I had to use the patched Odin. My baseband version is N986USQU1ATGP

I'm on Tmobile, but it's unlocked. I think that it's the AT&T version that won't update OTA. I used the latest version of Android from here for AT&T hoping to gain back OTA updates. Well, I can't say gain back, because the phone is still on July 2020 patch. It's never been updated.

I was using the instructions provided on Sam mobile, and only flashing the AP file. I see these instructions on this website, I'm wondering if I wasn't doing a complete job.

If I follow these instructions, I won't brick my phone, will I? It's been years since I've rooted a phone or done any modifications, so I'm not sure if bricking only happens with rooting.

Update, I've done all of this and it still won't flash. It's stuck on the setup connection. I've tried multi builds, none work.

Last Edit

I figured it out. Someone told me to get the CSC and then find the firmware for the CSC a few days ago, and I didn't think that was important because it was unlocked. I had to do that, and once I matched that number, I found the correct build and was able to get it downloaded and working. Thank you for listening to my complaining.

Good, I'm glad you got it figured out

Hi guys, i have issue with software updates on my Note 20 Ultra, since i've bought it. It's still on android 10, one iu 2.5 and i have not released any updates yet. My phone model number is SM-N986U, CSC is ATT, baseband version is N986USQU1ATH3. SM-N986U1 model does not have firmware with bootloader 1 (which is mine) for the latest Android 12, only for Android 11 N986U1UEU1DUB5. Would you help me, please? Witch firmware should i download and install?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
It's your choice, you can flash either the

U firmware N986USQS2EULI or the

U1 firmware N986U1UEU2EVA9

These are both the latest versions for AT&T. Since your current firmware is SOOOO old (Aug 2020 kind of old), I would VERY STRONGLY recommend backing up your device and allowing it to wipe data

These both will update your device to Bootloader 2 firmware. It's not your device itself that has a "bootloader 1" or "bootloader 2", thats a part of the software package
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Deadclown:
Stupid question, but does this kill the root? and have to have it unlocked again?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Flashing a newer firmware will remove root. But if you have it SIM unlocked, that won't be touched since that's done from your carrier and is associated with the device IMEI
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Deadclown:
So I have to get it rooted all over again..... PITA seems my oneUI is at 4
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I was looking for the thread about how to root, but I cant seem to find it. One of the guys here was rooted, and I THINK he was forced to stay on a specific build because the root method wasn't with the current OTA builds

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
All of the carrier firmware for U1 are aligned to N986U1UEU2EVA9 , although I don't see anything that specifies xFi

Do you have an idea on why my ATT has the U version but the one marked as the TMO on post 1, and not matching the EULI version that says is the att one?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Sorry, I'm a bit slow today. So you're on ATT device running U - EULI? Sorry, I'm not understanding what you're asking

Sorry for my message. Here's my current build. However on post 2 it says that this is the TMO version, or it applies with any carrier version?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I don't know what the current ATT "Stock" firmware is (They can be really hard to determine because they don't release any of theirs), the last one I was sure about was the EULI build.

Was your last update OTA to this one or did you Odin to it?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
OTA
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
OTA was rolled out sometime on 3-21-2022 for AT&T AVC8 i did mention it a while ago on here.

Is there a link to ATT user data file anywhere for bit 2?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
The ATT files are really difficult to get, they don't release them. So typically I don't have access to them.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] yygemmi770:
I was able to get the unit to ATT without the file so all is good.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Link-82:
Hello kangi26.. I've been out for a while. In regards to root status on Note20 Ultra, that was me. Yes, if you are on bootloader 1 you can root your note 20 but if you upgrade to bootloader version 2 you will lose your root and won't be able to root it again until someone finds a different way of doing it. That's for snapdragon version.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Wow battery life is outstanding at 42% over 7hrs SOT , as you can see used some apps over and hour. Definitely this phone is a super beast.

If I flash U1 onto my ATT Note 20U, will I lose any carrier services? Wifi / HD Calling works now, without any extra steps? Or do I need to flash the CSC still?

TOTALLY frustrated with ATT's delay in pumping out updates.

Sorry for asking this, the search isn't working for me, for some reason.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
When I had my N20U I was on ATT and flashed the U1 firmware and I had Wi-fi calling. You will need to flash the BL/AP/CP/CSC (NOT the HOME_CSC) and it will wipe your device. As a side note all of the firmware is basically released on the same basic schedule(ish), so U1 will be as frustrating as the carrier
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Shanghai.Knight:
Thanks for this. Yeah, ATT Still hasn't released the download for OTA on this latest -- I'm sick and tired of ATT doing things different. I want a more stock experience, so I'm gonna wipe and flash. Thanks!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
If you've not run the U1 before, visually it's going to be EXACTLY the same as the carrier versions (Except the boot splash screen of course).
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Shanghai.Knight:
My understanding is that I'll remove the bloat, and get a different caller id, and a few other things. Also, I suspect ATT Smart WIFI is causing problems with my handoff on data connections to my cell signal.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Shanghai.Knight:
Oh, not to mention... I'll get the One UI version of Google Messages...

UPDATE:

Did what was suggested, didn't flash HOME.... ATT Wifi calling worked out of the box, no issues.

THANKS!

Hey there I'm currently using a Note 20 Ultra SM-N986U (ATT variant) with the baseband version being N986USQU2DUF2. The phone is unlocked as I am able to use my Malaysian Sim Card on the phone itself. I couldn't update the phone via OTA as ATT requires me to use an ATT Sim and connected to their network in the US, which is a problem to me because I'm living in Malaysia.

I wanna ask, can I just flash an updated firmware here? I'm afraid that it will brick my device leaving me with no way of restoring it, or on the other hand, I would lose my unlocked version that I currently have to being locked to ATT network. Are these real risks that I may face?

Eitherways, I am a noob in terms of flashing these newer phones especially phone that is carrier based. Which firmware should I actually download? I do not wish to install the U1 firmware unless I absolutely have to.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Yes you can just make sure you leave userdata empty and in CSC slot put Home_CSC that way it will just update your phone with no wipe.

Good to know my man. I'm having issues getting 5G+ on my Note 20, I tried everything regarding the network, (i work on an AT&T store and did the troubleshooting, sim card swap, network reset, without luck), only thing I haven't tried is to factory reset the phone. And also I haven't put my hands on another Note 20 U here to test. It was just to see if other users here were getting 5G+ on their note.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Only thing i get is 5G both phones never seen 5G+ On My AT&T Note20 Ultra 5G Snapdragon 512GB or even my S22 Ultra 5G Snapdragon

512GB

I live in Laramie Wyoming so not sure if that's something i would have to test more if going to Colorado Denver.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Yeah as far as I know, is not as widespread so it might also be that there's no 5G+ in your area yet. If you see something at any time let me know! I would appreciate it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Will do , when i go to Denver I'll keep and eye on it to see if it shows.

Just wanted to say Thank you! I had a very similar issue with the guy you replied to. I was stuck on an update from March 2021, and could not get OTA updates, and could no longer use 2g/3g mode to make calls. Followed you and OP's instructions, used the firmware you linked and I can finally use my phone again!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tooandrew:
I have a u1 that is a snapdragon variant that i got from Google store for use with Google fi. From what i have gathered it is a tmobile u1 variant. It looks like all the roms for u1 are exynos roms, and all the t mobile roms are non-u1 roms. Help? I just want to update but i lost my original fi firmware when i soft bricked my phone.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
U/U1 versions are US based and they are both snapdragon, U1 is the us unlocked and the U is the carrier locked. You can flash either or.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tooandrew:
The fw name translation in the op says snapdragon roms should be xxxxxxxSQxxxxxx while the ones listed on the u1 section are xxxxxxxUExxxxxx. Doesnt that mean the ones listed there are for exynos?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Not sure what UE means to be honest but knowing that Exynos is not existent in the US models and U1 and U are both US models you are safe to flash these (knowing that your device is either of those models).
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
No this is only Snapdragon thread so U1 and U are USA

Hi.

Would I be able to use this to downgrade my phone, ultimately enabling OEM bootloader unlock, and root?

I am currently on One UI 4.1 Android 12.

TIA
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Sorry for taking long to respond, but if you are concerned about this don't flash it. Or ask the people that unlocked the bootloader for you.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Depending on your bootloader version that probably is the 2, you can downgrade to any firmware with the same version not bootloader 1 if that makes sense.

So as far as im aware only bootloader v1 was unlockable, and then it was only unlockable by elliwigy from sampwnd (also a mod on xda) for a fee (claimed it cost him money to get the files for unlocking and he wasn't profiting, suspicious to me). I paid him to unlock my bootloader in jan 2021 and he was quick about it, but since then he has fallen off the face of the earth. Other xda mods say they haven't heard anything from him in ages, his website is still up and accepting payments but no one will reach out to you if you pay there and you will not get your unlock. You might be SOL on that root, homie.

Even when you could get it it was hella sketchy. You sent him uuid and something else from your phone then installed a vpn client and a usb over network driver and he odin flashed your phone over network usb through the vpn

Hello,

Sorry if this has been asked before,

I have Samsung Note 20Ultra 5G, unlocked and using it outside US

Model: SM-N986U

AT&T Carrier

Base version: N986USQU1BTIF

Android 10 / UI 2.5

01 Sep 2020 Security Patch.

I may never update the device but since yesterday I am having MIC issue with whatspp and other APPS skype etc voice calls, MIC is working fine on normal calls so its not hardware related issue

I have read post#1 and post#2 carefully.

So I need someone to point me which firmware is best to flash so I can get future auto updates ?

Not interested to keep AT&T APPS but more interested in device stability ?

I will take full backup before flashing to be on safe side and do not want to wipe the device unless its the last option so can I keep personal data after flashing ?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Your firmware is about 2 years old now............ REALLY OLD

The last AT&T factory firmware I have available on this thread is N986USQS2EULI That is from Jan this year, and should help a lot regarding features/security updates. Being as old as yours is I would NOT recommend a dirty flash. Back up and allow it to wipe.

If you want to avoid all of the ATT bloat you could flash the latest U1 I have here - N986U1UE2FVC5 I don't remember if this is an ATT firmware or not
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Shehary:
Updated note 20 with N986U1UE2FVC5 and after that it auto update to latest firmware, its service provider software versions says XAA/XAA/ATT/ATT so the firmware was AT&T.

But it didn't fix the issue with microphone, its still not working with whatsapp, skype etc but only works with normal call, I have tried almost every suggestion by searching about problem on google, nothing works, update doesn't work so any suggestion, can it be hardware issue, but how can it be if microphone working with normal calls.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] quantumtrap:
I just bought two Note 20 Ultra 5G phones on ebay from two different sources. They were both in great condition so I was lucky about that.

The first one I got was a N986U model and the other was a N986U1 model. I did all the software updates I could for both. The N986U model got three updates and ended up going from Android 12 to Android 13.

My issue: The N986U1 model only got one update which I guess was a security update because it stayed at Android 12.

Questions:

1) Is firnware OTAs being late a common problem with the N986U1 and other Samsung factory unlocked models?

2) Is an Android 13 firmware OTA just late for N986U1 or is it never coming?

3) Should I send the N986U1 model back and try to get a N986U model?

If your phone is unlocked its better to flash this U1 firmware, its unlocked no carrier branding firmware. After flashing the firmware go to About phone and check "service provider software version".
