WR720N救砖，无法TPL中断，搞了一天都搞不好，求助

我的WR720N刷openwrt，由于没有成功拨号，自己改了设置，结果就出问题了，插上网线，电源，开机等亮，开始是一闪一闪的，然后常亮，和原来正常是用的一样。但是本地连接就有问题了，总是“正在连接”--“连接成功”--“断开连接”--“正在连接”--“连接成功”--“断开连接”-------不断循环，电脑运行里CMD，输入ping 192.168.1.1-t，不通，无法telnet 192.168.1.1，于是找朋友帮我接线，按照论坛上的接线方式焊的。如图

线接好了，然后我接到TTL转USB，我的TTL转USB是“CP2102”，不知道是不是我的TTL转USB不适合用了。我见网上很多都是PL2303的。
板子不接电源，网线，电脑安装好好驱动，把接上的USB转TTL插入电脑，在“设备管理”中设置COM1的端口参数“115200” “8” “无” “1” “无”。打开“单片机多功能调试助手”，设置串口参数“COM1” &115200& &8& &1& &NONE&&&，发送和接受数据正常。关掉“单片机多功能调试助手”，打开“SecureCRT”，点击“快速链接”，协议 “serial”&&端口&COM1&&&波特率“115200”&&数据位“8”&&奇偶校验“NONE”&&停止位“1” ，如图

接上路由器电源，链接出现内容了，估计链接成功了吧，但是我怎么也中断不了UBOOT，整个过程中多次输入&tpl&然后“回车” 均无中断。以为没接网线，就接上网线试，wan口插过，lan口也插过，还是中断不了。设置过“映射键”，输入过“t”&&&tp&&&&0&&&&1&&&&ctrl+c& 等等。结果都出现同样的内容，UBOOT都没有中断。我现在的情况怎么处理啊？
是我哪一个步骤出问题？？我该怎么办才能修好我的路由器呢？？？？？

哈哈& & 重刷固件
上编程器吧
怎样重刷固件呢？能教我吗？没有编程器，也不会用编程器啊
按TPL一定要快，多试试，很多坑爹uboot的中断需要飞快的按
另，免费修砖，带材料免费换flash、ram，纯爱好
江浙沪的话可以帮你用编程器刷下
接收信号正常，不知道发送正不正常。楼主的是Openwrt吧，原厂UBOOT的话，按小写的tpl，通电就按，多试几次。速度要快。
顶啊！！！！！！！！！！
根本你就无需上ttl, 720n刚通电时，连续狂按reset孔， 很快你会看到led灯快速地闪，然后你用网线连接上去，telnet 192.168.1.1， 可以进入安全模式，输入firstboot，回车，重启，那么你的openwrt就会重置设置，你这个根本不是砖，也不是硬件故障。
试过了，快速闪的后，telnet输入没反应，
多谢楼上，按你的方法已成功搞好了

楼主啊，按照你说的方法改到3g模式了，还是不行啊，都ping不通。。还是一样没法...
有没有关掉720的DHCP服务，3G模式那个服务是默认开启的

您好！IP改成自动分配。在哪该啊！
这个也要教？

信号还行，速度也比较稳定，用的拨号上网，没试过别的功能，只是那个电源功能吗，说的是2A电流，还没我那600毫安的充电器充电快，虚标严重
