Just received PS3 slim CECH-2504A with datacode 1A.
Connect e3-flasher, backup firmware, check it with FlowRebuilder.
Then press "downgrade". When process finished - I received brick.

I restore bumped firmware and console turns on!

Then I patch dumped firmware with dospiedras_v2 and flash it with E3-flasher.
And... brick.

There is my NOR dump: http://www.megaupload.com/?d=D1SG7J46

Is it downgradeble? Or I must forget about downgrade on this consoles ?

I have a 2504B can i use E3 flasher

Well, if it came with 3.60 or higher when you first bought it, then there's nothing you can do with it, until KaKaRoTo releases his 3.73 jailbreak.

I downgraded some consoles 2508 with datacode 1A.

This console is first my 1A-console which do not want to be downgraded.
(this console has metldr, not metldr.2)

Have a look on the Wiki, explains various examples.

I read it before.
ps3devwiki says that 1B non downgradable . But I have 1A with "metldr.1". All examples on ps3devwiki with new metldr are downgradable.

Use the MinVerChk PUP to check your minimum version. (it wokrs in 3.60+)

One more console which briks when I try downgrade it with E3-flasher.
CECH-2504A data code 1A. Factory firmware 3.56.
http://www.megaupload.com/?d=GYZ8PHFV - there is my dump (3.56).

How can I downgrade it? Teensy or progskeet?

one more problem:
I dump NOR, tried downgrade it - it bricked.
I restored NOR with first 3.56 dump - it booted correct.
I updated it to 3.73 and tried downgrade it - it bricked too (I did not make 3.73 NOR dump before downgrade).
And now when I restore first 3.56 NOR dump - console bricks too!
Why? How can restore console?

It's only my opinion. May be HDD 3.73 conflicts with OFW 3.56?

You should have been backup HDD 3.56 with dd if.. of.. on Linux..

I upgrade to 3.73 with "another" HDD and I have original 3.56 HDD.
It does not start without HDD too.
