To quote: Finally I was able to find the time to port my dumpers on 4.21 CFW. There were some problems while porting from 3.55 to 4.xx and hopefully all of them were fixed.
These dumpers are not required to work with previous tool called Data Ddumper because they just write all data directly to the corresponding file on /dev_hdd0/tmp. All dumpers were tested on 4.21 REX and should works fine if you do the process correctly.
126w ago - Following up on the PS3 KLicense Brute-force Tool release, this weekend PlayStation 3 scene developer Flat_z has made available a PS3 Disc Key Dumper, Klicensee Dumper and corresponding Data Dumper with details outlined below.
The klicensee_dumper should speed up the gathering of klicensees. One of dumpers is an alternative to klicensee bruteforcer which released before because some klicensee keys cannot be bruteforced. Klicensee is used to resign/decrypt/encrypt self/sprx/edat.
As for the other dumper (for a disc key), I'm writing a tool to decrypt/encrypt saves and resign them for your console...
