  1. Because the list of requirements is now complete, you can go on and download these files on the laptop: Odin 3.07. exe from this page and the new Jelly Bean 4.1.2 stock firmware from . These packages come pre-loaded with many files; these files must be a part of your notebook, so unzip the two.
  2. Make sure they land on the PC’s desktop, then do this: boot your Samsung I9268 in Download Mode by pressing and holding Volume Down + Home + Power, let go and press Volume Up when Android’s logo appears.
  3. You should do as follows next: open the Odin. Then make sure the handset is connected to the laptop via the USB cord. The only way this connection will work is if you see a yellow ID:COM box together with this message: “Added!!”. If no such thing appears on the screen, you should use another USB port; or try installing, again, the USB drivers.
  4. Here is what we ask you to do after the plugging is successful: click on PDA, find a file with CODE and opt for it, tap Phone, locate a file with MODEM in the name and select it, click on CSC, search for a file with CSC in the name, tap PIT and choose a file whose extension should be .pit.
  5. Now check Re-partition, F. Reset Time and Auto Reboot boxes. After applying this step, you should move on by tapping “Start” and then waiting for the flashing of the new firmware to begin.
