Hi,
I bought a T-mobile Galaxy S3 LTE (SGH-T999L) from a Seller from Craigslist. He did tell me he installed a Custom ROM and right before selling it to me, he reinstalled the Stock Firmware.
What I hadn't realized until after I bought the Phone was apparently the Device Status under About Phone is now "Modified" instead of "Normal" or "Official". Now I can't receive OTA updates anymore (and I guess, not even via Kies).
I downloaded the Root Checker app from Play Store, and what the App says can be seen in the attached images:

I believe the Device is not rooted.
But when I went into the Download Mode, the Custom Binary Download says Yes (1 count), and both Current Binary and System Status shows Custom.
I am just a regular android user and have no experience in rooting whatsoever, and it seems that I may need to do something like this to get this fixed.
Can someone please guide me as to what I should do in order to restore everything to the Stock Firmware and put everything into "Official" or "Normal".
I tried looking for the answers but I ended up getting confused. I know I may need to do Triangle Away, then flash Stock Firmware again, then do Recovery, etc. But at this point, based on my phone's circumstances, where I should start? Since according to the App, it is not rooted anymore, but as far as I know, in order to use Triangle Away, the Phone must be rooted? Or, given my phone's current state, is there a way or shortcut to getting all this fixed (maybe I can skip a few steps)?
I really really appreciate the kindness and help from all Android Central members!
