Updating software unlocked phone
To improve the speed of the download, avoid downloading other content or use a Wi-Fi network if you can.Try updating your device again using the same network.
Second, I would suggest you visit sdx-developers.com, a samsung site and read through rooting and what roms are available there.With i OS 9 and later, if there isn't enough space to download and install an update, your device will try to make space.It will remove parts of apps that it can download again.(Scroll down midway on the download page to see the instructions). I know that Rogers tends to add their own bloatware at times.The firmware includes the latest security patch dated 2016-07-01 . Since my phone isn't a Koodo branded phone, I'd like to avoid any unnecessary extras if possible. I checked my CSC code, dialling *#272*your IMEI# and it came up as MTA. It seems when I put my Koodo SIM in, it didn't change my CSC to Koodo.
