PS3 3000k and 4000k
 

Hi fellas!
I know I might be asking a great noobish question but...why isnt work being done on these models in a CFW level? I know that they bring 3.55+ base fw but is it really an IMPOSSIBILITY to bring them to 3.55? or is it that work isnt being done to do it?!
Im worried because I sent my 2000k to warranty and I think I might get a 3 or 4k :(!
Thanks in advance...

there are work just nothing successful yet.

because the ps3's with METLDR have been hacked already..
imagine yourself hacking a 3K or 4K device.. you'll need to get trough METLDR '2.0' first ( AFAIK, '2.0' has not been hacked yet, and probably never will cause the rest should work the same ( correct me if i'm wrong though ) )
