Thanks a lot! I made 2 mistakes:
1. First I tried flashing without connecting the 12V power. For some reason one of my USB cables actually gave enough power so that some LEDs flashed and I thought that is sufficient.
2. When I connected the 12V power supply, I did not connect the wires to the terminal properly, so I thought it was powered up but actually it was not

Thanks for your prompt reply!
Will start tinkering now
