  • How to Root Lenovo TB373FU (Step-by-Step Guide)

    ⚠️ Disclaimer: Rooting your device will void your warranty and carries the risk of bricking your tablet if not done correctly. Proceed only if you’re comfortable with the risks. Always back up your important data first.

    1. Enable Developer Options

    1. Go to Settings → About Tablet → Tap “Build Number” 7 times to enable Developer Mode.
    2. In Developer Options, enable:
      • OEM Unlocking
      • USB Debugging

    2. Prepare Stock Firmware

    • Download the stock firmware for your Lenovo TB373FU.
    • Keep it safe on your PC in case you need to restore the device.

    👉 This is important because if anything goes wrong, you’ll need the stock firmware to unbrick your tablet.

    3. Extract Boot Files

    • From the firmware package, locate boot.img and init_boot.img.
    • Copy both files to your tablet’s internal storage or SD card.

    4. Patch with Magisk

    1. Download and install the Magisk app on your tablet.
    2. Open Magisk and patch the boot.img and init_boot.img files.
    3. Once patched, move the patched files back to your PC.
      • For organization, keep two folders:
        • Stock Firmware (non-root)
        • Patched Firmware (root)
      • This way you avoid mixing files and prevent conflicts.

    5. Unlock Bootloader

    1. Download and install ADB & Fastboot (platform-tools) on your PC.
    2. Connect your tablet via USB, then run: adb reboot bootloader This will reboot your tablet into Fastboot mode.
    3. Next, run the command: fastboot flashing unlock_critical
    4. On your tablet, follow the on-screen instructions and press Volume Up (or Down, depending on the prompt) to confirm.
    5. Once complete, your tablet is now officially bootloader unlocked.

    6. Enter Brom Mode

    1. Power off your tablet.
    2. Hold Volume Up + Volume Down together while connecting the tablet to your PC via USB.
    3. The device will now boot into BROM mode.

    7. Flash with SP Flash Tool

    1. Open SPFlashToolV6.exe on your PC.
    2. In SP Flash Tool, load:
      • Download XML → Firmware → image → download_agent → flash.xml
      • Auth File → Firmware → image → da.auth
    3. Once firmware files are loaded, replace:
      • boot_a with patched boot.img
      • boot_b with patched boot.img
      • init_boot_a with patched init_boot.img
      • init_boot_b with patched init_boot.img
    4. Start the flashing process.
    5. After it completes, the tablet will reboot automatically with root access enabled.

    8. Verify Root

    • Once the tablet restarts, open the Magisk app to confirm root access.
    • Optionally, use an app like Root Checker to verify everything is working.
