[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] nuprotocol:
Hopefully this post can breakup the silence. I currently have a Verizon Note 20 Ultra 5G.

SM-N986U

One UI 3.1

Android 11

N986USQS2DUE2

June 1, 2021 Android Security patch level

IMS Status = OFF (my main issue)

I recently ported from Verizon to AT&T and of course Wifi Calling and VoLTE/HD Voice do not work. When I make a call, data goes into 3G. I believe this is due to me using the Verizon firmware with the new ATT sim card. I believe I need to flash the ATT firmware but I do not know which one to flash.

My main goal is to get Wifi calling or at least HDvoice/VoLTE working.

I see the following firmwares:

N986USQS2DUE1 ATT/VZW/TMB/SPR. Thanks for the mirror @Venom0642 Mirror

N986USQU2DUDC ATT/USC/CCT

N986USQS2DUBB AT&T/USC MIRROR thanks @Venom0642

I downloaded the first one from that list but how do I know this is the one I need to flash in order to get ATT HD voice and Wifi Calling working?

Thanks in advance!

There's just really not a thing happening right now, in between OTA's and unfortunately not a peep on 12 for the N20U. I saw something for the S21 but nothing for us
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
If you're sporting an active ATT SIM, you would want to back up your device, and flash the DUE1 firmware. Make sure you flash BL, AP, CP, CSC (NOT the home_csc). I might even do a factory reset before flashing
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] znel52:
Haven't heard anything. We will most likely be waiting til November or December before we get a beta.

Samsung is supposedly unveiling the Z Flip 3 on the 28th. I am a little curious to see if it will have 'One UI 3.5'. If so we may see that in the next few months for our devices. Not expecting any major changes of course but maybe there will be a little something worth while.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] nuprotocol:
Really appreciate the quick response. I did a factory reset yesterday and will try to flash today. Thanks!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
You are right. This just showed up on my feed:

Exclusive: Galaxy S21 Android 12 One UI 4.0 update hints at early launch

Google may have launched the Android 12 beta but it's going to take some time before Samsung Galaxy users can ...

www.sammobile.com
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] nuprotocol:
I was able to successfully flash N986USQS2DUE1 onto my Verizon Note 20 Ultra. Initially ODIN failed the flash and I had a feeling it was due to me using the front USB port on my gaming desktop.

I then switched to the USB port directly connected to the motherboard and it worked. Once the phone restarted, I was greeted with a message that Android failed to load and my data could be corrupted. I restarted and the same message displayed.

i was giving an option to do a factory reset to resolve the issue. After performing the factory reset the Verizon logo appeared again and I thought the flash wasn't successful.

Thankfully I had my activated AT&T Sim card in the phone the entire time. During boot while displaying the Verizon logo I was greeted with a message that the sim card has changed and the phone needed to restart in order to load the correct carrier data.

The phone restarted and BOOM I was greeted with the ATT logo and processed the setup of my phone now using the ATT firmware.

Once completed, I can confirm the following now work on ATT, where as before with the Verizon firmware did not work:

Wifi Calling

HD Voice

Voice over LTE

5G service

Thanks to everyone that contributed to this thread. I no longer need to purchase a ATT phone and can use all of ATT's features on my originally Verizon Note 20 Ultra.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] znel52:
Funny how all the leaks start coming out as soon as you mention it.

Samsung's Good Lock changelog name-drops One UI 3.1.1, seemingly confirming the update

One UI 4.0 could be closer than we think

www.androidpolice.com

This article is saying beta could start next month for some devices with stable release in line with Google. I'm not really believing that but you never know. Google and Sammy have been getting close and working together a lot lately.

EDIT- Not really clear in the article if they mean internal testing next month or some sort of open beta program. If they just started working on 12 seems like it would be internal only but who knows it isn't very specific.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
True that surprised me too.. That all the leaks started.. Well it gives us something to look fwd to. If they start early then better :)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] delsoul6:
Just switched from VZ to ATT and having the same issues as nuprotocol with limited functionality due to VZ firmware still being on phone. I've been researching for a couple of days what to do and it led me here.

Nuprotocol flashed the N986USQS2DUE1 firmware and ended up getting it working but said he had issues at first. In an effort to make sure I do everything right, does anyone know why the issues he stated happened? I did a hard reset 2 days ago. Do I just need to flash those files in Odin and that's it? At first I thought I had to flash from U to U1 and then back to U to get ATT firmware but I'm not sure I understood everything correctly. I have N986USQS2DUE2 just like nuprotocol. Can anyone please elaborate to ensure I don't make any mistakes? Also, when people say to backup first, what software is recommended? Do you just mean through Google or something like TWRP or Titanium. I used those years ago but not sure if they are still in use with the N20 Ultra.

Nuprotocol - any tips or suggestions since we are in the same boat in case maybe to realized later you did something wrong?

Thanks!
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
1st off, unfortunately TWRP and Titanium are available to use without root.

You can use SmartSwitch (Made by Samsung) to back up to extSD. Additionally I make sure that I manually have my device folders saved to my extSD too (I'm a bit paranoid it might miss something). But if you did a reset a few days ago there may not be anything on the device to save (Your choice if you need to or not)

You don't have to flash to U1 and back, that's not necessary. DUE1 is the current stock one for ATT, so to get OTA updates in the future that is the one you should flash.. When you're ready, make sure your ATT SIM is installed, do a factory reset then in the Odin posted in the OP, flash the BL, AP, CP, CSC (NOT the HOME_CSC). The device will go through the set up and during the set up will install the ATT bells and whistles
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
A thing to keep in mind is that all of the firmware posted here will work on any N986U/U1 devices regardless of the carrier. I only post the carrier name next to the firmware so we can ID which are the current stock so folks can get OTA.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] delsoul6:
Thanks for the quick responses, kangi26. The process seems simple enough. I think I last used Odin on a Galaxy S4 so it's been a while. I don't have anything to back up except photos and text messages so I should be okay. I wasn't sure if there was a system backup I should be doing to avoid bricking. So I should factory reset again and then when it's on the first screen after resetting, turn the phone off and begin the Odin process?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
The way I do it is to go into Recovery mode, do the factory reset, then when it's complete, power off. Then Odin the new firmware.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
Oh and getting into Download mode is WAY different than the older devices you're accustomed to.

Be sure to open Odin and load the files for flashing then

From the OP:

How to enter Download Mode:

Turn off the device.

Connect USB cable to your PC (Leave it disconnected from the phone)

Press and hold down the Volume Up and Volume Down buttons. While they are still pressed, plug in the USB cable into your phone.

The phone will go into download mode press volume up. In Odin you will see that phone is added.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] delsoul6:
Thanks so much, kangi26. This is the most expensive phone I've ever had so it makes me a little more nervous that I missed something and might brick it. I'm going to try to get to this tonight. I will report my results in case it helps anyone else.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
No problem at all! BTW it is REALLY hard to brick now-a-days (Ok, so if you unplug your USB when flashing you could brick). Things are a lot different than they were years back.

I think you'll be fine.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] delsoul6:
I flashed the phone last night and everything was successful. I had the exact same results as nuprotocol where there was first an error and required a factory reset, then it rebooted with VZ for a while before saying new SIM found, then rebooted with ATT software.

Everything works perfect but I did notice in software information, under service provider software version, it says ATT/ATT/VZW. Not sure what that means but something from Verizon is still on there.

Can someone help me bootloader unlock and root my AT&T G8 on 9.0 Pie, April 1 2019?

$15 in btc to anyone willing to help over teamviewer or other remote control software, the guides available are poorly structured and I'm kind of unsure how to proceed myself. I downloaded all the required files, and will happily pay to have someone root it for me. I am on the April 1st 2019 patch, G820UM10i.

[Xiaomi Mi A3 Questions & Answers] dwombat:
Hi all. I feel like a bit of an idiot. I've been rooting phones for a while, and I finally decided to swap to something new...but I slipped up...and messed up...and feel like an idiot...

I can still get into slot a without a problem (boots into regular os). Slot b though doesn't have an OS. I can't boot manually into TWRP either:

$ fastboot boot twrp-3.4.0-0-laurel_sprout.img
Sending 'boot.img' (39892 KB) OKAY [ 1.115s]
Booting FAILED (remote: 'unknown command')
fastboot: error: Command failed

Reflashing twrp to boot_b doesn't work...any thoughts? Worst case, I have the stock OS I guess...

I was able to get it back into TWRP with some trial and error. Weirdest thing is that SHRP was installed with crdroid? Weird...?
[Xiaomi Mi A3 Questions & Answers] Golbinex:
1. You cannot use boot command in fastboot,

2. This device doesn't have recovery partition, recovery is contained in boot partition which will be always overwritten by custom ROM, thus you got SHRP which I recommend to use, because TWRP is outdated. However if you want to use other recovery, you must always flash it's installer zip right after flashing custom ROM.

I just saw that Amazon is now selling the buds with Monday delivery. My order status with Sammy is still showing delivery August 21. Shucks.
[Samsung Galaxy Note 20 Ultra Accessories] pouelle:
If it's Amazon, I wouldn't hold my breath. The last several delivered by if ordered by dates on my orders have been missed, one by a week. Last order I made was supposed to arrive on the Amazon delivery day of Saturday (ordered Tuesday) - got an email today saying it would arrive Sunday (not holding my breath)
[Samsung Galaxy Note 20 Ultra Accessories] advocate2:
What's interesting is that Sammy is showing my buds as to be delivered August 21 but has already shipped my Case. Amazon is showing the case as Usually ships within 1 to 2 months.. Go figure.
[Samsung Galaxy Note 20 Ultra Accessories] marctronixx:
yeah i ordered the usual samsung military style case from samsung like i always do and it shipped today, with the buds, watch, and phone shipping on the 19th...

The first Customer reviews are in on Amazon and they are not kind.

https://www.amazon.com/product-revi...20F6593&showViewpoints=1&ref_=lv_ov_lig_pr_rc
[Samsung Galaxy Note 20 Ultra Accessories] cpufrost:
I trust Amazon reviews these days as far as I could throw them, not sure how maybe print them 8x11 and make a paper airplane? If that's the case then, yes definitely NOT LOL! :D

Because of the shape and lack of anything actually going in the ear canal (as well as a loop) methinks this is going to be a very personal thing here as ears come in all different shapes and sizes. Some of us will have them practically fall out where others they will fit like a cork in a champagne bottle!

And of course sound is subjective.

The one review mentioning poor range and static/noise is using an S8. These probably work best with a bluetooth 5.0 device. Just like an old laptop with 802.11b isn't going to get very good speed on a Wifi6 network. Probably a bad analogy but that's how tech works. ;)

I got a "free" pair with the $200 store credit, don't really want them but not going to piss away "free" money, they got to be worth $100 (net) on fleabay, right?
[Samsung Galaxy Note 20 Ultra Accessories] advocate2:
I wonder if the first couple of Amazon reviews were Trolls? The reviews improved substantially. Kinda ticked that Amazon buyers have them already and Samsung direct buyers are waiting.
[Samsung Galaxy Note 20 Ultra Accessories] marctronixx:
not gonna trust amazon reviews, positive or negative, in this matter because people's ears and listening preferences vary waaay to much.
[Samsung Galaxy Note 20 Ultra Accessories] Apex i ITR:
yeah it seems like a bunch of the reviews after the few negative ones are all positive.
[Samsung Galaxy Note 20 Ultra Accessories] bkeaver:
Seems to be more good pouring in than not actually. Of course I take all reviews posted there with a grain of salt as everyone has their own expectations and opinions.
[Samsung Galaxy Note 20 Ultra Accessories] Talderon:
I ordered off samsung.com rather than Amazon. I was able to get a Military Discount as well as use my Samsung Rewards Points for even more of a discount. So, all in all, paying less than $100 for these was nice. :D
[Samsung Galaxy Note 20 Ultra Accessories] Dewda:
I am using a pair now and enjoying them. They are responsive,bstay in the ear pretty good, and it's actually not easy to make them fall out. The sound is not tinny like some earbuds and they pick up background details in songs that some earphones miss. So far they are more comfortable and more dynamic than my Galaxy Buds and a host of other in-ear types I've tried.
[Samsung Galaxy Note 20 Ultra Accessories] marctronixx:
i agree with your post. I was listening to a song i recorded off vinyl and until now I was not able to hear the subtle cracks and pops of surface dust on the record on my old buds i got from the note 10 pre order last year like i do now on these. the sound quality is really an improvement and the fitment in my ear is fine. i didnt mind the "stuck in your ear feel" of the buds from last year, and i dont mind these either. they do give more of an ope air feeling which some may find pleasing.
[Samsung Galaxy Note 20 Ultra Accessories] Dewda:
[MENTION=543144]marctronixx[/MENTION], that crack and pop sound and random noise makes the music more real IMO.
[Samsung Galaxy Note 20 Ultra Accessories] marctronixx:
agree
[Samsung Galaxy Note 20 Ultra Accessories] Ricey:
Can't decide between the white or black one. My note 20 is white, but those 2 colors both look nice. I feel I'd only get bronze if my note20 was bronze.
[Samsung Galaxy Note 20 Ultra Accessories] advocate2:
I received mine with the pre-order bonus and have to say that I am really impressed. I like the feel in my ear and they seem to be secure. They won't match noise cancellation with my Bose on flights, but aside from that they are a joy.

Are your proxy settings on..... Try this

If your proxy settings are on, they are blocking the port for Skyfire to connect to the internet.

Here are instructions on how to turn off the proxy:

Go to Settings, then to the Connections tab

Connections > Advanced > Select Networks

Under "Programs that automatically connect to the Internet, should connect using"

Select

MediaNet for AT&T users

T-Mobile Data for T-Mobile users

Sprint – MyISP – PowerVision

Verizon – MyISP – Broadband Access

In Proxy Settings, make sure to UNCHECK: "This network connects to the internet" and "This network uses a proxy server to connect to the internet" If you are a Sprint or Verizon customer who is using “My Work Network,” make sure to UNCHECK usage of the Proxy server. If you are an AT&T customer, you may want to refer to AT&T support to configure your connection settings so they bypass the AT&T proxy.

T-Mobile customers, please note that several people using T-Mobile’s limited t-zones data plans have reported issues connecting to the network, this issue exists for both Symbian and WinMo users. Based on the forums, the limited t-zones plans only allow WAP web access, and only allow connections through port 80. Since Skyfire renders full websites and uses additional ports, you cannot connect using this limited plan. (This T-Mobile plan is sometimes referred to as the “$5.99 plan”.) You may use your wifi connection to connect Skyfire to the internet or the unlimited T-Mobile Total Internet plan.
