New PS3 METLDR Revision in CECH-2504 May Block Downgrading

[PS3 News]

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:

00 00 00 01 00 00 00 01 00 00 00 00 00 02 E8 00 00 00 00 00 00 00 00 40 00 00 00 00 00 00 F9 20 6D 65 74 6C 64 72 2E 32 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

In Plaintext:

..............è........@......ù metldr.2........................

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

So does this mean the E3 flasher will not work on these new consoles?

Anyways, I hope dospiedras1973 can find a way past this.

Sure, you can downgrade only in accordance with minimum supported firmware of your ps3.

[HeyManHRU]

Ok Thanks.

[shummyr]

All that they are doing is giving a minimum version that you can downgrade to.

Sony seem to have really got their act together after their earlier fail.

I have one ordered so i can take a look at it. I will have to do some testing. Got someone that works for a store and i get it at cost. SO if i mess it up then i mess it up. THanks

There is also another metldr.

• metldr (before datecode 1B) <- can be downgraded
• metldr (datecode 1B) <- can not be downgraded
• metldr.2 (datecode 1B) <- can not be downgraded

It looks like .2 does not apply to all 1B date-coded consoles - but 1B+ still cannot be downgraded.
