Trouble w/Verizon Flash Firmware

Hello, new to this forum. I read through almost all 100+ pages of posts and didn't seem to find anything about my issue.

I started with an AT&T Samsung SM-G975U straight from AT&T.

I purchased an unlock code from a third-party EBAY service that allowed me to unlock the phone to be used on other carriers, and moved from Straight Talk (BYOD for 1 year with no issues) to Verizon (I switched because the company I was hired for offers full stipend of $75/month for using Verizon service only). Calling and messaging was very funky with Verizon network using their BYOD SIM card so I researched how to flash the firmware and came across this thread.

After figuring out a gameplan for flashing my AT&T S10+, I download Odin 3.1.14 PATCHED and also subscribed to SAMMOBILE to acquire latest firmware available for an S10+ with Verizon bloatware. I proceeded to wipe, reboot and flashed it to SM-G975U1 and inserted the SIM upon reboot, finished setting up the phone and downloaded all the necessary updates until it was for the most part, ready to use. Then I put it into download mode and flashed it again over to SM-G975U with Verizon bloatware (all obtained from SAMMOBILE, and it was a February 2020 firmware) and everything seemed to go flawlessly well.

My issue i am having now is trying to get Basic Visual Voicemail to work. This was the main selling point to me to switch my personal device to Verizon network over just getting a 2nd company phone. I get so many spam voicemails (10-15 a day) and it takes literally a good 10 minutes of my time in the evening to delete these spam voicemails every single day.

So i got the most recent firmware, most recent available bloatware from Verizon, but my "red icon Voicemail" application that came with the bloat does not allow me to set up Visual Voicemail. It just gives me a single option to call *86 to connect to the standard voicemail. I'm wondering if I did something wrong, the phone boots up with all the Verizon "menus/bloat/VoLTE/icons", but no options or setup for Visual Voicemail.

I called Verizon and they said that my IMEI is still showing this as an AT&T branded phone, and they cannot assist me unless I buy a new phone from them, just because the IMEI won't let their system to enable Premium Visual Voicemail. They have added Basic Visual Voicemail to my enabled addons/extras but told me that I would have to troubleshoot or figure out my end of the problem myself. So I'm just curious if anyone here has found a workaround, a different method of flashing, anything to help me get my visual voicemail to work.

Again: I have an AT&T branded Samsung G975U that has been wiped, then flashed ---> 975U1 unlocked ----> 975U Verizon bloated, updated, and working correctly but missing Visual Voicemail.

Thank you for reading.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Many times, carrier-specific features like that are dependent on IMEI provisioning. So if your IMEI isn't originally from the carrier that you're using, they'll know. If they're telling you that the only solution is to use a Verizon device, then that's what you'll have to do. (Of course, there is another option, but talking about that - at least publicly and openly - on XDA is frowned upon)
[Samsung Galaxy S10+ Guides, News, & Discussion] baknblack:
Same here, ATT phone. My work around google voice. Just grab google voice from the play store, run setup, pick a GV number. Then set GV up to use your carrier for phone calls. Next go to your verizon account and set up call forward busy/no answer to forward to your GV number. Free VVM with transcription!!!!

Now, help me, lol. I've been out of the flashing/rooting game for years. I know how to get the patched ODIN and use it. I'm just having trouble figuring out exactly which firmware package I need to get.
[Samsung Galaxy S10+ Guides, News, & Discussion] Mickalback:
Wow I set my G VVM last night and I'm impressed. That was a great work around. Beats having to buy another device!

The most recent one I found was on SAMMOBILE. I subscribed for the 7euro plan and downloaded the 5 files for my phone model, and picked my carrier. Verizon only had February updates but just look for something recent. You can download for free but they kind of lock your DL to 115kb/s or so, so you are looking at an 8 hour download.

If you are doing a full carrier wipe you should download the U1 package first and do post #25 instructions.

Hey, I have an S10+ on TC9. Can I downgrade that to TB3 or any earlier one? It seems TC9 is b3, I'm not sure when b2 ended and b3 started. I'm trying to flash it from Sprint to Verizon.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Yep. TA3, TB1, TB5, or TB6 are the bootloader 3 versions that came out before TC9
[Samsung Galaxy S10+ Guides, News, & Discussion] 1337haXXor:
Awesome, so I can just flash any of those, then follow the instructions on post #25 to change it over? This whole "U" thing that newer phones are doing is kinda nice. :)

Thanks a bunch!

Save me from android 9!

so i've been using a S10+ that i got from a seller on amazon that said it was an unlocked At&T display model and i got it working on metro over a year ago and been working great since. Problem being i've never been able to get OTA updates and i really want to get to android 10. Now when i connect the phone to Smart Switch on windows i get -

" you device software is up to date (SD3 ATT)"

and then above its on android 9 version 9.0.0...

Model for the phone is a SM-G975U

I havent used Odin in almost a decade it feels like (Galaxy S3 custom Rom) and i'd like anyone to point me to the proper method and possibly a source of where i need to get the proper install files for android 10 for Metro PCS. Can't find much if anything anywhere besides XDA forums being of any help.

any guide or tutorial and links for what i need to do would be a life savers please thank you in advance will be checking on this thread daily :D
[Samsung Galaxy S10+ Guides, News, & Discussion] 1337haXXor:
Hmm, I must've messed something up somewhere. I wiped the phone and flashed the BL/AP/CPC/non-home CSC but the phone never prompted to switch carriers. It booted to the setup screen and I rebooted and flashed everything but with the vzw USERDATA this time. At the end of the flash, it failed in Odin, saying something like "sw rev check fail userdatafused 3 > binary 1."

I used TB3 for the main stuff, but for the vzw USERDATA I used the SBA, which it seems is an older one. Do you have to match the binary level for the rom AND the USERDATA? If so, I only see b1 and b2 USERDATAs for vzw on your OP.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Yes, of course they have to match. If you have binary 3, you can't flash ANY files from any older binary. Anyone can obtain the latest Verizon firmware at any time from SamFirm or Frija

A complete guide?

Hello,

I know the following question has probably been answered somewhere, but I couldn't find it. So I would really appreciate an answer.

I have a locked AT&T S10 plus (G975U) which I bought through bestbuy the day it was launched. I have recently realized that the phone has never received OTA updates so the Android version is still 9 and the security patch level is Feb 1, 2019 (you can tell how tech-savvy I am). My interactions with AT&T regarding the problem have been nothing but frustrating, so I decided to manually update the OS. I have read half of the posts on this thread and a few other sources, but am not still sure how exactly to do it and where to start from. Could anyone please explain the whole process in layman's term?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
As stated in the OP, this is not intended to be a "beginner's guide to Odin flashing"-type thread. There are already plenty of those here on XDA.
[Samsung Galaxy S10+ Guides, News, & Discussion] Lavman72:
Hi,

There are many, many posts on this problem..some by yours truly. I have had the same issue with my last 2 devices that I purchased directly from Samsung (Note 8 and Galaxy S10+, although they are the AT&T models. I've had to update via Odin in order to get the most recent updates. There are many forums on how to go about this here, and on Youtube. Here's a link to a basic guide:

https://xdaforums.com/showthread.php?t=1372414

Once you've done it a couple of times, it's less daunting.

Good luck
[Samsung Galaxy S10+ Guides, News, & Discussion] 1337haXXor:
Okay, I finally got around to trying again (it's a family member's phone, he came by again today). I downloaded the newest U and U1 firmware with Frija (and the VZW USERDATA) but at step 2, after inserting the SIM on the U1 firmware, it gives me an error of "Invalid SIM Card" and does not prompt to restart. He's using his currently active SIM card on his Verizon account, does it have to be a new, inactive SIM card? Additionally, on this U1 firmware, it still shows "Sprint" under the "Brand" section in the phone's settings. Is this normal until I switch it to Verizon, or is it supposed to say something like "unbranded?"
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
"invalid SIM card" means that it's still SIM locked to its original carrier, which sounds like it's Sprint
[Samsung Galaxy S10+ Guides, News, & Discussion] 1337haXXor:
It is indeed Sprint. I've read through a good chunk of this massive thread, did I miss something? Does it have to be unlocked, or are there special issues with the Sprint version? Apologies if I misunderstood something. Is there a different process for unlocking it from the carrier? I thoughts that's what *this* process was doing.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
Yes it needs to be carrier unlocked, the phone.
[Samsung Galaxy S10+ Guides, News, & Discussion] 1337haXXor:
I see, I didn't get that from the thread, sigh... The phone no longer even has the Sprint SIM card, does that mean I'm SoL?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
No. Flashing U1 firmware doesn't magically SIM unlock a phone. The SIM unlock resides much deeper than firmware level

Not necessarily. If you don't meet Sprint's requirements, a 3rd party professional business (such as the one that I own) can do the unlock for you
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
Maybe your present carrier will unlock it so you can use it on their network. Then you can load the U1 software. There are paid services that will sell you the unlock code based on serial number of the device. (IMEI)

---------- Post added at 01:59 AM ---------- Previous post was at 01:57 AM ----------

No but you need to get the sim unlock code based on the IMEI of the phone
[Samsung Galaxy S10+ Guides, News, & Discussion] 1337haXXor:
Well apologies again, gentleman, I was unaware of that. Thanks for your time and patience!
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
You're welcome. We've all been there. :svetius:
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
1. Carriers can only unlock their own devices. So Verizon can't unlock a Sprint device

2. Sprint phones have never used unlock codes and never will. SIM unlocking a Sprint phone is much more complicated and difficult than a simple little code
[Samsung Galaxy S10+ Guides, News, & Discussion] Lavman72:
Has there been any new updates for the ATT model? I'm still running TB3, with the Feb 1 security patch.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:

[Samsung Galaxy S10+ Guides, News, & Discussion] Lavman72:
Thanks? I know that there has been an update, but for whatever reason, I've never gotten any OTA updates on my S10+. Long story, and there are many, many others who have had the same issue. So I've had to rely on the Odin files/process to update my phone. Which, as you can imagine, isn't great. So was really hoping the new files had been made available.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
And you still subscribe to AT&T? Call tech support and customer disservice and complain. Here's a thought switch to U1 and maybe another carrier. It's what I had to do.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
New files are always available. You can flash any U version at any time
[Samsung Galaxy S10+ Guides, News, & Discussion] Lavman72:
Yes, unfortunately I do. I've thought about leaving. But have a family plan that has a pretty good price and data. I'm sure someone like TMO could offer something similar, I just haven't looked at their options.

To answer your question, I have been on numerous calls with Customer service and tech support. Get ping-ponged back and forth from one to the other. And it always ends in the same manner. AT&T blames Samsung, and Samsung blames AT&T. I've even had both Samsung and AT&T on at the same time. That didn't go well at all. From what I can tell, this all stems from the fact that I bought the phone directly from Samsung. Even though it is the AT&T specific model. I did the same exact thing with my last phone (Note 8) and had the exact same issue - not a single update. I do enjoy AT&T's caller ID/blocking and Spam feature. Other than that, I don't have a strong tie to their version of the software.

I'm all ears for a possible solution to this. I'd prefer to just take OTA's like mostly everyone else.

I wonder if this is worth a try:

[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
I went back and forth with both until I left and went to another carrier that values my business. Samsung doesn't give a sh*t about their customers in the North American market. Their products for the rest of the world are rootable without lose of warranty. They remind me of the student that told the teacher "the dog ate my homework".

The ball is in your court

---------- Post added at 07:57 PM ---------- Previous post was at 07:54 PM ----------

T-Mobile has the same feature set. I too started with AT&T equipment went U1 and followed the instructions in the OP.
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
When you originally got it, was it a U model with all of AT&T's bloatware? Or was it a U1 model?

As long as you don't trip Knox, yes, you don't lose your warranty. Trip Knox, and you're SOL
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
U model from AT&T with the full complement of bloatware. Backed it up followed the instructions and inserted the Tmo sim, and it's been smooth sailing ever since. And I save money monthly. AT&T is not the real AT&T it's Southwestern Bell in a big girl's dress
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
LMAO.

So it came SIM unlocked from Samsung, even though it came with all the bloatware...?
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
No I demanded the unlock code and they were forced to give it to me, as per the terms of service. If you are current on your account by law the carrier can't withhold it. That's assuming you own the unit outright.

---------- Post added at 08:56 PM ---------- Previous post was at 08:55 PM ----------

It came from AT&T not Samsung
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
It's actually a common misconception that it's an actual law. It's simply a basic agreement that all carriers have loosely agreed to adhere to, issued through the FCC. There is no actual law on the books dealing with this sort of thing.

The only thing that I can think of is that Samsung had its own specific batch of IMEI/serial numbers, separate from the ones issued to carriers. And that's causing AT&T to deny updates. They're incredibly anal about that crap - they'll even deny OTAs to a device running on one of their own MVNOs. They'll also deny it if an inactive AT&T SIM is inserted - it can't be done just over wifi
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
My company worked with them with U verse and all of my employees had to have AT&T service and phones. I had checked with them and the FCC (old FCC) and they said that if the phone is free and clear the carrier has to sim unlock the phone. They tell the public it's not mandatory.
[Samsung Galaxy S10+ Guides, News, & Discussion] Lavman72:
Yes, it was a U model with all of AT&T's bloatware. I own the phone outright at this point.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
If you're still on AT&T politely ask for the code. Then run like hell

Contact tech support for the code not not customer service

Verizon to Unbranded

Thanks a bunch for posting this. Recently bought a Samsung Galaxy S10+ and the information here has been invaluable. I am trying to install the G975U1 Firmware on my Verizon phone. I want to remove all the stock bloatware. However, when I followed your instructions on Post #25 it did not work. I still get the Verizon logo at the beginning of startup and all the accompanying bloatware. My phone currently has the latest firmware that I downloaded from Frija but I installed without the user data but Verizon remains. Any suggestions?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
If you're trying to install U1 firmware, then why are you flashing U firmware?
[Samsung Galaxy S10+ Guides, News, & Discussion] TheEvilDead:
I'm pretty new to this whole process and maybe I'm just confused. My understanding was that if I installed the software from Frija without the user data that would give me a unbranded stock firmware install. If I'm understanding your file system nomenclature correctly you're U1 firmware has Android 9. I was attempting to keep Android 10 well removing all the Verizon bloatware.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
No U1 is unbranded and U is carrier specific if you purchased the device from your carrier. U1 is not Android version specific that will be your decision which version you ultimately want. Let's not confuse the issue and the method.
[Samsung Galaxy S10+ Guides, News, & Discussion] TheEvilDead:
So then my question is how do I install an unbranded firmware on my phone with Android 10? The provided firmware only appears to be Android 9. Is there a place where I can download unbranded Android 10 firmware for my Samsung Galaxy S10+?

Again, I apologize for my ignorance and I'm really appreciative of any help that can be provided.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
First don't apologize at some point we were all where you are. Read the posts from the OP download the correct ODIN and go slowly following each post to change from U to U1. Step 1- First backup your phone so you don't loose your personal data. After you flash then insert the carrier sim you want to use and reload the backup data and the phone should be where you want to be...
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
The OP states clearly that the latest version can be obtained at any time via SamFirm/Frija. If you want U1 firmware, then you need to be typing in the U1 model, not the U model
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
He just doesn't get it. This forum i for instructions and help for those who have the desire to do things for themselves
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Stop.

Don't sit there and tell him "don't apologize, at one point we were all where you are now", and and then in the next post, rag on him for not understanding.
[Samsung Galaxy S10+ Guides, News, & Discussion] sw1173:
Your forum your rules. I wasn't ragging on him just trying to bring him into the fold.
[Samsung Galaxy S10+ Guides, News, & Discussion] Lavman72:
Gonna try and go through these steps to see if that resolves the non-update issue with these phones purchased directly from Samsung.
[Samsung Galaxy S10+ Guides, News, & Discussion] Greatone007:
Can you go straight from the SAT version to the newest version of firmware or do you have to increment up?
[Samsung Galaxy S10+ Guides, News, & Discussion] iBowToAndroid:
Incrementing is only needing if you're installing update.zip's from Recovery mode. When it comes to Odin, just flash whatever version you want to be on (as long as you're not trying to go backward in bootloader versions)
[Samsung Galaxy S10+ Guides, News, & Discussion] TheEvilDead:
Brandon to Unbranded

Didn't mean to cause any strife with my questions. I did some more reading and I was misunderstanding the process. After going back to Frija I downloaded the correct G975U1 firmware.

However, I was then confronted with a "FAIL! SHA256 is invalid" error. Using this forum I was able to determine that I needed Odin3 v3.13.3_3B_PatcheD. Once I downloaded it everything went quite smoothly.

I would add that I had some difficultly locating the correct Odin version. There appears to be a lot of non-official versions of what I needed out there and as a result I download quite a few versions until I located the forum linked below.

Thanks again everyone for your patience and help.
