Also you might select Show all devices from the device type selection window.The flash memory of MT65xx devices with an unlocked boot loader can be reprogrammed in a way that a software ( SP Flash Tool S mart P hone Flash Tool for example) can write data to it between specific points (also known as memory blocks).
These points in memory are contained in a file whose name includes scatter, file which must be loaded in the SP Flash Tool. Based on this file, the software will then look for the required components in the same directory in which the scatter file resides, listing them afterwards. If your device was alive before you removed the battery or shut it down (I mean not bricked), In the Device Manager window the unknown device MT65xx Preloader should show up. After 5 seconds the MT65xx device will automatically close the communication interface and the MT65xx Preloader will be gone until next time you connect your MT65xx device to the PC. Mt65Xx Preloader For Driver By IndicatingMt65Xx Preloader For Install The DriverUse the second option to manually install the driver by indicating the driver directory. Browse to the extracted folder MT65xx Drivers and select the folder corresponding to the version of Microsoft Windows that you are running. That is of course if you got the driver named MediaTek PreLoader USB VCOM Port (COMx) installed and showing up under Ports (COM LPT) in the Device Manager window, as soon as you connect your device to the PC. This also means that the device driver that you have installed at Step 7 was correctly recognized. In normal circumstances, with the battery pack inside, the Integrated Circuit within the MT65xx device will begin to charge the battery after 5 seconds. Mt65Xx Preloader For Download As BeingThe SP Flash Tool will report the download as being successful but your MT65xx device will not start afterwards and neither will the SP Flash Tool be able to download the firmware components again because the normal MediaTek PreLoader communication interface will not start unless the SP Flash Tool will first send a good PRELOADER firmware component. If this PRELOADER firmware component was previously downloaded to the Flash Memory of the MT65xx device but it was incorrect or corrupt, the MT65xx device will use a special, low-layer interface, to communicate with the PC. This interface is non-removable and is the only interface that allow us to change the PRELOADER firmware component if intended. However, the SP Flash Tool can only use this low-layer download interface to replace the PRELOADER component of the firmware. Afterwards, with the correct PRELOADER firmware component, the MT65xx device will instantly reinitialize its related Integrated Circuits, switching to the normal MediaTek PreLoader download interface that will take in the rest of the firmware components sent by SP Flash Tool. You only need the right driver to start the recovery process of the Flash Memory. The proper driver for this low-layer download interface is also located in MT65xx Drivers folder. The MT65xx device will keep the low-layer download interface alive for about one minute. If this is the case, you must then manually force-update the driver for the low-layer download interface of the MT65xx device. The device is sometimes with an exclamation mark and it disconnects regularly being unable to start. That was because my PC was set to automatically search for drivers at Windows Update for all the new connected devices, so I expected this to happen. A simple method to avoid this scenario is to disconnect the PC from the internet before connecting the MT65xx device to that PC via USB. Otherwise you might have a hard time finding the device in the Device Manager window.
