Tôi đang dùng con Router 3660 của Cisco. Tôi đã cố gắng nâng cấp IOS (sơ suất quên backup lại), sau khi khởi động lại đều bị lỗi. Tôi đã cố gắng nạp lại khá nhiều lần nhiều bản IOS khác nhau (bằng phương pháp Xmodem) nhưng đều bị lỗi trong quá trình khởi động (không load được IOS).

Trước khi nâng cấp IOS:

Router#show version
Code:
Cisco Internetwork Operating System Software

Sau khi nạp IOS thì xuất hiện lỗi sau trong quá trình khởi động:
Code:

Tôi đang khá bế tắc và chưa tìm ra cách giải quyết. Mong mọi người giúp đỡ.
