S5 System Software Not Authorized By AT&T

Problem: Hi. I am using AT&T. I have got an issue that when I switch on my phone a message is appeared on the screen “the software is not authorized to AT&T”. The mobile phone get switched off then. Please help me to fix this problem. I am really confused now.

Solution: It’s either your phone is rooted or it is running on a custom software. Try restarting the phone and check if the issue still occurs. If it does then you will need to flash your phone with its updated stock AT&T firmware file. You can get the firmware file of your specific model from the Sammobile website. Instructions on how to flash your phone are also provided in that website.

S5 Software Update Notification Keeps On Appearing

Problem: I own a Samsung S5 and received a notification earlier this year to update software and so I did accepted the notification. However, after a while I received a notification for a software update once again and whenever I press install, the notification pops up again and now it never leaves my notification panel. I have the Android version 5.0 at present.

Solution: It’s very likely that the problem is caused by a software glitch. Try restarting your phone then check if the issue still occurs. If it does then you should proceed with wiping the cache partition of your phone from the recovery mode. This will delete the temporary system data which could be causing the problem. If the issue still persist then you will have to do a factory reset, Just make sure to backup your phone data before doing the reset.

S5 Stuck In Samsung Screen After Software Update

Problem: I just downloaded an update for a Samsung s5 mini, download completed then it instructed me to reboot it. I did as it said, it went off and now it fails to start. It ends with “Samsung” flashing on the screen, it can’t switch on or go further than that.

Solution: To fix this problem you should first try to remove the battery and microSD card ( if your phone has one installed). Press and hold the power button for at least a minute to discharge the phone circuit and clear out its RAM. Reinsert just the battery then turn on your phone. If it still gets stuck in the Samsung logo then you need to start the phone in recovery mode then wipe its cache partition. Restart the phone then check if the issue is resolved. If it isn’t then you will need to perform a factory reset from the recovery mode. Take note that this procedure will delete your phone data.

S5 Stuck In Samsung Logo

Problem: My Galaxy s5 mini sticks on the Samsung Logo and a blue light stays on in the top left corner, I have tried all the tips (wipe cache partition, wipe data / factory reset) and it’s still on the Logo. What to do?

Solution: Try removing the battery of your phone and the microSD card ( if you have one installed) then press and hold the power button for at least a minute. This will discharge the phone circuit and clear its RAM. reinsert just the battery then try to turn on your phone.

If the issue persists try restarting your phone while it is connected to its charger. If the phone starts normally then the problem could be caused by a faulty battery. Try replacing this battery with a new one.

If the above steps fail to fix the problem then you should consider manually flashing your phone with its updated stock firmware file.

S5 Recovery Is Not Seandroid Enforcing Error

Problem: Galaxy S5 SM G900FZHUIAND1 attempt to reflash  6.0.1 from 4.2.1 android firmware using Odin – obviously the wrong firmware version.  Couldn’t find the correct version on the net – not at any site I could find.  One site assured that the version I loaded was suitable for all G900F versions. After attempt, phone now stuck on boot screen with  Text at top of boot screen is : Blue “Recovery Booting” Red  “Recovery is not Seandroid enforcing Yellow “Set Warranty bit : recovery” Phone is unresponsive and will not factory reset.  Battery removal and replacement makes no difference.

Solution: For this particular issue you will need to manually flash the updated stock firmware of your phone. Try downloading the correct firmware from the Sammobile website. You will also find the instructions on how to flash your phone from that website.

S5 Cannot Activate Device

Problem: I recently purchased a used galaxy s5 from my friend who had att i’m a tmobile customer . I put in my sim card but i cannot activate my device . Some functions work but not all .

Solution: What specific error message are you getting and what functions are you able to access? If you can’t access the network services then the phone might still be locked to the AT&T network. You will need to have this unlocked so as to use the SIM of another network.

S5 Cannot Use Snapchat

Problem: Hello, I have a Samsung galaxy s5 and I’ve encountered problems with using snapchat on it. I can download the app from the play store and it opens to the point where it says login in. I put in my login information and then a box comes up that leads me to a website, the website informs me that I cannot use snapchat because there are some third party app/plugins on the phone that may use snapchat to hack the account. I want to know how can I identify the third party apps it’s referring to and get rid of them to use snapchat, thanks.

Solution: You will have to do a trial and error method in identifying what app is causing this problem. Uninstall an app then check if the issue still occurs, if it does then uninstall another app. Continue with this step until the issue does not occur after uninstalling an app which is very likely going to be the source of the problem.

Another way of doing this is to backup your phone data then do a factory reset. After the reset install the Snapchat app first.

S5 Not Downloading Apps From the Google Play Store

Problem: I bought my unlocked Galaxy S5 in England. I now live in the US. When I try to download apps from the app store it tells me they are not available in my country. I changed my account to US with the app store, still won’t download apps. My google location in turned on. How can I get this corrected so that I can get much needed apps.

Solution: Try clearing the cache and data of the Google Play Store as well as the Google Play Services. Restart your phone then check if the problem still occurs. If it does then backup your phone data then do a factory reset. Once the reset is complete check if the issue still occurs. If it does then try creating another Google account this time with the US as the country of origin.

  1. I have within the last week ported my 2 Verizon galaxy S5 phones to AT&T, I have been to the corporate store 7 times and the AT&T chat 6 times, The main problem I am having is I am within a AT&T 4glte signal area, my signal is H or H+ this is within 7 miles of the AT&T tower, when I get within 2 miles of the tower the signal goes to 4glte, also at the AT&T store, after all the analysis they tell me the Verizon frequency is not compatable with AT&T and my only option is to buy new phones, for me this does not pass the common sense test,
    Can you help me ?
