I'm in the same boat. I'm trying to get wifi calling as well. Lets hope someone helps us out here....

Looks like stock firmware for now. If I flashed an att phone to unlocked, is it as simple as flashing back to stock?

I flashed att from unlocked and all att features working perfect. Just get bk disabler for the bloat and its the same as unlocked one but better designed for att

He was not too clear about what he wants..
He wants VoLTE on an Indian carrier Jio.

have you try this rom http://forum.xda-developers.com/att-lg-g3/development/rom-d855-stock-rom-d850-t3083359 dont know if it will make any difference

if you have APH1 you can now flash API3 to have unlocked g935u

So i had taken the update for my verizon g935v which updated to APH1 which disabled you from going to the 935u... well 935u received a new update. API3 is now installed on my phone. Heres the screenshot. check it out!

Thanks I was just going to post and confirm this. I'm on PI3 from PH1 as well. I'm uploading PI3 now and will post the link here when it's done.

No, if you don't want to root, you can have stock u firmware without root, but you're not going to have WiFi calling or volte without root, at least you had to have root before haven't checked on the new firmware.

If we update from PH1 without root can we go to PH3 and follow the root process

On sammobile there is a USA version and also a USA (Verizon) version. Is there any difference in the files?

What else is broken on this Firmware for Verizon? I don't care about Wifi Calling or VoLTE.
Vvm I think that's it.

OK, do you have to root the FW to be able to use it?
I get the dm-verity issue when I flash this on my ph1 device
Sent from my Nexus 6 using Tapatalk
Here if you want to root here is a new root bat with latest supersu image just extract zip enable adb on phone plug in phone run the root.bat
S7Root.zip
Then to fix volte and VV mail and wifi calling flash this in flashfire

I dont think this is a U firmware issue, I had this issue on rooted PH1 too.
Hi, when you say unlocked, you mean SIM unlocked?
As far as I know VerzonĀ“s s7 edge comes factory sim unlocked or do I have to flash this firm to hav it sim unlocked?

SM-G930U Now Flashes to SM-G930T

With the latest update of PI3 on the SM-G930U the bootloader is now on version 4. Found out trying too flash a version 2 bootloader from Verizon firmware.
What this means? Users on the SM-G930T that wanted a bloat free smooth firmware can enjoy just that now by downloading and flashing the latest PI3 firmware on sammobile or samfirm tool.
Damn ! That's some good news after so long !

Perfect.. hope you are enjoying the ROM.
Can you root this firmware?
Edit: Root is possible.
Be careful if you want to go from 930T to 930U and then back to 930T...I had to use Smart Switch because I was getting an error when flashing AP with ODIN...

Just a note, you'll lose FM radio support. I was really hoping they would include it in the update, but no love sadly. I have the U and am considering flashing the T for it. Comes in handy at the gym for watching tv, but then I'll have bloat. Decisions decisions.
Can I flash the tmobile modem over this and get the 4x4 mimo support? Or does that also include some code in the firmware?

No issues on my end. I flashed T then back to U without any hassle. Probably is your odin or faulty usb cable or port.

On another thread someone said to flash the tmobile radio from the latest build to get TMB specific features. You can try at your own risk and report back.

Great, thanks for the input. Am sure a lot will find this handy.
A somewhat silly question but does flashing the U firmware automatically unlock the SIM? Or is it still SIM locked?

No, flashing the U firmware does not Sim Unlock the device. You must first unlock then flash if you want to switch carriers. Otherwise just flash and use your same provider SIM.

Flashing this image means it will come with Verizon bloat?
This doesn't bode well for the few of us stuck with sprints updated bootloader waiting and hoping that this update would cone with the updated bootloader so we could finally switch firmware I'm guessing

actually haven't crossed any information indicating that, although I was more wanting to get off the Sprint firmware but stuck on the bootloader 5 firmware of Sprint's been waiting months in hope the oreo update for verizon would contain the #5 bootloader version so i could finnally come off the Sprint's firmware as i am a verizon customer.

Works well! Thanks again!!! Any chance you would be making a hybrid rom for this that is as clean as the unlocked and has all the features but also has Verizon features such as video and wifi calling?

It's not a rom. It's Verizon stock firmware so Verizon bands and Verizon carrier specific things only work.

T-Mobile variant clarification

After reading a few threads, it would seem that there is an msmtool for the tmobile variant now but still no method for root? I'm not counting the method to convert to international version.
Do I have this all correct or am I missing something?

The T-Mobile MSM tool is to revert back to the T-Mobile firmware. If you use the MSM tool to convert from the T-Mobile version to the international version, you can root but you must be SIM unlocked prior to converting to the international version.

Right I had mentioned that in my post, but I'm a little apprehensive to try it because I don't want to have issues with lte or wifi calling.
Is there no way to just root on my stock rom? I kinda just want a custom kernel and themes.

There are no issues what do ever with LTE of Wi-Fi Calling. They work great. The newest update for the Global/International version fixed the issue some had with Wi-Fi calling not switching over fast enough.
No, there is no way to root the stock T-Mobile rom.

Yes there is. Simply unlock bootloader and patch the boot image. And flash it in fastboot.
