So, I have the droid razr HD and today as I was using it, it simply shut off. When I attempt to press power+down volume it goes the the red M dual core screen and does nothing else. At the time it shut off I was in the middle of uninstalling the facebook app since I never use facebook anymore but I dont see how this could have caused this to happen to the phone. I attempted to do factory reset and it said it was successful however I could still not get past the M startup screen.
I have never rooted or unlocked it, yet everything I have been looking up seems to indicate that a lot of failed attempts at doing that causes this. The only thing I can think of that would be a reason was that about 5ish weeks ago I broke the screen. Being that I am pretty busy(and lazy) I took the phone to a local computer repair shop to have them fix it. It took them quite a long time to have it completed. After I got it back(about 2 weeks ago) I of course had many missed texts/calls and the weird thing was that some were dated in october 2018. I thought nothing of it but at this point I'm beginning to wonder if the shop that fixed the screen rooted the phone and screwed something up? In the AP fastboot its says locked status 0. I'm no expert in phone software so go easy on me.
Any help would be greatly appreciated in how to fix this.
