【求助】Hg522（C版）升级固件失败，不断重启，求救！

jsun

小弟的Hg522是广东电信的，原始版本是V100R001C02B029SP02_GDCT。因为发现yes东发的“HG522V100R001C02B033_JSCT（C版）”固件预开双SSID，所以就想升级。但是本人新手什么都不懂，不知道bin文件是不能直接在路由器web界面升级的，我试了几次，都是提示文件不对。然后我又找了下其他版本的y文件和bin文件，都用了个华为升级软件去尝试升级（具体什么名字忘了），结果现在上电后不断复位重启，ping不通moden ip，虽然还能进入web升级界面，但不管用什么格式的固件升级到最后都是“无法打开”页面。现在好不容易找到一条TTL线，把启动信息读出来了。请大家帮我看看如何挽救，小弟不胜感激！

楼主，请教一下。华为HG522-C的TTL引脚哪个是VCC,RXD,TXD,GND
