Just do what i did i got this from the Infuse forum on AT&T and it worked.
Samsung Infuse 4G
I too had the problem that everyone is having with kies mini and Samsung support, but I found a fix and it does not require gtg unbrick to be use..
Here is what I did:
1.Download the .md5 file from this post
xda-developers he captured it from kies mini. Download the file it will be called I997UCKL2-Homebinary.tar.md5 save it where you can find it like your desktop.
If you have a Mac, then I guess that you could unzip it and flash it thru heimdall, not sure of how to do this as I don't have a mac
2. Download and save Odin3 1.7 from here
Anti Virus Software - David Star Enterprises v1.7.exe to your desktop
3, When the .md5 file is done downloading it will be called I997UCKL2-Homebinary.tar.md5
4. Run Odin, make sure infuse shows up as a com port. Load the upgrade, which will end in md5, into the PDA slot
5.Place phone in download mode here is how you do this
1.Once the files are selected put the phone in download mode. (Pull battery, replace battery, press and hold both volume buttons while plugging in the USB cable connected to the PC.)
2.Once you see the device connected in ODIN, hit the Start button to begin the flashing process.
3.Once the process completes, the phone will reboot.
6. The phone think on the ATT splash screen that is normal with any update.
7. Welcome to Gingerbread. you can verify this by seeing the icons at the top in the tray will be smaller (i.e battery, signal, network,)
8. Go to menu-> About Phone -> Firmware verision will say 2.3.6(GB)
Baseband Version will be I997UCKL2
Kernel version will be 2.6.35.7-I997UCKL2-CL806505
Build Number will be Gingerbreat.UCKL2
9. Pass this around to every one you know that can't update their phones for kies mini including ATT rep they are lost on this as I had an encounter with one today where the samsung rep disconnected the chat with him well he was trying to help me.
10. Be nice to ATT they have no control over this update this is Samsung problem written all over it.
