
I have it ***RELOCKED*** and they have retrieved through some log that the bootloader has been unlocked (and the exact date).
So now, from lost to the river. As the reparation may cost several hundreds of euros (as they would have to change both motherboard and display to solve all the issues) and nobody can assure that the phone will be repaired correctly with all the flaws it has at the moment (besides, I have already had lots of bad experiences with the HTC RMA)....
Is there any way to extract, hex edit, and reflash via fastboot some critical file so it bricks completely the phone and no boot would be possible? That way they could not see the relocked string in the bootloader, or get any info from it. So I would send them a "dead" phone in the first year of warranty period (here we have legally up to 2 years from the purchase).
I know this may be "unethical", but, from my point of view, no more than their denial of repair a faulty phone since the first month within the warranty period due to a software-based temporary modification (which I repeat, I did in good faith to try to repair it via software -installing official CM and MIUI roms- before sending it to RMA). But, as I cannot prove that the phone was useless before unlocking the bootloader, and HTC takes refuge in the "Unlocking the bootloader COULD void the warranty" from HTCDev, this is the only thing I can do... Obviously, I am open to any suggestion in case anyone would like to use my HOX as a "guinea pig" for any experiment that could serve the community.

Then, time to throw the HOX to the bin I have made some numbers, and the mb (100-120$), plus the display (180$-200$), plus the wifi module (20$-30$?) is more than what a brand new Xiaomi Mi3 64gb would cost, free, debranded and without voiding the warranty for installing a ROM.

their are ways to return the phone to it's out of box factory state, so it looks like it was never rooted
HTCdev.com do not log your usage and deny you repair for requesting an unlock. Their is no proof you ever used it.

HTC does track that. If you unlocked the bootloader, they know about it.
All they know is you asked for a unlock code. They have no way to prove that you used it.
If you return the phone to it's original state. Theirs nothing they can do.

I don't know if it's as cut & dried as that. Like clsA said, they don't know whether or not you used the unlock token.
HTC's FAQ references the warranty implications and the warranty issue is also referenced in their explanation about unlock vs S-ON/OFF.
From my reading of their explanations, unlocking does not automatically mean warranty claims will be rejected. It simply adds an additional element to the process of determining whether or not the issue is HTC's responsibility or the user's.

True. But they told me that I would need to send it in if I had any issues, then they would determine if I caused it by unlocking the bootloader or not. (like you said).
I've never made a warranty claim with HTC before, but my guess is that while they'd need the phone to be sent in, they would be looking for physical proof that its bootloader was unlocked. I suppose they might ask you directly if they look at the HTCdev request record, but more likely they'd just check the phone itself.
I'm afraid you probably can't avoid unlocking the bootloader via HTCdev - modders aren't going to spend time on a new method when HTC is being so accommodating. On the flip side, their friendly stance towards modders indicates that they aren't necessarily looking to give them a bum rap.

So basically you trust what HTC told you instead of what you learned here on XDA ?
Maybe HTC will tell you how to S-Off and reset your phone to Stock also

**theoretically** HTCSync Manager, and the CheckinProvidor apk could in **theory** could dial home" and report it, .... still whether true or not, htcdev unlock, is not only as vague as vague can be, but it does say "it may void warranty"... it does not say it voids it defacto (especially if it's a hardware problem)
anyway, TL;DR what this was about anyway.... but if i can that many boxes at the pharmacy, it must be true

Yeah, I get both of your points. I would think the same exact thing too. Especially if I have a custom rom, there theoretically should be no way for them to prove that I USED the token, just that I got the token.
Based on my experience with HTC support (HORRIBLE), I wouldn't be surprised if they just charge you if you got the key.

I can speak from personal experience that HTC will not deny service simply because you unlocked. I s-off'd and modded my M7 to hell and back, and they still fixed the pink camera defect for free.
From what I have heard from over the years, HTC may have some undisclosed methods of knowing when the bootloader has been unlocked, even when the phone has been restored to bone stock. Whether this is true, I cannot say, but I wouldn't be the least bit surprised. HTC's historic friendliness toward modding may well be in part because they know they can tell when you've screwed things up on your own.
So if i ask the token from htcdev and i don't use, void the warranty? But i don't use.
But if i use the token and unlock my bootloader and i buy a s-off and set back the flag: Locked , void the warranty?

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

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.

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,...).

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.

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
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.

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

This. And there are people saying the EU is a bad thing in general

Yup, Motorola, help users void their warranties outside the EU by not letting them relock again. Way to go, guys and gals
Thanks for the insightful post, FeeMale, much appreciated :good:

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.

Did someone mentioned they should do this? (Re/un)locking the bootloader and warranty are two different things.

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.

As said before: a faulty screen, mic, button, speaker, mainboard,... has generally nothing to do with an unlocked bootloader.

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…

This is your advice/opinion. Everyone is free to have different ones

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.
