Leaked XXDLI1 Android 4.1.1 Jelly Bean Firmware for Galaxy S3 I9300

It seems like Samsung leaks a new Android 4.1 Jelly Bean every week now. It seems like a brand new leak has been released several hours ago and its version is XXDLI1 and it comes with several bug fixes for the previous XXDLH9 Jelly bean 4.1 firmware. Use the instructions that I have listed in this article and you will learn how to correctly flash this leaked update for your Galaxy S3.

It is easy to update your phone to this new firmware and you should make sure that before you start installing it, you will first read the info listed under ‘preparation guide’ to learn what steps you have to take so that you’ll make sure that the smartphone and your computer devices are correctly configured, so that you’ll manage to install all files at the first attempt. This guide will teach how to manually update the firmware of your Galaxy S3 to the latest leaked Jelly Bean 4.1 version, XXDLI1 build.

I’ve found this build on the XDA forums where AdamLange, a Senior Member created a working zip for the international variant of Galaxy S3 model number I9300.

Read the instructions below and only after you’re sure that all these pre-requirements have been, only then you can move to the next part of this guide. Here’s what you need to know:

  • Install the firmware only on the Samsung Galaxy S3 model number I9300. Do not attempt to flash I9300XXDLI1 on other smartphones as it won’t work. TO check the version of your phone, open Settings and then check the info under the ‘About device’ menu.
  • Move all the important files from your phone’s internal sdcard and to your computer via USB cable. The installing of this new firmware update might delete all the files that are currently stored on your phone and on its internal / external sdcard. After the update is complete you can restore all files back to your smartphone.
  • Sync your Phone Contacts with your Gmail account and prevent any SIM / phone numbers from being lost.
  • Make sure that your computer is running the latest Samsung USB drivers. Use the following links and download the drivers for your smartphone: Samsung USB drivers for Windows X86 – 32bit || Samsung USB Drivers for Windows X64 – 64bit. Alternatively, you can use Samsung KIES to install them, but remember to disable and uninstall KIES before moving to the tutorial guide.
  • Go to your phone’s Development settings and enable the ‘USB debugging’ option. This is a mandatory step that you need to take.
  • Disable all antivirus and security applications running on your PC.
  • Charge the phone’s battery so that it won’t switch OFF while you’re flashing the new firmware files.
  • Note that you shouldn’t blame us in case your device gets bricked or in case you lose important files in the process.
  • Install this new firmware will revoke any root access that your phone might have right now.
  • Note that your device should be running a custom recovery image.
  • You will first need to install a different ROM, the XXBLG8 ICS 4.0 and only after that you will be able to flash this new XXDLI1 firmware. All the info can be found in the tutorial below.
  • If you cannot complete the installation, then you should ask for help at the end of this article by posting a detailed comment telling us exactly the steps you took and where you got stuck while trying to flash XXDLI1 Jelly Bean 4.1 firmware files.

I think that these are all the general instructions that you had to follow and now you should proceed to the ‘how-to’ guide to learn how to properly flash the latest leaked Jelly Bean 4.1 firmware for your Samsung Galaxy S3.

How to update Galaxy S3 I9300 to XXDLI1 4.1 leaked firmware:

  1. First, download the XXBLG8 ICS 4.0 firmware zip file from HERE. Save the file on your PC desktop screen. DO NOT UNZIP the contents of the zip file.
  2. Second, download the XXDLI1 Jelly Bean 4.1 firmware zip file from HERE or from HERE. Proceed and save the file on your PC without extracting its files.
  3. Connect your smartphone to your PC and then move both zip files on its internal SDcard. Disconnect the phone from computer after the files are transferred successfully.
  4. Power off the phone and then boot it into Download Mode. To boot this mode you will have to press and hold ‘volume up’ + ‘home’ + ‘power’ buttons and when the display lights up, you can release the buttons as the ClockworkMod Recovery screen will load.
  5. When you’re at the main recovery menu you should select ‘backup and restore’ and then use the ‘backup’ function to create a full Nandroid backup of the currently installed ROM. In case you already made such backup, then you should skip this step. When the backup is complete you should return to the main recovery menu.
  6. Now, select ‘install zip from sdcard’ and from the next menu you should select ‘choose zip from sdcard’. Now select the ‘XXBLG8’ ICS zip file and install it. It is the file you downloaded at step 1. After this ICS firmware was successfully installed you should return to the main recovery screen.
  7. When the ICS build firmware is installed you should select ‘reboot system now’ and wait for the I9300 device to complete the reboot. After that you should power it OFF and then boot into CWM Recovery menu again. Use the step 4 to boot into ClockworkMod Recovery once again.
  8. Select again ‘install zip from sdcard’ and then select ‘choose zip from sdcard’. This time you will have to install the ‘XXDLI1’ JB 4.1.1 OTA zip file. It should be the one that you downloaded at step 2 and then moved on your device’s internal sdcard. Confirm its installation.
  9. Return to the main recovery menu and after that select ‘reboot system now’ and then wait until the phone boots successfully into normal mode.
  10. Note that after each time you’ve installed one of the two ROMs, you should wait at least 5 minutes for the first boot process to load. It will boot normally and you should take control over your phone by entering your Google Account details.

That should do it, now your device should be running the latest leaked XXDLI1 Android 4.1.1 Jelly Bean firmware. In case your device gets stuck after installing one of the updates, then you should re-enter CWM recovery mode and then you will be forced to apply the ‘wipe data/ factory reset’ option and after you will be forced to install again the first XXBLG8 ROM and then flash the XXDLI1 firmware.

If you cannot complete the installation of this leaked Jelly Bean 4.1.1 firmware, then you should ask for help in comments. Please post detailed info on which steps you took and where you got stuck during the firmware update. This release works only with the I9300 variant of International Galaxy S3 smartphone.
