I tried to flash that AT&T firmware from Sammobile and it wasn't an AT&T branded update. I also have the unlocked variant with the U firmware installed for AT&T. I believe the firmware in the 2nd post doesn't have AT&T carrier information in it also as i flashed that one too and it didn't work right. We'll just have to wait for AT&T to drop their update.
[Samsung Galaxy S22 Ultra] kangi26:
The branding in the Carrier firmware is due to typically the carriers will a lot of times not be on the same versions. IF the Unlocked versions become "unsync'd" there will be a carrier name next to it.

If you are on a U firmware you must be on a ATT (In your case) firmware release to get U OTA. If you're on a U1 firmware you must be on ATT (in your case) firmware to get U1 OTA. Does this answer your question?
[Samsung Galaxy S22 Ultra] Maxninja:
If you're saying that if I flash the U1 ATT firmware and continue to receive OTAs, then yes it answers my question. And I appreciate it :)(y)

So.. the U1 gets OTAs first and then the carrier will send the update to the U sometime later? ::sigh::
[Samsung Galaxy S22 Ultra] kangi26:
It really changes quite a bit, sometimes U gets them 1st, other times U1 does. It'll become a bit more obvious as time goes on, they will get disjointed as the releases move on. If you take a look at post #2 and #3 HERE, you'll see what we can expect ;)
[Samsung Galaxy S22 Ultra] butchieboy:
Has anyone with Firstnet Sim received an OTA on U or U1? I was just curious about this. I know Firstnet is through At&t but I have not seen it mentioned.
[Samsung Galaxy S22 Ultra] DLD23:
Actually if you go back a few pages and download

For reference- how do you get into recovery mode when things go bad?
[Samsung Galaxy S22 Ultra] DLD23:
There is only 1 u1 firmware btw. It reads carrier and assigns csc. No userdata file for that one.
[Samsung Galaxy S22 Ultra] Maxninja:
This is ambiguous. Do you mean there is only one U1 firmware for AT&T (which is false; there's two firmware files for ATT U1, pic for reference) or in the U1 tab, you mean there is ONLY one file? (again, if you look in the attached pic, it is also false)
[Samsung Galaxy S22 Ultra] kangi26:
To get to Recovery, with Pwr off, press and hold pwr+Vol Up
[Samsung Galaxy S22 Ultra] kangi26:
I think his point was that for AVC8 all of the carrier builds are all the same. You can download ANY one of them and it would be the exact same firmware that can be flashed on any S908(U and U1) device. Because the firmware revisions are the same if you downloaded the AVC8 one labeled TMB, you could flash that on any 908U/U1 device and it'll model the carrier firmware that you have a SIM for your device
[Samsung Galaxy S22 Ultra] Mtotallywired:
Shared this in the recent battery life thread but thought it pertinent to repost here as I got a lot of the info and resources from this thread:

Got my phone on Feb 21 (snapdragon 512 at&t) - lived with the crap battery life until about 3-4 days ago when I started having serious issues with messages not downloading. To help troubleshoot that i flashed latest unlocked U1 firmware (avc8) and I am currently on Day 2 with it. Had been getting absolutely awful battery life and issues with messages not downloading. like only 4-5 hours on AT&T firmware.

After clean flashing U1 followed all the steps in this thread, up until the adb debloating which I didn't do: https://xdaforums.com/t/no-root-samsung-optimization-guide-debloat-tweaks-settings-and-adb.4376755/

Then Got these results after wiping cache / repairing apps / and installing good guardians - app booster and one cycle of battery calibration.

This is on WQHD / 60-70% brightness / adaptive refresh / no adaptive brightness / no battery saver / no adaptive power saving / mobile data off - since am on wifi all day bc covid. Disabled Chrome and using Samsung Internet and set all apps to deep sleep, except messages. Put gmail, google photos, Spotify, banking app, vanced to sleep.

I know running video for hours at a time is not an example of real world usage but just wanted to see if my phone could even break past the 5 hour mark with SoT and was surprised to see almost 10 after all those tweaks. Trying to use it more normally today and expect the system to improve more as it learns my usage. Will report back.
[Samsung Galaxy S22 Ultra] kangi26:
Sweet bah-jesus .......

I'm on ATT/U1/WQHD/Adaptive brightness, 73% 1hr 17min SOT since last full charge

I might have to reset and start from scratch again,

AT&T Carrier Rolling OTA
[Samsung Galaxy S22 Ultra] kangi26:
Any idea what build they are using? AVC8 maybe?
[Samsung Galaxy S22 Ultra] Venom0642:
AVC8
[Samsung Galaxy S22 Ultra] kraz01:
Would an unlocked S22U flashed to AT&T get the update or would I have to flash the update?
[Samsung Galaxy S22 Ultra] kangi26:
In order to get the OTA Venom is referring to, you would need to be on a Carrier firmware
[Samsung Galaxy S22 Ultra] Kris_b1104:
Yup, I flashed U1 AVA6 from post #2 the day it got posted, and received the OTA update yesterday. I was originally on carrier locked AT&T U firmware.

I'm now on AVC8 U1 AT&T
[Samsung Galaxy S22 Ultra] kangi26:
I'm not sure folks understand some of the basic OTA rules. Lets see if I can lay it out to hopefully make it simpler to understand. It can really get confusing sometimes. I think it could come in handy when the build numbers get mis-aligned

I'm going to use the Carrier Firmware as my example here not the Unlocked (U1) Firmware.

The firmware is very specific to each carrier, each carrier has the build and does their own specific work to it. ATT does, VZW does, TMB does, etc. They do their work and then release them with specific build numbers (See post 1 for an explanation of what the build numbers signify), but it so happens that right now they are all aligned with the same build numbers. Very quickly this will not be the case and the build numbers will become different for some of the carriers and then might align again.

Let say that on July 10th, ATT releases their June 1 Security Patch S908USQS1AVFA (This is June/Build A), and then a couple days later TMB releases their June 1 Security Patch and it's S908USQS1AVFG (This is 2022/June/Build G). These are 2 very different builds for the same security Patch (This applies to Updates too).

The way things work is that ANYONE with a S908U(Or U1) device can flash either of those firmware, and it'll run just fine. The big thing to remember here is if you happen to be on TMB and you flash the ATT build, you will not get OTA because you are not on an "Official TMB" firmware, in this example the official is the S908USQS1AVFG build. Those build numbers need to match exactly in order to get OTA.

This exact same thing applies when you're on U1 firmware as well, and even more so when we throw in the ability to flash either a U or U1 firmware.
[Samsung Galaxy S22 Ultra] butchieboy:
Venom is this U update?
[Samsung Galaxy S22 Ultra] butchieboy:
Kangi I'm glad you posted that because there are some that don't understand that the minute a carrier launches a firmware with a different build and they are not in line with whatever their carrier released they will not get Ota. At&t is notorious for that..plus the fact that they do not release their locked firmware.
[Samsung Galaxy S22 Ultra] littlemegaman:
Hi yall...

I want to clean install U1 Firmware.

Device: SM-S908U1

I installed TMobile U Firmware using all 5 files, then reverted back to U1 using all 5 files again on ODIN each from its respective .zip

(This was out of curiosity to see which Firmware ran better and see if it addressed a few oddities, didn't see much difference.)

Now I'd like a true clean install of U1 to test the new AVC8 update because after reading flash order and variances, I'm doubting I've done a true clean install.

I know BL, AP and CP fields on ODIN need their corresponding files. Got it.

However, the confusion is with CSC and USERDATA. First post says flashing either WILL WIPE device.

The question is, for a clean install, is it both slots need files or just one?

For example is this correct? Because this is how I've been flashing so far.

CSC slot: CSC_OYM_S908U1OYM1AVC8_MCL...

USERDATA slot: HOME_CSC_OYM_S908U1OYM1AVC8_MCL...

Or Leave USERDATA blank? CSC blank? Maybe I'm just overthinking here, but its also been a long time around here, coming from a Note 9.

I'm looking to see if I can get the "Service provider software version" back to factory: XAA/XAA, XAA/XAA

I suppose to do that, I have to:

1. Remove Sim Card

2. Factory Reset

3. Run thru Setup Process without installing or logging into anything.

4. Shut down.

5. Enter Download Mode and begin Flash.

Appreciate any input guys, thanks!
[Samsung Galaxy S22 Ultra] butchieboy:
Thanks buddy. I will try to grab update.zip for it if I can with http:canary
[Samsung Galaxy S22 Ultra] DLD23:
I sense trolling lol. All needed info has been posted on this thread except new releases. People get too emotional over technicalities. Recommended thread lock except new releases.
[Samsung Galaxy S22 Ultra] butchieboy:
Trolling? Can you explain?
[Samsung Galaxy S22 Ultra] Jobudden:
Just because I don't see that anyone reported it yet..

Just got the AVC8 OTA on Verizon lol
[Samsung Galaxy S22 Ultra] kangi26:
Flashing either one will wipe. Typically the U1 firmware didn't have the USERDATA file.

It's either the CSC or the HOME_CSC that would go into the CSC slot.
[Samsung Galaxy S22 Ultra] kangi26:
I would never support locking the thread, it's how everyone learns and has some fun too
[Samsung Galaxy S22 Ultra] DLD23:
Thanks. I appreciate the clarification.

Respect :) I will communicate more clearly and in better detail when I give feedback. But there is only 1 U1 firmware lol(per release) that applies to all carriers. And never in a U1 release is there going be a splash screen. And never does userdata get flashed with u1 firmware. Correct if I am wrong plz. I learn something new every day :) edit- i am only specifyiing Snapdragon. Opps that may have been my errpr.
[Samsung Galaxy S22 Ultra] littlemegaman:
Thanks kangi26,

USERDATA stays blank, got it.

What does either "CSC_OYM" or "HOME_CSC" file do?

In other words, what are their functions?

Which is best to use for CSC slot?
[Samsung Galaxy S22 Ultra] littlemegaman:
Figured it out, CSC_OYM, or 4th file on picture into CSC slot to wipe data, like new phone.
[Samsung Galaxy S22 Ultra] Matth943:
Probably not to many Firstnet users here. I have a U1 device flashed with the U (what I believe is the ATT firmware), I am still on the January patch. No sign of any OTA updates.
[Samsung Galaxy S22 Ultra] dia_naji:
Really Appreciate the explanation. The firmwire names and this whole process can get extremely confusing.
[Samsung Galaxy S22 Ultra] kangi26:
I'll also add (Should have done this in the original post)

The files that we use and what they basically are

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

EDIT****

I added this to the OP
[Samsung Galaxy S22 Ultra] kangi26:
The USERDATA doesnt come with the U1 firmware because this (in part) contains things like the carrier splash screen and branding etc, that isn't a part of the Unlocked devices
[Samsung Galaxy S22 Ultra] kangi26:
I did a factory reset last night, reinstalled everything from scratch (no data or app import) and have charged to 100%, lets see if I can get better battery life out of this little piggy.
[Samsung Galaxy S22 Ultra] butchieboy:
Lol...I'm still losing about 8% overnight. I might do that or wait to see if I get the OTA on At&t (U)
[Samsung Galaxy S22 Ultra] kangi26:
I'm on U1 and I wanted to wait till after I got the latest update, so we'll see........
[Samsung Galaxy S22 Ultra] Jobudden:
Let me know fellas I might need to do the same
[Samsung Galaxy S22 Ultra] kangi26:
Sure thing. I'm not TOO optimistic right now, but I need to be more patient and let it settle in
[Samsung Galaxy S22 Ultra] dia_naji:
I was getting about 6-7 of SOT with the U1 official firmwire. Flashed the U TMB yesterday. I am not expecting more SOT, but the same would be great
[Samsung Galaxy S22 Ultra] Matth943:
Hey Kangi - I’m new to this site and tried searching for solutions between here and Reddit. Can’t find a clear answer, hope you can help.

I have a 908U1 flashed with the TMB U firmware. Flashed it because Firstnet doesn’t provision properly to ATT on the U1 firmware (unless this has changed). Phone shows Att/att,Att/Xaa.

My questions:

Will I get the OTA updates from ATT?

If I don’t/wont get the updates from ATT, what is your recommendation to stay up to date?

I appreciate it.

-Matt
[Samsung Galaxy S22 Ultra] butchieboy:
I believe csc needs to be the same in order to get ota
[Samsung Galaxy S22 Ultra] kangi26:
So to be totally honest I don't fully understand how FirstNet works. I can tell you that if you flashed a U firmware and used the CSC (NOT the HOME_CSC) allowing the device to wipe, because you're using the latest stock I imagine you will get OTA. I can only assume that it'll come from ATT(?) Maybe @butchieboy would know?

As far as the ATT/ATT,ATT/XAA, that I believe is your SIM's, the 1st set shows the active SIM you have in your SIM tray, after the coma that would be your eSIM configuration. (so I'd assume you're not using it).

If it were me, I'd stay on the current firmware and see what happens when the next ATT update drops for U and see what your device does
[Samsung Galaxy S22 Ultra] Jobudden:
Actually I may not have to. After last night's update, I have pretty decent battery life.
[Samsung Galaxy S22 Ultra] Matth943:
I gotta double check which Csc. I know i followed the instructions on another post from here. May have been the original on this post.
[Samsung Galaxy S22 Ultra] Matth943:
Thanks! I appreciate the input. From what I know about FirstNet, it runs on ATT‘s specific firmware. I know there’s a file in the U and U1 firmware that provisions carriers. For whatever reason, the U1 firmware doesn’t provision at all for FN. The U firmware, if you flash it with an old or inactivated ATT sim in it, it will provision the phone for ATT. Then you can put the FN sim in the phone and it won’t reprovision it to another carrier / unlocked.

I am 95% sure I used the Csc file and not home csc. Basically I was told to get the ATT specific features like volte, Wi-Fi calling, etc working, flash the phone immediately before putting the FN sim in it, so I don’t see why I wouldn‘t have fully wiped the device.

I believe that it is the sims, I just wasn’t sure if it is relevant for this. I am using regular SIM card, esim wouldn’t work for whatever reason on FN. The tech in the store was useless.

Sounds good. I’ll ride it out for a while and see what happens.

I'm also on FirstNet. I'm just going to wait to see if an update get pushed to my phone. If not then I'll see if someone uploads the AT&T firmware. I tried flashing the TMobile updated firmware and it didn't provision the device for AT&t with the AT&T sim card in it.

I'm a battery whore.

Wait, can I say whore?

Guys, after coming from the Galaxy S III, Note 4, S8+, Note 10+, and now finally the S22 Ultra, I am in love. I might be a little biased because the 2 previous phones that I held to a high standard were the Note 4 & Note 10+. This phone blows them out of the water. My favorite thing is being able to switch between performance modes, and even when on the lowest setting, the phone never lags; neither does it hurt the battery on the highest setting. There's a new King in my books.

It's the pain we have to live with sometimes when we just feel the need for the "latest and greatest" ;)
[Samsung Galaxy S22 Ultra] NotATreoFan:
What I'll probably do in order to make it less painful when the firmware inevitably comes out is skip setting up Samsung Pay, Google Pay, and my car's digital keys. I'll just have to suck it up and use the actual keyfob for my car.

Whenever I get a new phone, I only transfer SMS since I don't trust system data to copy over without issue.

[Samsung Galaxy S22 Ultra] Matth943:
This is true for U variants. My note 20 had no issues getting it. Most techs no nothing about U1 flashing. Last time I called in they told me I need to buy a new phone direct from att.

No they do not. Usually the only one available is what device ships with then after that nothing.

It doesn't. U1 firmware shows the normal LTE logo
[Samsung Galaxy S22 Ultra] Apathyyy:
That's what I thought too but for some reason when I got my unlocked s22 ultra today it's showing the hideous Verizon 4G LTE logo
[Samsung Galaxy S22 Ultra] kangi26:
Please keep in mind there is no "TMB" or "VZW" firmware.

As of this moment, ALL of the U firmware are exactly the same, they are on the exact same build #. Yes ATT rarely publishes any of their firmware, but once they push OTA we can see what the build number is and most often than not, it's the same build as one of the other carriers, so it doesn't matter at all
[Samsung Galaxy S22 Ultra] kangi26:
I'm almost matched to your experience exactly today
[Samsung Galaxy S22 Ultra] Jobudden:
If you're still in your settling period yours may be better in a day or so
[Samsung Galaxy S22 Ultra] Matth943:
I appreciate that clarification. I thought that there was some differences, but wasn’t sure how big. I think I was thinking of the carrier files that get loaded with your SIM card.
[Samsung Galaxy S22 Ultra] kraz01:
If you are using a Verizon sim card. It will change the it on first boot sometimes.

Helped me achieve optimal performance and the 9hr 45min SOT.

I didn't do any debloating whatsoever. Just the adb commands and suggested battery saving/performance settings. It's your choice. Did you do a fresh install without copying any data over? Tried flashing the U1 firmware to see if it's better?
[Samsung Galaxy S22 Ultra] Apathyyy:
Hmm interesting. Really driving me nuts this LTE indicator is hideous
[Samsung Galaxy S22 Ultra] littlemegaman:
Hey did you ever figure this out??

Would appreciate any help on resetting this to factory.

Was hoping clean installing U1 would reset service provider to brand new out of the box settings XAA/XAA, XAA/XAA, but it remains the same, in my case TMobile TMB/TMB, TMB/XAA even after flashing without the sim card.
[Samsung Galaxy S22 Ultra] butchieboy:
So, I recently switched to Firstnet which is still At&t. Was not getting the OTA. So I removed my Firstnet Sim and put my regular At&t Sim in S22ultra, changed date to April 6th checked for update and it started. Now I don't know if it was because I switched Sim or because I set date so far ahead. I am on (U) version. Just thought I would pass this on if you have Firstnet.
[Samsung Galaxy S22 Ultra] butchieboy:
So to have a better answer for you all, I will disable the update, put Firstnet Sim back in set date to April again and see if it works
[Samsung Galaxy S22 Ultra] butchieboy:
Well that didn't work now saying no update..lol
[Samsung Galaxy S22 Ultra] kraz01:
did you use an activated at&t sim card?

Didn’t work for me by changing the date or using an inactive/active att sim. Oh well.
[Samsung Galaxy S22 Ultra] dj24:
Mine is at about 6% for about 8 hours of standby overnight. Maybe others can post theirs to let us know where we fall in the pack..
