如果您的目标只是升级路由器的当前固件，保持相同的版本（例如，24.10 或 SNAPSHOT），那么只需使用 upgrade 命令即可。 如果各种预构建检查发现了任何问题，或者在构建过程中检测到错误，则升级将中止，并显示一条指示问题的消息。
请牢记开始的第一步是
备份！
图形化备份：网页（Luci）转到 系统（System） → 备份与升级（Backup/Flash firmware)。 单击 生成备份（Generate archive）。
命令行备份： 复制粘贴后运行该命令 sysupgrade --create-backup /tmp/backup.tar.gz 然后使用 scp 或其他工具将文件复制到安全位置（通常是另一台主机）。
不要问为什么，跟着做！
如果 owut 发现软件包降级, 或者自上次升级以来没有进行任何更改，它会告诉您并停止. 您可以使用 --force 选项重新运行该命令，该选项将继续构建和安装，保留所有配置。如果你需要使用 -force 但你又不确定的时候，请在论坛中提问。
请注意， owut 目前仅在主线 SNAPSHOT（测试版） 或 24.x 之后稳定版上可用。
$ opkg update && opkg install owut # 在 24.10 稳定版。
$ apk -U add owut # 在主线测试版。
$ owut upgrade
