My official sgh-m919v thread about rooting and backup.

I'm Just sharing with people that got this phone and doesn't know where to look for useful information's.
This model look's like a variant of the T-mobile model SGH-M919V
I was able to root my model SGH-M919V by following this link: http://forum.xda-developers.com/showthread.php?t=2258633. All credit goes to them. Not to me.
i also installed Goomanager http://forum.xda-developers.com/showthread.php?t=2263001. All credit goes to them. Not to me.
I did a backup of everything with the TWRP. I will link the backup here.
this backup gave me an archive of 2.47*Go (2,655,360,375 octets) uncompressed.
Doing *#1234# give me this result.

I don't understand why this thread is in the AT&T forum, but anyway as to your question, go to either http://www.sammobile.com/firmwares/ (you have to register to download) and enter SGH-M919 in the search box or go to http://samsung-updates.com/device/?id=SGH-M919 and download the firmware for your phone. This is version M919UVUAMDL which should be the pre-ota version. Flash with Odin.

I'm not quite sure what you mean. Not the same number as what? I understood @ferlogan wanted to downgrade to original firmware so he can use the motochopper root method.
The firmware I linked is taken right off of the Samsung Kies servers, and since the phones are so new, it will be the original firmware that is on the phone when the phone comes out of the box. I don't have your phone, or carrier, as I'm still on SGH-I777 and AT&T. But you should be able to verify in the T-Mo forum that the version number is the same as the original firmware. The version number for the ota update will be slightly different.

I think he mean to say that the number you put is for SGH M919 (T-mobile version) and we are on canadian Videotron or wind which is SGH-M919V and doing *#1234# give a different version M919VV....
I am also in same boat I want to know which firmware to downlaod to downgrade in order to Root my videotron canadian version, I don't want to brick my phone.

So you can't even get the phone into download mode now?
Its volume down + power + home. Then plug it into the pc and run Odin. If it shows up on one of the COMs then you're good to go.

yeah i was able to bring it back to original state with the official rom and it even show offical rom in the odin menu now. the only problem i got now is, when i connect kit to wireless network, my speedtest is around .3Mbps and .34 for the upload.
The rom i used is the one available in sammobile and it not exactly the same number as before. Even with Skies it upgraded to this version and it so slow on my network now.

how did you brick it?
I too have a SGH-M919V, mine is with Wind Mobile and I just recently got it.
I am assuming there are no stable or compatible roms with this model yet? I want to try rooting it how you did it and then I suppose wait for a stable rom. I'm anxious that our model isn't on sammobile.. yet.
Just curious, is yours also with Wind Mobile? my AP, CP, and CSC came up with the same numbers.
I wish there was more information and light on this particular model, thank you for having this thread.

Some of the other users and I have another thread going that has some of the information that you are looking for. Our phone does have stock odin flashable firmware and it is on sammobile / samfirmware now.

Hmm not sure about the theme store but you don't need to use an international rom. You can use a Sprint rom. Although all Note 5's are essentially the same (there might be some variants with differences), the kernel might be different for each. I would stick with the Sprint rom. Maybe try some of the roms posted in the development section to see if the theme store would work on those roms.

nope. i have flashed "sprint" custom rom!

Thing about sprint is...it has its own network. So unlocking it is not the same as tmobile and other networks. Example 1, sprint unlocked only works on sprinit network and other networks by sprint. Example 2, any other company, tmobile, verizion, unlocked can work with a different sim card, internationally. If you put a different sim card in the sprint phone it wont work for some reason, but any nonesprint phone it does if unlocked

This is not true. The N920P can be unlocked and used on domestic GSM carriers. I'm currently using the N920P on straight talk (ATT) with LTE on stock/rooted rom.

Hey insane howd you get 4g? On att?and are there any good roms for sprint note 5 with att

How you did it?

I used idoneapps for the unlock (works great, kudos to those guys) .You will have to make NV changes for LTE (directions are on this site). You also need two APN's (one with LTE as bearer). Network Mode needs to be GSM/WCDMA/LTE. Handcent with manual APN for MMS keeps from having to reboot nearly everytime you receive an MMS as well.
---------- Post added at 09:01 AM ---------- Previous post was at 08:44 AM ----------
NV edits can be found http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455 . You do not need the storage patch for this device, obviously.

Need assistance on upgrading to Nougat

Hey Team,
I have a S7 that is unlocked but originally from CWW (Jamaica). I have yet to receive the Nougat update. I am using the phone on Virgin Mobile and I am in Canada. How do I go about getting the Nougat update? I tried Manual update from settings, no luck. Tried Smart Switch and no luck..
Change the CSC? If so can someone please provide me a walk through in doing so.
Update: I followed these intructions and was successful in flashing that firmware.

Wifi Calling with Unlocked Note 10+ (AT&T)

I'm not sure if this is supported, I can't seem to get much help from AT&T, but I purchased an unlocked Note 10+ from Samsung. I do not have WiFi Calling which is a crucial feature since my office has terrible reception and I use the phone for work.
Is this something I should be able to get working with help from my carrier or is this ROM/build specific? Any help would be appreciated, thanks!

Along with one or two pros, I found this to be one of the cons in using an unlocked phone with Verizon a couple of years ago, along with no notifications. I spent countless hours over several days on the phone with Samsung and Verizon before finding out this was a known (by Samsung) issue. I returned mine and got the Verizon branded one. Things may have changed since then, but it cured me of the unlocked version, especially since contracts have fallen by the wayside. If they can't resolve the WiFi calling, Samsung should allow you to return it. I hope someone else has a solution for you.

I Tried flashing the AT&T firmware N975U1UEU1ASH4 from Sammobile and sill no wifi calling.

I am in the same boat. Just out of curiosity what does the service provider SW ver. look like? Mine shows ATT/ATT/XAA
Still no wifi calling or carrier specific options...it's kind of strange that these phones provision the features when you put a sim card in.
I called both At&t and Samsung who were equally less than helpful.
I am looking back to some of the S8+ forums about CSC swapping because I feel like that might be a starting place...

You downloaded N975U1 unlocked rom, it was still rom for unlocked note 10 not AT&T or variant note 10. If you want full AT&T features like wifi calling, video calling..you should download and odin this firmware N975USQU1ASH4 which is AT&T Variant N975U. I am still on unlocked Galaxy note 9 N960U1 and I odin Verizon note 9 SM-N960U on my unlocked Galaxy note 9. The ROM works with every carrier anyway.

Okay , I got my WIFI calling . This is the correct one to download and flash......... DO NOT Download the one that says AT&T it's going to just flash the same N975U1. Good luck:good:

What about for the regular Note 10? Is it N970USQU1ASH4 for the unlocked AT&T version?

I flashed N970USQU1ASH4_N970UOYN1ASH4_USC from sammobile.com

Hmm I did the same thing. I flashed both the att and usc firmwares. Odin said pass but I didn't see any difference. I used the home_csc file though. I didn't want to wipe my phone before knowing whether I used the right firmware.

I have an N970u1 but flashed it to the u version. Is that what you did?

Well my model number still says U1. So does that mean that me flashing both the USC and ATT firmwares did nothing?

---------- Post added at 08:48 PM ---------- Previous post was at 08:27 PM ----------
Reading another thread, did you first boot up with an att sim card before flashing? I believe you have to do that first.

Ota updates
Will the OTA updates work after flashing the att stuff? I know theres a new firmware but the phone is saying it's up to date.

I'm having a problem with this too. I flashed the USC version and got the ATT Bloat, but when I try to enable wifi calling I get "Oops! Wi-Fi Calling can't be turned on right now. Please call 611 or 800-901-9878 for assistance. (APP0008) Can anyone help?
Is it possible they are locking Wifi calling based on IEMI?

Reflash AT&T 20 Ultra to Unlocked Firmware?

I've looked through threads of people doing the reverse of this. It's been a few years since I've had an android and was running nexus devices then. What's the process to flash an unlocked firmware on an AT&T locked 968U to the 968U1 firmware (assuming there aren't issues doing it)?
Are there any other pitfalls I need to be aware of prior to doing it other than the wifi calling?
If this is already posted somewhere else, please feel free to point me there. I didn't see any info about going from a carrier locked 968U to unlocked firmware.
Thanks in advance.

I've looked through threads of people doing the reverse of this. It's been a few years since I've had an android and was running nexus devices then. What's the process to flash an unlocked firmware on an AT&T locked 968U to the 968U1 firmware (assuming there aren't issues doing it)?
Are there any other pitfalls I need to be aware of prior to doing it other than the wifi calling?
If this is already posted somewhere else, please feel free to point me there. I didn't see any info about going from a carrier locked 968U to unlocked firmware.
Thanks in advance.

I just did this today went from TMB locked one to unlocked (For a family member) mine is unlocked. All went well no problems at all. Just download the U1 Firmware you want to flash and for CSC use home_csc (In ODin) so you can keep your data and probably the wifi calling feature too ( i did that all features are intact). Use the Odin and firmware from Ota and non Ota thread . Enjoy

What did you gain that made it worth it for you? Also, I'm on a Locked ATT/Firstnet Ultra and am wondering if flashing to an Unlocked Firmware would give me more control of my device.

If your on FirstNet I recommend that you stay on ATT branded software, I'm not sure if band 14 will work properly for you if you are on unlocked software. Thank you for your service!

You can get VoLTE back, but yeah, WiFi calling is not gonna happen.

The thread is for T-Mobile, but most of it works with AT&T devices as well.

I flashed the U1 firmware (ATJ3) onto my AT&T Note Ultra, then flashed the Home CSC from the AT&T U firmware. I have VoLTE and WiFi calling.

Help!
Hello all, I have a Note 20 Ultra 5g that is unlocked and I'm looking to flash the original ATT firmware for this device.
Having this unlocked version on Firstnet has been nothing but problems and I don't have access to band 14 or wifi calling.
I see this thread is a little old but if anyone could help me out or send me in the right direction I would greatly appreciate it!
I have rooted some of my older phones several several years ago so I think I could pick this back up pretty quickly. I know over the years things seem to get easier and have probably changed quite a bit since I've last done something like this.
Thanks in advance!

My comment was made before we were able to change IMS settings directly.
You can get it all now. VoLTE, WiFI Calling, RCS, Video calling...

AT&T hasn't released any "official" firmware for the Note 20 series.
Since Samsung firmware is multi CSC, just flash any firmware with the same build number as the AT&T variant and use your AT&T SIM card.
Go to this thread https://forum.xda-developers.com/t/ota-and-non-ota-firmware-for-n986u-and-n986u1.4143833/
Make sure you know what device you have, U or U1. Then grab the appropriate version.
Fir AT&T U devices, N986USQU2DUCA or N986USQU2DUCA will work.
For AT&T U1 devices, N986U1UEU2DUCB is the most recent version.
