Yeah I know about that site. I mean more about a thread with discussions on how the new firmware is. Snapdragon is in a lot more regions this year. Feel like we should have one more thread. Currently just having the US Snapdragon and the Exynos variant doesn't really cover all of the other versions of the phone. I get we can't have 50 of them, but can't we have one more thread for that?
[Samsung Galaxy S22 Ultra] kangi26:
No this is only for S908U and U1. You'll have to look to see if someone has made a thread for that device
[Samsung Galaxy S22 Ultra] butchieboy:
Are all you jerks enjoying your new devices?🤣😂🤣😂🤣
[Samsung Galaxy S22 Ultra] joancolmenares:
Since BestBuy screwed up my order I asked for a refund and got the device from my carrier (TMOBILE) so I have the Tmobile version but Im tempted to flash the unlocked firmware mostly for the updates as carrier updates take longer to be available. Not sure yet...
[Samsung Galaxy S22 Ultra] vendetta17:
Hi guys. Im not sure where to ask but i am a little bit stressed with the battery life of the phone i just ordered. I use manual brightness at about 30%. I use wqhd+. Im not overkilling the phone. I do some YouTube, mostly twitter. I dont play games.

I rarely gey over 5hrs SOT. Is that normal ? Im. Quite disappointed. Im trying to find out if its the same for you or mine may be broken. I still have some days to file return just in case its broken. Thanks in advance.
[Samsung Galaxy S22 Ultra] dj24:
We get to live vicariously through them..:giggle: Mine is on track to be supposedly delivered on March 4th. I truly believe Samsung is going to process it, take the money out of my account, create a shipping label and deliver it on time exactly 3 days from now :unsure:
[Samsung Galaxy S22 Ultra] kraz01:
The battery will get better once the learning pattern is over. Here is mine a few days ago mostly on wifi. While I'm at work the cell signal puts a dent in the battery.
[Samsung Galaxy S22 Ultra] Venom0642:
No issues here with battery life AT&T S22 Ultra 5G 512GB Snapdragon. And that's with brightness manual set at 93% plus extra brightness is on with 120hz and display at WQHD with processing speed on and getting good battery life.
[Samsung Galaxy S22 Ultra] vendetta17:
After seeing this, think ill get rid of this phone. Being happy when i reach 5 hrs SOT with 30 % brightness aint fun. This is not what i paid 1500 pounds for.
[Samsung Galaxy S22 Ultra] kangi26:
It's obviously your decision, but I wouldn't make comparisons to anyone else's experiences with SOT. There are a HUGE number of reasons that you may be seeing lower SOT than you're expecting to. I'd consider doing a factory reset and at set up do not automatically restore anything
[Samsung Galaxy S22 Ultra] vendetta17:
I was thinking of doing this. It may be the last thing to try before a potential return. I love the phone but its so frustrating. I already had enough of seeing this... Full charge today and after few hours i got this...

will flashing to the u1 firmware fix the RCS issue with att ?
[Samsung Galaxy S22 Ultra] kangi26:
I can't speak to what might be going on with the U firmware, but I'm on U1 and I get RCS with Google Messages on AT&T (I'm also running the beta of Messages, so I don't know if that makes any difference or not)

Edit.....

@GTR_Ramsay the U1 is different for RCS, it uses Jibe for RCS services, not AT&T.
[Samsung Galaxy S22 Ultra] GTR_Ramsay:
thank you so much !!! that info just helped me alot !!!! ill be buying unlocked samsungs from here on out.

looks like ill have to do a flash to what you have . i think its the u1
[Samsung Galaxy S22 Ultra] kangi26:
You dont need to buy a U1, I'd go with the best deal $$ wise. At least in this moment in time, there isn't any huge benefit for having a U1 v.s. U device when we can just flash the firmware and just make it one or the other
[Samsung Galaxy S22 Ultra] looney2388:
I'm on Verizon and flashed unlocked U1 firmware. I don't have a VoLTE option in settings-mobile networks.

Edit: I found the option. I downloaded Samsung Band Selection off Play Store. Selected more network settings and I can now toggle it on and off. I'm gonna leave it on.
[Samsung Galaxy S22 Ultra] Jobudden:
This mine is a locked Verizon device
[Samsung Galaxy S22 Ultra] Venom0642:
Your imei are on there should remove it.
[Samsung Galaxy S22 Ultra] Markeee:
Seems to be something different between U and U1 phones ?

I'm on Xfinity mobile and when I check IMEI compatibility on the below link compatibility checker only U1 phones are compatible all U carrier phones that are not Xfinity specific always show up as incompatible ?

Not sure why maybe they black list them if there both the same shouldn't both work ?

And I was complaining so much. Dang sorry. It was worth the wait.
[Samsung Galaxy S22 Ultra] Venom0642:
Yes correct
[Samsung Galaxy S22 Ultra] Venom0642:
Well definitely the battery life on this beast is outstanding over 11hrs SOT
[Samsung Galaxy S22 Ultra] Jobudden:
Not for me. I get like 7 lol
[Samsung Galaxy S22 Ultra] Phariex:
Hi all,

Anyone have the full firmware for the SM-S908U from VZW with the UserData file included?, I downloaded the firmware from the post #3 but only includes the firmware without the UserData file for VZW. The only one I found is the SM-S908U1 for VZW but I will like to have the carrier firmware.

Thanks!
[Samsung Galaxy S22 Ultra] Jobudden:
All Carriers and non carrier have the same version if I'm not mistaken. Your bloat is installed based on your sim. So just download the one in post 2
[Samsung Galaxy S22 Ultra] crispy1805:
Individuals have flashed and fixed the RCS issue on ATT. It appears regular flashing and dirty flashing has worked.

I haven't tried it yet, but given ATT's response yesterday, I may.

'Thank you for reaching out to us with your questions and feedback. RCS is a very exciting technology and we want to ensure it is working for everyone.

To answer a lot of the questions on this thread, let me provide some details about the RCS rollout and functionality.

AT&T and Google are working hand in hand to bring RCS interoperability among providers and clients as soon as possible.

AT&T is not restricting functionality or access, but interoperability is not completely rolled out at this time.

AT&T customers with an RCS capable device on the AT&T network can use RCS messaging between other AT&T customers with an RCS capable device on the AT&T network, as well as T-mobile customers at this time.

Regarding @balkie's question specifically, here are the details.

If a customer has previously downloaded the Google Messages application and enabled RCS, it has utilized the Google RCS / Jibe network.

If a customer uses the featured Google Messages application on the Samsung GS22 series, it is utilizing the AT&T RCS network.

We apologize there is confusion about RCS, and hopefully this helps resolve some of the more common questions. We appreciate your patience and are excited to bring more RCS interoperability in the very near future.

Thanks

Tim, AT&T Community Strategy"

[Samsung Galaxy S22 Ultra] dj24:
Incredible.. I'm just waiting for your patent to run out so you can be forced to share with everyone how you manage to achieve this all the time 🤣
[Samsung Galaxy S22 Ultra] kangi26:
Typically the actual firmware released by VZW and ATT are REALLY REALLY hard to get ahold of. They don't play well with others and don't like to make them available. Sometimes we can get lucky, but most of the time we can ID their latest releases that matches a different carrier
[Samsung Galaxy S22 Ultra] itsLazR:
A little annoying they couldn't have fleshed this out *before* shipping it standard with S22 but at least they finally made a full official statement about it. I guess I am going U1 firmware when I get my phone this weekend
[Samsung Galaxy S22 Ultra] MidtownHD:
T-Mobile messed with the t-mo branded version of S21 and its firmware where even if you flash the U1 version you're still stuck with TMB/TMB/TMB. Not sure if they did anything to the S22 series. It's still better to get it from Best Buy because they sell the XAA version.
[Samsung Galaxy S22 Ultra] kangi26:
It will always show that based on your SIM card and these items AP/CP/CSC
[Samsung Galaxy S22 Ultra] MidtownHD:
Not true, I'm talking a specific issue to the t-mobile version of S21; because in the past you can swap u/u1 and carrier firmware.
[Samsung Galaxy S22 Ultra] kangi26:
Sorry, I got my eyeballs stuck on the TMB/TMB/TMB part of what you said and didn't see anything past that :D
[Samsung Galaxy S22 Ultra] Kris_b1104:
Does it matter if I flash U1 firmware with USC or XAA CSC?

I'm on AT&T locked U firmware, Snapdragon 512gb.
[Samsung Galaxy S22 Ultra] lokofly:
So I flashed U (ATT) on my U1, but I wanna go back to test some things out. I flashed U1 but under the service provider software version: im still getting ATT/ATT, ATT/XAA. Anyone know how I can get it back to XAA/XAA, XAA/XAA?
[Samsung Galaxy S22 Ultra] Markeee:
Interesting I'm on a US Factory U1 phone running stock factory U1 firmware with Xfinity mobile sim and T-Mobile eSIM my software version is showing TMB/CCT/TMB/XAA no complaints all my carrier services are locked in solid and fairly bloat free no carrier mess. What do you think straight up XAA/XAA, XAA/XAA will get you I don't even think you can get it I think if I'm not mistaken from previous flashing as soon as u install the carrier sim it pops back to some combination if XAA an carried ?
[Samsung Galaxy S22 Ultra] hand-filer:
What humor?
[Samsung Galaxy S22 Ultra] efrancis1409:
Not sure if anyone will know but when can we expect these firmwares to be available? Pre ordered S22U from AT&T and plan on immediately flashing unlocked firmware on to it.
[Samsung Galaxy S22 Ultra] FernBch:
Any recommendations for Hiemdall for Linux?
[Samsung Galaxy S22 Ultra] kangi26:
A few weeks? Maybe? It can be very hard to say. But as soon as they are, we'll have them listed here within a day or 2
[Samsung Galaxy S22 Ultra] mvjunkie:
So once the firmwares start rolling out, it should be just like flashing on the S21 series right? Just as long as your using offical software and not downgrading?

Also pardon my not knowing, for the first time in a long time I bought a Verizon S22 Ultra for the 1k trade in promo. There is no difference between the versions ( In the US ) in regards to what LTE and 5G signals they can receive? I usually buy unlocked but couldnt pass up this deal. I dont want verizon disabling bands in case I want to switch carriers and or/use dual sim - nano and esim.

Thanks
[Samsung Galaxy S22 Ultra] kangi26:
I would suspect the flashing will be similar, but we'll know FOR SURE when we have the devices in hand and can mess with them a bit. I'd be surprised if there was any differences.

You shouldn't have any issues if you want to change carriers with the bands. As long as you can have the carrier unlock it of course
[Samsung Galaxy S22 Ultra] Markeee:
Just wondering if there's any particular reason you recommend using the older version of Odin3_v3.13.3b when there's a newer Odin3 v3.14.1_3B_PatcheD been for out already for a long time below link?

Patched Odin 3.13.1

For those looking for a modified, modded, or patched odin that is a newer build than all the fake and renamed prince comsy 3.12.3 versions floating around. I patch recent Odin versions to offer similar functionality to the princecomsy; in that...

[Samsung Galaxy S22 Ultra] kangi26:
I've never had any experience with the newer version, so I posted the one I know worked previously. If the newer patched version works, well, we'll add a link that one :D
[Samsung Galaxy S22 Ultra] Markeee:
Yeah i was told by the op developer that the newest version is the best one to use. I've personally been using it for over a year and its works fine never had a problem. The older version is out dated already best to go with the newer one I would think.

I am having a hell of a time trying to flash my S22 Ultra unlocked with TMO firmware! I am not new to this, but I have been away from the game for a minute, any help would be greatly appreciated! My issues thus far have been finding the firmware that actually will download for U and U1, then running into SHA256 error in Odin. Thanks in advance!
[Samsung Galaxy S22 Ultra] southern87:
Use the Odin in the post #2 and 3. The 3.14 or whatever doesn't work. I tried it for ****s and giggles when I got mine and I got the same error.

Post 2 has the firmware for Tmobile. It is for a few carriers as they are bundled into it.
[Samsung Galaxy S22 Ultra] Kris_b1104:
Make sure you are using the correct usb-c cables and try using different USB ports on your laptop/computer. I got that SHA256 error one time and when I tried the other USB port it worked fine. Also, as someone mentioned, use the Odin and firmware link in this thread.
[Samsung Galaxy S22 Ultra] borijess:
I have an ATT carrier locked phone the U version. Can I flash the Unlocked firmware? If I decide to go back to carrier locked once a fix for the lag and battery isssues is resolved?
[Samsung Galaxy S22 Ultra] Kris_b1104:
Yes you can flash the unlocked firmware, and yes you can go back to locked U firmware.
[Samsung Galaxy S22 Ultra] borijess:
If I stay on Unlocked firmware. Do I get those updates?
[Samsung Galaxy S22 Ultra] Kris_b1104:
You will get U1 unlocked firmware updates if you are on an unlocked firmware. You will receive U locked firmware updates if you are on locked firmware. Normally, carrier locked devices get updates first, then it is released to unlocked devices.
[Samsung Galaxy S22 Ultra] kangi26:
Cool thing is (As of now) the U1 build is aligned to all carriers, so anyone on U1 now will get OTA
[Samsung Galaxy S22 Ultra] Kris_b1104:
Wait what. I'm on U1, will I be receiving OTA AT&T U Firmware updates? I assumed I would be receiving U1 OTA updates because that's how it was before.
[Samsung Galaxy S22 Ultra] borijess:
I am on my second phone. Both had similar issues. Do you think flashing the U1 version will fix the issues. I find it hard to believe I received to bad phones.
[Samsung Galaxy S22 Ultra] KOLIOSIS:
Try this (tap on the link for details) :

https://xdaforums.com/t/ota-and-non...ltra-sm-s908u1-versions.4400511/post-86487997
[Samsung Galaxy S22 Ultra] kangi26:
No you will NOT get U OTA if you are on a U1 firmware, they are not related in any way. You will receive U1 OTA.

It can be confusing (I try to make the distinctions) there are the Carrier Firmware (U) and then the carriers, (related to both U and U1 firmware). Each carrier is associated with both the U and U1 firmware and to get OTA you must be on the carriers build on either U or U1 firmware. It's a little hard to describe since we only have 2 available right now.

So as an example with the Note 20Ultra U firmware below. If your carrier was ATT and you flashed the EVA9 Firmware you would not get OTA

N986USQU2EVA9 TMB/SPR/USC

N986USQS2EULI ATT/CCT/CHA/SPR/TMB

If you were on the U1 firmware N986U1UEU2EVA9 (Notice this is different than the EVA9 "U" firmware naming), you would get the U1 OTA because all of the Carriers are using this same build number for U1.
[Samsung Galaxy S22 Ultra] jones791:
Thanks for the information. I will go this a go when I get off duty.
[Samsung Galaxy S22 Ultra] jones791:
Thanks! I have tried multiple times to get the firmware in this thread to download with negative results, thoughts on that? It either errors or says no mirrors found?
[Samsung Galaxy S22 Ultra] kangi26:
AFH can be a pain, are you on phone or PC?
[Samsung Galaxy S22 Ultra] jones791:

[Samsung Galaxy S22 Ultra] srefvrg:
Does anyone know if the auomatic CSC changing feature works after flashing U1 firmware on a carrier device? Seems like One UI 4 broke it for the S21 series and it was never fixed.

Hey I got it flashed finally! Thanks for all the responses, much appreciated!
[Samsung Galaxy S22 Ultra] FernBch:
Ok, "not a noob question". Lol

Been a while since I've done this so I need to ask for a memory refresher.

Doing this in Linux with Heimdall.

So far I have:

Downloaded the U1 firmware.

Extracted it with 7zip and created five "tar.md5" files.

Created 5 folders, AP, BL, CP, CSC, and HOME_CSC.

Renamed each file by removing .md5 and extracted each .tar to the appropriate folder.

Here's my question. I'm flashing a Verizon S22U from SM-908U to SM-908U1. Which CSC do I use? CSC or HOME_CSC? I don't care if it wipes user data or not. If it doesn't I'm wiping anyway as I want a clean install.
[Samsung Galaxy S22 Ultra] maddoggin:
this is the definition of a noob question but either way, if you're going from u to u1 or u1 to u i would recommend a complete wipe and for that all you need is the csc file
[Samsung Galaxy S22 Ultra] maddoggin:
No biggie! That's why we're here, too help noobs with noob questions and senior members who've been away for a while with noob questions! ✌️😅
[Samsung Galaxy S22 Ultra] kangi26:
You don't need to worry like we did in the past about bricking. The only real thing to be concerned with is unplugging the cable in the middle of flashing.

Like maddoggin said, you do want to let it wipe. So flash the CSC and USERDATA files (Not the HOME_CSC)

I can't speak about the use of Heimdall, but with Odin you do not extract the individual files (AP/BL/CP etc). They are left in the file format that they come in.

I want to make sure that if someone else reads this, that they dont think that they need to follow your procedures with Heimdall when they are using Odin.

EDIT*** Let us know how it goes for you. You're the 1st person that I'm aware of that is flashing this device using Linux
[Samsung Galaxy S22 Ultra] D.W.H:
Just a quick question. I downloaded and flashed the U1 firmware. If I download the U firmware that is in post #2, will it show the AT&T logo upon boot or no logo at all? Just curious...
[Samsung Galaxy S22 Ultra] iBowToAndroid:
It will show the logo of whatever your Service Provider Software Version is configured to
[Samsung Galaxy S22 Ultra] D.W.H:
Ok, cool deal. Yea mine is an AT&T version, so I'd imagine it will show the AT&T logo. Just wanted to make sure. Thanks.
[Samsung Galaxy S22 Ultra] borijess:
So I flashed the U1 on my ATT U phone. The phone is running better and wireless is charging but slowly. Some lag with fingerprint, but not as bad with the ATT firmware. Not sure what the issue but hope they fix battery drain and lag with software fix.
[Samsung Galaxy S22 Ultra] mojicacarmelo:
Anyone got the s22 at&t variant theres an app called "at&t essential" first time i see that app but i cannot find information anywhere about what it is or what it do the icon is like a blue calculator. (just trying to figure out what it is or what it do before i ADB and remove it" 🤔
[Samsung Galaxy S22 Ultra] borijess:
I still might return this device. My note 20 ultra runs so much better. We should not be dealing with a lesser experience with a newer device. I do not want to settle on crap.
[Samsung Galaxy S22 Ultra] FernBch:
Good point!

Since I am a Linux user none of what I'm asking and going to do applies for anyone using Windows/Odin.
[Samsung Galaxy S22 Ultra] FernBch:
Ok. As I thought, I was over thinking things, as usual. Seens things have evolved since last doing this. Heimdall now has a front end for Linux. No more doing it from the command line. I know what I'll be doing soon. I'll let you know how it goes.
[Samsung Galaxy S22 Ultra] borijess:
The adb disable GOS has given the phone life again.
[Samsung Galaxy S22 Ultra] Kris_b1104:
Would you mind explaining in steps how you did it with ADB control app? I've never used it before but it seems simple, I just don't want to mess up.

[Samsung Galaxy S22 Ultra] cafonez:
Question for all Tmobile Ultra S22 owners that got theirs from Samsung Unlocked and are in a 5G UC area. Is it worth it to flash the carrier firmware for the 5G UC icon? Honestly, it's driving me a bit crazy not seeing it. After multiple tickets with Tmobile, they finally did something to the 5G tower across from me and I got 500 down today even though it said 5G. (Short story, My S21 Ultra always said 5G UC)

Does the carrier firmware force it to lock on to a tower better than non-carrier firmware?
[Samsung Galaxy S22 Ultra] kangi26:
From the other posts I've read here, it makes no difference
[Samsung Galaxy S22 Ultra] kvell36:
There's no real difference between carrier and unlocked, they both have the same CSC. The only difference is that the carrier version gets some network features earlier (e.g. 5G SA on S21U TMB) but sometimes it's a good thing not to get those features immediately. 5G SA resulted in dropped calls for weeks for me and I switched to unlocked firmware to get rid of it. Something to note is my unlocked fw S21U was consistently pulling 750+ Mbps on tmo 5G but my S22U on unlocked firmware and TMobile firmware is only getting about 660. Not something that'll make a difference day to day but seems the antenna needs some tuning.
[Samsung Galaxy S22 Ultra] FernBch:
Well, so far the Linux/Heimdall thing is not working. I can detect the device but when I try to read the PIT the handshake doesn't get sent. Looks like I need to do some troubleshooting. My Linux distro is giving errors when I try to update so I need to fix that first.
[Samsung Galaxy S22 Ultra] FernBch:
Question. The file linked for the U1 firmware. Is the file name in the proper format? In Heimdall, using the front-end in Linux, it looks just like Odin. All I should have to do is navigate to that location and flash it. Problem is Heimdall doesn't see it.
[Samsung Galaxy S22 Ultra] Jobudden:
I'm surprised it's taking so long for an update
[Samsung Galaxy S22 Ultra] FernBch:
Progress!
