Ah, DevHook. Just the sheer mention of it sends shivers down the spine. So, you can just imagine our joy (and we're enjoying yours now) when homebrew coder Sleepy566 dropped by QJ Forums and informed us about an updated version of Tommydanger-original DevHook Firmware Installer.

In the last version, v0.6d, Sleepy566 mentioned that the application could install 3.11. However, the coder noticed that there were a couple of few missing code lines that allow full support for 3.11. Sleepy fixed that already and this program should run on all firmwares now.

Remember that you need to have the latest version DevHook installed to run this installer. Once you have that, extract everything in the ZIP file to the root of your memory stick. The changelog for Devhook Firmware Installer v0.6f is as follows:

Version 0.6f: Added full support for 3.11 (Didn't realize it was missing) and Minor bug fixes
Version 0.6e: Bug fixes, sometimes "couldn't generate OUT file"
