Will an S7 Edge (T-Mobile) work on Verizon?

Hello all,
I want to switch to Verizon but I don't have a verizon sim to test my phone, I just got it unlocked through the unlock app. I've also read this post,
https://forum.xda-developers.com/tm...izon-galaxy-s7-edge-t-mobile-network-t3399618
but there is no confirmation if he found a solution.
any feed back would help.

Well i live in Mexico, but i own a galaxy s7 edge from tmobile and to try nougat i installed first the Verizon version, and it work well, the only issue was to setting the data configuration, now i use the At&t nougat and everything still even more perfect (the verizon nougat have a lot of little bugs)

Using a Tmobile S7 Edge going to Verizon won't work cause of a few reasons.
1. TMOBILE S7 and S7 edge are not built for CDMA networks that uses certain bands and network. Along with the security of CDMA networks.
2. There is no band 13 on tmobiles S7 and S7 Edge. Even you were to unlock it.
But going from CDMA to GSM most phones work due most of the hardware and software is already built in the phone.

I can confirm this. Yes, your unlocked T-mobile S7/Edge will work with Verizon network if you flash the U firmware. I'm currently using my unlocked T-mobile S7 Edge with the U-firmware on the Verizon network. Voice, text, data work fine. No issues for me.

You can flash the stock Tmobile ROM or the U firmware. The only reason I got a new S7 when I jumped from big red was I had a huge scratch on my screen. I was running the U firmware when I went into tmobile and used the girls sim card from her phone to prove I could do it...

Don't know but I am on T-Mobile and I use alot from Verizon thread no issues so far

OK, so I have a question. I'm also trying to move from t-mobile to Verizon but I'm trying to keep my same phone. My phone is already paid off and i currently running t-mobile's SM-G935U over SM-G935T. But a couple of days ago i asked a friend to let me barrow his verizon sim card to test it out. But received a message saying "Invalid sim Card" "network locked SIM card inserted." Did i messed up something during the installation of the SM-G935U?

You need to UNLOCK your phone. It might be a Tmobile phone and running G935U software...but the sim is still locked to T-Mobile. Here is Tmobile unlock page information. you can request unlock in the T-mobile app or by calling T-Mobile....then it should see the Verizon sim and load up just fine once the phone itself is not locked to T-Mobile only sims. https://support.t-mobile.com/docs/DOC-1588
And for anyone else looking at this forum, There is no physical difference in hardware from a SM-G935T phone and a SM-G935U phone. Samsung actually made the hardware the same for all US Variants it is just the software that is different. And not that you would want too but you could load other carriers software on your phone if you wanted too(IE- running Verizon software on a SM-G935T, or ATT or SM-G935U (Stock Samsung Software) The only problem Running SM-G935U is they haven't upgraded the unlocked us phones to 7.0 yet. Where T-Mobile and other carriers already have nougat out.
The SM-G935U software however has all the US and even some Chinese LTE bandwidths enabled, and it also enabled the CDMA bandwidths to be used on the SM-G935 phones...hence why it will work with Verizon, Sprint, and even US Cellular if you can get them to put it on the account.*(I haven't dealt with US Cellular in years and with the new laws on moving phones from carrier to carrier in the US they might not have any issue with Bring your own phone to US Cellular anymore I do not know!)

Had you flash any ROM before via Odin?. If so, you will only need to download the verizon firmware (sammobile.com) and flash those files. if not > Open odin (Attached) load all the files accordingly (AP, BL, CP, CSC) in ODIN> put your phone download mode ( pressing fingerprint button + volume down + power) > connect phone to PC > Once all files are ready in ODIN hit start. You will get the success message and phone will boot.

Exit completely ODIN (make sure you run it as administrator), repeat the process and make sure all files are uploaded (AP takes a long time to upload) make sure to use the CSC file label as HOME_CSC. Try to flash again.

Does the phone have to be unlocked before adding these files or does it matter?

If you are going to use a verizon sim, you will need to have it unlocked. Firmware flash won't sim unlock/lock the phone.

Thanks for the quick reply. I thought I was gonna be waiting months. I got it tho. The home csc file wasn't working so I used the other one that reset the phone to stock. It was g935u firmware for tracfone from T-Mobile if that helps anyone in the future.

Great it worked.

I flashed the tracfone rom and everything is working well. I got a software update notification. Should ignore it or is it ok to update?

Bumping the thread...sorry guys. I just jumped ship from Verizon and went to Tmobile today with my S7 Edge along with my wifes S7 Edge. Can I flash her phone with the U firm from TMobile and is the U firmware from tmobile the same U firm that is provided to Verizon? Jist wondering. I've used Odin plenty and understand flash process.

Odin "Nand Erase All"

If i will nand erase all on my Galaxy S8(SM-G950F), will it delete the download mode?
If i'll do that, can i still just after that install the stock firmware?
Will it delete things that even stock firmware cannot fix?
BTW the phone is OEM Unlocked.

I did use Nand erase all on my s8 and it did not delete the download mode. What problem do you have?

Network is not available
No signal on my phone, did factory reset, twrp advanced wipe everything, reinstalling the stock firmware from smart switch, changed csc and changed back, didnt work.
Check tutorials to fix, from a tutorial:"In the dialer, type- *#197328640# or *#*#197328640#*#*", cant even type that, it will still show me Network is not available.
My IEMI is good, when i type *06# it is working.
Tried my sim card on another phone, it works, on my phone it should show signal even without sim.
Do you know how to fix this?

How does Nand erease work? So odin first erases the nand area, then writes firmware? After that what would happen to IMEI #, won't it erase efs folder?
The issue I have is with Galaxy S8 Active. I bought it a second hand and it was attached to Sprint. That person flashed it and possibly changed CSC to XAA in the phone, but flashing doesn't affect it at all. I have tried flashing T-Mobile or Sprint firmware, but the about phone page still shows XAA/XAA/SPR. There is no unlocked version firmware for this phone and it seems that only 3 carriers had this device (ATT, TMB and SPR) Whe I flash firmware, the progress goes fine and it passes, but all it does is change the build # of the OS.
So I wanted to do nand erase to remove all changes that original owner did, but don't want to destroy the phone.

Replying to a year old thread :|
I've nand erased before a long time ago, it didn't destroyed my phone but I do not remember if it will change the CSC to the firmwares one(Assuming that you use a firmware with the CSC you want).

Actually I do want to become TMB and I did flash the correct firmware for T-Mobile. I think original owner used something such as "Eng boot or factory binary" to go into service menu and change CSC to XAA. There is another interesting thing. When I go to about page, under Service Provider SW it shows G950U, but the rest of the phone is G892U. < I can't get rid of this!
1) Is there a way for me to maybe get Factory binary file which will allow me to change CSC? I did fine combination file, but it was for v2 bootloader, mine is v3 at the moment.
OR
2) Nand erase will do something good and erase the flash memory, unless nand option doesn't erase a specific memory location in the phone responsible for CSC.
Also, how can flashing a phone not do much in terms of really changing something in the firmware? I have not seent this before. I even tried flashing USERDATA file, thinking I would get T-Mobile's bloatware, but it didn't, not even TMB boot logo.

How to Full carrier unlock Verizon S8+ with Stock SM-g955u1 bloat free

DISCLAMER: I AM NOT A DEVOLPER AND MAY NOT BE ABLE TO HELP YOU ON YOU DEVICE. UNSUCCESSFUL ATTEMPTS TO FLASH FIRMWARE ON THIS DEVICE CAN AND WILL BRICK YOUR PHONE. BACK UP EVERYTHING IN EVRY CONCIEVABLE WAY.
After days of trying to do this with all the outdated guides and miscommunications and edits in post i decided to try and make a streamlined guide to help others.
NOTE: If your are looking for anything else other than a stock bloat free unlocked firmware then look elsewhere.
Also if you are using rev 1 booloader then this will ireversablly upgrade you to rev 2 bootloader not a real problem just a note
Download 3B's patched Odin 3.13 https://drive.google.com/file/d/17wH1YHcGsOCxbDGYDoy9VlnqO_Xi6IOm/view?usp=drivesdk
Download samfirm.exe
https://drive.google.com/file/d/1XdboeTqk8pSZyJQVt-IHVHFfznJ9eOQk/view?usp=drivesdk
Thanks to @zxz0O0
If you can't find your own drivers don't do this
1. Extract B3 Odin
2. Extract and run samfirm.exe
3. Make sure auto is checked use SM-G955u1 as model number and XAA as country code then search. It should find you the absolute latest firmware
Hit download and choose file destination. This can take a while.
4. extract firmware.zip
5. Run 3B's Odin and add file to there respective locations. I.e. Ap file in Ap slot etc. Use the non home CDC
6. The only thing you need ticked in Odin are already set by default
7. Boot phone into download mode power+bixby+volume down while the device is off
8. Read the screen that pops up very carefully and decide to continue at you own risk by pressing volume up
9. Connect phone via USB 2.0 port do not use a USB 3.0 port it will not work
Make sure Odin recognizes device if it doesn't then u have a driver issue
10. Press start and wait patiently
11. Phone will reboot it self setup device and insert sim card. You will probably get a notification say phone not allowed a quick call to the service provider you trying to use is all that's in order here
12. Enjoy your carrier unlocked stock SM-G955u1 on your preferred network
I AM NOT RESPOSIBLE FOR ANYTHING YOU DO TO YOUR OWN DEVICE YOU WERE WARNED.

So this gets rid of all bloatware?
From my knowledge, Verizon does not, and has not ever carrier locked their phones. Seems like a lot of trouble just to debloat.. Am I missing something here?

Any idea why it stucks at "SetupConnection.."

This worked GREAT! My Verizon S8+was working fine on AT&T before I did this, but I was stuck on Android 7.0. So thank you so much for this. There's only one thing that bothers me is in my drop down menu there's a notification that says "Sprint OMADM Checking Device Status." Which really isn't a big deal, it's just annoying. Another thing I worry about is, i'm using it on a GSM network, is it actively searching for a CDMA network at the same time and draining my battery? Any input would be appreciated, and thank you again!

The method will be similar just need the proper firmwares for your device

This being quite an old post I was wondering ...
I am currently on G950USQS5CSB1 with CSC XAS/XAA/VZW.
Currently I have no carrier bloat (good), I am on Mint with no issues (good) and I get prompt OTA's I assume for carrier VZW but I lack wifi calling which I would like (bad).
I have downloaded G950U1UES5CSB2 for G950U1
Will this work using the 3B modded Odin as described without having to flash the combination files?
normal and Prince Comsy Odin both failed.
Thanks
edit: Took the dive .... worked great thanks, now on G950U1 and have wifi calling and VoLTE

This is great, minus one thing, it installed facebook on my phone, which I didn't have before and never wanted and it won't let me uninstall it..

I'm hoping you are still monitoring this old thread. I have a Verizon Galaxy S8 and followed your instructions exactly (except that I downloaded the files for SM-G950U1 (my current model is SM-G950U). When I start Odin, it gets stuck at "SetupConnection" and never goes any further. Thoughts?

Yea. I just switched to Verizon. You should be able to just pop your sim in and it automatically carrier switch. Most of these are multi carrier

Yea not yet. I'm also on 7. We need edl files first. I got the combination rom for the boot img but edl is still missing. I got a few guys looking for it. I typed in the error you gave me and saw a few sites with no box fixes. Normally if you can get to the menu I don't see root being needed. But I may ne wrong since I've never seen this error

This would be great if it worked. However I have my doubts. You would first need to have the phone be from Verizon or be on another carrier and *unlocked* first before changing any CSC using the US OPEN firmware which allows you to simply put a sim card in and switch carriers by swapping sims and letting Samsung reconfigure the phone. The BEST setup is a SPRINT phone.. unlocked.. then converting to U / U1 firmware. You then have every possibility when it comes to carriers sitting at your finger tips!
Good Luck

Your post dont even make sense. The Verizon s8 at the time came sim unlocked. All you had to do was swap the csc. But worked unlocked out of the box. Why would a sprint device be the best setup. All the us s8s are identical. Sounds like you come from LG which is true on devices and versatility. Not Samsung.

Flashing a differenct CSC rom and keeping data

Currently on Snapdragon latest official Oreo with XAS (unbranded Sprint)
My phone was an originally Verizon branded, it now has XAS U1 firmware (model shows as U1 in settings)
I want to flash either U1 or U of ROM with csc of SPR. The reason I want to do this is because I want to fix/enable Calling Plus/Wi-fi settings.
I really do not care if my csc says XPR or SPR afterwards, I'm just thinking that flashing a rom designated as SPR might fix my Calling Plus/Wi-fi issues.
Is it possible when using Odin to flash, to use Home CSC and not wipe data.? I still feel with unrooted phone backup and restore still requires a lot of manual setup and I hate constantly doing this every time I flash.
Note: I've already tried to get wifi calling working using both Nova activities and in the phone settings without success , have been following the other thread about enabling Calling Plus on unbranded rom

After throwing in a T-Mobile sim and then going back to Sprint sim, I was converted to SPR csc. Sprint always seems to do this. So now I don't need to change CSC b ut I still am struggling to get wifi calling
The firmware for SPR and XAS appear to be identical so I am wondering if I should try to flash the U version of the rom . And of course attempting to keep data

Flashing over Sprint firmware for Spectrum?

Hey team,
I have an SM-A205U that apparently was flashed for Sprint or Boost. I put a Spectrum (MVNO) sim in the phone and it works, but I can't get rid of the Sprint device registration failure notification. I think I saw during bootloader that it lists BST as provider.
I haven't been able to figure out how to get rid of that Sprint branding. It also shows up in "About Phone".
Which firmware do I need to load to get rid of it? I looked at sammobile, but don't know which one I need to download to have a brand-free firmware.
Any thoughts?
