is there a debug interface, where i could capture some output?

@AnotherElk

please have a look at the topic FP3 custom rom development based on released source code .
Search the topic for “uart” … they got it to work.

checked voltage of the battery: 4.27 V.

• That battery voltage is fine. 4.27 about 90% charged.
• There are two white squares and both on the core module

  The one you see is on the core module, is the one on the left of the image above

As far as replacing the bottom module. I’m not sure but the with a good battery I’m sure the phone would start without the bottom module. After all failures of the bottom module happen and people worry about the battery going flat before they can replace it.

So there’s no fairphoneangel you can ask for assistance ?
