if the ROM is ...XXU4BUD4...then it can not be rooted. 5th character from end is a '4'. That is the bootloader version. Version '4' bootloader prevents rooting. There is currently no solution for this.

What solution? Rooting U4 firmware?
I don't know what they do, but their site and method is well known but their tools and files are encrypted.
Recently they made a site (eftsu.com) so people can find their firmware to obtain root through their methods. Their app is on google play, there's lots of vids in hindi and people showing it works, at least it's not an immediate scam so I'll try it later.

I do not have a spare SM-T295 to test with. I have downloaded the necessary files from EFTSU.com. I will look at them tomorrow.

Hi,
For me it doesn't work. I tried a lot of things, but the Vbmeta in the TWRP 3.40 file, makes an error. So I used the one ATB4 given by Talich52 and it worked, so I reinstalled TWRP successfully. BUT, when I start in recovery, TWRP starts and doesn't recognize my SDcard and when I want to Backup, it starts and abort with the reason that he cannot create a folder because a certificate is missing.
Any idea ?
Thank you.

You need to make sure screen does not go blank when backing up or backup will abort

    I see people still trying to patch files to get root.

    If you flash the TWRP posted by @Talich52, with reboot unchecked you can install Magisk from TWRP.

    Tested on T295XXU3BUC3 ROM (Android 10)

    PREREQUISITES:

    Bootloader unlocked - search forums.xda-developers for instructions how to do this.

    OEM unlock on. In Settings/developer options, OEM Unlock slider should be to the right.

    INSTRUCTIONS:

    1. If prerequisites met: install Android 9 bootloader through ODIN (See attachement: Unzip BL*.zip FIRST)
    If on Android 9, go to step 3.

    2. Reboot to system

    3. Go into download mode.

    4. Open ODIN and in the AP slot put TWRP (see attachment below) (Unzip FIRST)

    5. Uncheck auto reboot

    6. Flash TWRP

    7. Press vol dn + pwr keys.

    8: When screen goes blank, press vol up + pwr keys.

    9. Keep holding down both keys after reboot.

    10. Tablet will reboot again.

    11. When Samsung logo appears stop pressing pwr key.

    12. When bootloader msg appears, release vol up key, quickly press & release pwr key, and quickly press & hold vol up key until in TWRP.

    13. Install Fix_vendor_9.0.zip or Fix_vendor_10.0.zip. (Based on installed OS)
    See attached files.

    14. Clear dalvik/cache if prompted

    15. You will then format (NOT WIPE) data. Answer yes to the format prompt

    16. Clear dalvik and cache.

    17. Reboot back into recovery.

    18. Install magisk - see attached

    19. Reboot into system. System may reboot again - that's okay

    20. Enjoy!!


    WETAmod: (For Android 10 ONLY)

    I have attached a zip file which will add 3Minit Battery, alternate battery options, 3Minit Clock & Network Meter options to the status bar. There are other options inn the WETAmod package. I have tested all the options and they should all work.. Also includes reboot, download, recovery, shutdown tiles for the taskbar dropdown menu (check buttons). On the audio options page, there are instructions for installing Viper4Android - Please READ CAREFULLY.

    The original WETAmod package was developed by @Mentalmuso. He kindly allowed me to post my modified version for the SM-T295 on this forum.

    IMPORTANT:
    The WETAmod*.zip file HAS TO BE INSTALLED in Magisk Manager.

    1. At the bottom of Magisk Manager, you will what looks like a puzzle piece on the right side. Press it. (attachment MM-1.png)
    2. At the top of the Modules page, press 'Install from Storage'
    3. Find & select the WETAmod_T295_1.zip on your tablet's storage.
    4. Installation info will be displayed during install.
    5. Reboot
    6. In the Apps Drawer, launch the WETAmod app. You can browse the options from the menu

    NOTE:
    If the 3MinitBatterySettings is not downloading the battery styles, reinstall the 3MinitBatterySettings.apk. You can extract it from the WETAmod zip file.

    WETAmod_T295_BUC3.zip
    WETAmod_T295_BUC8.zip
    WETAmod_T295_BUD3.zip

    just got a 295, I'm downloading stock T295XXU3BUC3 now. It came with T295XXU3BTI4. I'm not taking any chances, LOL.Thanks for the share gcrutchr.

    Updated the WETAmod zip file to include other battery options, 3Minit Clock, and installing Viper4Android.

    EFTSU file doesn't work too, same "security check fail: boot.img" as magisk patched files did.

    The T295XXU4BUD5, file name "SM-T295_T295XXU4BUD5_10_567dd.9EFT"
    Unless they extracted the correct key signature from the original files, modified TWRP, kernel with it, I do not see how they can get root on U4BUD4/5

    Also, most of the Samsung cpus on this site are Exynos
