It is because the updater built into 3.56+ OFW checks for modified pups (cfw). You cant mod a 4.21 pup, sign it and install it. It wont work.

Plus if your console is a late 2500 series or a 3000/4000 you will have LV0.2 not LV0, so what we have leaked out now wouldnt work anyway.

I'm assuming a new exploit would have to be found until this is available for higher firmwares?

This is correct. KDSbest and Naehrwert both claim to have methods ready for 4.21 IF an exploit can ever be found that slips past hypervisor/supervisor

its just a waiting process now...with the leak will come fixes for 3.55 for all new games...resident evil 6 fix has just been released...others will follow..and this is just the tip of the iceberg...give it a couple of weeks and let the devs rip 4.21 apart and get all the keys...then the fun begins

No body know. Time will tell.

I can give you a POC that negates what you have just said, JFW DH 3.56.
Also, something that should be epmphesized, ANYONE can modify LV0 as he wishes to , since the PRIVATE KEY was able to be calculated (due to the random number fail and the reason that bootldr wasn't modified).

Plus if your console is a late 2500 series or a 3000/4000 you will have LV0.2 not LV0, so what we have leaked out now wouldnt work anyway.

To my knowledge, every console has the same lv0. Just the new ones have an extra check of lv0.2 by the bootldr.
So theoretically, for every downgrade-able console, you can make your own custom pup even on latest ofws ( it just needs to be patched a lot but can be done in the same concept of the "3.56" cfw).
But if you try to use it on newer consoles, then most likely it will cause them to brick.

"3.56+" = ">3.56"

I should have worded it better... but it doesnt necessarily negate what I said.

Do you have reference to LV0.2 on devwiki? I cant find the pages to see where LV0.2 fits in exactly.

I don't think it's 100% accurate but maybe this is what you're looking for http://www.ps3devwiki.com/wiki/CoreOS

But still, you are missing the whole point of having lv0 private key.
Just think about it for a minute, you can modify lv0 the way YOU want, with your own "customed signed loaders"...I think that says enough to what can be done with lv0 keyset .

cheers

Thank you

Having taken a look at it, I am compelled to agree with what you are saying.

LV0.2 is loaded by LV0 on 3.60-4.30 FW.

I thought LV0.2 replaced LV0 somehow, not that it was added to the chain of trust.

so basicly,, patching out the security checks inside lv0 could bring us 3k / 4k owners a bit further to victory?
