Any news on when TMB will release its Android 12 version? Eagerly waiting for it.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I wouldnt recommend it. There are enough times that I've seen a dirty flashes done on significant updates that create problems down the road

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dothanhthuy_haui:
I use note 20 ultra 5g t-mobile carrier has activated esim to use since android 11. If I update via odin android 12 using TMB version, can I keep esim to use?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ltmikepowell:
Yes esim still work. I just finished updating it. (Mình mới cập nhật lên bản Android 12 vẫn còn ESIM nha bạn)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] toastido:
For those interested, I tried a "dirty flash" from the U1 beta 3 to the TMB official by flashing BL/AP/CP/HOME_CSC/USERDATA in Odin, cleared cache, and still wound up in a bootloop. Glad I made that backup before I tried it :)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
A great example of my last post ;) Sometimes I really do appreciate SmartSwitch :D
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] borijess:
What is that setting in Android 11? The default DPI
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
You can get A12 OTA, no need for ODIN, TMB released today, check for updates. (As posted right above)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
Thanks. I don't feel like dealing with lost data right now. I'm doing the TMB update OTA. I guess I will have to wait to go back to unlocked until I have more patience. Smart Switch never seems to back up everything.

One thing I wish dual sim did that I believe IPhone does is to use data on secondary sim automatically when data from first carrier is unavailable/out of range/weak. I have Visible as primary and TMO internet only on eSim and the only way I know to use the TMO data is to change the primary sim. My other gripe is I can't get a visual voicemail app to work for Visible on the TMO rom.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] toastido:
Definitely. I just didn't wanna lose my data again (went from U to U1 for the betas), so I figured I'd "give it a go" as it were. Just posted my experience as a warning to anyone else wanting to try that.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Might be a problem with the apk Samsung used on that build. I fixed that by side loading the apk from apk mirror.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Selfesteem5:
Thank you so much for your help. I have another question, please, if you install the update, does it delete the data
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Put HOME_CSC in CSC slot that will avoid data wipe, ignore the other CSC file one.

Does the version below correspond to the N986USQU2DUC devices

Android 12s

Is it newer than the previous android 12?

Android 12
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] 3GJockey:
I've got a T-Mobile SIM in a U1 Note 20 Ultra.

After checking every day, I just got the Android 12 OTA today. Easy update, all of my data and settings remain, and I got dual SIM, which I have been waiting for over seven months.

Happy finally.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Sure has gotten quiet since the update to Android 12, folks must be pretty happy
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
Lol I have some gripes. But.. just things I'm gonna have to live with
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
I am! How you feel the official build? I've stayed on U version so far.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
Just got the T-Mobile Jan 1 Security update on my U device.

Quite happy with the A12 update so far. Although I use Nova Prime and I can't see much under the hood, I like the subtle changes that I'm seeing everywhere else. I like how you can set your battery charge to shut off at 85% which pretty much sadly will put these guys out of business. I also like how you can see your SOT since the last full charge which is something they brought back and should've never gone away to begin with. One thing I don't like as mentioned before is how they got rid of the alphabets in the contact menu and replaced them with dots instead. Boneheaded if you ask me but I'm starting to get used to it... Overall I agree that Samsung has done a great job with its One UI android implementation and improved it greatly to get it to this point.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Have links to the latest U versions for ATT/TMB/CCT/CHA and even got the latest VZW too posted in #2 for those who are interested
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
I just don't remember, but does the unlocked version phone app apart from the spam call protection built in, does it also have built in caller id?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
Yes sir it does.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:

I have gotten busy playing around Android Atomotive that's on my new car and spending some time on those forums. There is only so much time esp if you are a bad multi-tasker like me.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aloupha:
Had anyone with TM with a sprint plan gotten the OTA yet? I still haven't... Mine is the unlocked version.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
I'm sure all unlocked and Carriers got there December and January update.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aloupha:
I did get a security update, but not Android 12. Umm could it be because I have the beta?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Jobudden:
Yes sir it is because you're on the beta
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aloupha:
So, my only option is to Odin flash it?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Venom0642:
Most likely you need to go back to stable to get Android 12
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aloupha:
I got the beta via OTA though
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
That won't matter. You have to be on a stock firmware to get the stock OTA firmware.

The files for stock TMB/SPR Android 12 are in post 2.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aloupha:
I was thinking that since they offered a beta via OTA, they would offer the final version to the beta users when it became available. Many people don't have XDA or know anything about flashing...

I will Odin flash it then! I considered doing that but thought I would wait.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
Many people that don't have the knowledge or XDA would have to get their devices serviced. It could happen to any device with an OS on it. You just had back luck there if you didn't flash anything from here and the phone is stuck in that software. I've seen devices stuck in Android 10.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] nmnm4alll:
I have N896U which it's currently on the N896U1 A12 beta 3.

I'm thinking to go back to N896U.

Is it safe to just flash N986USQS2EULI?

TIA
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Absolutely
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aloupha:
Mine is an unlocked version, so I guess you meant post 3, correct?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
If you want to be on an unlocked firmware, yes.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aloupha:
I am merely saying that it seems unresponsible to allow people to be on the Beta and get stuck there. By officially allowing people to receive the Beta via OTA, I would expect to be able to receive the final version via OTA when it was made available.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
I can't speak to being officially in the Beta Program through Samsung Members, but installing any of the Beta firmware we were able to get our hands on and had posted here isn't actually "Official", those firmware would force anyone on it it have to manually flash back to stock
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
I do understand your point, however that's not how beta programs work. You always have that or any other risks by enrolling a beta, is actually at the service agreement before you jump in. Also if you are a regular user with no knowledge and no XDA you shouldn't use beta software in the first place. This could apply for any type of beta software.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Aloupha:
I have participated in many beta programs, and that's exactly how it works. When the beta ends, those in the beta get the final version via OTA. I do admit that I did not fully read the agreement beyond the instability of a beta firmware. At any rate, it's a moot point now, but it's good to know this is at least the way Samsung operates.

Alright, it's been a while since I have done this... which one of the files I should not flash if I don't want my data to be overwritten? Is it the HOME_CSC?

Edit: it would seem that I should flash the HOME_CSC, and not the normal CSC.

Edit 2: flash was successful! Thank you guys!

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] dj24:
Depends on how far you can stretch your finances.... You can just reorder the green one and then cancel the other one (Manage Your Orders from your first order's conf e-mail). The other option is to go the safe route and if you're going to slap a case on it anyways- find the best looking dark irish green case and call it a day ;)

Hey there, newbie here

I'm living in EU and got US unlocked phone on snapdragon. Do not have any US sim

So far everything works fine (wi-fi, LTE). I don't care much about samsung pay.

model number is SM-N986U1 and is XAA device, which is ATH3.

Is there a way to get it updated to ATI1 and keep everything unlocked? And if I do so, I assume, automatic updated will be disabled unless I re-flash so CSC matches.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Keep the U1 firmware and use the Home_CSC from TMOB that should solve your problem. Let me know if you have any questions.

Please try to read before asking. Few posts above I posted about flashing ATI1. You should try doing that. When downloading in Frija use USC to fill in CSC section.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jsminnis:
In the OP for flashing U1 firmware where it says "Flashed the U firmware" does it mean "U1" firmware with the "U" user data?

Edit: After more research, I decided I did not want to go the route of using userdata since it would wipe my phone.

The reason I came here in the first place is I've been seeing that some of the unlocked international note 20's are getting the beta and I was hoping the same would be true for the US version. After flashing U1 ATI5 I was still not able to sign up for the beta so I went back to the carrier version for now. Does anyone know if the US version will be getting the android 11 beta?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] jjr3211:
So I flashed my AT&T note 20 to a unlocked version. When I check in settings it says it is sm-n986u1 so I know that part when right no carrier apps or features but it says att/att/att. I thought it would be xaa/xaa/xaa
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
No Note 20s are getting to sign up for the beta (Not that i know of) as of now that is only open for S20 (Android 11 beta, One UI 3.0) .

Installed the ATI5 N986U1UEU1ATI5/N986U1OYM1ATI5/N986U1UEU1ATI5 on SM-N986U1 on T-Mobile.

Using the CSC = USC in Friya, used home_csc in Odin.

Works fine except several strange things after reboot:

1) Airplane mode was on for some reason?

2) Default apps were reset. Like keyboard switched back to samsung's one.

No major changes in the firmware that I've noticed so far.

Looks like on T-Mobile I'll have to use frija and odin every month now )

September patch is still not out, and others already got 2 updates!

---------- Post added at 10:33 AM ---------- Previous post was at 10:32 AM ----------

CSC changes depending on the sim card you've inserted.

Mine is unlocked by sams, but csc says TMB :)

And changes to att if I insert att sim card.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Queena:
I'm at my wit's end. I was sent a phone through insurance replacement that's unable to receive OTA updates. It's unlocked but is somehow an ATT version of the Note 20 Ultra. When flashing the latest ATT version of the Note firmware, Odin says that it's a write failed opertion. I'm not sure if I should try to flash another carrier, despite it being unlocked on the download screen it says that the carrier is ATT. I'm using a Tmobile sim card. I don't know if I should give up and get an S22 or what.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Are you using the Odin that's listed in post 2 or 3?

As far as the firmware is concerned there is no firmware specific to any of the carriers. They are technically the same, they install some specific things related to the carriers based on the SIM card thats installed.

If you look in your settings>About Phone>Software Information, what does it say under "Service Provider software version" and What is your Baseband version?
