Just updated to 8.1 through SX Installer and now I'm stuck in RCM Mode. I can inject the payload and TegraRCM says it's done so successfully, but the device isn't responding. IDK what's wrong with it. I have the newest boot.dat, payload.bin, and got the 8.1FW files from SXOS' forums. Ran the installation just like it said to. People suggested injecting twice but that hasn't worked.
