So you bought a Samsung Galaxy S3 Mini, the mini version of the Galaxy S3 that doesn’t really have anything in common with the latter except in looks, and were excited to get Android 4.1.1 Jelly Bean out of the box. That’s all good, but sadly, by the time Samsung launched the S3 Mini, Google had moved on to Android 4.1.2 and was already planning to launch Android 4.2.
However, Samsung has been moving quite fast these days when it comes to software updates, and while Android 4.2 may still be a distant reality, the Android 4.1.2 update – build number I8190DXALL3 – has begun rolling out for the Galaxy S3 Mini in Indonesia since the last couple of days. In case you missed it, the changes in Android 4.1.2 aren’t anything major, but they still bring some needed performance and stability improvements, and also the ability to expand and collapse the notifications with a one-finger swipe.
While the update will start rolling out in other regions in the world in the coming weeks, for those who don’t want to wait, XDA member faria has taken apart the Indonesian firmware, added the necessary European modem/baseband and European languages, and released a custom version for others to flash and get updated to Android 4.1.2 without waiting for the official update.
That’s not to say that those outside Europe can’t flash this custom firmware, as it will work on every Galaxy S3 Mini out there, as long as you flash it on an unlocked S3 Mini (model number I8190). The firmware doesn’t wipe any data either and can be flashed like an official firmware, meaning your warranty and the dreaded flash counter that shows up on flashing custom software on Samsung phones will not make an appearance.
So if you wish to try out Android 4.1.2 on your Galaxy S3 Mini, simply follow the guide below to find out how it can be flashed on your phone.
The procedure described below is only for the Samsung Galaxy S3 Mini, model number I8190. Do not try it on any other device.
The methods and procedures discussed here are considered risky, so try them out at your own risk, and make sure to read each step carefully before attempting anything. We will not be held responsible if anything goes wrong.
How to Install Android 4.1.2 Firmware on Galaxy S3 Mini
- [Important] While no data will be wiped, it’s recommended to take a backup of all your important apps and other data, as there is a rare chance you might need to manually wipe data in order to make the ROM boot up. Backup your bookmarks, contacts, SMS, APNs (internet settings), etc by taking the help of our Android backup guide. Then, manually copy all the files on the internal storage on the phone to the computer.
- Download and install the software Kies on your computer, which will install the necessary drivers for the phone.
You can also download the drivers directly — download from here: 32 bit (x86) Windows | 64-bit (x64) Windows
- Download the firmware for your country.
Download DXALL3 Firmware
- Using a software like WinRAR, extract the firmware file downloaded in step 3 to a convenient location on your computer, to obtain a file named final.tar.md5 (the file may also show up only as final.tar, which is normal and due to Windows hiding the .md5 part of the file name). This is the actual firmware file that we need to flash on the phone.
- Download Odin. If you are new to this, Odin is a Samsung program used to flash stuff – firmware, kernels, etc. – on Samsung phones. We’ll use Odin to flash the firmware file obtained in step 4.
Download Odin3 v3.04 | Filename: Odin3_v3.04.zip
- Extract the contents of the Odin3_v3.04.zip file to a folder on your computer.
- Now, turn off your phone and wait for it to shut down completely.
- Then, put the phone into download/Odin mode. To do so, press and hold these keys together: Volume Down + Home + Power till the phone turns on and shows a Warning!! screen. Then press Volume Up to enter download mode.
- Open Odin by double-clicking on the Odin3 v3.04.exe file obtained in step 6 after extracting Odin3_v3.04.zip.
- Important! Connect your phone 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, make sure you installed drivers correctly (using Kies or directly) as given in step 2. If it still doesn’t work, try changing to another USB port on the computer and also use the USB ports on the back if you have a desktop PC.
- Click on the PDA button in Odin, then browse to and select the final.tar.md5 file obtained in step 4 above.
- 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 check box is not selected.
- Now, make sure you took a backup as explained in step 1 before continuing, then click the Start button in Odin to start flashing the firmware on your phone. When the flashing is complete and is successful, you’ll get a PASS message (with green background) in the left-most box at the very top of the Odin, and the phone will automatically reboot. When you see the Samsung logo, you can safely unplug the cable.
- What do if Odin gets stuck or doesn’t do anything: If ODIN gets stuck on setup connection or at any stage of this process after you’ve hit the Start button, and doesn’t seem to be doing anything, or if upon completion of the process you get a FAIL message (with red background) in ODIN, do this: disconnect the phone from the PC, close ODIN, remove battery for 4-5 seconds, re-insert it, turn phone on in Download mode again, and do the procedure again from Step 9.
- [Important] What to do if phone doesn’t boot: After you get the PASS message and the phone reboots, the phone 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 phone has already booted, stop reading the guide here, your phone has been updated successfully:
- Boot to recovery mode — for which, first power off phone (by removing battery and reinserting it), wait for 5-6 seconds, and then press and hold Home + Volume Up + Power keys together till the screen turns on, then let them go to boot into recovery. Once you are in recovery mode, use volume keys to move the selection up and down and home/power key to select the option.
- Go to Wipe data/Factory Reset and select it. Select Yes on next screen.
- Then, select reboot system now to reboot the phone, which will now boot properly.
- You can proceed to restoring your data if you had to wipe it in step 14. If you run into any roadblocks while flashing the firmware, let us know and we’ll help you out.
