    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

    You have to root your phone if you want to downgrade your phone.

    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.

    Depending on which phone he has, he may be able to downgrade without rooting. It would help if you identify the phone, carrier and OS.
