Prerequisites

  • First and foremost, create a complete device backup. This is because we will be wiping the data partition which will format your device.

  • Once that is done, you also need to have the TWRP Recovery installed. You could refer to our guide on How to Install TWRP Recovery on Galaxy Tab A7 10.4 (2020).
  • Also, enable USB Debugging on your device so that it gets recognized by your PC in the ADB Mode. For that, head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging.
  • Next, up, download, and install the Android SDK Platform Tool on your PC. This will provide you with the necessary binary files.

Instructions to Install LineageOS 18.1 on Galaxy Tab A7 10.4 (2020)

  • Transfer the (super.new.ext4.img to the Internal Storage of your device. Ideally push it to an SD card formatted with ExFat or EXT2/3/4 (FAT/FAT16/FAT32/VFAT won’t work due to file-size limitations).

  • Boot your device into TWRP (recovery mode) and format (not wipe) your data partition. Then reboot back into TWRP.

  • TWRP Home

  • Now that your device is booted to TWRP, head over to the Wipe section and tap on Advanced Wipe.

  • Install LineageOS image to “Super” partition. Make sure to select “Install from Image” in order to show .img files in the install selector screen.

  • (Optional) Push NikGapps Omni to your device and install the zip. Make sure you include a “nikgapps.config” file in your “/tmp” folder that is configured to install to “system” rather than “product” or “default”.

  • Reboot to system. You should now be in LOS with Gapps.

  • (Optional, but recommended): Install Magisk via TWRP

  • (Optional, but recommended): Run fix script to fix brightness slider not working and to make Magisk work. If you didn’t install Magisk but only want the brightness fix, just enter “n” when prompted in the script. To run the script:

  • NOTE: Script has a .txt file extension to allow hosting on AFH. Remove that so it’s just .sh to match the instructions below.

  • Download and push to device when booted into TWRP

  • adb push sm-t500_fixes.sh /tmp

  • Enter an adb shell

  • adb shell

  • Change directories and set permissions

  • cd /tmp

  • chmod +x /tmp/sm-t500_fixes.sh

  • Run script

  • /tmp/sm-t500_fixes.sh
