Most importantly the Preloader USB VCOM driver that is essential for getting
the SmartPhone Flash Tool (SPFT) to work.

Contents:

Android\android_winusb.inf
Installs ADB (Android Debug Bridge, “USB-Debugging”) driver for
MediaTek’s vendor ID (VID_0E8D).
Optional. Your Android device might use a different vender ID anyway,
so you should first try the vendor’s ADB driver, if available.

CDC\cdc-acm.inf
Installs VCOM (virtual serial port) driver.
Required for the SPFT!

tetherxp.inf
“RNDIS-over-USB host driver for Intenet Sharing”.
You probably don’t need this.

wpdmtp.inf
Media Transfer Protocol (MTP) driver for MediaTek’s vendor ID.
You probably don’t need this on modern operating systems.

To install any of these INF files, first extract this ZIP archive.

Then, for Windows 8 and 10:
Simply right-click any extracted INF file,
and select “Install” in the appearing context menu.

For Windows 7:

• Open the Windows Device Manager
• In the “Action” menu, click “Add legacy hardware”
• Click Next
• Select “Install the hardware that I manually select from a list (Advanced)”
• Click Next
• In the list, select “Ports (COM & LPT)”
• Click Next
• Click “Have Disk…”
• Browse for the INF file, e.g. cdc-acm.inf
• Select the driver you want to install, e.g. “MediaTek PreLoader USB VCOM (Android)”
• If a new device appears in the Device Manager with a yellow warning triangle
  and error code 10, just select it and delete it (delete key). But do NOT delete
  the driver software.

2. Install MediaTek SP Flash Tool (SPFT)
3. Extract firmware archive
4. Start SPFT
5. Make sure “Download Only” mode is selected
6. Load scatter file from extracted firmware
7. SPFT should auto-load firmware and verify checksum
8. Optional: select DA_SWSEC.bin as Download Agent
9. Optional: remove checkbox from partitions you do not want to flash
10. Click the Download button in SPFT
11. Turn off tablet completely
12. Hold volume-UP key on tablet while connecting it to PC via USB
13. After a few seconds, SPFT should find tablet and start
14. Release volume-UP key and wait for flashing to finish

Note: when you load a scatter file, there MUST be a valid preloader
in the same directory as the scatter file, or else an error will
occur when you start a download/flash. You can clear the checkbox of
the preloader, so that it won’t be flashed, but its “Location” field
must be filled.
