Words of caution!

Every time you change something on the device you assume some risk that something could go wrong!

You take a calculated risk on your own mind voluntarily, I'm not responsible for any damage!

Make Sure that you have a charged battery at least 80% before you start something like that!

Never stop the process after it starts running!

It is important that you work according to instructions, if something is unclear ask them before you make an "educated guess" !

There is nothing between the external appearance of the device and its actual characteristics (for devices made ​​in China), two devices that look identical externally may be completely different (for example: Star x18i and HD7000, one is 3G the other is not, etc.)

Make sure you use the correct version to what you have on the device (eg 2.3.4 or 2.3.6)

Instructions for installing the drivers for full support on all stages:

* Do this before you try to update version (ROM \ Firmware \ Update whatever you call them ...), and not while you'r doing the update!

* Extract your files from "MT_USB_VCOM_MT???? _Android_Drv.rar" to a folder,

* From an off state with the battery out of the device, connect it to the computer through USB cable, let the computer try to identify the device, if it is detected and installed skip forward, if not, choose to install the driver manually and point to the folder where you have extracted the the "MT_USB_VCOM_MT? ??? _Android_Drv.rar ", if everything is OK, skip forward, if not you should get a different version of drivers,
