Hey everyone, been awhile. Is it possible to flash AT&T rom onto the S20 Note? I just wifi calling since the quality is awesome and the deals are all for the unlocked version.

This is the s20 forum. I don't know about your Note, but the s20 can use the branded firmware for the unlocked phones if you flash it correctly.

I have a quick question for you guys, what is if there is any difference between the T-Mo and the AT&T variants of the Note II? I currently own an unlocked AT&T version of it, but soon I will also own the T-Mobile version of it. I know T-Mobile's does not have KitKat and is stuck back at Jellybean 4.3. After that, is all I can think of a difference. I currently do have T-Mobile. Will I be making a huge mistake by going to that variant?

If you're asking if it's a mistake to use the T-Mobile Note on the T-Mobile network just because the official firmware is JellyBean, no, don't worry about that. There are tons of KitKat and Lollipop ROMs in the T889 forum because of some extraordinary developers. You'll be upgraded in no time. Plus, with an actual T-Mobile Note, you'll have Wi-Fi calling, and it'll be better for overall network compatibility, anyway. Some users of unlocked phones on different networks report data drops or unreceived photo texts, for example.
Hope this helps!
Hi,
Im a first time android user and recently bought a Samsung Galaxy S9 (International Version - SM G9600 - DUOS - Snapdragon). I need wifi calling very badly on At&T as my work and home both have bad reception so my purchase has handicapped me from making calls. I see a lot of forums talking about flashing At&T firmware on G960U VERSION. But i havent seen a single one talking about flashing it on g9600. Is it possible? I compared the specs and every hardware looks same except dual sim option. Will I brick my phone if i attempt it? Please suggest im in need to help from the pro community.
Regards.

I dont have the dual sim but I do have the g9600 and also need an answer to this question also on a snapdragon
Hi all, new here and phone ignorant.
My parents wanted new phones this past Christmas and they like Samsungs. They had Galaxy S3's and so I bought them 2 new Galaxy S9's, model SM-G960U1. They worked great out of the box. I moved over their ATT Straight Talk sims and they have had no issues. They live out in the country and these phones get great reception.
Fast forward to last week I decided to order the same for myself. The phone that arrived was a Galaxy S9 model SM-G960U. I stuck in my ATT Straight Talk SIM and at first thought everything was OK. But, then realized the phone is missing Volte, wifi calling, and gets horrible data coverage and very weak voice service in the country.
Is there anything I can do to fix this, like flash the firmware? Am I stuck with it? Should I try returning it?
Thanks!
Flash it to U1 (unlocked) as your phone currently has "U" firmware (originally carrier locked). Read this thread to see how: https://forum.xda-developers.com/galaxy-s9/how-to/how-to-flash-u1-firmware-to-device-t3765200 . My S9 is an AT&T variant and I flashed it to The unlocked US variant and I use it on Simple Mobile. Wifi calling works, cellular data and cell signal - everything works perfectly.
Anybody have a S10 series on Verizon answer a couple questions for me?
I would like to confirm if or not bot Mobile Hotspot and MMS message work properly.
and any other quirks and besides the benefits of no belote ware, I'm planning on getting a S20+ but the Verizon version is $300 more than unlocked and I don't need or want Wi-Fi calling.
Thanks in advance
Curious if there is really an advantage to unlocked vs carrier in this case beyond ease of resale?

I've had both an Unlocked S10+ and a Verizon S10 (running Unlocked Firmware) on Verizon. Mobile Hotspot/MMS works on both, along with all other Advanced Features (including Wi-Fi calling/etc).
Thanks that's what I wanted to hear.

Had a similar problem on my S8 with att, flashed the att stock firmware through Odin and volte, and wifi calling worked. I have since changed over to the stock unlocked firmware to send in my phone for trade in and it doesn't work anymore. I order the unlocked 20+ as well do I'm hoping just flashing whatever carrier branded firmware for it works again.
Will the unlocked S20 Ultra work with Tmobile Wifi calling?
Hi,
Not sure but here's my history:
Bought an unlocked S9Plus from Samsung, had issues with WiFi calling on tmobile, never got it working.
So when S10 Plus came out I bought the Tmobile version from Samsung, everything works great.
So I just ordered the s20Plus from Samsung but the Tmobile version to make sure all is well with WiFi
and Tmobile's 5G systems. After a month or so I call Tmobile and get it unlocked, so no problem there.
Just safer to get all the Tmobile crap on there to be safe, also no issues with voicemail to text app either.

WIFI calling may not work I've been told. I just ordered a S20 + unlocked that I plan to use on Verizon. I would have gotten the carrier specific except I am buying it out right and would only get $300 trade in on my S10+ unless I used Verizon financing.
I refuse to do that so I went with the unlocked and got my $600 trade in. If I have bad problems I can always send it back and get the branded one.
My concern wasn't WIFI calling or VoLTE I had to make sure Mobile hotspot and MMS will work and I have been told they will.
I don't use the other features, so they don't matter to me.
So I have the unlocked S10 I use on TMobile work's beautiful and the s20 should as well I can even use wifi calling like you questioned which I hope carries over as well but I'm assuming it should I'll know in about 4-5 days
yeah every unlocked phone I have used on Tmobile wifi Volte has always worked, that`s why I stick with Tmobile, ATT sucked for unlocked phones....... except for the pixels, anything else wifi calling and VOLTE would`nt work.
As soon as I put my t-mobile sim in my U1 it re-starts and installs wifi calling feature. Just confirming it does work

Working fine on my S20+
Wi-Fi calling usually works on the unlocked Samsung phones, it's the in-dialer video calling that doesn't. Also, T-Mobile's implementation of RCS in the messages app doesn't work with the unlocked phones. It's usually very easy to flash the T-Mobile firmware using Odin on the unlocked model. That way you get all the carrier specific features. Make sure to boot your phone on the unlocked firmware (with the TMO SIM inserted) before you flash over to the carrier specific firmware. It's known to cause issues if you don't.

Do you know if the same thing works for Verizon? In other words, can an unlocked Galaxy S20 be flashed with Verizon firmware in order to enjoy any Verizon specific features, but still enjoy being bootloader unlocked and rooted?

You can't be bootloader unlocked and rooted since Samsung does not allow you to unlock the bootloader in the US for any carrier. If you're referring to Exynos phones, you can't flash those with the US (unlocked or carrier) firmware. For US phones, you can only flash the US unlocked to any of the US carrier firmware or the carrier phones to the US unlocked firmware.
You can find the firmware here: https://forum.xda-developers.com/ga...g986u-g986u1-firmware-links-flashing-t4054629

I heard about this was thinking if I could flash T-Mobile on the unlocked version will it remain unlocked? Or should I just use Google messages RCS

It's a very easy process and it will not "lock" your phone. You can flash back and forth with no issues.
T-Mobile RCS shows users who are on with a blue dot next to the contact name. It is also different than the Google RCS. If you want to use Google RCS, then everyone you message also needs to use Google Messages in order to take advantage of it. It's up to you if you choose to do it, but if you use T-Mobile and your friends and family do too, it might be worth it.
EDIT: Also if your phone is carrier SIM locked, flashing an unlocked firmware will not unlock it for use on other carriers.
