Today SKFU has updated his blog (linked above) with a follow-up to his previous work and shared some new information and progress regarding PS3 custom firmware.
He was able to add several more working debug options to JailBroken retail PS3 consoles, such as Title Store preview in the network section.
To quote: "While the USB Loader by JaicraB has some trouble rebooting all correctly it seems for a final CFW we need to overwrite dev_flash instead just loading live from USB mass storage.
Some things you can already do for a nice working CFW:
1. Replace all in "/vsh/module + /sys/external + /sys/internal" with the content of a 3.41 debug dev_flash.
2. In "/vsh/resource/explore/xmb/category_game.xml" add this in the "view id=root" Items section

This will bring the "/app_home/GAME" and "Install PKG" options back.
3. In "/vsh/resource/explore/xmb/category_psn.xml" switch "root" and "tool_root".
This will add Title Store previews in the network section.
4. In "/sys/external" you grab liblv2dbg_for_dex from a debug unit and rename it liblv2dbg_for_cex. Replace liblv2dbg_for_cex with your new one and also add the debug liblv2dbg_for_dex.
Now you also have the debug options enabled. I don't know how to show up the debug options icon yet, but you can modify the settings via the registry.
How2 Handle Debug Options Without Icon
All information should be free. So here another part of the Custom Firmware research.
My previous post already explained some changes they enable. One nice one I didn't mention yet is, that it activates the Debug Options.
The options are enabled now, just the icon is missing. But there is a different way you can handle them. As we already knew, the xregistry.sys (dev_flash2/etc) stores all actual settings.
With the changes mentioned in last post, if you tried those; you may have noticed a debug message in the upper right corner. This actually proves the debug options are unlocked to use.
Just extract the xregistry.sys now and find the debug options. Activate them with a 1 instead a 0. I didn't test all so far, but seems most is fine.
