Any way to unbrick? (no video output, no safe mode)

Hello,

So after a bad flash my CFW PS3 could only boot to Safe mode. After another failed flash in Safe mode ( probably a bad HDD?) the device does not show any video output(HDMI or composite) and does not enter safe mode although the beeps are correct and the light is flashing green. I also tried without HDD. Any way I can fix this without a hardware flasher? Thanks in advance!
