IPhone 5S: I can't view any messages I received in the last month?

Hey y'all, so I've had my iPhone 5S for a year now. No real damage to it. I dropped it in water once, but it was okay after a couple of days. Other than the small, almost unnoticeable water stain in it, it's in decent condition.

About a month ago, I decided I was going to download iOS 8. I reset EVERYTHING on my phone and deleted all of the apps that I didn't need - and could download again once the update was installed - as well as delete every picture, text message, note, etc. Just to make space for this update. Eventually, my phone decided it wanted to go into recovery mode every single time I turned it off. That didn't bother me though because it would turn on just fine after the recovery mode logo (the connect to itunes screen) would disappear.

I downloaded iOS 8, and toward the end of the download, my phone shuts off completely. The recovery mode screen pops up as usual telling me to connect to iTunes, but my phone never turns on after that. Once I finally connect it to iTunes, a pop up tells me that I need to restore my phone, so I click the "restore iPhone" button, but that still didn't work as the recovery screen stayed on my phone.

I eventually gave up, so I haven't used my phone since around the end of October.

Today, I tried turning it on, and for some reason IT WORKED and I set my phone up as a new device. And I thought I backed up all of my data from iCloud, but unfortunately I can't view any texts/calls sent to me in the last month. What's going on?

Thats some dojy activity goin on there!
