Downgrading Samsung Galaxy 3 I5801 to 2.1 (DDJG6-INDIA)

A lot of people wanted to know how to downgrade I5801 from 2.2 to 2.1.
If you wish to revert back to 2.1 once you get the official update from Samsung, here is how you can do it...

You need to flash the 2.1 firmware on top of any firmware.

Here I'm going to show how to flash the 2.1 firmware (DDJG6-INDIA) on your Galaxy3.

For installing any firmware on Samsung Galaxy 3 I5801(Apollo) you need the following prerequisites:
  1. You need to have the Samsung drivers for your Samsung Galaxy 3 installed on the desktop. (To do so simply install Samsung Kies from Samsung's official website)
  2. Make sure you have charged your battery, 50% or higher is preferable. (To be on a safer side charge your mobile to 100%)
  3. Make sure you have download mode working. (Turn off your mobile by pressing the power button, once switched off press and hold "power button + menu button + vol down button" simultaneously
  4. The next important point is to download the I5801DDJG6_Complete_Package.
Once you have all the things mentioned above you can now install DDJG6 on your Samsung Galaxy 3 in a few minutes.

Extract I5801DDJG6_Complete_Package.rar file with the password "".

On extraction, you will find a folder named "I5801DDJG6_Complete_Package" inside that folder there will be 1 folder("I5801DDJG6") and 2 files("apollo_0531.ops", "I5800_Odin_Multi_Downloader_v4.252.exe").

Inside the I5801DDJG6 folder there will be a single file by the name of "I5801DDJG6.tar", this is file we are interested in and is the actual firmware which we will be using later during flashing.

Kindly follow the instructions mentioned below:
  1. Enter Download Mode by pressing power button + menu button + vol down button simultaneously.
  2. Open ODIN and then plug in the USB cable.
  3. Ensure that you see something written in ID:COM after connecting your device.
  4. Flashing Steps:
    1. In ODIN Multi Downloader, there is an option "One Package" you need to have that ticked.
    2. The next step is the select the OPS and One Package files
      1. Select the "apollo_0531.ops" file in OPS.
      2. Select the "I5801DDJG6.tar" file by clicking One Package button at the bottom.

    3. Click on Start wait till you see pass in ODIN before you unplug your phone.
Congratulations!! You have successfully installed 2.1 DDJG6 firmware on your Samsung Galaxy 3.You can now upgrade your phone via Kies once the update is available.
