Installing firmware I9100H3GLP2 (XXLPQ) on Three UK's Samsung Galaxy S2

April 6, 2012

The latest update to hit the Samsung Galaxy S2 has already been released in some parts of Europe and now it’s time for users of UK’s mobile carrier Hutchison 3G UK (“Three”) to get the XXLPQ firmware update in the shape of I9100H3GLP2. The update’s main software version is still XXLPQ, but this update is only for Galaxy S2 phones on the said network. The update comes with TouchWiz UI and Android 4.0.3 Ice Cream Sandwich and can be flashed through Samsung KIES.

For those of on the Three network who would like to flash this update manually, you can do so using our instructions below and Odin3.


This update is only compatible with Three UK’s Samsung Galaxy S2, with model number GT-I9100. It is not compatible with other devices, such as the U.S. variant of the Galaxy S2, the Epic 4G Touch, the T-Mobile Galaxy S2, or AT&T’s Galaxy S2 and Skyrocket. Attempting to flash this update to incompatible phones may result in bricking.

  • Uninstall Samsung KIES on your computer.
  • Install Odin3 on your computer.
  • Make sure that you’ve installed the proper device drivers on your computer: 32-bit (x86) Windows | 64-bit (x64) Windows
  • XXLPQ firmware for Three UK’s Galaxy S2 (, 399 MB)

Some users have reported that you can’t set proxy information for a Wi-Fi connection. To fix this, when you turn Wi-Fi on, go to “Make a New Connection” and scroll down. Check “Show Advanced Options”. It should allow you to set any IP and proxy settings, different for each and every connection.

Congratulations! Your Three UK Samsung Galaxy S2 GT-I9100 is now running on build XXLPQ of Android 4.0.3 Ice Cream Sandwich.
