If your Switch will not enter RCM, then there are two likely possibilities:That's not the problem. My switch can't boot into Rcm. The switch has a problem not my computer or tegrarcmgui.
Why i need tegrarcmgui when my switch is not in rcm mode.
- The battery is dead, in which case you need to charge it for a while before trying again (this happens occasionally to people when a system is accidentally left in RCM with AutoRCM installed).
- You aren't following the the steps correctly to enter RCM.
