MT6575 Driver Installtion Step by Step jpalpano

I have experienced so much frustration installing the drivers for the first time, in order to use it with SP-Flash Tool and SP-MDT Tool.

It took a lot of research, trial and error, and hair-pulling activities before I was able to finally do it.

So to help our newbies out there, I hope this guide may help you.

This is for you if your problem is:

The Flasht Tool or SP-MDT Tool cannot detect your phone.

When you plug your phone, you hear it connecting, and disconnecting immediately in Windows.

Your phone goes into connecting and disconnecting state.

Your phone can be flashed via the SP-Flash Tool, but not through the SP-MDT Tool

The Basics:

There are actually 2 different types of drivers for this phone:

1. The USB driver

- You need to have this installed in order for you to use it via ADB Devices, USB Debugging mode, TPSparky Root tool, etc.

- This driver is needed for activities where the phone remains turned on.

- The component of this driver will appear as MT65xx ADB Interface device

2. The Preloader driver

- You need to have this installed in order for you to use it with the Flashing Tool and SP-MDT Tool

- This driver is needed for activities where the phone is turned off.

- There are two components of this driver: The Meditatek USB VCOM driver and the Mediatek USB DA VCOM driver

The Tools:

There are two types of tools you can use for updating this phone:

1. The SP-Flash Tool

- This is easier to use as long as you have correctly installed the device drivers

- This is recommended for flashing only a few parts of the ROM, like for example, changing only the recovery, uboot, and boot images.

2. The SP-MDT Tool

- This is an advanced tool which allows you to set the display drivers

- The installation of the driver is a little more complex for this tool in order for your phone to be detected

- If you are able to successfully flash using the SP-Flashtool, but then your display is black, wrong color, twisted, etc, this tool is what you need.

There are a lot of people who are able to successfully install drivers and flash using the SP-Flashtool,

but to no success when using the SP-MDT tool.

In my experience, once I got to make the SP-MDT tool work, I had no use for SP-Flashtool anymore.

The Procedure

First of all, if you have installed the drivers already, and think it doesn't work, I recommend to clear out all

Android drivers you have installed using the USB Deview tool.

Delete all those drivers there that starts with MT.

Also delete any other drivers you might have installed for your old or other Android Devices.

ADB Interface Device

Turn your phone on and switch on the USB Debuggin mode under Settings>Developer Options.

Plug your phone to your computer

On the Hardware Update Wizard, select Install from a specific list or specific location (Advanced) option. Click Next.

Choose Don't search. I will choose the driver to install option. Click Next.

On the Hardware Type screen, select Show All Devices then click Next. (Some of you may not see this screen)

Click the Have Disk... button.

On the pop-up, click the Browse button and look for the android_winusb.inf driver in your hard drive (link below).

Open it then Click OK.

Click the Next button and wait for Windows to install the driver.

You may be notified by windows about failure for driver verification, just select Continue Anyway

Once done, it should successfully install the driver.

Check if you phone can be detected now via the ADB Devices.

You can now use the TPSparky root tool to root your phone and install SuperUser.

USB VCOM and USB DA VCOM drivers

Launch your Device Manager and Expand the Ports (COM & LPT) section.

Resize the screen ofyour Device Manager in a way that you see the Ports section without having to scroll down the window.

Make this window always visible. Do not minimize it.

PART 1

Turn off your phone and remove the battery.

Plug your phone into your PC and wait for it to be detected.

Windows should automatically bring up the Hardware Update Wizard.

If it did not, that means you have not totally deleted the old drivers using the USB Deview tool.

On the Hardware Update Wizard, select Install from a specific list or specific location (Advanced) option. Click Next.

Choose Don't search. I will choose the driver to install option. Click Next.

On the Hardware Type screen, select Show All Devices then click Next. (Some may not see this screen)

Click the Have Disk... button.

On the pop-up, click the Browse button and look for the driver in your hard drive. Open it then Click OK.

Click the Next button and wait for Windows to install the driver.

You may be notified by windows about failure for driver verification, just select Continue Anyway

Once done, it should successfully install the driver.

The device manager should refresh and you should see the driver in the Ports section.

But then you will notice it will disappear, and you will hear the USB disconnected sound right away. This is alright.

PART 2

Disconnect your phone from USB

Insert the battery back

Plug your phone into the computer again.

You should be prompted for the drivers again.

Follow the same steps above and use the same driver file.

Once installed, the phone will disappear from Device Manager again. That is alright. Do not worry.

After Parts 1 and 2 above, you should have been able to install both the USB VCOM and USB DA VCOM drivers.

You should now be able to flash using both of the flash tools.

SP-Flashtool can detect it but not SP-MDT tool

In order for SP-MDT tool to work, your driver should be installed between COM1 and COM16.

If not, then SP-MDT cannot flash your phone.

To solve it, you must force assign the COM port for your phone.

These steps are a little tricky so you must have quick hands.

Turn off your phone and disconnect from your computer

Remove battery for a few seconds, then put it back. Don't turn on.

On your device manager, focus your eyes on the Ports section

Connect your phone to the USB.

The device manager shall refresh and you should see your phone under the Ports section with the COM# in parenthesis (ex: COM8).

If the COM# of your phone is COM17 and up, then we have to change it.

Your eyes should be quick because this will disappear in a few seconds.

Disconnect again the phone from USB.

Remove battery again, then put it back.

Now, position your mouse over the part where you saw your phone in the Ports section.

Connect your phone to the USB.

When the Device Manager refreshes and shows your devices, immediately double click it before it disappears again.

The properties of the device should now pop-up.

Click the Port Setttings tab and click the Advanced.. button.

On the bottom of the new window is a COM Port Number drop-down menu, showing the current port # assigned to your phone.

Click the drop-down and select any available COM ports between COM1 and COM16. (I used COM8 with mine).

Click OK, then OK again.

Disconnect and Reconnect your phone again and make sure that device manager already show it under the COM# you assigned.

Your device should now be detected by the SP-MDT Tool.
