Hey guys, sorry if there is a post for this already. i couldn't find a match myself so I thought I would post. So I have a S2 GT-I9100M and I downloaded kies and tried to upgrade firmwares. I am still running gingerbread or whatever its called (yes it asks me if i want to upgrade when i plug in the usb). Kies will download the firmware then when its at 100% it will crash and close the program. I have tried probably 30 times. I also deleted and reinstalled kies. I also formatted my phone. This is driving me insane. I would appreciate any help. Thanks!
