s905l3b的arm fnos出来了，忍不住试了试，终于在创建存储完成后，盒子不能启动了，再插上刷入飞牛的U盘也启动不了，变成了传说中的砖。在网上找了很多资料，尝试了很久才救活。下面是整个救砖过程的记录。

软件准备

  • adb
    adb工具包。
  • amlogic_usb_burning_tool
    安装刷机程序。
  • arm fnos刷机包
    解压出.img文件备用。
  • 【全网通】天邑TY1612-TY1613_S905L3B_非高安_安卓9.0-通刷-线刷固件包.zip

    【全网通】天邑TY1612-TY1613_S905L3B_非高安_安卓9.0-通刷-线刷固件包.zip
    解压出.img文件，用rufus写入U盘备用。

刷机救砖过程

思路：先线刷安卓9，再从U盘启动fnnas。
之前漫无目的找s905l3b的刷机包，一直不成功，后来看了眼盒子背后，有个标签，写着盒子型号是天邑TY1613。接下来以天邑TY1613为关键字寻找，思路就清晰了，很快就找到了底包，包中就有刷机过程，只是没有晶晨短接神器，需要手动短接。
底部标签：

短接点：

这里用的短接点1。短接操作比较麻烦，最好再有人帮忙用usb连接电脑。此处费时较多，因为短接点很小，多次重试才成功。
打开amlogic_usb_burning_tool ，导入刷机包，点开始，用摄子夹住短接点，再用公对公usb线连接电路板和电脑，正确了就有提示音，刷机进度条开始走动，到7%时马上松开短接（夹的时间长了会出错，重试了多次，见图上的红色出错提示。），等进度条走完，刷机完成。

盒子接电，插上网线，启动完成后，在路由器后台可以看到有新设备接入，记住ip。

刷飞牛

把写好飞牛固件的U盘插入usb2，cmd进入adb所在目录，运行：
adb connect ip
adb reboot update
成功后盒子会自动重启，再从U盘启动。
等启动完成，从浏览器访问ip:5666，会进入飞牛os的设置过程，设置好用户名和密码。
cmd运行ssh或用xshell软件连接盒子，
连接后提权运行fnnas-install，把飞牛写入emmc，这样就可以拔掉U盘，盒子自已运行飞牛。
安装过程中按盒子类型，输入id: 130。进度完成后拔掉U盘重启，飞牛就在盒子上运行起来。
fnnas-install的输出：

不能ota更新的话，就只能写入U盘再刷进emmc。

刷机就要有成砖的觉悟，也要有救砖的能力，成功了也是很有成就感的。
