    • arafat21

      You don’t need to do anything other than what we mentioned.

      • imteyaz

        lol, it seems like you are a nob , always do your homework before giving any advice. Chao ;)

        • arafat21

          And why you think so? You should know official firmware installation procedure restore everything if your device running on official firmware earlier. We flash ROM and custom firmware regularly but may be you have better knowledge than us.

    • imteyaz

      Yes, it is always advised by the experts that u should factory reset your phone before & after flashing any rom . As it might conflicts with the earlier version of the rom , Also it will clear any cache file left over by the earlier version which will affect the smoothness & response of the phone.

  • piet

    I flashed it and it worked great. Even my apps and data aren’t gone. No I have to gain rootaccesss

    • arafat21

      Wait little, since this is very new firmware than what we have earlier (4.0.4) we have to wait for a pre-rooted kernel or something similar.

  • guddu

    installed on sgs2 gt-i9100 in india….if you are upgrading from custom rom please do data wipe and factory reset….working very nicely …no multiwindow though

    • arafat21

      Thanks for your input @guddu. It surely encourage other to do the same safely.

      • guddu

        thanks @arafat21:disqus for your great support…..

  • Kym Morris

    I already flashed an unofficial version (XXLS8) and when I tried to flash this official one last night, it all appeared to work correctly, but when the phone comes back on, nothing had happened! Any idea?

    Thanks

    • arafat21

      Just check your About devices under settings to see if your phone updated or not. Both are Android 4.1.2 Jelly Bean so you won’t see much change here.

      • Kym Morris

        yep, definitely didn’t update. main reasons I want to are that there are a couple of bugs in the version I use and also I’d like to go back to an official version for the benefit of my warranty.

        • arafat21

          Follow above guide to update it. This will also help you get back your warranty once we reset flash counter to 0.

        • imteyaz

          factory reset your phone & clear partition in recovery mode before flashing the rom.. i’m sure you will not regret after flashing this Rom. it is the most stable rom released by the samsung for S2 i9100 , All the best ;)

  • Milan

    Can i install this update on network locked phone?

    • arafat21

      Not sure about that as network usually have own modem. What’s your network and Country? We will find an original firmware for you so that if this firmware don’t work the way you want, you can always roll back using your original firmware.

      • Raul Roquez

        Hello arafat21, my question is the same. My S2 is locked on Orange network, Romania. Will this update work ? Will I lose the waranty?

        • arafat21

          If you own a network locked device then you shouldn’t try this else you have to find a supported modem to receive calls and other carrier related service. Installing official firmware won’t void your warranty.

  • Stuart Young

    update went without any problems, however kies is saying “Your Device’s current firmware version is not supported to update firmware via kies” anyone know why this is? (its the latest version of kies: 2.5.1.12123_2)

    • arafat21

      The firmware currently available in certain country. You will see the same massage until Android 4.1.2 Jelly Bean firmware available for your country via KIES.

  • elatos98

    I live in greece. This update will work? Tnx

    • arafat21

      As this firmware isn’t carrier branded, it should work.

      • elatos98

        Tnx for the quick respond. I will take it a look…

  • elatos98

    The contents of my internal sdcard will be deleted, after flashing this rom?

    • arafat21

      As this is an official firmware it shouldn’t delete anything on your internal SD CARD but still backup is recommended.

    Major problems after flashing this version turns out the rooted kernel that was recommended completely fubard the phone , I ended up having to do a complete wipe and reinstall (everything wiped) and installed the jeboo kernel which actually works and now it’s ok although having loads of problems with the camera which worked perfectly on ics and not being able to get rid of the “use motion” annoying reminder.. Beware

  • santhu

    • arafat21

      Yes you can.

      If its carrier unlocked device then it should work. We really don’t know what’s going on.

  • CHRISTIAAN VAN AARDT

    Hi there. I’m in South Africa and would like to run this ROM. How do I check if my phone is networked locked, and if it’s not will this ROM work with South African Vodacom network. thanks

    • arafat21

      Network lock device means, you bought the device from a carrier and you can’t use any other SIM but only what your carrier (such as Vodafone) given. If that’s not the case then you can flash this firmware without any problem.

  • arafat21

    Try reflashing the firmware then.
