If you manage to short the wrong pins in the Joycon port, there is a possibility that you can destroy the circuity for the port itself, or even the entire Switch console. The first is irreparable damage to hardware.Just as a warning – modifying your Nintendo Switch can result in a few bad things. A copy of Notepad++ for editing text files ( DO NOT use Windows Notepad).A Windows PC capable of running the RCM injection software as well as possibly other software for converting XCI to NSP images.A USB Type-C to USB-A cable for connecting the Switch to a PC.Larger is better, ideally 64GB or 128GB would be best. An microSD card, at least 32GB in capacity.A microSD card to SD card adapter / USB SD card reader adapter to read/write to a microSD card using your PC.An RCM Jig, modified paperclip, or another way to short pins 1 and 10 on the right Joycon port.An exploitable Nintendo Switch that was manufactured before July 2018.To follow this guide, you’ll need the following items. Around July 2018, Nintendo created a new hardware revision of the Switch which fixed this flaw, but the original run of consoles sold like gangbusters, so there are a lot of fully exploitable Switch consoles in the wild. For those of us who bought a switch before around July of 2018, this means that our consoles are fully exploitable. Because of that fact, the original run of Nintendo Switch consoles can not be patched to fix this exploit via software. Unfortunately for Nintendo, this is a hardware problem and not a software issue. This is a fairly common exploit for nVidia ARM-based devices (of which the Switch is one) and has been used before to gain root on various Android tablets and phones. Once in RCM mode, a payload can be injected in to the Switch before boot to allow it to run unsigned code. A flaw was discovered in the hardware of the Nintendo Switch (namely in the nVidia processor) that allows the unit to boot in to RCM mode by holding the VOL+ button and pressing Power on the console, if pins 1 and 10 of the right Joycon port are shorted. Explanation of the Switch’s Hardware VulnerabilityĪlthough not a totally new thing, the Nintendo Switch hacking and home-brew community has blown up over the past 6 months.
