As a follow up, I was finally able to get mine to update as far as the DUG version, (no DUH yet), by doing the keypad temporary CSC change trick. I had tried that twice previously, but this time it worked. I was on XAR and changed to the XAA channel and got 2 updates. This thread has a link telling how to do it.

Just got my first OTA update since flashing from verizon over to ATT. My phone is on SQU2DUH1 now. It didn't even said what was new.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Yeppers, I'm pulling a new OTA for AT&T right now too. Probably Aug Security patch.

Looks like DUH1 is also dropping for USC.

That one could be a Hex breaker let me know how it goes. 3.1.1 has borked it on the Fold. At that size I'm guessing that is our '3.1.1' update even though it will still be listed as '3.1'' on our phones.

Can switching from U to U1 possibly have any effect on RCS? It was a clean flash and everything but randomly it'll just get stuck on connecting and I have to uninstall then reinstall or clear the cache in my carrier settings
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I've gone between U and U1 a few times and have never had any issues with RCS, or connecting for that matter. Sorry that isn't much help to you
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] adj998:
Well it fixed itself after I flashed DUH1. But I lost all my data because I picked the wrong CSC so it wiped my device :/ but at least it works now lol

Meanwhile over at T-Mobile, we're still waiting for our July 1 and August 1 updates. :mad:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
You could dirty flash DUH1 and when TMB's does finally drop you can flash to it :)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] IamSirius:
Yeah, but I'm a little hesitant about bricking my$1400 phone if I screw it up! :oops:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
There's almost 0% chance that can happen.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
I'm assuming you'll lose your dual sim use in the mean time though right?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I'm not sure to be honest. I want to say no, since it's a TMB carrier thing, it may not be specifically bound to the firmware build per se. But that's an assumption.

If you decide to flash, just make sure that you put the right items in the right place in Odin (BL/AP/CP/CSC) and don't disrupt the flashing (Turn the PC off/disconnect the USB cable etc) You should be fine, Personally I don't even mess with my PC, I let the few min go by and let Odin do it's thing before I use the computer.

You COULD do a dirty flash if you're current firmware isnt too old and you're not going between U and U1(Instructions are in the OP)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] IamSirius:
Well, I trust that you are knowledgeable about these things, but I don't trust myself. Lol.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] znel52:
Technically it is still listed as 3.1 but this is the update that brings us 3.1.1 features. It looks like the Z fold line are the only ones that get the 'official' 3.1.1. Everybody else will stay on 3.1 until we get 4.0.

I was really hoping that the DUH2 t-mobile August update would include the missing directors view camera options..:(
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] hayabusa1300cc:
What is that, do you mean dual Recording? If so I've had that for a while
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
Director's view is different from dual recording where it allows you to switch the different lenses in the middle of the recording and includes other features. I remember it was pushed to the at&t and unlocked version in one of the updates a while back but we through t-mobile never got this specific feature.

Use Director's View and Dual recording on your Galaxy phone

Director’s View and Dual recording let you film yourself and your surroundings at the same time - which is ideal for creating social media content.

Anyone on t-mobile after the latest update having issues with group messaging? I'm on the default samsung messaging app and people replying back to me from our established group messaging thread shows in the individual person's thread instead on my u1 device. I've been confusing the heck out of people wondering why I'm replying to them individually because of this..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Lord_Saren:
I'm having something similar, it seems to be happening when it's an actual SMS and not RCS.

In my case on ATT I am getting a "no subject" looking MMS instead of the actual text message in the group chat. Changing my APN and rebooting seemed to fix it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
I'm not sure if t-mobile has an alternative APN setting other than the one here. I also tried adding an additional APN setting using the 'dun' trick mentioned here in this thread. None of them worked. I've reset my apps and cleared cache from my samsung messaging app as well as wiping my clear partition and rebooting numerous times.

I'm surprised more people here on t-mobile using the default Samsung messaging haven't faced the same issue. Everything was fine until the August update a few days ago. Now all Group messages sent to me are going straight into the sender's individual message thread instead of the group thread. If no one else is facing this issue here the last step is to factory reset my U device which I really hope will not come to that.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] hayabusa1300cc:
On TMB U1 I have no RCS on stock app. I have to use Google messages to get RCS. It's fine because stock message app is going away, and it'll be replaced by Google messages officially.

Noob question and just bought an Ultra, unlocked.

It's been a while since I've flashed a Samsung Note device. Have done it to the 8 and 9 going from carrier to unlocked firmware. This time it's different, going from Unlocked to T-Mobile so that I can have the Esim feature. I have downloaded the patched Odin and also the following firmware, N986USQU2DUH2.

Are the instructions as basic as what's posted in the first post?

What I've always had to look up before was the CSC part. Do I flash the Home_CSC or not. Never heard of the dirty flash before either. I know I attach the BL, AP, CP, but which CSC do I attach? CSC or HOME_CSC? And what about Userdata? Needed or not for a fresh install?

Much thanks in advance!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
So if the device is on an Unlocked firmware, the one you downloaded is a Carrier firmware. I would NOT try to dirty flash. Actually, I don't think you can when going to/from Carrier/Unlocked firmware.

You will populate the BL/AP/CP/CSC (NOT the home_csc) and the USERDATA (if it's there) in Odin and flash away
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dasdeschet:
So I prefilled all the sections from that firmware and now in the software section it shows XAA/XAA,XAA/XAA.

Does that look right?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
It's looking more and more that the N20 will be the last one...

Samsung fails to renew 'Galaxy Note' trademark in South Korea

The Galaxy Note trademark hasn't been renewed in South Korea, but the Galaxy S and Galaxy Z ones have.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
That's unfortunate
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dasdeschet:
I did as you stated and my CSC is now XAA/XAA,XAA/XAA. I would like to flash the carrier firmware so that I can have the ESIM capability. I did see the ESIM but what the carrier, TMobile, needed was an EID of which I could not find in the settings. Did I do something wrong? Or did I need an OTA from TMobile to enable it?

At any rate, should I have flashed it differently?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
When you flashed, was an active TMB SIM card installed?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dasdeschet:
No. But I do have one I can insert in there.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
That will be the issue. It has to be active too.

I would insert the SIM and flash that same set up again
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dasdeschet:

Can I ask someone here who has a U/ U1 device and who's on t-mobile using samsung messaging to send a group text to 2 people? Does the reply from that group come into your group message thread as it's supposed to on your device or does it go into the individual 's thread?

Mine is the latter and it has been happening since the August security update. I'm trying to troubleshoot if it's just my device (which seems likely at this point) so I can consider either factory resetting my phone or moving over to google message.

I can confirm that Dual SIM remains UNavailable on the U1 version with T-Mo firmware.

I have DUH3 on a TMB/TMB/XAA with Security Patch Level Sept 1, 2021, and no Dual SIM.

PS: Director's View, also no

Dual Recording: yes
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] 3GJockey:
I just gave it a try.

I have today's latest: DUH3 on a U1 and TMB/TMB/XAA with Security Patch Level Sept 1, 2021.

It's working, comes in as MMS. In the hamburger upper right, Group Conversation is turned on, and there's an option titled "Customize Chat Room", so it knows it's a group chat.

The Messages App I'm using is Samsung OEM "Messages" (the "contact us" link goes to Samsung) the version is 12.2.10.19

Is it possible you just have a bad setting? Say Group Messaging turned off, or auto download off?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] 3GJockey:
I could not dirty flash it to achieve this. It threw up errors and boot loops.

Kangi is right, if you want it to work, backup and do a clean.

Which is why I'm still on U1.

I want eSIM, but not bad enough to risk losing settings or stuff.

When my flash failed, I actually bought an Oppo A54 5G. So that's how I "dual SIM" for now.

BTW, it'll drive you guys nuts to hear how much I pay for an unlimited 5G phone line, international calling, and unlimited data from "Free Mobile" in France: 16 Euros, or about 20 bucks. And that includes 5 Gigs of roaming into other EU countries.

Thanks! I'm on a t-mobile U device so I have TMB/TMB/TMB with the latest August 1 DUH2 security update. I have my group conversation turned on and all my settings correct. I have reset all my apps, cleared cache from the samsung message app, wiped phone cache and rebooted tons of times.

Everything was working fine until the Damn DUH2 update that tmo pushed out a short time ago. Now all my group messages that people reply to go to their individual threads instead. The wierd thing is it shows as MMS in the person's thread so I can at least tell that it was supposed to go in the group message thread.

I have an unfounded suspicion as well that this could be an e-sim related issue which is what I'll look into next. I got rid off my physical t-mobile sim a while back so that physical sim slot currently sits empty.

What an interesting conundrum!

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
You can install either the Carrier version (U) or the Unlocked version (U1), but your SIM is going to dictate the features that are installed, that includes the bloat. The U1 version will see a little less bloat and you wont have the Verizon splash screen, but honestly there is very little difference between the 2. If you're looking for a ASOP experience (You referred to "Stock ROM"), you're not going to get one if your device is a Snapdragon

Well, FWIW, I also switched out to T-Mo eSIM back in May, when I thought I'd be getting the Dual SIM feature. But I don't have the SIM Manager setting, just a single eSIM and an empty tray.

Sounds like a nagging PITA. What you really need is somebody with EXACTLY the same setup as yours, not mine that's a little different. Good luck.

Thanks for your help so far with this. So yes, I would like to go to the carrier version to try and get the nice Esim feature.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Your problem is the ATT/ATT/CCT. To get OTA, you'll need to be ATT/ATT/ATT.

You'll need to flash the latest ATT firmware in post 2, use all of the files EXCEPT the HOME_CSC. Also, make sure your SIM is installed. This will wipe, and you may need to do the flash a couple times
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] derekdauzat:

Can you please post what you did in terms of flashing.

Here is what I did:

On ATPG verified ATT/ATT/ATT, with all ATT bloat and features.

1. Flashed U1 ATH3's BL AP CP CSC. No ATT boot logo, all ATT bloat and features gone. Verified ATT/ATT/ATT.

2. Flashed U1 ATH3's BL AP CP with U ATH3 CSC. Got back ATT boot logo, all ATT bloat gone, but ATT features back. Verified ATT/ATT/ATT.

I don't know why mine did not become XAA/XAA/ATT after step 1.

I read people with U1 device who did step 2 after putting ATT SIM in device were able to have ATT features with XAA/XAA/ATT.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ImmortalDemigod:
I'm just trying to piece as much information together as possible, still a little confused. I've been out of the game for awhile. I have a U1 model I'm using on AT&T. I want WIFI Calling and RCS back like I had on my Note 8 before I upgraded. Am I simply flashing U CP and Home_CSC from AT&T and rebooting to unlock those capabilities, does ATH4 (currently on ATH3) need to be flashed as well? And will I trip knox + lose my data from mixing firmware? I just don't want to go through the setup process all over again just to unlock those features.
