Yup saw that before using it but on Amazon review people say they use it on electronics without an issue.
I only put enough to cover the pads with a tooth pick. I'll smear some on old PCB board to see if it'll do anything over time. It should be fine.
Looks like he heat wrapped a tiny SD carder into the USB cable itself. Pretty cool actually.
So to OP, the guy still has the SD card reader it's built into the cable itself. You'll fry your 3DS if you connect your NAND to the computer USB port bareback.
Dumped and wrote on my small N3DS with "SEC" NAND with the Kingston FCR-HS4 reader without an issue. About 2.8MB/s read speed.
Used the Oately #95 tinning flux from Home Dept, it made soldering a breeze.
The mic and home button stopped working after reassembly. You are not suppose to touch...
I understand that but if OP has to ask the internet to tell him which panel it is then it's not personal preference anymore. It's only personal preference if you can tell the difference yourself.
