How To Install DDBLH3 Android 4.0 Firmware on Galaxy Tab 2 7.0 P3100

  1. Backup your apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you. Be sure to make a backup, so that if anything goes wrong with the flash, you can restore your data. Your SD card files will remain intact though, so no need to backup those.
  2. It’s important you’ve the proper drivers for the tablet installed. If you have installed Samsung’s Kies software, and have connected your tablet atleast once with Kies, you already have the drivers. If not, then download and install Kies and connect your device at least once then disconnect and reboot your device and PC.
    Download Kies
  3. Download the DDBLH3  firmware.
    Download Link  |  Alternate Link
    Filename:  P3100DDBLH3_P3100ODDBLH1_INU.zip | 758.8 MB
  4. Extract the downloaded zip file once to get a file named P3100DDBLH3_P3100ODDBLH1_INU_HOME.tar.md5 (you might see the file name end with .tar instead of .md5 as the file extension is usually hidden, so it’s normal).
  5. Download Odin, which will be used to flash the firmware on your tablet.
    Download Odin3 v3.04   |  Filename: Odin3_v3.04.zip
  6. Extract the contents of the Odin3_v3.04.zip file to a folder on your computer.
  7. Disconnect your Tablet if it’s connected to PC, then switch it off.
  8. Now, put the Galaxy Tablet 2 7.0 in Download Mode — press and hold these keys together: Volume Up + Power (the volume up key is the volume key on the right).
    A Warning! screen will come up; press Volume Up key to continue to enter Download Mode.
  9. Open Odin by double-clicking on the Odin3 v3.04.exe file obtained in step 6 after extracting Odin3_v3.04.zip.
  10. Connect your tablet to PC now. You should get the message “Added!” under Odin’s message box in the bottom left.If you don’t get this message, then probably there is a problem with drivers. Make sure you’ve proper drivers installed (check step 2). Also, uninstall Kies from the Control Panel as well (this will leave the drivers on the computer but remove Kies which can interfere with the procedure).
  11. In ODIN, Click on PDA and select P3100DDBLH3_P3100ODDBLH1_INU_HOME.tar.md5 (from step 4).
  12. Important! Do not make any other changes in Odin except selecting the required files as given in step 11. Leave all other options as they are. Make sure Re-partition option is not selected and is unchecked.
  13. Now, hit the START button to start flashing the firmware. When the flashing is complete, your tablet will automatically reboot — and when you see the Samsung logo, you can safely unplug the cable. Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of the Odin.
    What to do if Odin gets stuck: If ODIN gets stuck and doesn’t seem to be doing anything, or you get a FAIL message (with red background) in ODIN, disconnect the tablet from the PC, close ODIN, then press and hold Volume Up + Power keys till the device reboots and shows the Warning! screen. Here, press Volume Up key to continue to enter Download Mode, then repeat the procedure again from Step 9.
  14. [Important] After you get the PASS message and the tablet reboots, it might get stuck at the booting animation. If that happens, perform the following steps to make it boot. Remember that these steps will wipe your personal data like contacts, apps, messages, etc. If your tablet has already booted, skip these steps, your tablet has been updated successfully:
    1. Boot to recovery mode — for which, press and hold Volume Down + Power keys (Volume Down button is the one next to the power button i.e the left volume key) together till the tablet reboots, then let go of the power button but keep holding down the Volume Down button for a few more seconds to boot into recovery. Once you are in recovery mode, use volume keys to move the selection up and down and power key to select the option.
    2. Go to Wipe data/Factory Reset and select it. Select Yes on next screen.
    3. Then, select reboot system now to reboot the tablet, which will now boot properly.
