Does unlocking bootloader/rooting N9 void warranty? - Nexus 9 Q&A, Help & Troubleshooting

I was told Nexus devices warranties aren't voided, is this true? Just not 100% if I want to keep my N9 but I wanna root it to see if it can satisfy what I need it for
"But if you restore the factory Image and relock the bootloader they will never know... effectively restoring your warranty." - Is this true? From a Nexus 7 thread
Thanks!

When u unlock your bootloader .. its says it "may" void warranty. Undortuantley i am unsure of what that "may" means. But as far as i know unlocking bootloader wont void your warranty. But correct me if im wrong.

It's a nexus, no warranty void when unlocking/locking rooting/unrooting.
This is how nexus worked since the beginning.
If they change this, nexus would sell probably not at all anymore because it would be like every other tablet/phone beside the stock android.
So no, no warranty void. Period

HTC's documentation in the box makes it clear that unlocking voids the warranty. It looks like a blanket policy, but there's no other info to the contrary.

Yeah, so that's why it says "May".
Buy from HTC, lose warranty with unlock.
Buy from Play, no such problem.
I just unlocked and rooted mine. I'm feeling underwhelmed for $400 though, and I'm considering a return under Googles:
If you aren’t happy with something you bought, you can return an item within 15 calendar days after the day you received it

It doesn't say anything about being unable to return after unlocking. I'd just relock and put it back to stock, though Google or their service company (?) would likely do the same anyway.

I doubt there's different warranty information in a mass produced box, regardless of where you ordered. But if you have it in writing, you're safe. I expect most people here aren't too worried about their warranty, but I prefer to know the actual policy rather than hope for the best.

You can always relock the BL with fastboot OEM lock and like magic it's locked again

After locking mine again (for warranty return), it flashes "This is a development device not intended for production use" in red letters at the top of the screen during boot... I guess I'm about to find out if it voids the warranty.

Yep, that's exactly what I just did. Thanks! I did a little more searching and found a few others making that suggestion. I followed this process for a manual flash (after the flash-all script failed), then `fastboot oem lock` before rebooting. I no longer see the "development device" message!

Has anyone claimed warranty after unlocking bootloader using the official method?

Has anyone managed to get theirs phone repaired after unlocking the bootloader through sony website?
Also everyone says that you lose warranty when you unlock the bootloader via sony website. On ythe website http://unlockbootloader.sonymobile.com/
I found this text:
Please note that you MAY void the warranty of your phone and/or any warranty from your operator if you unlock the boot loader. Sony Ericsson can then no longer guarantee the full functionality of your phone, and will not be responsible for any unsigned custom software being flashed to the phone after the boot loader is unlocked. Certain functions in your phone might cease to work, and performance might not be ideal.
Well it says that it may void the warranty.......so there is a possibility that they would repair the phone even if it's unlocked - I'm talking about hardware repairs.
I did. Well, it wasn't repaired, but that was probably because they didn't recognize the problem (burned in screen).
On the repair ticket they said 'Modified software' but they didn't charge me anything.

Thanks a lot. Looks like I'll be unlocking my phone today
its better when you re-lock bootloader back then they will repair phone without problems
Technically they can see missing DRM certificate, if you unlock using official way. Not that they will specifically look for it but it does show when they connect it to program they use in service.
Just a note

I'm in Poland - they seem to have a deal with a a company called Regenersis.
http://translate.google.com/transla...f=1&u=http://www.regenersis.pl/CustsS_17.aspx
It is a "phone repairing" company.
So Regenersis is an official service center for many mobile companies in Poland including Sony. The closest office would be in Warsaw.
I used to have a wildfire S before and this question came up in that form too, so I'll give the same response here.
Unlocking your bootloader DOES NOT void your warranty.
' Sony Ericsson can then no longer guarantee the full functionality of your phone, and will not be responsible for any unsigned custom software being flashed to the phone after the boot loader is unlocked. Certain functions in your phone might cease to work, and performance might not be ideal. You might also damage your phone permanently. In the worst case, unlocking the boot loader will cause physical injuries or material damage, for example, due to the phone overheating.'
I.e. -- If you OC your phone or install a modded kernel which screws with the hardware and breaks it it isn't their responsibility
The warranty remains though, obviously the proviso is that you don't flash a custom ROM or anything, but even then the main thing is that if you break something and re-flash stock they probably wont know tbh.
So (broken record style) No, unlocking your bootloader DOESNT void your warranty, breaking your phone by OCing it too much or screwing with it in that matter does render them non-liable for it, if your phone had a fault which was not due to custom ROMs or anything though and was in fact a sony issue warranty is maintained.
Edit: Matter of fact, within the EU they CAN'T void your warranty for pre-existing faults.
I wish people wouldn't make assertions as to the law without properly reading T&C first & some basic knowledge on EU warranty regulations.

Help please! HTC amaze sending back to for repair.

Please help read!!
So my HTC amaze died on me about 2 days ago I was listening to my music in my car connected through Bluetooth then a cop passed by and everything shut off haha coincidence haha anyway went home had no service like absolutely nothing thought nothing of it and went to sleep, next morning still nothing and ever since now its dead. Called HTC they said most likely its T-Mobile not the phone but they sent me a replacement back cover (which is cool) because the antennas are on the back anyway I know this isn't the problem because even without the back cover you can still get signal. So I took phone to T-Mobile put new sim tested and nothing so now I know its the phone not T-Mobile. Anyway my question is how can I prepare to send back to T-Mobile I have relocked phone put stock recovery and put leaked ics Rom. So is that bad that it sais relocked and bad if I'm using leaked ics rom I know its voids warrenty when it sais relocked but my software and phone everything works perfect its just the signal so will they fix it? And when I send in could I send phone with a eBay bought battery not HTC one so they could send me a new battery or should I send only HTC battery, phone, and back cover. And also is there any fix for this so I don't have to send in? Please help thanks
You can install official ruu and that will update and install your hboot to locked, which is what tells them if it's locked or relocked. If you don't know how to do this you need to read. Also I've been hearing that ever since s off became available they are considering as voiding warranty not sure if this has taken effect yet or if it matters but just to be sure if your s off read the section that tells you how to s on.
Now before you send have you tried toggling airplane mode on and off ? Still no signal? Flash the official ruu usually fixes these issues. If still no signal then I suggest you send it in.

It's still gonna say relocked, the only way he can get it back to "locked", is if he s-off's the device, once s-off is successful, it automatically puts it as locked all over again, he can leave it as lock, restore a stock ruu, then using, use the command: fastboot writesecureflag 3, that will s-on the device along with everything else being complete stock.
Hmm ya I know how to ruu wich I did but I ruu the ics leak and now everything's stock accept that it sais relocked and want to know if that's gonna be a problem for warrenty when I send it in? It shouldnt since its not software problem? And ya hear how to s off just don't want to try wire trick and all that. And yep tryed turning off and on airplane mode turning off radio taking T-Mobile to change sim cards have original stock Rom tryed *#*#4636#*#* all those tricks but nothing.

When you chose to unlock boatloader you voided your warranty. So by saying relocked it tells them you unlocked it. You need to do what dark nightmare says or you run the risk of not warranting your phone. Luckily for me I "lost" my phone so I couldn't send it in.

aw glacierguy thanks for the positive attitude! hope everything goes good for my phone!
So update for everyone i called HTC back and told them to cancel my back cover replacement for the Amaze because i know this is not the reason why i have no bars! because without that cover i still had bars and i know the amaze has some more antennas inside the device. Anyway i told them that i want to send the phone in for repairs so now everything set up and just have to send the phone on its way :crying: hope its a hardware issue and they can fix it. In the mean time got kinda intresting email from HTC saying
"After we receive the device, we will diagnose it and if there are any damages that fall outside of the limited warranty, we will contact you with a quotation to repair. If you choose not to repair, a service fee of up to $35 dollars will be charged and the device will be returned unrepaired."
Yes kinda scared me but hope i don't have to pay anything for this repair so everyone wish me luck and ill let you guys know how everything goes.
Sucks im probably not gonna have my phone for about a month
Just asking, but even if you managed to get the phone completely back to stock and say "Locked" isn't HTC able to tell if you've unlocked the bootloader via their unlock process on the website?
I was under the impression that the entire reason for the HTC unlock process (getting the key from the phone, etc) was so that they would have a database of phones that have had their bootloader unlocked? I'm kind of new to this but that was my impression.

I think they do have a database, yes, but that only tells them that you requested the file, they can't know you YOU used the file, can they? Huh? Nope, if they knew you used the file, that sir would be invasion of privacy, then they'd be paying for more than just a simple device replacement with the lawsuits that would be hitting them from every mobile device owner using their product.
So once it says "Locked", they can't say you voided your warranty, then they'd have to prove it.
Yes what darknightmare said you could get token but maybe last second decided not to do it haha anywho sending it saying relocked hope they fix hardware issue if not maybe gotta spend money?

They don't need a database. There is no way I know of to get a "locked" phone once it has been unlocked. It will say "relocked". So HTC knows it has had an unlocked bootloader. That doesn't necessarily negate the warranty so far as HTC is concerned. I've read that they have fixed what are obviously hardware problems. But they won't fix anything that a ROM screwed up unless you pay.
The wildcard is T-Mobile. They may or may not be picky about these sort of things.
Ya for sure lets see what htc sais shipped out today through ups htc should get it thursday hope ups loses or breaks my packagae have 300 dollar insurance ha but yep anyone know of any prices for this fix?

Sir, when I say there is a way to get a "locked" bootloader, please don't argue with me unless you can prove my theories wrong, , I have tested and proven everything I speak of, I don't just say something because I want to.
Edit: For the record, once it says "relocked" you have voided your warranty, if you read the agreement on HTC website when unlocking your bootloader and the message on the device when unlocking, it clearly states by unlocking your bootloader you are voiding your warranty.

100% on what Dark Nightmare said, i followed the procedure on the forums on how to completely restore to stock. i was s-off etc.. after it was all said and done, my phone was locked and ready to rock. I sent it back after my replacement arrived and all was good.
Just read through General, Q&A and Dev section, Trust me the answer is there. It's ALWAYS there. I used the GB juopunutbear S-off tool instead of the ICS tool cause i am retarded and didn't take my time and got stuck because of it. I did 2-3 minutes of using the search button and i was fixed in a second!
First of all! Yes Dark Nightmare is correct he knows his stuff you can put it back to locked anywho i would first like to say thank you for all the replys to this post. First post and didnt think my question would be answered but it was and its a great community we got here, i may be new member, but ive always been on xda reading up and hacking all my phones i have went from metro pcs huawei ascend, tmobile my touch 4g and now htc amaze all rooted and custom roms also have done droid and sidekick 4g. The thing is i do have experience and learned alot.

I think my post may not have been clear. Of course you can lock the bootloader; that is how one installs the original ROM. But I was under the impression that it then says ”relocked” if you have previously unlocked the device. That warning from HTC have me a lot of pause when I read it! But I think what I read said ”may” void your warranty. But I was reading fast...

Sony wouldn't repair their yellow tints, even this is FACTORY DEFECT

Send my Xperia S in at the end of June for the yellow tints problem. Waited two weeks and Sony replied that they wouldn't repair the phone because of "illegal unlock"?? The phone is factory unlocked. Tried to discuss this issue on http://talk.sonymobile.com/thread/34135, and 1 day later my account with sonymobile was suspended. Just feel so disappointed with Sony's customer service.
Wow.
What was your user name over there?
Have you unlocked your bootloader or sent it in rooted or something like that?
If that's the case, it's normal that they didn't touch it as you lost your warranty if you unlocked your bootloader. If you rooted it, you should have restored it before sending, because technically, rooting voids your warrantytoo.
Maybe you bought it used and the previous owner unlocked the bootloader and didn't tell you?
ditto (well i unlocked the bootloader, with a code provided by SONY, which is hardly illegal, but I guess they're really playing the voided warranty issue on this)

Had got the same problem with yellow tints, but my phone wasn't unlocked and has been repaired by Sony in two weeks.
If you had unlocked your phone even with the Sony method it's indicate that warranty is avoid in this case.
Interesting...with an unlocked bootloader it still shouldn't have been an issue. Your warranty is in theory still intact, just with CPU modifications and such afterwords that can void it (overclocking and such with custom kernels). In the terms it just says "may" so they avoid liability if you break it yourself. It appears in this case (and the other one posted above) they decided to throw that out the window and just say "meh, sorry, today, because it's cold and didn't sleep well, its your fault."
You didn't by any chance have Doom's kernel on when you sent it in?
It's almost like every center changes their interpretation of a voided warranty depending on the weather or if they just feel like it .
I wouldn't associate your account being blocked as Sony's fault though, as you picked a username that appears to be picked by bashing your head on the keyboard . It was probably what they thought was a spam account?
If you formatted the device then reflashed it with a stock GB firmware would anyone be able to tell that it had been unlocked ever?

Sony really need to sort themselves out, been going backwards and forwards for weeks. Latest issue is they are now claiming I purchased my phone in another country, it was supplied by my carrier.
Been a Sony fan since x10, but they are getting worse with cs. The phones are better, but they really need to train their staff.
My phone is not foreign, how the hell would they know in the first place? They've never seen the phone and I have never been asked for an imei number.
This is a joke now.

"nolramlb" hasn't been banned, his name is terrible, and he's made over 1200 posts in ONE MONTH, now that's some spam!
We over in the HTC forums have the same prob, unlock the bootloader then you lose all warranty on your phone. We have faulty WiFi antenna on the One X, the contacts don't connect the antenna correctly, HTC say that if you unlocked your bootloader you can't get the antenna fixed, no one can say how unlocking a bootloader and WiFi antenna can be connected in any way, but HTC are being dogs about it. As for the yellow tints, they are a common problem across the bord, it's only the glue sticking the screen and the glass, play some games, give your phone a good use to heat it up and you will find that,the yellow tints go after a week or so
It's odd to see that it seems all/most mobile manufactures some what lack customer service.

haha, that's interesting. I got that username because they said my normally used one has been taken. I've never done any CPU overclocking/mod, or never had any customer kernel installed. I don't know their "illegal unlock" means network unlock or software unlock. The phone was sent back to the repair centre with original GB software.
Here is the feedback from Sony UK's repair center, if this can help. I can guarantee the phone is working properly with photo evidence. I don't know why see put Display broken rather than "yellow tints".etc. Now the phone sounds totally dead at the Sony repair center.
Perhaps they tested it for so long it's run out of battery!
I'd be complaining like hell right now to Sony Customer Services!!

QFuse on N6P

Hmmm the Nexus 6P comes with a qfuse. It will be activated if you unlock bootloader. You can lock your bootloader back, but you cannot restore the qfuse. Qfuse is a hardware, once trip cannot revert back. Once QFuse is tripped, no more warranty.
Check the attached pic which shows qfuse in the bootloader.
read below forum for more discussion on this:
http://forums.hardwarezone.com.sg/97415852-post1515.html
What is qfuse:
Qfuses are one-time-programmable (OTP) elements that are used to enable and disable security and debug features of the MSM7xxx device. The Qfuses are implemented as anarray of one-bit fuse blocks. The Qfuse banks are used for two purposes — providing non-volatile, immutable storage of data, and configuration of hardware features. For immutabledata storage, the Qfuses are read via a shadow register which contains the actual valuestored and includes error correction.For configuration, each Qfuse is associated with a one-time write register. The value of each Qfuse is sensed at powerup and stored in a register. Blowing Qfuses is done byplacing a value to a register and applying current to the fuse. The fuse registers areaccessible through JTAG and software readable address locations.

That's not cool
Maybe the qfuse is part of the "save fingerprint partition".
Wow, on a Nexus that's a disgrace.
Oh well, I'm not really sure why we still need a lot of that.
The only reason I really needed root anymore was for bypassing tethering, but most don't worry about that with shared data.

Hmmm the Nexus 6P comes with a qfuse. It will be activated if you unlock bootloader. You can lock your bootloader back, but you cannot restore the qfuse. Qfuse is a hardware, once trip cannot revert back. Once QFuse is tripped, no more warranty.

PLEASE STOP WITH THE FUD!!!!!!
You will still have warranty. If the button falls off they will fix it. If the screen dies, they will fix it.
Software related issues would not be covered.
The Magnussen-Moss Warranty Act covers this.

Yea, but short of physical malfunctions like you mentioned they could potentially argue that the software change impacted your device via indirect methods.

If you had an internal hardware issue like a processor overheat or ram issue, they could blame it on the software

good luck in explaining that act to an offshore customer service rep who barely speaks/understands english. Also besides USA there are other countries and people live there and use android/Nexus phones.
Who cares, I have never returned a nexus device because it got broked coz I is dumb can't use ADB durrrr hurrr durrr.
Honestly 99% of use won't give two ****s, preparing a nexus your self is easy enough once parts are available, most users just want root and are aware this process could cause damage regardless.
Who's scared of a Qfuse really ? I bet someone figures how to write back to it just for fun anyway.
Remember Samsung's KNOX . . . fat lot of good that was can't bypass that they said . . .
Just had an online chat with Google regarding warranty status. Yes it is void while boot loader is unlocked, but if re-locked it is back in warranty again.

so google doesn't check the status of the qfuse?
Doesnt seem to no. Just that the boot loader is locked!
I also asked about the fingerprint scanner and rooted devices. Wernt a able to give me any info, but at least they were honest about it.
I also have never had to return a nexus. Nexus 4 5 6. And 7(2013) models. If I did. I would play stupid. It's worked on my other phones I have had to return.

			
				
That's amazing! Contact google and you get two different answers!

My N6 with a bad battery disagrees with you, if N6 has efuse I would have been out of luck with Moto in replacing it under warranty, you can't replace a sealed bad battery with ADB.
Definitely want to get a concrete answer on this. I was planning on unlocking the bootloader right when I got the phone but now I'm skeptical. If this really will void the warranty, **** Google. It's a nexus. We should be able to do whatever we want to.

I'm assuming the "re-lock" guy didn't know that the fuse value was different.

Relock bootloader

I recently purchased a T-Mobile LG G5. I am not too tech savvy, and since I'm a novice when it comes to rooting, I have a question I need help with.
I unlocked the bootloader and rooted my phone. Shortly after doing so, I noticed a blister in the paint of the phone's battery/charging port tray. This is the part I'm referring to. http://www.globaldirectparts.com/OEM-LG-G5-Accessory-Module-Loud-Speaker-Gold-p/lgg5hsg4gld.htm
I contacted T-Mobile, and they offered me a warranty replacement. That sounds great, but I'm bummed out. I have my phone customized exactly how I want it, screen protector and all. I can't figure out if I want to go through the hassle of unrooting my phone, relocking the bootloader, then doing the reverse to the new phone.
Anyhow, the answer to this one question will help me decide. There's always the possibility that the T-Mobile store rep will be unconvinced the blister, which has since then burst, was a manufacturer defect. It actually now looks more like a scratch. If I go ahead and relock the bootloader, but am denied the warranty replacement and have to keep my current phone, will I be able to unlock it again? Or should I save myself the hassle and shell out $70 to buy a new battery/charging port tray?
The common sense answer is to ignore the blemish and keep using my current phone. But I'm a perfectionist when it comes to these things and can't bring myself to do it.
EDIT: I'm going to leave this up rather then delete because the answer below may have valuable information for somebody else. But there was never a blister in the paint. I feel like such an idiot. The phone came with a plastic protective adhesive that was applied so well, I never realized it was on. That's what blistered.
You could relock the bootloader, and send it back. The question is rather whether they would find out, since i am not quite sure if they can see that the phone was ever rooted. If you decide to lock the bootloader again though, you can unlock it later on again, that is no problem. I would suggest unrooting it, and relocking the bootloade, if you can not ignore that blemish. I just got mine yesterday, and im debating whether i should root it again, because i am not certain that i could re lock it and recover the warranty. I only need to root it because of adaway, since there is no custom rom support yet.

Thanks for the reply. Read my edit to the original post. You're gonna laugh.

Is there a way to unlock a relocked BL?
I bought a used G5 H850. When I try to unlock BL on LG site, I get the following message "Device ID is unmatched. Please check your Device ID. Your account will be locked if you enter the wrong Device ID more than 4 times.".
Searching in the internet, it seems that I get this message because my phone had been unlocked once.

1.) the phone id was entered to get the unlock code
2.) you can find a unlock detector in a hidden service menu
:crying: if they want to see, they will be able to see!

as I know:
that’s right! At the first time the phone was unlocked; the id was registered as "unlocked" in the LG data pool! AND unfortunately the ID was related to the user account of first registration.
Best way will be to contact the first owner if you can.

How to relock the bootloader pal?
Im curius because, even if the bootloader is locked again, cant LG search among the IMEI's and find out that previously the device was tweaked?
Thanks!

While LG will know that the Unlock.img file was requested they wont know if you have used it or not. So they will need evidence that you used the file in order to warrenty void.
