How to Update Singapore / Thailand Galaxy SII GT I9100 with Official DXLP9 ICS 4.0.3 Firmware

Galaxy S2 LogoSamsung Galaxy SII GT I9100 smartphone users of Singapore can now update with the latest version of ICS Firmware which is dubbed as DXLP9. This update can also be applied by the users of Thailand S2 users too. Please note that this is the Official firmware version which is released by Samsung. Just in case if you are in the beta firmware, then you can apply this official update so as to restore the factory warranty. Also, if you are in any of the custom firmwares or on the beta leaked firmwares then you will have to apply the update manually. This is the 4.0.3 version of ICS.

Disclaimer: Neither we, nor Samsung should be held responsible for any damage happened to your device in the process of following the instructions mentioned in this article. It’s very unlikely that there will be any issues but just in case if at all there are any issues then we are committed to help you in solving the same.

Rooting Information: Applying this update doesn’t mean that you need to root the device before & also the device will not get rooted after applying this update. Just in case if your device is rooted, after applying this update the rooting access will be revoked. We will soon come up with the rooting process at the earliest.

Over a period of this article we will be checking out on what are the list of pre requisites you need to follow along with the detailed guide to apply this update manually.

Essential pre Requisites:

  • In the process of applying this update, the data will get lost. So, it’s highly recommended to back up the same so that the same can be restored easily. You can make use of below mentioned steps so as to back up the data manually.

SMS – Use “SMS Backup & Restore app”,
Contacts – Sync with the Gmail application,
Call Log – Call Log and Restore
Images, Songs, Videos, Files – Copy to internal / External SD Card,
APN and MMS Settings – Note down from the path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names

  • Minimum charge left in the device should be at least 60% so as to ensure that device doesn’t get turned Off in the middle of firmware update.
  • Enable the USB debugging in your Galaxy SII GT I9100 from the path “Settings > Applications > Development > USB debugging”. The USB Debugging option should be ticked. USB Debugging Mode can only be enabled once you disconnect the phone from computer. USB Debugging should be ticked.

USB Debugging

  • Disable all the antivirus suites in your computer and uninstall the same in your device as these tools generally tend to interrupt the process of firmware update.

Assuming that you have followed all the above mentioned instructions, you can now proceed to the next page where we have summed up a detailed guide on how to apply this update.

    I flashed this FW about 2 days ago. It looks good and stable other than the battery drainage is faster than 2.36 in idle . The phone is also warmer at 118c during charge and it drops back to 87c when unplug the charge. Has any one experiencing the same thing?

    Hi Neela, can I use this to update my I9100 for Philippines? XXLPQ working fine but sometimes the phone hangs up then an error pops up “samsung-like error message”. I dont exactly recall the words but it’s something innate in the firmware and yes, I already wiped the cache/reset ages ago.

    Checking MD5 finished Sucessfully..
    Leave CS..
    Odin v.3 engine (ID:7)..
    File analysis..
    Can’t open the serial(COM) port.
    All threads completed. (succeed 0 / failed 1)
    Did everything in the guide by the book, the phone is indeed an i9100 runnung stock 2.3.3 as my Carrier Vodacom (South Africa) has never released updates so far, what am i doing wrong and what does this error mean besides the port cannot be opend. Using the front USB port on PC will try using other ports.
