I rooted my Samsung-sm-g930a (Galaxy s7 AT&T)
And after I did, the VOLTE showed up... I thought nothing of it because it is Voice Over LTE but a week after I did that when i tried to open an app it closed the app 2 seconds later (almost immediately) and if I restart my phone it gets stuck at the AT&T logo I can boot it into recovery and reset the device, this fixes it temporarily then 3 days later it does it Agian. Any idea how to fix this?

  • What's the said app that's force closing? Is your phone doing an update or something? Specifics! What your experiencing is called a boot loop where the phone is stuck at the boot animation. I don't know why it would do that after three days but an app or mod you installed can be causing it.

  • @JCTechie The only root app I had installed was Super SU and I did not "mod" the phone or Anything... The only thing I did was go into /data/data/com.505Games.TerrariaPaid and I replaced a few of the worlds. Corrupted things in a game wouldn't screw up the whole phone would it? And, it's all apps doing it, besides settings and chrome Jan 25 '17 at 13:45
  • @Donovan_D I think the easiest solution for you is to factory reset your phone, and re-do the root process. It sounds to me that something got messed up when rooting, and you need to start over. You can backup your contacts and game saves with google or get an app that does that for you (titanium backup can restore your app data)

  • @JCTechie I did a factory data reset, it still does it 3-7 days later Jan 25 '17 at 18:23

It appears that something wrong has happened with your rom. Since factory resetting has not fixed the issue, the next step is to restore the stock rom. Here's a link to the stock rom for the Samsung Galaxy S7:

  • -1: you offered a "stock" ROM for the wrong model (G930F uses Exynos, G930A uses Snapdragon) that would wreak havoc if actually flashed, and it's a stock-based ROM flashed from a custom recovery, not a real stock ROM flashed via Odin, so it's of little use for fault recovering.

  • I just looked it up - weird that both SamMobile and Samsung-Updates don't offer firmware for this particular model. Some over at XDA does seem to have one, so editing this in is at least better than not. I'll retract the -1 after your edit.

  • @JCTechie I think I found it here: forum.xda-developers.com/att-galaxy-s7/how-to/… Jan 29 '17 at 17:12

I ever faced a situation like this where my phone load until the Samsung logo and that's it. What I did was installing a stock rom in to my Samsung and it did fix my phone. You can visit the web of cyanogen to see if your phone model is listed there.
