Is it possible to reset an install without reflashing?
What (hardware) platform are you talking about?
I’ve only ever read
in some router and/or phone context.
btw: poor choice of username
meaning can I reinstall the system without reinstalling the OS from scratch
btw: glad you like it
there is no “factory reset” like as on phone or also maybe windows 10, mac…
the only way to have your system like as after a fresh install is to install it again or restore a backup you did yourself.
