It is really bizarre - but something triggered in my phone to switch it from an ATT Branded Device to become a Samsung Device on ATT -

Earlier (a few weeks ago) I verified that my phone was ATT/ATT/ATT in settings. Now, it has changed and shows XAA/XAA/ATT - and nothing I have done has been able to switch it back.

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

.

2. Flashed U1 ATH3's BL AP CP with U ATH3 CSC. Verified XAA/XAA/ATT - no Att Logo, No WiFi calling.

3) Flashed Full Stock ATH3 firmware - Verified XAA/XAA/ATT -no ATT logo, no Wifi Calling....

So, I have given up. I started a warranty claim asking for a replacement device on the Samsung web site - and shipped my phone (yesterday) back to Samsung. One of two things will happen:

1) Samsung will replace my device (I am returning it within the 14 day period of when it was purchased so it should be easy enough to get a replacement.

or

2) Samsung will fix the phone I sent them and get it to be recognized as ATT/ATT/ATT again.

I honestly don't care which option happens - just hope it happens quickly and I get my phone back soon.

Thanks to everyone for their help and a word of caution for anyone using a Stock ATT Device. Be careful when flashing the U1 CSC - I am proof that is possible that you can end up inadvertently switching your phone to become a non-ATT Stock device.

(will I still go thru the flashing to remove Samsung Bloat when I get my phone back ? - PROBABLY - :)

Thanks to all for their suggestions and attempts to help. It is really appreciated. Nice to have such a great group of people who can be counted on to try to help when issues happen. Thank you all very much.

Sorry you had issues with this. Out of all the times I have done this, it has never happened as you described. If I am going to try unlocked firmware on my U device I always factory reset before flashing. And then if I do go back to U firmware I factory reset again. What I have found when going back to U firmware from U1 even though flashing with Odin will wipe device, if I don't factory reset before flashing it never boots. And for those that choose to flash U1 unlocked firmware and want wifi calling back, you have to flash U1(BL) U1(AP) U1(CP) and U(CSC). Just remember that when you do this the software update toggle will be missing from settings and in order to get Ota the product code has to match csc.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Geekser:
I know what you mean - I never had a problem before either - not sure what happened this time. I have successfully done this on both my Note 20 Ultra and S20 Ultra, and never had the problem I described above. Oh Well, sh.. happens - and sometimes for no good reason other than just because. Glad I still have a good phone for backup use and looking forward to getting my note back from Samsung...

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] foxhound2001:
Hey guys, I have read up to page 13 here and ll I can say is that the I'm lost at most of the lingo you guys use... Been a while since I've used Odin which was the first and last time I did it for my S7 Edge so suffice to say that I have forgotten everything about it.

I recently purchased a N20 Ultra from a secondhand marketplace. The phone is a US AT&T version N986USQU1ATH3 which I am trying to switch to the unlocked version to use with my provider US T-Mo. Can I be pointed to the right firmware to download and is Odin v3.13 or v3.14 the one to use? Will switching to the unlocked version still provide OTA? Does this void warranty? Do I lose any function going for the unlocked vs T-mo firmware?

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:

hello, i want to make sure that my phone is using the proper BANDS - is this dependent on the firmware or the CSC?

I have a verizon MVNO branded n20u (spectrum) and sim is unlocked that I want to use on a tmobile mvno. I did a flash of the latest U1 FW also CSC (not HOME) and inserted my tmobile sim, the phone rebooted, but when I look at the software CSC still says CHA in settings and download mode.

I would love for the CSC to say TMB or even ?XAA?, but most important to know that the bands for tmobile are not deactivated - i know the verizon versions do not have band 12 active which tmobile uses for 5G in some areas.

FYI, I've tried doing the dialer code and using the band selector app and both methods are ineffective.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
You can flash any of the firmware (Topmost one is the most current). But if your current firmware is that old I would

highly

recommend backing up and letting the device wipe to start from a clean install.

Make sure to download the Odin from post 2 or 3, thats the one you need to use

If you flash the files I listed in my last post, that would get you a clean install

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Yeah sure sounds like it, that's really odd. Was it previously set up with your info? If so, I'd give it a factory reset in recovery mode.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ZTREETNIGHT:
Yep, previous a the flash I set up the account, and install a few apps, and when boot after flash, all still there,, you recommend me just make a factory reset in recovery or flash again with a option to make truly clean install?

I can OCD a bit, but if I were doing it, I would do a factory reset in recovery then flash the files I listed and see how that goes.

Steelplate..

If you are still on bootloader 1 on your note 20 ultra then the N986U1UEU1DUB5 is the last update that you can get without going over to the bootloader 2. I know bootloader 1 you can get root but not on bootloader 2. The "DUB5" update is Android 11 with One UI 3.1. That's what I got on my Note cause I don't wanna loose root access. But at the end I might end up upgrading to bootloader 2 versions just cause I've been thinking a lot about the esim option. I upgraded from Android 10 to Android 11 "DUB5" using the "Home_CSC" option and didn't lose any of my information. Hope that helps out with your question.

Note: bootloader 2 "DUI7" update for N986U1 does not have esim option enable as of this post.

Thanks Link. Very helpful

It seems our rooting days are numbered. eSIM sounds great, and it makes a lot of sense. But, I've had rooted phones since my Note 3 in 2013. I'm hanging onto my Note 4s to the bitter end when they pull the plug on them. Now I'm configuring (rooting) my n986u1 in preparation.

They have made some improvements to android to appease rooters such as sleeping, and deep sleeping apps... one time permissions, ability to delete apps that could not be deleted before. But, it's not nearly as good as root.

This site provides the evolution of n986u1 updates:

content://com.sec.android.app.sbrowser/readinglist/1018202502.mhtml

It appears that DUB5 is the in-between update with 3.1 yet 1 bootloader. I hate to assume that it's safe to update to DUB5 without maintaining the ability to ulock the bootloader. The BL unlock service recommends staying on 3.0. Do you now if going to DUB5 prevents (or relocks) the BL unlock? Should I update to DUB5 before or after BL unlock?

Apologies for the late response. I rooted my note when I was still on Android 10. I then updated my phone as per the steps that Kangi26 gave us. When I update from one UI 3.0 to 3.1 my root status did work but not 100% of the time. Some application couldn't get root access or crash. You can always downgrade back to 3.0 as long as you don't go over to bootloader 2. As you mention before, android has been updated with many features that gives us more control of the apps and can put them into deep sleep or you can always use adb to uninstall apps that you don't want. I hardly use root now but I like having it. ;)

"When I update from one UI 3.0 to 3.1 my root status did work but not 100% of the time. Some application couldn't get root access or crash."

Thanks for that. It ended my frustration of uncertainty about - to 3.1 or not to 3.1-

I will be happy with 3.0
