Can you post a picture of the other side of your SD card?
Here it is, ty :D
Sorry, I meant the underside of the sd card adaptor itself, so I can see which SD card pins go where.
NP :lol:

Heh, still not quite. :) The underside of the Sandisk Micro SD card to full-size SD Card adaptor to see where the wires are soldered there.

Hope it's clear enough.. Ty chief!

UPDATE

I've cutted the connection of the pi0 to the cartridge reader so u can tell me where i have to connecti the pinouts of the pi0 in relation to my sdadapter "cartridge"

other way is to get a multi meter or use a 3v button cell battery and an LED and just check each pad track for shorts so if the led light up. move the wire to another pad

I'd take a multimeter (or a coin cell battery + LED like @DirtyBullets suggests) and double-check two things: that you don't have any bridged connections, and that you have good solid connections everywhere you are supposed to. Also clean off the pins on the cartridge really well.

You said you disconnected the cartridge reader from the pi. Does it now boot with that same SD card? You mentioned before that it didn't work even with the SD card directly in the pi, but I'm assuming that was with the cartridge attached (which could indicate a short or something somewhere).

If all that checks out, then you might want to put a 1uf capacitor on the 3.3v wire somewhere (right next to the pad on the back of the Pi would probably be easiest). [EDIT: See @prerunnerseth's note below] This is called a decoupling capacitor and helps remove interference caused by the 3.3v line. Shoutout to @prerunnerseth for educating me about this. :)

The decoupling cap needs to be closest to the card.

There was a short... Now it boots up

EDIT: I'll redo connections (scratching off traces onto the cartridge pcb) on the card and control if they are solid then i'll update here, thanks for helping guys
