Your phone will be stuck with using the 3G network.Hi, I have samsung S5- was originally bought from AT&T and then i switched to T-mobile almost 2 years ago.We however ask that when you do contact us try to be as detailed as possible so that an accurate assessment can be made and the correct solution can be given. a software update notification pops up, goes through with the process I press install, the phone reboots and finishes the installation. the software has not updated I’m still on version 5.0 I decided to do a factory reset hoping to solve the problem but unfortunately it did not help at all.a message pops saying the software has been updated, no error codes whatsoever and then a new software update notification pops up, and does it again. You should try updating the phone by connecting it using a USB cord to a computer with Kies running.Nothing shows up on the taskbar and when I check my settings for an update, it states that there is no update found.
For basic checks, register for an online services account instead of using the Update Service.
Once the reset is complete download the update again.
I have the s5 sm-G900A, with baseband version G900AUCS4CPA4. Each time I check with Odin, OTA, Kies it tells me my software us up to date.
This is already a hardware limitation which can’t be fixed.
If you plan to proceed with the switch then you won’t be able to enjoy faster mobile data speeds that the LTE network offers.I need help to get updates to get me to the marshmallow os.
