Hey everyone, I have been trying to upgrade my Captivate to Froyo the past couple of days using Kies Mini. I am on the stock ROM an I haven't roote my Captivate. I am running a 32-bit Windows Vistas OS and I can successfully install the Usb Drivers and Kies Mini. I follow the instructions on the Samsung Website but when I click on Phone Upgrade, I get this error. I've tried variations like putting in the usb cable in first, then starting Kies Mini; or turning usb debugging mode on and off, but I get the same error. Samsung Tech Support was no help at all an I haven't seen similar problems elsewhere. Anyone know what is wrong? Any help is appreciated. Thanks.
