My brother recently got a system update on his phone and it changed most of the settings of the phone and he is wondering if there is a way to get it back to the previous version

There are plenty of guides around on using Odin and a firmware from Sam mobile to roll back your OS.

You're assuming a Samsung device.

for the OP, this site has many sub-forums related to individual devices, some include root guides. Locate the one for the device in question and see if the info you're looking for is there.

A word of warning, any process that involves reverting to an older version of the OS likely will require a wipe of all data. In particular, what are the problems with the update? Sometimes a factory reset (also a wipe of all the data) can resolve some issues.
