Weird, since the firmware site I usually use (galaxyfirmware.com) only lists the Korean update. Are you sure it's for 12, not 11?

If so, I'll download it tomorrow, I don't have my laptop with me today.

As I said, it appears that the EUX firmware contains the XAR CSC, so I'd say go for it. If I were you, I would do a clean flash with Odin, rather than an upgrade flash that keeps data. When finished, be sure to check Settings > About to see if the XAR CSC successfully applied. I've flashed the EUX before and didn't see any obvious differences.

Edit: I won't be ready to flash it for a few days. I still have to back up my apps, their data, games, documents, etc. And my Magisk modules. I'll have to re-root the new firmware and install TWRP again, so I might as well start from scratch. I'm just not a big fan of having to redownload everything again, redo my settings. It already will take the better portion of a day to get it all set up.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Markeee:
Yeah its 12 I'm going to install now
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
I'm not convinced that it's EUX. It doesn't say that anywhere in the name. And it has the same build version as the Korean one listed at:

Galaxy Firmware SM-T970

Search again but replace EUX with KOO. See if the download URL and file name/size are exactly the same as what's in your screenshot.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Markeee:
Its good to go. I just updated didn't do a clean install didn't install any bloat ware
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
I noticed that it says OXM XAR. OXM is a multi CSC designation, I've seen it on other Samsung devices I've used. So you're good, I guess. Have you rooted it yet?

Apparently applying the patch using the latest magisk release on github did not work on my device with android 12. T875 CUCL. The tablet booted normally, but there was no preinstalled magisk manager. There are a few threads that suggest using magisk canary will work, so Ill try that. Also I think you can just patch the whole AP file, Ill try that too just to be sure. Pretty sure I did the same steps as I did before..
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
I just flashed Android 12, rooted with Magisk, and installed TWRP. All seems to be working as intended, I just need to install my apps again and configure them.

Yeah, you need canary for Android 12, I think. And no, you don't need to patch the entire AP file, that's overkill just to root.

Here's what to do. Unzip your firmware file if it isn't already. Open the AP tar.md5 file with ZArchiver. Extract the boot.img.lz4 file. Next, extract that file, you will end up with boot.img, not compressed. Install Magisk manager, patch that boot.img. Copy the resulting patched boot.img back to PC, flash with Odin. Bam, you should be rooted after rebooting back into Android, and you don't need to flash a huge modded AP file while doing so. It's that simple, that's the process I've followed every time I root my tab, works every time.

Edit: I almost forgot to say this, but after you have copied the patched img to PC, be sure to rename it to boot.img. then use a program like 7-Zip/WinRAR to create a tar file. So, it should be a boot.img file contained within a boot.tar file. The tar file can be named whatever you want, but the image within it MUST be called boot.img or it won't flash.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] SlightlyWind:
Hey, thanks for confirming. Indeed canary did work, I kinda freaked out a few times when it flashed twice without the preinstalled magisk.

Welp, I tripped Knox trying to root my S7+. I got it unlocked and rooted but tried to undo the root and screwed up my warranty. Good luck to all.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
After testing Android 12 for the past week, I'm mostly liking what I see. However, when playing Call Of Duty Mobile, my PS4 DualShock controller (genuine, not 3rd party) randomly disconnects. This happens even after I've fully charged it. It's getting really annoying, especially when it happens in the middle of a round. I've died more than a few times because of this. It was never a problem on Android 11 either.

Sometimes it will stay connected for an hour with no disconnects, other times it will disconnect several times within the span of 5-10 mins. I can always press the PS button and it will reconnect, but it's still annoying AF.

As I see it, the issue is one of 3 things:

1. Android 12

2. Faulty controller (I don't have any others to test with)

3. CODM (perhaps an update or whatever)

I've tested with other BT devices that I use frequently (earbuds, speaker, etc), they are fine and never disconnect unless they need to be charged.

I'm just wondering if anyone else is having Bluetooth issues with A12. I'm going to try downgrading to see if the issue persists.

Thanks!

Will this twrp work for t870
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
Almost certainly, no. That's a different device. I'm guessing that TWRP for Tab S7+ won't be compatible with Tab S7 (non-plus). However, I think that someone has been trying to build a working TWRP for the Tab S7. To me, TWRP is as important as root, which is why I went with the plus model.

Bought a new PS4 controller, no more disconnects. So, the old controller was aging and faulty. Looks like I'll be keeping Android 12 after all.

Anyone have the patched boot file for T870?
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
It's easier to just patch it yourself. You shouldn't use someone else's patched file, because it needs to match the version code of the firmware you currently have installed.

Download your firmware, extract using the instructions I posted on this page, patch with Magisk.

I don't know if you all noticed but there's another EUX update CVA5 out showing up on Frija

I flashed it works fine
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
CVA5 isn't showing up on galaxyfirmware.com, for either XAR or EUX. My PC stopped turning on a few weeks ago, so I have no easy way to flash it. Although I could probably call a friend and get him to loan me his spare laptop, if I really needed to use one.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Markeee:
Heres a link to it

https://samfrew.com/download/Galaxy__Tab__S7+__-Wi-Fi-__/xqvx/EUX/T970XXU2CVA5/T970OXM2CVA5/

Let me ask you a question maybe you know i can't seem to get a straight answer

What happens if your on a U1 unlocked version phone running U1 firmware and you flash your U carrier version using Home CFC so not to wipe.?

Will it still factory reset going from U1 to U and will you still get all the carrier version mess and bloatware even if you don't flash userdata ?
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
Not sure exactly what you're asking, so I can't answer. You say U and U1, but I think even the carrier firmwares would use either U1 or U2 (version 1 bootloader/version 2 bootloader). You can upgrade from U1 to U2, but you can't downgrade U2 to U1, Odin simply won't allow it and the bootloader will reject it.

As for the Home CSC thing, if that's what you flash then it shouldn't require a factory reset.

I would think that if you're flashing a carrier-branded firmware, you will still get all the bloat that comes with it. If you're not rooted, you can use a PC and ADB commands to disable the bloat you don't want. "adb pm disable" and "adb pm uninstall" are the commands you would want to use. You can also use a (paid) app on Play Store called LADB, that will essentially let you do the same thing, but not requiring a PC. It makes use of the wireless ADB debugging in Developer Options. Just Google "adb debloat" if you're interested in the specifics.

Just be very careful and very certain of what you're uninstalling/disabling if you go the ADB debloat route, since it can remove nearly *ANY* package installed, including important system apps. From which you probably won't be able to recover without flashing stock firmware. You can use an app called App Inspector to get the exact package names of what you want to remove, you'll need that for the commands.

What model of the Tab S7+ do you have?
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Markeee:
I have a T970 S7+

Unfortunately, I can't download that file from SamFrew. I started the download from the free link on that page, it says 10+ hours to finish. And I'm not going to pay them for the premium links either.

[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
Well, without a working PC, I wont be able to download it via Frija either. Besides some issues with my new PS4 controller disconnnecting semi-frequently, there's no pressing need to update right now.

I had just wanted to save it for later so I could flash it when I have a chance.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
@Markeee: I've recently found that SamFW is much faster than SamFrew. Not only does SamFrew throttle the crap out of your downloads (because they want you to pay for the premium links), but their free option to download via Google Drive doesnt even work properly. I tried in several browsers and couldnt get the download to start with that option.

SM-T970 EUX T970XXU2CVA5 alternate link

With SamFW, even the free options are fast. You can just do a regular download in the browser. Or let SamFW access your Google Drive and download that way (probably the fastest option). Just make sure your browser allows pop-up windows or the download may not start. I also recommend using an app like Hash Droid (Play Store) to compare the MD5 checksum of the downloaded file, to the value shown on the site. If they match, your download isn't corrupt.

I'll probably try flashing this within the next few days.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] googlephoneFKLenAsh:
Regarding how to update with root without losing data:

1. Use magisk to patch the extracted boot.img.

2. Flash the AP, BL, HOME_CSC with odin.

3. I have question here: do I flash the patched boot.img in odin without reboot immediately after step 2 (uncheck the auto reboot option in odin)? Or let device auto reboot with ODIN to system after step 2 and then power off and manually boot to download mode again to flash the patched boot.img?
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Ghisy:
Hi,

I know this guide is for the Tab S7 but is it applicable to the Tab S4 as well? Because the Tab S4 forums are dead and there's no up-to-date guide for rooting the latest firmware (which is Android 10).

Mine's already rooted but on an older firmware with an older Magisk version and I'd like to update everything.

Thanks guys!
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] SlightlyWind:
You can backup your boot image to a different device or upload it somewhere and try it. The method is universal afaik. If however, it fails to boot for whatever reason, you can just use odin to flash the backed up boot image

Is it possible to have another thread with updated info including all the links to the files and tools in the first thread? I find this quite overwhelming when I have to bounce around to get the info and links needed to root the S7 Plus Tab running Android 12.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
If you really want this then I suggest you create this other thread yourself. But I also think it would be overly redundant to have 2+ rooting threads.

BTW, this is the comprehensive method I use on my tab. It is exactly the same for 11 and 12 (can't say if it would be the same for 10, my tab came with 11 and no ability to downgrade). My steps will get you updated firmware, Magisk, TWRP, neutralized vbmeta, encryption disabled on the data partition. You can just skip the steps you don't want to do.

TWRP for the Samsung Galaxy Tab S7+ 5G (T976B)

[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Michael Carleone:
I agree in not having two threads; however, the initial post in this thread needs updating. Personally, I think having a sticky post/thread which is always updated either by the mods/admins, or OP would be the solution. At least, that's just my opinion.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
Well, the link I posted above works fine. It's my personal method which I've been using for months on both 11 and 12. It would probably work on 10 as well. The actual details of my method haven't really changed over the months. I feel that any Tab S7+ user should be able to follow my steps and get the same results as me. And they can just skip the steps that dont interest them. The only caveat is that I've only tested these steps with clean Android installs (wiping everything), not upgrades. I'm sure the steps would work with upgrades, but would need to be modified a bit here and there.

I can't seem to understand which TWRP to get that works for the S7 SM-T870 of which this forum is about.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] zfk110:
there is no twrp for it, this forum only for rooting without twrp

Download the firmware, and extract "boot.img.lz4" from AP.

Use 7-zip or something else to compress the boot file and choose TAR format.

Use Magisk to patch the "boot.img.tar", and you will get "magisk_patched.tar" in /Download folder.

Flash it as AP and wipe user data. (You should unlock the bootloader.)

Then you have successfully rooted your device.

How to download the firmware.

Use Samfirm to search device model and CSC code.

It seems that Sammobile has not released the firmware of the new Galaxy Tab S7 series.

@Markeee: would you mind saying how you managed to relock the bootloader? I'm unlocked but want to temp relock to test something. I can get into download mode but there is no option to relock.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
@Markeee: Forget I asked. I mistook you for someone else. Not too long ago, someone in the Tab S7(+) subforum asked how to relock. I thought it was you.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] Markeee:
Yeah I don't know much about how to lock and unlock the bootloader but a quick google search seems to bring up some how to videos
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
I know how to unlock it just fine. It's relocking that I can't figure out. Every guide I've found says to boot into download mode and select an option to relock. But I see no such option in my download mode screen. Strangely enough, volume up brightens the screen and volume down dims it, but neither works to select a seemingly invisible relock option. I can also use power + volume up, but that only exits download mode.

A user in the Tab S7(+) subforum says they managed to relock via the "bootloader menu" but didn't go into detail. The only things I know of that could be that, would be download mode. There is another interesting screen you can get to, by connecting to PC via USB, initiating an ADB connection, then typing "adb shell reboot bootloader". But this screen doesn't have a relock option either. I'm not sure what the purpose of this screen is, since it doesn't require root etc to get to it. Although I've seen screens similar to it in other devices. And my OEM unlocking in developer options is toggled on but greyed out, yet i cant toggle it off to relock.

I just downgraded from Android 12 back to 11, I was a bit dissatisfied with 12. I'm not rooted and TWRP isn't installed, just pure stock ATM. But I'm apparently still unlocked and can't figure out how to relock.
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
@Markeee: I figured out how to relock, after several hours of digging and trying different things. I'm posting a short tutorial in the Tab S7(+) bootloader unlock thread for anyone who is interested.

I had Secure Folder working perfectly on Android 11 a few months ago. This was the case even with unlocked bootloader, Magisk, TWRP, neutralized vbmeta, etc. I didnt even have to do anything special, I just signed in and it worked out of the box. I noticed others saying it wouldnt work after root etc, and tried it anyway, surprised to see that it worked.

But after upgrading to Android 12, it no longer worked under the same circumstances. It just gives a "couldnt create Secure Folder" error. So I downgraded back to Android 11 recently, only to find that SF doesnt work anymore and gives the same error I got on 12.

This was one of my reasons for downgrading, but not the only one. So I'm going to hack away and try to find a solution. In other places I've been reading, SF can be made to work even with root.

After pulling my hair out for a few hours, I finally got rooted. I'm on the latest Android version for XAR (T870XXU2CVE5 ). Odin kept failing when trying to install either the patched boot image or entire AP, but I finally noticed something that led me to fix it - I would get the unlocked bootloader message on startup but in developers options the unlock bootloader option was missing. After full reinstall, factory reset and re-enabling DE (bootloader unlock then returned enabled) I was able to obtain root.

Since I haven't seen this latest a12 version mentioned (June 2022) in this thread, here's what I used:

Files from Frija

Magisk Canary

Odin 3.14.4

Should have abbreviated it 'DO'. Enable Developer Options (via tapping the Build info 7 times) and turn on the unlock bootloader option.

Intially I had the bootloader unlock enabled, but somehow the option disappeared (yet still got the unlocked bootloader warning on bootup). After doing a full factory reset and turning Developer Options back on, I was able to do the unlock bootloader option then flash the magisk patched boot file.

Hi:

I'm going to need a new tab soon and was advised the T7+ is easier to root than T7. agree/disagree? i'll likely get the LTE/5 version. Currently have a 5e. Thanks!
[Samsung Galaxy Tab S7 / S7 Plus Guides, News, & Di] AnonVendetta:
The process for rooting them is exactly the same. But the Tab S7+ has a higher quality screen, that makes it the better bet. Things will look alot better, at the cost of slightly worse battery life. The Tab S7+ also has working TWRP builds, whereas the Tab S7 never has. People have tried to develop a custom recovery for it but encountered serious issues. TWRP may not matter to some, but it does to me. With it I can easily do useful things like installing custom GSI ROMs and backing up/restoring the data partition.

If you're willing to pay a little extra, go for the Korean version of Tab S7+, its' model is SM-T976N. I used to have an SM-T970, but sold it to a friend and bought that instead. It supports 4g and 5g, I'm using it with T-Mobile right now. It also has something that none of the other Tab S7+ models have...12GB of RAM, whereas the others have either 6 or 8GB at most. It also comes with 512GB of storage. Unfortunately the firmware's native language is Korean, but it's super easy to change it to English. Setting the language is the very 1st thing the setup wizard asks you to do when you boot it up, so you can't miss it. This model is somewhat rare though, your best bet to find it is eBay. I bought mine from a Korean seller, so I had to wait 2 weeks for shipping to the US. But it arrived new in factory sealed Samsung box, exactly as described, so I'm happy. All the stock components were included (pen, charger, cable, paper manual).
