Well i didn't find anything on these forums about its release (i checked both russian and english forums, fluent in both) so i thought i'd post something. Anyways, it seems Mathieulh and DaX have discovered a way to dump the nand of a psp slim... They claim the project is private and would not be released to the public, but should be easy enough for other's to discover. The nand image was 66mb and did not seem to be decrypted (at least not to me) based on math's post.
Right so here is my reaction to all this: (i posted it in several other forums and am way to lazy to translate it into russian (i type at 5 words a minute in rus versus the hundreds i get in eng). :

First of as a coder myself i can tell you how possessive and proud some people can be with their work. There's nothing wrong with that, in fact it should be respected. For the rest of you ******* who want to b**ch about this maybe if you had been a bit more supportive you'd understand but now you should be grateful for any sort of release and if you're not then go crawl under a rock because odds are without this there won't be another exploit for a loong time.
Anyways, aside from that, personally i wouldn't get my hopes up for another exploit. Also regarding the save state buffer overload, it's highly unlikely that it is even possible on a psp because simply modifying the hardware a little would enable sony to add a switch that can block write access to the nand in game... Furthermore, i believe one of two things hapened: either a new service mode hack or my more far fetched idea is physically removing the memmory chips off the psp 2000 motherboard, hooking them up to the original psp and then running a 1.5 nand dump off of the mem card (using pandora) accessing the flash through the 1.5 kernel in a standard eboot (of course a driver change might be neccessary for the new hardware to be readable) such as booster's usbsss
