- Now download a firmware of your choice from samfirmware.com.
- Make sure you have the phone’s battery charged to at least 40-50%.
Now that you have everything now you need to go and set Odin.
- On ODIN select the OPS button and load the Cooper_v1.0.ops file unto it. Ensure that the Auto-Reboot, Protect OPS and Reset Time is checked.
- Unzip the firmware .Zip file in a folder If you get have the contents in .TAR (or .tar.md5), Check “One Package” option on the left side & skip PDA, Phone, CSC, BOOT options & directly go to ‘One Package’ option. Browse for the .tar (or .tar.md5) file & select it.

I have Samsung USB drive installed, but when I put my phone into custom ROM download mode (power + volume down + home+), my Windows PC says the USB device is not recognized. Though the USB mass storage tool works perfectly fine. What is the problem?
