[All Rooted Androids] Google Play won't download or update. - Android Q&A, Help & Troubleshooting

{note}: this thread made assuming you're android is rooted
Hey. My name is Sadcamp. I'm not really acquainted with how everyone here forums and all, but I'll give this my best shot.
Recently, I was working on fixing my Play Store, because of an app that blocked some of Google Service IP's, disabling my ability to access the store. So, using Root Uninstaller, I removed the Play Store app off of my phone, which as many of you know, removes the Play Store from /system/app. Hoping for it to be fixed, I got an APK of the most recent version and installed it on my phone. To my distaste, nope. I investigated further and journeyed to the mystical file called "hosts". I researched and found that the Google IP's were blocked. So, as recommended, I renamed the hosts file and restarted the device, clearing it all up.
Then, about an hour ago when I went to install an app from the Play Store, it stopped working (at the point where you press Ok/Yes to accept permissions and all). So, I whipped out CatLog, which I recommend if you ever have a problem with your phone, and saw that the phone was giving out messages like "Google Play APK file not found" and stuff of the such. After tracing some of my steps back, I figured this was because, as mentioned in the last paragraph, that I removed the Play Store from /system/app. That being said, I whipped out Lucky Patcher, commanded it to move my Play Store app to /system/app, rebooted my phone, and voila. Just as it had been before all of this crazy stuff had happened.
So, All in all, (TL;DR)
If your Play Store app won't download or update anything, and closes upon opening, consult CatLog, or you could just skip to what I did by using Lucky Patcher and moving the Play Store app to /system/app.
Hope this helped for those who have these kinds of problems. Love your faces!
