12/11/11: Oiginal latest firmware download, DZKJ2
For those who need to manually download the latest firmware, here's the link http://www.multiupload.com/76EOEV1MD5

I have recently purchased Samsung Galaxy S2 i9100G.

I am facing problems with 2 aspects

1) Camera fails, (after the phone has been used for some time, if i take a pic, the camera hangs and i am forced to reboot the mobile.
2) Apmobile always running and consuming approx 40% of Battery.

can you guide me the difference between DZKJ2 & DDKI1 firmware. My Phone is currently on DDKI1. Should i update it with DZKJ2, what are the benefits of DZKJ2

Phone Details
Model:- GT-I9100G
Andriod Version:- 2.3.6
Baseband Version:- I9100GDDKI1
Build Number:- GINGERBREAD.XWKJ2

Regards,
Raj

Thanks for your quick reply. I have gone through your Guide, its very clear and east to understand for new users like me.

I currently don't want to install custom roms, hence i plan to update to current version.

When i tried by Kies, i got message as DDKI1 is updated firmware. Hence i plan to download DZKJ2 and update.

Now i notice
1) you have mentioned re-partition is ticked. Do i leave it like that?
2) do i have to enter recovery mode once i update? “Wipe Data / factory reset” and “Wipe Cache Partition”
3) Will i loose all my date (apps, contacts, sms, logs).

Thanks in Advance
