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
