中兴8820S与8820V2比较及TTL刷机
本帖最后由 rockg 于 2021-2-3 07:45 编辑一、8820S与8820V2
中兴8820S与8820V2方案一样7621+7612+7603，8820V2是64M的内存，8820S是256M，所以怎么说8820S都是V2的升级版。
两个外形一样，使用上面8820s(白色的）多了一个电源开关，使用上方便了不少，内部也多了金属散热片更有利于长期的稳定工作。目前两款2手都是50不到，感觉8820s性价比更高。
二、关于刷机
目前两款都可以刷，刷后5G，2G信号等一切正常。8820V2坛里介绍很多，8820S隔壁老鸟也已经搞定了，我也是新手。所以下面就8820S的刷机过程介绍一下。
关于8820V2的刷机可以参考：
1）电信天翼宽带-中兴 E8820V2 到手拆机(和新路由3-歌华链相似)及固件
https://www.right.com.cn/forum/thread-530906-1-1.html
2）中兴E8820V2在ttl下备份固件和刷breed方法
https://www.right.com.cn/forum/thread-3995499-1-1.html
关于8820S的刷机，我也是主要参考隔壁：
[无线] 拆咸鱼50包邮收的中兴8820s路由器，附刷机方法和信号巨好的EEPROM
https://www.mydigit.cn/forum.php?mod=viewthread&tid=156841
所以老鸟对下面的内容可以略过，对于小白特别是第一次捣鼓TTL刷机的则可以参考一下。
三、8820S的TTL刷机步骤：
1、拆机和连接TTL转USB模块
**** Hidden Message *****
2、刷机，
1）连接好TTL模块后（注意路由主板不要通电），将TTL模块与电脑USB连接，刷机软件可以用putty或secureCRT,推荐secureCRT，下面以secureCRT为例。
2）secureCRT新建串口连接，具体参数见下，流控什么的都不要选，否则会出现无法输入的情况。
然后点连接，会出现下来的串口编辑窗口
3）路由通电，会看到串口编辑窗口有数据传送，见下，恭喜你，基本上就成功了，如果什么都没有，检测驱动、USB模块、焊接等是不是有问题。
4）剩下来的就是就是耐心等待，路由完全启动好后，编辑窗口敲回车，出现登录界面：
5）用户名：zte_wrt； 密码：12345!@#$%。登入后将带刷的breed拷入U盘，然后将U盘插入路由的USB口上。
8820s用极路由B70breed：breed-mt7621-hiwifi-hc5962.bin
下载网址：https://breed.hackpascal.net/
6) 备份原系统及将breed刷入8820S
cd /mnt/usb1_1 #进入U盘
cat /proc/mtd #显示原系统
cat /dev/mtd0 > whole_s_22.bin #备份mtd0
ls #查看U盘文件
cat s.bin > /dev/mtdblock1 #将B70的breed刷入8820s,"s.bin"是改名的breed-mt7621-hiwifi-hc5962.bin
reboot #路由重启
路由重启后，在串口编辑窗口会看到重启信息，以及路由进入breed的状态，TTL刷机大功告成！！
3、breed web 控制台备份原厂固件刷入lemontreenm大改造的eeprom,以及各种各样的固件
B70breed完美支持8820s，内存识别等完美，刷固件也完美！！！
lemom大定制的eeprom:；对8820S支持也非常好，5G和2G信号非常稳定，刷入后记得修改成自己的MAC地址。
8820S Mac地址的规则是：LAN，WAN，RF1WLAN就是机器背面的地址，RF2的地址加1，具体见下：
4、关于8820S可以用固件：
所有支持支持极路由B70的固件8820S都能完美运行，固件集参考：
目前极路由4增强版（B70）可用的最新固件整理！Padavan_PandoraBox_灯大_hanwckf_H大
https://www.right.com.cn/forum/thread-4001524-1-1.html
推荐使用：hanwckf_B70_3.4.3.9-099_v4.2.1.0_20200401.trx，比较精简，信号也很好，固件里面一些常用拓展功能也有，USB打印什么的。
问题有两个：1）路由器电源、5G、2G信号灯不亮（可能有些人更喜欢这样），但是刷pandoraBox的固件所有指示灯都能完美点亮。
2）B70只有3个有线LAN口，所以所有固件都只能显示3个（2,3,4）的LAN口连接状态，但是不影响LAN1口的使用。见下：
2020-08-16 编译了8820S适用的padavan固件，解决了网口显示的问题，需要的可以下面下载：
