FLASHING A ROM, RADIO OR KERNEL VIA DOWNLOAD MODE USING ODIN

Odin can be used to flash image files or parts of your phone. You can flash something as simple as a boot image or a complete system. Everything is packed in a tar or tar.md5 file on your PC and flashed via Odin which is a Windows OS program.

a. Make sure you have your tar file stored on your PC.

b. Reboot your phone to Download Mode [shut down your phone, then hold down the Home + Volume DOWN Buttons and press the Power Button for about 2 seconds until a Warning screen appears. Press Volume UP to continue to Download Mode.

c. Connect your phone via usb and the first box at the top under ID:COM should turn blue and have some text in it. If you are using Download Mode on your phone for the first time then you will notice drivers being installed to use it.

d. The site or page you downloaded the file from will usually give you instructions to set Odin but if not you want to load boot/recovery/system files to the PDA location and have 'Auto Reboot' and 'F.Reset Time' ticked and nothing else.

e. Click on 'Start' to start the flash. You can see what is happening in the text box in the lower left.
