    Question [FAQ] Total_Noob's HEN

    The following is a list of commonly asked questions regarding Total_Noob's HEN for firmware versions 6.20, 6.30, 6.31, 6.35, and any other firmware he may develop this for. Hopefully this will help clear up any questions people may have.


    What is a HEN?
    A HEN is a Homebrew Enabler. This means you can launch homebrew directly from the XMB without using a Loader (such has HBL). It is not a CFW so it usually can't launch ISOs unless there is an ISO Loader homebrew.

    Where can I download it?
    I will list several links so if one link doesn't work, the other will. You may find it on PSP-Hacks, Wololo.net, PSP Gen, PSP Hack Guides, Endless Paradigm, or PSPSlimHacks.

    It doesn't work on my PSP-3000! HELP!
    You will need to use the unofficial patch made by Chinese developer 忠贞炙烈之炎 (virtuous flame). Get it here.

    Will it be released for 6.30, 6.31, or 6.35?
    Yes, eventually. We do not have a release date for these firmwares. We aren't psychic and can't see the future.

    Should I upgrade from 5.03 GEN-C to use this?
    There is no ISO loader for the HEN yet. Personally, I would wait until it had support for custom themes and plugins.

    Should I upgrade from 5.00 M33 or 5.50 GEN to use this?
    Why would you want to? This is made for people with the unhackable PSPs. Unless a permanent custom firmware is created for 6.20, I would NOT upgrade.

    I already upgraded, is it possible to downgrade back to 5.03??
    Total_Noob said he was going to make a "downgrade homebrew" but I do not know if that is only for the hackable PSPs or if all PSPs can do it. You can use this HEN to launch a homebrew such as PSP Tool or OSPBT to create a Pandora battery if your PSP is able. You can use that to downgrade your PSP. Do not attempt any downgrade unless you know what you are doing 100%.

    Will this let me play ISO, CSO, or PSX games?
    Total_Noob will not be adding an ISO loader to this but there are several teams already working on an ISO Loader which will probably be available soon after the HEN is released. As for PSX games... that depends on if the popsloader plugin works on HEN, I guess.

    The following FAQs have been answered by Wololo on his website.
    If that doesn’t run isos, what’s the difference between TN Hen and a homebrew loader such as Half Byte Loader?

For example homebrews that require kernel access will most likely work with the HEN. This also means that the Hen opens the door to iso loading, plugins support, etc… through a LCFW (Live/Light Custom FirmWare)
    So, what’s the difference between a Hen and a CFW?
    Quote Originally Posted by wololo

    Well, ok, so what are the differences between a Hen, a CFW, and a LCFW?
    Quote Originally Posted by wololo
    I’ll try to make this short:
    • A CFW (custom firmware) is a bunch of hacks that enable iso loading, plugin support, recovery menu, etc… on old models of PSPs. The most famous work on CFW was performed by Dark_Alex. a CFW gets installed in the flash of the PSP, and overrides the Official firmware at startup. Technically, for the end user, it means that if you turn off your psp, then turn it on again, you still have the CFW. Custom Firmwares are not possible anymore on modern PSPs, as Sony patched a critical hardware bug that made CFW possible. The first motherboards to have this patch are the infamous “ta88v3″ released in summer 2008. Basically no PSP bought new after this period can get a CFW.
    • A LCFW (Live/Light Custom firmware) is the same thing as a CFW (actually, the LCFW we currently know about are mostly made of reverse engineered files from earlier CFWs), except it patches the Ram after the PSP is turned on (LCFW are usually kernel mode homebrews, so they require a kernel hack, which is what the Hen provides, see below). While the CFW patches the PSP firmware at boot time, for LCFW you need to patch the Ram after the Firmware is booted. From the end user’s point of view, this means that if you turn your PSP off, you will need to run the LCFW again (and, of course, the Hen before that) in order to activate it. Keep in mind that putting your PSP in “sleep” mode is not equivalent to turning it off. If you put your psp in sleep mode, the LCFW stays in Ram
    • A Hen, as we said earlier, is a kernel exploit + a few patches that allows to run unsigned software, including ones that have access to kernel. It is a necessary tool to install and run a LCFW.

    So Summary: CFW can not exist anymore in the current state of our knowledge, and is replaced by Hen+LCFW, which are a combination of a kernel exploit and some patches in the Ram to allow a “CFW-like” experience.
    No one wants a HEN! Make a custom firmware already!
    Make one yourself. You'll find that it's a lot harder than you think, so don't demand this.

    How does this exploit work? I want the technical details. Show me some source code!
    Davee has explained this particular kernel exploit on his blog. Read it here.


    If you have anymore questions about this, ask here and I will add them to the FAQ.

    Great definitions. Even 'I' learned something from that!. Thanks. The coining of LCFW is a good idea as it makes it a little less hazy of what HEN and HBL differences are. I doubt it will stick, but it should!
