Step-by-step guide to troubleshooting Galaxy J5 that’s stuck on boot screen

First off, this troubleshooting guide is for our readers who encountered this problem without attempting to modify the firmware of the phone. You should know that rooting and flashing custom ROM may also result to this kind of problem so this troubleshooting guide may not work in such case. If, however, you didn’t try to modify the firmware, then continue reading as the procedures in this post may be able to help you.

Before we move on to the steps, here’s one of the messages we received from our readers who have encountered this issue…

Problem: Hi guys! I have the Galaxy J5 phone and recently, there was an update that was installed after the download. I was still able to use my phone for a few days after the update but then it started to become really slow until one day it rebooted on its own a couple of times. Then, it got stuck on the black screen and won’t move on to the home screen. The black screen that comes after the logo. Can you help me fix this problem?

Troubleshooting: Now, it’s time to go to the steps or procedures that might bring your phone back to life…

Step 1: Attempt to boot your phone in safe mode

Let’s immediately try to isolate the problem. As you know, there are times when third-party apps crash and affect the normal operation of the firmware. When this happens, the phone may be stuck during the boot up process and may not continue until you do something about it. This is the first thing I want you to do; it’s safe and effective. Safe in a sense that it doesn’t actually do something on your device except temporarily disable all third-party apps. So, if the cause of the problem is a third-party app, then your phone should be able to boot up in this mode without a problem. This is how you do it:

1. Turn your Galaxy J5 off.
2. Press and hold the Power key past the screen with the device name.
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’.

Assuming your phone can boot up successfully in this mode, then the next step is applicable, otherwise, skip to step 3.

Step 2: Find, reset, update and / or uninstall the apps that cause the problem

If your Galaxy J5 can successfully boot up in Safe mode, then you can rest assured your phone and its hardware is fine. The problem could be in one or some of the apps you installed. In this case, you just have to find the app that’s causing the problem. If you’ve installed an app prior to the problem, then you must start your troubleshooting from there. Once you have a suspect, try to reset it first by clearing its cache and data:

1. From any Home screen, tap the Apps icon.
2. Tap Settings.
3. Tap Applications.
4. Tap Application manager.
5. Tap the desired application in the default list or tap MORE > Show system apps to display pre-installed apps.
6. Tap Storage.
7. Tap Clear data and then tap OK.
8. Tap Clear cache.

After this, try to see if there are apps that need to be updated and update them if necessary…

1. From any Home screen, tap the Apps icon.
2. Tap Play Store.
3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu key, tap Settings, and then tap Auto-update apps to select the check box.
4. Choose one of the following options:
   1. Tap Update [xx] to update all applications with updates available.
   2. Tap an individual application and then tap Update to update a single application.

After this, try to reboot your phone in normal mode to see if it can successfully do that. If still no, then boot your phone  back into safe mode and uninstall the app you reset a while ago.

1. From any Home screen, tap the Apps icon.
2. Tap Settings.
3. Tap Applications.
4. Tap Application manager.
5. Tap the desired application
6. Tap Uninstall.
7. Tap Uninstall again to confirm.

It’s time to boot your phone back in normal mode and assuming the problem is as simple as that, this time it might be successful and you can continue using your phone.

Step 3: Soft reset your phone

You do this if the phone cannot continue booting up in safe mode. All you have to do is remove the back cover and pull the battery out while the device is still powered on. This will refresh your phone’s memory and if the problem is caused by a glitch, it might boot up normally after this. To continue, while the battery is out, press and hold the Power key for a minute. After which, place the battery back in, secure it with the back cover and then try to turn the phone on. If the phone still refuses to boot up normally, then move on to the next step.

Step 4: Attempt to boot your phone in Recovery mode

After doing the previous steps and your phone is still not capable of booting up successfully, then it might be an issue with the firmware already. The thing is, Android has a fail-safe wherein the firmware can still boot up in an environment that may allow users to do something about it. If the phone has a problem with the firmware, it may still be able to boot up in Android system recovery or Recovery mode.

If successful, then try wiping the cache partition and if that fails, proceed with the reset. Here are the steps on how to boot your Galaxy J5 in Recovery mode and wipe the cache partition:

1. Turn off the device.
2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
3. When the device logo screen displays, release only the Power key
4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
6. Press the Power key to select.
7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
9. Press the Power key to restart the device.

And this is how you reset your phone…

1. Turn off the device.
2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
3. When the device logo screen displays, release only the Power key
4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
6. Press Power button to select.
7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
8. Press Power button to select and start the master reset.
9. When the master reset is complete, ‘Reboot system now’ is highlighted.
10. Press the Power key to restart the device.

I hope this helps.
