Hello everyone,

Today I am going to show you how to flash CWM recovery for your a800. The process is very simple and fast. So I'm just going to start with the tutorial.

Things you need:
1) XOLO A800 with either ICS or JB 4.1.1.
2) SP Flash tool from here:

3) VCOM drivers:
Drivers for XP/WIN7 -->http://www.mediafire.com/?cypm22rgs2k83ji
Download MT6577 USB VCOM Driver (W8) -> http://www.mediafire.com/?7yee2of64nhl947
4) MTK 6577 scattering file from here:

5) CWM Recovery from here:

Download all the above files.
Now you need to install VCOM drivers so that your phone can be detected by the flash tool.

Installing VCOM Drivers:
1) First switch on USB debugging mode from the developers options.
2) Switch of your phone completely and do not connect the phone to the pc yet.
3) Open Device manager of your computer and leave it open.
4) Now connect the phone with your battery inserted. You will notice the device manager refreshing and a MT65xx preloader as shown below. This means the drivers need to be installed.

5) Now launch the installdriver.exe from the unzipped MT6577 USB VCOM drivers folder. Confirm the installation of unsigned drivers
6) If there are any warnings in windows 7, just accept and install.
7) Reboot your PC
8) Open device manager again and connect your phone in switched off state. You will see device manager refreshing.
9) A mediatek preloader USB VCOM driver appears for some seconds and disappears.

10) Before the driver disappears, you need to click on it. The properties of the driver appears. You need to select update driver which is under the tab driver.
11) Select files option and navigate to the folder where you extracted the mtk6577 VCOM drivers.
12) Choose WIN 7 or windows 2K_XP_COM (depending on the OS you have running on your PC) and complete the installation.


13) That's it. Now you have to REBOOT PC and go on with the next step. 

Flashing CWM Recovery
1) Open flash tool folder and start sp flash tools by right clicking and choosing run as administrator.

2) Click on scatter-loading and select the MTK6577 scatter file which you downloaded from the link.

3) It will show the various options which you can flash.

4) Now you need to click on recovery and select the CWM recovery which you downloaded. it will be named as recovery.img (ONLY RECOVERY SHOULD BE TICKED)
5) Now press download button. It will pop up a warning message. Don't worry and click YES.
6) Connect your phone and let the process get over.
7) It will show a green circle saying finished.
8) That's it. Now you can switch on your phone with CWM installed.
To enter into CWM recovery, switch off your phone until it vibrates. Then hold Vol+ and Power together till you enter CWM recovery.

    3. Yeah the drivers are installed. Just flash the cwm recovery now. The software will automatically detect it when you connect it when the phone is off.

    4. The drivers appear only for a few seconds. Don't worry about that.

    1. The drivers aren't installed correctly. You need to make sure that yellow triangle in device manager goes away. Once the drivers are installed, it will recognize it and then it will disappear. That is normal. But first make sure the drivers are installed. If still having problems, message me on google plus and I will install the drivers using team viewer. :)

    1. Glad to help. :D Do cool stuff with your phone. :) and don't forget to install Greenify. It improves phone performance and battery to a huge extent. You don't need any clean master if you have Greenify. :)
