DeepSmartTool (DST) Flashing Tool Free Download 2026

DeepSmartTool, often called DST, is a special software used to fix dead or bricked Android phones that use Qualcomm chips. It can flash firmware, read and write partitions, and help bring back phones that do not start normally.

Many phone repair tools work only for common errors. But DST goes deeper. It works with the EDL mode (Emergency Download Mode) used by Qualcomm phones to recover hard-bricked devices. This mode is built into the phone hardware and helps in deep recovery.

In this article, we will explain what DST is, which phones it supports, and how to use it in simple words.

What Is DeepSmartTool (DST)?

DeepSmartTool (DST) is a Windows program made for Qualcomm Android phones. It is mainly used to flash firmware in EDL mode and unbrick devices like OnePlus, Oppo, Realme, Xiaomi, and some other brands.

The tool has many useful options:

Detect EDL mode automatically
Read and write partitions
Backup partitions before changes
Erase unwanted partitions
Flash firmware files

It also helps install drivers and manage phone partitions easily.

What Is EDL Mode?

EDL mode means Emergency Download Mode. This is a special Qualcomm mode that runs when a phone is deeply stuck or bricked. In this mode, the phone shows up on the computer as Qualcomm HS-USB QDLoader 9008. This allows tools like DST to communicate with the phone below the normal Android system.

To use DST, your phone must be in EDL mode.

How to Use DeepSmartTool — Step by Step

Step 1 — Get Firmware Files

First, download the correct EDL firmware for your phone. The firmware usually comes with rawprogram0.xml and other XML files.

Step 2 — Run DeepSmartTool

Open the tool on your Windows computer by double-clicking its EXE file.

Step 3 — Find Flash Option

Go to the EDL flash section (often inside the Qualcomm module). It may be the second tab.

Step 4 — Load Files

Choose your chipset in the first dropdown. Then load rawprogram0.xml by double-clicking the second dropdown. This loads all partitions.

Step 5 — Adjust Partitions

Before flashing, you can uncheck partitions you do not want to overwrite, such as:

persist (Fingerprint)
fcs, fsg, modemst1, modemst2 (IMEI)
ocdt (Network)

Step 6 — Enter EDL Mode

Turn off your phone. Then press and hold both Volume Up and Down buttons together. While holding, connect the USB cable to the phone. The tool should detect the phone in EDL mode.
