起因
年初那会放假在家没事干，给n1刷了Armbian装Docker挂DDNS给内网设备做IPv6跳板（详情），挂了没几天就开学，索性给拔下来了；到学校鼓捣那个小米路由器R3G（很好玩，之后要开一章讲校园网单线多播叠网速）；在毕业前稀里糊涂有了份家附近的工作，天天回家折腾大学买的那些个b设备，目前的主路由是中兴 G7615，这个不允许我随便折腾（妈：“咱家咋又没网了？！”），R3G也还是学校的那套Immortalwrt，在我犹豫该给n1刷什么系统时看到了一篇知乎，随后还是决定刷Immortalwrt
固件
刷入
和Armbian那套一样，由于盒子默认U盘的启动优先级高于eMMC，直接插上通电就行，但要注意盒子默认ip是192.168.1.1是否会与主路由冲突请自行考虑
Name Value
Default IP 192.168.1.1
Default Account root
Default Password password
Default WIFI Name OpenWrt
Default WIFI Password None
官方写的安装教程
For the Amlogic and Allwinner platforms,
use tools like Rufus or balenaEtcher to write the firmware to USB,
then insert the USB with the written firmware into the box.
Browser access to OpenWrt's IP (e.g. 192.168.1.1) → Log in to OpenWrt with the default account
→ System Menu → Amlogic Treasure Box → Install OpenWrt,
select your box from the dropdown list of supported devices,
click Install OpenWrt button to install.
如果冲突了建议直接连n1广播的wifi先进行刷入，再配置下静态IP就好了
突发状况
刷上固件以后发现openwrt的官方源和镜像源都更新不了，查，“11月15日OpenWrt宣布，主开发分支Snapshot和未来的Stable Builds将切换包管理器，从opkg更换为apk。”，虽然但是，tmd说是能提升性能，但这玩意儿不是刷好配置好了就扔那不管了吗，谁天天没事干拔软件装了又卸啊，
暂时切回stable版的镜像源（虽然刷的是快照版
