ARRIS SBR AC1750 从折腾到救砖到放弃

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。

ARRIS SBR AC1750 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

触点在板上的位置

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)

联通点

看端口ID

screen 连接,我这里用 115200 可以正常查看,如果是乱码可以试试别的,如 57600、120000、128000

看到下面输出结果:

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。

  1. 用网线连接电脑和路由,网线插在路由上任意一个 Lan 口
  2. 设置电脑连接路由的网卡 IP 为 192.168.1.2 ,网关 255.255.255.0
  3. 按住 WPS 键不松手,开机后等 8 秒再松手WPS键
  4. 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
  5. 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

Bash:
1
2
3
4
5
% sudo launchctl load -F /System/Library/LaunchDaemons/tftp.plist
% sudo launchctl start com.apple.tftpd
% tftp 192.168.1.1
tftp> binary
tftp> put your_bin_file_path

这里收到的提示是 Transfer timed out.

宣告失败,正式丢进垃圾桶。

ARRIS SBR AC1750 路由变砖拆解折腾

五个月前在某宝上看关于 ARRIS SBR-AC1750 的介绍,挺酷的,买一台店家刷好的 PandoraBox 系统。最近才折腾,试刷其它的系统,最终变砖。...
