my problem was that i was wiring my cartridge reader on the wrong side. YaYa's image helped me a lot. It was able to have it boot from the cartridge a couple of times, but then the sd card corrupted

. When i tried desoldering the wires to change their length, I stopped getting any image(no activation light either) even when i put the sd card directly into the sd card port. When i put the sd card in a different pi, it still runs (is still corrupted tho :/ )). I think i overheated the pi zero and now nothing will boot from it, even when i hook it up to my tv.
