128w ago - Today we received word and videos from bx1199 of the E3 Team and sk group that E3DIY.net has made available an E3 Card Reader PlayStation 3 Firmware 3.50 downgrader, while PR0r also let us know that OzModChips (linked above) is now offering an Infectus PS3 Mod 3.50 Firmware downgrade service as well.
With this bin you can get the PS3 into service mode and downgrade using the previously released files to downgrade to 3.41 and below.
To quote from their page: "Thank you for using E3card Reader PS3. Today we will bring you a big surprise: the E3-Downgrader for E3card Reader. Yes it's THE downgrader which can turn your 3.5 PS3 down to any version you wanted, i.e. the 3.41.
