What to do if Galaxy Note5 won’t install update and showing error code 402

Today’s troubleshooting article answers another set of common #GalaxyNote5 issues that were reported to us. There are many Note5 users who are having trouble installing updates for their device lately so we hope that you’ll find this post helpful.

Problem #1: What to do if Galaxy Note5 won’t install update and showing error code 402

I have a Galaxy Note 5. I noticed my phone has been getting glitchy lately. I normally reset my phone every couple of months but this time I didn’t for many months.  A few days ago I was notified that there was a new update Samsung 23 or something. I’ve downloaded it a number of times but when I install it, I see the Android icon spinning but it only installs up to 26% and then the icon falls over and i receive an Error Code 402. I’ve tried using the Verizon Software Update Assistant as well as the Smart Switch.  Same thing happens. Downloads fine and begins to install but crashes at 26%. I even reset my phone to factory settings and searched for updates and the same thing happens. Please advise.

Solution: Some Verizon users encountered error code 402 in the past so this must be a Verizon -specific code (carrier-provided firmware may has its own set of error codes. Based on previous reports, error code 402  usually happens after a failed update. If updating using official methods did not help, then there may only one way to fix it — flashing stock firmware.

If you haven’t heard of the term flashing before, or if you’re not confident that you can do it yourself, we suggest that you let someone do it for you. Better still, you can bring your phone to your local Verizon or Samsung store and let their representative flash the firmware for you. Your aim is to manually install the original operating system version.

Flashing is basically system modification so it can potentially mess up the software environment of your Note5. You want to be careful when doing it. Use Google to find a good flashing guide for your particular phone model. Keep in mind that using a different firmware version can brick your device.

Problem #2: What to do if Galaxy Note5 memory is damaged or corrupted

Hi Guys. Note 5 goes to an error message when I reboot. DEVICE MEMORY DAMAGED. THE DATA PARTITION HAS BEEN CORRUPTED. YOU NEED TO RESET YOUR DEVICE TO FACTORY DEFAULTS. THIS WILL ERASE ALL YOUR DATA. There is a button below this message for “Reset Device”; when I touch it, phone short-vibrates, but nothing happens. I have also tried power shocking. It simply goes back to the DEVICE DAMAGED message above. Can’t get it to move from there. And if I just let it sit in that mode, it will reboot every 10 minutes or so. Battery is fully charged. Is it salvageable, or is it finished?  Thanks for any help getting this working. Not concerned about saving anything that is stored on the device. PS I don’t know software version so I guessed on that.

Solution: The error suggests that the flash memory where software information are stored has been corrupted causing Android to fail to boot properly. Under normal circumstances, doing a factory reset, which is what the phone is suggesting, helps. If you’ve already tried doing it, or if you are unable to boot the device to Recovery Mode to do a factory reset, your phone is most probably gone. Your phone’s memory is partitioned for a reason and if partitions no longer exists, Android will be unable to find the directory of files it needs to operate normally.

A Samsung Galaxy device’s memory don’t usually get corrupted unless there are system changes that precedes them. Such factors can include a failed system update, rooting, or flashing. To see if you can fix the issue on your end, try to boot your phone to Recovery Mode first. If you are able to boot the device Recovery, then there’s a chance that you may be able to fix the issue.

For reference, these are the steps on how to factory reset your Note5 via Recovery Mode:

1. Turn off your Samsung Galaxy Note 5 completely.
2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
4. Once the Android logo shows, release both the Volume Up and Home buttons.
5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
6. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Problem #3: How to fix Galaxy Note5 Facebook app that keeps crashing

I have a AT&T Samsung Galaxy Note 5. I have downloaded the Facebook app and it will not open, goes to the blue screen and flashes from black back to the blue and will never open. Snapchat does the same thing, opens up and then closes, won’t actually let me reach the log in. I did the clearing of cache partition. It did nothing. I have also tried going through my apps and deleted everything that had been installed except facebook messenger, facebook, snapchat and textnow. Nothing has seemed to help and no software updates are available. Please help me!!

Solution: There had been an issue with Facebook app and other related apps (such as Instagram and Whatsapp). Basically, what’s happening was that some users reported that said apps won’t load and keeps crashing when opened. Facebook already patched the problems so whatever is causing the problem on your end must be caused by something else. We haven’t heard of Snapchat crashing with many devices recently. These two apps must be crashing to some other problems other than coding errors.

To fix the problem, below are the troubleshooting steps that you can try:

Install updates

Be sure that you not only check for Android updates but also for all your apps. If you only get official apps, then make sure that you open Google Play Store app and update your apps from there. If you have apps from non-PLay Store sources, make sure that they are updated and compatible with the current Android operating system version. If you are not sure how to do that, contact the app developers and ask them about it.

Boot to safe mode (only applies if Facebook app is pre-installed)

There’s a chance that one of installed third party apps may be the reason for your problem. To check, boot the phone to safe mode. In this mode, third party apps will be blocked, allowing only pre-installed apps to work. If Facebook works properly in safe mode but not in normal mode, you can bet that one of your apps is to blame.

Restarting your Note5 to safe mode is easy. Here’s how it’s done:

1. Turn the device off.
2. Press and hold the Power key past the model name screen.
3. When “SAMSUNG” appears on the screen, release the Power key.
4. Immediately after releasing the Power key, press and hold the Volume down key.
5. Continue to hold the Volume down key until the device finishes restarting.
6. Safe mode will display in the bottom left corner of the screen.
7. Release the Volume down key when you see Safe Mode.
8. Open Facebook app and see how it works. To know if there’s a difference, use Facebook app for a few hours.

To identify which of your apps is causing the trouble, you should boot the phone back to safe mode and follow these steps:

1. Boot to safe mode.
2. Check for the problem.
3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
4. After you uninstall an app, restart the phone to normal mode and check for the problem.
5. If your Note5 is still problematic, repeat steps 1-4.

Reset app preferences

Some apps may not work properly if a required system app is turned off or disabled. To ensure that all default apps of your Note5 are on, follow the steps below:

1. Open Settings app.
2. Tap Apps.
3. Tap on More settings at the upper right (three-dot icon).
4. Select Reset app preferences.
5. Restart your Note8 and check for the problem.

Factory reset

Ultimately, you want to factory reset your Note5 if all our suggestions above won’t help. There may be a system bug that prevents the app from loading normally. If you haven’t factory reset your phone before, follow the steps above on how to do it.
