PSP Firmware 6.60 Downgrader Released

So since the PSP is hacked to shit — and Sony isn’t suing anyone who targets it — developer some1 has released PSP Downgrader v4. And in addition to 6.60 support you can now downgrade to anyofficial firmware, but — more on that after this…

This downgrader, originally developed by Davee for 6.31 and 6.35, which some1 ported to later firmwares — 6.38, 6.39, and 6.60 — now lets you downgrade your PSP not only to 6.20, but any official firmware (OFW) you so desire. Although with that, comes this: You can only downgrade to a firmware greater than or equal to the factory installed OFW when your PSP was purchased; this downgrade has not been fully tested with all the different PSP models and OFWs; I wouldn’t try anything silly, like jumping way back to firmware 1.50; we are not responsible if you damage or brick your PSP.

The firmware 6.60 downgrade is made possible by a (new?) kernel exploit discovered by Davee; that was then passed down to Zecoxao, who later made said exploit available to some1. So mad props to everyone — full circle!
