How To Guide OTA and Non-OTA Firmware for S22 Ultra SM-S908U and S22 Ultra SM-S908U1 Versions

What firmware is your device on right now?
Edit:
I would go into DL mode and wipe Data, clear cache, then download the most current firmware (Either U or U1) and flash your device. Use the Odin that's posted in #2 or #3 and flash:
BL
AP
CP
CSC (NOT the HOME_CSC if its available)

How to wipe Data, clear cache in DL mode ? Is in Odin with Nad erase + Re partition or ... ? Thanks
DO NOT Re-Partition,
Dont mess with ANY of the default setting in Odin, ONLY add the files and run
Press and hold Power/Vol up until after the "Samsung" splash screen.
Use the Vol up/down to navigate, power button will select.
Navigate down to "Wipe Cache Partition" press power then once again to confirm Yes
Navigate to "Wipe data/factory reset", press power to select and again to confirm yes.
after it completes, navigate to Power off, then flash the firmware
Leave EVERYTHING as default on Odin, then flash the latest firmware by selecting everything: AP, BL, CSC (standard CSC not Home one) and USERADATA. In this way you'll clean flash the firmware and your device will reboot complitely resetted
I've flashed U1 firmwares on Snapdragon devices from other countries using a patched Odin. That's how I've turned the Canadian model into the American for example. I just got the Korean S22 Ultra (S908N) and I'm wondering if I can flash the U1 firmware onto it with this patched Odin. I'm already downloading the U1 firmware so wish me luck!
Not likely, the firmware is "designed" for the U/U1 versions and it'll error when it sees a 908N

Are you on TMO firmware? That update (AVE4) is broken as far as that goes. I got it to work momentarily by removing the SIM Card and playing around with it, but ultimately it went back to "verifying". I downgraded back to AVDC (U1) then the AVE4 dropped for U1. Been fine since reverting back to U1 firmware.

Yeah, been trying some stuff with no real results. It's not killing me to not have RCS, but was checking in case someone found a work around.

On the U1 firmware does your sim card have the listing for calls and messages as active? I was having a thought yesterday.

4Whatever bloat your current Sim has, you will get. I believe even if you dirty flash it will detect your Sim regardless. If I'm wrong someone will jump in.43
Go to playstore install Samsung Band selection now follow my pictures.33 -

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:

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 thisLoad these into OdinBLAPCPHOME_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.12S908U - Carrier Versions
Bootloader 2 - If you are on a Bootloader 2 firmware you can NOT go back to a Bootloader 1 firmware, there is NO workaround.

I would never support locking the thread, it's how everyone learns and has some fun too7
There's VERY little chance you'll brick (The only way that I know you can is pulling the USB cable when flashing), that aside, it'll just error before the flash could happen.
That being said, If you have a S908U or S908U1 device you can flash ANY of the firmware on this post. The firmware is not Carrier agnostic, the only reason there are carrier tags next to the posted firmware is to let people if they flash a specific one whether or not that is the current stock one and will get OTA in future releases.
Most of that info is in the OP (I think.......), and if you're not too familiar with the process, I highly advise taking the time to read thru the pages, almost everything you'll need to know has been posted.
If you can't find something ask, most everyone is super helpful
