In the twilight years of the PlayStation Portable (PSP), Sony released firmware 6.61. It was a minor update aimed purely at blocking piracy and homebrew exploits. For years, the custom firmware (CFW) community was stuck on 6.60, because 6.61 offered no new features—only tighter security. That all changed with the release of Infinity 2.0 and the specialized CFW Pack by MrMario2011.
If you are looking to breathe new life into your PSP 1000, 2000, 3000, or PSP Street (E-1000), MrMario2011’s all-in-one pack is the gold standard. This article provides a deep dive into what this pack is, why it matters, how to install it, and how it transforms your PSP into the ultimate retro gaming handheld.
Warning: Modding your PSP carries a risk of bricking (turning it into a paperweight). However, the Infinity 2.0 method is safe if you follow instructions exactly.

Warning: If you have a PSP-1000 or early PSP-2000, you could also use the older "CIPL Flasher," but Infinity is safer and easier to uninstall.
You might ask: “Why not just use Chronoswitch or the official Davee installer?”
The Davee official installer requires you to manually download 6.61 PRO-C2, rename files, and sometimes you mess up the CIPL flasher for older PSPs. MrMario2011’s pack includes a CIPL flasher for PSP-1000/2000 non-v3 that is pre-configured to work with Infinity, preventing the "black screen of death." File: PSP 6
