Default [Q] Recovery Mode Problem - Galaxy Young (6310n)

Hello all.

I'm sorry to bother you, but i've been stuck for 3 days, trying to work around my Samsung Young and the Root process.

I've tried all software that exists, without any success.
Used Odin to flash the CWM (which is the problem that i have), Framaroot, and many exploit sw.

The question is that i'm trying to root the phone. However, when using the recovery mode (CWM) and try to update it, using SD Card, it gives me the "E: unknown volume for path".

When tried to use Odin, in the download mode, i got the error on phone screen "signature verification failed".

So, is there any other option to update the Samsung, root it and install superuser?

I would like some help, please.

Thank you
