Problem 1: Galaxy Note 5 shuts down on its own, keeps boot looping
Help. My phone goes into bootloop mode several times a day! It will be on and working fine, then all of a sudden will flash to the start up screen like it is rebooting without ME restarting it, like it has a mind of its own! I tried to fix the problem by putting it in safe mode and wiping the cache, but it doesn’t usually help. Sometimes it will come back on all on its own, but I usually have to wait for the battery to drain then only after recharging will I have success with it coming back on! It is very frustrating having this happen several times a day, almost everyday (although some days I have no prob whatsoever!). I just want to be able to have a reliable phone.. Plz help! Thank You! — Deena
Solution: Hi Deena. An issue like this can be caused by a few things. Let’s discuss each of them briefly.
Third party apps
Wiping the cache and restarting your phone to safe mode are two of the basic troubleshooting steps that you can do in this situation. As you probably have known already, safe mode is only recommended if you think that a third party app is causing a problem. It is not a solution in itself because it won’t eliminate the problem. You need to allow the phone to run while it’s on safe mode for, say, 24 hours in order to know if a third party app is to blame. Only then can you do something about the issue (by uninstalling apps). If you restart the phone to safe mode for just a minute and hope that it fixes the problem, that’s an incorrect approach.
Battery may need recalibration
In some cases that show the same symptom, battery recalibration is a good fix. Here’s how to do that:
- Drain the battery completely. This means using your device until it powers down by its own and the battery level reads 0%.
- Charge the phone until it reaches 100%. Be sure to use original charging equipment for your iPhone and let it charge up completely. Do not unplug your device for at least two more hours and also don’t use it while charging.
- After the elapsed time, unplug your device.
- Perform a warm restart by holding the Power and Home buttons simultaneously until the Apple logo appears.
- Use your phone until it completely ran out of power again.
- Repeat steps 1-5.
If there’s an important step that must be done in this case, it is the factory reset. In fact, you can do it right away if you wish. Because a factory reset device runs a known working software version and all additional content like apps, files, etc., are removed from the system, it’s an effective way to quickly determine if the problem is being caused by software glitch or by a bad hardware. Like in safe mode, make sure to allow your phone to run for at least 24 hours after you’ve factory reset it so you’ll know the difference. To eliminate external interference, make sure not to install anything during the observation period. If the phone won’t restart on its own during this time, you know an app is most probably to blame. However, if the issue remains, the cause must be a glitch in the firmware (if you’re using a custom ROM) or a hardware malfunction, like a bad battery, power management IC, etc.
To factory reset your Note 5, follow these steps:
- Turn off your Samsung Galaxy Note 5 completely.
- Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
- Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
- Once the Android logo shows, release both the Volume Up and Home buttons.
- 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.
- Use the Volume Down key to highlight the option Yes — delete all user data and press the Power key to select it.
- 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.
- The reboot may take a little longer to complete but don’t worry and wait for the device to become active.
Reflash the bootloader
If you happen to root your device, consider unrooting it and see how it works afterwards.
Also, if your phone is running a custom ROM or unofficial Android firmware, be sure to reflash the bootloader and firmware back to stock.
Since most guides online only provide steps how to reflash a firmware, we should give you the steps on how to reflash the bootloader instead. After flashing the bootloader, you can then reflash the firmware. The steps below are for demonstration purposes only. Be sure to consult other guides to have an accurate set of instructions for your particular phone model.
- Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
- Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
- Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
- Proceed with the rest of the flashing procedure using the Odin program.
- In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
- Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
- Restart the phone once the procedure is finished.
Contact Samsung/have phone repaired
If everything else fails, you can assume that bad hardware must be to blame. Let Samsung or an independent service center fix the issue for you.
Problem 2: Galaxy Note 5 screen won’t turn on
Hi. I don’t know what is going on with my Samsung Note 5. It was working fine earlier tonight and then I plugged it in as the battery was running low.Â I am continuing to receive notifications – I can hear the vibration and see the blue light flashing. The two buttons on the display also light up, however the rest of the display is black.Â When I do a soft reset, the Samsung graphic does not show up on the display. I have tried this a couple of times.Â Please advise.Â I am unsure which operating system is on the phone. — Lex
Solution: Hi Lex. Your phone’s screen may have malfunctioned, or may have even died for some reason. To see if it’s being caused by a software issue, try to see if you can boot the device to alternate modes and do follow up troubleshooting. Here’s how:
Boot in Recovery mode:
- Turn off the phone. This is important. You won’t be able to boot to Recovery unless the phone is turned off first. If you can’t turn it off normally, wait until the phone has drained the battery completely and shuts itself down.
- Charge the phone for at least 30 minutes.
- Press and then hold the Home and Volume UP keys, then press and hold the Power key.
- When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
- When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
- You can either wipe the cache partition or do a factory reset when in this mode.
Boot in Download Mode:
- Turn off the phone. This is important. You won’t be able to boot to Odin mode unless the phone is turned off first. If you can’t turn it off normally, wait until the phone has drained the battery completely and shuts itself down.
- Charge the phone for at least 30 minutes.
- Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
- When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
- Wait until the Download screen appears.
- If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
- Use Google to look for a guide on how to do it.
If the screen stays black after attempting the procedures above, that means it has gone bad. Let Samsung check the hardware so repair can be done.
