I understand that rooting does void the manufacturer warranty. However, I would like to know if they will blacklist my phone for future warranty repair attempts if I do send it in without flashing back to stock (my phone can't turn on to flash back). My phone that has been rooted for months, but now it has an issue with the battery and will not turn on. I assume they will have to fix it in order to see whether its rooted or not.

I wouldn't even worry. They go to refurb when they are returned .. I've never had any problems, anyone else?... This has also been covered a ton of times, search it... Gl

might be bad battery or no charge on it. Can't you find another battery and test it out?
to answer your question, it's the risk that you talking. Sometimes they don't care sometimes they do.
It's always safe to send it as factory condition to avoid any problems in the future.
So recently my battery drained completely (did not do this on purpose). After charging my phone back, I realized that auto-brightness was not working. Also, I realized that the proximity sensor wasn't working either because whenever I was on a call, the screen would not turn off. I was running AOKP 4.1 (Task's ROM 12.2.12 release). I was running it before with no problems. Anyways, I updated the ROM to them most recent version (AOKP 4.2.2 3.4.13 release). I did a full wipe thinking this would fix the problem, but it didn't. I downloaded Android Sensor Box to test the sensors. The Accelerometer Sensor, Light Sensor, Orientation Sensor (Screen rotation does not work as well), Proximity Sensor, and Gyroscope Sensor are not working. The sound sensor works. I didn't know how to test the magnetic sensor and the pressure sensor. How should I fix this. I have not flashed any kernels and I have not changed the performance setting of the AOKP ROM. This happened after my phone battery drained completely. This is not the first time this is happening, but previously, restarting the phone would fix it. I did some searching and in a nexus 4 thread, somebody flashed this http://www.mediafire.com/?079z7ky9nomb9i8 and it fixed it for them. I'm not sure if this is for the Galaxy S3 though.
don't flash that file. it's for another device and rule of thumb: don't flash files that are for another device.
you say this has happened before, it sounds like a hardware issue? Odin back to stock and see if the problem persists. if it does, you can probably return it under warranty.
you flash a kernel when you flash a rom, for future reference.

Yeah this has happened, but it happened out of nowhere. I bought the device sometime in the summer (June or July), probably happened in December. Also, is this what you mean by going back to stock: http://forum.xda-developers.com/showthread.php?t=1968625?
Also, I have a mac, so ODIN would not work on that. I checked out Heimdall, but I can't find out if it works with the S3? Is there any other way of going back to stock?

Heimdall works with s3. You could download a cwm flashable stock firmware zip and use recovery.
Right now I don't have time to do a full wipe cause I am going to need my phone for the next few days and can't risk losing data on it. Are there any other solutions that don't involve a full wipe?

They only way you can tell if the phone's hardware is ok if you do a factory reset.
You can use mobile Odin through google play but it didnt work well for me. Its an option but you will have really read before doing it.

So I installed the stock ROM and the sensors were still broken. What should I do now? I tripped the counter, so I would have to buy that app to reset it if I were to do a warranty replacement.

If a stock flash didn't cure the problem, it seems like it is a hardware issue. You'll need to reroot the phone and run Triangle Away to reset your flash counter. Once done you'll need to reflash stock to get rid of root.
If you are not able to pay for Triangle Away, the dev provides the apk free of charge here on XDA. You just need to search for it.
Once your set, contact either Samsung or your carrier for a replacement/repair.

ATT is the route I woulg go, but it will be a refurb. I'm not sure how Samsung would handle it, might be a refurb from them as well or a part replacement.
As far as what could have caused it... Phone being dropped, water damage or if not those, could simply be defective hardware.

I checked AT&T's website for the warranty center locations, and they are too far from where I live, and I don't have a car either. I guess I am going to call them and request and exchange. Thanks for helping me out.
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.

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:
Sent from my SM-N900T using Tapatalk
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.
Sent from my SM-N900T using Tapatalk
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.).

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.
Has anyone unrooted by flashing stock rom using Odin even though Knox remains tripped and sent in phone to Samsung for repair without issue. I am having back button issues lately but I rooted my phone. Thanks.
Samsung is pretty good about honoring warranties but I highly doubt they will honor your warranty if they see that your phone has been rooted. You should probably call Samsung and talk to them and see if they will still look at your phone and possibly fix it with it being previously rooted. There's still a good chance they will as long as your phone is put back to factory software. You just need to call Samsung first so you don't waste time. If Samsung tells you no then you're only left with replacing the digitizer yourself or at a third party repair center or getting an insurance replacement. Sorry for your bad luck.
What exactly is going on with your capacitive back button? It's possible that Samsung will go ahead and fix it because it is a hardware failure that has nothing to do with rooting your phone. Call Samsung.

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.
