I don't know when it all started, but my S5 began randomly restarting a ton when I installed Facebook and the Messenger app. Naturally, when I could finally get my hands on them, I immediately uninstalled them and set the phone to Airplane mode... but now my phone refuses to work at all. It'll restart constantly and completely every time I try to connect to WiFi, and it gets so bad that it begins telling me to use the Software Repair Assistant sometimes. I have to take out the battery, put it back in, and pray in those cases.
Right now, I'm seeing if I can install the Repair Assistant to back up all my information and try a factory reset... but this will be a long process, and I'm afraid of losing things.
What will happen if, say, this repair assistant FAILS to work, even if all my info is backed up? What would I do then? Is my best bet to try taking it to Best Buy's Samsung Center?
Thanks a lot for your time.
