Flashing a AT&T SM-G988U1 update to SM-G988U USERDATA question - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

My AT&T S20 Ultra has been stuck on the G988USQU1ATBN firmware update. I haven't received any of the new OTA updates and was looking into manually flashing the latest update via Odin. If I were to flash the latest unlocked SM-G988U1 G988U1UES1ATFB update, that I downloaded from SamFirm, to my current AT&T SM-G988U, I would need to use the G988U's USERDATA in Odin to retain AT&T's carrier features like Wifi Calling and VOLTE or is it not possible to enable these features even with the USERDATA on a SM-G988U1 unlocked firmware update? I haven't had any luck finding the latest AT&T G988U update's USERDATA, only the ones from the "G988U and G988U1 Firmware Links and Flashing Discussion Here" topic's U firmware link.
Is it safe to use the ATT Feb 20, 2020 G988USQU1ATAW USERDATA from the U firmware link while I'm flashing the unlocked G988U1UES1ATFB update to my current SM-G988U in Odin? Its my first time flashing a firmware update to a Galaxy phone in Odin.

Help updating to latest update
Could you help me please? I'm so lost on how to use this forum. I've got an sm-g986u on at&t, it's not got an update since June. I'm trying to update it via odin. I don't use a sim card in it as it's not my main phone so I can't get ota updates, and smart switch doesn't work either. I would just throw a sim in it but I guess I bought a blacklisted phone :/ anyway, if I use frija it detects a T-Mobile update for it, but it won't download. It goes for a bit and then drops to zero mb/s. I downloaded the update myself and when I enter the files into oidn, it freezes after I select the cp file and says not responding indefinitely. I just want to get this thing to one ui 2.5. I cannot find any guide for how to do this. Thanks for any insight you can provide. I'm going to try to find a way to make this into a post as well.

g975U1 August security patch ASGF update released

Got notification this morning for a 217mb update ending in ASGF. Pretty weird since we just got the July patch only two weeks ago, after not getting an update in over two months. Definitely not complaining though! Sorry if repost
I don't see that update on my G975U1
I got it too. August US unlocked
Just got the update!
is available via samfirm
Unfortunately i just switched over to carrier firmware for faster updates. Now Samsung finally does it right. At least carriers should be releasing it in a week or two.
Sent from my SM-G975U using XDA Labs
Whats new in this August update?

No idea. There are no details listed on the Samsung website or in the notification popup. I mean the security patch has been brought up to date (August) but other than that, I can't say.
Got the notification today.... Hopefully someone can breakdown what is in the update because 200+mb is rather hefty right?
what sim are you guys using to get this ota update?

U1 updates are released by Samsung. One gets a U1 update as long as one has a existing U1 firmware irrespective of the SIM.

I believe you have been misinformed. Please be patient and wait for the update to show up on your phone if you are already on U1 firmware or download the latest U1 firmware using Frija and Odin flash. All the very best.
Update is due to a exploit in the chip. Some one can take control of our phones if we are on the same wifi. Kudos for the fast update.
I updated and now I don't get icons on my lock screen for notifications. Anybody else have the same problem?
975u1 August Firmware Patch T mobile
Hello,
I have a US unlocked 975u1 and use Tmobile. No one seems to know what I am talking about with an Aug Update. I have spent time on the Phone with Samsung and Tmob customer service. Stuck on July patch ASCB. Night mode is still disabled. Samsung Switch has nothing on it as of this morning.
How do I get the firmware everyone else is on? If I get a sim card from another carrier, does that sim need to be activated in order to get the latest patch? I am clueless here.

U1 firmware with the August security patch and Night mode is available and does end in ASGF.
Unless you flashed T-Mobile firmware on your U1 model or you purchased an unlocked U1 with T-Mobile firmware already installed (I'm not sure how to check that in the settings but U1 firmware doesn't come with any T-Mobile branded apps) you should be receiving OTA updates from Samsung rather than T-Mobile.
The U1 OTA update was pushed weeks ago making it the only OTA update we received before the carriers.
If you have T-Mobile firmware you could flash the U1 firmware manually and receive OTA updates from Samsung but you will lose T-Mobile branded apps that aren't available in the Play Store. The U1 firmware has also been receiving updates long after the carriers prior to August--in early July we were still on the May security patch.
If you manually flash VZW or SPR firmware as the other member suggested don't flash the User Data partition or you will also get Verizon or Sprint's apps and bloatware. If you do manually flash either of those you will no longer receive OTA updates and will need to keep manually flashing updates in the future.
So I bought my phone directly from Samsung. USA version with snapdragon processor and its non-branded to any carrier, basically an unlocked Galaxy S10+. Its model number is sm-g975u1. Sim card is from Tmobile, my cell phone carrier.. I have software from July 1st, g975u1ueu2ASGB
What do you recommend in my scenario.
Thank you

I would look for the ASGF U1 firmware for U1 with Frija or SamFirm. I'm not sure why you didn't get the OTA.

Guys if I flash android 10 again, will system see the next security patch for January

Tired waiting for sprint to send android 10 update.
lame carrier locked.
Use the Frija tool and download the Sprint variant of Android 10.
https://www.sammobile.com/samsung/g...SM-N975U1/SPR/download/N975U1UEU2BSLC/309277/
AFAIK you should still receive OTA updates

Thank you very much, however I am on a locked device and it's a miracle you found a sprint variant even though none reporting they got it on sprint. And the csc says unknown.
I am not ungrateful. I am afraid to flash via odin unlocked variant.
I have firmware N975USQU2BSL7 already of locked devices in the USA but the SPRINT USER DATA MD5 file,. and my query was if i install what I have, when january's patch comes will it update if im on december now. I would not yet try unlocked firmware and thank you for All you provided.

It will still work. The SPR in the ROM stands for Sprint. Check the CSC file to confirm before you flash it but I thought it said SPR. Just flash the ROM using the Odin patched version for it to work.
I am using a AT&T Note 10 with the Star Wars ROM and I just received the Android 10 update earlier tonight. You will still receive the OTA updates but they just might be for the unlocked version if you are okay with that.

For it to get the updates you need to use the CSC that came with the ROM you flash if that makes sense.

I have a question for anyone that may know more than me...
I have an unlocked sprint note 10 plus. Ive flashed it with XAA. So im on unlocked firmware on an unlocked sprint note 10. Im settings my csc shows this... tmk/tmk/spr. Im using metro pcs as the carrier. Where will my updates come from? Using sam info app, it shows the firmware as XAA and active csc as tmk. I have a bunch of avalible csc to use but i dont have the dialer codes with metro. I have inserted a att sim and i have the dialer code to change the csc. However when i put the metro pcs sim in, it goes back to tmk/tmk/spr.
Question 1: With tmk/tmk/spr, on XAA firmware, where will updates come from? Metro Pcs, sprint, or samsung?
Question 2: Are the csc codes tmk/tmk/spr correct being as i am on XAA firmware?
Thanks!

Flash T-mo firmware on unlocked S20 Ultra (SM-G988U1)

Hey all,
I am trying to flash the Tmo firmware onto my unlocked Ultra to get things like the video call option in the dialer, and for the life of me I am getting lost.
I used both Frija and SamFirm to downlad what it said was the correct firmware (SM-G988U1_1_20200312212815_gne8hvb170_fac.zip) putting TMB in the CSC. I flashed that firmware using Odin,
Here is what I did:
Downloaded the firmware (SM-G988U1_1_20200312212815_gne8hvb170_fac.zip) in Frija putting TMB in the CSC box
Unzipped all the files
Flashed them all to the phone in Odin, using HOME_CSC_OMC_OYM_G988U1OYM1ATCH_CL18186338_QB29814488_REV00_user_low_ship_MULTI_CERT.tar.md5 so as not to wipe my data
There is no error, and it finishes successfully, the phone reboots, and there is no change whatsoever.
Am I missing a step here guys?
Thanks so much.
**EDIT**
I finally figured it out.
I needed to flash the TMB U firmware, not the U1 firmware.
Curious do you notice better signal strength on TMO U firmware vs unlocked U1?

Yes you can flash the firmware from an unlocked model. Her is link to what u want. https://www.sammobile.com/samsung/g...e/SM-G988U/XAS/download/G988USQU1ATE6/339775/
yes i have flashed my s20 att to the unlocked version and got the latest june security update yesterday.
So same should apply to your s20 ultra i think.

So here is my issue. I flashed it to the ate6 firmware but I don't think this is the unlocked software. It didn't erase any of my personal info at all. Did I do something wrong?

Yeah,mine did the same, but when I checked my phone info I indeed had the ate6 build.....IDK
You can read thru this thread and it explains word for word how to flash the U1 firmware along with the U CSC of ATE6 and you'll maintain ATT network settings and have June security update :good:

Galaxy S20 Ultra Verizon to Tmobile Flash Help

I have an unlocked, not rooted and factory OS Verizon(SM-G988U) with Android 10. I recently switched to T-mobile and was thinking to flash the firmware from Verizon to Tmobile to better use their wifi calling and other features.
Where can I get the latest files to flash the firmware? Also, to switch from Verizon to Tmobile, do I have to flash Verizon-->Unlocked(U1)-->Tmobile or can I do Verizon directly to Tmobile firmware? I read few threads but I was confused on what exactly I need to do.
I downloaded Odin v3.14.1 and latest Samsung drivers. Beside the firmware files and placing appropriate folders in BL, AP, CP and CSC, anything else I need to do?
Sorry for noob question but this is my first flash and was looking for exact steps.
Thank You
You need to go Verizon-unlocked-Tmobile. You'll want the patched Odin too. I use Frija to get my firmwares https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910584/ but you can use sammobile as well.
Thank You. Is Frija 1.4.3 the latest version?
Also, the Odin I downloaded, the executable says "Odin3 v3.14.1_3B_PatcheD" which I suppose is latest and patched, right?
In the Frija, CSC, I got the Tmobile firmware as TMB. What is the code for the unlocked firmware so I can download it?
Also, do I need to root to flash the firmware from Verizon-->unlocked-->Tmob?
Noyou do not need root
In the Frija, CSC, I got the Tmobile firmware as TMB. What is the code for the unlocked firmware so I can download it?
Never mind found out.
SM-G988U1 , CSC- XAA for Unlocked
and
SM-G988U, CSC- TMOB for Tmobile.
Were you ever able to get WiFi calling to work?
