I just updated to 8.1 with the new SX Installer and for some reason the switch won't boot. I'm using my USB with TegraRCM and it says it sees RCM mode and has injected the payload successfully, but the switch itself isn't responding.

I have the newest payload on my PC and the newest boot.dat on the microsd. IDK what I did wrong or how to fix it.

The two common issues with not being able to boot after a firmware update are themes, and outdated boot.dat

I assume the switch still boots to sysnand?

Double check your titles folder and make sure that there are no xxxx1000 folders I believe those are theme folders. Can't hurt to check. Only other thing would be corruption. Are you running emunand or booting to the sysnand?
