The problem is that the link for Drivers for Windows 8 isnt the driver
Just look the links:

drivers

For 3 days I've been trying to get my phone to connect but no luck! I've download several of the usb drivers and followed several tutorials but i still can't get this to work!!! The reason I want to do this is because the modem isn't working. It reads the sim cards but I get no single! I think because it was updated ( I didn't do it) and no signal on any sim card! Help on both fronts!! Thanks

Note for the step [4]:

If you can NOT find MT65xx Preloader under Other Devices in the Device Manager go to:

I followed this tutorial and I had the same issue, so I first installed the Windows 7 driver and after that I updated driver to the Windows 8.

I'm using Win8 (x64)

Good luck!

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)

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

ok right click on MT65xx Preloader while its detect in device manager in win8 then choose update driver software and give forcefully update , i mean choose file from folder and give MTK USB Port driver files from driver 64 bit folder of win 8 and its detected after this process end .

Tested by me

Thanks

no go

This is crazy!! I will gladly give a donation to anyone who post a video tutorial on this. I've wasted 7 days on this phone!! HELP PLEASE!!! Is this the only way to install different roms on these phones? If I ever get CWM on here will I be able to install roms like I did when I had the real galaxy phones?

Yes, if u manage to get CWM or TWRP installed then you can flash the SU zip whereby you willl get root.....

BUT, I think I finally got it connected, had to use windows 8 and the vcom drivers and installer in one and it worked. Now when I run the splash tool it now stops and says there isn't enough memory!! I checked my phone and I only have 83.17mb!! I did the factory restore and erased everything I could and this is all I can get!! 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!

Issues with Karbonn K1616(non Android) flash

Hi,
using the instructions mentioned in the post I was able to install MTK drivers in Windows 8. But as some people have complained , the COM port is detected for hardly 2 seconds. I'm trying to flash a non Android Device karbonn K1616. I read most of the places that a flash box is required.
I was trying out few things to get something working with just a micro USB cable. FYI , I have flashed MMX A110 and Karbonn A9+ android devices earlier so ADB are getting detected properly.

I wanted to ask if the flash box is necessary even when I'm able to just detect the COM port in Device Manager, but I haven't been able to download or get the device detected in any of the flash tools so far. I believe the device supports MTK62xx series.

Any advice would be helpful. Thanks All.

HELP?????!!!!!!!!!!!!

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!

[7] PC reboot!

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

[9] Now a MediaTek PreLoader USB VCOM should appear for a brief moment in the Device Manager entry!

[10] At the moment the entry double click and click on "Update driver" under the tab "Driver".

[11] With the wizard in the unzipped MTK 6577 USB VCOM drivers navigate and select the folder for your operating system.

there is no drivers for win 8 please help!!!!!!!!!!!!11

Not able to install Micromax A90s drivers

I have tried this procedure but I am not able to install it. Instead of MediaTek 6577 driver, Mobistel PreLoader USB vcom gets installed. What is the matter? I want to udpate my Micromax A90s to jelly bean.
