First thing's first, ONLY USE SXOS 1.2! 1.0 will burn your fuses, and 1.1 doesn't bypass the fuse checks.
Second, you'll need to boot into the firmware you're wanting to run with at least once using Hekate. After that load up briccmiiv2 and use vol+ (Only once!) to repair your cust_data so SXOS 1.2 will be able to run with it.
This will allow you to downgrade your firm back to 2.0.0 whenever you want, as the fuses won't get burned. It's risky though, so do it at your own risk.
Just follow the guide on that post.
