Downgraded but now want to go back to stock ROM.

Hi, yes I'm new here and new to rooting. I downgraded my phone from 4.1.2. to 4.1.1 using Odin so I could unlock my phone. Now that I've unlocked my phone I would like to go back to the original firmware.

My question is... Will my phone get messed up if I update the firmware using Kies? If yes, then could someone point my in the right direction for safely upgrading my phone to where it was. Thanks : )

Unlocked meaning you rooted it? If yes, then Kies won't recognize it.

I had to downgrade my firmware to unlock my phone to use it with straight talk. My boyfriend used apps in the play store to check if I really did root my phone but the apps said that my phone isn't rooted. So I guess all I did was just flashed a new firmware. I still would like to find out if I should use Odin again to upgrade my firmware or use Kies.

If you decide to use Kies here's an overview of what to do:
- if you don't already have the Kies software installed on your PC, download it (just search Google) and install it. The first time it runs it'll update itself to the latest version so make sure you run it once before proceeding.
- put your phone in Download mode: with the phone completely off, press and hold the Volume Down and Home and Power buttons simultaneously, and release them all when you see the Samsung splash screen
- connect the phone to your PC with the USB cable that came with the phone
-- if you've never had the phone connected to your Windows-based computer before, you'll see messages about installing drivers, etc - just wait until this is done (may take 5 or 10 minutes) [I don't know what happens if you have a Mac - it probably just works]
- in the Kies software, select the second item in the Tools menu and just follow the prompts to enter the model number (in CAPS) and IMEI/Serial Number (both found under the battery - it's ok to remove the battery at this point)
- the Kies software should start downloading the correct firmware for your phone from the Internet; once that's done (depending on your Internet connection speed) it'll begin downloading that to the phone (this probably takes 10 minutes or so)
