Installing a custom recovery on the Samsung Galaxy Core is the only way you can install a custom ROM. A stock recovery doesn’t allow for zip file flashing, so it’s impossible to upload a custom ROM zip file without a custom recovery. Loading zip files isn’t all we can do from a custom recovery either. We can also take NANDroid backups — a new backup options that isn’t available any other way. With NANDroid backups, we can take a complete snapshot of the current ROM and backup everything, including saved game data.
Note that you do void any Samsung warranty you paid for when you bought this device. You cannot always just unroot by flashing a file through Odin to get that warranty working again, since Samsung devices often come with additional Knox security.
You should backup the device using the Settings > Wipe Date/ factory Reset option. The next screen will let you backup. You do not need to wipe the data before flashing a custom ROM, however.
