Hey everyone,

UPDATE: WORKS WITH ANDROID 12!! You can now use the more stable verison!!

Thanks to the people at github, yujincheng08 , updated one of the github commits and was finally able to root this device.

How to unlock:
Should be the same as any other samsung device. Follow my S6 Lite guide.


How to root:
1. Download the firmware for your your tablet, i dont know if i can link the sites but you can google it. (frija is recommended and is the fastest)
2. Extract only the AP portion of the firmware.
3. Open up the AP portion with 7-zip or winrar
4. extract the boot.img.lz4 out of the AP file
5. Download Lz4 https://github.com/lz4/lz4/releases to your pc corresponding version.
6. Extract the LZ4 to the same area where the boot.img.lz4 is
7. Open command prompt in that folder and then do
Code:
lz4 boot.img.lz4 boot.img
8. Download this magisk version from github
9. Extract the app-release.apk
10.. Connect your tablet and put it in your downloads folder
11. Install it via th My Files or use a file explorer.
12. Move the boot.img into the tablet and use the magiks that you just installed and patch it using that .
13. Move the magisk_patched version back to your pc, rename it to boot.img and create a tar version of it (i used 7-zip)
14. Open up odin , put your device to download mode and then patch the AP using the boot.tar you just created.
15. It should reboot, wait a few seconds and it may reboot a couple times. Then it may ask you to factory reset and just reset.
16. Once you setup your tablet again, connect your pc and do all that usb setup agagin and then move that app-release.apk again.
17. Youre gonna have to install the app-release again but uninstall the magisk already installed on your device first then install it via the apk
18. It should say additional setup required so do that, reboot and you should have root!

Thanks for the notice. Just rooted my device successfully using the latest Magisk build from the master branch. Works great!

@ahrmakrm1235 The github artifacts link will only work if you are logged into Github (create a new account if need to, it is free).

first time rooter here. do you mind specifying what you mean by opening command prompt in the folder? i extracted the contents of the Lz4 application into the folder containing the boot file. when I open command prompt, i drag that folder there and then enter the code, but it's not doing anything.

Use 7zip zs, free and works just like 7zip , easier method than the lz4 extract.

@Flaccthehawk I'm going to try it out now and see if it makes a difference. If not, I'll edit and add pictures or a screen recording of what I'm doing wrong.

Edit: I did everything correctly, but I'm having trouble flashing the tar file. It keeps failing. I've already tried updating to the latest odin version of 3.14 & I know the firmware is correct because I downloaded it using frija. Any suggestions? I've attached what the error looks like below and my tablet in download mode in case there's an issue there.

In step 13 when creating the tar file for the boot image, what did you use for this? Did you use 7-zip? And did you select the tar option in the archive option in 7-zip (or another program)? Note that it must be a proper tar file. If the file created is a zip or 7z file, it won't work even if you rename the output file as a tar file.

Can you open the tar file using 7zip. Provide a screenshot of what is displayed here. Also within 7-zip after opening the tar file, click into File - Properties and provide a screenshot of this also.

FYI: I actually removed root for now. I noticed the battery was draining a lot quicker than before with Magisk (I did a clean format/flash too when rooting the device). Removing root, battery life is back to normal.

Yes, the bootloader needs to be unlocked. Note that the device will be erased when unlocking the bootloader so backup any data that you need before doing so.

Hi again, I have problem about SafetyNet test failed (basicIntegrity -, ctsProfile -, evalType BASIC), also I cannot enable MagiskHide (after I enable and back to Magisk home, it's change back to disable). Does it possible to bypass SafetyNet test and enable MagiskHide?

Many Thanks :)

@zriw It wasn't clear from the screenshots, but for the file patched by Magisk, did you rename this to boot.img? Once the file is named as boot.img, then you create the tar file as boot.img.7z. Now you should be to flash it again using Odin.

@imjizho It looks like you are not using a recent version of Magisk, as MagiskHide doesn't exist anymore. On the latest release, Zygisk needs to be enabled and then you can enforce and configure the DenyList.

For passing SafetyNet, the latest version of this module will do the job:

All done! Thanks a lot @1987tlz

I found that the problem occurred when I try to hide the Magisk app, it will installed previous version and cannot change back when restore.

Can others confirm the battery drain with root?

Rooting was the first thing i did with the tablet, i have no reference if it is really draining the battery.

//edit:
removing some bloatware (netflix, chrome, and so one) lead me to a bootloop

Im not finding bootloader unlock and am not sure if i have done it correctly on this samsung device.
This is what i have done,
1.Settings>About Tablet>Software Information
2.Tap Build Number repetitively until Developer Settings Enabled
3.Settings>Developer Options
4. Turn OEM Unlocking on

Is this all there is to it? I feel like im missing something.

*** EDIT
Found that if holding both volume down and volume up while plugging the tablet into my PC i was able to find more options to bootloader unlock as well as warnings. After accepting those it did a factory reset. I hope this is all i needed to do.

Have you tried freezing the bloatware apps with Titanium Backup located in the Play Store?

    Newest update, and I'm just getting a boot screen with a download DID: (16 digit alpha-numeric number) barcode. I tried the unbrick method, but it says "An error has occurred while updating the device software." The device would not load, and it just shows the error screen. After a bit of research and looking, I found out that Frija downloaded the wrong firmware. It downloaded the firmware for SM-G965F no the SM-T773.

    How do I fix this?
    Hi

    what I can suggest :
    + download the correct firmware from Frija, then repeat the various steps,
    + but skip the steps 9 to 13, so do not patch the boot.img with Magisk on the tablet, you will not be abble to do so anyway.
    + add a step 13b where you tar the genuine boot.img thta you've just extracted with lz4
    + then apply step 14 where you push again the genuine boot.img to the table with Odin. that's the most tricky part, if this fails you're stuck.

    if it works you get a new and genuine tablet...
    and you can repeat the full process to root it, but this time with the correct firmware !!!;-)
