PS3 SPKG Tool v1.0 for Windows and Linux (Mirror)
From the ReadMe file: SPKG Tool 1.0
Requirements:
- fail0verflow key folder
- spkg (3.56+) and pkg (0.80-3.55) key/iv
- disabled ecdsa check in spu_pkg_rvk_verifier
Usage:
- spkg in.pkg out.spkg_hdr
or
- spkg in.spkg_hdr out.decrypted_spkg -d
Thanks to:
- Fail0verflow for their tools
- Anyone that thinks replacing a coldboot logo means creating his/her own cfw

so now all CFW can run smoothly, without toggle activated and hdd replace issue is fix
btw you need spkg-key and iv from retail one to get this application working.
