There is a complete solution for your system once that you can do before the laser completely dies.
First thing I suggest is to install Free MC Boot. This is the only exploit that will work without any trigger disc. this way you will have a 'Dev mode' that you can use to boot homebrew from your MC such as LaunchELF.
You also need to patch your codebreaker 9.3 with a specific patch from ffgriever that will allow you to boot HDA directly from codebreaker instead of a disc. there are few known versions of 9.3 that can be patched and they have to have specific MD5 checksums. The non-Gamestop version can be ripped from your retail disc and patched.
Once this is done, it would be easier to launch Codebreaker from your USB stick from the OSDSYS menu (outer sony broswser with menu) via FMCB. Your HDA would be renamed CB_launch.elf and placed in hdd0:/__boot/ as that is the first place the patched codebreaker will look for it in.
but once that stuff is taken care of, your laser can crap out and you'll never miss it until you come across a game that isn't compatible with HDA.
