Even though it’s not a major update the February 2019 Security Patch is still an important OS improvement available for your Samsung Galaxy J3 2017. The firmware with built number J330LKLU1BSA3 can be useful in different situations and knowing how to install it manually from Odin can help you smartly resolve various problems – for example, by setting up this software you can restore your device back to stock Android OS, or you can use the same flashing procedure for revoking root access and for fixing certain software related issues.
However, the February 2019 Security Patch is here to improve the Android experience provided by your Samsung Galaxy J3. The software isn’t coming with new features or with a new Android functionality but brings essential security patches that can fix important Samsung vulnerabilities. Additionally, the J330LKLU1BSA3 update will add bug fixes and various stability improvements, which combined will smooth up the Samsung UI. Bottom line, we recommend this update opportunity for being able to use the best Android OS that’s officially available for your Samsung Galaxy J3.
As already outlined, being able to manually install the J330LKLU1BSA3 firmware can help you in the future too. In that regard, using Odin for setting up the latest Android platform can help you restore your phone back to its factory state: useful when you want to reset Samsung KNOX, unroot the Android system, relock the bootloader, reinstall the stock recovery image and re-apply bloatware; the same process can also be used as a dedicated troubleshooting solution through which different software related issues can be addressed: recommended when minor problems are experienced – boot loops, lags, hangs, screen freeze, battery drain, heating problems, signal strength issues, total blackouts and so on.
Of course, manually installing the February 2019 Security Patch on your Samsung Galaxy J3 2017 is an official update operation. You won’t risk anything while following the steps from below, so from this perspective you have no reasons to be worried. Odin, the program required, is the official flashing tool developed and offered by Samsung – you won’t have to download and use risky and complex third party apps. You won’t lose your phone’s warranty (that happens only when custom ROMs are being used) and your data should remain secured while Odin is being used.
However, since on your smartphone you might have saved sensible and essential info, we still recommend a backup first. This precaution measure can be quickly and easily completed as you can choose to use Samsung’s cloud storage platforms along with other intuitive backup and restore solutions: sync certain files with your Google Account, use an external storage device or download already tested backup and restore apps from Google Play. While doing that remember to save everything that might be still required afterwards: contacts, call logs, texts, images, videos, audio files, market apps, internet settings, calendar info, saved passwords, EFS folder, IMEI / NVRAM data and so on.
You will have to use a computer, your smartphone and its USB cable. On the computer you will have to download the J330LKLU1BSA3 February 2019 Security patch and to install and run Odin. Afterwards, you will need to connect your Samsung Galaxy J3 2017 with your computer and resume the flashing process from the flashing program – by the way, before doing anything else install the latest drivers of your device on your PC (you can use Samsung KIES in that respect).
On your phone you need to enable the USB Debugging option – this field is located within Developer Options, which can be accessed from general Settings. Note: if you cannot find Developer Options, don’t panic; just go to About Phone and start tapping on Built Number – after 7 or 10 repeated taps the ‘you are a developer’ message should be returned.
Make sure that your phone runs on more than 50% power before starting the update operation. Don’t start the J330LKLU1BSA3 update process if the power is low as then a sudden shut down can happen right while Odin is being used. Unfortunately, unplanned reboots and switch offs can cause severe issues within the Android core system – shortly, if you’re not careful enough you can end up in soft bricking your Android based device.
Of course, follow the steps that are explained below only if you own the 2017 model of the Samsung Galaxy J3. The J330LKLU1BSA3 February 2019 Security Patch is compatible only with this particular Samsung branded smartphone so try not to mess things up.

- It’s safe to close Odin now; also, disconnect your phone from your computer and reboot its system.
- That’s all.
Sometimes during the update operation you can end up in experiencing different problems. Some might be related with the flashing program while some might be caused on your device. In that regard, below we will try to describe the most common issues that might occur while the February 2019 Security patch is being applied on the Samsung Galaxy J3 2017:
Due to various reasons, Odin can stop running or it can get stuck right while you try to apply the steps that are explained above. If that happens, don’t panic as the problems can be easily fixed by following: close Odin on your computer and make sure that there aren’t other associated processes still running in the background (verify that from Task Manager – press the Ctrl+Alt+Del keyboard hotkeys); then, disconnect your phone from your computer by removing the USB cable; afterwards, force restart your Samsung Galaxy J3; next, reinstall your phone’s drivers on your computer; and in the end repeat the flashing steps from the beginning. Now, everything should work without further issues.
In other situations the last reboot that must be initiated in the end can cause a boot loop on your Samsung branded smartphone. So, if you somehow experience this malfunction, try to apply these guidelines: force reboot your Galaxy J3 2017 into recovery mode (you can do it by pressing and holding the Power, Volume Up and Home buttons together until the recovery menu shows up); in recovery you have to initiate a full wipe – you need to make a hard reset and clear app data cache; so select these options: ‘wipe data factory reset’ followed by ‘wipe cache partition’ and by ‘wipe dalvik cache’; when that’s done, return to main menu of recovery and choose to reboot into Android mode. That should fix the boot loop error.
So, there you have it; that’s how you can successfully complete this update operation on your Samsung Galaxy J3 2017. Therefore, you can now use the J330LKLU1BSA3 February 2019 Security Patch on your smartphone which means that you should start testing the new Android UI.
