Anyone know if there's a way to disable OEM lock if I can't get into the tablet. Bought a used one on eBay and it was reset before it was shipped to me so it's basically a paperweight without logging into a Knox manage account. Just wanted a sturdy tablet to use. Looks like I wasted money.

If I installed 9.0 but it only works halfway, it does not make backup copies or restores copies, nor does it leave me when you are going to close it the option to finish installing the twrp, it closes and some more error, but install the zip and something else if does a greeting

    This is a TWRP 3.2.3 build based on Android 7.1.2 source kernel for the Galaxy Tab Active 2 (codename: gtactive2lte) - Exynos. The "tar" file should be installed using Odin (tested on Odin 3.12.3).

    Special Notes:
    1. DON'T FORGET TO ENABLE "OEM UNLOCK" (located in Developers options, if its not there, you may have to wait for a few days to access that option, some users claim that its within 10 days before this option appears).
    2. KNOX will be tripped once you flashed custom binaries to your phone.
    3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries.
    (You can flash custom ROMs if you want to keep the OS up-to-date.)
    4. It is HIGHLY UNRECOMMENDED to purchase any access to any kind of private forums, ROMs or Kernels.(DO NOT GET FOOLED.)

    Installation process:
    1. Flash Stock ROM.
    2. Flash recovery using Odin (AP = recovery.tar).
    3. Load recovery immediately after flashing.
    4. Format data (Will erase /data partition).
    5. Reboot to recovery.
    6. ADB push SuperSU to internal storage / insert SD-Card with SuperSU.zip.
    7. Flash SuperSU using TWRP install option.
    8. Reboot to system (May bootloop several times. Wait untill system loads).

    1. ADB sometimes doesn't work in MTP mode. Need to manually change to PTP in order to get adb usage.
    2. Bad label in ADB shell + bad characters appearing while writing through AD. Works well out of recovery and on recovery's terminal.

    Many thanks to TWRP's developers for the support on building this recovery.
    Special thanks to CaptainThrowback, Bigbiff and Dees_Troy on TWRP-freenode and Ashyx on xda-developers.

    Please post any bugs you encounter. I will try to fix any issues that come up.
    This will be great, let me know if I can help, perhaps document.

    Ok, so this is a first try, so I believe it's not going to work, but who knows? we may get lucky.
    Recovery for SM-T397 - Android 7.1.2

    If it doesn't get installed or leads to a bootloop, I'm gonna need you to pull the boot.img from your device, or send me a link of the stock ROM if it's available.
    Please follow the intsallation process described on the README file on the github repository
