Fix status 7 on possibly unrooted, factory resetted moto g 2014

AC Question

Hi all,

I tried to update my Motorola Moto G 2014, but it showed status 7 error. So I contacted Motorola and they said that I rooted my phone. So I connected my phone to my PC and found supersu246.apk. I never installed this, but I guessed somehow some app rooted my phone once. I began thinking and suspected it was when I was desperate to recover my lost photos and downloaded all sorts of programs (possibly Dr. Phone).

So: I deleted supersu246.apk from my internalized SD card and factory resetted my phone. Status 7 still pops up. How do I fix this? I do not want to have a rooted phone btw.

Should I follow the instructions in this link: forum.xda-developers.com/mot...t1068-t3312933 or not?
And specifically the Easy installer attached in the first post at the bottom: it says: 'easy installer.zip to flash your firmware in one click. This also has an option lock or unlock bootloader and warning logo fix.'

BTW I AM A NOOB!!
