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.

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)

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.

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.

Yep. TA3, TB1, TB5, or TB6 are the bootloader 3 versions that came out before TC9

 

[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!

If your phone doesn't perform the conversion automatically, then yes

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

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.

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?

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.

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:

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

Good luck

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?"

"invalid SIM card" means that it's still SIM locked to its original carrier, which sounds like it's Sprint

 

[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.

Yes it needs to be carrier unlocked, the phone.

 

[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?
