Most tasks in LTBox only work while a device is connected. This page shows how to set up the drivers and connect your tablet.

Install the Qualcomm USB drivers (Windows)

If LTBox shows that the required drivers are missing, you will see the "Qualcomm USB drivers are missing" banner on the dashboard.

driver

  1. Click the Download & Install button.
  2. LTBox downloads and installs the drivers from the official qualcomm/qcom-usb-userspace-drivers release.
  3. When the log says the install finished, reboot your PC once. This is recommended.

Connect the device

  1. On the tablet, open Developer options and turn on USB debugging.
  2. Connect the tablet to your PC and start LTBox.
  3. When the Allow USB debugging pop-up appears on the tablet, tap Allow.

adb

If you see an adb server conflict

If the dashboard shows:

An external adb server is holding the USB interface. Kill it to let LTBox connect.

click the Kill Server button next to the message. This stops the other adb server so LTBox can take over the USB connection.

server

Confirm the connection

When the dashboard shows your device information (Model, RAM, Storage, Slot, Anti-Rollback, Firmware), the device is connected.

LTBox dashboard

The status indicator at the bottom-left corner shows the current connection mode (for example ADB, Bootloader, or EDL).

Bootloader mode also shows device information on the dashboard. EDL mode does not show device information. Check the status indicator at the bottom-left instead.
