Manually installing MT65xx (MediaTek) USB VCOM drivers on Windows

 Mediatek (MTK) drivers that are unsigned or raw .inf files (instead of .exe installer), needs to be manually installed alongside other drivers in Device Manager .

Requirements

• Download MediaTek USB VCOM drivers from http://rapidtory.com/BCtP
  
•  Download USB Deview ( 32 bit here : 64 bit here )
  
• For windows 7, 8, 8.1 and 10 PC users, you need to disable drivers signature verification for this to work smoothly, see http://rapidtory.com/BCU5 for the procedure

Note

• If you have access to a working phone of the same model then remove the battery from the working phone and connect to PC via USB cord. Mediatek preloader VCOM drivers should be automatically installed so you can skip the rest of this guide. Proceed if automatic installation doesn't work
  
• If SP flash tool or other software still don't detect your phone then also install Mediatek DA VCOM (consider installing more from the list of drivers one at a time if need be  )
  
• If you get the code 10 error after the installation, simply ignore it and proceed with SP flash tool. You're only getting that error because the driver is not digitally signed.
