New XXLPJ Ice Cream Cream Sandwich Firmware For Galaxy S II Leaks (+Installation Guide)
By on March 12th, 2012

Moments ago, SamFirmware leaked a new Ice Cream Sandwich based firmware for the Samsung Galaxy S II (I9100). The new firmware carries a build date of 14th February, which is pretty old. The last leak, XXLPH, had a build date of 9th Feburary. So yeah, don’t expect magical improvements in this leaked firmware.

I am currently downloading the firmware, and will update the post as soon as I flash it on my Galaxy S2. Until then, below is a step-by-step guide on how to install the leaked XXLPJ firmware on your Galaxy S2 -:

You need to have KIES pre-installed on your PC. Otherwise, ODIN will not be able to detect your Galaxy S2!

Step 1) Download ODIN and the leaked XXLPJ firmware from here and here, respectively. Extract the contents of the LPJ firmware zip file inside a new folder on your desktop.

Step 2) Start ODIN, click on the PDA button and select the ‘I9100_CODE_I9100…ship.tar’ file. Similarly, press the ‘MODEM’ and ‘CSC’ button and select the file with ‘MODEM’ and ‘GT-I9100-MULTI..’ in it name, respectively.

Step 3) 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 4) Connect your SGS2 to your PC, and wait for ODIN to detect the handset. When ODIN detects your phone, it will display a random COM:ID number inside a glowing yellow box. Do not touch any other option. Simply press the Start button and wait for ODIN to flash the LPJ firmware on your handset.

When the firmware is flashed, your phone will automatically restart. Keep in mind that the first boot will take some time so have some patient. For root access, download the LPJ version of CF-Root from this thread on XDA forums.

Credits To Chainfire for the rooted kernel and SamMobile for leaking the firmware!

Hopefully, we might see the near final Ice Cream Sandwich firmware for the Galaxy S II leak in the upcoming days!

Update: Ok! So I flashed the firmware on my Galaxy S II and things are definitely looking good. The firmware is pretty fast, and I have not encountered any lags whatsoever. People over at XDA forums are also reporting the same thing. I cannot comment anything on the battery life, since the firwmare was just released. I am still playing around with the firmware, and will update this post when and if, I find any bugs or changes.
