Killed Gt2560 after failed marlin upload?

Hello Guys,
i kind of killed my board. Firmware upload failed and after that i couldnt upload any marlin anymore.
Tried to flash a new bootloader with my usbasp and it finished the upload successfully. After that i still cant upload marlin via usb cable and if i try to upload marlin via usbasp programmer i get at the end the error that the port is not available. It finishes, but shows after all an mismatch error.
I tried to use an arduino nano as a isp flasher, but if i connect the gt2560 i get an error.
Is something burned on the board? maybe usb- connection somehow?
