High Success Rate When Attempting Downgrade With sysUpdater
Now either back up the 'boot.3dsx' or rename it, as long as there is no longer a file with the name mentioned on your sd card. Now rename the 'sysUpdater.3dsx' that you placed on your sd card to 'boot.3dsx'.
大概意思修改'sysUpdater.3dsx 为'boot.3dsx' 放到tf的根目录 直接进入
建议还是先替换1月5日的sysUpdater 的测试下 本人为测试 只是搬运
