What is the Nexus One Warranty worth?

I am an Android Developer, but so far I've avoided rooting my phone or trying custom kernels, but lately I get the feeling I could learn so much more by really getting behind the curtain so to speak. I keep reading that if you root the phone you may void your warranty and no longer get over the air updates.
I'm on AT&T an paid full price for my Nexus One. I also got the phone engraved so I'm wondering what value if any the warranty actually has. Is it worth mucking around with custom kernels on the Nexus one, or should I get a cheaper dev phone like the G1 ?
Looking forward to hearing advice from other developers and what you've learned versus the risks involved.
Oh, Do you still get OTA updates as well?
I'm interested in hearing from people who decided the warranty was or was not work the risk. Looks pretty easy from what I can see.
Thanks all.

Just root it without unlocking the bootloader and you're good to go

root is fun and even better you can keep your warranty

Does using the technique of not unlocking the bootloader also mean you can run custom ROMs and/or recoveries? Or just gain root access to the stock ROM?

You CAN root your Nexus One without losing your warrenty.
I had my bootloader Unlocked, then i got a issue with mounting SD cards.
I sent the phone to HTC Repair center and just got it back today with the issues gone and Bootloader locked
Unlocking your Nexus One bootloader does void your warrenty with HTC, but if you experience hardware issues, they dont care if you unlocked your bootloader !!
By unlocking your Bootloader you can put whatever ROM on your phone you like, doesn't have to be stock
About the OTA's.
Yes you will get them if you run Stock ROM's.
You will not be able to install them however since you are not using a stock recovery image.

Wow, didn't know they didn't care about unlocked bootloader as long as your problem is in hardware. My GPS doesn't work at all and I'd like to send in my phone for repairs but the bootloader is unlocked.How long did it take for you to get your phone back?

I sent my phone from Denmark to UK, it took 1½ week quite fast

Can you point me to a link with instructions on how to do this?
I've found a few videos and articles that say this can be done, but reading to the end they all say seem to be closed or say not to do it.
Is it still possible to root the phone without unlocking the bootloader? I've searched google, but keep coming up with dead ends.

Bootloader relock

Is there an option to lock the bootloader again after unlock?? for warranty things

8don't know but I don't think it will work cause of custom boot image.

I don't know. I have flashed the v20a (leak version) and unlock its bootloader, then rollback to official v10e, and then flash the official v20a and the bootloader is already unlocked. I think its been unlock forever maybe????

Supposedly, you can flash a v10x firmware and it'll show as locked again, if I'm not mistaken. Although if they update your firmware back to a v20x, as they probably will, it will show as unlocked, and they might have a way to know when/how it was unlocked, and claim you had it unlocked before.
My advice (and personal intention) is, unless you're a developer, do not unlock the bootloader unless you're willing to risk voiding your warranty.
Although I'd be quite curious to know if they'd have the guts to invoke the unlocked bootloader for someone that goes in with stuff like dust between the screen and the Gorilla glass, or hardware failure of some sort.

AFAIK when you unlocking bootloader you actually write some data to a special memory called fuse. This can be done only once. Therefore it is not possible to be locked again. But it is possible to ruin the the fuse if you do something wrong and you lose forever possibility to unlock.

Well I was on leak v20a and unlock it and flashed cwm, then i flashed Official v20a .dz with lgflashtool and bootloader got locked again. I needed to unlock it again. You can try that.

I flashed between 20a leak , official 20a and 20b, and not once i had my bootloader relock by itself

With lgflashtool or kdz? Well I dont have any proof of it becouse I didnt expected it would happen. Anyway I flashed with LGflashtool without battery and sim and with 910kohm cable.

i flashed atleast once with lgflashtool (screwed something up after deleting some bloatware + installing wrong unsecure img or something, all in all i couldnt enter S/W at all), and several times with kdz (between 20a leak and other 20x's).
and all troughout this bootloader stayed unlocked (i am on eur-xxx, so i unlocked my bootloader the day the method was found, if i recall correctly)

It may be an isolated case. You never know with LG But i am sure it was locked again, even flashed cwm thinging it stayed unlocked then gave me security error when I tried to boot recovery. So i unlock it again. Mine is also eur-xxx.

Bootloader can't be relocked. When you flash kdz with all usual methods available for p880 you also flash secured bootloader and system recovery too. So you must flash these two again from adb every time you flash new kdz. Security error may appear if you don't flash unsecured BL before CWM.
Any way regarding warranty I don't think that LG service will bother to check bootloader state if device is bricked or something.

It can be relocked since mine was in fact relocked. It just that we need to find way. Unsecure boot.img has nothing to do with unlocking bootloader or properly running recovery. It just give you root access from adb. It is property in ramdisk in default.prop ro.secure=0. And they will sure check bootloader unlock status, they even developed Windows app for root checking.

I'm saying that secured bootloader won't load unsigned recovery. So maybe thats reason why you got security error. Anyway if you think unlocking is reversible maybe its best way to ask LG. Their FOSS section replied for unlocking process, maybe they answer you.

If the device is bricked, they'll need to find the problem before they solve it. They'll surely run diagnostics on it, and a phone diagnostic tool that doesn't diagnose something as basic as "has someone been messing with the bootloader?" isn't that good of a diagnostic tool at all..
So yeah, I'm pretty sure they'll check it. And even if I weren't, some LG support centers (the portuguese one being one of them) have mentioned that unlocking the bootloader will void your warranty, and the warranty itself mentions it (by saying any change to the provided hardware and software, which the bootloader is a part of, will void the warranty). So, at the very least, we should leave it as a warning to the community that their warranty might be voided when unlocking the bootloader and/or rooting their phone.

My point is that it is useless to try relock your phone.
I agree with you completely in everything you said about warranty. I think there should be warning about warranty. Also there still no need to unlock while we waiting for custom rom (CM).
Anyway I'm more than year on this forum and I never saw someone refused by LG service because their device is modded somehow.

Yes, but Asus's policy wherever that person bought the Nexus 7 might be different that the policy for LG in our respective countries...

I borrow some text from a blog :
This is a joint blog post written together with Carlo Piana with the goal to disband some popular FUD that you lose your warranty if you flash or root your device.
Does rooting your device (e.g. an Android phone) and replacing its operating system with something else void your statutory warranty, if you are a consumer?
In short:
No.Just the fact that you modified or changed the software of your device, is not a sufficient reason to void your statutory warranty. As long as you have bought the device as a consumer in the European Union.

It clearly states that not only rooting but also flashing your device with a custom rom , can't be held responsible for the defect at a device.
A friend of mine had a faulty screen on his galaxy nexus and gave his device rooted , of course the store who sold the phone refused to repair it , but after being aware of this directive and to avoid further legal actions from the buyer's side, they agreed to repair the phone at no cost.
I relate this case to the thread for the guarantee part since an unlocked bootloader is needed to flash custom stuff to it and is part of the software imho.
This is the source text.

It's nice to know that directive. People speak of them having to fulfill the warranty if the root/unlocking isn't directly linked to the problem, but this gives us something to use in case they don't do it voluntarily.
Although, keep in mind that any problem you cause due to your rooting (e.g. deleting system files, freezing the wrong apps, etc.) or bootloader-unlocking (e.g. deleting your bootloader, incorrectly installing a ROM/kernel, etc.) will probably not be covered by warranty, as it was your action that caused the error.

[Q] how can I make my warranty back ?

Using big text doesn't make it any more likely that you'll get a response - it just looks bad
Just flash the origninal KDZ for your device/region and it will be back to 'Stock'. Your warranty shouldn't be affected simply by rooting the phone (certainly in the EU and UK this is true) unless they can prove that you have over-clocked the device and damaged it that way.

and can you tell me from where can I get the origninal KDZ for my device/region ?
and thank you so much

Try to connect your phone to your PC and use the LGMobileSupport tool to force an update (It's somewhere in the upper right menu's) That should bring you back to stock and unroot your device. Please note that some repair centers will tell you that you have voided your warranty by unlocking your bootloader/altering the stock firmware, but as long as you are in the EU, like SimonTS said, software alterations don't void your warranty as long as it isn't the cause of a faulty device.
P.S.: In my opinion a bigger font doesn't make the reading any easier, so please stick to the standard size

If he flashed 442 he probably unlocked bl (unless he was going for brick)
If you unlock bl drm keys are modified and even if relocked any service center can tell it has been unlocked
Accepting warranty claims on these basis is usually entirely subjective to the service center's will

If you are in Europe you are fully covered unless they can prove that the damage is a direct result of unlocking the bootloader - e.g. blown CPU through overclocking. As he is in Egypt he is likely to be on far more dodgy ground.

Technically you are correct, but the matter of fact is that even flashing a kernel which is working for everyone without trouble can give them grounds to counter any claim.
You send the phone in most likely for hw failure, kernel and bl control all hw related activity,
hence tracing any issues back to user activity is in fact a brief step, that's why I said that
it's not impossible to get a claim warranty accepted but rather it's entirely subjective..

You can install any custom rom but for the warranty a stock rom must be on it.
It doesn't matter if you've tried custom roms before.

Hi Anmol150704,
What NOSS8 said basically.... You can do what you like with the phone once you get it, but for the warranty to be honoured.... you need to return it to stock before claiming or they will blame the custom rom for the issue. So as long as you device is functioning enough to return to stock, you should be ok.
And unlike Samsung, there is no Knox/Triggers that I am aware of that they can tell if its been flashed or not. Which is the main reason I came away from Samsung, due to the forced compliance to stick to stock if you wish things to continue working or claim a warranty.
Cheers, Lister

But don't worry if your phone is dead with a custom rom and of course you won't be able to reinstall a stock rom, there is EDL mode but using this mode the warranty is over (software problem only, not hardware).
By following the flash instructions and informing it beforehand, it is quite rare to destroy the phone.
Xiaomi is solid.

All clear , thanks a lot

Yes you can, I recently reverted back to stock miui 13 from Evolution X with the help of Mi Flash. All you have to do is to download Usb drivers, Your device TGZ Firmware and Mi Flash Tool. There before flashing you can select lock and clean/flash and the device will be sent to locked status once again.

Sellers buy from Xiaomi, the warranty conditions are set by Xiaomi, of course, the warranty period is different depending on the country.
If there is a beta version for your Xiaomi model, you can unlock the bootloader with Mu unlock which, as a reminder, is an official tool provided by Xiaomi.
If you buy a Xiaomi in one country because it is cheaper and you used and lived in another country, the warranty will be denied by Xiaomi.(common case where the seller refuses the guarantee and send it to Xiaomi.).
