Downgraded PS3 on Kmeaw 3.55, want to upgrade to Rogero 4.30 2.05

Hi guys.

I got my PS3 back after being sent off to be downgraded from 4.31 OFW. I'm looking to put on Rogero 4.30 v 2.05.

I have read that installing CFW on a downgraded system can be dangerous as there's a chance of bricking.

Apart from running toggle_qa.pkg and making sure I can see the Edy Viewer, and then installing Rogero from the recovery menu, is there anything else I should be aware/arfaid of first?


Thanks a million, I'd really appreciate any help.
