So, I acquired the factory mode firmware for this device, and I was wondering if there was a way to get the secure check on the boot loader disabled from within it. Honestly, the whole menu is confusing.
No chance, the bootloader is as locked down as any other.
The factory firmware is for diagnostic purposes and testing the device by engineers.

Does anyone know where to find an alternate link to the engineering boot found here for the sm-s550tl? How do they manage to even get these kind of things?

A revision 1 boot image will not flash on a device with revision 2 firmware using Odin.
It can be force flashed with alternative methods, but may not even boot.
People need to behave and not update for the sake of it. Its either root or update.

I am still on the APG1. For whatever reason, I can't seem to receive the update to go to AQC4.

Is the eng boot, so what's your point?
I'm sorry, I should have been clearer. The reason I'm wanting to update is because im hoping it will fix my imei problem. It got zeroed out after unlocking. Without a backup, I think I'm pretty much done for as far as making and receiving calls and text and data. I tried everything I could find to fix it, but it's looking pretty hopeless.

Then I suggest you download the stock update from updato.com and apply the update via odin.

Sometimes deleting the entire EFS folder will repair the IMEI as it will be rebuilt at next boot, at the very least it usually gives a default IMEI.

The EFS also usually has a backup of the NV_DATA. Which can be used to restore the IMEI if it's not also corrupt.
It's wise to make a backup of the EFS folder/partition before doing anything.
