Installing Driver

First try the Alternative Driver, which is the AutoInstaller. Just open the install.bat then it will automatically install the driver. Then proceed to flashing. If it did not work then proceed with VCOM driver that you had downloaded. Then install it manually follow the guide below.

For Invalid IMEI:Your Phone/Tablet must be rooted first
Restore yong IMEI in MTKDroidTools version 2.5.3. You will have this error when you format your phone in Flashtool as I had experienced. To restore download MTKDroidTools version 2.5.3 After you extract the file. Open the green robot, you must enable the usb debugging in your phone. It is usually located in Settings>Devoloper Mode then look for usb debugging. After enabling it. Connect your phone in your computer then in MTKDroidTool click on ROOT. Wait for it to finish, then Click in IMEI/NVRAM, input 15 number in each box. Then click REPLACE. Then click Reboot or you can manually turn off your phone. Then turn your phone on again. You can see that you have fully restored your IMEI.
