So I bought this i537 used a while back, the previous owned never registered it with samsung but I did when I bought it so I do have a warranty on it. I know it was previously rooted then unrooted before I bought it but I don't know if it ever had a custom rom on it. I rooted the phone with activeroot (still on 4.2.2 stock rom) and have since unrooted it with superSU.
I am having problems with the touchscreen and samsung has confirmed warranty coverage and gave me a shipping label but I want to be totally sure it a-ok before I send it in.
When I boot into odin mode there is no KNOX status, is that normal for this device? Did 4.2.2 not come with knox on this device?
Also the status says custom? When the phone WAS rooted it said official ??? seems bass ackwards.
Also, I would like to reload stock 4.2.2 via ODIN just to make sure everything is kosher before sending it it, would this void my warranty?
My phone is also sim unlocked, i imagine this is okay as far as warranty goes? Would reflashing with ODIN break my sim unlock?
Thanks so much!

Let's start from the top:
This phone came with MF2 (4.2.2), which was then immediately updated to MF3 (4.2.2). Both of these versions came with Knox enabled. If he just rooted then he probably didn't trip the Knox flag, but there could have been other things he did or tried to do that did trip the flag.
If it is indeed the i537, I can guarantee he did not flash a custom ROM. The i537 has a locked bootloader which means no custom recovery and no custom ROMs. However there is the ability to use TouchWiz-based ROMs, if you want to learn more about this and how it works read about SafeStrap.
We do not have official 4.2.2 stock firmware available to flash. We have a pre-release of 4.2.2, a pre-release of 4.3, official 4.3, and an OTA to go from 4.3 to 4.4.2. You can read more about the different firmwares in the i537 Firmware Thread.
Flashing firmware with Odin will erase your SIM unlock, but you can either enter the unlock code again or there are other methods that can be used. I'm not familiar with SIM unlocking so you'll have to do a little searching.
You never mentioned what you're sending the phone in for. I would try flashing the MF1 firmware first to see if it's a software issue. If it's a hardware issue then unfortunately you'll have to send it in.

Thank you for the quick response. I edited the first post to add more details but you must've already quoted me before I hit send.
Basically the problem is the screen will randomly detect 1, 3 or 5 nonexistent touches across the center of the screen (confirmed by enabling "show touches" in the developer options). While this is happening the touchscreen becomes unusable, rebooting several times will eventually fix it but the problem comes back randomly, sometime within a couple minutes and sometimes after several hours.
I did confirm my device is running MF3 and it is absolutely a i537. I'm using the phone on straight talk not ATT so I have not received any OTA updates beyond this point.
So,anyhow I understand I can fix the device status:custom with triangleaway but I don't understand why there is no KNOX counter in ODIN mode and how this may effect my warranty.
Also, if I did ODIN to 4.3 or 4.4 would this trip the knox counter? (Assuming it isnt tripped already).
Thanks for your input, truly appreciated!

It sounds like it might be a software issue so it would be worth it to try to flash the official 4.3 firmware. Flashing official firmware shouldn't trip the Know flag, but I'm not really an expert on Knox. I have read that Knox being tripped doesn't affect warranty repairs.

Thanks, I went ahead and flashed 4.3 via ODIN and the KNOX status is showing 0x0 so that is a good sign. Has only been about a half hour so I cant say whether or not the touchscreen issue is fixed yet but I will post back and update what happens after a day or so.
Another plus is the update finally got rid of that god awful default font on 4.2 (changing the system font wouldn't change the fontface for plain text in the browser).
Quick update in case anyone is having a similar problem with "phantom touches" in the future.
After flashing to 4.3 the touchscreen problems have continued so i do believe it is a hardware problem that will require disassembly to fix.
Also the phone keeps trying to download the OTA update to 4.4 but I've heard bad things about the update so far so I've left my wifi turned off.
Going to be stuck using a windows 8 phone for a week or while my phone is out for warranty repair.
There is an app in the play store called phone info. There it tells you your knox status without root or being in download mode.
Sent from my SAMSUNG-SGH-I537 using xda app-developers app
One final update in case anybody runs into similar problems in the future. Samsung confirmed it was a hardware problem and fixed the phone 100% free of charge under warranty.
It appears they replaced everything which is pretty awesome because I now have a brand new digitizer and bezel without a single scratch or scuff on them. Also my usb port cover flap was feeling pretty worn/sloppy so now thats new and even the USB port itself looks brand new which tells me the motherboard was replaced. I can tell they peeled the old serial/IMEI sticker off the old phone and stuck it on this one.
Surprisingly they didn't update it to 4.4 while it was there which kind of sucks because I'm nervous about doing it myself after reading horror stories on the forums.
Anyway I'm very pleased with Samsung's support!
Hi,
Few months ago I've upgraded my 9305 to 4.3 and rooted it without a problem (and disabled KNOX)
Bulid: JSS15JI9305XXUEML8
BASEBAND:I9305XXUEMK1
KERNEL:3.0.31-2051278 [email protected]#1
Todat, I have returned to factory default, but this time I could not perform any root: Using ODIN 3.07/3.09 and CF-Auto-Root-m3-m3zh-gti9305, as well as Kingo, did not help.
Rooting process was fine and the device has restarted, but the phone was not rooted and KNOX cannot be removed
I've tried it several times, while all rooting process were reported by odin as "success" but actually, nothing.
Please advice. I'm nearly desperate...
Thanx

Hey don't know whether this might help as i am total noob but i am trying to catch up with it all. but with all the reading i have been doing to root i9305 i think this might be the best way.

Good luck
Have you tried flashing a recovery and installing SuperSU

Hi, long time lurker, been on hiatus for a bit since knox came in, but looking at trying to root my current phone.
Can I ask where and how you manage to disable KNOX? I've got 4.3 with KNOX after sending in my phone for warranty repair, and didn't wish to accidently screw things up messing with KNOX.
If you can point me to the right direction so I can disable KNOX it would be awesome. as my current stock rom is crap.
Cheers,

He means disabling the Knox security features I believe. Supersu does this automatically after installing and activating it.
To the best of my knowledge I still dont think anyone has found a way to disable the Knox flag in the Booltloader. So if you already have stock Samsung 4.3 on the phone, then you will get a Knox warranty void flag if you mod it.
^ Thanks for the clarification. I totally thought I missed something... lol.
I searched and found nothing exactly like what I was experiencing and nothing I hadn't already tried. Hopefully someone has seen this before. I HAD a nice rooted stock SM-G900A 4.4.4 and now I have a flashy gold brick (soft). I rooted by downgrading the kernel to use towelroot then flashed stock kernel back. Everything worked fine for about a week or so. I'm not sure at what point I started having issues exactly so I'm not sure if an app or mild mod could have caused my issues. The only thing I had done was use SuperSU to block Knox and change the terrible TW stock sounds to standard ogg clicks and what not. The trouble started with the camera. I opened my camera and the screen would flash green then I would have red ghost images in a pattern on the screen. The pictures I took had the same effect when viewed in the gallery. If I switched modes the problem would go away with the camera until I closed then opened the camera app again so I assumed it was a software rather than hardware problem. I couldn't find any info on a fix so I did a factory reset. The problem persisted. I decided finally to flash back to stock. That's when it really got bad. After flashing to stock the phone will boot to the Samsung animation with the swoosh, freeze there for a few seconds without completing the boot animation then the screen shuts off and the phone becomes unresponsive. The only signs of life is the blue LED is constant lit. I have to do a battery pull to start over. I have flashed just the PDA and I have flashed the whole shootin match (except for BL) and I get the same results. I have tried stock tar files from a couple different sources. It will go into download mode as well as stock recovery where I tried a factory reset after flashing. PLEASE HELP!
So I flashed OA1 stock kernel and got it to boot. Of course now I get the Update interrupted message when I try for the OTA to anything newer than the 4.4.2 it's running. And after 8 hours of messing with this gem the camera issue persists.

Go here and flash back to NCE. Then take the OTAs.

That is what I ended up doing just an hour before your reply and all is well again. I suppose my first attempt to go back to NCE didn't work because I didn't use the downgrade flash, just a regular 4.4.2 stock. There must be a difference between the two. The OTAs still wouldn't work so I ended up installing the updates from external sd. The lollipop OTA is downloading fine though. Thanks for confirming I FINALLY went the right route. This root screw up wasn't as bad as my last (efs S3 debacle) but it still took too many hours to fix.

If you take the 5.0 ota you won't be able to root. Just FYI. There is no root for it yet. There is a pay however in the general section on how to upgrade to 5.0 and keep root.
Hi all!!
After spending a huge amount of hours, searching the forum, I still have doubts...
Is it possible to downgrade from Lollipop, to kitkat, without tripping knox (warranty void) in the S5???
Some say, that flashing with Odin it's ok, others say that will go in a loopboot, others say that the bootloader is not compatible, and flashing a new rom will trip knox, others say that if the rom is official, will not trip knox...
What to believe??????
If there is a way to downgrade, safely and without tripping knox, please show me how, in a step-by-step process, I really appreciate it.
Here are the mobile phone data:
SM-G900F
Firmware: G900FXXU1BOD3
Thanks in advance!
Downgrade away, I have the G900F, and flashing KK over LP works fine and does not trip KNOX
You only trip KNOX by flashing custom stuff, stock ROMs are signed by Samsung so do not trip KNOX
The only issue I had was having to flash KK twice, first flash worked but wouldn't boot, flashed again, booted first time

Hi Detection!
Thank you for your enlightement, but tell me, you flashed your device using Odin, right?
Thanks!
Yep, ODIN 3.10.6

And how did it go?? Did You safely downgraded to KK?? I was thinking about it, got my S5 with pre-installed Lollipop but without root I can't block adds and stuff - it's rather annoying.

You can root lollipop, but it'll trip KNOX
CF Auto Root
Yeah i know that CF-AutoRoot works on lolly but I'd rather keep my warranty void Guess no new method on gaining root w/o tripping knox was introduced to S5 design If i recall S6 is rootable now without knox messed up but no go for S5
I flashed my S5 a few months ago from 5.0 back to 4.4.2, and last week the same thing, but on my gf's Note3.
It's kind of easy and safe to do, if you do some research in advance:
- find exactly which ROM you need (the wrong one won't work and make ur phone temporarily unusable).
- download the official stock ROM
- KNOX won't trip if it's an official stock ROM.
- Boot the phone in recovery mode to wipe the cache partition and do a factory reset (after backing up the important data).
- Flash with Odin. There's many youtube tutorials on that one.
Enjoy.
If you didn't do a factory reset, wipe cache partitions etc you'll almost certainly get stuck in bootloop after flashing. In that boot up in recovery mode again, do those wipes and then restart.

Hi all!
Tell me something, after flashing KK, software update is allways trying to update to LP... is there a way of avoiding this, without root access?
Thanks in advance!
you need to disable the FOTA processes, but I'm not sure you can do that without root
Ok guys so let me get this straight - I only need proper KK image, provided by Samsung (their signature and so on) with my CSC (in my case Polish XEO)? Then connect my phone with PC, start ODIN (any particular version?) and what to choose, what check and what not? Sorry for this only had HTC before (and Sony and LG but those are wifes phones) and flashing on it was a bliss, especially when You had S-OFF.

Not stop, but you can delay it indefinitely by clearing the cache in recovery each time it has the update ready for you to install
Then boot back into droid, and hit the install button, which will fail because you just deleted the update in recovery
Rinse and repeat
You can root KK without tripping KNOX though, so no reason to not root it really

Either make sure your KK ROM is a pre June 2014 build, if not, either flash with ODIN, or read up on how to downgrade only the Kernel to a pre June 2014 KK kernel, then use towelroot app to root it, and flash your original Kernel back
All the info you need is here on XDA, might take a bit of reading, but you should really learn as much as you can before blindly flashing things anyway
I read in another thread, someone said that if your S5 came with LP out of the box, you can't downgrade to even official samsung KK without tripping knox. I'm not sure how true is this or whether that person is just blowing smoke.
Got phone at launch, rooted for awhile, bricked with custom rom. Didn't realize how much a pain in the a%^ samsung became went back to stock and left it, but tripped knox, have tried clicking software update occasionally since then, but nothing ever happens. I'm still on COF6. Does tripping knox completely kill updates? It does nothing after clicking update, thanks.
I was rooted and went back to stock and was able to update. The latest is OJ7.

Was your Knox tripped though?
Yes, several times over too because i screwed up rooting the first time and had to try again, and then i tried all the roms out while rooted. I went back to stock specifically to try to the OJ7 update when it came out.
