Custom ROMS Failing topic

Hi guys

I just got dual recovery installed on my Xperia Tablet Z SGP321 XZDualRecovery - TWRP/PhilZ
Specs - Android 4.2.2, Rooted with vroot

Tablet Ready For Custom ROMS? I don't think so...

I downloaded a few custom ROMS for my tablet
Placed it on my sdcard, booted into recovery, wiped and install and FAIL, with 4 Roms i've already tried, I'm out of options

People any ideas? Am I missing a step?
