[Samsung Galaxy S23 Ultra] rumplebuttskin:
No, my situation is a just little bit tangled. I've been using a regular orange SIM with a FirstNet account, because my A52 5G (U1) worked very poorly with the black SIM when I got it 2 years ago (terrible call quality, slow data). I had tried to flash that phone with U firmware when I got it, but it didn't take and I gave up. But the orange SIM has worked well, although I have no clear idea about which FirstNet network features I've been missing out on (Band 14, etc.).

So today I flashed the new S24 Ultra 1TB with AT&T-locked firmware, booted it up with the orange SIM in it and saw the AT&T splash screen, calls and data are working well. I then went into the AT&T store to get a black FirstNet SIM, which I figure should work perfectly now. But when they scanned the phone's on-screen barcode at the beginning of the process of programming the SIM, they said it was coming up as a non-FirstNet-ready phone, despite the model number appearing on the list of eligible devices.

I don't know enough about carrier/network tech to know why this would happen. Could it be because the IMEI shows it to be the 1TB model, which AT&T doesn't sell and is not listed as FirstNet-ready? Or maybe it really is just too early and even a 256 or 512 GB S24 would likewise be rejected for a new black SIM until official release day. (I assume that an existing black SIM would work fine, but I don't have one.)

I'll go back in there next week, and probably also call FirstNet and see what they say about it.
[Samsung Galaxy S23 Ultra] butchieboy:
Unfortunately I couldn't get anything to work with my Firstnet Sim. Device boxed back up and sending it back tomorrow. Will just order At&t version
[Samsung Galaxy S23 Ultra] bassman418:
So does the 5G look different now or is it just me?

And not the inverted color mode, that's normal. I'm talking about the size and or shape of it. I remember it not being in a box I think. I just don't have any screen shots of it prior because I normally have the top bar off in the screen shot menu.
[Samsung Galaxy S23 Ultra] jdk2:
Might it have something to do with the background image?? Don't know.

Venom we need to talk🤣🤣🤣
[Samsung Galaxy S23 Ultra] bassman418:
Pretty sure I follow her on Instagram. Or some one that looks like her twin :LOL:
[Samsung Galaxy S23 Ultra] borijess:
I have ATT. Will this continue to give me OTA updates from ATT?
[Samsung Galaxy S23 Ultra] borijess:
Did you order your phone from ATT directly? Or Samsung? I am still waiting from ATT.

Thanks for the quick response @Venom0642 I will be flashing this right out the box.
[Samsung Galaxy S23 Ultra] butchieboy:
I pre ordered from At&t had mine in 2 days
[Samsung Galaxy S23 Ultra] butchieboy:
If you are on a At&t locked U device in order to get Ota you will have to stay with the firmware that At&t releases. Although you can flash any firmware from any carrier, if the firmware is different from At&t update path you will not get OTA. This means you would have to flash back to the build number that At&t was on. Sometimes this is difficult because At&t does not post their firmware. If you have a locked U device and flash unlocked firmware, U1 you will get U1 ota
[Samsung Galaxy S23 Ultra] Venom0642:
AT&T
[Samsung Galaxy S23 Ultra] GroovyGeek:
Getting my ATT device today and wanted to clarify. The above applies only if I flash another vendor's U software on a ATT device. If I flash the U1 firmware in the OP then I can still get U1 OTA.

From what I have read U1 OTAs may come slower than U OTAs on ATT, is the delay meaningful? I don't care about a week or two, and would prefer to remove ATT crapware without rioting.
[Samsung Galaxy S23 Ultra] borijess:
I preordered mine on the 10th. Still says will ship today but no tracking number. I have a feeling it will be delayed.
[Samsung Galaxy S23 Ultra] butchieboy:
OK I will give example. Let's say all the carriers release a security update. Say all the carriers except At&t are S1DFRT and At&t is S1DFRU. You can flash the S1DFRT but in order to get OTA from At&t you would need to be on S1DFRU. I only used these characters as an example
[Samsung Galaxy S23 Ultra] peacey8:
Which CSC are you on?
[Samsung Galaxy S23 Ultra] peacey8:
@bassman418 That's the firmware files which have all CSCs. It doesn't show what CSC you're on. Go to settings -> About phone -> Software Information -> Look at Service Provider Software Version. What does the second line say?
[Samsung Galaxy S23 Ultra] borijess:
Anyone have instructions on how to install the firmware on a Mac using Odin?
[Samsung Galaxy S23 Ultra] jcsww:
AT&T likes to flag devices not sold by them based on the serial number and IMEI to encourgae you to buy your device from AT&T by restrict the features available to those devices. I wouldn't be surprised if this applies to FirstNet SIM's as well.
[Samsung Galaxy S23 Ultra] butchieboy:
I shipped it back today and ordered the At&t version..delivery February 28th..crying...lol
[Samsung Galaxy S23 Ultra] rumplebuttskin:
That's too bad. Did you flash it with ATT-locked firmware, and it still wouldn't work with your existing FirstNet SIM?
[Samsung Galaxy S23 Ultra] butchieboy:
Naaah, just shipped it back
[Samsung Galaxy S23 Ultra] bassman418:
I ordered my wife's S24+ unlocked from Samsung. Hopefully it's not a problem on my Verizon account. I plan on just slapping her sim card in it.
[Samsung Galaxy S23 Ultra] butchieboy:
The main issue has to do with Firstnet sim in unlocked device. Their device support page says they do not support unlocked devices
[Samsung Galaxy S23 Ultra] rumplebuttskin:
Yes, it definitely does apply to FirstNet, but the IMEI block can be circumvented. Firmware ineligibility cannot be circumvented.

For future reference, to anyone interested: my new and improved understanding of the FirstNet device eligibility system, after reading a lot of anecdotal evidence from other people's experiences, is as follows.

The AT&T/FirstNet network doesn't have a whitelist or blacklist fine-grained enough to block IMEIs that aren't supposed to be on FirstNet. The IMEI roadblock is erected at signup, and that's what I ran into. (I'm now pretty sure that my S24 was rejected because its IMEI is inalterably categorized as a U1-firmware device, even though I'm running AT&T-locked U firmware on it.)

However, if you can get your hands on a working FirstNet SIM card (no matter what IMEI it's supposed to be associated with), and if you're running AT&T-locked firmware of a model number that is listed by FirstNet as FirstNet-ready (e.g. my SM-928U), then FirstNet should function fully.

So, it's possible to use an existing FirstNet SIM from another phone, or to register for FirstNet with any IMEI from any eligible device and then turn around and put that SIM in a flashed phone that fits the description above. The network doesn't care if they don't match.

In the end, I actually decided not to even try that workaround. Ran into too many complaints of network problems exclusive to FirstNet, like messages not being recieved, photos being downsized, etc., and heard of customer service in some cases even recommending users move to an orange AT&T SIM to fix it. But everyone says that AT&T has now stopped allowing orange SIMs to be activated for FirstNet accounts, so I'm keeping my head down and clinging to my orange one, since it works well in all the important ways. Pretty lame that AT&T chose not to offer the 1TB S24, the extra storage is necessary for my work and it's the only reason I had to mess around with all this.
[Samsung Galaxy S23 Ultra] lowkey74:
Placed my order on Friday @ 1130am est. I'll have my at&t 24 ultra in black on Monday. See y'all on the other side.
[Samsung Galaxy S23 Ultra] butchieboy:
Since I sent my U1 model back and re-ordered, it says my delivery date is February 28th😭
[Samsung Galaxy S23 Ultra] yeltrah123:
AT&T is a pain the butt to deal with for unlocked Android devices. I remember back during the release of the S20 series my unlocked S20 Ultra got flagged, and I couldn't get mobile hotspot and wifi calling to work. I had to get the device reprovisioned and had to flash the U carrier firmware to finally get it to work. Idk why AT&T's systems are very stingy.
[Samsung Galaxy S23 Ultra] jcsww:
AT&T does this on purpose to encourage customers to only buy devices from them.
[Samsung Galaxy S23 Ultra] yeltrah123:
Yeah sucks tbh. Interestingly, iPhones don't have that issue.
[Samsung Galaxy S23 Ultra] bassman418:
So, have any new pages been created yet? 😁😉
[Samsung Galaxy S23 Ultra] butchieboy:
My pre oder has been moved to February 28th to March
[Samsung Galaxy S23 Ultra] lowkey74:
Ouch. What color did you choose?
[Samsung Galaxy S23 Ultra] butchieboy:
Grey 512 GB At&t. Samsung told me At&t devices are back ordered. So pre order served no purpose
[Samsung Galaxy S23 Ultra] lowkey74:
I placed my order through AT&T last Friday morning and had my device by 1pm on Monday. Got mine in black 512 GB.
[Samsung Galaxy S23 Ultra] butchieboy:
I pre ordered through Samsung
[Samsung Galaxy S23 Ultra] butchieboy:
Didn't go through At&t because I try to stay away from installments
[Samsung Galaxy S23 Ultra] Venom0642:
February patch got it early this morning.

AT&T S23 Ultra U1
[Samsung Galaxy S23 Ultra] borijess:
Same
[Samsung Galaxy S23 Ultra] jcsww:
Got mine for the U1 firmware yesterday on T-Mobile.
[Samsung Galaxy S23 Ultra] yeltrah123:
I returned the S24 Ultra
[Samsung Galaxy S23 Ultra] warriorvibhu:
I am not happy with the Ultra screen and want to return any thoughts you guys.
[Samsung Galaxy S23 Ultra] zoman7663:
Upcoming firmware update is "supposed" to have an adjustment for vibrancy. So, it can be turned up a notch or two. I'm not sure if that is why your unhappy with the screen or not but that is what I have seen. Personally, I think it's less vibrant than the S23 Ultra I just traded in but not bad (to me) by any stretch of the imagination. I am looking forward to being able to adjust it though.
[Samsung Galaxy S23 Ultra] butchieboy:
I keep reading that it will be fixed and it will not be fixed. Not sure which is true
[Samsung Galaxy S23 Ultra] warriorvibhu:
Exactly the lack of information and abundance of misinformation is crazy out there.

I do feel its not fixable as this seems to be caused by the anti reflective coating unless they drive the vibrancy quite a bit up.

Well not just the vibrance also the graininess and people getting those bars. i just wish I dont get that issue no one wants to be running around getting warranty replacement and setting up the phone again and again given that i have 400 GB of stuff (and no pics and videos are not taking up space)
[Samsung Galaxy S23 Ultra] butchieboy:
Anyone have a link for a good YouTube Vanced or Revanced? All mine does is buffer constantly after about 30 seconds of playing
[Samsung Galaxy S23 Ultra] Venom0642:
Here i builted myself with ReVanced Extended, Patches they released it.
[Samsung Galaxy S23 Ultra] ekerbuddyeker:
I'm not unhappy with it, but I feel like I own the same phone again, with slight improvements and a bunch of gimmicks i won't use.
[Samsung Galaxy S23 Ultra] warriorvibhu:
Did I just read the two posts above me right ?
[Samsung Galaxy S23 Ultra] yeltrah123:
Yeah that's the reason why I returned it, also I've been having issues with dual Sim.
[Samsung Galaxy S23 Ultra] butchieboy:
Mod can you delete the dating crap
[Samsung Galaxy S23 Ultra] warriorvibhu:
Really? I got to check this, i havent had time yet but today will surely put another sim and check.
[Samsung Galaxy S23 Ultra] yeltrah123:
Yeah it works but performance takes a big hit, I saw some other folks having the same issues.
[Samsung Galaxy S23 Ultra] warriorvibhu:
I didnt get a chance yet again due to the snowstorm keeping us New Yorkers busy.... Hopefully today will check...
[Samsung Galaxy S23 Ultra] butchieboy:
Does anyone remember dialer code to check for updates?
[Samsung Galaxy S23 Ultra] Venom0642:
*#8736364#
[Samsung Galaxy S23 Ultra] yeltrah123:
Cool, I'm from NY too lol.
[Samsung Galaxy S23 Ultra] warriorvibhu:
Well i am hoping you didn't have to shovel like me ... Meanwhile i did try using another sim but Verizon devices are locked and even if fully paid they don't unlock before 60 days so seems i have to wait till then.
[Samsung Galaxy S23 Ultra] davidzeb:
Flashed my Samsung Galaxy S23 Ultra SM-S918U to SM-S918U1 with patched Odin. It was originally a VZW CSC and I'm trying to get it to XAA... but I've done this twice now with the regular CSC file, not HOME_CSC. And both times it comes back up with a VZW CSC. I've also downloaded the firmware from different sources both times. One from Frija and the second from samfw.com.

The phone has come back up wiped to defaults each time, and the model number is showing SM-S918U1 now.... just still VZW and I'm unable to modify APN settings on my esim. Verizon splash is also gone, so I'm running the stock firmware.

Any ideas on what could be going on here?

Thanks!
[Samsung Galaxy S23 Ultra] yeltrah123:
I used the SamFW tool to change CSC before flashing locked U to U1 https://samfw.com/blog/samfw-frp-tool-1-0-remove-samsung-frp-one-click
[Samsung Galaxy S23 Ultra] warriorvibhu:
Does it change all three CSC - like TMB/TMB/TMB to XAA/XAA/XAA

Ok i tested on my S23 and i can see it doesnt change all 3.
[Samsung Galaxy S23 Ultra] yeltrah123:
Yeah it doesn't change all three. That's because the last one will indicate the original csc. However, it's great since you can convert the CSC to XAA so you can be able to flash the U1 firmware with no issues.
[Samsung Galaxy S23 Ultra] davidzeb:
From what I've seen, changing the CSC like this will prevent OTA updates, right? Does it cause any other issues?
[Samsung Galaxy S23 Ultra] warriorvibhu:
i have changed CSC and still received OTA updates in the past with my Note20 Ultra and S23 Ultra.
[Samsung Galaxy S23 Ultra] yeltrah123:
Nope, the device will still be able to receive software updates via OTA.
[Samsung Galaxy S23 Ultra] teknomedic:
I'm sorry for the silly question, but just want to get clarification.

I have a USA Verizon S23 Ultra (bought directly from Samsung, Verizon boot sequence). When I look at "about phone" it reports Model SM-S918U and Hardware Rev 1.0

If I follow this guide by flashing the firmware can I ultimately get an unlocked bootloader and root my S23 Ultra??

Thank you and any information about this.
[Samsung Galaxy S23 Ultra] butchieboy:
No, not from here. This is just a guide on how to flash stock firmware. There is a service for unlocking bootloader but as of now it is on hold. I will send you a PM with the information you need.
[Samsung Galaxy S23 Ultra] borijess:
Do we have this type of thread for the S24 ULTRA yet?
[Samsung Galaxy S23 Ultra] maddoggin:
Second that!
[Samsung Galaxy S23 Ultra] OnnoJ:
What is holding you back...😉
[Samsung Galaxy S23 Ultra] teknomedic:
I appreciate that, thank you!
[Samsung Galaxy S23 Ultra] butchieboy:
I thought about doing it. But even At&t has been good about posting firmware on Samfw. So really didn't think that it was needed. Question to all of you regulars here. If I do decide to do it, maybe I can keep this group as is but add S24Ultra to main thread. Or do you think people would get to confused?
[Samsung Galaxy S23 Ultra] butchieboy:
Forget that idea, it would be a mess and not sure XDA would allow it
[Samsung Galaxy S23 Ultra] borijess:
So where is the firmware if you have a ATT locked S24 ultra and want to flash unlocked firmware?
[Samsung Galaxy S23 Ultra] butchieboy:
Ummm right here. Been posted for ages where to get the firmware

https://samfw.com/firmware/SM-S928U1
[Samsung Galaxy S23 Ultra] butchieboy:
Samfw
[Samsung Galaxy S23 Ultra] bigron77:
I'm sure people would get confused. I have both devices (also on ATT) so I like the idea of everything in one spot. But, unfortunately folks just don't read or utilize the search option. Either way, I appreciate the effort you put into this one. Thanks Bro
[Samsung Galaxy S23 Ultra] butchieboy:
Thank you my friend. I'm so busy with work and family these days, working 5am to 5pm I don't have time for much.

[Samsung Galaxy S23 Ultra] Hunt4m3x:
Is there a certain order that is needed to be flashed for Android 14?

My phone is stuck at S918U1UES1AWC9 and I just realized it. Check for software update fails and I already cleared the cache so was going to manually apply the updates but I didn't know if there is a certain upgrade path to follow.
[Samsung Galaxy S23 Ultra] bigron77:
I'd recommend that you download the latest firmware (U/U1), perform a factory reset and flash the ROM files with Odin, to avoid future errors or unexpected behavior.
[Samsung Galaxy S23 Ultra] darthmalus:
It’s been awhile since I’ve owned a galaxy device, would flashing the U1 firmware nuter the WiFi calling like it did in my old Note 9? I was thinking about swapping my current phone with a S23 ultra.
[Samsung Galaxy S23 Ultra] easyrider77:
So I have a s23 ultra SM-S918U1 meaning samsung factory carrier unlocked.

So the problem I'm running into is, there is no oem unlock toggle in dev settings. So I read the first post it didn't mention anything about toggling that. Since the phone is already carrier unlocked do I need to still toggle the oem unlock switch or can I just bypass that step, and go to recovery and unlock the BL?

If OEM unlock toggle is needed, how do I go about getting it to show to toggle it on?

UPDATE:

On further checking, I went into About phone > Status Information > and checked the model code. Its showing as SM-S918UZKAVZW. The last 3 letters would signify it's not a "factory" unlocked phone, but rather a vz carrier unlocked phone.

This would also explain why there is no oem unlock available, vz phone can't be rooted as I hear it.

What I'm confused about is the model number is listed as SM-S918U1.

So from my understanding:

-U is carrier branded and can be unlocked via a request from the user to the carrier, to be carrier unlock for the phone to work on any carrier

-U1 is an actual Samsung factory unlocked phone, ie: it's unlocked AT the Samsung factory before going out in public

That's why I got this phone because it was listed as U1 and not U, so I am really really confused now.

If the U and U1 don't matter how exactly do you tell if a samsung phone is truly samsung factory unlocked at the factory as apposed to the carrier side? Maybe someone could give me a better more simplified (lamens terms) break down so I better understand it
[Samsung Galaxy S23 Ultra] dj24:
@butchieboy: Can I have the link too? Just joined the 23 Ultra family with a U1 device recently. Thanks!

Check PM
[Samsung Galaxy S23 Ultra] dj24:
Anyone dealing with intermittent freezing on your home screen once in every while? I just upgraded recently from my S22 ultra and never had this issue on that phone. Not a major concern since it happens very sporadically and lasts very briefly until I lock and unlock the screen or worst case scenario- reboot my phone. I'm still catching up on the S23 ultra thread so if this has been mentioned somewhere and I haven't seen it please feel free to refer me there.. I have a U1 device and am on t-mobile if that matters. TIA!
[Samsung Galaxy S23 Ultra] SuperSHO:
Downloading a 2.8 gig file from AT&T now. I flipped my date to 3/29/24, and he let me start the update. Because of my excitement, I didn't grab the link to share.

guys please help me phone S23 s918u1ueu1awa6 do I need viename firmware where do I find it?
[Samsung Galaxy S23 Ultra] OnnoJ:
There is no Vietnamese firmware for North American S23 Ultra (SM-S918U/U1/W).

Vietnamese firmware can only be installed on SM-S918B/DS.
[Samsung Galaxy S23 Ultra] yeltrah123:
Don't forget to update the Google Play System.
[Samsung Galaxy S23 Ultra] borijess:
The update is out for me. Unlocked software on ATT network.
[Samsung Galaxy S23 Ultra] jcsww:
The OneUI 6.1 update is also available on T-Mobile for the U1 firmware.
[Samsung Galaxy S23 Ultra] dj24:
Guessing no one has similar issues...?
[Samsung Galaxy S23 Ultra] butchieboy:
Hey guess what? There's an update out 🤣🤣
[Samsung Galaxy S23 Ultra] readymarc:
Charging is capped at 15w ...Damn Samsung
[Samsung Galaxy S23 Ultra] butchieboy:
First rule...read read read. This thread tells you what you need to know. If you are that confused about what you can and can't flash you should get a better understanding of what you are doing. I think most here use Samfw for the firmware they need and flash with Odin. If the firmware you need is not posted here, go to Samfw. If your bootloader number has changed in any way you can't flash back. May I ask why you are still on beta when stable is available?
[Samsung Galaxy S23 Ultra] nitink1234:
I was working in a different country so i wanted to check Android 14 and in my country there was no beta software so i flashed it manually. I had flashed till beta 6 and then i just moved back home. I was pretty happy with it so didnt flash the other version since. But now Since 6.1 is a major update wanted to flash it. I have download the stable One ui 14 on my system. But i just wanted to know if it is safe to flash over the beta 6 directly using Odin. I was actually planning to downgrade to 5.1 but using the youtube video i saw which was 7 months, in that video they got android 5.1 and i got the stable Android 14 so wanted to know if it safe. The phone is out of warranty and i am in a different country so was trying to understand if it is safe or not to move from Beta 6 to stable version.
[Samsung Galaxy S23 Ultra] butchieboy:
It's safe but you will have to factory reset. I would recommend that anyway for best results
[Samsung Galaxy S23 Ultra] nitink1234:
ok I am flashing after Odin. I have downloaded the latest firmware.
[Samsung Galaxy S23 Ultra] nitink1234:
It worked perfectly. I didnt have to do a factory reset. The software is really nice. One ui 6.1 so far but i hate the keyboard it still feels two generation behind Gboard with design and speed.
[Samsung Galaxy S23 Ultra] OnnoJ:
To what percentage was it charged when you noticed?

If your battery was already charged to - let's say - 86%, while charging to 100%, it is perfectly normal.
[Samsung Galaxy S23 Ultra] butchieboy:
I'm glad it worked out for you. Remember there are a ton of people here with knowledge if you have any other questions.
[Samsung Galaxy S23 Ultra] yeltrah123:
Quick question. Anyone know if its possible to flash W firmware on U1 S23 Ultra?
[Samsung Galaxy S23 Ultra] jcsww:
Yes.
[Samsung Galaxy S23 Ultra] tpaxadpom:
I had UI 6.1 installed via OTA. Now the colors on the screen are undersaturated. Looks pretty bad. I am using natural (not vivid) screen mode. I have heard they have fixed issues with colors being washout on S24 ultra, so they decided to introduce the problem in S23 Ultra to force an upgrade?

Is there a way to downgrade UI to 6.0 or whatever the previous version was without full wipe and reload?
[Samsung Galaxy S23 Ultra] borijess:
April update out for unlocked Att version.
[Samsung Galaxy S23 Ultra] jcsww:
U1 April update is also available for T-Mobile.
[Samsung Galaxy S23 Ultra] butchieboy:
I hope all is well with everyone. Things have slowed quite a bit
[Samsung Galaxy S23 Ultra] dj24:
Yup.. Still dealing with intermittent freezing issues on my U1 which lasts briefly but goes away. Happens once or twice a week and tends to occur when I take out the S-Pen or when I put a call on speaker and try to retrieve some info or start typing call notes on my calendar. It hasn't bothered me enough to factory reset and start from scratch again since I've seen similar several complaints like mine on reddit and the Samsung community forums where factory resetting hasn't gotten rid of it anyways.
