125w ago - While we know that PS3 Firmware 3.55 patches the ability to downgrade your PlayStation 3 console, this weekend Dukio reports that brand new 3.50 PS3 Consoles may also not be downgradable as well.
To quote: "Amid reports of new PS3 Slims owners who have no luck in downgrading their PS3 consoles, i would like to warn those people who like to buy a new PS3 console and Jailbreak it by looking at these suggestions below:
1. Beware of pre-installed 3.50 firmwares PS3 Slims, most people have no success in downgrading their console with any methods online on these consoles. The new batch of PS3 slims might have been given some kind of protection in order to prevent it from downgrading to an earlier version of firmware. So, please take note of it.
2. If you still want to buy a stocked 3.50 firmware console or that there are no other version of PS3s available in your area, i suggest buying on earlier CECH models, like CECH-25xx and clearly stay away with CECH-251x! You might also want to check the console with this sticker instead of this. Notice the bold part? dekoslav has confirmed that the bold one can be downgraded."
Guys, be careful before making a PS3 purchase from now-on... now watch a wave of returns to stores, and people postings of Sony blowing e-fuse, or other methods.
Also I've heard that the downgrade process works half way and then it bricks, but you can return it to 3.50... so for now those units can't be downgraded the usual way...

I got a CECH-2501 from Costco in Canada that came with 3.50 and after spending the whole daying trying to downgrade it refuses to do so. It was built in October, but no downgrade firmware works tested every single one from 3.15 to 3.40, debug and of course the modified 3.41. The only file it will take is the 3.50 with file1 of course.
I heard rumours there were some that you could not upgrade but this is no rumour, it needs to put on all the news pages as everyone still claims 3.50 is downgradable.
