If you thought that Samsung is focusing in updating only its high end devices, well then you should know that a few days ago, in Spain, the official Jelly Bean 4.1.2 OTA firmware has been rolled out for the Galaxy Chat. This smartphone is the first low-end handset to receive the Jelly Bean touch, so it’s good to see that Samsung had decided to please its entry level customers. Now, if you need to manually update your Galaxy Chat to official Jelly Bean 4.1.2 then you will have to complete the present step by step guide which will easily take you through the flashing procedure.
Remember that the Android 4.1.2 software is OTA available only in Spain, at least for now, but don’t worry as the update will be released on other markets soon. Anyway, if you don’t want to wait no more, then this tutorial will be perfect for you. A manual update operation must be performed by those who haven’t received the OTA firmware until now, or by those who have rooted or installed a custom ROM on their Samsung Galaxy Chat (in that case you will not be able to flash the Jelly Bean OS by using KIES or over the air).
So, here what you should know so far: we are dealing with the stock / official Jelly Bean update that can be applied on the Galaxy Chat; the ROM has been released in Spain but it can be installed on all the unlocked Chat devices; if your phone is rooted or updated with a custom ROM you cannot OTA flash the software; this tutorial will show you how to manually update your Galaxy Chat to official Android 4.1.2, so the warranty of your smartphone will not be voided by completing the below steps.
Furthermore, your phone doesn’t have to be rooted or installed with a custom recovery image for being able to flash the stock Jelly Bean OS into its system. As you will see, for updating your Galaxy Chat we will use Odin, this being the only tool that must be installed on your computer. Anyway, another aspect related to the present operation is the warranty; as already mentioned the same will not get lost, but if you have somehow previously void it, then now you will be able to restore it back because the system will be relocked and the default settings reinstalled.
This means that if your Chat is rooted, after updating to official Android 4.1.2, the root access will be revoked and the bootloader relocked. Don’t worry though as you will be able to easily re-root your device; there are many root tutorials that can be used for unchaining the Jelly Bean system (you can anytime learn how to apply a general root procedure that works on almost all the Android based handsets, or you can apply a one click root method suitable only for the Samsung branded devices).
Now, if you have decided to complete this tutorial, then first backup the Galaxy Chat data. In some cases, for resolving some problems, or for making things work properly, a wipe of the system is being required. Because of the same it is more than recommended to save your contacts list, text messages, call logs, EFS, market apps and everything else before going any further. More, if possible you can also make a Nandroid backup.
Finally, here is what you need to do and to prepare before starting to update your Samsung Galaxy Chat to official Jelly Bean OS: a Windows running computer must be near you as you will need to use the same; it will be a good idea to charge your smartphone (especially if you notice that there is less than 60% power left) and to remove the security programs from its system (and from the computer) because these programs are usually interfering with the flashing process; enable the USB debugging option on your phone.
Do apply this step by step guide only for the unlocked Samsung Galaxy Chat; the steps from below are compatible only with the mentioned handset. If you try to complete this tutorial on a different smartphone, then you will risk in bricking your Android based device.
Update Galaxy Chat to official Android 4.1.2 Jelly Bean Firmware
- The Galaxy Chat drivers must be installed on your computer (if they are, skip this step); so download and install Samsung KIES.
- Then, as mentioned, Odin will have to be used; download and install Odin on the computer.
- Finally, download the update file from here, or from here; then extract it on the desktop.
- On your computer open Odin.
- Boot your phone into download mode.
- For doing that first turn it off; the press the Power, Volume Down and OK buttons at the same time.
- Connect the Chat with the computer.
- Now, on Odin the “added” message should be displayed; also the ID:COM section should be yellow or blue.
- If not, reinstall the drivers, restart Odin and repeat the steps from above.
- On Odin select “PDA” and pick the update file.
- Don’t make any other changes on Odin; the “Re-partition” option should be unchecked.
- Click on “Start”.
- The process will end when the “pass” message will be displayed.
- You can unplug the USB cable and reboot your device as we are done.
- If somehow Odin gets stuck while you are trying to apply the steps from above, you will have to: close Odin, unplug the USB cord, force restart the Galaxy Chat, reinstall the drivers and repeat the flashing procedure from the beginning.
- Then, if in the end, instead of a normal boot you will get a boot loop, here is what you need to do: reboot the smartphone by pressing on Power, Volume Up and OK buttons until recovery mode is being displayed; select “wipe data factory reset” and “wipe cache partition”; select “+++go back+++” and “reboot system now”.
