Cant find the noob guide :)

[smitty1258]

Just got my replacement xv6900 and am looking to put the new ROM from htc on it.

I would like to do whatever steps are involved to do this, however Ive read about 5-6 threads already, and they all have different little things about them, and I am not sure if they are specific to those roms, or what and now Im more confused than I was before.

So im basically looking for the noob guide.

Step 1, do this
Step 2, install run this
etc....

From what i gather, I need to first unlock my phone?
http://forum.ppcgeeks.com/showthread.php?t=20370 I would be 0.40(nonGPS) correct?

Then what? Install kitchen? another app? what? There has to be a question similar to mine around here, or another thread detailing, what i need to do. Any help is greatly apprenticed.

Thanks in Advance.
