ok but i am wondering is you don't have it can you still play games installed with brazillain method online and can you still use non legit DLC
i read through tall this stuff befroe but i have forgotten it because it has been awhile and i have not been using the console
For non-legit DLC support you must patch signatures, you can do it by 2 ways: Browser or Haxchi.
Haxchi is faster, you can set it like me and 1 click and it's done, if you do it by browser, you must go to the page, launch HBL, then select the patcher, wait for return to patched menu.
Or you could do CBHC (with Haxchi), and directly patch on boot, so you'll be always on a patched menu and you could install HBL/WUP/Loadiine to the menu and launch it safely from there.
