G7615使用telnet命令备份与刷写固件的方法,已在自己的电信版G7615实测成功.
分区备份命令,根据实际情况更改USB2_disc1 nand kread /dev/mtd1 0x0 0x300000 /mnt/USB2_disc1/mtd1.bin //备份mtd1到u盘mtd1.bin nand kread /dev/mtd2 0x0 0x200000 /mnt/USB2_disc1/mtd2.bin //备份mtd1到u盘mtd1.bin nand kread /dev/mtd3 0x0 0x400000 /mnt/USB2_disc1/mtd3.bin //备份mtd1到u盘mtd1.bin nand kread /dev/mtd4 0x0 0x400000 /mnt/USB2_disc1/mtd4.bin //备份mtd1到u盘mtd1.bin nand kread /dev/mtd5 0x0 0x800000 /mnt/USB2_disc1/mtd5.bin //备份mtd1到u盘mtd1.bin nand kread /dev/mtd7 0x0 0x1000000 /mnt/USB2_disc1/mtd7.bin //备份mtd1到u盘mtd1.bin nand kread /dev/mtd10 0x0 0x3000000 /mnt/USB2_disc1/mtd10.bin //备份mtd1到u盘mtd1.bin nand kread /dev/mtd12 0x0 0x2ac0000 /mnt/USB2_disc1/mtd12.bin //备份mtd1到u盘mtd1.bin nand kread /dev/mtd13 0x0 0x2800000 /mnt/USB2_disc1/mtd13.bin //备份mtd1到u盘mtd1.bin
upgradetest switchver 0 //切换版本0或1 fw_flashing //查看当前主备分区调用情况 cat /proc/mtd //查看全部分区 cat /proc/csp/versionstates //查看分区激活及校验信息
fw_flashing //查看当前调用分区情况，0在mtd9分区,1在mtd10分区 cd /mnt/USB2_disc1 //进入u盘目录,根据实际情况更改USB2_disc1 echo 2 > /proc/zteinfo/factory/factorymode //写入数字2到factorymode touch /userconfig/nanddebug //创建nanddubug临时目录 nand kerase /dev/mtd7 0x0 0x1000000 //擦除mtd7 nand kwrite /dev/mtd7 0x0 0x1000000 ./mtd7.bin //写入mtd7 nand kerase /dev/mtd10 0x0 0x3000000 //擦除mtd10 nand kwrite /dev/mtd10 0x0 0x3000000 ./mtd10.bin //写入mtd10 nand kerase /dev/mtd8 0x0 0x200000 //擦除mtd8 dbus分区 nand kerase /dev/mtd11 0x0 0x6800000 //擦除mtd11 plugin_data分区 rm /userconfig/nanddebug //删除nanddebug临时目录 reboot //重启光猫
如果使用fw_flashing查看到正在使用的分区,0就代表正在使用mtd6/mtd9,所要写入和擦除的就必须为mtd7/mtd10,在完成擦写备份分区后使用upgradetest switchver 1 切换主备分区,然后再刷写mtd6/mtd9.
