Hello, i try to install E2 1.0.21 i think, but when i try to use it, only show "geeko :P"

If i put the pen in that show-me the ip address and i can login in into telnet...
i know to recover it i should use AZUP, but i dont have computers with M$ WINDOW$, so i just use ubuntu in my house, and wine cannt use sucessfull AZUP, can anyone post the manual to recover azbox to original FW with out AZUP ?
thanks
