Hello everyone,
We all know rooting your device voids your warranty.
But if you unroot your device will the ol' techs at Samsung be aware of it?
You see I've run into this problem: I took some pictures, didn't upload them to my laptop or a cloud service and my phone RANDOMLY did a factory reset. (More like it powered off by itself and then when I turned it on everything was gone) Now in order to run decent recovery software for the pictures, I need root. But I also want to have my phone checked out for hardware faults.
I'd like to root, recover photos (or attempt to), unroot and give it to Sammy.
For the S5 is there anything I should be aware of while unrooting?
Thanks in advance!
For now unroot dont give back warrant

It means that Samsung started using a protection method referred to as Knox. Rooting, installing custom ROMs or bricking your phone will usually trip the Knox counter which then burns a permanent qfuse. Trying to revert to stock after a qfuse is blown will still leave evidence that your phone was previously rooted.
If you root with Chainfire's mobile odin app, you may be able to avoid tripping the Knox counter. But it's not guaranteed. It's a cat and mouse game back and forth and whether your root is 100% revertible changes from time to time. Eventually someone will also mount a legal challenge to settle whether Samsung can void your warranty just because you rooted your phone. But in practical terms.. consider yourself warranty less if you trip the Knox counter on your phone.

Where do you live? If you live in the Netherlands they will not void your warranty because of KNOX, this is proven in real cases now. If you live in another country, I do not know if the law is the same as here, but you should find that out before rooting of course
Well, as suggested above.. if you happen to live in an European countries that has unusually strong consumer protections then it's moot. Otherwise do a search and find out whether other members with your exact firmware version are seeing their Knox counters tripped or not.
Breaking a hard drive seal would normally void a warranty. But Samsung will let authorized vendors break the seal for data recovery purposes. I'd imagine that they'd do the same for photos on a phone but only if you use an expensive third party vendor. If you're not in a Scandinavian country, not rich and have a very recent firmware.. you may have to choose between voiding your warranty and decent prospects of recovering your photos.
If you don't see any better prospects you may be able to run an ADB shell without root and possibly do a dd image of your deleted photos. It's key that it would be a raw sector by sector image, rather than a file by file process in the context of data recovery. And as an aside your phone should be turned off and collecting dust for the moment. Continuing to use your phone may dash any real recovery prospects.

Sounds good will look into all that. I live in Malaysia at the moment so I guess I'll have to see what Samsung says about it. I suppose if I explain it to them they might understand.
Thanks man

So, I've noticed quite a few restrictions when using apps and it's getting on my nerves.
I've been thinking about rooting my i9505 but I'm a little concerned.
I would not like to void my warranty, as far as I know there's a way to root your device without altering the binary counter (whatever that is, not that much clarification about it), but I'd like to make a full backup of the out of the box state of the phone.
So that in case anything goes wrong or I have to send it to samsung for warranty concerns or if I simply want to, I can restore the device to 100% as it was before.
Haven't really been able to find complete guides or necessary info on this matter, any advice?

Hi,
Look HERE
This is probably a really stupid question and many will get angry and call me a noob. However the question is this:
I rooted my phone quite soon after I got it, and now I read there is a way to do it which means I wouldn't lose the warranty. Is there a way, possibly restore and root again, that will mean I get my warranty back?
Of course you are free to answer how you like, but a simple yes or no, or with the addition of constructive advice is all I really need.
no you are f..ed
Teleported from my SM-N9005 from The Enterprise
I did the same thing, bought the phone then rooted within the hour. I should of read all the 'efuse' and knox warranty stuff before... but oh well.
Worst part is, i had installed knox and played around with it, rooted the phone, and when it rebooted i had knox in the pull down menu and couldn't get rid of it as it stopped working. I have now gone back to stock via kies and patiently awaiting for a knox 0x0 reset. Who knows..

There is no way to restore a rooted device to factory settings whereby restoring the knox counter and enabling your warranty. Once rooted, the device warranty becomes void. You can root and install the original ROM but the problem is the device status will show "Custom". This can be reset so things look factory to the average joe (say a store employee for a return) but the problem you have is if sent for warranty, once a technician looks at the device and runs their troubleshooting techniques on the device, they'll be able to tell it has been rooted.
Hope this helps!
I have a Canadian Telus GS4 running SlimKat, and would like to return it to stock for a warranty replacement on the "SIM card not detected" issue that I'm having.
I would like to confirm that the steps I am taking to do so are correct and possibly get some help troubleshooting some issues I am having along the way.
Step 1:
Download stock firmware from this thread http://forum.xda-developers.com/showthread.php?t=2269304
Step 2:
Download Odin 3.07 from this thread http://forum.xda-developers.com/showthread.php?t=2258628
Step 3:
Flash stock firmware via Odin.
Now on to the Questions and issues I am having.
Question 1: Is it necessary to reset the binary counter to 0? If so, then what are my options?
I understand that Triangle Away will do the trick, but it warns that I must be using a stock kernel to be safe. I am currently running SlimKat. Do I need to return to stock using the above method, then re-root, then use Triangle away...THEN return to stock again? This feels like the long way around, are there other options?
Question 2: Does it matter which stock firmware I flash via Odin?
According to http://www.sammobile.com/firmwares/1/?model=SGH-I337M&pcode=TLS#firmware there are 3 options of stock firmwares. Is the latest (from the link I pasted above in my "Step 1") alright, or should I go back to 4.2?
Thanks for checking this out! Hopefully this can help others with the same problem.

I had the exact same issue with the sim slot. But having the AT&T variant and MDL firmware is a rarity. If I sent mine into Samsung they would upgrade my bootloader to the more secure on and give me the official 4.3 update. I didn't want to loose my custom recovery, so I took it to a local iFixit workshop. Know the guy there and he fixed my iPhone 4S a few years back. Said it would be no problem for him to replace my entire sim slot for $10.
Hopefully you can find someone locally to do this for you. If you send your phone in, count on it coming back with a more secure bootloader (knox).

I am quite uneducated on the knox bootloader. I understand what it is but I didn't know it would be on the Telus firmware. A quick google search shows that it would be around 15 bucks for me to get the SIM slot fixed up. Not a huge deal...but my phone is still under warranty.
EDIT: Update - I replaced the SIM card reader in the phone and am still having the SIM card undetected issue. Either I received a faulty SIM card reader, or there are other issues with the phone.

Then you might want to send it in to Samsung. I'd rather you have a phone lol. I believe the 4.3 update will only give you knox, which keeps track of custom firmware. Your bootloader will not be locked. Sorry for the confusion.

I do plan on sending it in but am having trouble returning it to stock... :S never had to do it before and Odin is giving me trouble
EDIT: Update - my Odin was freezing at "SetupConnection" for the longest time. Went to a different computer and it worked... flashed MK6 firmware (might have been a mistake to pick mk6?) but not the phone is back to stock and knox counter is at 0x0.

Well my point was that once you get the phone back from Samsung, they will always know if you flash a custom recovery by the knox. Unless your phone had knox before? But if its at 0x0 you have nothing to worry about.

I need to do more reading on knox, but I didnt see anything about the knox flag in download mode when I was on the custom firmware and recovery, I think going from custom to the most recent MK6 firmware for the I337M put the indiciation there.
Thanks for your help.
It's also interesting to point out that since I flashed back to stock with odin, my SIM card issue has gone away for the time being. I'll update if it comes back haha.
I dont understand way they would deny a warranty on a phone that has a non-standard rom on it.
I mean if the sim slot is bad, its bad - not that some app made it bad, or the removal of ATT Navigation software caused it to break.
*yeah yeah I know, in the EULA it states stuff about circumventing the OS voids warranty
It just seems anal to spend a lot of time examining the entire OS and partitions when they can just toss in a sim card and recreate issue and just fix it.
...then again, I am not Samsung

I was under the impression that if the knox counter read 0x1 than they would not touch the phone, regardless if you touched it or not.
I have not seen a post that someone's phone was returned not fixed with a note/reason that the phone was modified outside of specification. Also imagine a dumpster of fixable phones that are untouched due to knox flag was triggered?

Wasn't that the whole point of knox? If it reads 0x1 then the warranty is void?

Well the knox flag in download mode is... "knox warranty void"
That's how it reads, or something like that.
True it can show that, but outside of chainfires explaination of how it is blown and "what has been hearing about Samsung service centers". If you read his article, there is a lot of maybes, mights, and even ends his article with "take it with a grain of salt".
Their are a lot of mad people in his chat, but I didn't find anyone saying they got denied. Samsung can do what they want, but they know word of mouth is as big as advertising is. One person saying "I installed a program, it broke is my phone and Samsung is not honoring the warranty" has a huge impact on people regardless if they know and/or understand rooting.
Knox security void can mean the phone can no longer be certified for enterprise grade applications or environments. That the security mechanism is tainted thus considered broke and not repairable.
Just my point of view - I have total respect for chain fire
Edit: Additional info
The Magnuson-Moss Warranty Act (1975) says that to refuse warranty, the company must prove that the problem with phone (or any other device that fails) was the caused by the customer.
So a defective sim card reader (unless obviously damaged by a consumer) should be covered where a modified corrupted partition table causing a boot failure (and also not a wide spread incident) may not be covered as this is more of a damage from a "non-friendly" application caused by the consumer.
Hey folks,
One of the forum moderators pointed me at this thread ( http://forum.xda-developers.com/showthread.php?t=2586586 ) as a suggestion to getting a ROM for my S4 that would alleviate the com.android.phone process crashes I had with other ROMS.
After flashing jfltespr_mk2_deodexed from micro-sd card through the Team Win recovery, my phone is now stuck at the Samsung Galaxy S4 logo screen with (Set Warranty Bit: Kernel) in the upper left.
Having looked through numerous threads on this issue, it seems there's a number of different remedies, from reflashing to simply powercycling.
There wasn't anything that was of much use in http://forum.xda-developers.com/showthread.php?t=2527706 either.
I have odin, and can boot into Team Win Recovery, or download mode. Suggestions/tips/ideas would be appreciated. Thanks.
Seems like you already have Knox tripped. And those warnings are because Knox detected modified files on your phone at boot up. I would suggest to odinto stock MK2

Go to this post and download the full stock mk2 tar file. Once downloaded extract the tar file from the zip file and install it using Odin 3.09 for best results. This will bring your phone to full stock unrooted. This should fix your phone problems. It is best to start with a clean slate. If you are still getting the force closes, then something on your data partition is causing your problem and you will need to do a factory reset after installing the tar file.
After you are up and running with no errors then you can re root your phone. I like safe root. It is quick and easy. Just Google Safe Root for Sprint Galaxy S4 and you will find it.
If this doesn't fix your phone than it might be hardware related. Also, just to be sure, make sure you don't have the L720T version of our phone. Because if you do, that is your problem.

That thread has a huge KNOX warning. I was hoping to ditch the Sprint bloatware.
Am I interpreting things right that I'm basically screwed for non-stock ROM's now?
Also, I have an SPH-L720
On the download rom screen, it reports KNOX KERNEL LOCK as 0x0, KNOX WARRANTY VOID as 0d?

You're not screwed for non stock ROMs, IF you don't mind tripping the knox 'counter'. If you follow @cruise350 advice you'll be back to Stock. then root (with SafeRoot maybe; search it's here or CF-Auto Root) you could then install a custom recovery (using GooManager or by Odining one), then flash away.
BUT you are going to trip the Knox counter by using a custom recovery.
Please spend a little (actually a lot) of time reading and understanding how things work on this phone and you'll really enjoy it and get the most out of it with as little frustration as possible.
Good luck
From the advice in this thread I was able to get back to stock ROM w/ root (CF-Auto-Root). Thanks for the tips, and for being patient.
I'm going to do some reading on Knox, because I'm getting conflicting reports on the ability to remove it.

I still can't figure out what the big deal is people have about knox. It does not effect you at all if it is tripped unless you plan on sending your phone to Samsung for warranty service. It does not prevent you from running custom roms, installing mods, or using your phone to its full functionality. It is a secure container program for corporations and government agencies that require more security for access to their networks and information. If your company is not requiring you to have a secure phone, than it means nothing. It is easily disabled or removed. The main difference in our phones after MJA firmware is Samsung made it so we can't downgrade the bootloader any more. This was so they could fully implement the knox container to prevent downgrading to older non knox bootloaders thus skirting the knox security. The warranty flag that it trips is the knox warranty flag, which purpose is to let your IT department know that you have tampered with your phone and can no longer be guaranteed to provide the secure container. It also lets Samsung know you have tampered with your phone which may violate your warranty.

True but it lock the bootloader from what I’m hearing
Hence stopping the installation of custom roms
How many times can I root and unroot my note 4? The downloadmode says 0x1 (4).
I know what 0x1 means, but what is the (4). Does it mean that I have 4 times root and unroot my phone? Can I damage my note 4 if I root and unroot often?
Hi mate, the 4 would be a counter that increases everytime you flash something. I've rooted and unrooted mine with no harm at all. Feel free to do it
it depends on what you consider being able to root and unroot.
a Samsung service rep told me you can unroot once through a Samsung service centre to keep your full warranty.
there's no limit to how often you can root and unroot your phone yourself, but unrooting your phone yourself doesn't restore (full) warranty.
as mentioned above, the counter is only there to give an indication of how many times you've modified the software, it's not going to self-destruct once it reaches a certain value.

I don't know if it's the same in the US, I live in Europe where companies have less control over terms of use and warranty limitations.
the way I understood it they will flash a stock rom to your phone and reset the counter to 0x0 if you send it to samsung once, and they will then register your serial number and deny (some) service if you send it in again with the counter at 0x1.
as far as I know in Europe companies have to provide warranty on devices with hardware defects even if the software is modified, unless the hardware defects are clearly caused by hardware or software modifications.
