"System Software not Authorized" Message after Flashing 4.3 Rom

[Skazzaks]

Hello,

I have an S3 Verizon i535 and I was running a version of Slimrom. I needed to revert back to the Stock Rom, so I downloaded 4.3 and then tried to flash it with Oden. It worked successfully, but then I get the good ol' "System software not authorized by Verizon Wireless has been found on your phone..." I have seen this before - I wasn't too worried. Then I tried to flash a bootloader on, only to find out that that isn't possible once 4.3 is installed. Now, every "Stock Rom" I've tried gives me the same error and I am not sure what to do. Ideally I would just like to install the Stock, unrooted ROM and get my phone working, but I don't know how that is possible.

Can anyone help? Thanks so much.

This is the ROM you should be using http://forum.xda-developers.com/showthread.php?t=2589314 (or http://samsung-updates.com/details/22638/Galaxy_S_3_Verizon/SCH-I535/VZW/I535VRUCML1.html).
Either one of these should return you to stock unrooted, with no weird errors.
