Tecno and Infinix are both manufactured by Transsion Holdings and share a common USB driver package. Whether you are sideloading an APK, running ADB commands, or performing a flash operation, you need the right driver installed in Windows before any of that is possible. This guide walks you through every step, from downloading the correct package to confirming a live ADB connection.
Transsion Holdings produces Tecno, Infinix, and itel phones from the same manufacturing base. The USB stack is identical across those brands, which means Windows uses a single .inf file to recognize all three. You do not need to find a Tecno-specific package and then a separate Infinix-specific package; one installer covers both. The driver is distributed through the official Tecno support portal at support.tecno-mobile.com under the Tools section, and it is also linked from Infinix's own support site. Either source gives you the same archive.
A separate concern applies to models built on MediaTek chipsets, which covers the majority of budget and mid-range Tecno and Infinix phones. When you need to use SP Flash Tool or similar MTK utilities to recover a bricked device or write a firmware image, you will also need the MediaTek VCOM driver. VCOM and the standard ADB/fastboot driver serve different purposes: VCOM is used during pre-boot flash operations, while the standard driver handles everything that runs through the Android OS or bootloader. Install both if you plan any deep flash work.
Gather the following before you touch Device Manager. You need the Tecno/Infinix USB driver archive (a ZIP file containing an .exe installer or .inf files), Android Platform Tools from developer.android.com (this gives you adb.exe and fastboot.exe), and a USB cable that actually carries data, not just power. Many budget cables fail silently on data lines, so if things go wrong early, try a different cable first.
On Tecno phones running HiOS, open Settings → About Phone and tap Build Number seven times. A toast message confirms that Developer Options are unlocked. Go back to Settings, scroll to the bottom, and open Developer Options. Toggle USB Debugging on. On Infinix phones running XOS the path is the same: Settings → About Phone → Build Number, seven taps, then Developer Options → USB Debugging. The settings app labels may differ by Android version, but the Build Number seven-tap method is consistent across all HiOS and XOS releases since Android 8.
setup.exe installer or a set of .inf files alongside a driver subfolder.setup.exe is present. Follow the prompts and accept the license. When it finishes, skip to step 7. If there is no installer, proceed with the manual method below..inf file and install the driver. If a warning about an unsigned driver appears, click "Install this driver software anyway."adb devices and press Enter. Your phone screen will show an RSA key authorization prompt. Tap Allow. The terminal will list your device serial number with the status device.If your Tecno or Infinix model uses a MediaTek processor (check your phone's specs page on GSMArena if you are unsure), you will need the MTK VCOM driver for flash operations. Power off the phone, hold the Volume Down button, and plug it into the PC. Windows will detect a new device labeled something like "MediaTek USB Port" or "SP Flash Tool USB VCOM." Install the VCOM driver the same way you installed the ADB driver: Device Manager, Update Driver, browse to the extracted VCOM folder. Once installed, SP Flash Tool or MTKClient will be able to communicate with the device in download mode.
