Samsung Epic 4G finally gets a stable release version of the Gingerbread Firmware, which was leaked in the form of EF02. The firmware is a stock one and good for daily use.


Following is the details of the leaked firmware:

  • Phone Model: Samsung D700
  • Firmware: D700EF02
  • Android Version: 2.3.3
  • Build date: June 2011

Now that you know the particulars of the firmware, let’s get it running on your Epic 4G.


1. Download Android 2.3.3 Gingerbread EF02 ROM for Epic 4G. Use password ‘’ for extracting the RAR file. You will have three files in it.

2. Download ODIN flashing tool.


Turn off the phone completely and boot into ‘Download’ mode. You can do this by pressing and holding the ‘1’ key on the QWERTY keyboard and ‘POWER’ buttons together.

Then run the ODIN exe file that you earlier downloaded. Connect the phone to computer using USB cable. You should see yellow COM box in ODIN now. This means that USB connections are OK, and you are good to go to the next step. If the yellow COM box lights up as shown in the image below, you need to install Samsung drivers on the computer. Alternatively, you can install Samsung Kies software that will take care of USB drivers on your computer.


In ODIN, click ‘PIT’ button and choose the ‘vitory_8G-100528.pit’ file located in the unzipped EF02 package. Click ‘Bootloader’ and select the ‘SPH-D700-EF02-8Gb-REL-DebugKernel.tar’ file. Then click on ‘PDA’ button and choose the ‘SPH-D700-EF02-8Gb-REL.tar.md5’ file.


The ODIN options should be same as shown in screen-shot below:


Now you are set to go. No way back from here, we advise you to cross check all the file selections again. Once everything is right, go ahead and click ‘Start’ button and wait for the installation to finish.

After the installation is complete you will see ‘PASS’ green lighten box in ODIN. Now disconnect the USB connection.


Your phone will now reboot automatically into the new Android 2.3.3 Gingerbread EF02 firmware.
