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.

is there a way to reset Knox afterwards, so I can still use Samsung pass, and not have to deal with Knox yelling at me at boot every time?

Normally, there is no way to reset the Knox. Actually, Knox is protected by an e-fuse. When you flash customized software, the Knox will be tripped, and this is a physical damage, unless you can fix the e-fuse.

Can you still update via software update or would you end up having to flash updates manually after rooting? With regards to rooting, do you lose HDCP? On my Note 7 and Note 9 HDCP become disabled when device is custom (Apps that use it like Netflix refuse to load video due to issues with HDCP)

Download the latest firmware, and extract the "boot.img.lz4" from AP. TAR it and then patch it. Flash BL, AP and HOME_CSC. Then reboot and flash "magisk_patched.tar" as AP. You will not lose your data.
I can still watch Netflix without any problems.

OK, I'll try it when my warranty is about to end or I get really bored with my S7+.

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.

This is a good question but as I've learnt from posting a similar thread, you will only get defensive and rude answers from this forum.

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.

Is there any downgrade in widevine when rooting? Or any other issues with video resolution due to rooting?

When i flash patched file and reboot into recovery then do Wipe/Factory Reset then restart with

Power + volume up - it goes into boot loob

Only way out is Power + volume down

This way i boot system with no issues however magisk still showes not installed.

Don't power + volume up. Just re boot from odin and start magisk manager.
If you have to install magisk from there.

    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.

    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?

    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!

    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).
