k2p刷pandorabox

发布时间：March 21, 2018 // 分类：K2P // No Comments

买了一台别人零元购的k2p a1版（现在新版都是b1），可以刷openwrt类系统，自带系统版本V22.5.7.85。
先开启telnet，访问 http://iytc.net/k2p.php根据mac生成配置文件并在路由管理界面恢复配置文件，重新启动telnet就开启了，默认密码为空。
查看当前mtd表信息：

cat /proc/mtd
dev:    size   erasesize  name
mtd0: 01000000 00010000 "ALL"
mtd1: 00030000 00010000 "Bootloader"
mtd2: 00010000 00010000 "Config"
mtd3: 00010000 00010000 "Factory"
mtd4: 00050000 00010000 "permanent_config"
mtd5: 00f60000 00010000 "firmware"
mtd6: 00c48b96 00010000 "rootfs"
mtd7: 00200000 00010000 "rootfs_data"

备份系统固件，并通过路由web下载，详见 http://www.right.com.cn/forum/thread-217088-1-1.html

#备份所有
dd if=/dev/mtd0 of=/tmp/all.bin
cd /www
touch all.bin
mount --bind /tmp/all.bin /www/all.bin
#仅备份固件，后续如果恢复官方固件可以在breed界面刷入此固件。
dd if=/dev/mtd5 of=/tmp/fs.bin
cd /www
touch fs.bin
mount --bind /tmp/fs.bin /www/fs.bin
#备份eeprom
dd if=/dev/mtd3 of=/tmp/eeprom.bin
cd /www
touch eeprom.bin
mount --bind /tmp/eeprom.bin /www/eeprom.bin

使用breed刷入别的固件并引导系统，下载breed到http服务器上，自带的wget不支持https，然后在路由器上wget下载到/tmp/目录，

wget -P /tmp/ https://www.haiyun.me/breed-mt7621-phicomm-k2p.bin
mtd -r write /tmp/breed-mt7621-phicomm-k2p.bin Bootloader
Unlocking Bootloader ...

Writing from /tmp/breed-mt7621-phicomm-k2p.bin to Bootloader ...

断电按住重置按钮通电，直到电脑网卡获取到IP，访问192.168.1.1刷入PandoraBox固件

一些初始化设置，iptables：

cat <<EOF > /etc/init.d/iptables
#!/bin/sh /etc/rc.common
START=19

start() {
  iptables -F
  iptables -X
  iptables -Z
