Just grazing the thread and considering doing an Odin clean install vs factory data reset - is this still the case for the firmwares on samfw? Will the U1 verizon firmware include all the verizon specific bloat? That makes the decision to just factory data reset easy... but is there a basic unbloated U1 (unlocked) firmware that's better to install?
[Samsung Galaxy S23 Ultra] jcsww:
There is no U1 Verizon firmware. The only U1 official firmware, is the non-carrier firmware for the US. Carrier devices use the U firmware but the U1 non-carrier firmware works great with most US carriers.
[Samsung Galaxy S23 Ultra] butchieboy:
Whatever U1 you use the firmware will provision to your Sim without the bloat
[Samsung Galaxy S23 Ultra] miguelrivas:
Good night guys, any idea about updated for this version S918USQU1AWC8? Am still on oneui 5
[Samsung Galaxy S23 Ultra] butchieboy:
Just flash update with odin
[Samsung Galaxy S23 Ultra] chadsawask:
Help please.

OK I screwed up, I bought a s23 ultra from Verizon last year updated to the unlock software. I cracked the screen so it was sent to Samsung for screen in late July, probably on SM-S918U1_XAA_S918U1UEU1AWF3

Meanwhile, changed phones till a few days ago. I put the sim in the s23 ultra I have not touch since july and it says non Verizon sim. OK so at this point I probably could have fixed it. BUT oh no....

Instead and kind of forgetting about what i had flashed up to July last year. I went to the verizon store because i thought i needed a new sim, in this process they updated my phone a lot. I now have to lastest verizon 04/12/2024 CXCN but after the phone is on about 3 mins it still says non verizon sim. same same

I have been trying to flash anything i can, to get it to work.... but odin cominjg back with 0 succeded and phone states on the DL screen an SW issue. I'm down loading off of frija and gonna try that one next. I have also flashed S918U1UES1AWIF_S918U1OYM1AWIF_VZW and S918U1UES2CXCN_S918U1OYM2CXCN_VZW off of sam mobile and also try flashing files from a year ago with the same result. upload has an SW isssue. ODIN zero success

Is there a way to wipe every thing and start over.

What if anything can be done to get this phone working again?

Any suggestions would be great.

Thanks
[Samsung Galaxy S23 Ultra] jcsww:
Are you using the modded or patched ODIN? You are going to want to fully wipe while flashing to make sure you don't have any issues or anything lingering from the Verizon firmware. The nagware is one of Verizon's most well known features.
[Samsung Galaxy S23 Ultra] chadsawask:
Yes I'm using the patch odin from the first page of this thread. I made some progress late last night and was able to flash the file that frija came up with and I was able to get that on the phone. Now it doesn't work even for the 3 mins it used to. So I flashed the latest from sam mobile S918U1UES2CXCN_S918U1OYM2CXCN_VZW and that also succeeded through ODIN. Now I'm back to it screwing up in about 3 mins.... I believe I wipe it every flash. CSC not the home one?
[Samsung Galaxy S23 Ultra] jcsww:
Home preserves data. Never use that, at least in my opinion. If you can sucessfully flash the Verizon firmware. You should be able to flash the U1 XAA. Are you changing any of the default options or leaving them the way they are?
[Samsung Galaxy S23 Ultra] chadsawask:
Where do I get UI XAA file? All the links on page one are broken.

I'm just rebooting through adb and selecting the 4 files in ODIN and hitting start. So I believe that's the default.

Am I going to have trouble, rolling back from the latest firmware? I'll try XAA regardless
[Samsung Galaxy S23 Ultra] butchieboy:
Slow down....what do you mean phone works for 3minutes? What Sim do you have? Do you want carrier locked firmware or unlocked firmware? No reason your device shouldn't work if you are flashing correctly with Odin. I would do a factory reset before trying to flash anything even though you are using CSC in Odin since you have flashed so many different things. Start fresh, I would download firmware from Samfw
[Samsung Galaxy S23 Ultra] seti0070:
Hi everyone, I have a Google Fi S23 ultra with build number Up1A.231005.007.S918U1UES2CXCN on the latest UI version 6.1. I am selling the phone but After factory resetting the phone i discovered that the option for polish language is missing (buyer wants fully Polski). It only lists about 10 or so languages and no option to expand the list on the very first page. Using English and then installing languages and switching results in 50% of the menu items still in English. My question is if there is a firmware version I can flash (Like international) that will give me more language option at first startup after a reset? Also open to other options to fully convert the language. Putting in a polish SIM works fine as far as the cell phone/data service is concerned.

Thanks
[Samsung Galaxy S23 Ultra] chadsawask:
I have tried both Verizon and Unlocked firmwares except XAA, it took over the air updates at verizon store and was still doing the same thing. I insert sim and with in a few minutes it states "non verizon sim" and loses all function non calls,data nothing . IT IS A VERIZON SIM

It hasn't work since i sent it out for the screen last July, but i also had not used it till a few days ago.

I was thinking i had some flaky update installed and when samsung did what ever during screen replacement it was screwed up some how.

Something is a miss, the sim I'm using works in the current phone. Does not in s23 ultra. and didnt before verizon mass update in store.

I'm going to factory wipe phone again and try XAA update.

I had a bunch of problems with odin failing and phone stating SW error....cant extract package bla bla bla. Its seems to have finished the last couple of flashes.

I feel its some type of goofed up provisioning or something
[Samsung Galaxy S23 Ultra] butchieboy:
Hmmm dang. Try going to Samfw and download the XAA firmware. Use patched Odin and I see that you did. Flash the firmware with Sim in device
[Samsung Galaxy S23 Ultra] jcsww:
Make sure the bootloader version is the same or newer than the one your device currently has. You can not downgrade the bootloader, which might be why some flashes have not been successful.
[Samsung Galaxy S23 Ultra] chadsawask:
I have been flashing WITHOUT the sim in it.

Thishttps://xdaforums.com/t/anyone-experience-this-issue.4601515/ seems to be the problem I'm having. but those solutions are not working for me.
[Samsung Galaxy S23 Ultra] chadsawask:
How would i check boot loader version.
[Samsung Galaxy S23 Ultra] jcsww:
Current firmware ends in CXCN. The number before that, which is a 2 in my case, is the bootloader version. That means, the number if I wanted to flash, would have to be the same or higher for a successful flash.
[Samsung Galaxy S23 Ultra] chadsawask:
The phone is currently on... 2CXCN. I believe the problems something happened last June July like mentioned in this post https://xdaforums.com/t/anyone-experience-this-issue.4601515/ and if i try those fixes i have no sim anything because they are bootloader 1 and verizon store updated me beyond these fixes.
[Samsung Galaxy S23 Ultra] butchieboy:
This sounds like something that needs to be worked out with your carrier
[Samsung Galaxy S23 Ultra] chadsawask:
Bought last march, so out of 1 year warranty, do you think Samsung could re-flash it, if i sent it in? Is this something they can do?
[Samsung Galaxy S23 Ultra] megapikachu:
I have a samsung s23 purchased from metro and it's carrier locked, which will be unlocked in a few days. It has the metro bootscreen and some of the apps, and i want none of that, so I'll have to flash my firmware. Can you guys go through the steps i'll list out to see if there will be potential issues:

1. Carrier unlock my phone in a few days

2. Factory reset

3. Download latest version of patched Odin and go to SamFw and download U1 XAA

4. Open up Odin and select the downloaded files and use the CSC_ version

5. Let it complete and restart phone and i'm done??

If I want my phone to be unlocked and be able to use any sim i insert in the future, i'll just keep this U1 XAA firmware? Because I read about how some people will flash to U1 first and then re-flash to a carrier specfic U again. I think this might only be on older phones (i read the older threads) and newer samsung phones can just provision whatever carrier sim i insert without needed to do that anymore, right? thanks!
[Samsung Galaxy S23 Ultra] jcsww:
Flashing does not remove the SIM lock on your device and the device can only be SIM unlocked on the original firmware it comes with.
[Samsung Galaxy S23 Ultra] megapikachu:
tyvm for that reminder. I'll make sure i get SIM unlocked on original firmware before i do any of those steps. Does everything else look correct? Thanks for replying!
[Samsung Galaxy S23 Ultra] jcsww:
Everything else is very straight forward.
[Samsung Galaxy S23 Ultra] megapikachu:
thank you again :) I started researching all this yesterday, so i wanted to make sure i didn't miss anything
[Samsung Galaxy S23 Ultra] chadsawask:
So after a few more flashes, I downloaded the oldest vers 2 vzw software I could and I flashed it with the user data. It worked, was able to stay booted. Factory reset, flash latest xaa software and it's all working good now.

Thanks for all the help everyone. :)
[Samsung Galaxy S23 Ultra] butchieboy:
Glad you got it worked out

@butchieboy I am from India and I have S23 Ultra from USA Verizon carrier and its unlocked since my sim works fine but i get a notification that this sim inserted is not from verizon and some features may not be available.. how do i get rid of this and also.. want to have OTA updates from samsung instead of verizon currently my device is on S918USQS2CXCN .....please advice whatt to do thank you...
[Samsung Galaxy S23 Ultra] cupidsho:
if there is any relevant U1 firmware that i can flash please share the link to download and also patched odin link.

appreciate your support in this thread so far you have been great help to others :)
[Samsung Galaxy S23 Ultra] jcsww:
That's working as intended. Verizon nagware is some of the worst in the industry. Download and flash the XAA U1 firmware from somewhere like SamFW and use the PatcheD ODIN to flash it with a full wipe. If you use the HOME.CSC, you are asking for issues.
[Samsung Galaxy S23 Ultra] butchieboy:

Here you go
[Samsung Galaxy S23 Ultra] jrkruse:
It nags you because you’re phone is probably not carrier unlocked you are just lucky Verizon allows non US sims to work.
[Samsung Galaxy S23 Ultra] bassman418:
Been out of the loop for some time with job change and stuff, but quick non-23 related question. Has there been an S24 Ultra thread created? I tried doing a general search, but didn't come up with anything pertaining to firmware and stuff like this thread and previous one before this.
[Samsung Galaxy S23 Ultra] jcsww:
Have you checked the s24 Ultra forum?
[Samsung Galaxy S23 Ultra] Dziadek Mroz:
Samfm or Sammobile where you can find firmware. I think they did not create a firmware post because it is widely available.
[Samsung Galaxy S23 Ultra] butchieboy:
Samfw is where I go. As above post stated. I did not do an S24 thread because most know how to flash firmware with Odin. I was pointless for me to load the firmware from Samfw, then to my Mega account when users can just be pointed to the correct place to download firmware.
[Samsung Galaxy S23 Ultra] bassman418:
So, has anyone in all their years had a problem of all Samsung pass passwords disappearing (Not populating at all) after setting up your phone? I've never had this happen before. My credit cards are populating, and all of the other most current information, but not a single password. (Like almost 200) And it is years of password.
[Samsung Galaxy S23 Ultra] butchieboy:
Make sure to sync it
[Samsung Galaxy S23 Ultra] bassman418:
Yeah, I made sure all of that was set correctly. I could not get it working. So I started making new ones and logging into stuff and after the third one they all if a sudden populated. It was like something was stuck. Lol all good now. I went of carrier Verizon and flashed U1.
[Samsung Galaxy S23 Ultra] butchieboy:
The Android game has slowed quite a bit. I'm actually thinking about selling a majority of my devices. Root is basically impossible without a Samsung token, and the developer pool has gotten less and less. Most things we needed root for in the past, we no longer need. I know we all love Android, and there are a few of us that like to tinker. Most of the Recognized Contributors I know just don't do much anymore. I'm not around much anymore, but have reached out to someone to keep the thread alive. There are tons of people here with the knowledge to keep things going. So by all means if you find something useful to add here feel free to do so. I was one of the lucky few that was able to bootloader unlock and root my S23ultra. But since then things have come to a standstill. If I find out anything new that's worthwhile I will definitely pass it on but only when I have certain developer's permission. I have recently dove head first into the world of RC Cars..lol
[Samsung Galaxy S23 Ultra] butchieboy:
Just got a S918B..man should have gotten it first time around. Flashed At&t csc zip just like having US version..but I will shut up as to not confuse anyone.
[Samsung Galaxy S23 Ultra] dj24:
Did you lose root on your prior device hence the switch?
[Samsung Galaxy S23 Ultra] butchieboy:
Nope, just wanted to get another. Will pack it away or gift it to family, or sell it

Not receiving updates on my samsung 23 ultra. I'm stuck on UI 5.1. Here is service provider info.SAOMC_SM-S918U_XAA_13_0013 XAA/XAA,XAA/XAU/TMB

Mode :- SM-918U

What could be the cause and solution please? Do I need to change CSC?
[Samsung Galaxy S23 Ultra] butchieboy:
Your Tmobile so just flash latest firmware version with Odin
[Samsung Galaxy S23 Ultra] butchieboy:
My first sentence in beginning of this this thread says "Most know how to flash firmware with Odin" if you go back to the 1st page it explains it.

[Samsung Galaxy S23 Ultra] eshipp31:
Hey whatever happen to the old days of note 4 when we had devs like Ovrdrive and TekkHd
[Samsung Galaxy S23 Ultra] butchieboy:
It's not as easy anymore, and not many developers. The easiest way is going for B devices. Since At&t now supports B devices I switched to those and there is actually development. Just make sure your carrier supports the device. At&t actually has a list of all supported devices. There are a ton of B and F devices they now support. I bought a 918B and Jkruse had a United States csc zip that insured device would work ( Thanks Kruse). As I said it's just not as easy anymore.
[Samsung Galaxy S23 Ultra] eshipp31:
where you buy your B devices from
[Samsung Galaxy S23 Ultra] dj24:
Are all the 4g and 5g bands that at&t supports currently on your B device or did you have to unlock them from the service menu?
[Samsung Galaxy S23 Ultra] butchieboy:
Cell Universal
[Samsung Galaxy S23 Ultra] butchieboy:
After I flashed the US csc. I used service menu just to be sure. I have no issues and all the advance options such as wifi calling, advance messaging. I will probably keep buying B devices from now on. The only problem I have ran into is Quickshare. But it's crap in my opinion. There are also Magisk modules to get things like secure folder working. I'm glad I switch to B devices. So if you can afford it I would go for it instead of paying installments. Good thing is ,they have payment options that are cheaper than installments from carrier.
[Samsung Galaxy S23 Ultra] butchieboy:
Service menu I used..deactivated on carrier devices I believe.
[Samsung Galaxy S23 Ultra] dj24:
^^^ Thanks. I need to figure out if the B version includes all the t-mobile bands as well. Is there a site that does good comparisons between 2 different devices when it comes to radio bands? I wanted to compare my U1 device with the B device to make sure all the t-mobile bands are included in the latter and can be unlocked as well.
[Samsung Galaxy S23 Ultra] jcsww:
You will more than likely not have band 71 on international devices. Whether or not it can be unlocked through the engineering menu and whether it works, if you can, I'm not sure of.
[Samsung Galaxy S23 Ultra] butchieboy:
My Watch 7 Ultra arrived today...love it
[Samsung Galaxy S23 Ultra] Dziadek Mroz:
These watches have one big flaw. If they stand alone and use LTE to stream (let's say music) through buds, they overheat within 30-60 sec. I returned 4 classic, 5 pro, and 6 classic, and looks like I will Ultra too.
[Samsung Galaxy S23 Ultra] butchieboy:
Hmmm I'm listening to Spotify as I'm typing this. Listening on Watch 7 ultra with buds using LTE, have listen to 2 songs and has not over heated

[Samsung Galaxy S23 Ultra] Hydraega:
Hi everyone! I'm really new to this, and new here but I need some advice. I pre-ordered the S23Ultra from AT&T because of a huge discount I was able to get from work. The phone is 100% paid for, so it shouldn't be sim locked. If it is, I know the process for getting it sim unlocked through AT&T. I am under the impression that if I flash U1, I will receive OTA updates from Samsung instead of AT&T. Is this true? I do plan on switching carriers in a few months as I make a plan with my fiancee, and I want to be able to receive updates on the phone, even after I've switched carriers. If I'm not mistaken, if it is the AT&T firmware, I need to have an AT&T sim to get updates, but if I have the U1 firmware, I get updates OTA from Samsung instead. Being as I do not plan on sticking with AT&T I want to make this work. Do I need to simply just flash the U1 file that Venom uploaded here for this to be the case and get OTA from Samsung instead? I'm sorry if this was explained previous, I just want to make sure I am interpreting it right before diving into something completely new to me. Thanks everyone!
[Samsung Galaxy S23 Ultra] iBowToAndroid:
Ever since One UI 4.0, a wipe is not required when going between U and U1 - but you have to make sure you're not downgrading, because then it WILL make you wipe. As long as the 2nd-to-last and 3rd-to-last characters in the 2 versions are the same, you can safely use HOME CSC. For example, you should be able to go from WAx to any other WAx, even if the last digit is different. But going from WBx to WAx would probably require a wipe (although Samsung may change this as time goes on)

Hasn't been doable/available on any North American models (with maybe 3 exceptions in the A series) ever since the days of the S7 and S8

In theory, your CSCs should change automatically when you get the SIM set up - you should see a popup prompting you to reboot to apply new carrier settings

Default "unconfigured" CSC that T-Mo and Metro devices come with, out of the box. If you don't insert a SIM and skip thru all the initial setup steps, the Service Provider Software Version will read as all XAUs. Then when you insert a SIM for the first time, it'll configure itself accordingly. It's almost exactly like how U1 devices are XAA out of the box, and then configure themselves to the first SIM that's inserted
[Samsung Galaxy S23 Ultra] EtherealRemnant:
But how does this work with dual SIM? I plan to run Boost Infinite on the physical SIM and Tello on eSIM and use them both. Which CSC takes priority? Or will it just stick with a generic U1 CSC?
[Samsung Galaxy S23 Ultra] butchieboy:
Yes a factory reset sometimes is required when going between U and U1. It has happened to me several times and many others.
[Samsung Galaxy S23 Ultra] Hydraega:
Does changing from U to U1 change where the updates come from OTA? If I have a sim unlocked, AT&T firmware version, and updates are coming from AT&T, and I flash to U1, do my updates now come from Samsung directly? This is what I am hoping to achieve as I don't plan to stay with AT&T forever, and will be using a different sim in the future.
[Samsung Galaxy S23 Ultra] iBowToAndroid:
That's why there are 2 sets of CSCs, separated by a comma. One is the physical SIM and the other is the eSIM
[Samsung Galaxy S23 Ultra] Kevinf100:

Can confirm can flash using odin 3.14.1 (patched). Couldn't get non patched to work, was giving sha256 mismatch. Was able to use home_CSC, and after flashing was able to remove all Verizon bloat I wasn't allowed to before.
