[TUT] Instructions MTK6577 USB VCOM Driver Installation

[culae]

error message with the SP flashtool

I tried to follow the guide step by step. I had some problems. as at step 9 I didn't have a "Media Tek Preloader..." but a something generic (like "unknown device..."). going on I didn't get a succesful instalation of the driver.
but continuing with the SP flashtool succeded nothing and after unpluging and repluging the Goophone i5S from the computer (still in off-mode) I get this message from flashtool (see attacment):

what the problem could be, guys?

 

[zEr!]

Let me get this straight

and you cited ALL THE GUIDE just to say you don't find the driver?!!? could you, please, delete the unnecesary and long texts with no relevance to your question?

Hello, First, the windows8 drivers work fine, you just need to turn off the driver signing check, or windows wont load. i just did it and worked fine. To turn off the driver signing, you need to press shift + "restart" on your windows and select the following:

• Troubleshoot
• Advanced
• Startup Settings
• After restart, select option 7

After that, try to install the driver on the Unknown device or the yellow marked PreLoader.
I hope it helps.

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.

help guys this is really annoying :crying:
When i want to install drivers for usb while my phone is turned off and unplugged the battery, there is messing with usb port. It goes all the time on and off. The port goes nuts and sound all the time with plugged on/off
Android ADB interface is installing successfully but for rooting, i guess i must fill this step
" 4. Install your usb driver.disconnect your phone after driver installation,remove the battery and put it back in/don’t turn it on.
"
Please help

hello,

I have a Wiko Darkfull but not of this phone to remove the battery ... know any way to install the drivers in order to use SP Flash Tool?

Hy, I installed the VCOM drivers on Win 8 , in USBDeview I see the drivers but SP Flash Tool still gives me the error.

Maybe I need to try on Win XP? Maybe have better luck?

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

Download MT6577 USB VCOM Driver (W7/Vista/XP) -> http://www.mediafire.com/?cypm22rgs2k83ji
300kb?


Download MT6577 USB VCOM Driver (W8) -> http://www.mediafire.com/?7yee2of64nhl947
8 mg???

can the win8 version work with MT6589?

[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.)...

And what if MT65xx Preloader didn't appear at all ? What's wrong ? I can't go with your guide because when I connect my phone (switched off) nothing appears. Even without a battery the same thing happens.

it's tough but i think you can get through this...do you have root or not yet ? if not than go to my topic about H7100 (http://forum.xda-developers.com/general/general/h7100-alternate-rooting-cwm-adjust-t2913381) and follow my steps of how to root your MTK phone (that topic is about my H7100 and the recovery is ONLY for that phone !!!)....if you already have your phone rooted than just install Flashify and extract the recovery.img from that update.zip you've got and flash it....good luck

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.

if this is shown, after updating driver, what should i do?
