Do you know anybody with the same device around you?
If you do, you can backup the firmware and flash to your own device.

Follow this carefully and respond
Flash only preloader from each of the 4 firmwares you have.
After flashing each preloader, open device manager on your PC, just connect your phone to PC without doing any other thing, and see if your phone is recognized as "MTK usb Port" or "Mediatek Preloader xxxxxxxx".
