Since here every day again and again problems with the USB VCOM driver installation for MTK6577 appear Phones, here is a short guide to the installation, and a final, successful test with SPFlashtool!


Installation of the USB VCOM driver:

[1] With USBDeview, clean up your PC from all possible old MTK VCOM entries, then reboot your PC.

[2] Smartphone is switched off, and still dont connect via USB to the PC.

[3] Open Device Manager and leave it open!

[4] Your switched off Smartphone with inserted rechargeable battery via USB connect now on the PC, you should now see a MT65xx preloader in the Device Manager.
(With some MTK6577 Smartphones should be installed without battery. Please before hand inform.)

[5] now launch the Installdriver.exe from the unzipped MT6577 USB VCOM drivers folder. Confirm the installation of unsigned drivers

[6] now! (W7 x 64 this confirmation comes later in the manual installation!) After the installation is complete, you have no entry in the Device Manager, it is correctly!

[8] Open Device Manager and open the switched-off Smartphone via USB to the PC release, now connect (same USB port!)

After installing all drivers and connecting the phone to pc without battery, the device manager shows it as mt65xx preloader.. but in few seconds it goes off . It comes as an unknown device..

Sent from my Micromax A116 using xda premium

Don't worry about that "unknown device"

You can connect your phone and continue to Flash.

If driver is not there for your phone then SP Flash Tool will keep on searching for your phone.

If driver is installed then SP Flash Tool will continue and start Flashing your phone.

Worked on Windows 8... Please follow the correct procedure. Just i flashed TWRP and replaced CMW (for testing only) and work fine.
If needed, i can post again the full procedure to flash CMW / TWRP / LEWA recovery.

Please do..:good:
Hello All,
I tried both on window 7 & 8; 64 bit and procedure as mentioned by the OP is perfect; however i am posting it again here
1) Download the flash tools from anywhere preferably most updated one: SP_Flash_Tool_v3.1224.01
2) Download the recovery which ever you like TWRP / CMW (I tried both of them now and they are working for me on MMX A110)
3) In your desktop / laptop please ensure you allow installation of unsigned drivers (youtube will help for this)
4) Download and install MTK6577 Drivers for your device (this will only work after you clear step 3)
5) If still not working, download USBDEVIEW (usb driver remover) and run it as "Administrator" uninstall all the USB drivers relevant to your device and repeat above steps
6) Now connect your phone, with portable media option selected in USB or the default mode. Let it install and finish
7) Once done switch-off your phone while it is connected through USB (Again this will install a driver which will look like MTK65xx something...
8) Remove the battery of phone let your PC install the driver again (battery not plugged in, only phone connected with USB). You will see for a shot time that charging icon will appear on phone and disappear; this will install something in the background again on your PC
10) To confirm this, put your battrey again back in your phone with USB (still) connected to PC
11) go to system manager of your PC and look for MTK 6577 something ... something... driver
12) Now disconnect your phone and switch it on
13) Start the flash tool
14) Select the recovery option only in tool (TWRP / CMW / LEWA Whichever you like)
15) Click download
16) Connect your phone (which i assume is switched on), once you connect switch it off (no need to remove battery or anything)
18) Look at the status bar of your flash tool (nothing to worry, no need to do anything)
19) RED Bar -> Yellow Bar -> Green Ring
20) Disconnect
21) Reboot in recovery (TWRP / CMW / LEWA) is flashed...

I've followed ALL the instructions word for word now and still can't get it to install the MT6577 drivers correctly. I've tried the OP's method as well as apoorv.mehrotra's method. Have rebooted my PC now 28 times! Still can't get it to work. I have exactly the same problem as everyone else - the phone appears in device manager for 3 seconds then disconnects suddenly. Even the legacy installation method does not work. I've tried on a Windows 7 64-bit machine as well as a Windows XP 32-bit machine - exactly the same outcome each time.

Help!

    I'm also having major troubles.
    Tried all the various instructions on win 8 x64 and win 7 x64 and the same thing keeps happening... the VCOM port will show for a couple of seconds, then disappear. When using the flash tool, it'll start, then just stop when the device disappears.

    I suspect it's the phone (B92M) doing this, don't know if I need to put it in some kind of mode (recovery doesn't help)

    I've followed ALL the instructions word for word now and still can't get it to install the MT6577 drivers correctly. I've tried the OP's method as well as apoorv.mehrotra's method. Have rebooted my PC now 28 times! Still can't get it to work. I have exactly the same problem as everyone else - the phone appears in device manager for 3 seconds then disconnects suddenly. Even the legacy installation method does not work. I've tried on a Windows 7 64-bit machine as well as a Windows XP 32-bit machine - exactly the same outcome each time.

    Help!

    The fact that the "preloader COM port" appears and then disappears 3 sec later IS THE CORRECT BEHAVIOR!! I also had a hard time with this driver because I thought it meant there was a problem. That's why when you flash with Flash_tool.exe, you FIRST click on "download" THEN connect the (off) phone. Flash_tool will connect to it in the brief moment it is seen by the device manager and KEEP IT CONNECTED while it flashes!
    IMHO, this information should be included in red in the 1st post because it seems to throw off a lot of people!

    Mediatek WHQL signed drivers. No need to Disable Driver Signature Verification on 64-Bit Windows.
    http://www.mediafire.com/download/64fabkzkk9qfhkm/MTK_USB_COM_Driver_SDK_v1.12.50.0_WHQL.rar

    MediaTeks all serial port versions uses same driver, So if even your USB\VID_XXXX&PID_XXXX is not listed in this driver, just select one of listed and signed devices from list. They will still work.
