I loaded up a past backup and no change
Do you mean a backup of the SD card?
Does the screen stay completely black or does it faintly light up?
In case it lights up faintly,it is in autoRCM mode.
then the Switch is waiting for a payload to be injected.
To turn off the Switch forcefully, press the power button for 15 seconds.
Also check your USB cable.
Especially that the data transfer is working besides the power.
A broken USB cable kept me busy for a few hours once.
If you have an additional Switch, also check that tegraRCM is working correctly.
If you left your Switch for a while, it might have drained it's battery.
Leave it for 15 minutes with the charger connected.
I recall that if the battery is completely drained, the Switch doesn't boot.
With any version of lockpickRCM you can check if injecting works or not.
lockpickRCM doesn't have any dependency on the SD card to boot.
