买的浙江的二手贝尔GPON光猫，结果在安徽无法注册，IMTS注册超时，看起来像是这个光猫无法写入IMTS数据导致的。因为里面lan地址和tr069信息都是灰的，无法修改，刚开始以为是没有完全恢复到出厂设置，于是telnet上去重命名了两个配置文件，结果导致电脑无法连接光猫，用牙签顶重置按钮恢复设置也没有用处，以为就此变砖了，后来拆机后发现有TTL接口，连上电脑后，把重命名的文件恢复过来，电脑又能连上光猫了，但是光猫注册问题还是不知道怎么解决，登陆光猫，也没发现有什么升级界面，固件也无法刷，TTL下忘了试一下了，各位大侠有什么好办法吗？: h# r% _! {4 G$ C% E. k7 H& B& [# s) p

彻底挂了，erase all后关电源重启了，没想到就此全被清除了，连U-Boot都被清除了，理应在erase all之后立即upgradeimg的，这样U-Boot才会再次被安装，才会重启后能有固件，现在flash全被清空了，启动不了，没有相应的编程器，基本上这个就是砖头了
