Modding retail Xbox 360 for debug

[kanaka]

Hey guys, my current Xbox 360 I used for betas is dying, and I will need to replace it soon. The chance of me getting a devkit is null and I need some help modding a new retail one (the one I had was obtained from another user a long time ago). I know I will probably need a RGH mod and a change of BIOS, but I wanted to verify with you what should I get ready to do this (I will do this with the assistance of somebody else that is better skilled than me on these things).

Do you guys have any guides at hand that you recommend? Thanks in advance.
