有没有人遇到过lc5730无法刷rom的情况？

idalin

去年在本坛龙星那里买的lc5730，用倒是能用，但就是不稳定，在linux下也不怎么能用，能拔号成功，就是上不了网。于是想刷rom试试看看能不能改善，结果从32位的XP到 64位的win7都不行。现在rom版本还是1.00……
下面是刷最新的1.02的日志：

我用64位的WIN7也刷不了。。不想换系统，放弃鸟

idalin

刚才修改了download.cfg之后，居然刷成功了，而且linux下也能上网了，真是爽啊，总算把我的无限卡给用上了。

rocawear

楼主怎样修改了download.cfg  啊？？？分享一下可以吗？

idalin

把download.cfg中的
H_AT_VCOM_NAME = 0xLeadCore CMCC AT Interface
改成
H_AT_VCOM_NAME = 0xLeadCore CMCC Diagnoses

就刷成功了。

谢谢楼主分享~~晚点试一下~
