1.5-1.0 Downgrader

**Shrygue** · October 13th, 2006, 17:39

There is the DEVHOOK Launcher/VSHEX Mod
Version 1.61 and that has an firmware version 1.00 EBOOT.PBP but when I select a dump to load (like 2.50 or 2.71) amd attempt to start it, the PSP crashes and so it won't work. It's a shame, because I have a version 1.00 PSP (a european 1004 series unit if anyone wants to know) downgraded from 1.50 so I can run unsiged code quickly, rather than via IRshell 2.20

That was pretty confusing to read, but thanks for pointing out about that new "Devhook Launcher/VSHEX Mod" thing...
I didn't know that existed before, but from what I can tell it does not work on fw 1.00, just like nearly every other loader like it.

So therefore it isn't really very useful to either of us.

I've always had fw 1.00... HookBoot and DevHook (up to version 0.22) are the only loaders that work as far as I know...
The only other way to sometimes get non-1.00 UMDs to work is using SXT or WAB firmware version number fakers...
I use SXT to get Tony Hawks Underground 2 working as DH 0.22 won't load it.

If you can't find anyone with version 1.00 to obtain their firmware dump for the downgrade then yes you are screwed. Of course, you can use Google to find a full version (the downgrader complete with the 1.00 firmware dump).
