See Post #2 and #3 for the Links to the Firmware
All of the firmware posted here can be flashed on any U or U1 Device. Each of the firmware's are NOT carrier dependent and only has carrier labels listed in order to have an idea if you might get OTA when you flash it.The firmware packages house each of the carrier's information, features, bloat, splash screens etc. (That's why they roll in at over 7Gb). When you flash a firmware the installation package reads your SIM, determines what carrier you're using and then installs the "package" that's designed for your carrier
S908USQU1AVA7 (Totally fake Firmware. I just made it up for example purposes)
S=Galaxy S
908U or F etc, the model of device
SQ, FX etc = CPU and model specific
U,S,E = Update, Security, Engineering, respectively
1,2,3,4,5 etc = bootloader revision (This is important! You cannot go to a previous revision)
A, B, C etc = Android version
U, V = Year (U=2021, V=2022 etc)
A,B,C etc = month (January A - December L)
1 - 9 and then A - Z =build compilation. This basically means how many builds there are in a month. They start at 1 and go to Z
So S908USQU1DVAM would be
S908-U-SQ-U-1-A-V-A-7
S908U (S22 Ultra Carrier version), SQ (Snapdragon), U (Update), 1 (Bootloader version), A (Build 12), V (2022), A (January), 7 (7th build)

BL- Boot Loader
AP - Application Processor (also termed PDA), this is the system partitions, recovery etc,
CP - This is the Modem
CSC - Consumer Software Customization. This is all of the stuff that contains the different carrier features, wi-fi calling, APN stuff like that. You'll notice that this file is getting as big(If not bigger) than the AP file with the system information.
HOME_CSC - This is still the "Same" as the CSC, except it retains the CSC information that is flashed on the device. It wont wipe your device like the normal CSC will. This is part of the package in the OTA that doesn't wipe your phone
USERDATA - Carrier files, this "Brands" the device to your carrier

How to enter Download Mode:
Turn off the device.
Connect USB cable to your PC (Leave it disconnected from the phone)
Press and hold down the Volume Up and Volume Down buttons. While they are still pressed, plug in the USB cable into your phone.
The phone will go into download mode press volume up. In Odin you will see that phone is added.
A decent writeup on how to use Odin:
From samsungfirmware.net How to Flash Samsung Phone Firmware Using Odin
***You MUST use one of the Patched versions of Odin in post #2 or #3 when flashing***
Dirty Flash:
I would only do this if you are having to manually update to the newer firmware and would not do it if you are coming/going to U/U1 or from beta firmware or if you are on an old firmware. I'd also highly recommend doing a back up prior to the doing this
Load these into Odin
BL
AP
CP
HOME_CSC
Do NOT flash CSC or USERDATA (If it's in the download package), either of these WILL wipe your device.
This is a "dirty flash" and these can sometimes cause issues. Keep in mind if things start going sideways and stuff starts not working right, your first step to a solution will be to wipe the device.
