Thanks guys. It worked for me by covering the head. The hdd is now detected by bios. I will check now if the data is untouched, but it should be. I really appreciate your help and effort. Many thanks!

It is a ST3500620AS drive. Maybe it will make a difference to cover the head and not the motor during the first steps. What do you think?

Thanks so far guys. I repowered, but when I restart the drive, I get the "LED:000000CC FAddr:002490D" Message in the terminal. Seems like this is a problem for HP drives (I got one with the HP24 firmware on it). So I cannot access the drive. I just can disconnect the PCB again and do all the steps from the start, but it still get stuck after the last step. Any ideas on that?

You are right, I didn't do that. Ok, you are talking about powering down by removing the SATA Power Cable, right? I thought it is not recommended to that if you get stuck within the last step.

Hi guys, just tried to unbrick my Seagate drive. I got stuck after the last step. I put in "m0,2,2,0,0,0,0,22" and am now waiting for more then 15 Minutes, but there is no output. What can I do?
