So, what is userdata?
A lot of people think this is carrier bloat only. However, userdata also contains the files necessary to activate carrier specific features. Without it, you may not be able utilize all of the carrier features that the phone is capable of providing. Please note that carrier userdata may not be available for your carrier.

I v just one question. How do I restore a tripped knox after flashing or restore my flash count to zero?

Got a non-Android File host mirror? They're slow or not working for me at all no matter what mirror of theirs I choose.

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 I couldn't get recent application for it, what I kept getting was an outdated mod app.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 dude, I have 2 questions, I just buy S9+ 965U sprint unlock running U3ARH7 can I flash this 965U1's fw? and What is CSC in U1 fw? thanks

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.

[HOW TO] Carrier Switch Galaxy S8/S8+ **SNAPDRAGON**

*READ FIRST*
This thread is now completely dedicated to the aspect of Carrier Switching on the Snapdragon model of the Galaxy S8/S8+, the current root progress can be seen here:
Current ROOT Progress for G950U/G955U Snapdragon
Please Note that if your device is network locked this WILL NOT unlock it for use on other carriers, however it will allow the switching of carriers and carrier specific features on network unlocked devices just by changing sim cards, the device will reboot and your done. As for those with a network locked device this thread still applies to you, if you are interested in a bloat free experience(that is faster and smoother than stock touchwiz), on your Galaxy S8/S8+​
Let's Begin!
Download the firmware for the unlocked S8/S8+ here:
G950U1UE1AQDC_XAA
Download the Prince Cosmy version of Odin here:
Odin_3.12.3_Modified
Enable developer options on your device:
Settings----->About Phone----->Click Build Number 7 times
Enable USB Debugging:
Settings----->Developer Options-----USB Debugging
Put your device into download mode: Volume Down + Bixby + Power
(accept the warning and connect your device to your computer)
Take the G950U1.zip you downloaded in step 1 and extract it, then place the BL,AP,CP,and CSC files into their corresponding places within Odin and press start
Once finished the device will boot back up and you will be free to disconnect it from your computer
You now have the unlocked, bloat free, firmware on your S8/S8+

My build number is SM-G950A and my firmware is G950USQU1AQD9. I am quite familiar with the concept and process of rooting but I have never had an opportunity to actually get into it. I was wondering if my device is compatible with this firmware. If so I am fine with testing so long as there is a reliable way to restore my phone if something were to happen.

I went ahead and did the favors of doing some testing, in terms of restoral anyhow. From my experience, you do not have access to the usual desktop, and you have very few apps by default(none actually, just settings). I was able to revert to the original stock firmware via odin without a hitch. I did not try installing TWRP on this firmware however, but I can confirm the existence of OEM Unlock, which, by itself, claims to unlock the bootloader.

This is compatible with your device all US versions of the S8 and S8+ have the same model number. I have your stock firmware i just need to upload it to androidfilehost
If anyone feels like it joining I have created an IRC room we can all chat in and brainstorm things. It's #sgs8 on irc.freenode.net. Hasn't had many users since I created it but I lurk in there when I'm at home. I'd love some company. Let's get this thing rooted so we can shut all the haters up!
Glad to see more devs working on this

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

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
Hit Samsung up on twitter and ask them

SM-G930A 6.0.1 unlocked running on T-Mobile flash to SM-G930T 8.0?

Hey guys,
My dad has a SM-G930A 6.0.1 unlocked running on T-Mobile. It is starting to show it's age (battery drain, apps not running like they should, etc.) and is still stuck on 6.0.1.. From my understanding, it should be possible to flash to SM-G930T, however I am a bit lost as to where to begin the process to do so. I tired going straight to 8.0 by flashing the SM-G930T 8.0 firmware files but this didn't work (I didn't think it would work, but it was worth a try). With that said, would it be better for me to just stick to updating to SM-G930A 7.0 via the guides posted, or is there a way for me to Flash the SM-930T 8.0 firmware? Thanks in advance.

Wow you guys really get screwed over there in the US with cell phones. It's a pain in the a** to do anything with your phones.
Anyway I'm guessing the phone was originally AT&T right? And now it's unlocked to any carrier.
If you just want to update the phone to the latest firmware then just flash AT&T Oreo. It won't affect the SIM it will still work as before.
If you want to flash any other firmware including T Mobile then you'll need to unlock the bootloader on the device and that's a whole different ball game. With plenty of guides on how to online.
Make sure you back up all the things you want to keep before flashing

Thanks for the reply! I appreciate the direction. You are right, US phones are a pain. And yes, the phone was originally an AT&T phone, but was unlocked.
As for unlocking the bootloader, I've found different sources that say that unlocking the bootloader on this particular phone is not possible with this particular phone. I did read something about an engineering bootloader being used to get around a locked bootloader for rooting. Could this be used for flashing as well?

That's not entirely true. Using Odin you can flash any USA firmware onto any other USA device, no bootloader unlocking required.
It's very common for people to flash G930U over their G930V/T/A/P devices to remove bloatware

It's unstable and only lets the device charge up to 80%, your best bet woulld just be a full flash with Odin
This guide is a bit dated but it's the best one out there. Just make sure you google the latest Odin and use all 4 firmware files when flashing https://updato.com/how-to/how-to-install-an-official-samsung-stock-firmware-using-odin

That's not entirely true. Using Odin you can flash any USA firmware onto any other USA device, no bootloader unlocking required.
It's very common for people to flash G930U over their G930V/T/A/P devices to remove bloatware

Thanks for the reply! I had tried flashing the 8.0 G930T variant last night with the latest version of Odin and the PrinceComsy version and got a Model Mismatch error. I read that the modified Odin3 v3.13.1_3B_PatcheD would let me flash the firmware and ignore the Model Mismatch error. However, I didn't go through with it because I was not sure if I would brick my phone and instead erred on the side of caution and made my post here. Would I be safe to flash the files from SM-G930T_1_20180625111401_xf3965l42p_fac onto my current device?
If your firmware files are from a trusted source like sammobile, updato or samfirmtool then it should be fine
Odin3 v3.13.1_3B_PatcheD seems to have positive feedback here on XDA so should be fine too https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572

Greetings-
I apologize for jumping in an already created thread, but I think I am in the same situation, and like to verify with you both before I use the advice please. I have a SM-G930T that I just purchased, and really like to run a custom rom. But I understand I can not because I have Android 8 on it. I know how to use Odin, and have the latest version plus you guys talked about it here. I have also already downloaded the stock rom from sammobile site. What are my options? Is there a rom I can flash the phone with using Odin that would provide better performance, less G..bage, and more battery life? Is there a way for me to root the phone? I really need an app that requires the phone to be rooted.
Thanks

Ok, so flash any unbranded Stock Rom for your device using this version of Odin which has been specifically modified to flash US devices. https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572 PatcheD.zip is the file you want to download.
Then when you have checked the phone is working ok on undrnaded firmware you can go ahead and root the device using this method which is again for US Qualcomm devices. https://www.****************/2018/0...on-galaxy-s7-and-s7-edge-on-android-8-0-oreo/
Take you time and read instructions.

Can I get unbranded stock firmware from sammobile? I understand the generic meaning of it, but I need more information on how to get them and what I need to know to work with them.

If I understand it correctly there is no unbranded firmware for the US, its all network specific but you can flash unbranded UK firmware and it will work fine, UK BTU is the one you want from sammobile.
Load into the modified version of Odin and flash.
This is what I found, and downloading.

Yes that's the right one but like the beanvee and i have said there is a specific way to flash this stock then root the device.
You also need Samsung USB drivers installed so your pc can talk to your device, there's plenty of guides around how to flash with Odin and what you need to do beforehand, the only difference with you is the version of Odin your using and then the method of rooting afterwards.

Thanks. I have used Odin before, and I already downloaded the patchD version of Odin from the link. Thank you so much. I'll keep you posted on how it turns out. I still do not have a verified version of a custom recovery for this. Do you guys know of any? I found this link but the link to the suggested twrp does not work. I think it is this one. But I can not be sure. The original link points to a slightly different url.

Nope do not use that TWRP, it will flash TWRP but not boot it and you'll be stuck on Samsung logo forever.
There is still no way to unlock a Qualcomm snapdragon bootloader and i'm not sure anyone is working on it anymore.
All it means is you need to flash custom Roms via Odin or possibly the inbuilt S7 recovery, you just need to check the ROM is in a format which can be flashed that way.
With regards to finding a TWRP solution you'll have to do some serious searching on google and read everything.
There are already several de-bloated stock Roms on the forum if thats what you want to do. Root and custom recovery TWRP are two different things though, you get rooted so your good to go?

Yes root is my main goal, and you are right the debloated roms will work just fine. I can do w/o twrp. Just double checking here; since I am flashing the UK rom, and I believe one of the comments on this thread was how US images are locked tighter, would not I be able to find a UK version of TWRP for my phone? Just checking.

Now pull up a chair and listen closely.....99% of the American devices (including yours) have an extremely uncooperative Qualcommm Snapdragon cpu at it's heart and thus refuses point blank to play ball. The online community have done a fantastic job creating the modifications you are now using. The rest of the world (i'm happy to say) enjoy the S7 with an extreamly cooperative Exynos cpu at it's heart. It just loves to be fiddled with, it's a whore of a chip, constantly on the go with all kinds of neat tricks.
Anyhoo... my point is, the software has to be compatible with the hardware you catch my drift? All the cool little programs are written with a specific piece of hardware in mind, unfortunately for you guys Qualcomm is the ice queen.

Thank you so much. You guys are amazingly patient, and informative. Thank you for educating me, and helping me achieve my goal.
I have tried a few times but can not flash the files. I have attached screenshots, and followed the instructions here. Do you see anything I should be doing differently?
I initially thought the code came as one tar file, which I could flash, but it was a zip file, which I had to unpack.

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.

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.

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

Question Removing Retail Mode from 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 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.

I am interested in how this develops. Please keep me updated with the warranty byte status and whether the workaround is successful!

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!

So this may seem like a dumb question but how do I check to make sure the bootloader version matches?

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.
What were your exact model and region again? Probably won't matter, please wait a minute

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.

Dammit, so it seems I'm stuck on Android 12 and there is no way to get back to a previous version then I take it?

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.
