From the ReadMe file: This patch will take the original Rebug 3.55.1 PUP file and update it with both the official Update 0.1 and official Rebug Privacy Patch. NO other changes have been made! This is a diff patch only!
AS THE REBUG TEAM HAVE STATED: "If you choose to post links to our software that does not directly link to rebug.me we will seriously consider not release anything relating to the PS3. This includes Rebug and future versions of Rebug. We rely on visitors to our site that visit our ad sponsors to help offset the cost of the server."
DO NOT MIRROR EITHER THE ORIGINAL REBUG FIRMWARE OR THE PATCHED OUTPUT FILE THIS CREATES! GET THE OFFICIAL REBUG FIRMWARE FROM: rebug.me
The newly patched REBUG_355.1_PS3UPDAT.PUP should have a MD5 of: 7ED26897FA53D1925D385EB188A56D47
Also remember to use the Rebug selector to switch back to normal mode before installing, otherwise the version spoof will prevent 3.55 from being reinstalled.
