You would flash USERDATA_TMB_N986USQU1ATH3
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
If you flash the ATH3, with the BL, AP, CP, CSC and USERDATA as long as your device has an active TMB SIM, it'll flash the TMB features automatically

Edit... Keep in mind this will wipe

You responded to late[emoji1787]
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Oh for petes sake

FAIL
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] butchieboy:
Omg...i crack myself up. Thinking about going back to ATH3..havent setup yet and have every file known to man. Just want to stay on track.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Someone has WAY to much time on their hands :laugh:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] foxhound2001:
Is this one of the download linkl on your second post N986USQU1ATH3 LINK ATT/CCT Aug Security? Will this still be able to do OTA?

I tried using Frija but I didn't know what to type under CSC. and if the rest of the settings is best left under automatic
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
The ATH3 will work, it's stock for ATT and CCT and will only get you OTA if either of them are your carrier.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] butchieboy:
Hey...its a holiday..belly is full just sitting around. And as usual At&t sucks. Went back to ATGM to see if it would Ota and says current firmware is up to date
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
AT&T isn't ATGM for older firmware the July Firmware for AT&T Note20 Ultra was ATGP
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] butchieboy:
Lol...i just realized that[emoji1787][emoji23]looked at box..yepATGP

I know better...don't know what the hell is wrong with me today
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] foxhound2001:
I just finished flashing the phone using firmware N986USQU1ATH3 and for some reason it kept all the AT&T garbage on the phone along with the splash screen... What the heck am I doing wrong? I just want to swtich the firmware to the unlock / no carrier version of this phone.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] testrak:
You flashed the U FW which is carrier branded. You need to flash the U1 FW N986U1UE1ATH3 to get rid of ATT bootup splash screen and bloat.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] foxhound2001:
Thanks for the clarification. Would you happen to know where to get the userdata for N986U1UE1ATH3 or do I not need one? Am I correct to assume that this firmware will provide OTA?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] testrak:
No need for Userdata.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] gold3ndrag0n:
You need to follow the directions at the bottom of the first post of this thread. CSC for U1 is XAA and T-Mobile is TMB in Frija.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] burrzoo:
I have an issue that personally, I've never seen before.

When I first got this unlocked N20U, I only installed the CSC file the put my AT&T SIM in & everything working great.

Today I'm reading that there is a September patch rolling out.

I go into my Settings & the Software Update section is missing! How can I check for an update?

Can anyone help?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ram4ufriends:
If you change CSC, you won't get future updates...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
The very 1st one in post #2,

N986USQU2DUJ6 ATT/TMB/SPR/USC/CHA/CCT.

Be sure to flash the CSC not HOME_CSC, it will automatically wipe the device
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] MrRubik20:
Thank you so much!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] MrRubik20:
Guys I have checked to see if the Beta was available for the Note 20 Ultra for about 2 months now. Now that it is, I don't know what it's all about. I got it to install. The UI looks the same. I got a remote control quick button. But I couldn't sign into my Samsung account. I couldn't sign in with my Google account. I kept getting all kinds of errors. Nothing looked anything different at all. It just looked like ONE UI 3 with a 12 instead of an 11. Am I missing something? I thought this was supposed to be a huge update wit UI changes and all kinda of different stuff. Was I imagining? I have no problem going to U1 if I can get it t work and it actually be cool but if there is not enought difference there is no noint. Anyway mind posting some screens of what their UI 4 looks like ? I wanted UI 4 so bad.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I'm not totally sure what happened with your install, aside from GPay, I've had ZERO problems.

That being said, all of the screen shots that I'd seen were from the Pixel, but Samsung has a very different vision of what OneUI would look like. I don't use it, I use Nova or Microsoft launcher so I can't provide you with any thoughts there. There are some small changes to the nav bar, transitions, battery charging symbol, and some other things. But yeah it does look pretty similar from my perspective.

If you want screen shots do a quick Google search for the S21 beta I remember seeing some of there
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Not sure was happening to your flash , but Android 11 and Android 12 they both are almost identical, few new things in Android 12 but not much will be noticed.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Also i was on the beta Android 12 for 30 minutes, i went back to Android 11 lol , cause not much on Android 12 as far as i saw, so i flashed back to Android 11.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I am seeing a couple new features available in the Quick Panel,

Microphone Access

Camera Access

Extra Dim

There is also a "Color Palette" in the Wallpaper and style menu in Settings too, havent played with it at all

Device Care has had a little overhaul too. Although my device is still learning patterns, I can't tell if there's any improvement in battery
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
For those wanting to know what changes have come to Samsung with Android 12, here's a SILLY screen shot
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bassman418:
Have a question. I flashed U1 over my U (Verizon variant) and then updated to the beta. Everything seems to be working smoothly, but I have a Nova Launcher icon I can't get rid of on my home screen. I can move it around and even throw it to the side and it minimizes to a little handle with a figure of a person. Anyone else have this or

figure it out? See attached
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Hmm looks like accessibility check there.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Think is the gesture check picture.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bassman418:
Thank you, that was it!!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bassman418:
Will I now be on the Beta update track, or have to manually install them? (And if yes, will we be able to download them like this update)

I went to the members page and it welcomed me to the beta program, but when I click anything on that page it tells me I either didn't register or change my country or something
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I had the same thing on mine as well when I re-loaded 12. I honestly can't say if you'll get the OTA or not.

The joys of Beta :D
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Michael in ATL:
Same thing was happening to me after upgrading a couple of hours ago, but the error has gone away now. It now says "Thank you for participating".

Update: I'm still getting the haven't joined message. I took the above notice as a head-fake.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
Just got the Nov security update for t-mobile..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Which firmware? U/U1 or Beta?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
I'm on U.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bassman418:
I had gotten the Nov security on Verizon a few days ago on U too. for some reason Verizon pushed 2 updates in october and neither was Nov patch.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bassman418:
hopefully when a new beta gets released, someone will be able to post it for download. Everything seems to be working good, but im having issues with (of all apps) XDA app. i can sign in, but then the next time i click on it to open, it crashes. i have to clear all cache and data ,relaunch and sign in everytime.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
I would uninstall latest XDA and go back one version this one

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bassman418:
I noticed something with charging today. I have a Samsung Fast wireless charger and the 45 watt Super fast Samsung charger I use at home, and the phone charged perfectly all weekend. Today I got to work and threw it on my regular fast charging cord and brick the phone came with (kind of rounded brick with USB C to USB C cord) and it did work at all. So I put it on my old cord and charger (square Samsung fast charging brick with USB to USB C for lets say a Note 9) and it works perfectly fine. Funny thing is my fast wireless charger at home uses the same cord and brick that isn't working when plugged into.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bassman418:
Thank you. That let me log in and stay logged in. But is locking up and acting strange..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Reason i told you to roll back cause lot's are having issues with latest XDA app even on Android 11 it will crash won't let you back in was also happening to me on My AT&T Note20 Ultra 5G 512GB Snapdragon with Android 11.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I only used the app for a very short time because of that. I pretty much stick to launching it in Chrome
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Decided to wait to see if we get the banner on Members app with no luck, have anyone seen the banner again after about a week? I believe we don't see it because the program is full, so hopefully they will open more spots so more people can go in.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I went back to U1 and haven't seen it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
I still see the banner. See my screenshot taken around 6 pm EST today (22nd Nov 2021)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Dang I'm jealous :(
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I played enough in the Beta and I'll just wait till it's full stock OTA, need my device to be 100% operational right now :(
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Is it that bad?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
I am in the right software to be eligible for the beta program right?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Yeppers you sure are
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
No not at ALL. It ran really well for me (Except the GPay issue).

I can't risk any potential bugs right now and it'll likely require another wipe to get back to stock (If I remember from the last time I ran a Beta)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
Currently on the beta. It's not that bad. I use Samsung pay over gpay. One thing I'm not really liking is. The letters in contacts being gone lol. Its just dots for me. Other than that I don't have any issues with it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
My personal annoyance was the icon names were gone on the App Panel
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
I want to give it a try but I don't want to go through the whole wipe process :(. Does the adb method wipes too?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
It's not that bad. I back up with smart switch to my SD card. Puts pretty much everything back. Just have to re login to everything lol
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Yeah it will
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
I had a different experience here. I was going from U1 and correct firmware to beta and my device was originally U1. When flashed using adb I didn't lose data. Now we are looking at someone to confirm, the more scenarios we observe the more we will be able to tell when it wipes and when it doesn't.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
Hi I hope you get the 2nd beta update for note 20 ultra.. thanks
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
Is there a second one already?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Haven't seen one for our device yet
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Well bugger.....

I might flash it again.....
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
N986U1UE2ZUKA is the version I think
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Also now it has esim support.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
I hope you can get the new link..😁

Yes someone on reddit confirmed Sim card manager works
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
@dan96815 did you manually flash or got the banner the official way?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
Manual and it didn't wipe
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
And you got the OTA? I think I'm ready to manually flash too. Thanks my dude.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
Cuz Canadians don't count in Samsung world
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
No we need a zip to update to beta 2
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Oh that screenshot you submitted before is from someone else?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
Yes to show its real...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
I get the welcome to samsung beta but then I get server error try again later.

But I've been getting that for a long time with no fix lol
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
So manually flashing breaks OTA confirmed.. :(
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
You will only get betas if you have a US phone and on U1 firmware and in America too I think
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
No only elegable phones will get betas until official
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Does the new drop fix GPay?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Not even, the beta program is full, so even if eligible there's no way to get the banner to sign in, my concern is if manually flashing breaks the OTA and it looks like it. Even in the right region, device, etc.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
Gpay worked for me I always wipe after the zip flash
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Does it continue to work after a reboot?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
You can flash all the betas then when official just flash in Odin need to wipe though
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
There's a chance I'll flash the beta..... AGAIN maybe later this evening and see if I do get the OTA. I'll let ya know if I decide to and if it does OTA
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
I am think of flashing it again if I could get the 2nd beta but when I used it it worked
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
I guess you need the members app to get the bin file?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I have the bin file for the 1st beta
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
I can confirm Google Pay works fine for me after update to One Ui 4 beta. I updated through Samsung Softwate Update after registered for the Beta Program, No wiped needed.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
Saw this on another thread
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
Can you get the new one?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Going to try ;)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] SuperSHO:
ATT version on 1st beta. Just went into the Samsung Members app and it showed me in the beta; it never showed that before today.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dan96815:
I think gpay won't work because android is not certified
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] DevVorteX:
So, you sideloaded beta 1 and now you were able to officially join the beta program?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] SuperSHO:
That is correct. But before today, it didn't work.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
So I get this for months now. Contacted Samsung about it. Never received any help.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
XDA app fixed the loop crash with another update.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
@kangi26 still unable to add card on Google pay but it seems it should be working, I just updated so will have to check again.

Esim is here for unlocked ones now.

Please feel free to download Beta 2 from this OTA link and add the firmware to this thread.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Awesome, thanks!! Is this one still BL2?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Yes. Sorry for late response busy day today.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
No worries, thanks for responding. I had gone into the update and saw that it was BL 2 but couldnt remember where I asked this, so I could edit it ;)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] bassman418:
I have a question, I downloaded and it's a bin file at like 441mb. Is that correct, or did it not download properly. I thought it would be a zip file.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
You have to change it. Just rename the whole file to update.zip
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Link to Beta 2 file and updated instructions are in Post #2
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Michael in ATL:
Thanks to you and Kangi, first of all.

I have tried installing via my SD card, but the installation aborts saying "E:footer is wrong Error 21" (no quotes)

Error 21

I also tried via adb sideload but got error 2.

Any thoughts/suggestions appreciated.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Honestly, I don't have a clue what that error is.

Dang, I'm going to be forced to test this out myself....

;)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Testing the install to Beta 1, then to Beta 2 from my ext SD. I'll let you know what happens
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
At what point do you get the error? Are you already on Beta 1?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Michael in ATL:
Thank you guys for the responses. I'll post the full error later. I'm restoring in Beta 1 for now. I need to go the my in-laws as soon as this is done.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
So I have the beta 1 Update.zip and the beta 2 Update2.zip loaded on my extSD

Beta 1 installed with out any issue

At the device's 1st boot, I shut down and rebooted into Recovery

Installed the Update2.zip

The device wiped on each install and the Beta 2 installed just fine for me

I know that doesn't help you with your issue, but it does tell me that possibly there may be an issue with the file(s) you downloaded? And download them again. Sorry, but thats my best guess at this moment
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Hey i have a question for a friend since i never used unlocked firmware on a AT&T Carrier phone,Does Unlocked latest firmware Android 11, with service from AT&T did they add all the AT&T Features can't remember read a while back so i need you to refresh my mind thanks.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Stuff like the WiFi Calling? That one specifically is there, I'm trying to remember some of the others........ Thats the big one though
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
ok what i need to know wifi calling, Volte, Advanced Message, Video call etc etc the features AT&T Carrier has.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Wifi calling - Yes

Volte - Not sure

Advanced Messaging - I am using it with Google Messages

Video Calling - Looks like thats a yes too
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
One more thing does it make the software update in settings disappear, if i remember i thought i saw something being mention about it, and that you won't get AT&T software updates when changing from U to U1, is this correct?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I was getting the ones for AT&T, just so happened that all the builds align. So my device was ATT/ATT/ATT if that helps
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Wait ok , so are you telling me if i flash DUJ7, U1 firmware on my friends AT&T Note20 Ultra 5G Locked it will now show ATT/ATT/ATT

,Did that change .
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
That's what my phones shows. I just hopped onto 12 right now, but that's what I see on 11 too
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Interesting, so my friend won't have the AT&T Bloatware correct? that's why he wants to odin to N986U1UESDUJ7 , Sorry i asked all these questions i felt like a newbie 😅 🙃, It's only more of me just sticking with U .
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
There is A LITTLE bit of bloat, nothing compared to the U version
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Ok Thanks, I'm gonna have to do odin N986U1UES2DUJ7 for him he has no idea on how to do it, anyways To go from U to U1 in slot csc i assume that i put csc instead of home_csc?

One more question which i haven't seen you mention, does he lise OTA ?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Use the CDC, not HOME. It needs to wipe

He'll get the U1 OTA
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Thank you, i will let you know how it goes, i am gonna use odin3 patch one.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Michael in ATL:
This is a lousy shot of the error, and when things go sideways for my attempts to upgrade from Beta 1 to Beta 2. Results are the same whether I use the filename shown or use "Update.zip". Any thoughts? I sure would like to have eSIM back, as I have a work phone as well.

I reformatted my first SD card and copied the files over after verifying their MD5s. I used a 2nd SD card w/ the same verified update files, and same results again.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Sorry, I'm not at home right now but I've see the signature error before. Do a Google search on it, I want to say it's something to do with the file don't remember
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
The Reason your getting that error is you need to open the zip and pull out the zip that says update.zip , Then you flash it thru your sdcard.
