LTBox Wiki

LTBox is a tool for flashing and modifying firmware on certain Lenovo tablets. It can switch firmware between the PRC (China) and ROW (Global) regions, root and unroot the device, bypass anti-rollback, and read or write partitions over EDL (9008) mode.

⚠️ Educational purposes only. Modifying firmware can brick your device, cause data loss, or void your warranty. You use LTBox at your own risk.

Quick Start

🪟 Windows — x86_64 / arm64

1. Download the latest release and extract the zip (no spaces or special characters in the path).
2. Double-click ltbox.exe.
3. Pick a task from the sidebar and follow the wizard.

Qualcomm USB drivers: the dashboard shows an "Install drivers" banner when the Qualcomm USB drivers are missing. Clicking it downloads and installs the latest qcom-usb-kernel-drivers release from GitHub via pnputil. Run LTBox as Administrator the first time so pnputil can land the .inf files.

🐧 Linux — x86_64 / aarch64

1. Install the runtime dependencies (Debian/Ubuntu shown — adapt for your distro):

   sudo apt install \
     libusb-1.0-0 libudev1 \
     libxkbcommon0 libxkbcommon-x11-0 libwayland-client0 \
     libxcb1 libxcb-render0 libxcb-shape0 libxcb-xfixes0 \
     libfontconfig1 \
     xdg-utils

2. Download the latest release Linux tarball and extract it (tar -xzf LTBox-linux_*.tar.gz). The executable bit on ltbox is preserved.
3. Install the udev rules so the desktop session can open the Qualcomm 9008 / Lenovo USB devices without root:

   sudo ./ltbox --install-udev

4. Replug any connected device.
5. (Optional) Add an app-menu entry and icon (per-user, no root):

   ./ltbox --install-desktop

   This drops a .desktop file under ~/.local/share/applications/ and the SVG icon under ~/.local/share/icons/hicolor/scalable/apps/. GNOME / KDE pick it up within a few seconds. Re-run after moving the binary.
6. Run ./ltbox.
