You can flash DDJG4 irrespective of the firmware you have currently installed on your Galaxy S.
DDJG4 is the official Indian firmware for Galaxy S.
This was the firmware that was pre-installed on the phone when the phone was first launched.
I recommend installing this firmware whenever you wish to get an official upgrade from Samsung Kies in India.
For updating Samsung Galaxy S GT-I9000(SGS) to Eclair 2.1 DDJG4 you need the following prerequisites:
- You need to have the Samsung drivers for your SGS installed on the desktop. To do so simply install Samsung Kies. Samsung Kies version 220.127.116.1153_99_3 can be downloaded from here.
- Make sure you have charged your battery, 50% or higher is preferable. (To be on a safer side charge your mobile to 100%)
- 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)
- The next important point is to download the complete flashing package. The I9000DDJG4 complete flashing package can be downloaded from here.
