You'd have a point - if I had uploaded the tar files themselves. But they're zipped up. If the zip gets corrupted during download, it won't extract.
[Samsung Galaxy S9+ Guides, News, & Discussion] nugzo:
Which is why i thought they were corrupt, since winrar or file explorer wouldn't extract them. winrar normally extracts everything. I just downloaded 7zip on a whim just to try. half the posts in this thread are "wont extract" posts.

I have Samsung unlocked version (G965U1) ATT/ATT/XAA with G965U firmware installed and ATT user data. Going for ATT/ATT/ATT. I remember something about this in the s7 threads a few years ago. There was a combination to get ATT/ATT/ATT and i thought it allowed wifi calling to work. It's on my phone but says ooops when i try to enable it and for someone who can make account decisions to call their 800 number. anybody know anything about converting unlocked to full ATT to make use of ATT features?

Unlocked firmware auto updates to use any carrier sim card settings has very little bloat compared to at&t, and you still get updates, most likely faster than most carriers.

I just switched my unlocked S9+ from Bestbuy (G965U1) to VZW firmare (G965U), everything is working now, (wifi calling, voice HD,etc). Just download the G965U firmware from VZW and flash it with Odin 3.13.1
[Samsung Galaxy S9+ Guides, News, & Discussion] monsterlag:
Here is a quick guide

Proceed with Caution. This is a firmware flash using Odin and will not trip KNOX.

* Download Mobile Driver for Samsung phones and install it

* Download G965 U1(Unlocked Model files) from here

* Extract using 7-Zip(WinRar will error out)

* Download the PatcheD Odin from here

* Factory Reset the phone and remove your Google Account if you have already set the phone up.

* Assemble all required files on Odin

* Put the phone into Download mode by holding down the Bixby Button, then the Volume Down button and then the Power Button. Hold all 3 buttons down till a warning page appears, proceed by pressing the Volume up button

* Connect the Phone to your PC using the factory cable

* Press Start on Odin

* The whole process should take about 5 minutes to finish.

* The phone will restart twice and voila you will have an unlocked S9+ with no carrier boot logo or bloat.

Why do you not flash userdata? I flashed it and I don't see any issues? Should I re-flash without userdata?
[Samsung Galaxy S9+ Guides, News, & Discussion] gamer765:
You can safely flash the USERDATA. Remember, that's where the carrier bloat comes from anyways, so if you keep the carrier USERDATA, you might get the bloat even on U1 firmware. Haven't gotten around to unlocking and converting my AT&T S9+ yet.
[Samsung Galaxy S9+ Guides, News, & Discussion] monsterlag:
I am not sure why I said don’t flash Userdata, Ignore. I flashed without it on the ATT phone and there was no bloat.
[Samsung Galaxy S9+ Guides, News, & Discussion] nugzo:
Its the u1 firmware, but your sim should still be locked, If you have an ATT s9 and flash the G985U1 unlocked firmware your phone will still need an ATT sim, another carrier wont work. its still locked just no bloatware and you miss the carrier specific features like wifi calling, volte, etc,

nothing to do with bootloader.
[Samsung Galaxy S9+ Guides, News, & Discussion] NotATreoFan:
I had no issue flashing the U1 firmware to my TMO device, but with or without the USERDATA, some features are missing. I didn't have the advanced messaging toggle under Messages, and when I restored my texts from the cloud, any advanced format messages did not restore.

Reverting to the standard firmware w/ USERDATA now to test.
[Samsung Galaxy S9+ Guides, News, & Discussion] iunlock:
As I was reading through all the pages, I was starting to get curious about this for my T-Mobile S9+ and sure enough I see your post lol... Thanks for testing this...

I usually flash the U1 firmware on my devices like on my Note 8. When flashing the U1 here did you add all three files in Odin and in the 4th slot add the TM csc?

I'm debating on whether to just stay on the stock ARB7 T-Mobile firmware or flash the U1 as I have the phone pretty debloated right now as it stands... hmmm... ie... is it even worth it in this case to flash the U1? (I also won't be taking any updates either so it'll stay put on the current ARB7)

G9650 from Telcel... can I debloat with U1?

Sorry if the question has been answered before (maybe with s8 phones) but, my last Samsung phone was S4... so... I remember how to flash with Odin and such but I'm still having doubts.

I have an unlocked SM-G9650 from Telcel México (which I use with another carrier, AT&T México) and I REALLY hate the boot animation and the bloatware it has... This model has the Snapdragon 845 (single SIM) and appears to be identical to the G965U1 in nearly every aspect except from the model... so, do you think I could use this firmware U1 to debloat? And if so, how could I? I'm a little confused by the userdata thing specially because of the last couple of posts hahaha

Telcel nor AT&T add any cool service like Wifi Calling or such, so I'm just interested in debloating AND mantaining OTA, maybe from unlocked US phones.... thank you!

I want to go from TCE (G9650) to XAA (G965U1) for example... both are Snapdragon as far as I know.

[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Yes, but only uf your Verizon firmware contains the v1 bootloader. If you have updated recently, your devices bootloader would more than likely have been updreladed to the v2 bootloader.

Does anyone know if I can buy a new US Cellular version of the S9 plus and then flash the VZ firmware and use it on Verizon network?

Right now samsung.com has the lowest price with US celluar, so this route would be ideal.. but I don't want to buy it and then find out I need to switch carriers or the device is locked to US cellular.

thanks!
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Although I am not too sure if the US Cellular firmware has had the bootloader Verizon updated. Most phones out of the box have not been updated. If you buy one and it has the v1 bootloader, then you can foash it to the U1 firmware and then to the Verizon firmware. The Verizon firmware though has the v2 bootloader when fully up to date. Once you upgrade your bootloader, you won't be able to make fpash back untip the U1 firmware gets the v2 bootloader.
[Samsung Galaxy S9+ Guides, News, & Discussion] FingerFish:
So if the phone has the v2 bootloader out of the box, does that mean I'm locked to US cellular?
[Samsung Galaxy S9+ Guides, News, & Discussion] dannyHD2:
Yup, unfortunately. Until they release the u1 on bootlader v2 there's no carrier switching if you're already updated to one of the newer v2 bootloader firmwares already. I'm still waiting for the v2 bootloader for the u1 to be released so I can swap my att to tmobile. Hopefully soon....
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
I meant where did he see that ARF4 was official. Typically the only way an update passes safety net is when a carrier releases that version. I use Google Pay for my watch, so I need updates that pass safety net. After I posted the question, I found Verizon's website shows ARF4 as being the latest (they skipped ARE6 according to that page). So I'm guessing ARF4 now passes safety net. I'm planning on trying it in a few days.
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Locked, as in SIM locked? It basically means you are stuck with the firmware it comes with until the U1 is updated. Ask the store when they got their stock. If it is at keast a coue of mo ths old, then it more than likely will have the v1 bootloader firmware. Even if the stock is newer though. It still mightbhave the v1 bootloader because these devices sit around warehousss for periods of time before making it to the store level.

ARC6 and ARE6 had issues. Verizon was smart to pass those over.
[Samsung Galaxy S9+ Guides, News, & Discussion] FingerFish:
Thats a good question - if I'm stuck with the US cellular firmware, can it operate on VZ? I can't check beforehand since this is a purchase from samsung.com
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
Cross-flashing firmware does not SIM unlock or SIM lock the device. You do want to make sure it is SIM unlocked before flashing to save yourself the hassle of trying to get it done after.
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
I was wrong, some Verizon customers started getting. ARE6 on June 5th, but they halted that rollout. June 15th Verizon started rolling out ARF4. That info while not on SamFirm, is on the Verizon page.
[Samsung Galaxy S9+ Guides, News, & Discussion] AmazingTrans:
I currently have a S9+ on TMB : Baseband V: G965USQU1ARBG.

Just inherited the phone from my wife who is switching over to iPhone. boo.

Anyhow, I am a vzw user, and when i travel occasionally, i use my work TMB sim card whenever I can, since it can work in many countries.

1. Would it be best, if i use the G965U1_RB7_1.zip f/w ?

2. Does the U1 allow me to swap sim card between vzw and tmobile?

3. If i were to use U1, will the phone check for updates depending on whichever simcard i use? or it will check from samsung website?

Flashing questions

1. Right before I flash the phone, does it matter if i have any sim card in the phone at all?

2. If i want to clear the phone app & data, should i run the CSC_OxM independently of itself first, then run all the files including the HOME_OxM? Or can i just run the CSC_OxM?

3. If i use the U1, will hotspot work for my vzw & tmobile ?

4. If i use U1, and decide to stay on the vzw network, do i have to apply all the VZW radio rom patch etc , if any (Brain still back in '12, when i patch my galaxy nexus with other ROMs).

Thanks!
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
You must SIM unlock your device if you intend on using it on more than one carrier. Simply cross-flashing does not SIM unlock your device U1 is more friendly towards every US carrier because you essentially end up with what you need based o the SIM installed, except a lot less bloat.

It helps to have the SIM you are going to use in while flashing. This will download the APN and other settings needed. If you don't have a SIM in when flashing, then you will have to manually imput your APN, etc.

When flashing to U1, a full wipe is the best way to go. Personally, I would suggest never using the HOME_CSC. Flash everything at once. If you split stuff up, you are going to create a lot of problems.

Why people think carriers actually create uodates is beyond me. They do approve updates but almost never create them. When an update is released after being allroved bybthe carrier. That update was still created and released by the manufscturer. You will get updates for which ever firmware you are on.

I don't personally use hotspot and am nkt a Verizon customer so I don't knlw. Worst case scenario, you will have to create the hotspot APN manually.

There are no radio patches to flash. If you flash a U firmware, you will have the bands needed for that oarticular carrier. If you flash to U1 or W, the bands availBle are based on the SIM card inserted.

I have a big regret from buying my S9+ in USA, my version is SM-G965U1 (Unlocked), but i live in Brazil and the brazilian version is SM-G9650 (also using snapdragon 845) . My Samsung Pay doesn't work with brazilian credit cards, just american cards works. Searching for brazilian firmwares on sammobile, i saw those versions

SM-G9650 Brazlilian ZTO Firmwares

Date	Version	PDA	CSC

2018-05-28	8.0.0	G9600ZHU2ARE6	G9600OWO2ARE6

2018-04-25	8.0.0	G9600ZHU2ARD3	G9600OWO2ARC6

2018-04-01	8.0.0	G9600ZHU2ARC6	G9600OWO2ARC6

My question is, there is any hope to those firmwares could run in my SM-G965U1 without brick? any master here?
[Samsung Galaxy S9+ Guides, News, & Discussion] rmarinella:
I believe the firmware will flash and boot, but the Brazilian firmware is for dual sim, so not sure how the sim portion of the equation will work out for you. You could end up with no signal. However, you should be able to flash black to the SM-G965U firmware if it won't work. You won't be able to flash back to SM-G965U1 though. Anyone else before armindoriedel takes a chance??

Hello. First of all great work! I've been reading posts for days trying to get a real answer to my question (and I may not have read enough forum posts). But here's my scenario:

I bought the unlocked U1 version phone from Samsung. I have ATT in the US. I want to flash to U version to get those advanced features like wifi calling (4g service in my house is horrible). I tried flashing ARBG for U and it didn't take. I just want those features.

The links I found for U firmware on RB7 only let me download from the Netherlands which won't complete successfully. How can I get onto ATT from my currently OEM-unlocked (U1) phone? Currently on v1 BL

Thank you for your patience in case this has been mentioned somewhere in the 62 pages of posts I've tried to read
[Samsung Galaxy S9+ Guides, News, & Discussion] jcsww:
If it didn'tvtake, then something didn't go right. Get the image from Updato. Yes, their site is slow but the images don't have any issues. Get the modded or patched ODIN 3.13.1. You will need that to convert. Did you have USB Debugging enabled in Developer Options? You need tonuse tye original USB cable or anotuer that will do charging and data on a USB 3 port that doesn't share bandwidtu with others. Do you have the Samsung and ADB drivers installed? Don't use drivers Windows installs!

You must factory wipe to guarantee a successful conversion! I highly recommend doing this before flashing, skip the bulk of the setup just to re-enable Developer Options and USB Debugging. You should now be good to flash. Do not flash any of the HOME files in the ODIN zip! Make sure your AT&T SIM is in the device before you start flashing.
[Samsung Galaxy S9+ Guides, News, & Discussion] cmoney90:
I'm not sure which image from updato to use since none of them are labeled for ATT. I've been seeing that the image doesn't have to be ATT specific, but none of those are labeled for ATT. Should it matter? I searched for SM-G960U and not U1 as that's what is already installed on my phone.

The download I've been trying is from android file host (MN Mobile Guy) and thats the one that keeps failing to download.

USB Debugging was enabled. Samsung and ADB drivers are installed but from Windows originally. No errors during flash so I assumed everything was good except for the correct image.

Anyone have an arf2 to arf4 flashable? On the go currently and don't have access to laptop with Odin, unless mobile Odin still works...been out of the flashing game for a while lol

Sent from my SM-G955U using Crapatalk
[Samsung Galaxy S9+ Guides, News, & Discussion] todd3835:
As previously mentioned they both work on ARF2, but I can confirm both work on ARF4 as well.

Samsung Pay will typically work on any release you see, since they always pass Knox. Samsung Pay verifies with Knox.

Google Pay authenticates by using Safety Net. Safety Net verifies the phone is using a Google Certified rom. ARF5 is not official. It either hasn't been submitted to Google at all, or hasn't passed yet. For instance, ARF4 passed Safety Net before it was released by carriers. When ARF4 initially leaked, it did not pass.

That said, ARF5 doesn't pass safety net as of yet, but that could change (like ARF2 and ARF4 did). If you require Google Pay (I need it for my LG Watch Sport), your best to stick with official updates, unless someone like Venom says that it's passing Safety Net.

Edit: on a side note, even Google doesn't certify their own pre-release roms. If you've ever owned a pixel or Nexus device, and run the developer previews, they almost never pass safety net.
