Of course, it comes with Samsung’s TouchWiz UI on top, with Ice Cream Sandwich Android 4.0.3 running underneath. It is now officially available through Kies, but for those wishing to flash it manually on their Three branded Galaxy S2 can do so by following the step by step procedure given below.

Pre-Installation Requirements/Tips

  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
  2. If you have Samsung’s PC software Kies installed, un-install it first because it may interrupt the flashing process.

How to Install XXLPQ on Three’s Galaxy S2 i9100

  1. Download the XXLPQ firmware.
    Download Link  |  Filename: I9100XXLPQ_I9100H3GLP2_H3G.zip  |  Size: 399 MB
  2. Now, extract the downloaded file I9100XXLPQ_I9100H3GLP2_H3G.zip (from step 1) to any folder, you’ll get these 2 files:
    1. I9100XXLPQ_I9100H3GLP2_I9100NELP2_HOME.tar.md5
    2. SS_DL.dll (simply ignore this one)
  3. Now, download the Odin software which you’ll need to flash the XXLPQ on your Galaxy S2 i9100.
    Download Link  |  Filename: Odin3 v1.83.exe
  4. Power off your phone and also disconnect it from PC if it’s connected, and don’t forget to keep phone’s battery above 50%, just to be safe. After the screen goes off, wait for vibration to confirm complete switch off.
  5. Boot Galaxy S2 into Download Mode in order to flash the XXLPQ firmware using Odin. For this, press and hold these keys together: Volume Down + Home + Power, you’ll get a Warning! screen.. press Volume up to continue to enter download mode.
  6. Open Odin (from step 3) — double-click the Odin3 v1.83.exe.
  7. Connect your phone to PC now. You should get the message “Added! !” under Odin’s message box in the bottom left. If you don’t get this message, then probably there is a problem with drivers. Make sure you’ve proper drivers installed. See point 3 above under Pre-Installation Requirements.
  8. Now, in the PDA tab in Odin, select the file you got in step 2.1 – I9100XXLPQ_I9100H3GLP2_I9100NELP2_HOME.tar.md5.
  9. Important! Do not touch any other button or make any other changes in Odin except selecting the required file as given in step 8.
  10. Now, hit the START button to start flashing XXLPQ firmware. When the flashing procedure is finished, your phone will automatically reboot — and when you see the Samsung logo, you can safely unplug the cable. Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of Odin.IMPORTANT Note: If ODIN gets stuck at some stage and doesn’t seem to be doing anything, do this — disconnect the phone from the PC, close ODIN, remove battery, re-insert it, turn phone on in Download mode again, and do the procedure again from Step 6. Same if you get FAIL in Odin.
