XXKP1 — Official Ice Cream Sandwich Firmware for Galaxy S2 i9100 Leaked!

XXKP1 Galaxy S2

Here we go — the title of first ice Cream Sandwich firmware leak for a non-nexus device belongs to a Samsung device, Galaxy S2. Yet again, much like it happened with Android 2.3 last year when Galaxy S firmware — XWJV1 — leaked to public. Heck, even Google’s own Nexus S is yet to receive an official release/leak!!

And this time, it’s the Samsung’s rockstar device, the international Galaxy S2 i9100, which took the honor of first leaked Android 4.0 firmware — v4.0.1 to be precise.

The leaked firmware is dubbed as i9100XXKP1, or XXKP1 if you prefer, and is flashable from Odin, the PC software we all know and love to use to flash firmwares.

The XXKP1 has ben leaked by the lucky guys over at SamMobile, who have been our traditional — and reputed — source for leaks since the days of Android 2.2 firmwares for good ol’ buddy, Galaxy S i9000.

Although XXKP1 has been leaked, the flashing of the same has not been recommended. But you know us, we’re downloading and we’ll be flashing this pretty soon, and will let you know for definite what’s in and what’s out.

Speaking of which, lovely TW4 is there (even though stock android launcher in ICS is pretty good now), and all basic stuff like Calls, SMS, Internet and other usual stuff is said to be working. The problem seems to be with random reboots, which is why samfirmware guys are not calling it a “CUSTOM” and not a proper firmware which they mostly term their leaks. Also, the kernel used in this firmware is insecure, thus this has been labeled as a CUSTOM rom, rather than the usual firmware, although we’re calling it a firmware going by the naming and source of the leak itself.

If you insist on trying the firmware yourself, the download link is below. Just know that this will void warranty even though it’s Samsung’s firmware, because it uses an insecure kernel. And YOU TAKE ALL THE RISKS ASSOCIATED WITH THIS. Be sure to backup important data. Our Odin flashing guide will follow soon, btw, so wait of you can.

    the steps worked, thanks.nhere’s what i noticed:n1. the wireless can only be activated through going to settings (can’t from the dropdown menu)n2. when the screen is locked i can’t recieve callsn3. the 3G connection is not workingnand sometimes “Settings” “Contacts” close with errors.nni guess this release still has some issues they must workout, but all and all it seems very nice.i’m back now to 2.3.6 which i realy like.

    The TouchWiz UI eats away the visual richness of stock ICS!

      I’m not against TW4, it was the best launcher so far. But yes, it’s next to ICS launcher now. I hope we’ll get simple apk (or cwm zip) to install Android 4.0′s gorgeous launcher along with TW4.

      And I think settings screen and other ICS goodness is as it is. Which is good.

      • abhishek raut

        yaaa….even i like TW4 vry much….but as most of us who has tried previous alfa build of ICS will surely would not like to go back to the good old TW4 once we taste ICS stock launcher !!! ;)

        • Athan

          Did any of you guys manage to install this? Did you find any step-by-step installation guide for this? Thanks..

          • abhishek raut

            once u download given ICS rom file.extract it.

            I have flashed xxkp1 already through Odin. My phone is crashing very often. Battery is depleting fast. Very much unstable. I want to go back to 2.3.4 is it possible. Please guide me

            Search this site for xxkh3 and install that using the guide. It’s based on Android 2.3.5 and is a very good Samsung firmware. Btw, I think I provided link to that above too, after the guide.
