Hurray, finally the official Andorid 4.0.3 Ice cream sandwich has landed on Samsung Galaxy S2 today. The official ICS will be rolling out to SG2 users in Korea and Europe and following by all other countries. You may need to wait the ATO update for few more days or weeks. Why don’t try to update it manually. You can use Samsung’s PC Software Kies to update your ROM manually. You may have tried several custom ICS ROM on SG2 but this is OFFIICIAL ROM and should have minimal bugs. Let’s see how we can do it.
How To Install XXLPQ On Samsung Galaxy S2 i900
- Download the XXLPQ Kies firmware from this link →XXLPQ. Filename: I9100XXLPQ_I9100OXALPQ_XEO.zip | Size: 382.43 MB
- Now, extract the downloaded file I9100XXLPQ_I9100OXALPQ_XEO.zip (from step 1) to any folder, you’ll get these 2 files: I9100XXLPQ_I9100OXALPQ_I9100XXLPQ_HOME.tar.md5 & SS_DL.dll (simply ignore this one)
- 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
- 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 very very safe. After the screen goes off, wait for vibration to confirm complete switch off.
- 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.
- Open Odin (from step 3) — double-click the Odin3 v1.83.exe.
- Connect your phone to PC now. You should get the message “Added! !” under Odin’smessage 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.
- Now, in the PDA tab in Odin, select the file you got in step 2.1 – I9100XXLPQ_I9100OXALPQ_I9100XXLPQ_HOME.tar.md5.Important! Do not touch any other button or make any other changes in Odin except selecting the required file as given in step 8. Your Odin’s screen should look like this:
9. 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 the Odin. Screen would look like this (below) on successful flashing of XXLPQ.
IMPORTANT Note: If ODIN gets stuck at some stage and doesn’t get you PASS, 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.
Lastly, after you’ve got the PASS message, the phone will probably get stuckat S logo. If it reboots fine without getting stuck at the S logo, then okay, you’re done, skip to next step. Otherwise, worry not and do this:
- Boot to recovery mode — for which, first power off phone and after screen goes off, wait for 5-6 seconds, and then press and hold Home + Volume Up + Power keys together. Once you are in recovery mode, use volume keys to move the selection up and down and power or home key to select the option.
- Go to Factory Reset and select it. Select Yes on next screen.
- Now, go to Wipe Cache and select it. Confirm Yes on next screen.
