HI
If i am right, you used the bios.bak file to flash to older version? If yes, then you have bricked your mainboard and need to replace it. You can contac lenovo service centre for the replacement.
The reason is simple that downgrading bios should be done in dos conditions only.

The thing is that the laptop is completely dead. Any recovery method wont work. You can contact the nearest local technician so that he can propose a solution
