Upgrade OS on Samsung Galaxy S3 (North Portland) hide this posting unhide
QR Code Link to This Post I have a Samsung Galaxy S3 running Kitkat and I want to upgrade it to Nougat 7.1.1
I have called many cell phone repair places and they say they can't do it.
There are quite a few how-to videos on youtube showing how to do this procedure--even without rooting, which is my preference. Of course, it is a custom ROM by Lineage that is actually used since CM is no longer available. I started following one video and it didn't work. So, I need someone with experience who has done this same exact thing. I don't want someone who thinks they can do it but has never done it successfully. If you are qualified and interested, please contact.
