Infectus Downgrade to 3.15
Infectus Downgrade to 3.15 –
OzModChips is offering a firmware downgrade from 3.50 to 3.15, to enable OtherOS again. Looks like developers were able to use the infectus chip to downgrade. They also talk a little bit about custom software, or custom firmware it looks like. The page is full of grammar errors, but you'll get the point.
3.15 Firmware Downgrade - Linux Reviver! FAT Consoles - $94.99 : OzModChips.com, Australian Supplier of WiiKey, Drivekey, M3, R4DS and CycloDS
"Currently only for FAT consoles! Slim console should be coming soon, fingers crossed!
With the help (well they did almost everything) of a developer, we are finally able to offer a service which allows us to restore firmware 3.15 on a Fat console. This firmware version will bring the ability to install Linux back to the console!
It is no secret that the PS3 is popular console and its current advertising tagline is that the console "Only Does everything". Unfortunately it came under fire this year when they start removing advertised features. The biggest uproar was over the removal of the option to install linux on 3.21 firmware and above. It has caused Sony to be caught up in a bunch of legal battles worldwide. 1 of them was in Australia. The Australian argued in court that it was unfair to remove an advertised feature with a firmware upgrade. There is always the option of not upgrading, but many people did not think the option would just dissapear! When you agree to Sony's terms and conditions, which would take you about 5 hours of non stop reading, they pretty much can do anything to your console. Unfortunately, regardless of what is fair and what is not fair between normal people, when it goes to court its just a bunch of words, and who can argue the best to the judge! Politics aside......
The whole downgrade this was done a while ago by Team Infectus, and we have figured out how to do it on newer consoles. It will involved us opening your console, soldering a million wires, extracting your NAND, patching it, and flashing a new NAND on. It doesn't matter what firmare you are on currently (we test on a 3.5 console) we can bring it back on 3.15
So far we have tested a couple of consoles, and it is working well. 1 thing to make sure you know...We only really extract the KEYs from your NAND. So everything else will be wiped clean, as the donar NAND we flash on is just a normal factory settings NAND.
Please make sure you backup all of your important content. Profiles, save games, etc!!! Everything, and I mean everything will dissapear.
Not sure what happened if you do a full backup and restore. we would guess that it wouldn't work, because the firmware is lower on the restore, not higher!
Geohot also proved that its possible to have custom updates. Before he left the PS3 scene he said he was working on getting linux on 3.15 for Slim consoles. We hope the developer who is working us will be able to do the same thing, but no luck yet.
From 3.15, you can go to any firmware you want. Here is a page to download Previous Sony updates to upgrade manually. Since 3.15 is the last firmware before all of this mess started, we will just put it to there
* 3.15 firmware is the last firmware that Linux can be installed on
* 3.21 blocks Linux and doesn't really bring anything new.
* 3.3 and 3.4 are just small updates, nothing major
* 3.41 is the most famous firmware I guess, the one that got us into trouble and made us all sad pandas with no money.
* 3.42 is like 3.41, but they removed some feature
* 3.50 add 3D for movies etc, but stops you from being able to use a lot fo 3rd party USb devices, like controllers etc.
You are correct. I added a extra letter to the link. Should work now. Sorry about that.

If ya read the post from OZModChips you'll get a good idea of there downgrading system, but you will have to modify your console for this method. Twists and wires through a ps3 to install the infectus. If I'm reading correctly, that would give us the ability to easily swap between all firmware versions between 3.5 and 3.15.
It's interesting to say the least. Anyone have some more technological knowledge feel free to express your theories on what something this could do. It'd then be a case of whether we want to open my ps3 for various mods, or keep the current dongles that don't require us opening anything
