[Q] Help needed to install new roms

So last week, to save my near bricked device I used PC Odin to Flash a GB Rom. The device works fine now, with all root privileges. I ran titanium backup and installed all of my apps from the previous rom. But i can't seem to install a new rom using the recovery mode route. Whenever I try to install a new rom (GB, ICS OR JB) using recovery, I get boot loop or get stuck on the setup screen. Info on the rom I'm using right now -

Build Number- Gingerbread.XXKJ1
Baseband Version N7000XXLB2
Kernel Version- 2.6.35.7-N70000XXKJ1-CL627135se.infra@SEP-24#2
Android Version- 2.3.5

I want to install an JB AOSP rom. Please give me step by step instruction on how to do it.
