四年前买的ARRIS SBR AC1750,折腾坏了一直丢在角落里,这两天花点时间再折腾一下,尝试 TTL 连接。先看最终 TTL 连线。
因为点太小,只能从电线里抽出细铜丝来焊接。
这款路由的前面经历《ARRIS SBR AC1750 路由变砖拆解折腾》
看看 TXD、RXD、GND、VCC 在板上的位置
很难直接在触点上焊接,本来想绕开焊接,用几根针对准触点,用夹子夹紧,因为不好固定,还是焊接吧!
用万用表找到附近联通的点,主要是 RXD、TXD 两点,GND 是地线,可以焊接到靠它最近的大金属盖上(确认与 TP9 联通)
看端口ID

哈哈,确实刷错了,果断放弃。
后来联系官方客服,客服提供一个 TFTP 修复方案,试了一下没成功。
- 用网线连接电脑和路由,网线插在路由上任意一个 Lan 口
- 设置电脑连接路由的网卡 IP 为
192.168.1.2
,网关255.255.255.0
- 按住 WPS 键不松手,开机后等 8 秒再松手WPS键
- 使用 TFTP 工具上传一个
.bin
文件,如 PandoraBox-ar71xx-generic-sbr-ac1750-2019-05-02-git-0f9088e63-squashfs-factory-kfs.bin - 如果固件上传成功,则再等 10 分钟重启下路由器即可
MAC 下使用 TFTP 刷机

这里收到的提示是 Transfer timed out.
宣告失败,正式丢进垃圾桶。
