I followed every step in the readme correctly and have my 2G restored with the custom ipsw. Everything goes well, except I cannot get fsboot to do anything (./rslite results in ERROR). I get it to boot up, but Cydia.app does not appear on my springboard, even after trying to boot it in tethered mode. I cannot SSH into it, either. Not sure what went wrong. Somebody who actually got this working in mac, please tell me what I am doing wrong.
