[Q] Flash Sensation Custom Roms Steps order!

[X_Blue]

Hey guys,

After reading a lot of guides to flash a custom Rom to sensation ... i just want to to know 2 things:

First: is Recovery is mandatory? if yes.. why?
Second: i want to flash roms like ViperS rom or CM10... the steps i understood so far is :
1-S-OFF using [GUIDE] Juopunutbear S-OFF NO HTCDEV UNLOCK | ROOT (1.2x HBOOTS)--NEW: ONE CLICK ROOT
2-Flash the custom rom ... but really i don't know the exact steps to do that ....

I just want ordered guides to read to help me flash the rom.

My Sensation:
HBOOT 1.27
Software 3.33.415.51
Android version: 4.03

Best Regards,
