New PS3 METLDR Revision in CECH-2504 May Block Downgrading


137w ago - Today the Spanish PlayStation 3 developer dospiedras1973 who recently revealed both the PS3 Firmware 3.6x Downgrade via Infectus and PS3 3.7x Downgrade for Slims and Fats with NOR Flash has discovered what he believes may be a new PS3 METLDR revision in a CECH-2504 console (shipped with 3.60 Firmware) that blocks downgrading.

Below are his findings, roughly translated: New revision of blocks metldr downgrade for that guys, I found a console factory cech2504 with fw 3.60 and I found this:

In Plaintext:

The console in question was a cech2504 with Datecode 1B. I guess that's where that will forward all Datecode and not downgrade for the moment

Lookin through the notice and the toil of extracting the rules and be 6 hours trying the downgrade in different ways

I am assuming this is the 'unhackable' model Sony claimed? Does this downgrading include a complete reflash, like the 360s?

Because then you have the ability to upgrade when you want to play a game which requires 3.60+ Keys, then downgrade when you want to play your library of games on the HDD.

It's essentially allowing you to use 2 different FW's - an OFW for 3.60+ games and a CFW for everything else.

People won't be downgrading pre-3.55, the most likely scenario for most people is going to be:

3.55 CFW
Upgrade to 3.60+ OFW
Downgrade to 3.55 CFW
Upgrade to 3.60+ OFW

Both will require you opening up your PS3 anyways. So like Ezio said, if you're good at soldering, save yourself some money and use Progskeet.

You have a slim, the question is simple. If you're good at soldering you can take progskeet, if you aren't able then you take E3 when it comes out.
