Hacking Hardware Switch OLED Picofly Issue: Error 2016-0641, SD Card Not Working

[Jagovi]

Hi everyone,

I recently installed a Picofly modchip on my OLED Switch using the Kamikaze method. Everything went fine, and the console was working great for two days in both OFW and CFW.

Last night, I left the console installing some games using DBI, but this morning, I found an error on the screen: 2016-0641. Now, it won't recognize any microSD card, which means I can’t boot into CFW. It does boot into OFW, but the error still shows up.

What I’ve Tried So Far:​

• Swapped the SD card reader with another one from a working console. Still the same error.
• Tried several different microSD cards (formatted correctly). No luck.
• Removed the Picofly modchip completely. Checked everything, and it looks fine, but the issue persists.

Any idea about something to check?

Check your SD reader pins diode

Check your SD reader pins diode

The values looks similar except the second and the last point (From left to right).



And it wouldnt be GND.... Where does that signal come from?

Update!

I see that the pin 9 (grounded) go directly to the CPU. So I made a reflow and it is working again.
Thanks!!!
