    Note: A PC will be required to follow this method.
    Note #2: All user data will be erased. Please backup the files on your phone.

    I will not take responsibility for anything that you choose to do on your device. The method below has been tested and is proven to work. Failure to follow directions may give you unexpected results.

    You have been warned.

    Check in the second post for an easier way to unbrick your phone

    If you're rooted and you're on kernel FL24 or FI27 and you want to install the new Jellybean update (GB27), you're going to have to unroot your phone before doing so or else your phone will be bricked. Follow these simple steps to have your phone unrooted and rocking the new Jellybean update!

    Items required:

    -Desktop Odin v3.0.7
    -Restore file if you're on kernel FL24.*
    -Restore file if you're on kernel FI27.*
    -Restore file if you're on kernel GB27*

    *Make sure you download the file according to the kernel stated on your phone. Using the wrong restore will result in a hard brick.

    If you're kernel version is not listed above, check this website: Rwilco12's Android Repository - Downloads


    1. Download the necessary files above and place them in an easily accessible spot on your computer. (I.E: My Documents, Desktop, etc)
    2. Open Desktop Odin.
    3. Turn your phone off (after making any necessary backups using Titanium Backup or whatever method you choose).
    4. Put your phone into Odin mode. (Hold volume down and the power button until a warning screen shows up)
    5. Plug your phone into your PC. Let any drivers install (if there are any). Desktop Odin should recognize your phone afterwards.
    6. Click "PDA" on Odin and select the kernel file you downloaded that was posted above.

    Before pressing "start", make sure your Odin screen looks similar to this:

    7. Press start. Allow the download to go through and wait for your phone to reboot. Reboot takes up to 5 minutes.

    You should now be on stock FL24 or FI27 or GB27!
    If you were on FI27 rooted and used the FI27 Kernel, you will have to update to FL24 before updating to Jellybean (GB27).

    Below you will find options to backup contacts, messages and help to reinstall third party applications.

    Note: When you sync to your Google Gmail and Exchange ActiveSync

    Un-bricking/Un-Bootlooping your phone using the one-click restore method!

    1)Install Samsung USB/Android drivers (if necessary).

    2)Download the GB27 One-Click self-extractor of choice:

    Kernel GB27:
    SPH-D710_GB27_1014481_Rooted_Nodata.exe (PRESERVE user data - do NOT use if downgrading versions) (md5: 1b7e8f16fc0a2999582bb6dc151d8042)

    Kernel FL24:

    Kernel FI27:

    3)Extract the package
    Double-click on the self-extractor file, specify the directory to extract to (instructions assume C:\)

    4)Start ODIN One-Click file (the files listed above).

    Note #1: On Vista or newer, you may need to right-click on the file and Run as Administrator.

    5)Place phone in ODIN download mode:
    Method #1
    -Power down phone
    -Wait for capacitative button lights to turn off
    -Simultaneously Press and Hold [Power] [VolDn] until confirmation screen appears
    -Press [VolUp] to enter Download mode

    Method #2
    adb reboot download

    Connect USB cable to PC if not already connected. ODIN should show yellow COM port in 2nd column

    Note #2: If you do not see a yellow COM port, you may need to run the ODIN One-Click as Administrator and/or unplug/plugin the USB cable after starting ODIN One-Click.

    6)Start the ODIN flash process
    Press [Start]

    When complete, Status should change to PASS!
    Phone will automatically reboot

    Boot process will be slightly longer than usual during which time you'll see the 4G logo screen.

    -If you are getting random force closes, wipe the cache and dalvik-cache.
    -If you have troubles with Google Play, clear the data from menu->applications->all->market->clear data.

    Can you post a picture of your Odin with the error?

    Are you running odin as administrator?

    That tends to be a problem with odin sometimes.

    Is there a different method if you are using a custom ROM?

    Nope. You can use the same steps.
    I actually used these steps to go to stock from PACman and Cyanogenmod 10.1.
