Android 4.1.2 Jelly Bean has been pushed out for the T-Mobile Galaxy Note 2 smartphone and now you can flash it yourself using this manual tutorial. Read the entire post and make sure that you won’t skip any steps that I have listed below.
The Android 4.1.2 OTA Update brought LTE Network connectivity support for the TMO Galaxy Note 2 and it has the build number T889UVBMB4. You will get all the Jelly Bean 4.1.2 and TouchWiz Nature UX features and functions. More info about this update and what does it bring can be found here.
This is a guide for those T-Mobile Galaxy Note 2 users who want to manually update their phones. Also, this guide can be used if you’re using a custom ROM but that will need you to factory reset your device which means that you will lose installed apps, SMS, Call Logs and you will then have to re-configure the entire tutorial once again. It is recommended for you to update your device only if your TMO Note 2 is running a previous build of Android 4.0.x firmware and not an advanced Android 4.1/ 4.2 custom ROM.
Before installing this new Android 4.1.2 Jelly Bean UVBMB4 firmware update for the T-Mobile Galaxy Note 2, you need to take a look at the guidelines that I’ve listed below:
- use this tutorial only with the T-Mobile Galaxy Note 2 smartphone with the model number SGH-T889. You can find the model number in the About Tablet menu. Don’t try to update any other Android version using this guide.
- Make sure that your computer has the Samsung USB drivers installed on it. Without these you won’t be able to flash the new update.
- Disable all the antivirus application from running on your PC, as these are usually interfering with the updating tools such as Odin.
- Enable the USB Debugging option from the Developer Options menu. After you install the new Jelly Bean OS you will see that these options will not be displayed and you have to open the Settings menu, then scroll down and open ‘About tablet’ menu. After that you have to press 7 times the ‘Build Number’ section, which will eventually enable the Developer Options menu.
- Make sure to backup your data in case your tablet is rooted or running a different Android OS than the stock one.
- Make sure that your tablet’s battery power charging level is over 50%. This will prevent the device from switching off during the updating process.
- Read the entire tutorial and don’t skip any steps I’ve listed.
- We cannot be blamed in case you lose any important data nor in case you brick the tablet. Make sure to ask for any extra help in comments in case you don’t understand some of the instructions.
These were all the guidelines that you had to go over before installing the new firmware update. Now that you know all of the above I think that you can begin the installation process.
How to update T-Mobile Galaxy Note 2 to official Android 4.1.2 Jelly Bean UVBMB4 firmware:
- Download the ROM zip file from HERE. Extract the contents of this zip and you’ll get a ‘.tar.md5′ or ‘.tar’ only file. Save it on your PC and don’t extract it any further than that.
- Download Odin 3.04 from HERE. Extract the contents and save the files on your computer.,
- Power off the smartphone now. Boot it into Download Mode by pressing and holding Volume Down, Home and Power buttons at the same time. When the display powers on you can release the buttons and you will see an alert message, press Volume Up to confirm Download Mode. Get to the next step now.
- Launch Odin executable on your computer.
- Connect your TMobile Galaxy Note 2 to your PC using the USB Data Cable. When ODIN display the ‘added!!’ text then you can continue to the next step.
- Click the buttons that says ‘PDA’ from ODIN’s menu. Now you should load the ‘.tar.md5′ file you obtained in step 1. Load it into ODIN. Don’t change any other default ODIN settings.
- Click the START button when you’re ready to start the updating process of your Note 2. When the Update is complete you will see that ODIN shows the PASS alert and you can disconnect the device from PC.
- Now your device will boot into normal mode and you can start testing the firmware update.
NOTE: If ODIN displays the FAIL message, or it freezes and it doesn’t complete the update, then you have to disconnect the device from PC and then close ODIN. Remove the phone’s battery and re-insert it after 5 seconds have passed. Repeat the entire tutorial starting with step 3 and this time you have to make sure that you don’t skip any instructions.
NOTE 2: If Odin says PASS but the phone doesn’t go past the Samsung Galaxy Note 2 boot animation logo, then you will have to ‘factory reset’ the phone from the RECOVERY mode. This means that you will lose all the installed apps, SMS and all the other data from the /system partition. Here’s how to do it:
- remove the phone’s battery and then re-insert it back to its place after 5 seconds have passed.
- Next, the phone has to stay powered OFF and you have to press these buttons all at the same time: Volume Up, Home and Power. Let go off them when the RECOVERY MODE loads.
- Select ‘wipe data/ factory reset’ option and then confirm this process.
- Select ‘reboot system now’ option and then wait until the device boots into normal mode.
These were all the steps that you had to take in order to make sure that you complete the Android 4.1.2 Jelly Bean official firmware update for your Galaxy Note 2 on T-Mobile network.
