* A Samsung D500 Flash cable (not the Data cable!)

* A 9 Volt Battery for the Flash cable
* The Corona-Downloader > available in misc-section

II. Backup Guide

First thing you need to do is make a backup of your own firmware, so that in case the flashing of the new firmware fails, you can still flash your old firmware back. Now let's get started.

* Connect the flash cable at a COM-Port on the back of your computer.
(Check your settings of the COM-Port at the Hardware Settings, the Baud-setting must be at 115200)
* Conect a 9 Volt Battery on the Flash Cable.
* Remove your Sim-Card from the phone and put the battery back.
Please note: The battery must be completely loaded before the flashing process!



* Start the Corona-Downloader, choose the COM-Port (1) where you have mounted the flash cable on and select 115200 at Serial-Port (2).
* Click on START (3) in Corona-Downloader. "POWER ON the PHONE" should come up in the window. Now push the Power-Button on your Phone, and start up your phone like you normally do it. Now something should be happening in the window of Corona-Downloader as it's searching the settings of the phone. This takes about 30 seconds.
* Push Explorer at NAND Flash Operation (4). A new Window comes up. Here, you choose NAND Full Dump. Another window comes up. Choose a place on your hard disk where you would like the Backup to be saved, and then choose a name for the file. Click save and the backup should now begin. It takes up to 2,5 Hours and the Backup-File will be around 130 MB.

III. Flashing Guide

For the flashing process it's almost the same as the backup guide so this'll be easy

* Connect the flash cable at a COM-Port on the back of your computer.
(Check your settings of the COM-Port at the Hardware Settings, the Baud-setting must be at 115200)
* Connect a 9 Volt Battery on the Flash Cable.
* Remove your Sim-Card from the phone and put the battery back.
Please note: The battery must be completely loaded before the flashing process!

* Start the Corona-Downloader, choose the COM-Port (1) where you have mounted the flash cable on and select 115200 at Serial-Port (2).
* Click on START (3) in Corona-Downloader. "POWER ON the PHONE" should come up in the window. Now push the Power-Button on your Phone, and start up your phone like you normally do it. Now something should be happening in the window of Corona-Downloader as it's searching the settings of the phone. This takes about 30 seconds.
* Select BIN+TFS (4) at Corona-Downloader. Now search for the BIN (5) and TFS (6) on your hard disk. Once you're ready to start flashing, click on Download (7). The Flashing now begins. Flashing the BIN takes normally 35 Min. and the TFS takes 53 Min., that means 1,5 Hours in total. Once finished, a "Download Complete" message appears on your screen .

After you have flashed the phone you can remove the flash cable. Then insert the SIM-Card and start your phone for testing.
Once you started your phone, you can use the code *#1234# to check if the new firmware is correctly installed.

Photos, Ringtones, pictures, videos and mp3"s remain on the phone and the IMEI also remains the same.

Good Luck.
