Jun 01, 2007 If you have a read of this tutorial here: PSP 6.61 Custom Firmware Install on any PSP it will explain how to update your PSP and install the 6.61 CFW. InsaneNutter, Oct 29, 2019 #3. Occupation: Programmer. Location: Behind You. Following the release of 6.61 PRO-C f3 here are some more updates regarding the PSP. First up is the update and release of 6.61 (L)ME-2.3 CFW by Rahim with all the usual flavors one can expect. Do note that these recent firmwares are not permanent custom firmware builds.
Psp 6.31 Hack
Chronoswitch Downgrader
https://lolhax.org
[VERSION 7.0]
-> Added support for Infinity
[VERSION 6.1]
-> Added support for 11g units to 6.60
[VERSION 6]
-> Added support for 6.61
[VERSION 5]
-> Added support for 09g units to 6.20
[What does it do?]
Allows users who are incontent with their firmware to downgrade to 6.20 using the Sony Updater.
[How do I use it?]
Copy the 'PSP' folder to your PSP. The downgrader is 'signed' and can be launched from OFW XMB. You need to copy the 6.20 update to PSP/GAME/UPDATE/EBOOT.PBP and for PSPgo it must be the eflash it is placed on. After setup run the downgrader and follow the onscreen instructions.
[What does it technically do?]
6.20-6.35: It uses the utility/power exploit to gain kernel access and reboots into the updater with a special PRX running. This PRX uses the pspdecrypt functionality to decrypt the updater PRX when needed. This allows the updater to boot in the newer firmwares.
6.38/6.39: It uses my http_storage exploit to gain kernel access. Basically, http_storage has a vulnerability in it, where I can write -1 to anywhere in memory.
6.60: Uses sceNetMPulldown to gain kernel access.
6.61: same as 6.60 (only certloader kexploit is patched in 6.61)
[I'm a dev, sup?]

Psp 6.31 Cfw
Psp 6.31 Cfw Diesel
I was beginning to think our PSP section would remain dormant forever, but PlayStation Portable developer Davee has just released PSP 6.61 Infinity Hybrid Firmware alongside a 6.61 LME and PRO CFW Patch Install Guide video below from The Zett!

To quote from his Blog: Release: 6.61 Infinity
Here we are at last, the release of 6.61 Infinity. It’s been over 11 years since the PSP was released back in 2004 and it’s somewhat impressive how long this device lasted. There is no definitive end to the representative scene, it just gets quieter and quieter.
I’m not claiming this releases is the end of the PSP, but it is for me. I’ve spent the last few years working on individual work on the PS Vita and other projects and coming back to the PSP in October 2014 to begin this project was definitely nostalgic.
The goal of this project was to bring the missing component of permanent CFW to the new PSP models and firmware. In this regard, I somewhat failed; PSP E1000 is not supported by Infinity due to a lapse in my judgement.
You see, I did all my PSP work up until 6.31 where I setup “base”. I was still working on the PSP when 6.60 was released, but porting my tools was laborious and I just stayed behind. The exploit found in 6.31 was used natively on this firmware, and until I did little more research when things didn’t work on 6.60 the hard truth was that it was patched in 6.35. This mistake (obviously) didn’t stop me from developing infinity, but it certainly was a large disappointment.
Some features have been temporarily removed due to some risks that will be corrected later, namely the update feature within the bootloader configuration app. You can still update to the latest version using the standard infinity installer. These features will be reintroduced when the risks have been corrected/confirmed. Remember you need the 6.31 and 6.61 updaters for system you will install the firmware on. Enjoy!
From the 6.61 Infinity About page, to quote: Custom firmware was typically achieved through a bugged 1.50 subset and loaded a newer firmware on boot. Later, this method was improved through Pandora and allowed the (then new) slim PSP to run custom firmware too. A breakthrough in 'code-signing' lead to the development of a 6.20 custom firmware for PSPgo and PSP 3000. Unfortunately, not all devices these days can use 6.20 firmware.
To solve this, I present 6.61 Infinity. By abusing a bug in 6.31, 6.61 Infinity utilises a similar technique to the old 1.50 firmwares to provide an upto-date custom firmware for all devices, excluding the E1000 (so far). Infinity itself is not a custom firmware; instead it allows the flexibility for users to install any compatible custom firmware they wish.
For convenience, Infinity includes built-in functionality for both PRO and ME. Use the Infinity Configurator to update infinity and choose which custom firmware to boot into on start up.
This is my final farewell to the PSP. Bug fixes will be provided, but after 12 years of PSP, this is where it ends for me. I plan to continue work on the vita and start some new, exciting projects. To keep up-to date, follow me on twitter: @DaveeFTW. If you're interested in the technical write-up, check out my blog.
Cheers, Davee
Installation
To install, copy PSP directory from the Installer download below to your PSP. Place the 6.31 and 6.61 updates named 631.PBP and 661.PBP respectfully into the MAKER folder. Run the maker application.
If successful, there will be a DATA.MFC file in the MAKER folder. Copy this to the FLASHER folder and run the flasher. After this your device will reboot and you'll be in Infinity! From here, install any CFW you wish and activate the permament patch in the Infinity Configuration app.
Here's a how to covering 6.60 plugins on 6.61, to quote:
I’ve been asked this question a lot and in most cases it would be very difficult to have a generic solution to a problem like this. Usually the difference between two firmware versions is significant enough that a plugin tied to particular version has to be manually updated by a developer in order to work on a newer firmware. Fortunately, 6.61 and 6.60 are so similar, I can release a plugin that will fake the version back to 6.60.
I’ve only tested it with a few plugins, but seems to work as intended. I am not sure if there is a lot of 6.61 plugins, but you need to make sure your seplugin text file is ordered in the following way:
The method used to patched the version is incredibly simplistic and could do with refining, but I’ll leave that to the eager reader. Source is in the package (linked above).
