tp 740 v4 刷 dd变砖
我的740很是诡异，希望他继续诡异下去啊，原本是740 v4的，后来升级成741 v1 刷op刷好后又想刷dd，直接刷dd未果，死机进不去系统，想ttl呢结果第二天又可以进去了，进去是741v1，有刷op后刷dd成功，现在想还原成740v4，给我哥哥用，他不会这些，想刷官方稳定点吧，刷机时一时脑残选了740v4的安装包，恢复完成后发现成砖了，这次应该真诚砖了，插上电源就来回重启，现在应该怎么办啊？以上的dd op都是741的，急求啊有ttl线 loding。。。 发表于 2013-4-15 16:39 static/image/common/back.gifAbort

网卡ip设为100，tftp重新打开后，里面的ip要跟网卡一致。 上编程器吧，兄弟！ ttl 看看错误信息再说 这种情况uboot一般没坏的，上ttl刷回去吧。 jiafpe 发表于 2013-4-14 23:02 static/image/common/back.gif

连完完后就这样，一直在tttttt这个循环过不去 ttl 能进去 uboot应该还能用 试试ctrl + c或者t p i 三个键狂按，尝试上传固件修复，如果不行，就只能编程器修复了 loding。。。 发表于 2013-4-15 16:07 static/image/common/back.gif

检查一下tftp服务器地址有没有错？固件放在tftp文件夹里面，正常的话tftp会出现上传固件的界面的。 lookball 发表于 2013-4-15 16:16 static/image/common/back.gif

网卡ip设为100，tftp重新打开后，里面的ip要跟网卡一致。
