GS752TPv2 Ports down, aborted boot sequence

I have a GS752TPv2 that powers on. But no connectivity on any port.

I connected a TTL-USB and Link up with TeraTerm into the serial console see logging attached.

I have send FW V6.0.6.2  binary over ymodem to flash and wrote them to RUNTIME1 and RUNTIME2 after reboot same sh... than before.

How can i fix the Problem? Whats goes wrong?
