Are you sure? I have had many problems when I tried the marshmallow PHN CSC on the first 7.0 beta.

I think it's better to wait for the proper Nougat PHN CSC or make the switch to BTU CSC
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Lennt:
What's the difference between these anyway? To any non-(PHN or BTU) phone, there's no difference, right?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] founz:
I flashed the rom today, but the WiFi and camera were not working. Back on MM again...

Since some people are having problems with the Netherland version: Would this way of installing Nougat also work with the BTU version that's making the rounds here on XDA and on other forums? Or are these already essentially the same since you only exchanged the HOME_CSC?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] 5770mp:
The same is to me? I'm in USA using t-mobile network..

I need to flash DBT csc along the firmware in message 2? Do not include the csc found in message 2? Thank you. I'm on XSG csc now with the original firmware, but no s pay.. I have read s pay need to work on that csc... ( correct me if I wrong- it's has difrent bends (att-tmobile)? Tnx (that you I asking you if I need to flash like att...)

Edit: is more recommend that I download the BTU 7.0 or its the same?

I flashed first PHN CSC but have a lot of problems, when i flash after OXA csc, the device became normal.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] jhunkab:
OXA - is a multi-CSC and includes BTU, CPW, DBT, ITV,KOR,NEE,XEF,XEO,XEU CSCs

I had converted to DBT from ECT few months back - by flashing DBT CSC (instead of HOME_CSC, which I have been doing ever since to protect my data and setup).

This is what I did to upgrade to Nougat.

Updated my Phone to latest DBT - AP-BL-BPLB/CP-BPJJ/HOME_CSC- OXJ1BPL1 using Odin.

Then downloaded latest Nougat for BTU - which has OXA CSC .. hurrah!

Extracted files and flashed: AP-BL- DPLT/CP-DPLT/HOME_CSC- OXA1DPLT

Phone kept DBT.. and so far it seems SPay is intact too.. no strange error or behavior. Will see in next few days if the payments work or not.

I am on US AT&T service.. service seems OK so far; You can use the same process for T-Mobile.

Will edit this if I find something new.

Hope this helps.

Edit: Confirming that Spay is working. No issues detected in networking or calls.

The way Henrik said it

Get your CSC. Download the latest one, I've tried with an older CSC, it didn't work. Download the newest firmware. Once all is done it should look like this....

BL - Nougat

AP - Nougat

CP - Nougat

CSC - Marshmallow HOME_CSC (LATEST of choice)

Anyone got problems with the missed call notification on Nougat?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] tenchi71:
This works. Did same last night on my DBT Edge. Flashed the OXA firmware using the HOME_CSC, and it kept my DBT CSC.

Only thing I did different was after it was done upgrading and i had full control of the phone was to reboot into recovery and clear cache.

HOME SCS compatability

Just had a question... can i use my HOME_SCS ( which is android 6.0.1 Marshmallow ) with the main package provided in the #1 post (Android Nougat ) ?

Okay i got that thanks one more question... if i flash the UK Nougat rom now and when my carrier updates to Nougat can i flash only the CSC file or do i have to flash everything again ?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] MistaJae:
You have to flash the whole firmware again as changing CSC wipes your device anyway
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Lennt:
Not necessarily. If you follow OPs instructions here, your device should not get wiped.

I'm just not sure if flashing your own region's 7.0 HOME_CSC as soon as it's released will reset your device. Will this count as "changing" the CSC? For example, is going from 6.0.1 DBT to 7.0 DBT a "change"?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] MistaJae:
If you use 7.0 with your current 6.0.1 CSC, updating the same CSC to 7.0 (when it becomes available) WON'T wipe your device.

If you install the full BTU update (incl. BTU CSC), flashing your carrier's 7.0 CSC (when it becomes available) WILL wipe your device.

Hope that's clearer
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Lennt:
Yes, thank you! I have a couple follow-up questions though, as I don't quite understand the difference between CSC and HOME_CSC.

Let's say I flash 7.0 BTU AP, BL, CP and 6.0.1 DBT HOME_CSC. After that, I have a working 7.0 ROM, although it's quite a patchwork at that point. Right?

Then, at some point in the future, the DBT 7.0 gets released. I don't like patchworks, I'd like for my system to be perfectly equal to the system I'd have if I'd just wait for the regular OTA. To achieve this, do I need to flash...

7.0 DBT AP, BL, CP and HOME_CSC?

or

only the 7.0 DBT HOME_CSC?

But what about the CSC, then? After all, I didn't touch the CSC file at any point, only the HOME_CSC file. Do I need to "update" the CSC as well in order for my system to become "complete"?

I downloaded the latest firmware for my s7 edge branded H3G(unlocked network) to flash via odin and I'm afraid due to CSC file named OXA.

After I unzip I got 5 files(AP,BL,CP,CSC,HOME CSC)...Please,give me a replay because few days ago my phone starts to reboot a lot and I already done a factory reset and wait to flash this firmware.

It will brick my phone if I flash this noughat firmare?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] daLareid:
I'm thinking of flashing the new BTU 7.0 firmware on my unlocked exynos duos phone which currently has an Arab firmware, I know flashing a different CSC will wipe my data but I'm wondering if it's ok to flash all files including the HOME_CSC included in the BTU 7.0 firmware? Don't want to risk bricking it by flashing a different Home_CSC.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] deathst:
Flashing the BTU 7.0 FW will wipe as it changes your CSC, In fact it is best not to mix different versions of CSC and keep to the same provided by the FW files. It causes errors esp, if you use older CSCs.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] daLareid:
Thanks for the reply on both threads, but I'm a bit confused now. So it would be safe and the best choice for me to flash all files from 7.0 UK BTU fw including HOME_CSC?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] deathst:
You can flash the entire thing, just use the OXA_CSC instead of HOME_CSC! There is no harm reported from doing so so far. My Device is like yours G935FD Singapore, now running completely on BTU 7.0
[Samsung Galaxy S7 Edge Guides, News, & Discussion] daLareid:
Thanks a lot! how did you back up your stuff? I mostly care about my pictures and videos on gallery, already backed them up manually and through Smart Switch. But I was wondering since you probably already restored your stuff, do you know if the pictures and videos in the Gallery remain with the same dates and still sorted by date taken?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] deathst:
Smartswitch to external SD then restore once flashed. Eh.. Things look fine here after I restored it still. I've thousands of photos, I really don't see anything out of place.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] MistaJae:
IIRC you always need to flash either CSC or HOME_CSC when updating through Odin (along with AP, BL and CP).

HOME_CSC is flashed when you are only updating and want to keep your current CSC (non-wipe, kinda like an OTA).

CSC is flashed when you want to change the CSC code or to start fresh (as it completely wipes the device).

In your example scenario, you would need to flash DBT AP, BL, CP and HOME_CSC. That would give you your "complete" device whilst preserving your data.

FYI - I always flash BTU firmware with the latest EVR HOME_CSC (as EVR is slow to release updates).
[Samsung Galaxy S7 Edge Guides, News, & Discussion] daLareid:
That's exactly what I just did, backup to external SD. Going for it then, thanks! btw I should use UK BTU 7.0 fw HOME_CSC and not the regular CSC, right?

OTA Updates

My S7 edge was originally on XEU (UK/Ireland) marshmallow. I've flashed 7.0 BTU firmware, all files, but Phone Info still says my phone is XEU. Will this stop OTA from working?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] gyoung:
lol. try and run system update to see if it applies the OTA? if not, re-flash it again?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] jhunkab:
no it won't, you should get OTA.

OXA is a multi csc and supports BTU, CPW, DBT, ITV,KOR,NEE,XEF,XEO,XEU csc

so if your firmware's csc code (check using phone info app) is one of these, then you just got official Nougat update :)

just flash with Home_csc file, if you like to retain data.. else go ahead with CSC file for full wipe.

Thanks for the help.:good:
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Painman1963:
The pin should stay active. The password he said to try was "default_password" without the quotes. The reason you have a numeric keyboard is because you have a pin set
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Tareq.tfn:
I must Use CSC File or HOME_CSC File ???
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Lennt:
Both is possible.

CSC will wipe your device like a factory reset, but is considered a cleaner upgrade, as you'll have a "complete" system. You'll receive OTAs afterwards.

HOME_CSC won't wipe your device, but you'll not be able to receive future OTAs, meaning you'll have to flash every update manually. Also it's kind of a patchwork solution, as you'll have mixed system components from two regions, which may or may not cause some bugs.

which APKs are you using for Spay? 2.2? 2.4?

---------- Post added at 09:16 AM ---------- Previous post was at 08:53 AM ----------

Just an FYI. I just did this and you HAVE TO have Spay correctly installed on MM before doing the nougat FW update via odin.

A factory reset will kill your ability to reinstall samsung pay, and with the DBT CSC, you will lose the function to have Caller ID via whitepages.

Back to square one for me.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] tenchi71:
I'm not. I don't use SPay.

Also, I did NOT use an older MM DBT HOME_CSC... I used the OXA Nougat HOME_CSC when flashing.

Go to updato.com.

Download the latest Canadian marshmallow firmware i.e. XAC and extract in a map.

Download this Nougat firmware from #2 and extract also in a map.

Read carefully #1 & #2 from OP

Start Odin 3.12.5 (included in this aforementioned Nougat firmware)

Select AP, BL & CP files from Nougat

Select CSC_XAC from your marshmallow firmware (because I presume you would change to a Canadian ROM)

Flash

Enjoy Nougat

Phonecalls not working!

HELP!

I couldn't wait for the OTA, so I did this last night. It was quick and easy, without any issues. Was very happy, too, because everything was working very smoothly. Or so I thought...

I tried to make a phone call this morning. Whenever I initiate one, it drops instantly ("Connecting... CALL ENDED")

When people call me, they hear the waiting tone... but nothing happens on my phone.

- I can send send and receive text messages

- 4G connection is fine

I already tried a full wipe via recovery... but to no avail.

I wonder if there's an issue with the Phone app? Or framework? But I'm not an expert.

UPDATE:

I figured out that it's something to do with 'Network Mode' in Settings > Mobile Networks.

The issue only presents itself when '4G/3G/2G (auto connect)' is activated. When I switch to any of the other modes, I can make and receive calls again...

Is this a known issue and is there a way to resolve it?

Any suggestions? I would really appreciate some help on this!

I bought my phone in The Netherlands by the way.

Many thanks in advance.

Thanks you
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Lennt:
I think it's both. The problems do occur with some networks, but only if MM and N files are mixed. I've seen a lot of comments from people who flashed using the Nougat HOME_CSC instead of the Marshmallow one, and afaik none of them has had any problems with phone calls.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Caemgen:
Thanks for the replies above.

I'm on VodafoneNL, so that may be it...

Quick question: after flashing these files with Odin, will I still receive OTA updates?

In other words; when (if) an updated build becomes available that fixes this VoLTE issue, will I automatically receive it?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Galactus:
Yeah I guess I should have elaborated. So far I've seen users on Indian networks, Australian and US networks that can't receive phone calls on 4g when mixing marshmallow CSC and nougat odin files. Romanian users and dutch seem ok. UK users who flash marshmallow CSC have no problems making phone calls but don't have VoLTE (EE Network).

If you had VoLTE on BETA 1 then flashing BETA 1 CSC + nougat files will give you VoLTE and it should work properly. That is what I did to get VoLTE and WiFi calling for my network (EE UK)
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Lennt:
German (DBT) users were also having problems with that, I've read about that in a German Android forum. Using Nougat Odin files + Marshmallow CSC led to problems with making phone calls.

People who flashed Nougat files + Nougat HOME_CSC didn't report any problems.

One guy who had mixed MM and Nougat files reverted to Marshmallow to get a clean slate, meaning he flashed MM files including the MM CSC. He then again flashed Nougat files, this time using the Nougat HOME_CSC, and everything - including VoLTE and WiFi-Calling - worked perfectly after that.

Noob country change

I was thinking to change country for my S7 edge. I came to this thread and this is what I managed to understand plus the subsequent questions that popped up in my mind, so pls. correct me if I am wrong.

1) Each phone has an IMEI and serial number that are used with Smart Switch to restore original FW.

2) Does the product code (obtained with phone info) ie: SM2G935FZKAAUT tell Smart Switch which firmware to flash or is it the IMEI + SN?

Wanting to change the country, a region specific FW must be obtained from updato.com, then the 4 files are to be flashed with Odin 3.12. At this point the phone will completely reset erasing everything unless a custom CSC file is used, in which case all the settings and apps will remain.

3) Once reset, will the product code change or will it remain, as per the example, AUT and which, if, OTA updates will be available (original AUT or modified country)?

4) If it remains (as per the example) AUT will OTA updates work?

5) If it changes will OTA for the flashed region work and what will Smart Switch do in case of an emergency recovery?

You rightly may ask why my post? My 935F has never been flashed but has rcvd official updates OTA. When I checked with Phone Info the "Original CSC Code" and the "Available CSC Codes" fields are blank and the "about device" "software update" says that the latest updates have already been installed. The CSC country is Switzerland/CH, Active and Firmware CSC are AUT. Empty fields, in my opinion, denote problems and my country is Italy but will sooner or later change.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] CrEaTiiOn_187:
Smart Switch checks the software that's on your phone and will update with the software that matched the CSC from your phone. If you e.g. use Android 7.0 update with a different CSC like AUT to keep your data you will not get OTA updates as the software and CSC mismatch(not from the same country). However if you flash all 4 files AP.BL.CP and CSC and do the reset you will recieve OTA updates from that country.
[Samsung Galaxy S7 Edge Guides, News, & Discussion] Berget:

Will an CSC from an other country mess with Google Play or other apps?
[Samsung Galaxy S7 Edge Guides, News, & Discussion] lonzar:
