Reflash Unlocked Verizon Note 9 - Samsung Galaxy Note 9 Questions & Answers

Recently purchased an unlocked Verizon Note 9 on eBay. Works fine with my Verizon Sim however when booting I get the Verizon bloatware and updates come from Verizon. I want to reflash the phone to stock Samsung ala my Note 10+ which I bought directly from Samsung (no Verizon bloatware) and use with Verizon.
Questions:
If I reflash the latest USA (non carrier Specific) Samsung Note 9 firmware via Updato will future monthly security updates come from Samsung or will I have to manually install from Updato?
Regarding banking apps and GPay/Samsung Pay will they work after installing stock Samsung stock firmware?
Thanks.

Unlocked Samsung Stock Firmware on AT&T Note 8 Questions

Hey All -
As a newbie I'd like to get some clarity as it's a little unclear to me still....I almost purchased a Note 8 from my carrier (AT&T) and
prefer to remove all the bloat so I wanted to get more details before finalizing my purchase. So the phone would be a Snapdragon CPU and carrier locked - which isn't a big deal for me. My goal would be to install pure Samsung firmware and be able to receive updates from Samsung without waiting for the carrier and remove the bloat.
Btw, I did a forum search and found something close but it was a Verizon related topic.
So my questions:
1) Is this possible without tripping knox?
2) What is lost between stock firmware and carrier firmware other than bloat? I'm assuming all the bands and network features keep working as before.
I'm also assuming since the IMEI number is an ATT branded phone Wi-Fi Calling and VoLTE is not lost or is CSC uploading still required with stock firmware?
Thanks!

There isn't much bloat on them anymore these days. Yes, anything you do will prompt Knox. You can disable almost any app now without rooting the phone, so no root is needed at all for that purpose. Just disable it in settings, or if not allowed on a specific app to do that, just install "BK Disabler" from the play store.

I've flashed the stock rom through Odin and fairly certain it didn't trip Knox or any issues that aspect since my company verifies Knox compliance.
With the stock rom I get my hotspot through AT&T which I couldn't on the AT&T rom, I just used the tutorial on here to flash it with no problems. I will get the updates for the U1 when it gets pushed down and have got security updates just fine. You can disable a lot of apps already though on AT&T stock
Oh and you don't lose anything other than the AT&T pre installed garbage that nobody really uses
**edit just checked and yes I'm 0x0 on Knox so it didn't trip it

Yes you absolutely can install the unlocked 950U1 firmware on your ATT device. All the 950U devices are identical and the firmware is 100% interchangeable and will NOT trip KNOX. I'm running for T-Mobile firmware on a Verizon Note8 right now. KNOX is only tripped when you flash unofficial firmware, such as custom recovery and ROM.
There's really not much of a reason to do it though. Theres very little bloat on these, and you will lose VoLTE and WiFi calling by flashing the unlocked firmware.
But if you still want to flash the unlocked firmware, follow this post:

Did you guys who flashed stock firmware get stuck with the 80% battery issue? Cause I thought about it just to get Oreo early but I don't want to lose 20% of my battery. Also have any of you tried to flash a regular update to a carrier note 8 using the update from SD card option?

You only lose battery capacity if your root a snapdragon. Not just by flashing official firmwares.

Okay I was confused. Thanks for clearing that up for me. I hope they find a fix for that eventually.

Note 9 N9600 SDM845 HongKong Version to N960U1 firmware ?

Hello,
I have a Note 9 N9600 SD845 HongKong Version, I am using Lyca Mobile sim( Tmobile MVNO) with it .
I have gone through this forum and could not figure out if its possible to install the N960U1 firmware on N9600.
If yes, will it activate all the tmobile bands on N9600 ?
I also have a ATT unlocked note 9 N960U, I have flashed it to N960U1 successfully using Odin. Is it the same process for N9600 ?
Thanks in advance
I there, I have the same phone model and the conclusion that I made was that you can't just flash the u1 firmware like how awe are used to. I had to root mine in order to install tmb software. I then had 4g Lte and wifi calling, but before you root look at what you may be missing out on. It is usaully stuff dealing with knox i.e samsung pay, secure folder, etc.

Unless you flash the official Samsung software using Odin, you will not be able to install OTA updates. But from my understanding you can't flash USA U1 firmware onto the Hong Kong/International N9600 Note 9. The bootloader will only accept firmware for their respective models. All U.S. Note 9's can flash any of the carrier versions or the unlocked U.S. firmware, but you can't flash the international N9600 firmware... and vice versa.

Canadian version note 8: what roam should I flash?

Hey guys...
Just got a used note 8 and I flashed it to Android pie with one ui (N950USQU5DSD3). Now the problem is that I can't update the phone via OTA. When I click software update its sticks at "registering device" with a spinning circle. Now I suspect that it's a U950W (my friend said it was locked with Bell and unlocked after the the plan ends). Now on sammobile.com the lastest firmware for note 8 (N950U) is N950USQS5DSF5. And I don't want to flash back to the Canadian version (n950w) because it doesn't get update as often as the n950u or n950u1 and it comes with a lot of Bell bloatware.
So for me to get a OTA without any bloatware, which version should I flashed?
Many many thanks.

install Verizon "Advanced Calling" on G973U1 firmware?

Verizon is my carrier and I am upgrading to an S10 from an S7. I bought a new S10 loaded with the first Verizon version of Android 10, G973USQS2CSL1. I want to get rid of the bloatware and go back to Android 9. My plan is to flash the U1 firmware, G973U1UES2BSIV, using all 4 of the U1 files. Then flash the Verizon CSC file from this firmware, G973USQS2BSIV, so I can get the "Advanced Calling" for Verizon. I was going to try to do that on my S7 but never got around to it. Here's a thread I created on the S7 forum that said that's what I would need to do to run the unbranded firmware on the S7 but also have Verizon's Advanced Calling (wifi calling, video call, hd calling). https://forum.xda-developers.com/galaxy-s7/help/install-verizon-advanced-calling-g930u-t3997525
I noticed the S10 Verizon firmware now has a 5th file, a USERDATA file. Will I need to also flash that?
I wanted to point out, my new phone is currently locked, but Verizon automatically unlocks it after 60 days. https://www.verizon.com/about/consumer-safety/device-unlocking-policy Will it be a problem if I flash the unbranded firmware on a phone that is still locked? Since Verizon is my carrier, I will obviously be using a Verizon SIM card.
Thank for the help.
You can flash any firmware to your phone as long as it's for the U or U1 models as the "U" means Universal. Bought a phone from AT&T? Flash the Sprint or T-mobile firmware without issues. Same for Verizon and other U.S. carriers firmware.
Flashing the unbranded firmware will get rid of the bloatware, but will also get rid of other features like wifi calling, advanced calling, etc. The user data file is just all of Verizon's bloatware and info crap.
As for going back to Android 9, you can do that as long as you're still on the v2 bootloader. If you've upgraded to the v3 bootloader via OTA, you won't be able to return to Android 9.

I'm on v2 bootloader. Have you heard of flashing the VZW CSC file on top of the U1 unbranded firmware? Apparently people have done it on older devices, like the S7, that only took the 4 files when flashing. I'm trying to run unbranded firmware but still have the Verizon Advanced Calling (wifi calling, HD calling, video call).
Okay if you're on bootloader v2 then you can go back to Android 9. I haven't heard of flashing the carrier CSC file with the unbranded U1 firmware. It might work or might also brick your phone.

Bought AT&T Unlocked Phone, looking for correct ROM

I'm currently living in Japan, but will be moving back to the US in a couple months, so I recently bought a refurbished Galaxy S20 FE 5g that claimed to be unlocked from the US and had it shipped to Japan.
It works fine with my Japanese sim, but came with AT&T bloatware installed and the model number is still SM-G781U. To my understanding, an unlocked phone should have a '1' after this, signifying that it's unlocked. Because of this, I don't get OTA updated and am still stick on Android 10 and One UI 2.5. So I figured I'd learn how to flash it and do that. It says the CSC is G781UOYN1ATIG, but then when I go to Service Provider it says ATT/ATT/ATT.
Could I just flash the firmware for the SM-G781U1, CSC: XAA onto it and be able to have a fully unlocked and updated phone? Sorry I'm a bit new to this and don't want to brick my phone. Thanks!
I did the opposite (from SM-G781U1 to SM-G781U) and worked with no problems. I needed ATT Wi-Fi calling that worked only with the ATT firmware when I was on Android 10. I suggest to do a factory reset when switching between branded and unbranded but (in theory) you should keep your phone data if you flash the HOME_CSC file.
