Question stock rom to rocket rom v9-kl3

hi, im new to in android. currently I rooted my phone with zergrush+CWM v3.0 installed. my question is, should i install [ROM] 2.3.6 Deodexed STOCK XXKL3/Modem DDKL1 - MultiCSC - Rooted (CF-Root-KL3, CWM5) before flash to Rocket Rom v9-KL3? I tried several tricks like FULL wipe before install the zip file in CWM recovery & also did FULL wipe after install the rom. but I still getting a bootloop.
