Update Samsung Galaxy S II S2 firmware to Gingerbread 2.3.5 | Singapore firmware | IT Tutorial

Finally, I have my Singapore local set, Samsung Galaxy S II updated with the official firmware from Samsung. Rather than waiting for the official roll out of the firmware via Kies, I have obtained the packaged version and updated my set to the new Gingerbread 2.3.5 version. Below is the full instructions for the firmware upgrade.

Gingerbread 2.3.5

These are the files which you will need:

a) Samsung USB Drivers
b) I9100XXKI3.rar (specify the Password – samfirmware.com)

Phase 1- Preparation

1) Install the Samsung USB drivers





2) Unzip the main firmware file which will contain 5 files

3) Run Odin3 v1.85.exe file


4) Power off your Galaxy S2


Phase 2 – Upgrading and Updating

Special notes:

– Take Backup of your contacts messages and other data from your phone

– This procedure doesn`t format your internal memory. But messages, contacts and apps WILL be erased

– Shut down Samsung Kies completely prior the start of the upgrade

– This is not a root process and thus the warranty is not voided
