Problem #1: How to fix dm-verity verification failed on Galaxy Note 5

Someone else tried and messed up the regular finger print entry so the phone asks me to enter the backup password. I tried a password which I thought was still right but I forgot that I have changed it. Then my friend wiped the data partition thinking it will ask for finger print but little did he know he would encounter a boot loop where the phone won’t boot beyond the start screen. We also thought factory reset would help but it is still stuck in boot loop. In the recovery page shows a problem that says,

“dm-verity verification failed…

Need to check DRK first…”

I just can’t get past this recovery page, down load mode, and the boot loop screen. Eventhough I remember the back up password now there is no way I can enter or use it now. And both my WiFi and mobile data are turned off.

Please help. — Mintesinot

Solution: Hi Mintesinot. “dm-verity verification failed” error is an indication that there were attempts to modify the firmware and were deemed a security threat, thus the phone causes such attempts to fail. In other words, the phone is now in a permanent “closed” state where it no longer accepts any input. The best thing that you can do right now is to call Samsung and let them handle the situation. Their advanced software troubleshooting and solutions are proprietary and they don’t make them available to the public. Otherwise, simply ask for a phone replacement.

Problem #2: Galaxy Note 5 factory reset itself

This morning my phone (in the car, not connected to WiFi) had a black screen with red writing saying it needed to update. When I clicked the home button, it said it was updating, then said it had been reset. My phone reset – as in factory reset! Fortunately, when I put in my email, most all of my info was able to be retrieved from my Verizon cloud. However, I’ve lost some contacts (2 I can tell so far) and cannot get my work email to sync through Outlook. It is requiring a password every 2-3 seconds, but I can tell emails are being received. (I have to use Outlook per ITCS policy here). I cannot delete and reinstall Outlook because of device permissions. Have tried to deactivate first, but it won’t deactivate. Not sure if the reset was due to an update or something else. Not even sure my phone updated! — Jennifer

Solution: Hi Jennifer. We noticed a few documented reports of similar cases in the web, and we even published one before after a Galaxy Note 4 user called our attention to it. As of this time, we are still in the process of investigating the issue and we can’t seem to find a common pattern to be able to trace it to its true cause. Some of the possible causes we are looking into right now includes a possible installed problematic app, a firmware glitch, or malware. Any of these three can be the culprit although we can’t be sure which is which. If you are receiving over-the-air updates from your wireless carrier, make sure that you talk to them about this so they can also offer support if they are aware of the issue.

In the meantime, make it a habit of always keeping a backup of your personal data (photos, videos, contacts, files, etc) in a different platform to minimize data loss in case this issue happens again.

Problem #3: Galaxy Note 5 won’t boot up normally

The phone charged all night and this morning it worked. I dropped the kids off at school and checked my phone and NOTHING.  I have tried to force shut down without success.  At times it would vibrate like it was turning off and then later make the “bell sound” like it was powering up, but nothing on the screen.  It seemed to get stuck in the “bell sound” and would play over and over with a pause between. The last bell would not sound or it would cut off with an “electrical” sound.  The blue LED light is on and not blinking.  I don’t have my wall charger at work with me, but when I plugged it in the car, nothing happened. I have done a power down using the power button and volume down as well as power, volume down, home with no response…Suggestions? — Rene

Solution: Hi Rene. If you can no longer boot the phone normally at this time, the best thing that you can do is to try a master reset. Because you will do this in recovery mode and not in normal boot mode, there’s a big chance that it will work. Keep it mind that this procedure will erase everything in the internal storage device. If you did not create a copy of your data like videos, photos, etc, you will lose them. Here are the steps to perform a master reset for a Note 5:

  • 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.

Problem #4: How to do a master reset on a Galaxy Note 5

Hi Droid Guy. In an effort to free more space, I disabled a bunch of apps I don’t use but are factory installed. Ignoring the warning that disabling such apps could cause the phone to not function properly, I went ahead and disabled. I restarted my phone but now it won’t turn on. It’s caught in a perennial attempt to start. I tried the factory reboot instructions but the screen that appeared had a warning about “installing a different OS”. I don’t have a different OS to install so I just hit the down volume key to cancel.

What should I do? — Sue

Solution: Hi Sue. You are not following the correct procedure to boot in recovery mode, where you can perform a factory reset. You are instead trying to access download mode that’s why the phone shows that “installing a different OS” message. Make sure to follow the instructions given to Rene above on how to do a master reset.
