Installation of the USB VCOM driver:
 With USBDeview, clean up your PC from all possible old MTK VCOM entries, then reboot your PC.
 Smartphone is switched off, and still dont connect via USB to the PC.
 Open Device Manager and leave it open!
 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 MTK6572 Smartphones should be installed without battery. Please before hand inform.)
 now launch the Installdriver.exe from the unzipped SP Drivers MTK65XX-Windows 7+Vista+XP drivers folder. Confirm the installation of unsigned drivers
 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!
 PC reboot!
 Open Device Manager and open the switched-off Smartphone via USB to the PC release, now connect (same USB port!)
 Now a MediaTek PreLoader USB VCOM should appear for a brief moment in the Device Manager entry!
 At the moment the entry double click and click on "Update driver" under the tab "Driver".

MT6572_Android_scatter_emmc.txt(located in the downloaded Rom) for your device and ignore any message that may appear.
- Turn off your phone, remove the battery and replace it after some seconds (and don't turn on the phone).
- Press F9 (or hit Download button) and connect your phone into the computer via USB data cable.
The process will start and a red progress bar will appear.
- After the red progress bar is complete, there will appear a purple progress bar.
- Right after the purple progress bar is complete, a message will appear underneath it:
“Please insert USB cable in x seconds” and then the download will start right away (you will see the yellow progress bar filling up).
- When the yellow bar is complete, you'll get a popup with a green circle and Download OK message,
which means that the process has been successfully terminated.
- You can now safely disconnect your phone and turn it on. The process ends here.
Attention: Please follow the instructions carefully. I will not take any responsibility on whatever may happen with your phone.
Very important warning: Always make sure that you trust the sources of the ROM you download and know that it is meant for your phone.
After flashing a wrong preloader, your phone will be completely dead (can't be powered on, it will not charge and won't be detected anymore by the computer) and there is no way to recover it.
※Please make a backup of your device before installing or updating ROM
