PS3 Developer JaicraB on Special Execution Mode WIP

800°
188w ago - Today Spanish PS3 developer JaicraB has posted an update on his blog (linked above) of what appears to be a PS3 special execution mode WIP.

With it, he may be able to get the PS3 into service mode (possibly for downgrading and other delightful things) so let us hail him and hope there is more to come for us all.

For those who missed it, a few months back RichDevX also noted some progress in this area using a PSGroove Payload for PS3 Service Mode.

Some pictures are posted below, and to quote roughly translated:

"Look at this...., It seems not only egocentrics know how to do things and then sell their products.

A gift for DemonHades, Happy birthday to you !"





 

PS3 Firmware 3.50 Decrypted, Free Public PS3 Downgrader WIP

1100°
191w ago - Just a few days back we saw a video of PS Downgrade software by the PSJailBreak Team in action, and today graf_chokolo has posted on xorloser's blog (linked above) that he has decrypted PS3 Firmware 3.50 and while it's still a WIP it could very well lead to a free public PlayStation 3 downgrader alternative.

To quote: I am able now to decrypt and decompress CORE_OS_PACKAGE.pkg from PS3 PUP-Files. The decrypted and decompressed package is a copy of FLASH region where all the important SELFs and isolated SPUs stored, e.g. lv1.self or isoldr.

So, now i could downgrade PS3 by writing this decrypted image to FLASH manually, without Update Manager from HV. In fact, Update Manager just do this But the problem is, that the SHA-1 hash values for these files are stored not in flash but in SC EEPROM and i don't have access to it yet

Here is a snippet from CORE_OS_PACKAGE.pkg 3.15:

PS3 TEST Backup Launcher V.001 Alpha WIP

800°
331w ago - While we await the start of our PS3 KeyVault Project for retail PS3 consoles, below is a screenshot of something else I have been tinkering with recently via Debug.

As hinted by PS3News already HERE, it is a Backup Launcher for a PS3 Development Unit as shown. At the moment it it still pre-Alpha and very incomplete, however it allows:

- Boot PS3 Games from HDD
- Boot PS3 Games from DVD/BD-ROM
- Copy Original PS3 Games from DVD/BD-ROM to HDD
- Patch the executable on some games to run from HDD

Note: This will ONLY work on a DEVELOPMENT CONSOLE, not a RETAIL PS3 unit!

To be added soon:

- Read PARAM.SFO for name/titleid, patch to menu (Alpha is hard-coded)
- Support for deleting games from the menu
- Support a few more games to start (Alpha is hard-coded for four)
- Possible support for a "select" menu, versus the button presses

Optimistic things to be added:

- A better GUI
- Backing up PS3 Game files to PC

For those curious, how it works briefly: when the launcher is started, you can copy a game to the PS3 HDD. It will create a folder on the hard disk and copy the Game...
