Same here. P6210 doesn't boot. Tried fix root and not fix root when asked. Tried reinstalling ROM a second time without clearing data, cache, dalvik etc. as suggested by OP. No difference just stuck on "Galaxy Tab Plus" screen.
You have to install stock ICS, and then install this rom. Great ROM. My battery last longer than with stock or Paranoid Android.
But the stock interface is very ugly =\
