soooo, my GW was faulty from the start. it was one of these that gave some error when trying to update its firmware. one day, I asked someone to resolder the faulty pin. even after that, it wouldn't update, but the next day it did on the first try (this was a year ago, or even more. a few minutes ago I force-reupdated the firmware and it worked on the first try). problem: from that day, the GW card started to not recognize consistently the microsd card. I gave up trying to play with .3ds games a year ago, and then played some other games on the PC. one week ago or so, I wanted to play a certain game on the 3ds, so I tried to put some tape in the GW card to force the pins to make contact. it worked... until yesterday. all of a sudden, while I was playing, the black screen with "hold the power button" appeared. now my gateway won't recognize the microsd card anymore. it's "read error" every time, which is the same it gives if you don't have a microsd card inserted in the GW. this is clearly an hardware issue (don't even bother telling me to try changing microsd card, reformatting, etc., I already tried all that, and it's evidently the GW card's fault anyway) but I need help to locate which pin/s could be the culprit/s. I dunno, maybe there are some experts around that know which pins do what. the pins on which I put the tape are the ones on the right side, the same side of the pin that got resoldered. related post(s), with images of the card after the soldering (inside the spoiler): http://gbatemp.net/threads/keep-get...to-install-gateway.369810/page-2#post-5119780 in the second image, you can see a pin that looks really off. it seems it was already like that, but I'm not 100% sure. anyway, in that week in which the tape method worked I didn't touch that pin, so it's unlikely to be the culprit. thanks for the help. edit: of course I can't get a replacement.
