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.

Check this file and see images for install driver in W7. Remember, install this as administrator. Installation also depends on the version of w7, it is x32 or x64.

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.

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...

Plz can anyone post video tutorial of installing this rom do favour
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!
It worked on my windows 8 x64. To install these drivers you need to bypass driver signature enforcement. Follow the instructions at http://www.craftedge.com/tutorials/driver_install_windows8/driver_install_win8.html
I searched the forums but couldn't find any answers. This is the first time I'm trying to root an android phone. Things are not going well..
I found a page in Indonesian with instruction on how to root my sister's Lenovo S890. My dad bought her one in China, we live in Europe.
We need to get all the Chinese stuff off and install a "regular" Android version with a normal marketplace (read: whatsapp and google and nothing blocked).
The page with instructions is at http://www.duniaku.net/2013/03/30/u...rtisi-internal-storage-lenovo-ideaphone-s890/ I used Google Translate.
What are the steps? First you need to set up some files such as drivers are required to carry out the process of flashing, SP Flash Tool version 3.1222 or higher, because Lenny chipset MTK6577 S890, S890 and file TWRP to also file a Super User and Busybox will be pushed into the system through TWRP. All the files you can download from the following link:
1 Download Driver Lenovo : Extract file. rar it and then click Install_Driver.exe to install drivers into the system. Rather long process, just wait.
2 Download SP Flash Tool : The author gave the newer version, which v3.1224.01. .
3 Download Team Win Recovery Project : TWRP file is specific to the Lenovo S890, so do not try for another Android, although it also MediaTek chipset.
4 Download Super User and Busybox : Will we push into the system through TWRP custom recovery. Download and copy directly to SD Storage / Memory Cards-mu. Place it outside the / root folder or USB Storage Storage SD / USB storage from your Lenovo S890.
5 Download Data Repartition : This file is optional, just download and place it in the root folder Storage SD / USB Storage. Can later be used to repartition the internal memory is too small Lenovo S890. Author will explain at the bottom.

I first installed the Lenovo S890 drivers. Clicked "Install anyway" for everything and rebooted. No problems.
But when I connect the phone it's still complaining that it can't find drivers (and I can't find any official drivers on the Lenovo website either)?
I also installed the MT6577 USB VCOM drivers that I found here http://forum.xda-developers.com/showthread.php?t=2206421 (before I did this the SP Flash Tool did nothing).
I enabled USB Debugging mode on the phone, and took out the SIM, the SD card and the battery when I connect it to USB to the PC. I am running Win7x64.
Every time I try to run (step 2) SP Flash tool, it starts downloading fine, but then Win7 'spits out' the phone (I can hear the 'usb device disconnected' sound) and SP Flash Tool obviously stops working then and gives some error.
I think this is because the MediaTek MT6577 USB VCOM drivers somehow refuse to install correctly? It looks like rooting might go well once this driver thing is fixed?
When I force installation of the drivers I get a Code 10 error and a yellow triangle next to the Preloader and the MediaTEL Vcom something USB driver in Windows Device Manager. ( I searched the forums and didn't find a solution for this).
I forced installation by opening Device Manager, click Add, click Add Legacy Hardware - manual - choose the usb2ser_Win764.info file out of the MT6577 USB VCOM drivers folder
This is what's in the .inf file : Is there anything I can change here to force it to work?

How do I stop Windows from ejecting the phone (force it to keep it connected as the MediaTek thingie that seems to work with SP Flash Tool?).
Or is there a better way to get an English Android version on this phone?
When I now try to boot the phone it says
tool dl image fail
uboot is blocking by dl info
Did I (soft)brick it??
Thanks in advance for all the help!!
Giving up
Since this seems to be a less popular phone with very little support available - I'm giving up.
Spent 3 full days on this thing with no results, and I just read the GPS also won't work outside of China either.
Now all I need to do is figure out how to get it out of META mode or Factory mode, and get it to boot back into it's normal Chinese Android system.

Hi, I'm having a much similar problem, since I couldn't flash recovery with SP flash tool, the process was terminated unexpectedly showing error message s_ft_need_download_all_fail (4050), after a couple of days looking for a solution I decided to format the phone with SP Flash Tool, and it worked, right after I tried to flas recovery again...and it worked. I thought I had found the way but when I tried to boot the phone in recovery mode nothing happened, no matter what keys combination I use, how long I press them, the phone just won't react, it doesn't show anything on the screen.
I don't know if this was the logic step to follow, but if you want to try and discover what to do next, up to you, 4 hands are better than 2,maybe yuo find the solution.
Good luck.
There is no button combination to boot recovery, try droidgram-reboot on play store.

Hope you guys manage to root it soon as I am one of those who waiting for it as I need to root my S890 also.

Hi Friends,
This is my first post at XDA.
I unfortunately bricked my Panasonic P81 after rooting it and adding XHalo app and the boot manager app from the Xposed Framework.
The situation is as follows-
I can get to the logo, it screams Panasonic and then doesnt boot. I dont have CWA installed and worse, my SD card which had my stock backup is also lost. This means I need a mechanism to stock recover and perhaps flash boot.img and recovery.img?
I am stuck at this point, not sure how to proceed. I can get to recovery, have cleaned cache, backed up user data ,done a factory reset. Even after factory reset it still cant boot.
Please help me with a step-by-step instruction to recover, this phone is dear to me. How do I flash?(boot.img or rom) I have downloaded Sagar Patel's (good bless him!) backup and the images, but need guidance on how to flash and recover.
Please help friends and apologies for any incovenience. I am still a newbie
Guys please help!!
Driver-USB-PC connection problem

Guys please help!!

Hope drivers are installed properly in your pc.
If you are going to use sp flash tool, Make sure SP flash tool is set to auto-detect com port, not manual selection
If you find that it is driver problem, following may help you.
Please note that there is nothing that much hard in driver installation as it is just to connect your device with your pc but because many users still face problem of driver installation, you can try following tricks!!!
It is observed by me that driver installation and adb interface problem do not happen in windows XP as eventually and generally it is happened in windows 7 and later…so, you can simply try on windows xp if you are able to do so…(you can use dual operating system too!!! Or good relation with neighbor/friends/colleagues/someone/all can be beneficial here!!!)
Note that all tricks here are not necessary to work, but it may still work for you….
Take one by one step, if the first step does not work for you, only then try next step. This is not all steps to be taken at once type guide…This is simply Try and error type tutorial/tricks…
There are following problems I have come to know regarding to driver installation and conflicts:-
Device is charging through usb cable but there is no usb option displaying on either device or no driver installation box/message/pop up appears in pc….
Missing sound of that usb-pc connection
Sound of disconnection after couple of seconds of connection
Adb interface is missing
Ok, sometimes changing usb connection type for example, from mass storage or mtp to camera, ptp, usb tethering or something else can bring adb interface…..
Try with different USB Cable. You can use original nokia or samsung tiny cable instead of cable having long length. Sometimes, length matters!!!!
Try in different USB Port.
Sometimes, you have to disable signature verification in your pc for proper installation of driver.
Had you disabled your antivirus before downloading, installing and while running your tools/softwares? You may need to do so…
Have you installed the software (or say, all associated softwares/tools) in C-System drive?, if not, then you should first install required software/tools in system drive that is usually C drive in Microsoft-Windows OS…or try after installing them on desktop.
Keep all necessary files/tools (driver files, flash tools, rom etc…) on desktop.
Download proper driver According to your model/device, According to chipset inside, According to Official site of manufacturer, Official site of chipset, through PC Suite/flash program of your device…
If the problem still not solve, you should try all available driver packages of your device one by one whether from official site of chipset inside your device, or any forum, adb, pdanet+ or foxfi, universal driver, VCOM Port driver, drivers from hexamob through play store, and find all possible packages and see if someone make positive result after installation…
If the problem still not solve, you should install remaining update packages of your system (PC) including all primary, secondary, essential, Non-essential updates….whatever, just install them all….reboot your pc…and see if problem is solved….
If you can connect the device but somehow found that device driver still not installed properly, just go to device manager in your pc, click on portable device, right click on your device and apply “Update driver”. Click on “automatically search” when a window prompt ask you.
If the problem still persists then,
Just remove all the drivers using usbdeview (I have given link also to download usbdeview in earlier post)
https://drive.google.com/folderview?id=0B511A2txfpAPbmwtQXZqbnVlT1U&usp=sharing
Install usbdeview and remove all the drivers
You can also fix this by showing the nonpresent devices in devicemanagement (google for show nonpresent devices for explanation)
Go to com ports, and delete all mediatek drivers except preloader driver. Now start over. It can help if you choose the same usb port where you had success last time.
Use Usbdeview to uninstall all the drivers before connection, restart the pc, Extract and keep driver zip files and other useful files/tools on desktop…just start your tool… and try to perform your tasks like backup…or restoring the backup…without worrying about that sound of disconnection you may listened after couple of seconds of connection or don’t even worry if you are just missing that sound of usb-pc connection….just try on your tool…
If still problem of driver installation persists, then simply use usbdeview and uninstall all drivers, restart your pc and try following steps:-
There are various ways to install proper drivers at the time of connecting the device with pc depending upon how you connect it.
Follow the procedure both with and without battery
Simply plug in via USB Cable
Connect by holding volume down button
Connect by holding volume up button
Connect by holding Power button
Connect by holding power and volume down
Connect by holding power and volume up
Connect by holding both volume up and down button

9. Select your driver there (select Mediatek Preloader USB VCOM Port)
10. Click Next and finish installing
11. If SP flash tool or other software still dont detect your phone then also install Mediatek DA VCOM (consider installing more from the list of drivers one at a time if need be)
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Case:-
It did the same thing with my MT6577 (Wiko Cink PEAX), so I connected it with a battery and without holding VOL+. Then "MT65xx preloader" appeared in device manager then disappeared (once). It is normal that it disappears. When you start Flash_tool and when you click Download (or whatever you want to do) THEN you connect the phone (in off state), and the flash operation will succeed.
Guess what? Once my Panasonic P81 could install driver and got detected after approx. 5 hours of continuous connection with win 7 x64!!! Meanwhile, I tried first usbdeview and then manually installation of mediatek driver but manual installation had failed as my p81 was only charging when it was connected with pc….So, mediatek – windows 7 conflicts….but, when I tried tiny (very small) nokia usb cable, it works instantly…
If you ever meet problem when you connect your android with your pc via usb cable and find that your android is charging but could not recognize or there isn’t that options of “USB connection” then just disconnect your android, power off it, remove battery, connect it without battery with your pc through usb, let it have some time to recognize your android or hear that voice of “usb connection” you were just missing…after that, insert battery and switch on your android…you are done!!!
Sometimes removing both sim cards and battery and then re-inserting them after a couple of seconds also works.
Try with different USB Cable
Try in different USB Port
Try in different PC
Sometimes windows XP works when windows 7 fails!!!
Use usbdeview to remove all the usb devices and then add your device

In my opinion MIUI is best because it has a self large community like xda and launch updates per month so many that you will fed up installing them.....if you download and install one update you will be amazed that it will say 3 more system updates pending......and if you complain a bug next month it got fixed.....only thing is to find one...
PS don't download the miui 6 for p81..complained by many p81 user that it hard bricked the device.
And that miui is not official i.e. some developer made his own one and DO not tested that it works or not......

Hi. It's been 6 hours now i'm trying to fix this problem but after tried more than 7-8 differents drivers, automatic, manually, read all different about it i start to be desesperate and i'm asking for help.
First, let me give you spec :
HDC S6 1:1 Clone
MTK6582
1GB RAM
4GB ROM
Android 5.02
I tried to download and install on windows 7 64 bits :
- "Drivers Google USB" manually
- "MTK_USB_VCOM_Driver_v1.1123.0_1" manually
-"Feature Phone Driver" manually
- "MT65xx Preloader" manually
-"PDANet" automatic exe installation
But even with PDANet i'm stuck here because it doesn't recognize the phone in USB Developper mode with USB debugging
Well well, TLDR : when i install drivers, drivers install but i got error 10 on hardware
Help, please
Problem solved. I installed these one and after the reboot it worked : MT6577 VCOM USB Drivers.
