S5 Verizon Stuck In Software Update Failed Screen

Problem: Verizon software update was unsuccessful and now phone is stuck on “software update failed” screen. Tried hard reboot, and taking out battery, holding down power button, then replacing battery. All with the same result of returning to a the static “software update failed” screen.

Solution: Is your phone rooted? Is your phone running on a custom firmware? If the answer is yes to any of the two questions then this could be the reason why the phone is stuck in the software update failed screen.

There are two way to resolve this issue. First you should try to unroot your phone. While there is a small possibility that the problem will be resolved when you do this it is woryna shot since you won’t lose your phone data. If your phone has the SuperSU app installed then use this to unroot your device.

The second way to resolve this problem is to instal the stock firmware back to your phone. This procedure will delete your phone data so make sure to consider this if you have a backup ready. There are several steps that you need to follow in order for this procedure to be successful. For the exact steps I suggest you check on some of the popular android forums online.

S5 Not Enough Space To Do The Update

Problem: For the past two weeks, my phone tells me I need an update. When I go to update it, it says not enough space. So I went a deleted a lot of unused apps and have plenty of space. When I went to try it again, it says all software is up to date but stays in my notification screen. Although it keeps telling me it is up to date I have found out it’s not. I’m currently on Android version 5.0 build LRX21T.G900AUCU4B0F3. The date it last updated is July of 2015. What’s going on? How can I get it to the latest update??

Solution: The latest build number for this device under AT&T is LMY47X.G900AUCU4CPA1and is around 209MB in file size. However, to get this your phone should be running on Android 5.1.1 with build LMY47X.G900AUCU4COI5 which is an update that has a file size of nearly 1GB.

To be able to successfully update your phone you should have sufficient internal storage space. AT&T recommends that at least 7 GB of space must be free.

The best way to troubleshoot this issue is to backup your phone data then do a factory reset. Once the reset is done you should manually check for the software update using the OTA method. Take note that a stable Wi-Fi connection is required.

S5 Software Update Install Failed

Problem: I have a S5. That shows I have a software update in the status bar. I go to install it. It downloads fine. When I restart the phone it comes back to the AT&T symbol with “recovery reboot” then comes back to the AT&T symbol during the start up and says “install failed” in blue under the symbol then it restarts fine. And works fine after that. I have android version 5.0. Thanks in advance.

Solution: The usual cause of a software update failing to install is the lack of internal storage space. Since your phone is still on Android 5.0 the update you downloaded is most likely the Android 5.1.1 update which has a file size of nearly 1GB. This is however still in its compressed state so it will need more space when installed in your phone.

AT&T recommends that at least 7GB of internal storage space be freed up for this update. If you have already met this requirement and you are still unable to install the update then I suggest you backup your phone data then do a factory reset. Once the reset is done download the update again then check if it is able to install in your device.

S5 Software Update Could Not Be Installed

Problem: AT&T Software Update:  The software update (831.07 MB) could not be installed.  There is not enough space in your device storage.  Move some files to your SD card.

Current status:


  • Phone is 16GB
  • System memory is using 4.51 GB
  • Used space is 4.44 GB
  • Cached data is 4.99
  • Miscellaneous files is 1.49 G


How do I clean up my phone to finish the update?  This phone is only a year old and this seems ridiculous that I don’t have enough space for a software update.

Related problem: Everytime I try to install the new 5.1.1 (Lollipop), the download completes but I get the message that it “failed to Install”.  I tried clearing the cache by turning off phone and holding the power, volume up and home and choosing to clear the cache.  Same thing happens over and over.  Is there another method to get this new operating system.  I also downloaded Smart Switch and for some reason, there’s no option to get the new software besides a box to click to pre-download software.  But when does it start downloading.  I’ve been waiting 3 hours now and nothing.

Solution: You will need to free up at least 7GB of internal storage space from your device. To do this try clearing the cached data of your phone by going to Settings > Storage > Cached data > Clear Cached data. You should also try to uninstall some of the apps which you rarely use. If you are still unable to meet the required storage space then I suggest you backup your phone data then do a factory reset. Once the reset is complete download the update again.

S5 No Software Update Available

Problem: I have tried everything to try to get it to software update… my sister has the same phone and it updates fine but mine won’t. I installed Kies on my computer but all it says is no software update is available for your device at this moment. Also as far as i know my phone isn’t “rooted” i had someone ask me that before. I have enough storage so that’s not a problem i once even deleted every app and tried but it still didn’t work.

Solution: If your phone is not rooted and is still running on its stock firmware then it should be able to get the update. Is the phone still using its original network? An S5 that originally comes from AT&T and is unlocked for use in Straight Talk for example will not be able to get the software update since it needs the AT&T SIM to access the update servers. If your phone is still on its original network then I suggest you backup your phone data then do a factory reset. Once the reset is complete manually check for the software update.

  1. I I did a factory reset on a Verizon Samsung S5. It is currently at Android 4.2.2 (Lolipop). Every time I try to apply the newest software it downloads, but fails to install. I get the following message: “Software update failed, no changes were made” and sure enough I’m stuck at 4.2.2.

    I have tried system restore, clearing the cashe, increasing available memory (8GB free)… you name it. Still fails to update. What am I doing wrong?
