Well, i just bought the new Samsung Galaxy S6 Edge Plus From verizon because it's "unlocked" for any carrier. But when trying to see if there's any update it shows "Software update is temporarily unavailable. Try Again Later", does it matters if im not using verizon Sim card? thanks.

I believe you do need a Verizon sim card to access the Verizon software update platform. I know that when I de-activate a phone I get that message until I activate it again.
Try Using Samsung's Smart Switch software for updating.
Yu da man!
I had similar prob when I wanted to unroot my S4 "reformat" and after successful I couldn't update via OTA.... so I did it the hard way with Odin and then was happy, stuck my phone in a drawer for almost a year and decided to put it to service...... same problem again!...
After reading this thread, I realized since a new update was not available I'm getting the error whereas I didn't get it before....
I simply took my existing sim card in my activated Note 4 and put it in the S4 and wallah!... it worked! OTA!
My Verizon account didn't change anything because I didn't actually activate, just only switched sims "so no activation charges".... after OTA done, simply switched it back to my Note4 and now I have a fully updated S4 I can give away!..
Thx!
I got the same problem . I have a galaxy s5 virizon wirless.
There is any way to update my phone to marshmallows 6.0 without the computer
Hey Guys,
I've come across my limit of knowledge during the past days.
I purchased this new phone, "Samsung Galaxy S 7".
When I look up the "About phone" option in "Settings", it says, that it's a SM-G930F with android verison 6.0.1.
I couldnt find ANYTHING according to my Build number, which says: MMB29M.G930FXXU1BPIA or that my Smart Switch says, that the software version would be PIA(VZW).
But when I go into Download/Odin-Mode there are the following text lines:
ODIN MODE (HIGH-SPEED)
PRODUCT NAME: SM-G930V
CURRENT BINARY: SAMSUNG OFFICIAL
SYSTEM STATUS: OFFICIAL
FAP LOCK: OFF
QUALCOMM SECUREBOOT: ENABLE
RP SWREV: B4(2,1,1,1,1) K1 S3
SECURE DOWNLOAD: ENABLE
So, both informations are dividing from each other, because the first says it's a SM-G930F and the second says it's a SM-G930V, except that both have in common, that they say system status is official.
But, my problem is, as you can see, it's still marshmallow that is installed on my Galaxy S 7 and in my settings there is absolutely no possibility to update my phone to nougat.
I've tried several things via Odin like installing: Stock firmware for ADB, Nougat firmware for ADB, Stock firmware for VZW, Nougat firmware for VZW
But just nothing worked out.
Most common issues I had with Odin were: "sboot.bin FAIL!, recovery.img FAIL!, Complete(Write) operation failed.", depending on what kind of files I tried to apply, like pit file, AP-File, Home_CSC-File, etc...
Even if i tried to solve it with the most common troubleshoting methods i could find on google, there would be another issue, like a never ending story.
I also tried applying a firmware with recovery mode but there it says: E: "footer is wrong” ,followed by “E: signature verification failed", even if my SD-Card has never been encrypted.
I dont have any idea what to do anymore,
so i would extremely appreciate some help of a pro, who can tell me, what to do exactly.
Thank you!
*EDIT*
I managed to unroot the phone with the verzon nougat firmware but now it won't let me use the phone with a diferent SIM-card than a Verizon's and I'm going to return the phone.
Hi,
I'm facing the exact same problem.
Which Verizon firmware did you use to unroot your phone?
Thanks!

I managed to flash the latest Verizon ROM (SM-G930V_1_20170330100826_87cd9631jd_fac). Now it is obviously branded and I always get a message (after reboot/after ending airplane mode, so everytime the phone connects to a cellular network) that I'm using a non-verizon sim card. Nevertheless, after manually adding the APN, everything works fine, no SIM lock.
Edit: it works even better with this stock ROM w/o branding: updato.com/firmware-archive-select-model?record=EF06A1ED34EB11E7963AFA163EE8F90B
Same Problem
Its showing 930f in my phone information
but when i go into download mode it shows 930v
cant update my phone it's still stuck in ****ty marshmallow
i would highly appreciate any sort of help.. TIA

you have the exact same issue as me. I suggest you review this thread, it would be helpful.
In summation, you have a converted phone. you can flash Verizon's rom if you want nougat. But that didn't help with my network issues.
Same problem
is this phone is not official what's the matter please explain
I'm also having the OP's exact same problem? I thought the phone I had just bought off gumtree was fake. I'm in Australia and noted that the model one the sticker on the back on my device is SM-G930F, the "about" page lists it as SM-G930F running 6.0.1, odin lists the as model SM-G930V, smart switch as PIA(VZW), CPU-Z as having it having a Snapdragon processor and finally the paper instruction manual is for a SM-9300 (China) - WTH!?
I cant seem to figure out which device it was or is ha! I believe it may be a chinese device that has been flashed to american standard. Is the the core point here, are these perhaps all flashed/refurbed chinese models?
Long story short, i'm not having any problems but i want a newer OS like oreo or nougat - if I flash to say SM-G930U standard with XAA (generic, samsung branding), will i begin having network issues in Australia?
Hi, i have been trying to find an answer to this after hours of searching i've come up short and confused.
I recently switched from tmobile to verizon, and i paid off my tmobile s9+ and had it sim unlocked. When i put my verizon sim in it, nothing really happens. either it tells me that it can't register on the network or to insert a tmobile sim card.
I have tried using reset and factory reset. I have also tried the method of holding the volume bixby and power and doing a factory reset, then putting the sim in, rebooting, etc. That doesn't work either.
I see several people trying to go from verizon to tmobile, but i haven't been able to find anyone going from tmobile to verizon, and what method i need to do to get this to work, if its possible at all. Any help would be so much appreciated!

Use Odin to flash U1 and then go back to U. Just leave the SIM in. Don't use HOME CSC.

That still may not help, remember Verizon is still CDMA and the T Mobile branded phone does not have CDMA bands activated and they may not even be on the phone, I don't know. Granted band 13 should work fine, being LTE, but could the sim be looking for a CDMA radio and that is why it is not working?

The hardware is identical for all US Galaxy S9 phones. Any bands that may be missing will be resolved by flashing firmware. OP could also just stay with U1 if they want unlocked, and all bands would still be there.

As per Samsung chat support, I've asked if the dual sim version (international) will work with Verizon. I've also asked the rep if I can switch carriers with a locked phone. They said that essentially, all phones were manufactured with the CDMA and GSM band compatibility, it just needs to be unlocked and the US versions will work on any carrier in the US and the international version (dual sim) needs to be unlocked and it will work with any carrier in any country.
That said, it seems that you're just having an unlocking issue - which is good and bad. I hope you figure this out. Try using Odin 3.13, get the CORRECT firmware for U1 or U(VZW) to flash your phone

Only one small correction to what they told you: The 965F (international), will not have CDMA capabilities. That might not be a problem on some US carriers. But if you can't get VoLTE working on VZW with 965F, then you're dead in the water, since you don't have 1x CDMA calling to fall back on. It becomes a data-only device. I don't have experience with it, but I wouldn't be surprised if the VoLTE doesn't work on US carriers. For GDM/WCDMA carriers, you'd probably be just fine with 965F. Even if VoLTE doesn't work, you'd still be able to call.
Hope this helps.

Step 1
Can you find out the exact model number?
For T-Mobile, it will be one of these :
SM-G965UZKATMB (Midnight Black)
SM-G965UZBATMB (Coral Blue)
SM-G965UZPATMB (Lilac Purple)
The U is the important part, as a previous poster explained that the F models do not have CDMA support (forget what that actually means, just know its necessary for verizon)
Step 2
Next, make sure that the carrier version is correct.
Example: SM-G965UZKATMB
BST Boost
VZW Verizon
ATT ATT
USC US Cellular
ACG C Spire
TMK MetroPCS
VMU Virgin Mobile
TFN Tracfone
XAS Sprint
TMB T-Mobile
XAA Unlocked US
SPR Sprint
CCT Xfinity Mobile
Essentially, you need the firmware that starts with SM-G965U and ends with VZW
Step 3
I'm not 100% sure on how to flash from carrier to carrier but there will be a list of directions. You may need to do some research there to see if it will void samsung warranty (aka 'trip knox') or anything like that, if that matters to you. I think only a modified version of Odin will be able to do this.
Download Odin v3.13.1
Extract the firmware file you just downloaded. You should get 5 files:
AP (System & Recovery)
BL (Bootloader)
CP (Modem / Radio)
CSC_OXM (OXM CSC file, will wipe your phone)
HOME_CSC_OXM (OXM CSC file, will NOT wipe your phone)
Add each file to it's respective field in Odin v3.13.1. Use CSC_OXM if you want to do a clean flash and HOME_CSC OXM if you want to keep your apps and data.
Reboot your phone in Download / Odin mode with the following button combo: POWER + VOLUME DOWN + BIXBY
Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a blue box will show up with the COM port number.
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say 'PASS'. Once the flash is complete, your phone will reboot.

Step 4
To download firmwares, google "SAMMOBILE website: /firmwares/galaxy-s9-plus/SM-G965U"
Looks like the latest verizon firmware is here: SAMMOBILE website /firmwares/galaxy-s9-plus/SM-G965U/VZW/download/G965USQS2ARF4/223287

Hey thanks a bunch, I’ll give this a shot when I get home tonight. It very well may be that the rom I got wasn’t the right one. Other threads I’ve read seemed to indicate that everything was universal now and by having the SIM card in the phone while flashing, it would download the carrier specific stuff automatically. That part at least doesn’t appear to be the case since the phone wouldn’t accept it. But I’ll download some of the carrier specifics and see what happens. Thanks again!
Did you get it to work after all?
Sorry that i forgot to update! I did get it working, but it required a bit more discussion and help on a reddit discussion someone started. I noticed that someone asked this exact question and i pointed him to this thread where he was able to get it working, then helped me with which roms he used, and i got it working as well! I've been using it daily for almost a month now. Thanks so much for everyones help, i hope that if anyone else is trying to do this, between the two threads it can help. Heres the link to the reddit thread https://old.reddit.com/r/verizon/comments/909iag/tmobile_s9_on_verizon/

Awesome gigatigga - thanks for getting back. I'm on the verge of trying this. I owe some money on my S9 plus on t-mobile but before i paid it off wanted to make sure all is good.
How are the speeds? Everything working ok? Thanks again! :good::good:
Edit: I was all set to do this and during the signup - I found out that my imei wouldn't work in Verizon's system so they used one from another phone. He advised that if I wanted to pay for insurance, if I make a claim it could be an issue because the imei numbers won't match up. Seemed like a big red flag to me. So I didn't go through with it. Wonder how others are handling this?
I just switched from the ATT firmware to ARF4 on T-Mobile, but it says there is no update available, while the newest T-Mobile update is ARF7. Does anyone know how to get updates OTA?

Right here bro. You'll need to sign up with Sam Mobile first then download it. It's slow but it'll get there in about 4 hours or so

Can someone help me?
I cannot network unlock a T-mobile Samsung Galaxy 9 plus which has never been active on any plan. When I insert my Verizon SIM card a system notification says "Invalid SIM card. Network Locked SIM card inserted".
I want to bring this phone to Verizon where I have an active plan. I don't have a plan with Tmobile and my friend gifted me this phone. I flashed it to Samsung stock firmware and bought an unlock code from DoctorSim. The code applied successfully however the phone doesn't unlock completely and continues to prompt for the unlock code when I insert the Verizon Sim card. When I called Tmobile they said only a phone active for 40 days on their network can be unlocked using the phone app and that my friend would have to call them to unlock the phone.

I have an AT&T Samsung S9+. OTA says that I'm already up to date and Samsung Smart Switch says that I'm already up to date too.
I've decided to use SamFirm to download my firmware and update it using Odin.
Here are my statistics:
settings > about > software information > service provider SW ver. it says ATT/ATT/ATT...
My model is SM-G965U.
- I don't know what to put for my Region on the SamFirm tool. Do I put ATT?
- If I do go ahead w/this firmware update will it erase all the data on my phone? I just want to update to Android Pie.
- My Samsung S9+ is AT&T unlocked and I'm now on Metro-PCS, will this mess up my unlocked status and what about affect my Metro-PCS status?
- I heard that using Odin can easily brick your phone, are there ways of preventing that from happening?
Please help thanks!

The First Thing You Need To Do Is.... READ, READ AND READ SOME MORE..
At this device's price point.. you don't want an S9+ paperweight.
Please.. learn what you are doing before you do it.. you should feel VERY comfortable with Odin before pulling the trigger..
Go Watch A Bunch Of YouTube's On The Subject.
While you are doing that.. if you are not going to be a "Paid Member" over at Sammobile, you need to start downloading the "USA (AT&T) version of software. I'm doing this as I type this and it takes over 3 hours to complete if you do not sign up and pay a member fee.
If you want your device to have metroPCS features.. you need to flash the U.S.C. software ( What I use on my Unlocked version ) without your sim installed.. reboot.. and it'll ask you to insert your carrier's sim and it will set things up according to that particular sim.. ( Like Metro's Wi-Fi Calling ).
It's strange.. I have the U.S.A. Unlocked Version (U1) and the device is saying it's "Up To Date" with CSA8 software installed.. So, I'm going to just flash F1 and call it a day..
Take Your Time.. And Good Luck!
A Suggestion..

If you have not already flashed anything... my advice would be to download the "USC U1" July 8th F1 software and install that.
Leave your Sim Out of your phone during the flash.. Just disconnect once you get a green "Pass!" and let it reboot.. ( it will take some extra time ) once it reboots.. you should get a message stating to "Insert Your Sim Card and Reboot" .
Being the Carrier-Free version of the software, It will set your device up with MetroPCS 's features... Done.
No need to worry about going with the ATT version... unless you are still using some of it's bloatware..
I bought a s9+ from swappa around February. I bought my mom one from the same supplier a week ago. At first I was concerned that her's had ATT logo until I realized it would change once a tmobile sim was put in. Her's is now SW ver Tmb/Tmb/Tmb. Then I noticed she is at Android 10.0 UI ver 2.0. I am stuck at Android 9 UI ver 1.0
So It seems I was worried about the wrong phone. It is MY phone that can't get updates. My baseband is:
G965USQU7CSK6 which I believe is an ATT baseband. my SW ver is Tmb/Tmb/Att
I tried connecting to smart switch and it says I am up to date. I tried putting in an at&t sim card (that no longer is in service) and smart switch doesn't complain about anything but it still says it is up to date. Doing OTA while using At&t sim card also says I am up to date. I am CLEARLY not up to date. My last update says Nov.1, 2019.
I have used Odin before...mostly for rooting phone. I haven't rooted since the s5 ( where I could take the battery out ). Little paranoid to use Odin considering I can't take the battery out, but with good instructions I will proceed.
Any help on how to update and especially update on tmobile network would be extremely appreciated.
btw I'm in the US and my model is SM-G965U

--UPDATE
I have researched a bit and found that it IS possible to change the firmware over to Tmobile using a patched version of Odin.
I downloaded from
https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
the 3.13.3_3B_PatcheD.zip
I downloaded G965USQS7CSK3_G965UOYN7CSK3_TMB.zip
from sammobile, which is for Android 9
I would love to be able to use HOME_CSC but that may not work. I could really use some hand holding going through this process.
Is this the correct firmware? Should I be using Android 10 firmware if that is ultimately what I want? HOME_CSC or no? I notice they have the 10 version:
PDA G965USQS7DTB1
CSC G965UOYN7DTB1
as well, which is Android 10 for Tmobile. Also, knox ? will this trip the knox counter thing-a-ma-jig?
Thanks

ok, so I bit the bullet and decided to go ahead. I used
odin 3.14.1_3B_PatcheD.zip just to be sure
I made sure my phone was unlocked: yes it changes carriers if I put in different sim. When in Tmobile sim Settings->Connections->Mobile Networks->Network operators , yes it has a search networks button and it eventually comes up with other carriers so....safe to say I had unlocked phone ( but not samsung unlocked ie. SM-G965U not SM-G965U1)
I used the latest android 9 firmware. and I used HOME_CSC ( even though I did a backup with smart switch b4) Everything went smoothly, and I still have my apps and now I can get an ota security patch for it. Will write back once I am up to Android 10. oh, btw I am still at SW ver Tmb/Tmb/Att , but I've got ota updates so I don't care

ok, so I bit the bullet and decided to go ahead. I used
odin 3.14.1_3B_PatcheD.zip just to be sure

I am now at the same baseband version as my mom. Everything worked perfectly. I suggest you go with the least change possible to get to the point that you are able to do OTA updates. For me this was going to the latest Android 9 that they had at sammobile since I was on Android 9 and going with the Tmobile version. I hear the carrier doesn't even matter these days, but I decided I wanted to make sure it was Tmobile compatible so I chose the Tmobile version from sammobile. Happy trails to you in your endeavors. Hopefully you can learn something from mine.
Hey, I really want to thank you for this! I had the same issue and was exploring similar solutions. After several days of researching alternate plans, I was about to give it up as too risky until I found your post - by googling for hints: "SW ver. TMB/TMB/ATT"! You helped me take the dive, and I'm now happily past having a second-hand S9 (sm-g960u) that wouldn't do an OTA update. After a flawless flash, my first OTA request got me to Android 10, (UI 2). now I have a follow-up update scheduled for the wee hours. (And, yes, I'm still at "TMB/TMB/ATT".)
Perhaps like you, I started by investigating the possibility of flashing the UNLOCKED ("U1") firmware. After learning it was possible with the _patchedD Odin, it still scared me enough that I decided on a more conservative approach and followed your exact advice. I especially appreciated your plan to flash NOT the latest update, but the last Android 9 TMB update. That turned out to correspond to the ATT version on my phone, making TMobile either unable or unwilling to offer an OTA update.
History: This is my third used S9. While all were sold as UNLOCKED, only the first had the "U1" model suffix (SM-g960u1). When the second one booted up as a TMobile phone, I felt tricked - but also lucky that I got the right carrier. That's when I learned about the difference in model numbers. As you noted the U1 firmware is factory unlocked - attached to no carrier. When my third phone booted up with a Verizon greeting I figured I could be facing trouble - even though it accepted my TMB sim card.
The seller explained to me that my phone was part of a batch of ATT phones, all "SIM unlocked" using a Verizon sim card. I think sellers of phones with claims to be unlocked should be required to specify whether FACTORY or SIM unlocked.
Hope this great contribution of yours will continue to help others.
