Should You Still Use ADB Setup 1.4.3 in 2026?

It depends on what you want to do. The installer is fast and convenient, but the ADB and Fastboot binaries inside are from 2016.

Task	ADB Setup 1.4.3	Platform Tools 37 (Google)
Install the USB driver quickly	✅ Yes, one click	Separate Google USB driver
Basic ADB: adb devices, install APKs, debloat	✅ Usually works	✅ Works
Unlock the bootloader with Mi Unlock	✅ Works (Mi Unlock has its own Fastboot)	✅ Works
Flash a HyperOS Fastboot ROM, super images, fastbootd	⚠️ Often fails with old Fastboot	✅ Recommended
Wireless debugging (adb pair, Android 11+)	❌ Not supported	✅ Supported

Our recommendation: use ADB Setup 1.4.3 to install the driver, then replace the old ADB files with the current Platform Tools r37 from Google. This takes two minutes and avoids most “it doesn’t work with my new phone” problems. The steps are below.

How to Install ADB Setup 1.4.3 on Windows 11 / 10

1. Download adb-setup-1.4.3.zip and extract it.
2. Right-click adb-setup-1.4.3.exe and choose Run as administrator.
3. A black window asks three questions. Type Y and press Enter for each: Install ADB and Fastboot? → Y, Install ADB system-wide? → Y (so it works from any folder), Install device drivers? → Y.
4. A driver installation window opens. Click Next, then Finish. If Windows asks whether to install the Google driver, click Install.
5. Open a new Command Prompt and type adb version. If you see a version number, ADB is installed. The files are in C:\adb.

Upgrade to the Current ADB and Fastboot (Recommended)

1. Download Platform Tools for Windows and extract it.
2. Close all Command Prompt windows and run taskkill /f /im adb.exe to stop the old ADB server.
3. Copy all files from the extracted platform-tools folder into C:\adb and confirm Replace.
4. Run adb version again. It should now report version 37.0.1. Your PATH setting and drivers stay the same.

Common Errors and Fixes

“adb server version (32) doesn’t match this client (41); killing…”

You have two ADB versions on your PC: the old one from ADB Setup 1.4.3 and a newer one (from Platform Tools, Mi Flash or a phone-manager app). Use one copy only. The easiest fix is to replace the files in C:\adb with the current Platform Tools as shown above.

“‘adb’ is not recognized as an internal or external command”

You answered N to “system-wide” or opened Command Prompt before the installation finished. Open a new window, or run the installer again and answer Y to all three questions.

Fastboot errors when flashing a new ROM

Messages like “Invalid sparse file format”, “unknown option” or a flash that stops on super usually mean the 2016 Fastboot is too old for the ROM. Upgrade to Platform Tools and run the flash again. For Xiaomi Fastboot ROMs, Mi Flash Tool brings its own Fastboot.

The phone isn’t detected in Fastboot mode

Open Device Manager. If you see Android with a yellow mark, right-click → Update driver → Browse my computer → Let me pick → Android Bootloader Interface. Use a USB 2.0 port and the original cable. If the phone shows up as QHSUSB_BULK or 9008, it is in EDL mode and needs the Qualcomm QDLoader driver.

FAQ

Is ADB Setup 1.4.3 safe?

The SHA-256 hash of our file is listed above. Compare it to check that your download is complete and unchanged. Because it installs system drivers and changes the PATH, some antivirus programs and sandboxes flag it as “potentially unwanted”. If you want to be sure, upload it to VirusTotal before running it, or skip it and use Google’s Platform Tools with the Google USB driver instead.

What is the difference between 1.4.3 and 1.4.4–1.4.6?

Versions 1.4.4 to 1.4.6 are repacks made by androidmtk.com (2019–2020), not by the original author. They still contain a much older ADB and Fastboot than Google’s Platform Tools. If you need a newer ADB, use Platform Tools instead.

Does it work on Mac or Linux?

No, ADB Setup is Windows-only. On macOS and Linux, use Google’s Platform Tools (or brew install --cask android-platform-tools on a Mac).

Do I need it for Xiaomi phones?

Only for the driver and basic ADB. For bootloader unlocking, follow our HyperOS unlock guide. For official ROMs, see the Xiaomi firmware download pages.
