[ODIN] Stock Nougat Firmware [SM-G935T] S7 Edge to use it on 935v

Here is the link to the tmobile original thread
[ODIN] Stock Nougat Firmware [SM-G935T] S7 Edge
Instuctions provided by jrkruse (original post)
1. You need to be on Verizon Beta Nougat 2
2. In developer options turn on OEM unlock
3. Reboot to download mode
4. Load the files you downloaded in the corresponding slots in odin BL,AP CP, CSC the files are labeled this way
you dont use the G935TUVU4BQB1_Boot_Recovery_Image.tar.md5 until later
5. Install with odin the phone will reboot to recovery to finish the csc install
6. If the csc install in recovery fails reboot to bootloader in stock recovery
7. In odin reflash the CSC file in the CSC slot in odin. The phone will reboot to recovery again and install the csc files
8. Once the phone is done installing and wiping in recovery try and catch the phone as it reboots and reboot back to
download mode (PWR+Home+Vol Down )
9. Use odin Install G935TUVU4BQB1_Boot_Recovery_Image.tar.md5 in the AP slot
10. Let phone reboot and go through setup
11. During Setup you may have trouble typing info in the setup boxes the keyboard has some bugs in setup. I recommend skipping
adding any accounts and do it after your through setup. Or use the alternative method to find your google account
12. Once through setup download 4G LTE Switch and use to Change Network to LTE/CDMA auto (PRL)
13. I recommend downloading Package Disabler Pro (It Works now) and disable all Tmobile Apps
I found samsung pay wasnt working I found that the tmb bootloaders and persist.img needed to also be flashed I made a new odin flashable package and install instructions. All seems to work now except of course volte and wifi calling.
Explanation why you need to be on nougat beta 2
Download:
TMOBILE_NOUGAT_VZW.ZIP
ODIN v3.12.3.zip
Possible Issues and solutions :
Q: after flashing the bootloaders and persist.img, it broke all data and calls and texts again.
A: they need to be all flashed at same time. Maybe Wipe data and it might work
Q: The Google "email or phone" text input box still only accepts one letter and any extra letters overwrite the previous letter typed.
A: The samsung keyboard will work fine if you just goto settings on the keyboard to language and types and change to US english.
Q: So the question is..... this worth flashing or wait for vzw?
A: Other than no volte this definitely the best running Rom so far. It is much better than beta
Q: 13. I recommend downloading Package Disabler Pro (It Works now) and disable all Tmobile Apps
Care to share your list?
A: List of Tmo apps to disable
Q: Except MMS isn't working, for me anyways. VoLTE isn`t working.
A: I got volte working and video calling maybe this will help mms for you
Download App shortcut maker from playstore
Select all activities find IMS Settings and create shortcut
Open the ims settings from the created shortcut
Choose Ims service switch
Click on MMTEL switch
Click on RCS switch
Under MMTEL section I enabled all the options
Q: Cant get this thing to flash CSC...just keep getting the dm-verity error 0x02.
A: 1:Flash all 4 files in zip.
2:let reboot and see if you get dm verity error.
3:if you get the error than reboot to bootloader and reflash all 4 again.
4:after it reboots again it will say error.
5:reboot to bootloader and flash the csc again.
Q: in 4g lte switch, i dont see the option for lte/cdma auto. could this stuff be because csc didnt flash correctly?
A: if you have the verizon data icons you know the 4g lte then it flashed correctly. If you see data icons that ate not verizon then it didnt flash correctly.
When every one is starting over are you flashing a pit file when going pack to ph1. If not you need too.
P.S. All credits goes to jrkruze. :good:

You mentioned to install Nougat beta first before installing t mobile firmware. Is that necessary? Also, any link for Verizon apn?

Look at you apn settings and just copy it. I didn't mention about to install nougat beta, I mentioned that it was installed successfully on nougat beta and that you must be on latest bootloader.

Okay so I have T-Mobile Nougat installed on my device, and I've changed my VPN over to VZWINTERNET, and I can't seem to get anything working (calls or data).
I'll continue to toy around with things though.

The T-Mo one you posted. Odin with ap,bl,cp and csc selected.

After toying with tons of things on the Tmo firmware, I tried booting into Odin, and flashing the Verizon pi3 CSC. That gave me a bootloop. I then tried reflashing the entire Tmo Nougat with Odin, but replacing the CSC again with Verizons, same bootloop. So now my phone is being flashed back to the trusty U MM.
I can only assume now that running the Tmo firmware on VZW will require root to make CSC edits. But Verizon will release our own Nougat before we get root.
Now I guess it's just a race between Verizon releasing 7.0, and the G935U getting it.
$50 on Verizon.
Edit: After flashing the G935U firmware again, after the first boot I was greeted with a message saying "your device must update to use new features from your SIM card." And I booted to a weird all blue screen with a big SIM card on it. I've never seen anything like that. I'm not sure if the Tmo firmware messed with stuff, so I'm going to fully flash the G935V firmware, THEN reflash the G935U firmware, just in case the G935T firmware messed something up.

they also did something to disable all package disabler apps even if you go back to MM they dont work. They screwed us goood on this

so @spiderkr were you able to get it working or just going off of other reports?

Beta 2 Verizon Nougat

Unable to select network
Under "Network Operators" I selected Verizon Wireless, waited 5 minutes, and now got Unable to select network. Then, maybe a minute or so later, it says "Unable to connect. Try again later." Is there a way around this?

Sprint S8 Active flash to T-Mobile?

So i've read that the sprint version of the S8 Active is on bootloader v5 and the T-Mobile version is bootloader v1. Is it then possible to flash the T-Mobile firmware onto the Sprint Variant ?. The device is already unlocked but i would like Wifi-calling to work for T-Mobile.
Edit 1: Found this and successfully fully flashed from Sprint to T-Mobile(everything works including Wifi Calling). Only works if you are on bootloader version 1.
https://www.youtube.com/watch?v=DEDDTcR1SiQ
I AM NOT THE CREATOR NOR DO I TAKE CREDIT FOR THIS

No apparently the bootloader version must match or be lower so in this case sprint is higher so you can't flash. I've tried and downloaded the tmobile oreo firmware; you'll just get a fail in odin

That is the part i am maybe not understanding. My Sprint S8 active says it is Software version G892USQS1ARC1. Doesn't that mean it is bootloader version 1?

Sorry I was wrong! I actually flashed it! Very happy right now. I was being stupid and using an older version of odin before. Now I successfully flashed sprint to t-mobile oreo with no problems! Use Odin 3.13.1; not prince comsy mod or anything else. So it was bootloader 1 after all; there were some misleading posts without proof. I will trust the software number from now on

ARE YOU SERIOUS?!?! Does wifi calling work for you now?

I'm not sure. How can I check? I'm on Fido which is Canadian carrier without WiFi calling. I'm guessing I'm supposed to be looking for a tmobile WiFi calling app. See attachment screenshot for proof. Still recognizes my phone is from sprint

Yeah i just finished flashing it and i get the same as you. Phone still recognized as Sprint and no WiFi calling. Darn. Android 8.0 Oreo is a huge plus however.

I think we need to follow this guide to change carrier but the thing is there is no factory binary for the s8 active so this guide won't work until there is one...
https://forum.xda-developers.com/galaxy-s8/how-to/switch-to-carrier-firmware-100-t3609487

Actually I have found and flashed a factory binary trying to change it to T-Mobile. The problem I ran into is they want you to download the firmware with "w" after the model number. That is what I think let's you change the option after typing in the code. That firmware is only for s8 I think(not active as it has the s8 model #). Without flashing that, after I typed in the code the only option I had to choose from was sprint. No "xac" or whatever it was.
If I am not mistaken. The model with the "w" is the Canadian version of the s8. The s8 active is US only I think.

So Im getting ready to pick up a Sprint version to use on Att or Tmobile (good deal). Are you guys seeing any issues after flashing? Thanks

The only thing I've notice is there is no option for mobile hotspot( i don't think it was there to begin with, i could be wrong however). Other than that it works perfectly. Great battery life and everything. Flash the userdata to get rid of the Sprint Boot animation if you'd like. I did it and now there is just the "Samsung s8 Active" logo, then lock screen. Goodluck.

WiFi calling works fine on T-Mobile without flashing to T-Mobile firmware. Only issue is that sometimes it gets stuck enabling WiFi calling requiring a reboot. Band 12 also works, its in the Sprint specifications. The big question I wonder about is if band 71 can be enabled.

flash not working?

Did you follow the video I posted?. Ignore all the other comments about things not working. When i updated the OP with the link, it fully flashed the sprint device to T-Mobile. The only thing you have to watch out for, is if your Sprint software is running a new bootloader. You can tell by looking at the baseband version number. This will only work if you are on bootloader 1. My baseband is currently "G892USQS1BRD5". The bootloader version is the 5th character starting from the right. The number 1 before "BRD5".

SM-G930P to SM-G930U

I have the SM-G930UP baseband version G930PVPS4BQE1
I am preparing to flash the universal firmware, but with the T-Mobile modem. The goal is a phone with the U firmware and the T-Mobile modem.

In some of the reading I have done it appears advantageous to have the carrier modem of the service provider you use; I'm assuming because the carriers tweak the modem for use with their particular infrastructure.
I don't know if that's true, but I have seen a number of posts to that effect. It sounds logical and I figure it can't hurt as long as it works.

I doubt it.
I've been using U-version (converted from SM-G930P) on T-mobile for a year and found no issues whatsoever.
I was reading the opposite, something like U-version has more LTE bands unlocked (which makes sense as it should work with all carriers)
Also someone here claimed it has extra bands for Europe. like band 7, 20

Interesting. That seems logical too.
Unfortunately I may not be flashing anything as every time I have downloaded firmware from SAMOBILE and extracted it I have got an error message that the AP portion has a problem. If I "retry" it gives me the same error. If I "skip" it unpacks everything except the AP file. I have tried several times with multiple downloads. Each one took the full two hours to download, so it's been a lengthy process with no results.
When you flashed the G930U which variant did you use?

I flashed version G930UUEU4APL2 with odin 3.12.3
It was back in January 2017. Note the number 4 in the version. This indicates bootloader version.
I believe you can no longer flash this version if your current version has 5 (or any greater number) in place of 4 because you're not allowed to downgrade the bootloader version.
Sprint is known to bump the bootloader version from 4 to 5 for (supposedly) blocking this type of conversions of their branded phones.

Sprint is currently on bootloader 6, actually. Crappy obstructionist commercialism specifically to block people converting.
I have been denying and rejecting the software updates since May of 2017 which is when I got that software version, so your G930UUEU4APL2 firmware from January would not work on this phone as my Sprint firmware is more recent.
I should be able to flash the most recent version of G930U, however. I just can't seem to download one that will extract the AP portion. It's really frustrating.

For newer firmwares you may need to use the latest Odin version (3.13.x)

I wonder why did you choose XAS version.
I also remember back in time I downloaded two versions of U-firmware (SPR and XAA) and compared the files they appeared identical.

This is what I was saying. The last Sprint update I did on the phone was May 2017. I have been dismissing the update nag since then. Which means I could flash any G930U firmware with a date later than May 2017 with the same bootloader number.
Sprint has been trying to block this: their bootloader number is currently on 6, all the other carriers are on 4.

Yep. The link I used to download the latest version was in the first post of this thread. 3.13 worked just fine.
The problems I was having had to do with the my computer, but I solved them and was able to to flash the latest version of G930U.
The phone is snappy and without the annoying lag.
Call quality improved immediately. With the Sprint firmware on the T-Mobile network there was a glitch with using the voicemail icon on the dial screen - it would fail to call the voicemail and give an incomplete call error; the workaround was to call myself from contacts and enter my pin to get to my voicemail. Now the voicemail icon on the dialer takes me to voicemail without a hitch. When calling it doesn't have a 15 - 20 second wait before ringing the number (the top left of the status bar would read "Attempting"). Internet reception is also better especially in the NYC subway.
Also as soon as my phone went from Sprint to T-Mobile I could no longer send or receive pictures via text. Apparently Sprint firmware wasn't interested in sending MMS messages anymore, but with the U firmware they work just fine and regular texts go through more quickly as well.
So far battery life is about the same as far as I can tell, maybe a marginal improvement. Nothing to call home about.
But mostly I seem to get the overall desired reception improvement: it stopped dropping calls, and the call quality is solid and the undersea world that had been happening with the Sprint firmware is gone.
Also the fingerprint scanner is working better.
It's much improved.
I REALLY like how it seemlessly goes from voice on network to voice on WiFi.
Question: will this get OTA updates? Is it fantasy to think the G930U will get Oreo?
I am interested in testing the various towers, most frequent LTE bands, signal strength, and handset radios. Is there a thread for that or any apps you know of?

Yes it will get OTA updates including Oreo. U-version lags behind branded versions in this regard though.

Hey guys so I am brand-new to all this but need to convert my g930p to g930u. I just want to clear this up: because my software version is Q930PVPU6CRE7, I won't be able to flash the version OP used but must find a version with a 6 in it?

I'm in the same boat with my wife's phone. Limited bands available meaning it's on 3G more often than not, and MMS won't work if connected to WiFi. Not to mention the sprint junkware... is there any way to change from G930P to a G930U firmware if the phone is currently on bootloader version 6? I don't mind rooting...

I flashed G930U on G930P but network still not working. It shows unknown network and Radio Off. Mobile can read SIM menu and Contacts but no signal. Any help please?
EDIT: Now I know that changing ROM or rooting does not network unlock.

S7 International Oreo CSC for T-Mobile

I've been searching for days now, yet can't find what I'm looking for. I have the S7 Edge International vatient SM-G935F and have recently upgraded it to Oreo on the Superman Rom. I'm loving my phone again, yet I have yet to find a solution to enable WIFi calling and VOLTE for the S7 International on TMB. Can anyone assist? I'm sure there are a ton of other folks in my situation, yet everything I've found only works on Nougat or is only for newer model phones.
I'd greatly appreciate any guidance to get this final piece of the puzzle solved.
Thanks in advance!

Flash Home_CSC for your carrier over top of the ROM, CSC is what controls your carrier specific features like VoWiFi and VoLTE
Edit: Although since you're using T-Mobile, isn't that US based? Make sure you only flash the firmware appropriate to your device. US model S7's use a different SoC so you can't flash it over an international phone

It's the international version that I'm using on a US carrier. There is no firmware from the carrier directly due to the difference in SoC on the phones that were sold in the US.
This being said I was able to use the CSC selection tool with Nougat, yet the tool hasn't been updated for the S7 running Oreo.
My hope is someone has created a compatible tool or flashable fix. I've found several for the s8, yet nothing for my S7.

You could do a full TWRP backup, try the Nougat CSC tool or the S8 one and see how it runs, and if any issues you can restore the backup or dirty flash the ROM

You can try this: https://forum.xda-developers.com/showpost.php?p=69864872&postcount=5484
using this: https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957
which is a recommended step when doing this: https://forum.xda-developers.com/galaxy-s7/development/rom-s7-rom-v1-0-t3356197
So, it might just work for you.

Also, I've not done this yet, but I am possibly about to install the Superman Oreo ROM too (I have the sm-g930f), and you mentioned you find only tools for Nougat. The second link I provided is the 2.5.0 CSC selection tool for MM or Nougat, and no version listed for Oreo, yet that CSC selection 2.5.0 version is linked to from the Superman Oreo developer in one of the steps, for flashing CSC after flashing the ROM......
So, my question to you is: have you tried that CSC selection tool for Nougat already just after flashing Superman Oreo, and it doesn't work? One of my main reasons for going with the Superman ROM is to have the proper CSC installed for my international (exynos) variant on US T-Mobile, and I'm not even gonna start if the CSC won't install.
Thx!

Yes, I've tried the Nougat 2.5.0 version as well as the s8 version, neither of which seem to work for my phone on Oreo.

You could do a full TWRP backup, try the Nougat CSC tool or the S8 one and see how it runs, and if any issues you can restore the backup or dirty flash the ROM

Tried both of the tools already (csc select 2.5.0 for Nougat and the Oreo version for the s8). S8 version says, nope, this is an S7 and won't install, the S7 version installs yet ends up in a boot loop. So, no dice as of yet.
I've asked for info from the dev on his forums with no response as of yet. Crossing my finger that he releases a new version or someone else can work some magic.

I just installed Superman Oreo last night then installed csc from the Nougat 2.5.0 csc selection tool immediately afterward. I got it all working, including volte. What boot loop issue did you have? How far did it boot and what did you see before the reboot?

After android booted the system said it was rebooting to complete the configuration for new SIM functionality. It then rebooted itself to TWRP. From TWRP I selected boot system and then it would start the same process over. I had no control while the message displayed. I also noted random crashes at the same time while Android was booted.
I cleared cache and tried again with no change. Really happy you got it working, can you detail your progress?
Thanks!

Ya, that's the same issue I had.
I just typed it up in another response on the Superman Rom for g930f thread:
https://forum.xda-developers.com/showpost.php?p=77640954&postcount=13063
basically, when at the point you were at, you could pull the sim card (you won't get the error when you have no sim in the device) and keep on going with the setup, until you have the device rooted (recommend magisk) and then connect to your device and disable the package that's giving you a problem, using the adb shell and "su; pm disable com.sec.android.AutoPreconfig"

I was able to get the phone to stop rebooting with the sim installed by disabling the preconfig service, yet I'm still left with weirdness. I am getting two crashes that appear to be associated with Samsung Messages (SMS program). Copy code and messages are continually crashing.
Also, I am able to see the wifi calling in the pulldown, yet it doesn't appear in the actual configuration menu. Things are still very wonky with the Nougat CSC.
Any ideas?

I was able to get past the sim card issue, yet then experienced several FCs from "Messages", "Floating text" and "Copy text".
I tried clearing cache, a dirty install of Superman, clearing messages data, no dice, same errors. Also, as mentioned the wifi calling still doesn't show up in the other network settings, although volte does show up and the icon for wifi calling shows in the pulldown config, yet I can't open details.
Note, I also saw a note from the developer of CSC Selection that said nougat CSCs had the potential to causes FCs, not sure where I saw it, yet probably on these forums or on his website.
I haven't tried a clean install yet, but that's my last option as it entails a day of work.
Still hoping someone has the answers.

Not really, except that my approach, when encountering issues like this, is often to start at the beginning and fully work through it again. When I had this issue, I was not satisfied to have let the system boot multiple times, so I actually shut down, uninstalled the sim, reformatted /data, fully wiped, installed SuperStock kernel with the ROM, did not ever let it install bootloader and modem (stayed with what samsung pushed with the initial Oreo update, ERG2), i DID let the aroma installer install the default btu csc, then when rom install completed, I installed the tzo csc, booted once to the spanish "Hola" screen, immediately rebooted to recovery, installed tmb csc, rebooted again, did the initial android wifi and google setup, rebooted, installed magisk, rebooted and adb shell disable that package, shut down, install sim, reboot and went to steps 7,8,9 from here https://forum.xda-developers.com/showpost.php?p=69864872&postcount=5484 I honestly have NO IDEA why that link had me install the brazilian csc right after rom install, boot then install the tmobile US csc... that seems weird, but I did it, and it worked (?) At any rate, since I had fought with it for a few hours prior to that, I kinda knew how I should properly sequence the setup for best chance at success, starting from the beginning. I have a g930f.... is yours a g935f? not sure that would make a difference, but if you have the same hardware, then you must be able to reproduce the successful results.
I should also add that wifi calling is not something that I've actually done... I haven't needed it yet. But I do have the selection in Connections > Mobile Networks > VoLTE calls, and I use LTE Discovery app to show me that my phone connects to LTE band 12 now. I also now have a working "Wi-Fi Calling" toggle in my toggles pulldown menu, and while it is on, I made a phone call while connected to my home wifi. I haven't yet figured out how to verify it's working. I suppose if I really want to test this, I could tin-foil the house so I can't get cell signal, then see if I can make a phone call while I'm on wifi!

What kernel did you install?
Yeah, I dug a little deeper, and I may not have wifi calling working, as it is not something that shows up in Settings, and if there is a toggle, I should be able to find it in settings. .... same as you, I have the wifi calling toggle, and VoLTE in settings, but not wifi calling in settings. weird that my toggle doesn't seem to have an issue turning on and off... I'll need to figure out how to test this.
No force closing though. It all seems quite stable, actually. But, yeah, it takes forever to setup all the apps..... about 50 of em!
Good luck!

Thanks for your diligence, I'll continue to hack away at it as well and perhaps we can put this to rest together. I did find one other CSC that does seem to work until it tries to register the WIFI calling. Perhaps this will help us. I'll attach it in the next message. (Need to post it from my phone).

Here's the TMO version that I was able to install without issues. I think it's Europian, yet it does show VoLTE and WIFI calling enabled. The issue is when it tries to register on the TMB servers (probably pointing to Germany). My hope with posting this is that someone with more skill than I can assist with the setting(s) that need to be changed to have it register on the TMB servers.

I read this morning, the suggestions from the selection tool thread, to install the tekhd csc from here that's for the S8, so I wouldn't take the chance, but since you did, kudos!
I downloaded and opened the package you linked, and I'm looking at the xml to see if there is a european server.... and looking also at the tmb csc from tkkg's package in source here: https://github.com/GrifoDev/CSC/blob/Nougat/aroma/csc/XAA/system/csc/TMB/system/csc/customer.xml
In that customer.xml file there is the closest thing I found to a tmobile url with respect to wifi, which is "wlan.mnc260.mcc310.3gppnetwork.org" and that url is the same url found in tekhd tmb crc
btw, in your csc package there is others.xml, and in there is: "<CscFeature_Setting_SupportWifiCall>TRUE</CscFeature_Setting_SupportWifiCall>"
I am very tempted to add that line in the tmb csc inside Tkkg's 2.5.0 selection tool, and flash it to my phone to see if that exposes the wifi call setting with my setup..... My pessimism tells me that things are never that easy!
Also, Tkkg announced this morning in one of his SupermanRom threads that he will be updating the csc selection tool for Oreo soon.... keeping fingers crossed that will be sooner rather than later.
Edited:
The csc you linked to is T-Mobile US.... check out the customers.xml file <CustomerData> <GeneralInfo> <Country> USA

The csc you linked to is T-Mobile US.... check out the customers.xml file <CustomerData> <GeneralInfo> <Country> USA[/QUOTE]
So.. it seems the one I uploaded is for the s8 as well. It does seem to work until wifi calling enabled, then it fails to register.

Have you had any luck? I've been able to recreate everything so far in this thread and taking some advice from this one: https://forum.xda-developers.com/s7-edge/development/utility-flashable-csc-selection-30-t3392957. WiFi calling is still a no go for TMB.

Nope, nothing as of yet. ?

Tkkg locked that thread as soon as he posted the updated CSCs for Oreo. The tmb csc in that update doesn't work for me at all. Phone just crashes. Nothing tested and no way to discuss what does and doesn't work. 3.0.0 csc tool can not be taken seriously, unfortunately.

Flashed U firmware to a U1 but no Carrier apps

I have a sm-g715u1 with latest android 11 firmware and flashed the verizon G715USQU7BUC1. Both are latest ota firmware.
Odin (3.141) showed a succesful flash with all 5 bl,ap, cp,csc and userdata put in. The csc file was non home. However, I dont see any verizon apps installed. There were changes and it does show the U version software installed but no verizon apps. I saw no errors in odin and flashed it twice but no change. I did a factory reset from phone app before flashing a second time.
Not sure what i did wrong . I left the SD card in but dont think that matters.
It has verizon splash screen on startup but thats it. The phone is functional but no different than U1
Is this version (3.14.1) of Odin ok for U1 to U flashing?
Should i have factory reset before flashing? Flash from recovery and not the phone software?
Any ideas will be appreciated.

I see that i can no longer access special menus via the dial pad like I did before the flash. Its like a partial install of the userdata file or something.

So things i noticed after the vzw flash: I didnt get the full verizon bloatware and lost some of the samsung unbranded advantages. I have the vzw 4G icon and Hd voice icon during calls and had the video call option. Video calling didnt work and had to call vzw tec support to get it turned on. A ticket was opened to have it done and its now working fine. Before the flash i was told it couldnt be done so flashing to vzw must have helped here. One thing i have noticed is reception in fringe areas after flash in terrible by comparison. It now enters extended network or no signal at all where before it stayed on lte even with 1 bar and could text and call. This must be a PRL difference or something. The unlocked, unbranded version is way way better for fringe areas. In town i noticed no difference.
At this point i could try to enter recovery and wipe then direct to flash the vzw firmware again to see if i get all the bloatware but to be honest the poor signal and tower handoff with the vzw firmware has convinced me that the U1 firmware is better for me overall even if i lose the video calling after switching back.
At least with the U1 version its a little easier to experiment to see what works best.
