Activating Reliance JIO - VoLTE on S7 Edge with non VoLTE firmware

Hello All,
I have S7 edge bought from Singapore. I have downloaded Phone Info app and following are the details :
Product Code : SM-G935FZSUXME
CSC Code : XME
Available CSC Codes : CAM, GLB, MM1, MYM, SIN, SMA, STH, THL, XME, XSP, XTC, XTE, XXV
CSC Country : Malyasia
I have got Reliance JIO card and trying to activate it. Unfortunately I cannot do it since current version of firmware does not support VoLTE. I need to move it to some firmware which supports VoLTE.
Let me know if you need any other information in order to give me suggestion on how can I activate my Reliance Jio card, without rooting the phone. In case rooting the phone is the only option, I would like to know if I would continue to get the updates given by Samsung in future ?
Thank you in advance.

Yes it is possible to do it without rooting you just need to install the CSC Firmware of the country you want to change it to, using ODIN i have mentioned the steps in a previous post its not a big problem and very easy to do.
PS- the India Firmware supports VolTE but you must ask if you can install it over even if the phone doesnt support that version, i think you can but i am not sure

Hi Utkarsh,
Thank you for your response.
Whom should I ask ?

See the thing is i have a solution, and i know the Indian firmware version supports VOLTE, It is about finding the firmware version of the CSC that the phone supports.. What i am not sure is if you can install a CSC fimrware that is not supported in your phone, for that send a PM to mods or people who know. I will list the steps that i did
- You dont need to flash your ROM, you can change your firmware to INS CSC and it works.
1) i used the Phone Info App (Download from the Google Play Store) and saw what CSC Codes were available for me to change to.
2) I downloaded a new firmware from Sam Mobile - You can google for them entering your model no - G-935fD, i am not sure if they are available here in XDA as well
3) My phone supported India CSC (You can see supported CSC's using the Phone Info App so i downloaded the India one it could be different for others.
4) I then downloaded ODIN and used the tuorial in this forum to flash my phone and change the CSC code.
https://www.youtube.com/watch?v=7SK3IMprKVQ this is the link with a step to step guide.
5) After that i factory reset my phone and downloaded the July Update Patch.
My phone after that has been able to make calls and i can see the VOLTE symbol, depending on the firmware it should either automatically come or you might have to manually enable it.
Hope this helps everyone else also. Factory reset usually helps and downloading the latest update too..

Hello,
I did see this post over here in XDA, but my issue is that my phone does not support India CSC. As mentioned in the original post in Phone Info shows me the following available CSC codes (Missing India ) :
Available CSC Codes : CAM, GLB, MM1, MYM, SIN, SMA, STH, THL, XME, XSP, XTC, XTE, XXV
Hence I am not sure if installing Indian firmware through ODIN will help or not. Do you know if that will work ?

I can confirm that is possible to change via Odin without root the CSC even to one which isn't currently available. Yesterday I've changed my CSC from ROM to ORO in order to have access to VoLTE and VoWiFi. I'm not rooted and OTA update it's working. One thing to cosider is that the phone will reset to factory settings.

Ok perfect. I am downloading the Indian version of the firmware. Will keep you updated. Just hope that my VoLTE get's activated !! Keeping my finger's crossed !!
Also, thanks for the quick response.

Depending on network, sometimes it's necessary to send a SMS or call a special number in order to activate VoLTE.

Hey I was successfully able to reset my CSC to INS (India). So thank you very much for that. But I am still not able to see the VoLTE option in my Dialer -> More -> Settings, which most of the people have confirmed that they see it.
I am on Reliance Jio and Idea in Gujarat, India Are you aware what should I dial to enable VoLTE ?
My phone is getting an update, just hope that it helps to get me to see the VoLTE option !!

It should be in Settings/Mobile Networks

If you phone is not rooted you needed Volte option in your device than yeah you needed INS CSC to get option in Indian Carrier.
So simple and best way is to Download your Samsung S7 edge INS firmware from sammobile.com and enjoy.
or you can try custom Rom so try exyfire Rom for S7 edge and than flash INS CSC whose Zip is available to download.

Just download the following zip file and flash it using TWRP. In the Aroma Installer choose Indian CSC option and you are ready to cruise on the Jio craze. No need to flash any FW

Dont worry just back up your phone, download the latest OTA updates and factory reset your phone , it should work seamlessly the Indian CSC does not have any setting to turn it on/off , let us know how it went

I am facing the same issue. I am still not getting VoLTE option. I flashed phone with latest Aug 2016 INS firmware from Sammobile which has July 2016 security patch. Once flash without factory reset, second time flash followed by Factory Reset. Still no luck.
Later check with Samsung and Jio Helplines and they say S7 Edge will not have VoLTE option under setting, it is active by default, but none has an answer as to why VoLTE logo doesn't show up? If i have to make calls, the same gets routed through Jio Join App and if i uninstall the App the calls doesn't go through at all.
Some Expert please help!

I have the Samsung S7 Edge SM-G935FD bought from UAE, (Made in Vietnam) and it has multiple CSC but not for India (INS not present in CSC list).
I was getting 4g but no Volte, so no calls/sms.
I read this entire thread last night. Got the latest India firmware.
Flashed as per post #42 of this thread. Wiped cache,
After rebooting, I got the LTE sign, but still no Volte, checked for latest updates, I was all up-to-date.
Put phone on flight mode and back on.
And voila, Volte!!
Thanks to @utkarsh_86 and @gandhipurav for this amazing thread.
And everyone else who contributed here! You guys did an amazing job!

Hi everyone,
It is possible to change the CSC and firmware without ODIN or rooting.
1. Download Samsung smart Switch.
2.Click more on the right corner
3.Click Emergency Software Recovery
4.Click Device Intialization
5.Put your Model no
6. You need the local INS serial no ( Check Google with model no- I got one from a face post for SM-G930FD)
7. Click Ok, and follow instructions.
8 After Phone restarts clear cache memory. (Check Google with phone model)
9 After phone restarts Volte appears.
Thank you.

S-Pay UK G935F Issues

Afternoon all,
I was made aware by a friend that Samsung Pay now works in the UK, the problem I have is that
1) I cannot see the app in the market (Gplay or Galaxy)
2) After sideloading I get the following error when I open the app.
:Invalid SIM Card
Failed to read your phone number from your SIM card. Check your SIM and try again.
A little bit lost on where to go from here.
Phone Spec:
SM-G935F ZKAXEU
AP G935FXXU1DQD7
CSC G935FXEUDQD1 [XEU]
Kernel : 3.18.14-11104523
Android 7.0 Build NRD90M
Not rooted
Knox 0x0 (Untripped)
Any help would be appreciated!

Which ROM do you have installed?
I have SuperMan ROM, and Samsung Pay is working fine, in other roms I had the same problem that you.
With SuperManRom, I installed, changed the CSC to my country, and turn on the "Magisk hide" and that's all, working.
I do not readed before, you rom is stock not root.
Well, the other question is, do you tried to restart the application, delete memory cache and data?

Just attempted clear memory and restart app but to no effect.
Interestingly in phone the settings under "my number" it just says ... "not available" which I presume is unusual.. Faulty sim?

Mysterious

I think it's because your on XEU Firmware.
I'm in UK and on BTU I'm rooted but can install Sam pay from play store fine
(Also no SIM number in settings)
BTU = direct from Samsung ( I purchased from giffgaff)
XEU or any other UK related csc = not direct from Samsung
So things might arrive slower for you
( Ignore that it says I have s8 I'm on an s8 port )

I am on BTU ... no root ... and I have the "no SIM number" .... problem

Play store says it's incompatible with my device

Re-Flash
my guess is the firmware!
download the lastest BTU (UK-unbranded)
flash it once then:
1 - set up the phone and factory reset the device fron settings app.
2 - power it off on the new setup screen.
3. hold down the power + home + volumeUp
4. check which CSC the phone have.
5. if it's BTU = setup the phones for usage.
if it's not BTU, then clear chach and flash BTU from beginning. and try again.
when all this annoying thing is done
after seting up the device. download Spay from playstore or apkmirror.com
that's what i would try.
if you use odin then the phone should not be rooted
(just have to say, everything is on your own risk)

It could be the SIM card age ....

No rooted

I cannot read my phone number from SIM with any app and I cannot use Samsung Pay ......

I have ordered a replacement SIM which will be here in a few days so I will update, if not I will go down the reflash route.

This is what I did and it worked for me .. Please note , all of your data will be erased (I.e. factory reset) so take back.up if you want.
1. Power off and remove the sim tray.. Please ensure you have a Indian sim in the tray.. I used Airtel
2. Goto recovery , HOLD bixby button and Volume up together and power up
3. In recovery , chose factory reset .. This will give a warning and then reset everything
4. Chose power off in the recovery and insert sim tray with Indian sim .. you should do this before booting up as your CSC will be configured when you will start
5. Power on the phone , it may goto recovery again.. Chose to restart to system now
Everything will be configured to INS CSC now .. Samsung Pay works now ..
This worked for me , I had imported S8 from UAE . I don't take any responsibility for any damage in the process please .. just sharing what I have learnt from this forum. THANKS

I'm in a similar situation, have imported a Samsung S8 from UAE and would like to change the CSC to India. Will be getting my hands on the device in 1 or 2 days.
Are you sure the procedure explained above works?! Seems too simple
What was the UAE firmware version. I read somewhere on sammobile that the samsung s8 bought from UAE cant be changed to Indian CSC, and I also read the you should first insert a UAE sim card into the phone and then later you can insert any sim.. lots of confusions. Please do let me know your thoughts.
I'm very familiar with rooting phones so flashing new firmware and CSC using ODIN isn't going to be complicated for me.

Yes, it's simple and it works. Now a days most of the firmware are multi CSC so it gets configured automatically. Make sure you put a India SIM before powering on the NEW phone and you may not need to follow the above procedure.. It will get configured automatically

Hey! I purchased a Galaxy S8 G950FD from USA. I'm gonna receive it in few days. The CSC has OXM in it but not an Indian one.
It's being used with an US SIM currently. Will I ever be able to activate SPay in it here in India? Inserting an Airtel SIM (Indian Network) and following the steps you mentioned will change it to INS, thereby enabling me to use VoLTE and SPay?

Hi,
Appreciate your effort in letting us know what could be done in rectifying this issue. I have just bought an S8 (SM-G950F) & I have been using it in India. I didn't kind of notice it initially but as time went by I just thought I'll set up "Samsung Pay" and noticed that I could not get through it at all. The application would open and check availability and would immediately give me a reply stating "Temporarily Available, Try again later". Had been frantically searching for a work around I stumbled across your instructions.
Did exactly as you had mentioned but to no avail. Everything seems to the same as it was just before I did a factory reset. I don't know where I have gone wrong but if you could probably try to help me out. Just for my clarification, after the factory reset, are we supposed to set up the phone as a new one or can we restore the settings and applications. If you could let me know, as it has been very frustrating since the last few days. I haven't been able to use Samsung Pay nor have I been able to use the Oreo Beta Program nor any updates.
Will look forward to your reply.

Hi,
Appreciate your effort in letting us know what could be done in rectifying this issue. I have just bought an S8 (SM-G950F) & I have been using it in India. I didn't kind of notice it initially but as time went by I just thought I'll set up "Samsung Pay" and noticed that I could not get through it at all. The application would open and check availability and would immediately give me a reply stating "Temporarily Available, Try again later".

That means yours is the US version.
My phone's model number is G 950 f, which is a international version.

Unfortunately this didn't work for my s9plus unlocked snapdragon usa version with indian carrier jio, I tried hard reset once with nio sim and twice with airtel sim, but all in vain.

Can i flash indian region firmware on my galaxy s8(uk region) csc - BTU

I have galaxy s8 imported from UK. I live in india and its unlocked. Soo volte doesn't work in my s8. I tried to flash indian firmware but did something wrong and lost imei and baseband info. But managed to undo that mistake. I think i forgot to turn on USB Debugging. That was my mistake i think.
Sooo anyone who tried different region firmware?? I need to know that if i do that my phone wont get bricked.

Changing the region firmware should be easy.
- Make sure ur phone is unlocked.
- Download the respective country ROM from sammobile for ur phone (SM-950F single sim / SM-950FD dual sim).
- follow the steps in this post (https://forum.xda-developers.com/galaxy-s8/how-to/official-stock-firmware-update-odin-t3598172). (Note: If unlike in the steps, u have a single tar file after extraction of the downloaded file, add it under AP).
- Make sure u have inserted Indian SIM when u start the phone. This is important (it might choose a different country or else based on ur sim - my s7 edge was Italian, not sure how :silly
These steps should not brick ur phone if u do it right. Also Knox wont be tripped. However, i am not responsible if u follow the steps wrong. Tried this method since my S2... Never failed me. Make sure u got pre-requisites right and all should be smooth.
Cheers n good luck.

I did what you suggested. But no luck.

My question is, the Indian variant of Samsung S10e has an Exynos 9 octa 9820 processor and the us variant of it has snapdragon 855. So is there will be a problem in flashing rom...?

Would love to hear back from you regarding this if you had success or not.
I am waiting for my G9750 to arrive in a week and I am wondering if I'd be able to change the csc as I desire.

Does changing the CSC to INS enables the built-in call recording? It's what I'm looking for!

Great.
One more week and I receive my G9750.
Now I only need to find an Indian SIM somewhere here in the Middle East to get my call recording up & running.

On this phone you can't change the CSC. In the firmware there are only 2 CSC's: TGY and CHC (Hongkong and China).

Considering what people have been reporting (that VoLTE & WiFi Calling are working just fine when you configure it using the right SIM card) I would assume that it might work?

Nope.
This is valid only for the G975F model.

VoLTE and WiFi calling would work with Compatible Carriers but CSC won't change as there is no CSC for other regions in the firmware.

it does not work, when you install rom phe it remains btu always

Can you describe it more? What does not work? You tried flashing PHE rom on BTU?

I'll explain myself better so you can understand my problem:
I have an S10 with rom Vodafone Spain, and I want to put the free rom PHE Spain. I downloaded the base to use the Odin installer for pc. Every time I've tried, the CSC goes directly to BTU instead of PHE (Spain). If I reinstall the rom PHE using the CSC home to not lose my data and configuration, it follows then in BTU, just as if I use the non-home CSC that resets the phone. There is no way, I have read that several users have been able to switch to PHE from their S10 plus, but with the normal S10 there is no way. Could you give me some clue as to why? I'm confused, the truth
