Firmware: Android 4.1 Jelly Bean Update for Samsung Galaxy Chat [Guide]

Samsung has finally decided to turn their attention to the low-end crop of Galaxy devices – starting today, the official Android 4.1.2 Jelly Bean update has begun rolling out for the Galaxy Chat in Spain, bringing an important update to the chat-centric smartphone.

The Galaxy Chat is the first low-end device by the company that has received a major OS upgrade, at least to my knowledge, which is a great thing and is something other manufacturers would do well to learn from. There’s no official changelog as is often the case with Samsung’s updates, but we can expect the usual Jelly Bean features to make an appearance – faster performance and smoother interface, expandable and actionable notifications, Google Now, better keyboard, resizable widgets, and more.

The update is currently rolling out over the air and via Kies in Spain for unlocked Galaxy Chat, but those that don’t wish to wait and would like to flash the update manually (especially if they are on a custom ROM), we have a step-by-step guide below to help with that.

It can be installed by those not in Spain and those on custom ROMs as well, but remember that if you do so, you might need to wipe all data on the device in order to make it boot after the update. If you aren’t comfortable with that, you should wait for the update to roll out in your country.

Now let’s take a look at how the official Android 4.1.2 firmware can be installed on the Galaxy Chat.


The procedure described below is only for the Samsung Galaxy Chat, model number B5330. 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 Jelly Bean on Galaxy Chat

  1. [Important] You might need to wipe the data on the phone to make the firmware boot up properly, especially if the firmware is flashed over a custom ROM or from a country other than Spain. Hence, to be sure you do not lose any data, backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you. The SD card contents are always safe, so there is no need to back up those. Only backup apps and personal data.
  2. Download and install the software Kies on your computer, which will install the necessary drivers for the phone.
    Download Kies
    You can also download the drivers directly — download from here: 32 bit (x86) Windows | 64-bit (x64) Windows
  3. Download the firmware.
    Download Link Alternate Link (Recommended)
  4. Extract the file downloaded in step 3 on the computer to obtain a file named B5330XXUBMC2_B5330OXABMC2_B5330XXUBMC2_HOME.tar.md5 (the file name may end at .tar, which is normal). This is the actual firmware file that we need to flash on the phone.
  5. 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:
  6. Extract the contents of the file to a folder on your computer.
  7. Now, turn off your phone and wait for it to shut down completely.
  8. Then, put the phone into download mode. To do so, press and hold these keys together: Volume Down + OK button + Power till the phone turns on and shows a Warning!! screen. Then press Volume Up to enter download mode.
  9. Open Odin by double-clicking on the Odin3 v3.04.exe file obtained in step 6 after extracting
  10. 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.
  11. Click on the PDA button in Odin, then browse to and select the B5330XXUBMC2_B5330OXABMC2_B5330XXUBMC2_HOME.tar.md5 file that you extracted in 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 check box is not selected.
  13. 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.
  14. [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:
    1. 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.
    2. Go to Wipe data/Factory Reset and select it. Select Yes on next screen.
    3. Then, select reboot system now to reboot the phone, which will now boot properly.
  15. If you run into any roadblocks while flashing the firmware, let us know and we’ll help you out.
