Did a factory reset on a 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?
