[Android Central Question]

I had an on line company do a ver 7 root remotely. It worked ok at first but they must have forgot to turn off updates or something. It tried to install an update then when it rebooted no launcher would load I had no icons. I finally got into the setup and was able to open the play store and install a launcher to get some icons but it still. isn't working right. It says its customized but various programs tell me it is not rooted. I would like the new ver 8 os installed for my AT&T S7 Edge, the funky Samsung splah screen set back to normal and the customized status changed back to genuine. I'm told the flash counter needs to be reset to 0. If this is not possible i will settle for re-rooting the phone withe the version 8 S7 Edge software. Bottom line in need this phone upgraded and workable one way or another.

Not possible since about KitKat.

To put back the normal version, just find the ROM for your model S7, for your country, for your carrier (sammobile.com/firmware is the first place to look) and use Odin (see [Samsung] How to flash Stock ROM via ODIN). You'll lose everything that didn't come with the phone - the ROM only has Android, not your pictures, music, etc. So if you can, back all of that up first (see Backing up an Android Device).

We don't allow that sort of thing here for many reasons - one of which is that you could easily get scammed. If you want to root the phone after flashing the ROM, try Magisk General Support / Discussion (downloads at Magisk Releases· GitHub).
