Editing Nintendo Switch Trinket Guide (section)

== Troubleshooting ==

* I accidentally updated and my Switch receives an error when trying to boot! Disable autoRCM as mentioned in [[Nintendo Switch Trinket Guide#Updating Horizon (Advanced Method)|this paragraph]].
*Nintendo Switch does not boot and has a black screen

The modchip is likely not attached correctly, while AutoRCM is enabled. Check one of the following straps: 3.3V, GND, or DATA+/DATA-.

* Nintendo Switch boots stock, but not into RCM payloads

One of the DATA+/- are not connected.

Alternatively, the modchip could be short-circuiting with the metal RF shield on the back of Nintendo Switch. Please make sure to properly shield the top of the modchip and the wires connected to it.

Alternatively, the 3.3V line is not connected.

* Nintendo Switch does not enter RCM!

Has the hardware been modified recently? Please check the Joy-Con's rails, both the inside and the outside. The outer parts may have dust or debris covering the metal contacts. If not, the user's jig may also be dirty. If both of these are correct, then it's likely that the ribbon cable of the Joy-Con slot may be slightly torn, making RCM entry impossible without removing the NAND.
