i can't extract file gui_res.tar.lzma on fw hikvision
Can anyone help me?

The file is encrypted - it needs to be decrypted before it can be opened.
The encryption key is firmware-series specific.

How did you decrypt the file?
Attach a zipped copy and I will check it for you.

should be able to decrypt this for you tonight.

Attached are all the decrypted cramfs files, except uImage which is in plaintext as it is the Linux kernel.

[QUOTE = "alastairstevenson, post: 296001, thành viên: 1907"] Đính kèm là tất cả các tệp cramfs đã được giải mã, ngoại trừ uImage vốn có trong bản rõ vì nó là hạt nhân Linux. [/ QUOTE]
thank you
