S5 Cannot Update To Marshmallow

Problem: at&t galaxy s5  android 5.0. about 2 yrs old. cannot update firmware to 6.0. read all suggested fixes and tried them. kies3 did not work, samsung guy at local best buy said he cannot help. willing to try factory reset if that would work, or any other start over technique. have not tried removing all apps to get to 7 gb of empty storage  (have 29 gb storage on external card if that would help) except that reports indicate that even clearing out virtually all memory may still not work. have everything backed up in hopes that there is a new magic elixir!!!!

Solution: There are several conditions that your phone must met in order for it to get the software update which we have listed below.

  • If the phone was previously locked to a particular network and it was unlocked then it needs to be running on its original network to get the update.
  • The phone must not be rooted.
  • The phone must not be running on a custom software.

If your phone meets the conditions listed above and it is still not getting the update then your option is to backup your phone data then do a factory reset. Once the reset is complete manually check for the update.

If the phone still not update then your last option is to flash the updated firmware file to your phone. You can download the file at the Sammobile website where you can also get the instructions on how to flash your phone.

S5 Unfortunately Phone Has Stopped Working Error

Problem: My wife’s Galaxy S5 (running Android 6.0.1) will pop up “Unfortunately phone has stopped working” when she receives a call while in “any” app. I have rebooted into safe mode and it does the same. I followed your T/S guide and cleared the Cache/Partition info and also the dialer cache. It still does the same. It also will report “Unfortunately the System UI has stopped working” anytime you try a screenshot. Is there anything else I can try before I reset to factory defaults? Thank You!

Solution: Since you have already tried checking if the issue occurs in Safe Mode ( and it does) as well as wiped the cache partition of the phone then the best thing that you can do right now is to do a factory reset. Just make sure to backup your phone data before doing the reset.

S5 No Network Connection Error When Trying To Download Software Update

Problem: My S5 had notified me about a new update but whenever I press download, it says that I have no network connection (I’m connected to our wifi). What should I do?

Solution: It’s very likely that this is a connection related issue. Try restarting your modem/router then check if you are now able to download the update. If the problem persists then try downloading the update when your phone is connected to a different Wi-Fi network.

If you are still getting the same problem even if the phone is connected to a different Wi-Fi network then try to do the update by following the troubleshooting steps listed below.

  • Try updating your phone using Kies.
  • Backup your phone data then do a factory reset. Once the reset is complete do not install any apps in your phone yet. Manually check for the update first.

S5 Software Update Is Temporarily Unavailable

Problem: I have a Samsung galaxy s5 originally verizon network, but is now straight talk (at&t) network. When I try to update my software it gives the message “software update is temporarily unavailable.” I read where the phone has to be activated to reach verizon servers, in which I assume has to he a Verizon Sim instead of at&t. How can I update my phone without a computer?

Solution: Since this is originally a Verizon phone then it must be running on the Verizon network in order for it to get the update. If you are unable to get a Verizon 4G SIM in your phone then your other option is to try to use Kies to update your device.

If using Kies fails to update your phone then you should consider manually flashing the update to your device. You can download the firmware file of your phone at the Sammobile website. Instructions on how to flash your phone are also available in that website.

S5 Software Update Available No Available Space To Download Issue

Problem: My phone has popped up with notifications over the last couple of months/year saying that there is a software update. I never have enough space so I finally deleted a bunch of pictures and apps until I had over 8  GB that it said I needed. Now I go into the check for updates screen and it says current software is up to date and I cannot check again for 23 hours. I still have the notification bar at the top of my screen that says AT&T Software Update Available- no available space to download. And I still have Lollipop

Solution: It’s very likely that your phone does not have enough internal storage space to download and install the update. Try freeing up more space in your phone by moving photos, videos, and other personal files to the microSD card. You should also uninstall apps that you don’t regularly use or apps that are using up too much space. If you already have more than 7 GB of internal storage space free and you aren’t able to download the update because it is letting you check for it again in 23 hours then one temporary fix to this is to go to your time and date settings then manually advance it to 24 hours.

S5 Not Getting Software Update

Problem: hey brother. i need some serious help here. I have a samsung S5 which i don’t know whether it’s a G900f as the phone info says or G900A as the bootloader and baseband version say. well, my phone info says iT’s a G900f and has a G900f baseband. i installed an app called phone info from play store and it says that it has a G900A baseband and bootloader, an AT&T fingerprint build and AT&T CsC. as well as it says that my device type is Klteatt. and its hardware revision is G900A.00 now, it’s running Kitkat 4.4.2 and my actual build number is G900f FZHU1AND1 here are some other additional info about the version Ap:G900fZHU1AND1 Cp:G900fZHU1AND1 CsC:G900fZHU1AND1 i can’t get any OTA update , because The AT&T software update says my phone is up-to date. i’ve just bought this phone from a retailer , used indeed. I’m afraid my phone is a Modified G900A which was unlocked to use my Maroc telecom SIM card. could you possibly help me know how to deal with this mixed up phone and get it updated without getting it locked to AT&T again. if i’s a G900f how can i update it to marshmallow if a have a locked AT&T bootloader and baseband? waiting to hearing from you soon. best regards.

Solution: The best way to deal with this issue is to manually flash the updated firmware file to your phone. If the phone is unlocked then generally it will not lose its unlocked status. You can get the firmware file of your phone from the Sammobile website.

If you are unable to flash the phone firmware due to the bootloader being locked then refer to the various online tutorials on how to unlock the bootloader of your phone.

S5 Keeps On Lagging Even After Factory Reset

Problem: Thank you. My phone is a Samsung S5 2 years old. Running Waze it would often reboot. Even sometime watching a video would reboot. Slowed down a lot. So I did a factory reset. Got all my apps sort of working..but now it seems to lag for 5 to 15 seconds on anything I do. Like type whatsapp and keyboard wont come up for 15 seconds. Scroll messages..delays for 15 seconds then scrolls then freezes. Thanks for suggestions. Btw I did a soft reset but no change

Solution: Do you have a microSD card installed in your phone? If you do then this could be causing the problem. Try removing the card first then check if the issue still occurs.

If the problem persists then you should consider manually flashing your phone with its updated firmware file as the lag issue could be caused by a corrupt phone software.

  1. galaxy s5 (not rooted, but simlock free) does no OTA or KIES3 updates.
    It is stuck at version 4.4.2
    If found the product code / csc with Phone Info (SM2G900FZBASEB / SEB) and thinking about using Odin to update to 6.0.1
    Can I do that directly or should I try to do intermediat updates (4.4.2 -> 4.4.4 -> 5.0 -> 6.0.1)
    if I do not want to lose my apps+data ?
