I think I found a bug related to Samsung Pay.

I did your method you described in that other thread. Was on XSG so I had to switch over to DBT MM, installed and upgraded and added cards to Samsung Pay and then I upgraded to Nougat using Home_CSC to preserve data. I goofed and only registered one fingerprint.

Turns out that Samsung Pay crashes in Nougat when you try to verify once you add more fingerprints and you're supposed to reset the app. But you can't reset the app because it doesn't go past that start screen.

So now I have to downgrade to MM, setup everything properly, and then upgrade to Nougat. LOL at this point, I would have been better off waiting for XSG's Nougat update instead :D:p
[Samsung Galaxy S7 Edge Questions and Answers] metalboy94:
Sorry for being slow/annoying, but it is again unclear to me - my original CSC (that was on the phone in the box) was ROM, and when flashing Nougat I flashed BTU CSC. In this situation, what would happen if I flash HOME_CSC? (ROM is not among the CSCs in OXA. DBT is, but I guess you knew that already. KOR is also supported by OXA which may explain the Korean SIM error messages).

The last time I used a Samsung phone was in 2013 and the CSC situation was much simpler back then. :rolleyes:
[Samsung Galaxy S7 Edge Questions and Answers] mkoyskip:
I haven't yet installed nougat per jhunkab's instructions (am extremely excited!) but here are some suggestions:

- ROM isn't supported, as far as the OP has suggested, and my own short research. You need to perform a full flash (ODIN) to another that does support SPay

- You WILL lose data so make sure to backup anything that you may want to save

- You can try SS Smart Switch for much, myself I'd also backup anything important the safest way also: create backups by connecting to a computer/copying your files manually/cloud/whatever

- Now you need to download whatever version you care to and perform a full flash - for a full flash don't use HOME_CSC as this won't be a full flash. You must use CSC (again, you will lose all data, just like a factory reset)

- Once your device is running some full version of OXA: BTU, CPW, DBT, ITV,KOR,NEE,XEF,XEO,XEU (not sure about XEU - didn't see this in SS's list) you can now use HOME_CSC later on to save your settings/etc when performing another flash of this or that

- UNTIL YOU FULLY WIPE your device to another country/etc firmware it won't be really fully flashed... Once this is done you can 'sorta' flash anything you like (including your HOME_CSC instead of CSC) and keep your data intact

My CSC is DBT (just like the OP) and is already updated fully so I don't need to worry about this until I have some time on Mon (hope it works for me:cowboy:.

Originally my device was KEN which just wouldn't work so I flashed DBT. The reason I flashed DBT was because whitepages & SSPay wasn't working so I READ through every page (and also used the SEARCH function). My SSPay has been working for a long time only thanks to other XDA members.

I hope this helps you - also make sure to follow the instructions (they are a few pages up - jhunkab's, not mine). If not, just ask

Yeah, as usual I type a lot after a few stouts, sorry....:D

EDIT: latest SS CSC list I found.

Also If I provided any incorrect info PLEASE let me know!
[Samsung Galaxy S7 Edge Questions and Answers] shyam09:
Just a side note from something I experienced when changing region codes to get Nougat-- be sure to fully setup your device before flashing Nougat if you want SPay to work. Which means, flash MM DBT first, and setup the device according to how you want it - fingerprints, SPay (use old versions from around early august and then update in app), and so on.

I had to reflash a couple of times because SPay installing a lower version (from early august) would crash upon start and any other higher version would not go past the start screen, no matter how many times I tried.

Also, if you use Samsung Cloud, it will also install apps (not app data) for you. I think SmartSwitch only does apps as well (not App Data).
[Samsung Galaxy S7 Edge Questions and Answers] metalboy94:
Got it, thanks. Indeed neither Samsung Cloud nor SmartSwitch backup app data so I will have to take some time off to wipe the device and then restore everything.
[Samsung Galaxy S7 Edge Questions and Answers] robstunner:
Just an fyi, the second you factory reset you'll never have Samsung pay working. You'll have to downgrade to mm and do the whole thing over again.
[Samsung Galaxy S7 Edge Questions and Answers] bay96:
I'm a noob so this might a be a stupid question. But if you have a Samsung pay working fine on Nougat, can you do adb backup and then restore it after a factory reset?
[Samsung Galaxy S7 Edge Questions and Answers] robstunner:
You'd have to ask someone else. I'm sure someone will chime in.
[Samsung Galaxy S7 Edge Questions and Answers] jhunkab:
Confirming/Clarifying:

XEU is also part of this OXA - i see it in my Phone Info App - refer attachment screenshot by other user (look for "Available CSC Code Field"), it shows up

like

this (my CSC codes are DBT) on my phone info app.

Got Nougat on XSG csc (country UAE /AE)! Upgraded from MM using the OTA update without issues. In fact seems to have fixed my old spay issue where I could NOT buy any giftcards through the spay app. But I just tried it and accidentally ordered myself some giftcards lol
[Samsung Galaxy S7 Edge Questions and Answers] yeltrah123:
I was planning on purchasing the S7 or S7 Edge from B&H but I see SM-G930F and G935F, but I am not sure if the versions of the ones they're selling supports Samsung Pay on the latest nougat firmware.

[Samsung Galaxy S7 Edge Questions and Answers] makkonen:
Can you tell me what versions of SPayFW and SPay you're currently running? I had stuck with old versions (FW 2.4.02/App 2.2.01 I believe) on my XSG CSC 935FD, because it was working fine (and I was able to keep using my AmEx). But I took the Nougat OTA, and then they failed to run. I didn't take the samsung pay update that was requested when I first booted into Nougat, and then couldn't find a way to get back to it, so I installed the latest versions from apkmirror (2.7.10 and 2.7.46), but now I get 'failed to connect to server' if I try to do anything. I can see my cards, but I can't use them, and I can't add new ones.

Going to try to downgrade now, but maybe I traded working samsung pay for blue light filter... which is a trade I'll willingly make at this point. I'm unwilling to wipe and go back to mm just to avoid pulling out my credit cards, I've decided.

Edit: I guess it doesn't matter. Downgrading with adb install -r -d or pm install -r -d still throws an INSTALL_FAILED_VERSION_DOWNGRADE error, so it looks like I'm stuck with the versions I've got. Oh well.
[Samsung Galaxy S7 Edge Questions and Answers] nuetron:
Latest version on MM for Samsung Pay is 2.5.12 and Samsung Pay Framework is 2.7.12 (these versions are updated through the app itself, not sideloaded). If you install anything above that, it will not work. I've tried before and had to wipe and redo. For some reason apkmirror has builds with very high version numbers, maybe for testing?
[Samsung Galaxy S7 Edge Questions and Answers] makkonen:
Or possibly from non-us versions? Oh well... Should have done a little more research and not gone in blind. Thanks for the info!

No one in the US has been able to get Amex cards working with the more recent versions, right?

Edit to add: Since my framework wasn't too far ahead, I attempted to save my data with 'pm uninstall -k com.samsung.android.spay'. When I tried to reinstall, I got INSTALL_FAILED_ALREADY_EXISTS. After a reboot, I was able to reinstall SPay 2.5.11 (Can't find 2.5.12 in the wild), but when I opened it, my data was gone. And now I can click the Start button, but it just spins the loading animation and never goes any further. Which sounds like about the same problem everyone has been having on 7.0. Anyway, just letting people know, 'pm uninstall -k' seems about as ineffectual here as 'adb install -r -d'.

Maybe this'll be what finally convinces me to root. Silver lining.
[Samsung Galaxy S7 Edge Questions and Answers] nuetron:
Yeah, US amex does not work ever since the samsung rewards update (I believe that was 2.3). I'm on DBT MM so i'm patiently still waiting. Hopefully when it comes out, I can still use my visa/mastercards.
[Samsung Galaxy S7 Edge Questions and Answers] oplix:
Downgraded back to DBT MM (CSC+repartition in ODIN), installed Spay/Framework (apkmirror August 4th release spay/framework), installed, added cards, upgraded Spay (within app). Now installing BTU Nougat using HOME_CSC. Hopefully it will end up working. Fingers crossed.

I am on XSG and upgraded from MM to Nougat yesterday. I was and still am on SPayFW 2.7.10 and SPay 2.5.11. Everything but AMEX seems to be working fine which was the case on MM. I haven't upgraded to 2.5.12 yet. Been a bit reluctant due to the frequency in which stuff breaks on upgrade.
[Samsung Galaxy S7 Edge Questions and Answers] ChiAn:
Yep I was on the same versions of Spay and SpayFW as you.

Didn't know SPay 2.5.12 was out until i saw your post so I went into the app and checked for updates. It says it is a UX visual updates for Android N. Installed it and added a new CC to it without issues. I don't have an AMEX card to test (just AMEX Serve which says not supported).
[Samsung Galaxy S7 Edge Questions and Answers] nuetron:
US Amex does not work on 2.5.12 (on MM DBT).
[Samsung Galaxy S7 Edge Questions and Answers] jhunkab:
I haven't seen Nougat release for INS (India) yet.. but here is the story related to Spay in Indian release.

http://www.androidheadlines.com/2017/01/galaxy-s7-nougat-update-brings-samsung-pay-app-india.html

It would be interesting to see if the cards enrollment remains limited to India based cards or other country based cards get through in that release.
[Samsung Galaxy S7 Edge Questions and Answers] xxhorseriderxxx:
got the XGA OTA and no problems so far. Nougat is definitely smoother, and samsung pay works just fine. I updated to 2.5.13 before updating. One thing though: remove Good Lock before updating. I encountered a scary black screen and had to hard reset before I could even interact with the phone (the screen was black). After it turned on again, Good Lock was automatically uninstalled.
[Samsung Galaxy S7 Edge Questions and Answers] hamilton2130:
Hi guys, I have went through the instruction but Samsung Pay says:" You cannot use Samsung pay with a SIM card from other counties. Insert the SIM card from Korea." Actully my carrier is CT-Mobile which using the T-mobile network in U.S. Could anyone help me? Thank you very much!
[Samsung Galaxy S7 Edge Questions and Answers] HalVllVler:
Thanks for this [MENTION=959855]oplix[/MENTION]. I started from step 17 (was already fully up-to-date on DBT). SPay seems to be working fine, sans Amex. Everything seems smoother and a bit quicker. Now, on to moving my wife's S7 to DBT.

Great thread; very informative!

---------- Post added at 04:58 PM ---------- Previous post was at 04:56 PM ----------

Did the black screen appear after the screen with the animated gear and the app updates? I did the BTU update to Nougat with Good Lock installed and didn't experience any problems, but did notice that it is now uninstalled.
[Samsung Galaxy S7 Edge Questions and Answers] chadmcskateboard:
I am on 6.0 still and wanting to flash nougat. The 7.0 XSG (UAE) has spay, does it have whitepages support?
[Samsung Galaxy S7 Edge Questions and Answers] yubeie:
nope!
[Samsung Galaxy S7 Edge Questions and Answers] mkoyskip:
Did find this somewhere:

I'm on DBT and find the whitepages works pretty well for me. Sometimes takes a few seconds when making a call to an unknown number before showing info but it seems mostly correct. There have been a few times the info: Kaiser Permanente called me and it only showed "School" as the caller, have also received a few call listed as SPAM/etc that weren't (mostly I just block them but depending on the calling number I'll wait to see if there is a voicemail).

Personally I'd love to have wifi calling but I don't remember seeing any posts mentioning this is actually working (USA, ATT).
[Samsung Galaxy S7 Edge Questions and Answers] mgfjd:
Thank you for the info. so my choices today to get Nougat update through SAMMobile is UAE with Spay and UK without Spay. I saw India and Thailand for the 930FD with nougat. Does anybody knows if Spay could be installed? I heard India has Wifi Calling as well.
[Samsung Galaxy S7 Edge Questions and Answers] mkoyskip:
Just a reminder that in the US [again, as far as I know] we can't get wifi calling. Don't think we can get volte either. I would just love for somebody to contradict me and say it isn't so!!! I've done a fair share of research and have yet to find any valid info. YES, I know I'm slightly off topic (sorry) but as this issue has been queried a lot thought I'd throw it in - just in case somebody has an answer.;)

Myself (DBT) I've been waiting patiently for the nougat update but if it doesn't come next week I guess I'll switch up. Been super busy but I just have "THE NEED" for something new as I haven't done any tinkering for a while. Perhaps as soon as I reflash the update will magically appear....
[Samsung Galaxy S7 Edge Questions and Answers] Misterjunky:
re: wifi calling and volte

I posted a custom rom in the S7 / S7 Edge forum which has

perfect and proper wifi calling and volte.

https://xdaforums.com/s7-edge/development

The wifi calling and volte features have only two requirements:

Please note: these two features will not work if you are using

the official stock unrooted samsung firmware.

1: You must be using a Tmobile sim card.

2: You must be on the Tmobile network.

Good luck,

Have a great day!
[Samsung Galaxy S7 Edge Questions and Answers] xxhorseriderxxx:
Yeah, it happened after the bootscreen with the gears, and after "updating applications". The screen just went black, like, nothing shown, black. I thought I'd bricked it because the hardware keys weren't responding. I cant tell if it just finally crashed or what, but it eventually turned on holding the power and home button down together. It was a real long wait though.

The OP of duel boot also has a TMo mod that works on most 7.0 re based roms but only with us sim and service.
[Samsung Galaxy S7 Edge Questions and Answers] mkoyskip:
Thanks for this also. I document anything of interest based on my current device and may use this further on down the road. The GS7 is the only android device I've ever owned that I haven't rooted. Can't wait to because this phone could just Rock & Roll... I can sometimes get almost 2 days currently, can't imagine the life/etc after rooting. Was getting 2 days easily on my GS4 (not sure on my rooted tablets as I don't use them much - sometimes weeks without a charge).

Hello all, I am in the U.S., using an S7 Edge (exynos) from Italy. I have AT&T.

I just want to be able to use samsung pay and have white pages support. I was told a few months ago that I could flash Germany 6.0 (DBT) and I would be able to use spay and it would also have whitepages support. I am now waiting for Germany 7.0 (DBT) to appear on sammobile. Just making sure, this is what I need to be waiting for, right? Because some people are telling me something about how I can flash BTU, and others have said spay doesnt even work in Germany so I am confused.

No one knows if the 7.0 dbt version will continue to support spay....but going by the trend it will most likely.. so stay put.

Hey I got a question. I flashed a different country firmware on my SM-G935F and of course changed the csc. I was wondering if you can revert back to the default firmware via Odin and get back original csc.
[Samsung Galaxy S7 Edge Questions and Answers] Lieutenantdaan:
You can root and change csc

Flash original firmware after that
[Samsung Galaxy S7 Edge Questions and Answers] yeltrah123:
for Samsung pay so no root. Can I do it?
[Samsung Galaxy S7 Edge Questions and Answers] Lieutenantdaan:
Actually spay doesnt work once you trip knox

By flashing firmware via odin you will remove root and will be back to stock, but knox will stay tripped [emoji53]
[Samsung Galaxy S7 Edge Questions and Answers] yeltrah123:
I'm saying can I flash back to original firmware and csc? I haven't rooted yet, and i'm not looking to.
[Samsung Galaxy S7 Edge Questions and Answers] Lieutenantdaan:
When you flash a stock firmware with single csc you will get the country its meant for...

If you flash a multi csc and your current csc isnt part of it, you get the default country from that multi csc...

Cant find the link, but it has been discussed in other threads, pls search around for your exact scenario...
[Samsung Galaxy S7 Edge Questions and Answers] yeltrah123:
i'm confused now. I'll just flash original firmware that came with the phone via odin (bl, ap, csc, bp)
[Samsung Galaxy S7 Edge Questions and Answers] mkoyskip:
Sorry I'm late to the game lately, meaning that I don't have time to reply as often as I'd like:

- DO NOT ROOT your device if you want KNOX to work, only use Samsung Firmware to change your location/etc

- You CAN USE any Samsung Firmware on your device as long as it is NOT ROOTED, otherwise this will trip the KNOX

- Make sure to use the correct Firmware for your device. US firmware WILL NOT WORK on the international GS7, and vice-versa, they are completely different devices/phones. This means that they are COMPLETELY DIFFERENT hardware - just don't do it!!!

For example: if you're using a USA version ATT/Tmobile/Sprint/etc don't flash an international firmware. ALSO if you're using an international variant don't flash ANY USA firmware to this device. NEVER, EVER, just don't do it or you'll F**K it up.

I've been using Germany (DBT) for many months now: Whitepages work, SPay works, and has been working for a very long time. My device was originally Kenya/Africa (still tells me that the manufacturer was Vietnam). I originally flashed perhaps XSG (United Arab) but ended up using DBT because it works (in the USA at least) for whitepages & SPay. And it has continued to work without any issues at all (for myself at least).

PLEASE take some time to read through this thread AND FOLLOW THE DIRECTIONS as it will help me decide whether or not to answer these posts. Don't get me wrong, I'll answer when I can - but take some time to do your own research before this. REALLY!! You (not personally) need to make an effort.

The instructions on how to flash are readily available in the previous posts, including how to ODIN, which files to flash, etc.

EDIT: sorry don't mean to sound like a ****. Anybody can reply to this and/or shoot me a PM, will reply ASAP. Can take a few days for me to get back to you.
