what does flashing via fastboot actually do?

Hi!



If I modify files that are in the root "/" directory, e.g. create new folders, modify chmod, delete files etc., if I flash the stock rom via fastboot, will all partitions and files in the "/" directory be restored? Or will the flash restore only some partitions?
 
On all devices released in the past ~4 years, "/" is in fact the system partition (known as "system-as-root").
Flashing either a recovery ROM or a fastboot ROMs will overwrite the system partition, hence "/".

I understand, thanks for answering, one last question, "/" is modified by the user? example with OrangeFox, I can create folders in "/" and put the files I want? if I reinstall the miui via fastboot, the changes made by the user previously will be deleted right? example chmod?

You can't touch anything on any read-only system partition. If you try, you can end up in a boot failure.
