How do I get back to Froyo from Gingerbread? I'm running ZS1.71 now, but I was running LGBv.4 and when I plugged my phone into rsd, everything seemed fine, except when I tried to flash, it just said failed, without even making a backup image like it usually does at first. I am in bootloader and have the drivers installed. Anyone know what Im doing wrong? I'm on windows 7 if that helps.
