I have already tried replacing the power volume ribbon and it is still not working. Volume- and power button are working fine. Is there any other way to enter RCM? Or any other fixes I could try? Thanks!
I resurrected my account to just say thank you this saved my switch. I had auto RCM on because i botched the on board volume + traces on my switch so i couldnt utilize my rcm jig. I unplugged the battery and the EMMC. Connected the battery and powered the switch on grabbed my usb c cable and connected to my pc and launched TEgraRCM. BAMM!!!!!! green in RCM mode. Pushed payload and re applied auto rcm. We back in the game baby!!!Have you checked the pins at the motherboard to verify that the ribbon is indeed working? You should be able to short the pins at the connector with a tweezer.
Another alternative is to unplug the battery, unplug the emmc, re-connect the battery & power on. Without the EMMC it will always go to RCM. You can carefully hot plug the emmc after getting into Hekate.
