Ok, it sucks.
 
  Flashed Coffin to CF with the new adapter, same problems.
 
  Looks like my Vampire card is faulty.

Which core speed do you use?

Did you apply the CAP fix needed for V600 ?

I'm using x10.

I have not applied any fix. I did not know  about this. What is the fix exactly?

There are 2 important caps on the V600.
They are labeled C3/C6 and are SMD in 0805 size.

Since GOLD 2.7 having FPU and super fast memory controller the core needs more power.
We recommend to add a 2nd CAP on top C3 and C6 to improve power stability.

PLEASE not remove the CAP.

Just add on top, in addition.

Please only do this if you are experienced in soldering!

But its not that difficult, my son 10years did it successfully for his V600 too.

I would add on top of each C3/C6 an SMD CAP with 22uf/10V.
If you have no 22uf two CAPs each 10uf would be the same.

If you have no SDM caps - a normal Elco Cap added parallel with 200uf or so would also do the job too.

Thanks, will try it - possibly tomorrow and report back.

  I soldered 2 200uf 10V capacitors on C3 and C6, like in the video.

  Nothing has changed, still having the same issues :(

Now, it's either the Vampire card or the CF card. I'm using this SandDisk:

I could try another card, but I don't feel like spending 30 euros on it, possibly without success.

Is anone using the same CF card?

Try deleting the file StonX_modes from Envarc:

This helped, thank you.
