河南移动版DT720-CS怎么刷机改地区？

manincharge

手欠淘了一个河南移动版的DT720-CS,因telnet该地区重启后认证信息还是password没有变成loid以及rms还是河南的，说明没起作用。另外hidden_version_switch.html（或gch）打不开，网上讲封堵了，这个不知道能不能通过telnet启用呢？现在想问下怎么从同固件同版本的其他可以改地区的DT720cs机器上将固件提取出来刷进这个机器。提取固件我按这个“cat /dev/mtd1 > /mnt/USB1_disc1/uboot.bin”提取到了U盘上。就是怎么刷进机器里面呢。不懂刷机，有教程的麻烦私发个，能用后采纳
