A shady app rooted my S7, how can I restore it back to normal?

[Harshal Thakur]

I tried to recover deleted photos using an app called dr. fone. The app was downloaded on pc and I connected my phone to the pc via a USB-cable. Before this, I was instructed to tap the version number in my settings to enable developer settings. From the developer settings I enabled USB debugging as that was also instructed.

Tried to recover photos, no bonus. But after trying that, my phone keeps giving the "!" triangle (SecurityLogAgent) notification. And my phone has become EXTRA slow! Some apps keep telling me that my phone is rooted, but the root checker says that root acces is not properly installed. System system status is "custom". I cannot update my software as it tells me to use SmartSwitch or something.

I have tried factory reset. No help. I just want everything to be as normal. Any suggestions for next maneuver? I'm running android 7.0 on a S7 Edge.

Reinstalling stock firmware will require the use of Odin. Her'es a guide from XDA with detailed instructions: https://forum.xda-developers.com/s7-edge/how-to/guide-unbrick-install-stock-rom-samsung-t3550669
