Hello all, I've got a AT&T S4 sgh-i337 with the locked mk2 bootloader. Bought new, still under warranty (well.. supposedly
I'm trying to go back to bone stock to return it; I think I did because when going into odin download mode, I see the following:
PRODUCT NAME: SGH-I337
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
KNOX KERNEL LOCK: 0x0
KNOX WARRANTY VOID: 0x0
CSB-CONFIG-LSB: 0x30
WRITE PROTECTION: Enable
eMMC BURST MODE enabled
I did lots of reading and found some info I don't completely understand (go figure haha). I read that even when the S4 does not DISPLAY the binary counter, said counter is still there and reviewed when the phones are returned.
My 2 questions are...
1) if the custom binary counter is indeed there, is there an adb shell command I can run to READ the counter?
2) if the binary counter is there and I need to reset it... will the triangle away method work with my locked (and "unlockable" mk2 bootloader? -- under supported devices for triangle away, I see "Samsung Galaxy S4 AT&T SGH-I337 UNLOCK BOOTLOADER".. I'm afraid they meant to say "UNLOCKED" bootloader... in which case, I'd be out of luck.
Thanks a bunch!

No one knows? any info or guidance? Thanks
The following is just my opinion.
Both Samsung and AT&T offer a 1 year warranty on the Galaxy S IV phones. Since you are on MK2, I would guess your phone is at least 1-1/2 years old, so any worry about the warranty is pointless, since the phone is no longer under warranty.
You want to return the phone to AT&T? If that is the case (you don't state where) then the likelihood of anyone checking any of the counters is extremely unlikely, let alone any hidden counter, if it exists.
In my opinion, I wouldn't worry about it. Just flash it back to full stock, whichever version you can put your hands on, and you'll be fine.

Thank you very much for taking the time to reply creepyncrawly! Much appreciated.
I was going to return it to Samsung as I bought it refurbished at BB a couple months back.. I believe they honor the 1hr warranty on factory refurb phones (but I might be wrong)
Anywho.. I kept working on it, testing new stuff, different stuff and finally was able to get everything working nicely by forcing it to take the I337UCUFNB1 upgrade.
Thank you again, cheers!

Hello everyone,
I have been trying to find an explanation for this but was not able to anywhere. Here is my problem, I had rooted my AT&T Galaxy S4 SGH-I337 and played with it for a few days flashing different kinds of ROM and trying all kinds of cool stuff. But then I decided to bring it back to stock. I unrooted and did everything including resetting the binary counter and the phone seems perfect and like new but accept for one problem. When I go to download mode I still get the famous yellow triangle but everything else looks right as follows:
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
KNOX KERNEL LOCK: 0X0
KNOX WARRANTY VOID: 0X0
CSB-CONFIG-LSB: 0x30
The question here is, is the yellow triangle in my case a normal thing to see or something went wrong with the unrooting process. If the yellow triangle is not supposed to be there then I am hoping someone would put me on the right track to get rid of it. Thanks in advance.

I believe the yellow triangle is just there to let you know download mode is serious business. Your system status and current binary report offical, so I wouldn't worry about it.

Good news. Thanks.
Can someone with the same phone confirm that please.
I've made a bit of a mess and I need help please. My s4 is softbricked, but as softbricks go, it's rather hard.
I have an early S4 i9505 bought from Carphone Warehouse (UK, unlocked, pre knox). I rooted it, installed TBackup, greenify and got it how I wanted it. Then I downloaded a stock firmware from Sammobile and tested to see if I could get it back to 'warranty' condition, which was a success.
Confident that I could obtain warranty if I needed it, I re-rooted it, installed TB and greenify, and it ran sweetly for months from that point onwards.
I read about the arrival of updates (and knox) and concluded I didn't need them. It was working, leave it alone.
Then out of the blue, my nice stable machine broke. I didn't change anything I was aware of to cause it.
No normal boot.
No recovery.
Download only.
Using Odin, I tried allsorts, eventually getting the same Sammobile firmware to run.
2 days later, it broke again, same as before, but worse!?
Then I tried all sorts of stuff downloading no end of things trying to get it to boot or even go into recovery. The most promising approach was to reload the firmware along with a .pit file, but still no joy. I've lost track of the other things I tried, but I've been doing it for a week, so a lot has been done. In desperation, I even tried downloading the latest firmware, so I now have signs of knox of the odin page.
I now have the following symptoms:
Booting into recovery brings up the blue 'booting recovery' message then just blackness.
Normal boot is exactly the same as above.
Unpowered conection to my laptop gives a 5 second boot loop featuring the buzz only.
I can reliably boot into download and download stuff with Odin and change the little Odin page status messages. After (foolishly) trying the latest firmware, these messages say
ODIN MODE

Please can anyone give me some advice on what else I could try?
Thanks

If anything else is not working (especially, if you're unable to go to recovery) I'd call sammy service center. Your download mode says that you did not rooted your phone, and knox is untouched either.

Thanks for looking spamtrash.
I was wondering if I could get away with that. It does look good from the Odin display, but the flash counter must have a pretty high number in it by now! Won't that show up somewhere?
Do you think it does actually have a fault on it, rather than just some software that's messed up and needs tweaking?
Thanks

1. Are you able to go to recovery mode?
2. Assuming that your previous communicates were taken from the screen in download mode - you're clean.
If answer for 1 is: NO, and assuming 2: do not bother the flash counter. Flash counter does not means you messed with custom ROMs, it just means amount of the ROM update tries. As they are unable to prove that the counter was not increased by failed KIES updates, you're safe.
To go deeper, service will have to flash and wipe your phone.
One thing: remove your sd card prior to giving/sending it out.
Try a different usb cable.I was in same boat as you (after stupidly thinking mobile odin pro liked modems).
Luckily I had an unused cable off my tab 3.
It's a long story. My note 3 was rooted and knox 0x1, then got a gyroscope sensor problem, sent it to repair. The service centre in west field (London) wouldn't repair because of 0x1, I tried another (carphone warehouse, Samsung's authorized repair provider) with the same result. So I called this number UK - 0330 SAMSUNG (726 7864) on their UK web site. They arranged a service request and sent me an prepaid envelop to me (I didn't mention it's rooted or anything just pretend to be innocent). I got the envelop in couple of days and sent the phone to them (could be their head office service centre or something but I am not sure). They repaired it and sent it back. I checked the knox was still 0x1. Never mind if I can use it.
But in couple of days, my phone developed another problem, which was the wifi couldn't be turned on. So sent it to repair again. Got it last Friday and the problem solved. More interestingly, knox is 0x0! I checked IMEI, it's the same as before, except with IMEI SV 01 after the original IMEI. I am not sure it's the hardware replaced or a software update.

this is normal.
Samsung got their own way to revert back the knox. Happened few times earlier to other users as well.
anyway knox is their creation, they sure have a way to deknox.
Sent from somewhere under the sky, at the corner of this rounded earth.
so samsung is lying to us that it cant be reset

They aren't lying. They can reset it, we can't
Sent from my SM-N9005 beast of a phone.
Something in the boatloader file .bl
When it was repaired was it out of the box firmware?
Okay then... If I'm right we CAN reset Knox Warranty Void back to 0x0. Just depents which version of Note 3 you are using. Didn't someone leak a file to reset Knox on some Exynos Note 3??
SAMSUNG has AUTHORITY
Samsung authorized service center can put back Original IMEI when they replace Mother board, New Mother Board will Replace 0x1 to 0x0.
Can't someone just come up with a way to feed false info to whatever part of the software that checks the efuse?
Essentially not really "resetting" knox but lying to it. Making it read "0" even though it's "1"
Or hell, likely even easier, making the display show "0" regardless of the info

My thought exactly.
They changed a piece of hardware and the put the original IMEI bsck.
I think "Phone info" a market app (and I guess other too) can backup IMEIs.
I'm surprised environmentalist aren't on Samsung/Qualcomms ass for using eFuse, its honestly is a waste of resources!
My samsung S8 can't return Knox 0x0
It must be something in the bootloader because I was digging through the aboot.mbn on the SM-T350 stock firmware (with a hex editor) and found WARRANTY VOID: 0x%x (%d) If I change that to WARRANTY VOID: 0x0 (0) and flash it with Odin wouldn't it show 0x0 (0)?
Why not try?
It happens to me but in my case all sensors stopped working they changed my motherboard and my imei remain same

I did and it Failed with Secure Check Fail: aboot
The closest we are right now is masking the value to 0x0 with MagiskHide, and then using the Edxposed module "Firefds kit" to get 'Official' system status, however; this only works in the system and it will still say 0x1 in download mode.
It is really hard to modify the bootloader to make it show 0x0 because if you try to flash a modified bootloader with Odin you will always get the error
"Secure Check Fail: aboot"
As far as actually resetting the eFUSE or in other words making the "real" value 0x0 (After already being tripped to 0x1) is impossible because it blows/trips a phisical fuse.
So, basically to reset the counter we have to somehow modify download mode to make it show 0x0 and then use MagiskHide and Firefds kit to get 0x0 (In the system) and Official system status.
I want to start off by saying that I kept digging my own grave because I'm stubborn. I have looked and tried everything and will try again after posting. There are messages and phone calls that I need to get to for college and this has really made me a bit stressed/ depressed.
I recently got an S4 SGH-I337 from AT&T and upgraded to 4.4.2 KitKat. I decided to root it and flash a rom (first phone I ever decided to flash a rom on, bad decision on my part). Everything was fine and dandy until I decided to install TWRP Recovery, it then killed all access to the recovery menu. I was still able to get into the phone via download menu (removing battery). I then decided to factory reset everything. I followed all the steps and images down to the letter.
I tried this: http://forum.xda-developers.com/showthread.php?t=2502003 (Fails on Odin, every single time)
Afterwards, I would get the message: "Firmware upgrade encountered an issue..." (Kies does NOT work since it doesn't even appear on the list when I hit emergency recovery. I even tried Firmware Upgrade.)
Then I used this on Odin: http://forum.xda-developers.com/showthread.php?t=2404970
It worked but it gave me the message "System software not authorized by AT&T has been found on your phone." I decided to download and use this: http://forum.xda-developers.com/showthread.php?p=49687770 due to him solving his issue (http://forum.xda-developers.com/showpost.php?p=52837496&postcount=203)... It voided my warranty and is back to "Firmware upgrade encountered an issue..." Still cannot use Kies as nothing shows up when I hit emergency recovery. What voided my warranty was a stock image.
Kies and Odin don't work. I have no idea what to do. I'm honestly scared to tell my dad and way too stubborn to actually tell him about it. Hahaha. Since I voided the warranty, I really have no idea how much AT&T will charge, I don't want him wasting money. All my money sadly went to school. These are the files that I accumulated during my googling: http://puu.sh/ayQwm/e8d232b4b0.jpg

If there are info you need, I'll do what I can to tell you. Note, I can't get into my phone, but what I can do is get into Odin mode... I appreciate it if you can help, I'm very new to this.
*I do NOT know what the 4.4.2 version is, so I have no power over that. I didn't memorize it at all and am just going by what the Box says: I337UCUAMF3

I found it earlier and downloaded the NB1 Rom. It worked. Thanks for helping though. I'll find the thank you button somewhere. :good:
Hi.
I can't find answer to this. I know that triangle away delete the number of installed custom roms but does they have any way to check that i had custom roms? I know the issues with samsung and warranty policy so i want to be sure that i can fight back if they refuse to fix my phone because of knox. (overheating) If they do this, this will be my last samsung phone.
Triangle Away worked when all the S4 had was the flash counter, but it doesn't do anything when it comes to the Knox flag. Once the Knox flag is tripped by installing a custom recovery, it stays tripped. There is no way to reset it. So Samsung has an easy way to check.
If warranty is a concern, there are ways to root that do not trip the flag. However, you're stuck with Touchwiz.

Oh i know it (i used to change firmware on old sony ericsson phones). I can lie about the knox since some people get it changed by samsung tools, thats why im asking if they have any other way than knox, like under bootloader. My phone is overheating because of hardware problem, i want to be prepared for service reject (stories about rejecting repair of defective screen etc.).
They might not even check the flash counter. You can give it a shot. The worst that might happen is that they send it back (Unless they repair it without consulting with you and charge you for it).
My phone also gets pretty hot when playing games and the phone is charging at the same time. It burns my finger if I keep it in one place, literally.
I guess that's how they intended it to work..
@VanHelsing091: I misunderstood your question. Sorry about that. As GDReaper points out, they may not even check for a tripped Knox flag. If they don't, there's really no way we know of that they can tell if the device has had a custom ROM flashed.
@GDReaper
But mine is getting 50 degrees on main screen, watching photos etc. over 65 while doing anything else, over 70 while charge and using chrome even on locked cpu clocks under 1300mhz.
@Strephon Alkhalikoi
Thanks. If they refuse to repair my phone on warranty because of knox - that will be a lie (damaging phone by custom rom... sure, without touching OC in kernel tools), so i wanted to be sure if i can lie too about phone history, it happened before triggering knox anyway.
Im hoping for the best and good service, if not then i may start one of those big posts about company vs user. Thanks again.
