FP4 stuck in a false EDL mode

Hi!

I tried to install lineage OS on my FP4, but somehow I manage to stuck it in a false EDL mode.

Now the phone won’t start in any mode. From what I red the only solution I have to unlock the phone is to make it switch to a real EDL mode with the testing points, but I don’t know where are the testing points and I’m affraid to kill the phone if I make a mistake.
Is someone here knowing where are those testing point?

Many thanks if you can help me.

Can you post a picture please? And there is no way to fix this on your own when you really only can boot into EDL. In this case you would have to contact support and send it to Cordon

Here is the picture I took were we can see some testing points.

I also found this document from fairphone https://www.fairphone.com/wp-content/uploads/2022/09/FP4_Information-for-repairers-and-recyclers.pdf
I think the testing point is 1109, but it is not working when I try.
