Hi All,

on K series the iframe still can access the local files with simple code :

Code: Select all

<iframe style="background: #FFFFFF;" src="file:///proc/meminfo" height=1000 width=700>></iframe>

can somebody maybe provide a filesystem layout or a files list please ?
ls -lR would be the best... but off course each file with full path would help too..
maybe from some firmware dump ?

Thank you very much.

Here you go:
T_JZMDEUC_1111_dumps.zip

Archive contains kernel dump (basically uImage) and rootfs dump (vdfs image) you have to use that to extract (x86 binary included, recompile if needed).

Enjoy :)

Do you mean you have such a software? Can you share it maybe ? or is it a question if such a software exists ?
as I know the msd file is RSA encrypted, and we need a key for it...

Hehe I think he is asking for such software but you wouldn't get anything from it. Dumps have same information do NOT require any keys you simply dd/cat partition and extract raw data :) If you want to get somewhere analyse dumps and find bugs :)

Yeah, samsung does :P And WHAT would that "key" give us ? :) It asymmetric cipher and allows you ONLY to DEcrypt updates and NOT ENcrypt :) (For reference check code for previous series).
