October 24, 2012 // 11:13 pm - Following up on the PS3 LV0 (Bootldr) leak, PS3 4.21 EBOOT Resigner and PS3 4.21 LV2 Patcher today I have created a guide on how to resign (port) and sign PS3 homebrew for use with PlayStation 3 4.21 CFW.

Also below is a Resign Disc Game Files GUI by SliMDiCK (via diablothebest)

Required (Included in File Pack above)

  • PkgView
  • PKG Content ID
  • 4.21 EBOOT Resigner
  • psn_package_npdrm


1. Download the homebrew you want to sign for 4.21, Later, we must use PkgView to extract the contents of the pkg from our PC. Drag the pkg in the program, right mouse button on the folder and press extract to source folder.

2. Open the folder you just extracted, SDISABLER > USRDIR > EBOOT (SDISABLER in this example, for other pkg is different) click right mouse button and copy the reboot. Now we will need the 4.21 eboot resigner for the next step, open the program folder, and paste the eboot you copied earlier.

3. We launch the resigner, we select the operation 2 NPDRM resigner reboot, then press 2.

4. We will be asked to enter the content-id of the application, in order to obtain what we need is the program pkg content id.

5. Open pkg contet id, loaded the pkg, and once that you will see your id, just copy it and paste it into your resigner and hit enter.

6. Now go back on the resigner folder and copy now EBOOT.

7. Paste it in your pkg folder (SDISABLER\USRDIR).

8. Now after you have fixed the eboot, we need repack pkg; and to do this we need the application psn_package_npdrm . Open program folder and copy file in your pkg folder.

9. Before proceeding to Repack we must configure the package.conf file, open notepad and edit the data as shown in photo.

10. Now SHIFT+right click for open windows command and type "psn_package_npdrm.exe package.conf SDISABLER" where SDISABLER is the id of your game.

11. Done. Your homebrew is now signed for 4.21 CFW... Enjoy

I understand, but it's better to be safe than sorry

Some people went and upgraded, and bricks were the result, and not just for the recent cfw either.

Because I don't use my PS3 for homebrew or games much.. mainly for media and watching TV. the release of 4.30 sort of got me interested in trying a few things again..

People have different reasons why they do things differently to what you would do.

Why would you update without making sure everything was compatible first?

That's why I dont want to do anything until all homebrew including reactpsn works for 4.21 CFW or a stable CFW just like 3.41 rebug/3.55 CFW. I dont want to losing homebrew and reactpsn at all.

is someone remaking a PSIDPATCH for 4.30? since then even a resign version of PSIDPATCH is not working, I guess sony changed the offsets for where it stores its PSID so the program can't randomize it anymore
