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.
Its good to go. I just updated didn't do a clean install didn't install any bloat ware

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..

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.

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!

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.
Bro video pls we are very ignorant.

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.

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

    The various mileage from people rooting in this forum offers super conflicting information, especially conflicting with the OP.

    Can somebody who knows what they're doing, please make an actual guide that is longer than 5 short lines of general info, with links to files and explaining why he picked what thing to do / downmload, and then also please explain:
    - what do you loose by rooting? knox? netflix widevine L1? dex? pen? bootloader unlocked (how)? anything else asked on here and here?
    - how do you update after rooting? (without re-flashing everything every time)

    There's another quick guide in this thread, but no replies and no explanation for why he did what, so again not an actual guide that inspires confidence.
    Knox is 100% tripped. Samsung Pass cannot use. Netflix widevine, Dex and Spen are not affected.

    Unlock Bootloader: turn on "OEM unlocking" in "Developer options"
    connect to the PC, reboot the tablet and hold both volume up and down. Then hold volume up to unlock it. (The method may be different now)

    Download the firmware from Frija and unzip it.
    Unzip the AP file, you will get "boot.img.lz4" and tar this file, get a tar file.
    Copy it to your phone and use magisk to patch it, get "magisk_patched.tar" in "/Download". Copy it to the PC.
    Whether your phone is rooted or not is not important.

    Boot into Download Mode, and use Odin flash AP, BL, CSC, (CP). Then use AP slot flash "magisk_patched.tar".
    Install magisk manager on your tablet.
    Done.

    When updating your tablet, you should reflash it, including the new patched file, but use the "HOME_CSC" file instead of "CSC" file.
    Data will not be lost.

    Why patch the boot file?
    When patching it, magisk is written into it. When you boot your tablet, magisk will run. Another way is to patch the recovery file. When boot into recovery, magisk will run.

    When updating, why flash "HOME_CSC"?
    Flash "HOME_CSC" you will keep all your data, if you flash "CSC", you will lose all your data. It is the easiest way to update it.

    Any way to fix the Knox?
    No.

    I know this is a question that might be better suited for its own thread but I kinda think its a quick answer for you guys.

    What do you gain from root on this specific device? I haven't had to root a device in a few years since Android has gotten pretty dammed good for my use case, but what's there to be had from rooting a tablet?

    I'm looking forward to my Tab S7+ but if I can make it better with root then I'd love to do it.

    I have rooted my Tab S7+ what i gained is the ability to add a system wide ad block with adguard doh + firewall with the ability to use a vpn at the same time.

    Also bouncer now works seamlessly with a rooted device. I also use warden which blocks in app trackers and loggers from system apps and debloat easily from the device without using adb.

    I am able to use tasker to seamlessly adjust apps that are not optimized for tablets in landscape mode so that they work properly on my device.

    All of that is only possible with a rooted device and im discovering new tweaks every single day.

    1) The firmware I've downloaded doesn't have a 'CP' to flash (I think that's just the modem?).
    2) Do I need that?
    3) It has AP, BL, CSC and HOME_CSC only. Is it because I have the wifi-only version?
    1) Correct
    2) No
    3) Yes

    Anyone updated to one ui 3.1??
    Yes, currently running 3.1 on my Tab S7+ (SM-T970). Rooting also went well, no issues so far
