1. hold power 15secs
2. leave the jig out and just power 2secs
3. if just blank screen you're in rcm mode
4. plug in pc load a payload with tegrasmashgui
EDIT. do you know if it has enough power to boot? try boot normal or boot the hekate payload
i was finally able to get my switch in rcm mode by following what you said to make sure. but now im having issue of it not being detected when i plug it into my computer. tried using different ports on computer
