Another Official Jelly Bean Firmware Leaked for Galaxy S3 – XXDLH4 [Android 4.1]

Advertisement

Yesterday was a very happy day for owners of the Galaxy S3, as the first official Jelly Bean Android 4.1 firmware was leaked for it, and while not it wasn’t too final or stable a build, it is at least a reminder that Samsung is working hard and fast at bringing out Jelly Bean officially. Now, another firmware has leaked for it, having the firmware version XXDLH4.

Again, we have a guide ready which you can follow to flash the latest leaked firmware on your Galaxy S3. This time however, the firmware needs to be flashed from ClockworkMod recovery instead of the usual Odin method.

Keep in mind that this is a leaked firmware and quite an early build, so it might have some serious issues or bugs, which might make it unstable for every day use. But you can still try it out, as you can always flash back to an Android 4.0 firmware later if needed.

So, continue reading to find out how you can flash the leaked XXDLH4 Jelly Bean firmware on the Galaxy S3.

Compatibility

This guide to install Android 4.1 Jelly Bean firmware is compatible only and only with the international Galaxy S3, model number i9300. It’s not compatible with the US variants or any other device. Check your device’s model number in: Settings » About phone.

Warning!

The methods and procedures discussed here are considered risky and you should not attempt anything if you don’t know completely what it is. If any damage occurs to your device, we won’t be held liable.

  1. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you. This is to ensure you don’t lose data if anything goes wrong.
    NOTE: Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
  2. Make sure you have ClockworkMod recovery installed. If not, use this guide to install it.
  3. Download the following files:
    1. XXBLG8 ICS Firmware
      Filename: Samsung-Updates.com-GT-I9300_BTU_1_20120806161432_al03it6wa2.zip
    2. XXDLH4 Jelly Bean Firmware
      Filename: Samsung-Updates.com-GT-I9300-BTU-JB_4_1_1-I9300XXBLH4-OTA-INTERNAL.zip
  4. Copy both the zip files downloaded in step 3 to the internal SD card on your phone.
  5. Now, boot into ClockworkMod recovery. To do that, turn off your phone. Then, hold down Volume Up, Home and then the Power buttons together until the screen turns on, then let them go. The phone will boot into ClockworkMod recovery in a few seconds.
    In recovery, use the volume buttons to scroll up/down and the home button to select an option.
  6. Perform a Nandroid Backup of your existing ROM, so that you can restore it from recovery if something does not work out with the Jelly Bean ROM. To perform a backup, select Backup and Restore –> On the next screen, select Backup again. Go back to main recovery menu after backup is complete.
  7. Select install zip from sdcard, then select choose zip from sdcard. Scroll to the Samsung-Updates.com-GT-I9300_BTU_1_20120806161432_al03it6wa2.zip file on the SD card and select it. Confirm installation by selecting Yes on the next screen to first install the XXBLG8 ICS firmware.
  8. After installation is complete, select go back then select reboot system now to reboot the phone. Wait for the phone to boot up. After the phone boots up, turn it off and boot into recovery again (using the procedure explained in step 5).
    NOTE: If your phone doesn’t boot up after about 5 minutes, simply remove the battery on the phone, re-insert it, then boot into recovery. Then, wipe data by selecting wipe data/factory reset. You only need to wipe data if the phone doesn’t boot after flashing the XXBLG8 ICS firmware.
  9. Now, select install zip from sdcard again, then select choose zip from sdcard. Scroll to the Samsung-Updates.com-GT-I9300-BTU-JB_4_1_1-I9300XXDLH4-OTA-INTERNAL.zip file on the SD card and select it. Confirm installation by selecting Yes on the next screen to install the Jelly Bean firmware.
  10. After installation is complete, select go back then select reboot system now to reboot the phone. Wait for the phone to boot up into the Jelly Bean Android 4.1 XXDLH4 firmware.
    NOTE: To go back to your previous ROM, boot into recovery (using the procedure explained in step 5), select backup and restore then restore your previous ROM by selecting it from the list.

The leaked XXDLH4 Jelly Bean firmware is now installed on your Galaxy S3. Try it out and let us know if you encounter problems while flashing and we’ll try to help you out. Also do let us know how it works!
