GeoHot PS3 Custom Themes Hack Demonstration Arrives


Sponsored Links
249w ago - Today GeoHot has posted a few pictures (below) with the title "Custom Themes?" on the latest PlayStation 3 blog entry, however, no other useful details are available of the PS3 hack demonstration.

To speculate, it appears to illustrate modifying the PS3 GameOS XMB memory areas, but this was already known over a month ago when word first spread of the PS3 Hypervisor lv2 being dumped and reversed.

It's an RCO file edit, just like RCO edits on the PSP (almost same format too). RCO files are resource files for VSH plugins, live in the dev_flash, and aren't signed. To edit them on your system, patch your hypervisor to allow encrypted access to the partition (flash on old systems, hd on new), and mod ps3pf_storage. dev_flash is just a FAT partition, mount it in Linux and change what you'd like.

Nevertheless, it looks like progress is indeed being made editing and replacing an RCO in /dev_flash/vsh/resource/, although it would be nice if the information was made public so that other PS3 Devs in the scene could join in the fun.

From NDT: Le foto sono vere al 100% Ha modificato gli RCO dal dump della ram ma dato che non sono signed questo significa proprio poco. Si vede che stava cercando anche lui qualcosa da postare.

Rough translation: The photos are real 100% Changed the RCO by dump ram but since they have not signed this means just a little. One can see that he was looking for something to post.

Mathieulh: It's real, it has nothing to do with custom backgrounds, what he did was replace a rco file in dev_flash with one he edited (with a custom text in it).

To do that he had to mount dev_flash as rw because it is normally read only. You can do that if you know how to using his exploit under otheros.

As always, more details to come as they are available!

Anyways, I'm just curious to know how far he can go on messing with the console. I mean, any chance of him being close to homebrew? Any guess?

its' not fake check the details of the picture

he used a Canon EOS DIGITAL REBEL XSi

Well, considering we knew he had lv2 dumped over a month ago I doubt it's fake... so that is basically a moot point to most Devs in the scene.

It's clear GeoHot is in it for the attention though, as his last few blog entries have been nothing but showboating versus contributing the useful details on how things are done for other Devs.

well... really cool news... hope we will see some stuff... and something really really big. Great news... and nice work GEOHOT!

Still can't understand do i need to use exploit or we can just download hacked theme and do this trick? or we need to modify GAMEOS?
