GL-MT3000更改为国际版

备份分区，先用fdisk列出分区结构，找不到fdisk命令的话先安装fdisk软件包 fdisk -l

Disk /dev/mtdblock0: 256 MiB, 268435456 bytes, 524288 sectors

讲分区备份到u盘

dd if=/dev/mtdblock0 of=/tmp/mountd/disk1_part1/mtdblock0.bak
dd if=/dev/mtdblock1 of=/tmp/mountd/disk1_part1/mtdblock1.bak
dd if=/dev/mtdblock2 of=/tmp/mountd/disk1_part1/mtdblock2.bak
dd if=/dev/mtdblock3 of=/tmp/mountd/disk1_part1/mtdblock3.bak
dd if=/dev/mtdblock4 of=/tmp/mountd/disk1_part1/mtdblock4.bak
dd if=/dev/mtdblock5 of=/tmp/mountd/disk1_part1/mtdblock5.bak
dd if=/dev/mtdblock6 of=/tmp/mountd/disk1_part1/mtdblock6.bak
dd if=/dev/ubiblock0_1 of=/tmp/mountd/disk1_part1/ubiblock0_1.bak

然后运行以下3命令

echo "US" |dd of=/dev/mtdblock3 bs=1 seek=136
sync
reboot

重启后，把语言改成英文或者繁体英文，既可看到ad guardhome菜单
