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.

Do you mean the Samsung Smart Switch mobile app? I dont see any option that says 'Emergency Software Recovery'

Note 3 N9005 LTE 4G Doesn't Work, Do I need CSC change?

I've searched the forums and no one seems to have an exact FIX for my issue. So I have a Galaxy Note 3 N9005 32GB black version, the phone works well in 3G, never had an issue with it but now my network provider recently upgraded their plan and offers 4G internet but my phone doesn't want to connect. The provider offers 4G through BAND 1 2100MHz and Note 3 N9005 does have that band but it doesn't want to connect. It only works on 3G and when I enable Mobile Data it says H+! Not once has it connected to 4G!
I wanna mention that my friend has the exact same N9005 phone and his phone works on 4G all the time. Both of us have the same contract with the same network provider!
The only difference between our phones is the CSC region, we have different CSC. MY SIM card works in 4G on his Note 3 and his sim card doesn't work on 4G on my phone. (we exchanged the SIM cards for testing). So the problem is from my phone not from the SIM card. My phone is also original, its not a Chinese clone! Its confirmed with "Samsung Phone Info" app from Play Store.
Here's a few things I already did that some of you may be inclined to recommend to me:
1 - My APN is correctly set
2 - I am on official stock Android Lollipop 5.0 latest version and the phone is not rooted
3 - I already did a factory reset + wipe cache partition
4 - I saw others suggesting that people may not be in the range of a 4G tower! Not the case! Like I said, I switched the SIM cards with my friend on a public bench, out in the open, not even behind walls. Of course and his phone connects to 4G with his SIM card and also with MY SIM card while my phone doesn't connect to 4G with neither of these SIM cards.
5 - In Mobile Networks > Network Mode, my phone is of course already set on 4G/3G/2G (auto connect) and by the way, my friend's Note 3 says LTE/WCDMA/GSM (auto connect) instead of 4G/3G/2G with the same language set on both phones. Why?? I know its the same thing and I know 4G stands for LTE and 3G for WCDMA but why does it appear differently on these phones?
6 - I already went to Service Mode via *#0011# and manually selected BAND 1 LTE, it says "no service" or "emergency calls only" if I do that so I switched back to "Automatic"
So what the heck is going on? This phone is giving me headaches! I'm close to smashing my phone! After this I sweared to my self this is the last Samsung phone I ever buy. Probably I will be switching to Asus or Lenovo in the future. Or any other phone that does NOT have this CSC BS! This CSC thing is a complete rip-off!
Im thinking that the problem could be my CSC perhaps?? My friend's Note 3 N9005 has a COA CSC (Cosmote Romania) and I have a XEF CSC (Unbranded France). Both phones are factory unlocked and work in all networks. They are not branded by any phone maker! His COA CSC is unbranded. Yes it belongs to a phone retailer but that retailer doesn't brand their phones, no bloatware, no SIM lock. If you buy a phone from Cosmote (with COA CSC) it works in all networks, unlike Vodafone or Orange who lock their phones and brand them.
What should I do? Should I attempt to change my CSC? If so, how? My phone warranty has expired a long time ago, so I shouldn't care that much about triggering Knox though not triggering it would be preferred.
Which path should I pursue? Should I simply use ODIN and flash a STOCK COA CSC (Cosmote Romania) or STOCK ROM CSC (Unbranded Romania) from SamMobile.com with the latest version of Lollipop? Would this trigger Knox? Will it affect my all networks unlocked status? I mean, I won't have to unlock it after that, right???
OR should I ROOT my phone, change CSC, then UNROOT? If so do you know of any method to root Lollipop 5.0 without triggering Knox?
What do you guys think? Whats the problem with my phone? Why doesn't it work on 4G? Because of CSC? Or is it something else?
Thanks!

The best way to confirm the model # would be to boot into Odin mode and look there.

What do you mean? Can you be more specific? I already told you my model number, its N9005!! Do you want a screenshot?

Dear OP, have you tried the other Samsung secret code? *#2263# then program it to accept LTE only.
That's the only foolproof way to get the Note to connect to LTE. In my country I only get 2-3 of the 5 LTE bars, so the Note wouldn't automatically connect to LTE or immediately stoop down to 3G through the settings. That specific secret code and setting is LITERALLY THE ONLY WAY TO GET MY NOTE 3 TO CONNECT TO LTE IN MY EXPERIENCE.
If that still doesn't get your phone to run LTE, either your carrier is whack or your phone is, and no amount of Cyanogenmod can fix it because your hardware modem inside the phone might be whack and you can't really do anything if that's the case...

I have already explained that there is nothing wrong with my carrier because I switched my SIM card with my friend's phone who has exactly the same N9005 model and it perfectly works on 4G on his phone. The only difference I could find in our phones is the CSC.
As for the other suggestion you sent me, I already said that I've been to SERVICE MODE. The code you've given me does nothing on my phone but as I can see from your screenshots, it gets you to SERVICE MODE. I've already been there through *#0011# switched to LTE/GSM only or LTE/WCMA only and I've explained that it still doesn't do anything.
Can someone please answer me this? Would it help if I change the CSC? Could this be the problem I'm having???

It may help if your CSC is changed it can do no harm .

Booting into download mode will confirm the model #. Looking under the ROM's settings is not guaranteed to display the proper model #.
Both phones are running the same ROM, bootloader, and modem?

Yes confirmed, same model, same baseband, same everything. The only thing different is the CSC. So whats next?

Did you try changing the csc by dialling *#272*enter IMEI#? Not sure if this method will work for your model of note 3.

No I haven't I'm trying now. Wow if this works Im gonna buy you a beer!

It doesn't work! just my luck! I entered this code: *#272*IMEI-number# and pressed call button, it says "Connection problem or invalid MMI code."

I just tried it on my Note 2 and S4 and it works. Maybe the phone is not running a multi-csc stock ROM?
I don't have a note 3 to try.

Perhaps the code you gave me only works on older version of Android such as KitKat or whatever you have on Note 2... anyway Im using Samsung Phone Info app from Play Store and my CSC is XEF and under Available CSC Codes there is a bunch of CSC codes. Here I've made a sccreenshot:
From as far as I know there are only 2 ways to change the CSC: root or flash a different stock ROM

Yes, the note 2 has kit kat but the s4 is running stock lollipop.

Well unfortunately the code doesn't work on my phone. Anyway if you know for a fact, could you tell me this? Is it safe to reflash another STOCK rom from sammobile? Will it affect my phone in any way?
Thanks

Yes, it is safe to flash stock ROMs from sammobile.com.

I just flashed a local stock ROM and guess what, when I go to Phone Info app it still shows the same CSC! I still have XEF CSC, how can this be? Why hasn't the CSC change?

After flashing the stock rom, did you try the csc code I mentioned? Same thing happens when I flash a Rogers carrier rom over a Telus carrier rom. Once I select telus as the carrier from the csc menu, the Rogers app will disappear and the Telus app appears.

Ok after further researching I found a lot of interesting stuff so I'm gonna write it all down for other people who may need it in the future.
1 - If you have a multi-CSC phone and you flash a different CSC but which is in your "Available CSC" list but which you cannot choose or change without root, your CSC will NOT change. For example: I have flashed ROM CSC (Open Romania) on my XEF CSC (Open France) and guess what after the flash was successful and all, the CSC didn't change! It was still on XEF because ROM was in my "available list".
2 - If you try to flash a different CSC which is NOT in your list, then Odin will FAIL and softly brick your phone. For example: I got my phone bricked, trying to flash 2 CSCs which are not in my "available list": COA (Cosmote Romania) and DBT (Open Germany). In order to fix this issue all you have to do is to reflash YOUR OWN CSC, in my case it was XEF. Or you can even flash one of those CSC which are "available" or compatible so to say, such as "ROM" for example.
This is the firmware I currently have on my phone:
http://www.sammobile.com/firmwares/download/61565/N9005XXUGBOK6_N9005OXXGBOJ2_XEF/
These are the two firmwares I tried to flash on my phone, hoping to replace XEF with:
http://www.sammobile.com/firmwares/download/63441/N9005XXUGBOK6_N9005COAGBOK1_COA/
http://www.sammobile.com/firmwares/download/61464/N9005XXUGBOK6_N9005DBTGBOI1_DBT/
BOTH FAILED in Odin!
There are ONLY 2 ways to change the CSC on newer Samsung phones. Most guides online are based on KitKat 4.4 or older guides but for 5.0 Lollipop or even NEWER there are ONLY 2 ways to change your CSC:
1 - Root your phone and change the CSC. There are plenty of guides on how to do that online.
2 - You can avoid rooting your phone and use Odin instead, BUT accompanied by your stock firmware, you will also have to find and use a PIT file because Samsung as of 5.0 Lollipop uses different partitions for all the different regions. HOWEVER messing with PIT files is super risky and it can permanently brick your phone so its just better to root your phone instead! Dont waste your time trying to flash different regions/csc which is not in your available csc list, it won't work!
What can I say? Samsung is trying hard to block their users from changing their CSC... Why? They prefer their users buy new phones. Its pure greed yes but its what it is... For me, this was the last Samsung phone I ever buy. Im truly disappointed.

Can't find the same version

Hello
My girlfriend and i both have an s7 edge. She has a different stock rom then there is on my phone. We have both the same provider (proximus).
She already has the option 4glte to make calls.
I would like that option to so i'm trying to find her rom to flash it on my phone. The problem is i can't find it on the internet. Not even on sammobile.
The baseband version of her phone is G935FXXU1BPHJ and the buildno is MMB29K.G935FXXS1BPK1.
Can someone find this and please post a link here?
I already put her simcard into my phone , still no 4glte.

I kind of disagree with this statement. my 935f came from the Philippines with csc tpa and now my phone is running Italy firmware with csc itv. so u can change firmware.i use sammobile.com to find firmware but I think their is another website u can use to find firmware but I do not know what it is. download phone info from the Google play store to your girls phone and it will tell u everything about her phone.

So i've searched on sammobile for her stock rom and flashed it on my phone. Now if i go to the app phone info i can see now the following :
product code : SM-G935FZDAVD2
firmware code : VD2
Active csc code : VD2
Availeble CSC Codes : ATL, AVF,CNX,CYV,MOB,MTL,OMN,PRO,SIM,SWC,TCL,VD2,VDC,VDF,VDH,VDI,VGR,VIP,VOD,XFV
CSC COUNTRY : Germany / DE
mobile operator : proximus / 20601
bootloader version : G935FXXS1BPK1
pda version : G935FXXS1BPK1
csc version : G935FVFG1BPH1
baseband version : G935FXXU1BPHJ
And on her phone i see this :
product code : SM-G935FZKAPRO
firmware code : PRO
Active csc code : PRO
Availeble CSC Codes : ATL, AVF,CNX,CYV,MOB,MTL,OMN,PRO,SIM,SWC,TCL,VD2,VDC,VDF,VDH,VDI,VGR,VIP,VOD,XFV
CSC COUNTRY : Belgium / BE
mobile operator : 20601
bootloader version : G935FXXS1BPK1
pda version : G935FXXS1BPK1
csc version : G935FVFG1BPH1
baseband version : G935FXXU1BPHJ
So it's now only the product code , the firmware csc code , the active csc code , csc country and mobile operator that are wrong. The rest is now all the same.
Can i set the active csc code also to PRO? And without rooting? And will the volte work than ? Or are there some other steps i need to do?

yes, switch the csc to pro and then make sure your phone is registered with your provider and it should work.

This is my first international phone because I wanted the latest Samsung phone and have the ability to root.I live in the US. So I am still learning about the different firmwares and csc code.

That's my problem. I can't seem to find out on how to change it to pro.

You'll need to root, then use the Phone Info app which has a built-in CSC changer which can change it to PRO, however keep in mind the rooting will void your warranty and the change of CSC will reset your device to factory settings.

Is it not possible to do it without root?

Sm-g935fzbuxsg cant find dis stock rom helpp
Hello ive tried to root my s7 edge and successfully works, and for some reason, i turned off the oem unlock in dev options. The time comes when my phone got empty, so i quickly tried to charge it but it stuck on s7 edge logo and has a red font above saying "custom binary block by frp lock" i managed to get through it by flashing stock rom from sammobile but on the first boot, my s7 edge was so laggy and cant even make a simple home button it takes so much time for keys to function and there are popping up errors "com.sec.epdg has stopped" and " IMS Service has stopped" and in notifications bar saying "upgrading android/updating android" something like that. luckily i be able to turn it off and go for factory data reset. but after setting the phone, my settings got messed up like theres 2 application, 2 device maintenance and and other additional settings like t roaming,service provider which i dont see on my settings before it all messed up. I also realize that i cant find the fast charging settings which explains why its not so fast when i do charging. Can anyone please help me? You think i flash the wrong stock rom? My original product code is SM-G935FZBUXSG and i cant seem to find it in sammobile. sorry for my english but any help would be so much appreciated.
Btw, my phone was bought from UAE and im pretty sure that my model number is SM-G935FD. My phone is dual sim.However, when i chose the SM-G935FD category in sammobile, i noticed that there were no UAE country, so i choose to download the stock rom coming from vietnam because at the box of the phone it says manufactured in vietnam so i think thats what pushed me to download it. please help

Changing CSC whilist updating to Nougat

Hey Guys !
So, my phones CSC code is DDE which means Deutsche Telekom. Currently Im using Slovak O2 SIM card so i don't think its carrier locked.
Now, I would like to change my CSC to BTU because theres 0 chance Telekom will update their firmware in this century.
So the question is, can this brick my phone if something goes wrong ? I heard stories about deleting IMEI by changing CSC etc.

Download and install Phone INFO from Playstore. Check under the CSC CODE tab which country service codes are available for your specific model. Reference that with Sammobile and download the latest firmware.
(Continue ONLY if you've confirmed you have multi CSC on your device in other words more than one CSC to change to)
You'll notice there are 2 CSC files in the zip downloaded from Sammobile. Flash the one that starts with CSC and NOT the one starting with HOME. Your phone will then factory reset so make sure you've backed it up.
Ps!!! Warning!!!
Changing the CSC / product code on your Samsung device may invalidate the warranty. It may also invalidate the Samsung Knox warranty for Samsung devices
that support Samsung Knox. Furthermore, there is no guarantee that flashing the new firmware will work, even when you flash valid firmware.
In many cases, flashing the same firmware a second, or third, time may work.

Nevermind try it. You'll see the magic. But be careful unless your phone is sm-g930f you may brick it.

I hace a similar problem, phone info says my csc its from BTU (UK) but I'm in Peru, I cannot make calls, How can I flash the correct csc for Peru?

How to unbrand S8?

Hey people,
I have recently bought a G950F in a pre-sale from Vivo, which is the carrier I use here in Brazil.
I hate those carrier extras (apps, splash screen and stuff). Every time I buy a carrier branded phone I flash it to get rid of that stuff. That's what I wanna do with my new S8.
I went to Sammobile site and could not find a specific ZTO ROM. So I took notice about multi-CSC ROMs. I was then searching for a multi-CSC ROM which fits my phone, and I found this one: https://samsung-firmware.org/download/Galaxy S8/60y7/UFU/G950FXXU1AQCC/G950FOWT1AQCC/
This is for Uruguay (UFU), but also is exactly the same ROM I have in my S8, and included ZTO. Since it's for a different country/region, I flashed it (using CSC file, not home_CSC), hoping I was debranding. But I was not, my S8 is still branded.
How do I unbrand it? I have read that I must flash a OXM CSC ROM (it also includes ZTO) to change the original CSC of my phone, since it may not have changed because it was the same that it already had. Is that right?
I will try now an Argentina ROM (https://samsung-firmware.org/download/Galaxy S8/98v5/ARO/G950FXXU1AQDG/G950FOXM1AQDG/) which is OXM CSC.

Samsung was pretty strict about what carriers were allowed to install this time, at least in the US. Try to see if you can just uninstall the carrier specific apps, on my phone nothing was in the system partition so they could all just be removed.

Not here in Brazil. I can uninstall some, but not all carrier apps.
What bothers me is the awful splash screen. I can't remove that.

When I had a Galaxy S5 with a 3uk or ee splash screen if I remember correctly there was a oem folder or something similar which got loaded everytime irrespective of what rom you flashed, maybe that's the case with branded s8's?

I don't think so. I had my S7 flashed to debrand it, and that did not happen.
Yesterday I flashed my S8 with that argentinian ROM I have mentioned (https://samsung-firmware.org/downloa...G950FOXM1AQDG/). It looks ok now, without carrier splash screen and bloatware.
But sometimes I get a notification from AutoPreconfig, asking me to use new apps and configurations from my new service provider. If I open the notification, it says that to use apps and configurations from my new provider, I need to restore my phone, all my user data shall be lost, etc. I can press "ok" and nothing happens.
Why does that happen?

How did you get it? I only see SM-G950 available in Brazil.

What i did was this:
1. get you phones imei:
go to dialer > dial *#06#
take a note of your imei without the /01 at the end.
2. go to phone dialer > dial *#272*(your phones imei)#
3. choose which csc you need and install it.
your phone will reinstall firmware with the new csc region you choose.
done.
Just done this to my S8 SM-G950F and switched from GLB(carrier) to XTC(unbranded) csc.
hope this helps.

If you want to disable apps you can purchase Samsung Package Disabler works well to disable apps you don't want.
