i just installed the 64Bit drivers from the 1st post link and now when i connect my phone via USB it shows as A116 connected is this good enough for me to use the SP tool to flash what i want

Note : Yes its working fine for me used SP tool and flashed CWM sucessfully & also flashed melting rock rom
im using win7 64bit OS on my laptop

Samsung Galaxy Grand 16GB with wife
Samsung GalaxyNote 10.1" N8000 32GB SD
Lenovo P780 8GB version 32GB SD

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!
canceled sorry.

Question Issues with Karbonn K1616(non Android) flash

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.

Unhappy HELP?????!!!!!!!!!!!!

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:r olleyes:

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!

Default 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.
