SafeSysUpdater is a system downgrader for the 3DS. It is a fork of sysupdater which supports 2.1.0 downgrading, 9.2.0 downgrading, GPU based memchunkhax2 for stability increases + <=10.7 support, and fixes some of the outstanding issues.

Note: This project has been replaced by sysDowngrader 3DS.

Features

  • Automatically load update information (needed files, md5) based on your 3DS model and region.
  • MD5 check all the cia update files before downgrading.
  • Can check your update files without actually downgrading.

Installation

Put SafeSysUpdater.3dsx somewhere you can launch it.

Put your downgrade pack as usual (/updates/*.cia).

Launch it multiple times until it pass the black screen (hax).

If it freeze just after you press Y to downgrade or "init ->" more than 1 second, restart.

See also the release thread and tips to prevent brick.
