I’ll just go straight to the point. This simple tutorial will show you steps to properly install Qualcomm QDLoader drivers on Windows, either Windows 8, 8.1 or 10. You may need it in few occasions involving your MIUI device powered with any variant of Qualcomm chipset. As we know it that many of Xiaomi’s most popular phones like Mi5, Mi 5, Redmi Note 3, and so on, are powered with Qualcomm Snapdragon chipset. Any way, let’s just start the guide.

Requirements

• Download Qualcomm QDLoader Drivers package.
• Download ADB USB Drivers or Mi PC Suite.
• Download Minimal Fastboot files.
• Any MIUI device powered with Qualcomm Snapdragon.
• A USB cable.
• A computer running Windows 8, 8.1 or 10.

How to

Step 0 – Extract the Qualcomm QDLoader .zip file using either Winzip or Winrar.

Step 1 – Install either ADB USB Drivers or Mi PC Suite only if you have not done it yet, otherwise you don’t have to. This is necessary to make sure your computer can recognize and communicate with your phone properly.

Step 2 – Extract Minimal Fastboot .zip file and go to the folder of where the extracted files are located (via Windows Explorer).

Step 3 – Enable Developer Options on your phone. Just go toSettings >>About phones >> tap on the MIUI Version 7 times. You can skip this step if you have it enabled previously.

Step 4 – Enable USB Debugging on your phone. Go to Settings >> Additional Settings >>Developer Options >> enable USB Debugging.

Step 5 – Now reboot your phone into Fastboot mode. In most cases, you can do it by pressing Volume Down (-) button and Power button simultaneously until Fastboot Bunny logo appeared.

Step 6 – Now connect your phone into your computer.

Step 7 – In Windows Explorer opening Minimal Fastboot Files folder, hold down / press the Shift button on your keyboard and right-click anywhere in the folder, and then choose “Open Command Window from Here” option.

Step 8 – Now type following command :

Your phone shall now reboot into EDL mode

Step 9 – Open up Device Manager from control panel and you will notice a new device is detected but its driver is not installed properly.

Usually it is displayed as “QHSUSB_BULK” under Other Devices.

Step 10 – Right-click on QHSUSB_BULK and choose “Update Driver Software“.

Step 11 – A dialog window shall appear. Choose “Browse my computer for driver software“.

Step 12 – Now click on the Browse button and locate the extracted Qualcomm QDLoader drivers.

Step 13 – The installation process shall take place immediately and a system notification will appear. Just choose “Install this driver software anyway“.

Step 14 – Once done, you will see something like this.

Step 15 – Click the Close button and check back at Device Manager window. You will now see “Qualcomm HS-USB QDLoader 9008 (COM10)” under Ports (COM & LPT) section.

Done! Congratulation, you have now installed Qualcomm HS-USB QDLoader successfully on your computer.

FTDI Driver Installation

Development boards such as the SparkFun RedBoard for Arduino and the Arduino Uno require special drivers or code that tells the computer how to interact with them. This guide is here to help you get this driver software installed as quickly as possible so you can get back to building circuits and learning about electronics!

These instructions apply to both the Arduino Uno, the Arduino Uno SMD, and the SparkFun RedBoard for Arduino.

Scroll down to the corresponding section for whichever operating system (OS) you are using.

Windows

Plug the board into your computer. Windows will likely complain about the device not having the correct driver. It may attempt to find it. If you have never plugged in a similar device to your computer, it probably won't find a driver to use. Luckily, when you downloaded the Arduino IDE, it also came with all the necessary drivers.

To install the correct driver, open the Device Manger. This can be found be searching for 'device manager' in the start menu. Once Device Manager is open, you should see a device with a tiny yellow triangle and exclamation mark next to it.

If you plugged in a SparkFun RedBoard, it will look like the image on the left. Plugging in an Arduino Uno will result in the image on the right.

Right-click on the unknown device, and select Properties.

In the properties window, select Driver Details.

Select the Browse my computer for driver software option.

Navigate to the destination where you installed the Arduino IDE. On Windows, this will most likely be in your Program Files folder. Navigate to the drivers folder found inside the main Arduino folder. You can select the entire folder or the specific driver. needed Your path should look something like this but may vary:

Once the driver installation is complete, you should see the device reappear in the Device Manager window as a usable COM port. The number will vary depending on how many devices you have plugged into your computer. The RedBoard will appear as a USB Serial Port, as shown in the left image. The Uno will appear as an Arduino Uno, as shown in the right image.

In the Arduino IDE, you should see that same serial port available under Tools -> Port.

If you are experiencing problems, please see our in-depth instructions.

MacOS

Plug the board into your computer. Once plugged in, the operating system should recognize it as the appropriate device. In the Arduino IDE, click Tool -> Ports to ensure the device has been recognized. The SparkFun RedBoard will appear a cu.usbserial-XXXXXX device.

The Arduino Uno will appear as a cu.usbmodemXXXXXX device.

If you do not see an available serial port in the Arduino IDE after plugging in your board and waiting a moment, then you may need to install the drivers by hand. To do so, please see our in-depth instructions.

Linux

Plug the board into your computer. Once plugged in, the operating system should recognize it as the appropriate device. In the Arduino IDE, click Tool -> Ports to ensure the device has been recognized. The SparkFun RedBoard will appear a ttyUSBXX device.

The Arduino Uno will appear as a ttyACMXX device.
