The thing I'm wondering, if this is a 4.21 cfw, after we installed it, will it accept future .PUP signed with the old failoverflow private keys? This is something they MUST patch into the cfw otherwise whoever updates it will be deadend afterwards and even there is new cfw you won't be able to install it, only ofw fw would work. so a word of advice, if the firmware released don't rush out and install it, wait for confirmation first
oh well, i would b patiently waiting for the new CFW, cos i do really need it, been stuck with OFW 3.72, for those on CFW 3.55 pls stop with all the comments you should be grateful, cos you can do lots more with your ps3...
I'm really happy with this news. I've already told a friend (who has bought a PS3 recently) not to update... If this is only for 3.55 then I should reccommend those on 3.56-4.21 not to update as well, you'll probably be able to install the CFW in the future.
we only have private keys for 3.55 or below from fail0verflow, it's impossible to get new keys that work on newer firmwares so installing a PUP on 3.6+ ofw will not happen ever unless a new exploit is found. The other way is to downgrade your console with flasher to 3.55 first, problem is not all consoles (like 3000) are downgrade able. maybe you can downgrade to this 4.21fw on consoles that can't dg to 3.55 but I'm not sure.
