What is QFIL and what does it do?
QFIL stands for Qualcomm Flash Image Loader, a software tool developed by Qualcomm Technologies Inc. It is part of the Qualcomm Product Support Tool (QPST), a suite of utilities that help users manage their Qualcomm devices. QFIL is designed to flash firmware or stock ROM on Qualcomm devices in Emergency Download (EDL) Mode. EDL Mode is a special mode that allows the device to communicate with the PC via USB and receive commands for flashing. Firmware or stock ROM is the software that runs on your device and controls its functions. Flashing firmware can help you update your device, fix software issues, or restore it from a brick.
Why do you need QFIL and when to use it?
You might need QFIL if you want to flash firmware on your Qualcomm device for various reasons. For example, you might want to update your device to the latest version of Android or install a custom ROM that offers more features and customization options. You might also want to fix some software problems that affect your device's performance or functionality. Or you might want to unbrick your device if it is stuck in a boot loop, won't turn on, or shows other signs of corruption. In any of these cases, QFIL can help you flash the firmware file that matches your device model and chipset.

After installing QPST, you will find QFIL in the bin folder of the installation directory. You can also launch QFIL from the Start menu or create a shortcut on your desktop.
How to use QFIL
To use QFIL, you need to prepare your device for flashing first. You need to boot your device into EDL Mode and connect it to your PC via USB cable. Different devices have different methods of entering EDL Mode. Some devices can enter EDL Mode by holding both volume buttons while powered off. Some devices require fastboot commands or test points. You can find more information about how to enter EDL Mode for your device at [15]( Once your device is in EDL Mode, you should see Qualcomm HS-USB QDLoader 9008 port in the Device Manager of your PC. If you don't see this port, you might need to install the Qualcomm USB drivers on your PC.

After loading the firmware file, you can select the flash options that suit your needs. You can choose between two modes: Flat Build or Meta Build. Flat Build is the default mode and it flashes all the partitions of the firmware file. Meta Build is an advanced mode and it allows you to flash specific partitions of the firmware file. You can also choose between two methods: UFS or eMMC. UFS is a newer and faster storage technology than eMMC. You should choose the method that matches your device's storage type. You can check your device's storage type by using a tool like [12]( To select the flash options, follow these steps: - In QFIL, click on the Select Build Type button and choose Flat Build or Meta Build from the drop-down menu. - In QFIL, click on the Select Programmer button and choose UFS or eMMC from the drop-down menu.

You will see messages like Downloading Programmer, Sending Configuration, Flashing, etc. When the flashing process is complete, you will see a message like Download Succeed or Download Success in green color in the log window. You can also hear a sound notification from your PC. After flashing your device with QFIL, you can disconnect it from your PC and reboot it.
