no chime / unresponsive to entering recovery mode etc after sudo nvram
I upgraded my A1502 with a NVMe/PCIe SSD (version without adapter which fits directly). was working fine had some sleep/wake failures sometimes so I read through some forums and tried some pmset adjustments in terminal
After auso nvram enable-legacy-orom-behavior=1, nothing worked anymore.
- SMC/NVRAM reset does not seem to do anything
- Booting from old original SSD with Catalina which was working perfect does not work
- Entering safe mode/recovery mode does not work
- Completely removing SSD and only starting from catalina usbdrive doesnt work
I get no chime nothing, just flashing question mark folder after a while. Is my logic board fried or whats up?
Ist dies eine gute Frage?

It seems you bricked your Mac for good. Where did you dig out that "auso nvram enable-legacy-orom-behavior=1" command from, just out of curiosity ?
