As promised, homebrew team Noobz have rolled out a upgrader / downgrader for those who are still stuck on firmware 3.11 due to idstorage key checks.
[blockquote2]This release consists of HEN for v3.11, plus a v3.11 downgrader, and an idstorage key fixer for v3.11. This allows you the choice of either
1. staying on v3.11 to run homebrew
2. downgrading to v1.50 to run homebrew or install custom firmwares, or
3. upgrading to official Sony firmwares v3.30 or beyond.[/blockquote2]
