Galaxy S2 Official Jellybean 4.1.2 XXLSJ Firmware Update with 50GB Dropbox Space

Procedure to Upgrade Galaxy S2 GT I9100 firmware with Official Jellybean 4.1.2 Firmware:

  • Download mode in Galaxy S II GT I9100 can be entered by pressing Volume down Key, Center button, and holding both simultaneously press the Power Button after which a green robot will be shown indicating the Download Mode has been entered.
  • Open Odin in your computer. Connect your device to the computer with the help of original USB cable and then you will see that the ID : COM Section will turn Yellow.

Note: If ID : COM section doesn’t turn Yellow, you need to check with two things which are mentioned below,

  • Install the USB Drivers in your computer &
  • Go to the Path “Settings > Wireless & Network > USB Settings” and ensure that “Samsung KIES” option is ticked before connecting the phone to the computer.
  • Now, click on the below mentioned options to select the appropriate files.

PDA – CODE_I9100XXLSJ

Phone – MODEM_I9100XXLS6

CSC – CSC_HOME_OXX_I9100OXXLS1

Odin for Galaxy S2

 

  • Once you have selected all the files, you will need to click on “Start” to start the process of firmware update. It will take around 4 -5 minutes for applying the update and once the update process is over, the device will be rebooted automatically.

Options Selected in Odin

  • Once the device restarts, the phone will show up the home screen and all you need to do is to just follow the on screen instructions for starting the device. To check on whether the firmware has been successfully updated or not, head over to the path “Settings > About Phone” where the current firmware will be mentioned as Jellybean 4.1.2. Very soon we will be coming out with an article which will help you root the device.

Note: Just in a rare case if the device doesn’t boot up or show the home screen then remove the battery and reinsert the same to boot the device again in the normal mode.

Do let us know in the comments section below just in case if you face any issues as we will be more than happy to help you out. Congratulations, you have now successfully updated your Galaxy S2 GT I9100 device with the latest firmware update of Jellybean 4.1.2.

After installing, I’ve noticed my internal memory has dropped to 4GB, from just under 12GB before?

    In your previous guides for leaked official updates via odin, always the last step after updating was to restart into in recovery mode for “Wipe data/factory reset” followed by “Wipe Cache partition”. Here you have not included those. Are they necessary still or not?

        Not so sure. Updated via Odin here in Aus and no 50 GB extra Dropbox. Same on 2 seperate phones. Downloaded DropBox app. No email, no 50 GB. Nothing in the setup wizard. Wonder if it is region specific?

    Installed, it’s brilliant, not yet fully tested but it seems working much better than previous 4.0.3. And also received to my already 2gb dropbox account next 48gigs. For those who wonder how, just sign in with your actual account into dropbox on your device first Wizard screen and CLAIM your space by answering an email you’re about to receive

    Hi, Thanks for this, I applied the leaked version, which was made available few days ago, is the current one any different from the leaked version?. Also it works amazingly fine, but I could not see the task manager which is usually native app to manage the memory. Also, is there any demo on how to use new features? tks

          seems like i am having some issues here, i have ICS 4.0.3 build nos IML74kk.xxlpq downloaded to my s2. the green robot comes when i press volume up key, instead of volume down key. when i connect the phone and starts the ODIN it dosent change the color to yellow. I am not able to find the samsung kies in the wifi settings probably it being a ICS and may be it is located somewhere else.

      • Reply Nishanth November 22, 2012 at 3:23 am

        Not sure if you can stop it, but it is a feature that it zooms when you scroll on the side edges of the screen. Seems ok.

      • Reply Steveh3 November 22, 2012 at 8:40 pm

        Think its a feature only does that for me when the scrolling to far right. In the middle is fine. Working like a pc touch pad.

        Are you maybe using the TiltToZoom option (Motion, under settings)?

      • Reply Gmoo November 24, 2012 at 2:38 pm

        Use the right screen edge to zoom in and the left to zoom out. Scroll using the middle of the screen. Takes a bit of getting used to.

        • Gmoo November 24, 2012 at 7:53 pm

          Ignore this advice. Zooms either side. Battery does not drain fast.

      • Reply Shaikh November 30, 2012 at 8:02 pm

        I dont think this as an issue.. its a new feature.. u need to scroll it a little bit on the middle of the screen.. if u scroll it on the left/right of the screen.. it will automaticly zoom in/zoom out..

    This is a fantastic ROM. Thanks for the sneak preview. Do you know why ROM manager will only back up to internal sd card, it no longer asks whether i want to back up to the external sd card like it used to. I have remounted the card in recovery but it doesn’t seem to make any difference.
