To install the said firmware
Step 1: Download the official ice cream sandwitch
firmware and download ODIN,Extract the LPQ firmware zip file
inside a new folder on your desktop.
Step 2: Switch off your Galaxy S2 and re-
insert its battery. Now boot your Galaxy S2
in Download mode by pressing the Volume
Down + Home + Power button
simultaneously. Your phone will then show
you a warning. Simply skip the warning by
pressing the Volume Up button.
Step 3: Start ODIN, and then connect
your Galaxy S II to your PC. ODIN will
then detect your phone, and display a
random COM:ID number inside a glowing
rectangle box. Click on the PDA button,
and select the I9100XXLPQ_I9100OXALPQ_
I9100XXLPQ_HOME.tar.md5 file. It is the
only file inside the zip file that you
downloaded in Step 1 above.
Step 4: Do not touch any other option.
Simply press the Start button and wait for
ODIN to flash the firmware.
The firmware is pretty big (500+MB
extracted), and so ODIN will take some
time to flash it. The first boot after the
flash will also take considerable time. It
took nearly 10minutes for my Galaxy S II
to start after I flashed the firmware.
Update: Added some mirrors for the
firmware download link. For root access,
download and flash Siyah Kernel LPQ and
flash via ODIN.
Update 2: If your phone is stuck at the S
boot logo for more than 15 mins, re-insert
the battery and re-do the steps mentioned
above.
