PSP: First hacks for the new Firmware 6.61 – PRO CFW & Downgrader updated!

After confirming that the Firmware 6.61 has barely changed (compared to firmware 6.60), developer Qwikrazor has updated the Pro CFW (partly) and the 6.60 Downgrader (once again, partly) to support the firmware 6.61.

The ME & LME CFWs are currently being updated as well.

If you ask why I wrote partly behind the PRO CFW and Downgrader, then you’re asking the right questions.

At first the PRO CFW: I said partly because Qwikrazor did not update the cIPL Installer for the PRO CFW (only supports PSP 1000s & non-88v3 2000s), which means there is not “full CFW” for firmware 6.61 as of now.

PRO CFW should properly work as a temporary CFW on any PSP (be it a 1000, 2000, any of the different 3000s, an E1000 or the Go), though.

Now about the downgrader. The downgrader is capable of downgrading PSPs from firmware 6.61 to a lower firmware, but it is currently not capable of downgrading from 6.61 to 6.60.

You will have to downgrade to 6.39 and then update to 6.60, if you really want to return to firmware 6.60.



Since the PSP E1000 can only install the firmwares (6.50 as pre-installed, no installer available) 6.60 and 6.61, and the downgrader can not downgrade to 6.60, it (the PSP E1000) is currently not supported by the 6.61 downgrader.

Thats pretty much it. We expect that the PRO CFW cIPL Flasher will be fixed in the future, and a newer version of the downgrader be available soon~ish.

If you prefer the ME or LME CFW, then be patient, since it is already being updated to firmware 6.61. No words about the 6.60 HEN, though.

Here is PRO-C2 for 6.60 and 6.61 from the latest commit on the Pro CFW repo, 16-12-2014.
The CIPL flasher is left out intentionally for 6.61 (causes a brick).

This is a mod (hex edited) of the 6.60 Chronoswitch Downgrader by Davee/some1.
I only tested it on a 1k model, I couldn't downgrade to 6.60 from 6.61 (maybe corrupt updater), but I was able to downgrade to 5.00 from 6.61, 6.20+ might work, haven't tested it though.
