Hi,
I am considering getting a Galaxy Nexus from Google. I have never had an android phone before, so I might not be familiar with some of the lingo. I would like to know a list of common possible things that would void the Warranty that comes with the Galaxy Nexus. I understand that dropping the phone into the toilet or damaging it in anyway voids the warranty. I am looking for the software things that people do to their phones that cannot be undone.
e.g. If I root a GN, can I reliably unroot it so that Samsung would not know I rooted it in the first place.
Also if I flash another custom ROM is it easy to get the factory stock ROM back inside if ever I need to send the phone to Samsung for a warranty claim.
Basically I would like to know if there is anything like flashing a custom radio or something like that which cannot be undone if I needed to send the phone in to Samsung regarding a warranty claim.
Thank you,
O. O.
P.S. Does anyone know how long the warranty period is if I buy the phone directly from the Google website? E.g. 90 days, 1 year etc.
any software modifications can be undone, the only thing that would void the warranty is if something happened to the hardware. i've bricked my S2 before and sent it to someone for getting it repaired, which they had to open the device to do so. they didn't fix it so i sent it to Samsung and they still repaired the phone for me. so things like water damage would definitely void the warranty.
Thanks

Thank you. I guess that confirmation was what I was looking for. I somehow thought that using custom ROMs or Radios could not be undone.

No matter what you do to the phone it can be undone with factory images and relocking the bootloader.
water damage. physical damage. software, and most firmwares can be undone.
you cant get water out of circuit board once it hits it.

yep take the battery out as soon as you can, or itll start burning the chips inside.
Galaxy Nexus Phone Warranty period
Hi,
I asked this as a PS in my original post, but I did not get any answers. I wanted to know how long the warranty period for the Galaxy Nexus Phone was.
It seems to me that the warranty period is 12 months, and you have 14 days (according to Samsung, but 15 days according to Google) to return it for a full refund (minus 15% restocking fee.)
The following are my references:
http://support.google.com/googleplay/bin/answer.py?hl=en&answer=2662730 -> 12 months limited warranty.
http://support.google.com/googleplay/bin/answer.py?hl=en&answer=2411741 -> 15 days return with 15% restocking fee
http://www.samsung.com/us/support/service/warranty/GT-I9250M -> 14 day return
http://www.samsung.com/us/support/owners/product/GT-I9250M -> 12 months parts and labor warranty
Thank you.
O. O.
Where exactly do you go to see the 0x0 or 0x1 flag?
Also, is warranty voiding the main concern? Is the 10.1 a 90 day or 1 year? Full of questions tonight, but thx in advance.

Reboot into download mode:
Turn on tablet holding volume down and power button until the screen turns on. Press Vol up to continue. On the next screen you will see: Warranty Bit: 0. Once you root and flash stock recovery back this will turn to a 1.
The warranty is 1 year. And yes, it technically will be void after you do this. I still maintain that that if your screen dies or hardware button comes off that they can't blame software for it. Now if you brick your tablet by farting around with stuff you don't know how to do and then try to get Samsung to fix it then that is a different story. Only time will tell before we know how Sammy will handle this issue...
I actually chatted with Samsung tech support about the Knox trigger and the warranty and they said that if their techs see that the counter has been triggered, the warranty on the Note will become immediately voided. They did say, however, that they would still fix the Note for free if they determine that a part failure was not related to Root and other software tinkering.
So Rooting and using CPU & GPU overclocking apps, for example, completely voids the warranty and they won't fix it for free. But if the screen or some buttons fail and they determine that just Rooting was not the cause or related, then Samsung will still honor the warranty and fix the defective parts.

It took about a week between sending it in and getting it back. The issue I had was that the note would not reboot if you pulled the battery and reinserted without having to connect it to the charger. Before I sent it in, i flashed back to stock using ODIN. I checked the status of the repair and it said they had replaced a component. I wasn't sure if they were going to do anything since I had tripped KNOX counter.
**The kicker**
I got it back today and immediately went into download mode and to my surprise, KNOX was reset to 0X0!! I know they said they were going to flash it back to stock when they got it, but i didn't think KNOX could be reset (even by them).

Maybe they swapped the whole board?
Mine went in tripped and came back reset also and it said they replaced a component. Mine had a non working SD card slot, i figured that replacing that part would but the phone still has the same serial number and imei number, plus I had used the region unlock and it was still in place and the software wasn't even reset.

Nice. Maybe the programmer geeks here will figure out how they did it and make everyone else one.
Not that I care about KNOX and wish it would just die already.

Same here. Used region lock away before and it sim unlocked my note. I got the unlock code from tmobile but didn't even have to use it. Unlock was still in place when I got it back

Thing is, the Knox warranty gets voided by a private key missing from the bootloader. Most likely, they are just flashing it back to stock with the signed bootloader, hence returning it back to 0x0.

Yes but this goes a long way to proving that it isn't an efuse as has been suggested in the past and has been shot around as being a fact by so many. An efuse wouldn't ever be able to be reset. Since its being reset, there is a possibility (no matter how small) of figuring out how to reset the bootloader so that it is signed when it gets sent in for warranty or traded in for JUMP.

I agree. I never thought it was an e fuse myself. But private keys are nearly impossible to crack, unless released, which I doubt Samsung is going to leak.
If they put an e fuse in the phone, they would lose money replacing parts during their manufacturer warranty.
But, here's to hoping it does get cracked one day...:beer:

Even if it is an e fuse they probably able to just solder in a new one.
If software then they simply flash the code and it resets.
We just need to talk to someone there. I know its hard to get a hold of anyone let alone get this info out of then.
But cool you guys got it back reset.
I think it is like the HTC One tampered bootloader setup.
Just give it time and we will have a way to reset it.
Yeah there is a tread in the international note 3 forum about this same thing. Couldn't find it with tapa but the topic was quite a few pages long last time I checked. Appears Samsung had the ability to rest it with their magic equipment.

There could be many possibilities here:
1. They replaced the whole device, motherboard, or CPU. The motherboard contains the CPU which supposedly contains the efuse. Replace the whole board with a fresh stock board and it will be reset. They definitely have the ability to load your old unit's serial number/IMEI/etc. onto the new board if need be.
2. The Knox flag is an efuse, but there are backup fuses. They could have set it so that a tripped fuse can be "reset" by blowing yet another fuse, which in turn would make the knox flag look at yet another fuse for the status. Since efuses are likely just one-time programmable memory there's probably millions of potential fuses in the chip. OTP memory is often available in the hundreds-of-KB to MB range on integrated CPU chips like this.
3. The Knox flag isn't an efuse, but rather a bit in EEPROM or Flash memory. If this is the case, they can reset it by just erasing the secret location that holds this status. It's possible the CPU has a small bit of EEPROM memory inside that could hide the bit from being found in the main EMMC flash. I have no idea if this is the case on this particular SoC though.
I highly doubt the efuse is a soldered on discrete component they could just replace. For one, it would have been found on the board during teardowns and two, I'm sure we'd be seeing "knox reset services" offering to replace the blown fuse for a price. Plus it would increase cost, something no high volume manufacturer want to do.
Mine bricked flashing from Wicked 4 to 5, couldn't Odin stock back and my backups wouldn't work either. T-Mo overnighted me a new one after the tech at the store tried to boot it up a few times.

No, that is not accurate - that theory was tested by re-programming the flash directly with JTAG programmer and it failed on Qualcomm-based devices where something IS stored in qfuses (but there are rumors it might work on Exynos-based devices and the latest generation of JTAG programmers that can also access the "invisible" partitions of flash.).
I agree someone on here will cracked it

While I'm all for enthusiasm, positivity and support for the community I think you should ask Verizon modders and Moto modders.
Aside from the fact that as we find exploits that only makes the next exploit increasingly more difficult to come across (as we are pointing out the weaknesses in their systems in the process, effectively helping to harden the security wielded against our own community...for good and evil), if this e-fuse thing ends up being what a lot of us suspect it is (or, worse yet, what they claim it is) then there ain't much to "crack," sadly.
Thankfully this has the potential to be an extremely elaborate system. The more elaborate it is the more vulnerabilities will exist for it. Though, again, as we exploit vulnerabilities we are only helping them to harden the system against future compromises of said security.
...There is a very high likelihood that in the not-so-distant future we'll have to just get a Nexus device to ensure custom ROMability...and that's assuming that El Goog doesn't turn to teh evilz outright.
Either way, here's hoping for the best.
Someone posted earlier about trading in a device with Knox tripped concerned about JUMP upgrade eligibility. I would say it isn't an issue, as a T-Mobile Retail Sales Rep not a damn person in store would even know what Knox was anyways, and the people who did would not care if it were tripped.

I was having issues with my Note 3. (Unit becoming unresponsive intermittently) After trying to clear cache(s) and reverting back to stock via Kies, as well as not installing any apps, AND having it freeze on me during initial setup, it became clear that the device had an issue. Sent it to Samsung (Plano,TX) and the technical assigned it a "BER" (Beyond Econimical Repair) status. They shipped it back the same day and received it via UPS exactly a week later from when I mailed it out. In detail, they didn't even touch it because Knox was voided.
Not giving up, I went to a TMobile store and told them the symptoms and replicated the issue. I also mentioned that Samsung wouldn't fix it due to Knox being tripped. The manager at the store was helpful and explained to me that TMo has a warranty exchange program separate to the manufacturers. So, he verified that it was a TMobile phone (checking IMEI) and ordered a replacement Note 3. I paid the $20 processing fee. I would then simply have to send the defective unit back. I asked about Knox begin tripped. He stated that as long as there isn't any physical damage (screen) or water damage, that I shouldn't be liable for anything else. (He inspected the unit and deemed it was free of those things)
Anyway, he did mention that the unit could be a new or refurb depending on what they had in stock. I told him that it didn't matter as long as it the replacement works. We'll see... The unit arrives in five days.
That makes me feel great incase mine ever breaks. I cannot live without root.

There's a thread on the T-Mo JUMP! here in he general section that corroborates instances of JUMP! and warranty returns not affecting warranties. In fact, I sent my knox tripped N3 back to T-Mo on JUMP! warranty replacement last month without incident.
Hi all,
I've had a bit of experience in rooting and flashing, back on my old Nexus 4. Haven't done it in awhile due to my Nexus 5 stock being bloody perfect in my opinion.
I'm going to get a Samsung Galaxy Tab S 10.5, and I've heard about all the bloatware. Obviously I would like to remove this crap if possible, but I was wondering about warranty issues. Is it now possible to restore the tablet back to a state that the warranty provider will not be able to tell it's been rooted/flashed (and voided warranty)?
Cheers.
Nope. Once knox has been tripped, you cant get back warrenty. There isnt even a root method that doesnt void knox either. What I do is wait like month or two before rooting to see if there are any faulty parts. Then i root and void warrenty.

Please read this, then close your case.
I just got my tablet back from Samsung. My screen stopped working so I went back to the store and they sent it back to Samsung.
I was a little bit freaking out, because it was rooted and then some. (had scratches on the side/cover, I've taken the cover of it once)
Now, 2 weeks later, I just retrieved it.
Tablet is fixed/replaced. Warranty was NOT voided.
And it looks like they really fixed it instead of just refurbishing/replacing. They replaced the hardware (broken mainboard, usbport, cables), de-rooted it and patched it up back to normal factory state.
I even got the stock recovery mode from Samsung on it, which they used to patch it up.
And the bootloader says KNOX WARRANTY VOID: 0.
I've looked in to this and found that Samsung is 'okay' with you rooting your device. Your warranty does NOT get voided if you root it!
If it breaks down due to software or hardware failure that is not of your own doing (i.e. not having it dropped/submerged, you get the point), Samsung will cover the first 'repair' you sent in.
Atleast here, in the Netherlands.
Just thought you guys should know this, as everybody is 'tripping their knox' and worrying about warranty.
In the EU there is a law saying that you are allowed to jailbreak electronics you own without losing warranty. So unless it is brokenot because of negligence including bricking,, they should fix it.

It has to do something with Samsung. Depends on each thing that happens to your tablet. I think they only fix it once when Knox is tripped.
Europe has stronger consumer protection laws. I would not count on it in the U.S.
Yeah as I said, in the UK/EU yes. No idea about elsewhere. It is nothing to do with one fix if tripped its to do with consumer law.
I walked in the rain very briefly and have an Otterbox on it... What is the best way to determine that it is a hardware problem and what are my options? (I have the phone for nearly a year, I doubt warranty applies).
I am get pretty tired of using software home button. Note - button doesn't work in recovery mode either.

The warranty is for a year. If the Knox bit Is tripped it's said warranty is voided. I've seen many members who have had Hardware issues repaired even with it tripped after flashing back to unrooted stock. Call samsung support... Don't mention you are rooted if that's the case.
