Fix Verizon Galaxy S5 “Software not updated to G900VVRU2BOG5 Failed…Error Code 550”

Recently, #Verizon rolled out a minor update for #GalaxyS5 and other #SamsungGalaxy devices to address #Stagefright, which affects many Android devices as it is embedded deep in the firmware. It’s an Android 5.0 Lollipop update with build number G900VVRU2BOG5 and is around 300+ MB in size.


More often, users are notified upon the availability of the update but they can also manually search for it via Settings. It can be easily installed but there’s no guarantee it will all be smooth-sailing. In fact, we’ve been receiving emails from some Verizon subscribers complaining about the error they get when trying to install the new update. Here’s one of the messages…

On August 12, 2015, I attempted to update this phone but got the following message: “Last System Update: Software not updated to G900VVRU2BOG5 Failed – Aug 12 2015 at 10:30pm. Error Code 550.” There is no option for me to correct this problem to enable this update. Please advise.”

The issue I cited here is not really not serious. In fact, it’s just a “failed update” and you can always re-try to download the firmware until the installation is successful, although there are other methods to pull down the update from Verizon’s or Samsung’s servers. Here are some steps you can try…

Step 1: Reboot and re-download 

If the first attempt failed, reboot your phone and attempt to download the update again. This is the most basic, yet proven effective for minor issues, troubleshooting procedure. If you’ve successfully updated your phone over the air in the past, then there’s no reason for it to refuse the most recent update unless something not right is at play. For example, during the download, the internet connection got cut off for some reason and since the phone couldn’t contact the server, the error occurred.

So, after you’ve rebooted your phone, check for your internet connection and make sure it’s active and then begin with the download again.

Another reason could be that your phone froze and some services in the background stopped resulting to an error during the download or installation. This is where reboot is very important.

Step 2: Clear cache and data of Download Manager, re-download 

After a failed attempt, some caches and data may have already been saved in your phone and this could be the reason why the second attempt failed as well. All you need to do is clear the files of the unfinished download and attempt to download the firmware.

  1. From any Home screen, tap Apps.
  2. Tap Settings.
  3. Scroll to ‘APPLICATIONS,’ then tap Application manager.
  4. Swipe right to the ALL screen.
  5. Scroll to and tap Download Manager.
  6. Tap Clear cache.
  7. Tap Clear data, then OK.

Step 3: Use Samsung Kies to update your device

If over-the-air update failed after several attempts, there’s another option and this time, it’s more effective–using Samsung Kies. You will, however, need a computer to be able to use this program to work with your phone. If you haven’t used it, here’s how…

  1. Head to Samsung website and download Kies.
  2. Install it on your computer.
  3. Connect your phone to your computer using the original USB cable.
  4. Run Kies and make backups of your data if you so desired.
  5. Pull the update down to your computer using Kies.
  6. Install the update to your phone.

Step 4: Manually install the stock firmware to your phone (optional)

This step is only for people who are willing to take risks. I included this just to let others know this procedure exists. And just like the previous step, you will need a computer to do this…

  1. Download ODIN and install it to your computer.
  2. Download the stock firmware for your phone.
  3. Connect your device to your computer.
  4. Install the firmware to your phone using ODIN.
  5. Wait until installation is complete.

Step 5: Let the tech take care of the problem

While the recent update is a minor one, it is very important because it patches the vulnerability that may allow “others” to take over your phone. Perhaps you should visit a Verizon store and let the company’s tech take care of the problem for you.

You see, if you follow step 4, the warranty of your device will become void but if an authorized tech do it for you, the warranty stays. Basically, if the tech can’t install the new firmware using the standard procedure, then he will have to manually install it.

Important note: If the first attempt failed but the second pushed through, there is a possibility that the phone will be stuck in boot loop after the installation. In this case, you need to wipe the cache partition to force the phone to create new files and you may need to reboot your phone 3 or 4 times to get all apps optimized. Here’s how you wipe the cache partition…

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

Don’t worry, your data will and files will not be touched.
