On Windows, it will automatically detect all drivers.

Make sure your device is attached to PC, before you install these drivers.

You may need to download drivers for ADB and QDLOADER which are all provided in Lenovo Usb driver.

So Installing these driver will be enough for you and you may need to manually select drivers for rest from lenovo folder

For ADB drivers use LENOVOUSB DRIVER 1.1.16 if your device is not detected by Windows.

For QHUB drivers use these in attachment named QDLOADER HS USB DRIVER.

Simply Install them and you are good to go.

INCASE YOUR DEVICE IS NOT DETECTED

All drivers are contained in these folder C:\Program Files (x86)\LenovoUsbDriver on your PC.

Go to My computer> Properties? Device Manager and see if you have any unknown devices like shown in attachment.

If you have, then I suggest you install manually.

Select unknown device and go in its properties.

Select Browse my computer for drivers

Let me pick from the list of devices

Select have disk

Move to folder C:\Program Files (x86)\LenovoUsbDriver

You will see that there are many folders.

ADB contains all ADB and Bootloader drivers

Use ADB folder if you are installing drivers for adb / fastboot/ bootloader.

Make sure you have usb debugging and device connected when you are installing these drivers. You have to be in normal mode for adb drivers

.

You can check if you have working adb by typing

adb devices

To download fastboot / bootloader drivers, simply first boot your device into fastboot.

Turn off device

hold power and volume down

Now try to install fastboot drivers

Serial Contains EDL drivers (Download mode drivers)

How to enable QHUB drivers if no unknown/ undetected device is seen

Sometimes, your device is not detected in QFIL and you have all drivers installed and there is no unknown device in my computers> device manager.

For this, you will need to attach your device first.

Go to Device Manager by going into my computer properties

Look for ADB Interface drivers in device manager.

Update drivers for ADB interface and replace it with QDLoader HS USB driver.

If it asks for any permission, allow it.

In case your windows do not allow you to install these drivers , you need to turn off Digital Signature Verification in windows

run cmd as run as administrator

Type in these commands

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON

Restart

Then try again to reinstall drivers

To re-enable device verification on Windows

bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING OFF

Good luck
