When I open hekate on my Switch, it keeps saying it's in 1bit mode. Which is funny because it reads the card no problem at least NOW it does and I haven't had this issue until just recently nor have I done anything to the pins. I'd open it up if to check if I could but I don't even know what screwdriver the Switch uses and I'm afraid of damaging my Switch.
This has happened ever since i upgraded to 14.1.2 and then 15.0.0 and while my Switch works normally otherwise, I'm getting more worried by the minute. It happened with my 1TB SD Card all of a sudden and before that It never happened with any prior cards. The card is Sandisk too. I think it's an issue with the sigpatches as I just installed them.
Update: I tried a rather unorthodox solution by searching the forum and found that if I apply pressure to the sd card reader it will sometimes go past the original check. Unfortunately this leads to other problems, like my Switch not wanting to accept hekate, and I feel like I've exhausted every possibility besides taking it apart, and I really don't want to do that. I just know some people said on this forum that if the pins are even slightly loose it can mess things up big time. As I said this is ONLY when trying to use CFW, everything else works perfectly.
