Hi,
i found a Note 4 from at&t for a good price and want to buy it. What i am wondering is how will the phone work if i am using it with a Canadian carrier? I'm with Rogers in Canada. Will the phone still get OTA update from AT&T or will it follow Rogers' s update schedule?
Can there be any issues or loss of features?
You won't get any updates AT ALL.
Since its an ATT phone, it can only receive ATT software updates, but ONLY if you have an ATT sim card inserted. Since you'll have a Rogers sim inserted, the phone won't be connecting to the ATT network, thus won't get ATT updates. It won't get Rogers updates either since again, it's an ATT phone, not a Rogers phone.
The ONLY way for you to get updates would be through Odin, but ONLY if someone is able to upload the latest ATT update.
And no, you won't be able to flash a custom rom or the firmware from a different Note 4 version. And sim unlocking it won't fix the updates either, it'll only allow you to use the phone, as-is, on the Rogers (or any other) network.
All of this has been asked many times here, but involving different carriers. I'm griping about you not searching or anything, just letting you know that these past posts are where I'm getting my info from.

For those of you that have the Verizon S9/S9+ .. have you flashed the U1 unlocked firmware? Any bugs?
Do any of you still have the grandfathered unlimited data plan? Wondering if I can get the VZW S9, flash unlocked firmware, and have native hotspot work.
I have successfully flashed U1 and Tmobile Firmware on my g960 (verizon version)
So far, I have not noticed "bugs"
From my understanding U1 is what you get from Samsung Directly. With that said, you wouldnt have any incompatibilities as the barebone hardware is the same in the US variants.
One thing that I dont know though is software updates, if they are pulled OTA or if I have to flash every time.
Advanced Calling works as well as Wifi Calling and visual voicemail.
video calling doesnt work unless you flash a carrier firmware
If you have the grandfathered account with verizon, and you flash the U1 firmware. You can wirelessly hotspot or USB tether "natively"
Thank you for the information! Bummer about video calling, I use that more than visual voicemail.
Definitely sounds like this is the way to go.
Hi there,
I have a verizon phone and I am trying to use the hotspot with my unlimited old fashioned plan. I don't want to root. Unfortunately I brought the Verizon s9 not the Samsung S9 unlocked. Is there a way to bypass the company prompt for the feature and turn the hotspot on yet? I tried the one that works for sprint and it did not work for me with Shortcut Master Lite. Any advice would greatly be appreciated?

yeah you can flash your verizon s9 to the U1 firmware. this will remove that message, but not all things are guaranteed. also its not like youd be able to root your s9 as you got the US variant.
While I have a verizon hotspot plan, I tend to use USB tethering more than the Hotspot(wifi) option.
Checking on my dashboard online, shows that Im constantly within my Hotspot Plan.
I also noticed that on USB tethering, data doesn't count against my Wireless Hotspot plan.

Hi Eastsidebiz
Thank you for your reply. I apologize about not understanding all the lingo. When you say flash is that different than root? If you can flash and not loose your warranty or anything. My question is where do I go to have that done? Or is it something I can do myself? Also what will I loose as far as stock features if any? I appreciate any feedback and really truly thank you.

Flashing the firmware is different from rooting
Flashing the firmware is like installing a new OS on the computer.
Rooting is flashed preboot of the OS, and then executed when the OS is up.
Warranty / Knox by flashing an OEM firmware, this should not trip warranty/knox
rooting a US variant, if you can even do it, will trip your knox, thus tripping warranty.
If you have a US variant, come back to this thread 2 years from now, as i dont think developers are able to do so as of yet.
this thread is very informational if you need to flash your U version to U1.
Which s9 do you have again?
I thought I'd update this thread. I bought the VZW S9 and successfully flashed it to the U1 firmware to get rid of the verizon bloatware. Nice side effect is that the hotspot seems to work.

hey just a FYI.
If you flash another carrier firmware on that s9, you maybe stuck there.
personal experience: I can flash from Verizon to U1 and from U1 back to Verizon, (until verizon patches their firmware to lockdown)
on my other s9 (verizon, work phone) I flashed to U1 then flashed to Tmobile, now Im locked to tmobile, until another U1 and or Modded Odin
Thanks for that notice. As of right now I don't see any reason why I'd be inclined to flash anything other than the U1 firmware that I currently have.

Hi There,
So you are saying if I flash to U1 software I can use my hotspot. That is without being prompted by Verizon to add feature. What have you lost in the software from the U1 Flash compared to Verizon Software. If I do it and it voids the warranty so be it. I just want to see what I would lose before I do anything.

Newbie here, trying to read as much as possible but it seems my answers will be here.
What does it mean to be locked to T-mobile? Does that mean you can flash another stock firmware?
I just bought an Unlocked VZW S9 plus but I'd like to use Mobile Tethering and get rid of verizon firmware.
What firmware should I flash?

I bought the unlocked S9+ directly from Samsung website to use with Verizon. I got advance calling (VoLTE) to work but I don't see any option for WiFi calling/WiFi texting. How did you enable it?

What you are looking for is here:

Flashing this will rid of the bloatware from VZW and you can use the native mobile hotspot or PDANET
Locked to Tmobile can be a couple things, the Phone is actually locked to Tmobile's network (sim locked) ..then theres the Financial/Loss/Stolen/Fraud lock...
ALSO! have you updated your VZW S9's software from verizon in the last 3 months? If so, flashing a U1 may not work, I think the newest Update from VZW has v2 of the bootloader

What is your carrier?
I noticed that TMOBILE is the only one that allows all features to work when it comes to unbranded phones.
On my VZW s9, I flashed the U1 firmware. (using Tmobile) Then Wifi Calling was under the SAMSUNG DIALER option not in CONNECTIONS.
Then on my Unlocked S9, Wifi Calling was under the SAMSUNG DIALER settings (on tmobile), on Verizon SIM, this service is not available.
It looks like VZW/ATT both use their firmware to block outside access. Tmo on the other hand, allows you to fully use your Unbranded phone, but such terrible and outdated technology.
*for those who are getting 20Mbps on Tmobile and happy about that... why??!!?!?*

Unfortunately my phone seemed to have the latest firmware out of the box (February security update) so I might be out of luck then.
My carrier right now is Telcel Mexico (and we don't have fancy features like WiFi calling or VoLTE). I'm planning on switching to T-mobile soon.
What's that of the 20Mbps on Tmobile? Should I pick another carrier?

Wait Feb 2018 may still be V1 bootloader....
So what I noticed with Tmobile (im sure this doesnt apply to everyone) is after 1.2 to 2 years. Your phone line is no longer "new" and data speeds are dropped to least prioritization. Newer plans or line activation obviously gets higher prioritization. Mind you, im not a prepaid user. The only way to fully take advantage of TMOBILE is to switch your device or renew your plan every 2 years, which makes sense and average to some.
on the other hand, I have been having Verizon for the past 4 years, and used 3 different phones then (no line modifications, upgrade.. etc) and my prioritization has been constant. and averaging 70Mbps real time, about 7-9 MB/s (i download torrents on my phone) and its always constant (even if i go over 65GBs a month)... just my 2 cents...

Here's my take: I bought bought an S9 U1 direct from Samsung, did a Smart Switch backup of my damaged S7 to my pc, swapped the SIM and SD cards to the new phone, powered it up, did the Smart Switch restore and was good to go in under an hour, hot spot without prompt etc.
Based on this, if you can flash the U1 firmware you should get the results. The kicker to that is the bootloader version. My wife's s9 from Verizon took the August update and is now on build ... S3ARG9 - the 3 indicating v3 of the bootloader. The latest U! firmware available is S2ARF4 - bootloader v2 and you cannot downgrade the bootloader. BUT if you happen to be on the ARF4 or earlier build then go ahead and flash. Samsungs Voicemail app works with Verizon's VVM (basic), Messenge+ also worked, though I switched to Mood so that I can assign specific notification sounds to certain people.
Att to Verizon.
I bought a in Att s9 g960u phone and I want to use it on Verizon. I got a sim unlock code from a 3rd party so it is sim unlocked but I put in a Verizon sim and it doenlsnt connect to verizon. Is this because of the Att phone uses GSM and Verizon uses cdma? How do I get around this

Phone hardware should be the same. Possibly flash the U1 firmware. Or you may have to enter in carrier APN settings - I've never had to do anything like that but I have heard about it before.
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.
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

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.
I have searched for hours without any luck. I have been with an AT&T MVNO (Unreal mobile) for two years. During the 3g shutdown I was unable to use VOLTE on my S8 (VERIZON FIRMWARE). I found out the only way to use my S8 on UNREAL was to have AT&T firmware. I spent countless hours trying to flash ATT firware onto the Verizon S8, but I was unable to do it by flashing, but I found another way. I put a TMOBILE SIM in my S8 and it automatically loaded the TMOBILE firmware. Once the S8 was booted up I was able to run a USSD code (*#272*IMEI#) through the dialer which allowed me to switch to ATT firmware! Problem solved!!!! But a few months later my S8 was lost and I got a S9 (Verizon Firmware). I tried the same method as I used on the S8, but it doesn't work. When I put a T-mobile sim in the S9 it does not automatically change the firmware like the S8 did. From the Verizon dialer on both the S8 and the S9 it will NOT ALLOW USSD codes. Does anyone know if there is a way to run the USSD code (*#272*IMEI#) on the Verizon S9? Does anyone know why the Verizon S9 doesn't automatically change to T-Mobile after inserting a T-Mobile sim? Are there any other sims I can insert in the S9 to change the Verizon firmware in order to run USSD codes? Flashing my S9 is not an option for me because I must be too stupid. Anyhow thanks for your help!!!!
Seem's you+I have similar problem! I have s9 verizon unlocked,but I am with consumer cellular. They went to 4g recently now no call or recieve call! They gave me new sim, still not working! Told me shorter mobile wavelength from tower's! Last update on this phone was 2018? Won't update normal procedure! Wondering since this is U.S.A version if any way to update to 4 g? I'm fine on micro-soldering but when it come's to tech,a little to old I guess!!Lol Any help appreciated!

In my case I had a Verizon unlocked s9 and it turns out Verizon has bloatware that prevents many MVNO's from using VolTE. After tons of research the only solution I found was using patched ODIN to flash unbranded stock firmware in order to chance my model from a U model to a a U1 model. Now the phone works perfectly. Someone should file a lawsuit against Verizon (and ATT) for circumventing federal law on unlocked phones (technically they are unlocked but you can't use them because of their bloatware). It really is a major scam.
