Hi everyone!
Recently i had to open my switch, because it froze. (i was trying to load shofel2)
None of the reset methods worked, and the battery was on full charge... So i decided to open it.
Everything went fine after reconnecting the battery (it was booting once again to OFW).
I noticed that one of the pins were missing from the SD FPC, and sure it wouldn't read cards. The missing pin was stuck on the slot's connector, so i soldered it back in place.
After cleaning the solder paste, it was booting to CFW. After a few minutes, it went black. I learned that my new solder paste is conductive, and it was stuck under the nearest buck converter. The chemical reaction ate away the pads on the IC. Without the IC, it shows Nintendo logo, boots into payloads etc.
So...
What does the MAX77621 buck converter supply which is near the SD FPC? The GPU?
