Problem whit argn one M2 base (firmware missing)

I have a problem whit argn one M2 base …
today I tried to insert a new firmware but the operation was not successful.
now the controller no longer sees the SSD
is there any way to reinstall the original firmware?
does anyone know where to download a guide or software to restore original operation?
thanks in advance for helping me

This is not a Argon ONE M2 issue… this (from your description) is a raspberry PI issue. There are a number of guides on the internet that can be used to help get your system back up and running.

Perhaps a better explanation of what you did would help?

It appears you mean the firmware for M.2 SATA Board?
