Galaxy S6- Knox Warranty Void 1 (0x0400)

[HELP] Knox Warranty Void tripped while flashing official stock ROM
Hello, just bought a new Galaxy S6 with SFR France firmware. Downloaded and installed my country firmware (Romania) to get rid of SFR bloat. flashed via Odin (Knox was 0), reboot to recovery then it showed error dm-variety failed or something like that. I wiped system and cache, reboot again, waited and configured the settings and just to be sure I rebooted the phone in Odin mode and it showed Knox Warranty Void 1 (0x0400). why did that happened? Didn't try to root or install custom firmware, only official stock firmware from sammobile. anything I can do in this case?

Pray that somebody comes up with a workaround or reset (and nobody will notice it on warranty claim). Similiar thing happened to men since then I use custom ROMs.

I hope someone comes with a solution for this. I'll pay for it. Hate it because it happened to me.

What does that code stand for anyway? (0x0400) is it something like an error code or something?

really? flashing through odin up the knox?? that's new, at least to me...

Yes. no root, no custom ROMs/kernel/recovery. I only needed a stock official ROM with no carrier bloat whatsoever. and this is what happened.

there has to be something wrong, i had a galaxy S4, and i flashed many stock roms and it never upped the knox....can someone more professional explain or confirm that? because i was planning to flash a stock rom through odin to get the latest update....

Every time I install the stock firmware KNOX stays 0x0.
The only time I install the stock firmware is when my phone is in a bootloop.
It works every time--no issues whatsoever.
Odin should be the safest program in the world.

yeah, that's weird, did you try it on your S6? thanks

I can't post pictures yet so I can show to you. After flashing the ROM, reboot to recovery to perform system wipe..at the bottom of the screen where normally it shows applying the CSC, instead it wrote something like "dm-variety failed". Wiped, reboot to write the new firmware, check odin mode and there it was: Knox Warranty Void 1 (0x0400)

I actually own the galaxy s6 edge. I have tried it and have never once gotten a single issue.

No fix for this at all?

There is no fix at this moment for sure. I also flashed ROM(ania) and other stock roms and never had problems, maybe accidentally you tried to flash the carrier romania rom, not the stock one.
Anyway, there isn't anything you can do at this moment, but at least you can install some custom roms and make this phone fly.

http://www.sammobile.com/firmwares/download/54541/G920FXXU2COH2_G920FOXX2COH2_ROM/ this is the ROM I flashed. it's not my first time flashing with Odin. had the S4, Note 3 and Note 4, never had problems while flashing official stock ROMs.

Weird, i saw some people also saying that they triped knox flashing stock roms. I don't really know the technical details about s6 but my only ideea is that your SFR rom had a different partition scheme(usually carrier roms have different PIT files) and installing a stock rom which also has a different partition scheme and maybe that''s what triggered the knox. I bought mine directly unlocked from emag and i can freely flash stock roms.
Your phone was locked and then unlocked via code or you bought it directly unlocked?

Phone was locked and unlocked via code. I use it on Digi Mobil network.

If I flash the SFR rom back, will it do something to the knox flag?

Which will never come, since the Knox counter is an eFuse, so once it is set to 0X1, then only Samsung can set it back to 0 (probably by replacing HW or the mainboard).

Yes I had the Verizon Nougat bata installed. then I simply used odin 12.3 and flashed this firmware like any other stock rom.
When you flash it, your phone user data will be wiped. So I recommend you to make a backup of your files, apps and stuff first

Now we need root for 7.0. I'm gonna stick to 6.0.1 U firmware until then, but I'll be checking daily.

@Tetraguy - THANKS!! I downloaded that 2.3GB file in 4 minutes via Google Drive share as opposed to Sam Mobile people keep referencing. We should get this on Android Files site too!

TOP 5 Solid Reasons Nougat is improved over Marsh:
1) Direct Boot
2) File-based Encryption
3) Number blocking/call screening
4) Faster, Refined, Optimized over Marsh
5) Notifications: redesigned, bundled and Quick Reply-able
#3: Number Blocking/Call Screening! DEATH to RoboCalls!
Android 7.0 features an advanced number blocking and call screening platform that provides users with complete control over unwanted callers and unknown numbers. Carrier integration also means numbers you’ve blocked through the dialer can be blocked via all mediums, including VOIP and call forwarding. Number blocking can also block texts and allow multiple apps to use the blocked numbers list for more system-wide blocking support.

I apologize for the noobish question, but I have the latest unlocked firmware ending with APL4(smg935u). To get this, do I just download the file and flash everything through odin? Do I have to flash just parts of the file( like just the ap/cp) or do I flash everything( BL/AP/CP/CSC) The last time I tried to flash tmobile firmware onto my unlocked, I kept getting issues. Been trying to figure this out all morning, but still a little confused. Any help will be greatly appreciated

I believe you can just flash without any prep work (aside from backing up your data, of course). To my knowledge, most of the G935 firmwares are interchangeable in that even if you get stuck you can always flash your stock ROM again. I'm on AT&T running Tmo MM just fine. All I had to do was update APN afterward so it could talk with the AT&T network. As I understand it, per the above post you can flash the "HOME CSC" to avoid data deletion. I would still backup whatever you can via adb or whatever program you favor.

Thanks for this. I have all the files loaded up in Odin but haven't hit the button yet. I have a G935U. Do you know if there is anything that prevents downgrading back to 6.0.1, since that's where my stock firmware currently is? And also, it's safe to flash the bottloader and all the rest, to my G935U? Thx!

That, I don't know; going back. I'll leave it up to a more seasoned veteran to answer the question about the bootloader version. My understanding is that the G935U is identical in terms of the hardware it has and the software it runs (sans bloatware from carriers), so in my mind it doesn't seem like you'd have to worry about it failing.

[Q] Can we Downgrade SM-G930FD from 7.0 to 6.1 ????????

Can we downgrade SM-G930FD from 7.0 to 6.1. dual sim india model exynos.
not rooted ever
stock rom
bootloader locked.
if i simply flash 6.1 firmware from odin will it brick my device as i guess bootloaders are different in 7 and 6.

When you flash with Odin you should be flashing 4 files (AP, BL, CP, CSC) one of which is the bootloader (BL). So long as you download the correct BL for MM6.1 it should be fine.

Is downgrade possible ? i read somewhere that we cant downgrade because of the new locked bootloader. can some experienced person shed light on this ?

That might be true for the US models, but the 930F and 930FD bootloaders are unlockable.
Also correct me if I'm wrong, but flashing stock firmware is meant to work even if the bootloader is locked. It's only custom firmware that should be a problem.

Can confirm this works, did it like a week ago on my SM-G930F.
Just be sure to flash AP,BL,CP and CSC, as @Beanvee7 mentioned

Am pretty sure, but you will lose your files as you cant take the home_csc to downgrade (I believe??). Why not just try? Backup your stuff and in worst case just flash the 7.0 back.

G930FD can use G930F firmware, I have successfully flashed from 7.0 to 6.0.1 a couple of times on my G930F
You will need to use CSC not HOME_CSC as nothing from 7.0 will work with 6.0.1 and you'll either bootloop or get lots of app crashes on boot

You made this thread 2 weeks ago, you could have tested it yourself many times by now
Either try it or don't

If you flash all 4 files you should have no issues.
Issues like you described are when people change android version using TWRP flashing ROM's, then they end up with bootloader mismatches etc.
That can't happen to you because you're cleanly flashing all 4 firmware files to a matching version.

All the information is already here on XDA S7 forums many times over in many different threads, if you read some threads
No need for multiple ? either, we can see one just fine

Use the latest odin, there's a full update guide on updato.com with a link to the latest version of odin

i am back on 6.0.1 on december build.
but feels bit laggy and battery drain alot android OS.
is there any better version that i can flash rather than december build.
when i got the new device my mobile was fast and good battery life.
my device is manufactured of july 2016 so i guess the firmware must be pre installed of earlier than july.
so is there any firmware 6.0.1 which is faster than other build or is it a myth only ?

The differences between months would mostly be security updates, I doubt there is any major under the hood changes that would impact performance. Did you phone come with carrier bloat originally? Could be that you just need to debloat.

Thanks. Will post if I find a solution.
T Mo and Samsung are not playing nice. I was able to completely remove the T Mo app with the Samsung A21, but no luck with the A32 5G (using ADB). Also removed over 200 junk apps from the A32 5G. My goal was to get it as bare-bone as the A21. Yet the A32 still pull about 1.3 GB of RAM vs. 930 MB for the A21, with the major difference being Android 11 vs. Android 10. Apparently, the claim about better memory management in Android 11 does not pan out in actual use. The Android 6 in my ZTE V8 Pro is lightning fast compared to Android 11.
Most people are not aware of the tremendous amount of spyware that are hidden on these Samsung phones (Amazon, Microsoft, etc). The OS is free, but informed users should have the option to easily remove these junk apps with a few keystrokes.

You can't downgrade once you've upgraded

wouldnt there be a way through twrp or brom mode?

Nope you can try brom mode but i dont trust if works
If you buy a samsung device depending of the device (like this A12 and the MTK imei bug) is not a good idea to upgrade

That's samsung for you, once you've upgraded Binary version there's no going back.
As for the brom mode, samsung has locked their phones out of that mode. I don't know if accessing it through access points works but you could try to see if it can help

I tryed to downgrade via TWRP flashing baseband and BL
Now my A12 is DEAD and i dont had a box to repair it (after flash i see the security error screen and flashed again the Binary 3 BL once odin tell me passed the phone doesn't booted again)
I just wanted to get the imei working because the firmware on the binary 3 (11 and 12) android system uses all my ram memory trying to get the signal working
F*** *** Samsung and mediatek next time i bought an exynos or qualcomm variant

The last rom that i used on my A12 was pixel experience and worked perfectly on binary 3 android 11 based firmare (A125MUBUS3BVF1) just installed TWRP with nulled vbmeta flashed the image as system (not as super) and wiped the data (not advanced wipe) rebooted and the gsi was booted (only bugs mentionated on the thread and the touch bug)

How'd you do it?
Technically since I've always known that I can't access brom on my samsung I've never tried to understand what you can do with it.

I was only planning yo use the brom mode to use the MTK META Utility which is developed by Mediatek themselves for fixing imei to see if I can fix the imei issue with it but I couldn't enter brom mode and I'm afraid of opening the back cover

its relatively easy tbh. just be careful around the volume buttons, but everything else is okay. there arent too many cables to rip

Its easy to open but be careful with the power/fingerprint sensor flex i think the testpoint is near of the charger flex in the mainboard (i see youtube tutorials to access to Brom mode and preloader)

Hello,
If you're going to be performing a downgrade, you'll have to have the SCATTAR firmware with all of the old loaded certificates and tokens. Flash is going to be performed via BROOM (fused ROM code) useing SP_FLASH_TOOL.
Regarding the IMEI issue, that I'm not able to help with. And it is pain to work with, maybe you the MODEM file could help bout dbout it. You might have to go diging through firmware sites.
Thats it.
Stay safe,
Krypton.

SM-A125U Multitool Kit (Root/TWRP/Unlock/Unbrick)
Here is a toolkit of several tools ive collected and put together for the A12 in a single pack to help see through all the clutter and chaos of this forum, i have an A125U (converterd to a-125w) so thats all i can confirm working 100% but im 99%...

Maybe this can help you only you need to download a firmware (don't try to flash a binary 2 or binary 1 firmware if you do that you phone will get a hardbrick and the sp flashtool will give the 0xC0020029 or the anti roolback error)
Pd: dont forget to change the date to 25/05/2022 to get the mtkmetatool working

You generate it your self

To unlock bootloader on these the easiest way is to convert it to an a125w xac by flashing the a125w bl files. Unlock bootloader with seccfg. Then flash ap, cp, and csc from a125w with odin and when it boots up it should show as a125w. Also in download mode it shows the same. My imei says unknown but i believe thats caused by unlocking bootloader so if you relock it after converting it should go back to normal. Playing with mtk modem tool to rewrite imei. Tried using xposed imei changer but didnt seem effective.
