Graf Chokolo Updates PS3DM to Enable Service Mode in PS3 Linux

[PS3 News]

Following up on his previous releases, today PlayStation 3 hacker Graf Chokolo has released a PS3DM utils update to enable Service Mode from PS3 Linux.

To quote: Guys, take a look at my ps3dm-utils. Now you can enable service mode from Linux. Look at ps3dm_usb_dongle_auth.

What service mode can do for us? Well, there's many but i think the most useful one is the downgrading function where you can downgrade the PS3 firmware to the older versions. From the look of it though, it still requires USB dongle to get the job done, correct me if I'm wrong since i didn't look further enough to verify this. Anyhow, can't wait for the release of the noob proof PS3 Linux, OtherOS++.

Update: Jess has confirmed that USB dongle is not necessary to get into the service mode. No you don´t need a dongle! You can invoke it from linux. All the modules comunicate throught dm proxy.

Now you can simulate a dongle through software and authenticate through linux. You can generate the challange and create the adequate response.

From http://grafchokolo.com/ps3-development-page.html/comment-page-8/#comment-2614 himself:

1st step - Generating a challenge

# ps3dm_usb_dongle_auth /dev/ps3dmproxy gen_challenge

2nd step - Generating a valid response for a challenge

You need a dongle id. Valid range for dongle IDs is 0×0000 - 0xffff. So choose one, doesn't matter which one, but some are revoked !!!

# ps3dm_usb_dongle_auth /dev/ps3dmproxy gen_resp 0xBABE

3rd step - Verifying response (Enabling "Product Mode")

# ps3dm_usb_dongle_auth /dev/ps3dmproxy verify_resp 0xBABE

4th step - Checking if "Product Mode" is enabled

The returned value shouldn't be 0xff.

# ps3dm_um /dev/ps3dmproxy read_eprom 0x48C07

5th step - Disabling "Product Mode"

# ps3dm_um /dev/ps3dmproxy write_eprom 0x48C07 0xff

this is great, especially for those of us "myself included" that love the power and feel of linux on the ps3, graf is one of the greatest hackers of our time.

That's fantastic news, now how the heck do I use this? tutorial anyone? I've got debian running, but don't know how to install these tools.

Please help, my ps3 has been broken for a year now, and I just need to downgrade so I can marry the working controller board to it...

These tools will not help you achieve your goal, you must look else where on the site in order to achieve your goal and will need a dongle.

Ok, so then i'm pretty confused. why was this "Update: Jess has confirmed that USB dongle is not necessary to get into the service mode. No you don´t need a dongle! You can invoke it from linux. All the modules comunicate throught dm proxy." in the OP if you still need a dongle?
