斐讯N1救砖记之TTL大法【亲身经历】

变砖过程

先前刷的CoreELEC9.0.2版本，想升级9.0.3。这个时候9.0.3的优盘已做好，错误的插在了N1靠近HDMI的USB插口，ssh输入命令reboot update，然后去N1那里看，出错了！再重启就卡在开机画面不动了，感觉是砖了……

总结：降级、刷错包、刷机时断电，都可能变砖。救砖尝试

1、尝试：U盘启动，失败！！2、尝试：拆机短接，线刷W大的2.1和2.2，失败！！传送门：【V2.1】 | 【V2.2】3、尝试：加秘钥线刷V3救砖包，失败！！传送门：【V3】

拆机继续尝试，TTL救砖

参考N1不能通过网络刷机后拆机救砖如果只是不能进线刷模式，导致不能刷机，又不能通过网络进入刷机模式，可以通过用镊子短接2个点，强行进入刷机模式，刷机！！如果还刷不成功请继续看！

准备工具：电烙铁和焊锡公母、公公头杜邦线若干排针镊子螺丝刀等拆机工具

N1拆机焊接TTL.jpg 焊接RX/TX/GND，RX - TXTX - RXGND - GND用USB转串口，连接电脑，设置串口号（设备管理器中查看）和波特率115200盒子上电看到串口打印信息（恩山论坛玩家说，有回显说明没真砖，BootLoader还在）。进入Uboot命令行：uboot命令行的启动方式，板子启动后在PC端的putty界面中通过串口快速按任意键或者输入ctrl+c，即可进入uboot命令行模式。用户由p230# 变成了 gxl_p230_v1#在这个模式下，将N1降级恢复线刷的3个文件boot.img、bootloader.img、recovery.img三个文件拷到一个fat32格式的U盘中，（U盘必须是单分区的），一定要确定文件，没有问题，必须是v2.19版本的。将U盘插入N1盒子，putty中逐条输入如下三条命令更新系统boot：

usb_update bootloader bootloader.img usb_update recovery recovery.img usb_update boot boot.img

逐条执行命令后，串口返回的信息：

usb_update bootloader bootloader.img 执行返回：
