Question Removing Retail Mode from S21+ - Samsung Galaxy S21+

Hi XDA, first time poster and I could not find a similar thread with the answers I was looking for, if that thread exists I apologize!
So basically I started a job in a retail phone shop a few months back. We have a drawer in store that has a bunch of old demo units in there that, once they have been removed from display, just sit there unused. There is phones in there from almost 10 years ago. They are never given back or requested back, nor are they logged in any way.
Well I noticed there was an almost perfect condition S21+ in there so I asked my manager if we could use it as a sales incentive and he replied saying the phones are useless because of the software on them. I said I was pretty sure you could remove the retail software and use it as a normal phone and he said if I can do that and get it working, I can take the phone for myself.
Well, I took it home and did some digging / experimenting. The phone has a proper IMEI already, you can put a SIM into the phone and it registers to the network. The problem is, the phone has security restrictions on data sharing and it does not have the playstore on it and there is no factory data reset option in the settings, nor in recovery mode.
I have tried flashing a stock firmware on using Odin which I thought worked, however when the phone restarts and you go through set up, Samsung Knox pops up and installs settings which forces the phone to set up in retail mode again with the same restrictions as previous (no play store, factory reset etc).
Any idea how to get around this issue? I would have thought flashing stock software would be the obvious work around but something on the phone forces it to install on retail mode every time.
Any advice on this is much appreciated.

Have you tried following the steps in a video such as this?
DO THIS COMPLETELY AT YOUR OWN RISK! I AM NOT RESPONSIBLE IF ANYTHING GOES WRONG, INCLUDING BUT NOT LIMITED TO BRICKING YOUR DEVICE, GETTING A VIRUS OR STARTING A LITERAL WAR.
Everything i was able find on the subject was kind of sketchy-looking (probably because doing this without permission would probably be illegal) so I included a warning.

Thanks for the reply!
So I also came across this same video on the subject last night, it seems to be a workaround for bypassing Knox but I couldnt find any further info on what kind of state that leaves the phone in after, if it can still get official updates and such or if it triggered to eFuse that causes you to lose access to Samsung Pay and other official apps.
I'm aware this is at my own risk, the phone will sit in a drawer if I cant figure it out any way so no harm no foul as far as I can see. I've thought about rooting the device (I know this will trigger the eFuse) but I cant find any info on if that would get around the specific issue I'm having of Knox forcing the phone to install in retail settings or not so do not want to go down that road just yet.

I'd say that the Knox workaround would probably (do not quote me on that) leave you with un-tripped Knox (=e-fuse intact) if it even still is. Even if Knox would be tripped, you would still most likely be able to get software updates. But because you said that you have already used Odin successfully on the device, that would lead me to believe that OEM unlocking might already be on in which case there probably isn't any more to lose by rooting the device. On a rooted device there are instructions o WikiHow on how to remove the Knox , but I haven't personally tested them. If I were you, I'd check with a Knox warranty checker app or through recovery mode, etc
whether the e-fuse is already triggered before continuing with anything.
And if I confused you, feel free to ask anything!

With the root approach you would also have to worry about passing Safety Net, but that'll only be relevant if you decide to go with that path.

Interesting, I may give the workaround a shot when I get home later then.
So I have used Odin but it was with official firmware obtained through Frija and, according to reading, that does NOT trip the eFuse. I did turn on OHD in dev options but from what I can tell, the fuse is only tripped when you load an unofficial image onto the device which I havent done yet. I can check when I get home by booting into recovery mode and checking the warranty line AFAIK it will say either 1 or 0 indicating if it's been tripped or not.
So my issue with rooting is I dont know if I root, will the phone still install in the retail setup that it does currently. I know I can run apps or code to remove Knox once rooted, but I dont know if then just reinstall firmware and it will be back to default like I want, or if I'll then need to figure out how to get the playstore loaded, if the security issues persist etc. Also as far as I can tell to root, I need to install Magisk on the device first to alter one of the image files, then move that file back to the PC to flash with Odin, and I'm not sure I can do that with the retail settings enabled.

So quick update on this: none of the workaround videos on youtube seem to be capable of doing anything. They all rely on being able to connect to Wifi then get around the device before Knox settings apply, however on my build as SOON as you connect to wifi, it immediately starts applying knox settings and cannot be skipped.
I am wondering if this is because the version of software I flashed on using Odin was the most recent firmware, being android 12, and most of these workarounds are for android 11? Is it safe to locate the original firmware for the S21+ somewhere and flash that on to the device instead do you think?
Also the eFuse is still currently in tact.

You could flash an older Android version, but if and only if it has the same bootloader version as the current one, otherwise it won't work and might even brick your device. I am unsure though if the downgrade would help but if the bootloader versions match, you can try!
On SamMobile.com you can see older versions of firmware. Just check the bootloader version before flashing!

It's most likely as simple as comparing the bootloader filenames between the Odin flashable files for the old and new software. I could verify whether that's the case if you send the filenames for both bootloader files here. (The file that goes into the BL slot in Odin)

So the first image is of the current firmware that successfully flashed to my device via Odin.
The second is firmware from August 2021 that is on a build of Android 11. You can also see by the file modification dates.

SM-G996B
Region is Ireland (CSC is MET)

Yeah, it seems like the current bootloader is version 4 while the Android 11 one is version 3 so these versions seem, unfortunately, incompatible.

Hi there, I can help you out! I have some experience with Samsung.
So first off, I take it this is an Exynos model? Snapdragons require the use of a paid service to get an unlock.
It seems you've flashed stock firmware before but it didn't work out due to Knox. Did you flash all the files including the CSC (wipe all data) file? Also, you could try flashing TWRP and that would trip Knox, at which point Knox is disabled due to detecting system modifications or it will try to rollback your modifications.

So the only thing I personally can think of to get rid of the problem is going the TWRP route, but this will trip the Knox warranty byte to 0x1, so think about it. There might be someone more experienced than me that might be able to help without tripping Knox, but this is right now the only thing I can personally suggest to fix the problem.
Edit: It seems like someone more experienced appeared while I was writing this! Sweet!

Are you able to enable developer options? If so, you might be able to use ADB commands to disable the Retail Mode app. I doubt they're enabled though.

With official firmware, I'd be pretty certain that you can't. By the way, please look at the latest messages as there is someone else with fresh ideas here, too.

Is there a fix for this error yet?

S8 plus stuck in recovery with following message:
"Support SINGLE-SKU
Supported API: 3
dm-verity error
failed code : 0x02"
Is there a fix for this yet?
cheers
Matt
...? Elaborate?
What did you flash that lead to this?
dm-verity is what you usually get when you flash something incompatible, or when some insecure fw image is rejected.
Reflash the firmware using ODIN, and the latest FW package for your model / region. (in the AP box)
If you end up with DRK error afterwards, then you're boned. You need Samsung to help you out.
TL;DR: Careful when flashing stuff next time, always verify what you're flashing is for your device's model.
OP, did you found a solution to your problem? i'm asking because now i have the exact same problem as you do so i would really appreciate if you could tell me what you've done.

Took it back to Samsung and had to pay them £290 to fit a brand new board.
Out of warranty coz i rooted it.
only way out.
Gutted.

Guess the problem was that you didn't flash dm-verity bypass when u tried to root.

Wrong.
I did flash it, and it was rooted for about a week, but for some reason, i was bored, just potching around with my phone and decided to uncheck 'allow OEM' unlock, but forgot to re-check it before i restarted the phone...too late though...as Samsungs awesome security basically said...NO WAY...he's tinkering about with root triggered the efuse on the board and the ONLY way to fix that was a brand new board.
I'm not a newbie (hence my 371 thanks meter) when it comes to rooting phones....i've been on here since 2011 and rooted stacks of phones....HTC HD2, HTC Sensation, Desire HD, LG G2, LG G3, LG G4, HTC One-X, HTC One-x Plus, HTC Desire eye and a LOT more...Just made a silly mistake a week AFTER I rooted the phone.
I gotta be hnonest, I thought i'd miss root, but can hand on heart say....i'm not missing it one single bit.
My lovely Samsung still has 20 months warranty and i'm keeping it that way by not rooting.
LOVE my S8 Plus and to be honest, with Knox etc....I'd advise everyone not to root this EXPENSIVE beast of a phone!:good:
Matt
In some countries (like the EU ones) it is legal to modify the software on your phone, without voiding HW warranty, so if ur phone dies, and they can't prove that it is because the modification, they have to replace / repair it.

WRONG!
Hardware problems -> YES
Problems due to wrong use of your phone (i.e. root and phone won't do anything anymore): NO
And I do agree with Samsung: if you temper with the FW, and your phone doesn't do anything anymore -> IT'S YOUR OWN F...... FAULT ! ! !
Here's the nice big fat bill I got for repairing it.
Eeeuuurrreekkaaaaaa!
So after being presented with this error due to my own stupidity (trying to diagnose why MTP wasn't working on windows 10 and disabling Developer Options and not re-enabling OEM Unlock), I managed to get around it quite simply although at the cost of my data... BUT at least its not bricked.
The solution is simple;
1. Use SamFirm and download the latest firmware
2. Using Odin Load all the firmware options (BL, AP, CP and CSC) and in the options tab select all the checkboxes except "Flash Lock" and "T-Flash".
3. Press start and hold your breath.
Upon completion the phone may not reboot automatically so you will have to manually reboot using the Bixby, Volume Down and Power Buttons. Once rebooted you'll see it erasing the remaining userdata and finalising the re-partitioning process but a few minutes later you'll see the samsung logo and the welcome screen.
I hope this helps someone. Good Luck Peeps
I have the same problem guys but my odin isn't working the ID thing specifically the computer isn't recognising the phone.

Can't Downgrade samsung system app

the samsung device maintenance system app worked alright in the past, but I've been seeing a few people not liking the new update since it apparently targets more than what it should; I aimed to not update it at all, but while I was updating apps before I went to sleep yesterday, that app updated as well. I didn't know it did so I've been trying to downgrade it to an earlier version. I downloaded an apk file from apkmirror, made sure to uninstall the updates to it and set it to factory version, but it won't let me install, saying it conflicts with the same app already present. I then used the adb command-line tool to "uninstall" it (pm uninstall -k --user 0 com.samsung.android.lool ), hoping it would work then, but it says "nope, this app doesn't exist on this phone, plus this apk file is corrupted". I can "re-install" it by installing it from the google play store
I'm at a loss on how I can get this done without root (I don't plan on rooting my phone unless the situation is perfect for it), using the adb tool or any tool that won't kill my phone. Any help

Uninstalling updates and reverting it back to the factory version is downgrading it as far as it will downgrade, and if it worked before you let it update, then you are running the version (factory) that was working previously, therefore something else is wrong if it still doesn't work

Flash the same ROM over the top using HOME_CSC instead of CSC so not to lose data
If that fails, bite the bullet and factory reset

im using the default Android OS (7.1 nougat), no custom ROMs, and this android phone was bought at an AT&T retailer; if the right chance comes, I would be willing to flash a custom rom (probably LineageOS) after I get it unlocked (doubt ill be updating to a newer phone unless there's an actual difference) and the money situation is good, but until then, sticking with what I got
I did remember about an application called odin that can (maybe?) flash stock rom of android without tripping the knox counter, that true? and if I do, will I lose all my installed stuff, apps, contact info, etc...

If your phone is a US model S7 (snapdragon) you cannot flash custom ROMs
My instructions are for ODIN (version 3.12.7 for Nougat)
So at this point, my only option is to switch to a new phone that can be used by Odin, or just standard root my phone and flash a custom rom of a different type, right?

You cannot flash a custom ROM to a snapdragon phone using any method, it has a locked bootloader
ODIN is for stock ROMs only (and TWRP recovery which you cannot use on snapdragon either)
You can use ODIN on any S7 for stock ROMs
To sum it all up, you're saying that I have to get an exynos/international version of any Android phone if I want to root and or flash a custom ROM, correct? And if I do, could I still use it with a US phone carrier, like AT&T or MetroPCS afterwards?
And even if I could use it with a US phone carrier, would I still be eligible for any technical support / repair service they would offer, or would I have to use a non-affiliated repair service?

Yes, only Exynos has an unlocked bootloader (See the snapdragon vs exynos custom ROM dev forums)
Yes you could still use a US carrier as long as the phone is SIM unlocked (carphone warehouse phones are all unlocked), I have no idea of the limitations / implications, but some people here already do that, and the G930W8 (Canada) is Exynos
No idea about warranty, but if you bought it from say the UK and had it shipped, you'd have to discuss with Samsung if they would accept it into a US service centre or if you'd have to ship it back to the UK, no idea about that, no doubt there are places in the US that you could buy a Exynos from

Tripped knox is forever. There is a fuse that blows on the phone. That said, there are workarounds on rooted phones (you might as well stay rooted). Try looking for edits for the build.prop to restore functionality to Samsung Health and other affected apps. Dr Ketan still makes ROMs I believe and should have something for you.

Then I won't root. The only reason I want to root is because I need to use mod apps like Spotify but sadly all the ones v been downloading never worked. Can you help me out please. Thank you

I don't want to be rude, but your question was answered already. You can't untrip the know counter. It's an actual fuse, that physically becomes blown. This isn't a software setting, but an actual, physical fuse.
It goes back to the days of people using exploits, and in rare cases would damage their phone in the process, but the phone worked enough to relock the bootloader. Then the person would send their phone back and blame it on the manufacturer. So now Samsung decided to put in an actual fuse so that if you decide to unlock it, your warrenty is permanently void.
Bottom line, your out of luck. I know any unlock would have given a warning that it is PERMANENT and that it would VOID YOUR WARRENTY. Wether you read it and ignored the warning, or didn't bother to read it, it's on you for unlocking your bootloader.

Yea I remember those days... Well truth is I haven't rooted.. I was considering it until I read the warranty part... My point is, the reason I want it rooted is because I want to use some modded applications. I researched further and found out I could use some without even rooting. So i tried downloading Spotify mod app, but unfortunately it didn't work. I couldn't get recent application for it, what I kept getting was an outdated mod app. In all it didn't work. So am asking if there's a way to use mod apps without rooting the phone. Thank you

You'll have to wait until someone mods the latest app. Or, you could just pay for Spotify. For the record, I used to use a modded Spotify, and they typically patch within a day or two of a modded apk being released. They may have finally switched to server side authentication which is why your likely not seeing an updated version. I stopped bothering because it's just a cat and mouse game. I didn't feel like Spotify was worth it, so I moved on.
I find Google Play Music is a better deal. I get add-free YouTube, and all the same music as Spotify, for the same price.
On a side note, I don't believe Xda allows modded apks that bypass paid features. There are sites that cater to such things, but I'm pretty sure it's a no-no here. They tend to support devs / companies as opposed to cheating them out of money.

Hi, you can flash the U1 firmware on the Sprint 965U. You need to use the patched Odin linked in the OP. The CSC file included is for multiple carriers. When flashing it will read your sim and setup accordingly.
Umm what's new? The "I" September patch Odin's have been out since mid September.

The thread provides detailed instructions and the most current firmware. The instructions are new to the thread and so are the links. Didn't realize I was required to explain what was new to you.
Uploading G965USQS3ARIB firmware now.
Hi, Q. If I install the ARIB version in my U1 under att, I still can use another carrier sim right?
I'm traveling to Argentina soon and I want to know that.
Thanks
Should be fine , your U1 is unlocked. The sim card in Argentina might not set up the APN for you regardless of what firmware you're on. Personally, I would use the U1 firmware though.

I don't use the "B" revision firmwares, but there was at least one listed as a BOYD firmware. Since your already on U1 and loosing wifi-calling, HD voice, volte, etc, that might give you the best luck. Might be something to look into.

You asked about sim swapping for traveling. The BYOD firmware makes for easier sim swapping. It's designed to populate the carrier settings when you insert a sim instead of needing to wipe your device.
As for ATT features, I believe those firmware are for the U firmware, so yes, you'd regain those features, but you'd get the ATT bloat. I don't mind the bloat personally. I just remove the junk I don't need.

samsung galaxy s7 custom binary blocked by frp lock

Greetings, ever since i tried rooting my phone, i knew something went wrong (i used cf autoroot).
So the first thing i noticed, i was asked to reset the phone or something similar to that, meaning i would lose all my data.
I tried to find a workaround as this had never happened to me before while rooting a phone, and someone had said that i was supposed to download twrp
and change some partition and then change it back. I dont remember what else he mentioned and what exactly i tried doing, i realised it was formatted either way and i had to start fresh. As i setup my phone i went and switched the oem unlock back to "off", as i did not wanna attempt to root again, but i hadn't realised that my phone was infact rooted sucessfully, leading me to my first error after restarting. "Custom binary blocked by frp lock", with absolutely no access to recovery mode at all anymore. Again, trying to find a workaround, i download some stockfirmware that i atleast had hoped was the right one for my phone, after a couple failed attempts of flashing with odin, ( i had gotten various different error messeges on download mode screen such as (REV Check fail device 7 binary 0 and others witch i cannot remember), now im getting a new error screen, stating that an error has occured while updating the device software. I cant flash twrp recovery as the frp lock is on, and the only thing i can guess is that im flashing the wrong firmware, but i cant find a matching code at all.
Its the following: sm-g930fzkadbt
IMEI: 35214310282955
on the back of the phone it says uk yateley, although the phone was purchased in germany.
Im not sure what to do anymore, any advice would be greatly appreciated.
PS: I have managed to get back to the old error screen with the custom binary info, this time with bootloop, by checking the deviceinfo box on odin
Yep you've now learned the hard way not to mess about and read the proper guides.
Anyway "dbt" is just unbranded german firmware. Download UK "BTU" and flash with Odin, it's UK unbranded.
FRP lock means you'll need to unlock the phone with the google account and password that was on it before you started messing about with it.
If you don't know the google email and password you need to read up on how to bypass FRP lock and it's a nightmare.

Thanks for your reply, just a question, will any btu update work? Should i download latest android version btu firmware?
(Also yes, it was stupid of me to try and do it quick but i had rooted 3 different samsung galaxy phones in the past without issues, either i did something wrong or it took something way too specific to do the job, perhaps the phone's unrootable, but thank you either way) :fingers-crossed:

You'll likely only find the last version of BTU think it was August 2019. It isn't updated officially anymore but it'll be fine to use.

OK so i thought it worked but i can only enter recovery mode now and download mode, but cant actually boot the system, it just boots up the battery screen whenever i plug the charger, and never shows the actual battery info, just the thunder icon. Formatting from recovery mode doesn't help either (Note whenever i launch recovery mode it says installing update, then says no command and brings me to the recovery menu) Any ideas?
PS: It fixed itself. Sorry for the pointless edit.

It doesn't matter, Verizon devices have locked bootloaders that can't be unlocked, don't waste your time trying, it isn't going to happen. Verizon devices have been this way for years now, I don't forsee that changing at any time in the future.

You can try it but I'm pretty certain that Verizon has it locked down. There is a root method for Verizon S7 and S7 edge but no TWRP or custom ROMs that I know of.

It might depend on what version/build number of stock firmware is installed on the device. That guide might be for an older version of a specific version. If what you have is newer than what the guide was written for, that might be why it failed.
Does it say anything in the guide thread about it requiring a specific stock firmware or specific bootloader version?

I've gone through a couple different tutorials and they all seem to link to the same files that I need to download. It's been frustrating because looking for proper files for a phone this old leads to a lot of dead links. I'm probably going to give it up soon, but you know how it is. There's always "one more thing" to try. I tell you, I'm going to research like hell before I buy another phone. I need to know for sure that it can be rooted. In this case, I inherited my wife's old phone and a quick search revealed that it ought to be a piece of cake to root. There's always some little detail that trips me up. I appreciate your help with this.

Try a version of Odin from around the same time the S7/S7 edge was released onto the market. Some versions work better with certain devices, as android evolved and as Odin gets updated to newer versions for newer devices, there are slight differences along the way that can effect how it works on older devices.
If the stock firmware that you are trying to flash is older than what was already installed on the device, it will probably fail due to not allowing the device to be degraded to an older version, it's a "security" measure put there to prevent you from installing a less "secure" operating system.

No, I mean does it say anything about it requiring a specific version of stock firmware or specific version of bootloader to be already installed on the device "before" you do the rooting process described in the guide?
Sometimes these kinds of things require your device to have a certain stock software version as a starting point before the device is modified. Most of the time, if the device is ever updated to a newer version, the specific exploit that was being used to root gets patched in the update, killing the effectiveness of the exploit used to root. From that point on, chances of rooting are nil.

Yeah, I've been careful to download files in keeping with my specific phone, not just the G930V but the longer version of that model number, which seems super specific. Nothing works. I've tried three or four different versions of Odin at this point, but they all either fail or get stuck somewhere in the process. Probably time to start searching for a new phone. I looked around for other ways to root this s7 but i'm not finding much. I rooted the PIxel with Magisk.

I'm not talking about model number version, I mean the specific build number of the firmware that is installed on the device. Some guides/methods only work on specific build numbers of stock firmware or only work if a specific version of bootloader is installed on the device.

The S7 *can* be rooted, with lots of limitations afterwards. It just can't be BL unlocked
It could be failing due to the usb port or cable. I have an S8 that i can no longer flash only because I don't have a usb port in my pc old enough to flash it. I assume the S7 is the same way
