I am really "unhappy" that the S5 had their Marshmellow updated prior to the S6. (i have both phones). Get your act together Rogers, Marchmellow has been out for almost a year now, this is insanely rediculous and frustrating. I've about had it with Rogers bloatware on my device too, i think I will just go with the stock ROMs from now on.
PS, Thanks for editing all my swearing, rest assured this post was less nice previously.
Finally the long sought-after update is here. My phone is upgrading as I write this. Been checking the upgrade schedule page every day for months. Hopefuly it runs well!
Writing this post in case anyone had alerts turned on so they will find out sooner than later.
Check above topic, post #15, 16 and 17. You have to call Rogers tech support and ask them reset your network line.
