I had bought s7 edge G935P , but I am in India , so for LTE bands to work I have been using the G935U firmware and got all the LTE bands, which Jio Carrier supports in India, but It didnt had the VoLTE Option, as I had seen that T Mobile , they support VoLTE, So, I had flashed the latest G935TUVU4APK1 G935T firmware, but this dosent work on Jio sim. But as this dont work, I badly need to switch back to G935U to get the requird LTE bands work as usual and use global mode on U firmware with no bloat of T Mobile . But Later on when I Tried Flashing the U firmware, It always failed, then when I digged into it found that, the installed T Firmware had Latest Bootloader than U and thus I cant flash back to the U, (maybe some efuse lock/trigger issue) . So, I just need to get back to U , is the answer simply NO? or do I need to wait until I get a latest bootloader update for U Fitmware? Or Any other way to get back to the U firmware? Please Help me... I need this BADLY.
Doubt- Can I use the Latest Bootloader of PK1 and flash the U Firmwares PEH1 , AP, CP and CSC ? would that work, or do any help to get back to U firmware?
Which G935U

Which G935U did you flash? I flashed my T-Mobile S7 Edge with G935TUVU4APK1 G935T to G935UUEU4API3 G935U and it flashed just fine.

I need to use VoLTE servie on my s7 edge G35U , but its not the option I am getting easily. I need to use the Jio4G service, but I dont have that option on my G935U (single sim) Global variant. I could have flashed the Indian INS firmware, but the issue is, indian version is Exyons veriant and the U one is running with the snapdragon, also the indian one is a G935FD (dusl sim). So, I cant flah the Indian firmware. So, what are all the avilable options for me to get the VoLTE working on my G935U ?
I have tried the T-Mobile (G935T), Version (G935V) frimware which support VoLTE for US carriers, but it wont work for Jio4G network.
So, the doubt is can I flash the U frimware with the Indian Firmwares CSC and check for the VoLTE support? will the exynos vartiants CSC (G935FD) works on snapdragon (G935U) ones?
Or is there any particular solution for getting VoLTE? Eagerly waiting for a resolution, please help me!.

Hey, I am also struck with the same.. I am using Jio4G service. Why could not you use that? I can help. Coming to the CSC, someone has to modify the 935U firmware CSC with INS/INU, until then we can not use it. I have tried to flash 935FD CSC along with other AP,PD etc of 935U through ODIN but it failed. ( T-Mobile and verizon firmware does not work as they had their respective CSC codes and also 935U has all US CSC codes)

Yes, I am currently using the Jio4GVoice app, but still it's not stable to work flawlessly... also the device is supported but.. without proper software it's not working. So, I hope someone has a solution or any developer could help us with this. What to do?... How to modify the CSC to work with this U device.

Okay. While we awaiting someone's attention - let me run this thought by you.
Firstly, Im new to the android world, firmware, rooting, etc... However with the limited googling done, I wanted to check if this will work.
What if we root our phone and disable/uninstall the RCS application (in my case it would be TMobile) and then that will allow Jio to act as RCS App??

If you are having issues in using the Jio4GVoice Applicatiom. Just install the G935U Firmware so that both data and calls work. Though VoLTE is not there, the Jio4GVoice Application will work and also all bands are unlocked in G935U , you can also select specific bands of Jio. Only thing is VoLTE is missing in G935U , maybe someone can get that feature... hoping for best
I'm pretty sure you need to change CSC to your region. Give that a shot and post back your results. I know the SM-G935U can't flash kernels because it is boot-loader locked, but I'm sure you can flash system and csc via flashfire and odin. So tinker with it see what you come up with.

If you want 935T back again, flash the latest version of the 935T firmware. That's it, but even having the VoLTE on T doesn't help with Jio.
No solutions yet.. I am using jiovoice app for the time being..
You need hyour own carrier CSC file for VoLTE etc. But using your own CSC with the BTU nougat ROM breaks things, and cannot be used. You need to wait for your carrier to update.

It's not possible bro. U can only do this if u have exynos version bought in any country. U,T,A,P,V models have Snapdragon version.
When it is come to Samsung, They maintain regional settings in CSC file which has all these regional settings like volte, APN etc . These CSC file made for exynos won't work on Snapdragon.
I have tried many combinations earlier, flashing snapdragon firmware and Exynos CSC but doesn't workout. I have 935U earlier and tried all these and sold my phone.
We also can't Unlock bootloader for Snapdragon Version and Can't even achieved proper root. SO Volte is not possible.

We can try same on S7.
I have a S7 Edge unlocked TMobile, using it in India. I flashed G935U on G935T, I have lost VoLTE however able to use the phone just fine. Will I be able to flash G935FD os7 (Indian firmware) on my phone and have everything working fine. Or will that cause any problem.. I basically want to be able to use VoLTE and yeah also have the latest os!! Please guide...
We should be able to flash any of the stock firmwares with no issues. As far as VoLTE I'm not sure, you should guinea pig it and report back.

I am using SM-G935W8 S7 edge from canada in India right now.
I want to use volte feature on reliance jio on my device. I have tried odin with different firmwares but was not able to flash stock firmware on it.
I want to know whether 935w8 supports VOLTE service or not? And if it does supports, then ehat is the procedure to so.
Please help me out guys. I want volte on my device.
VoLTE will work only if jio networks provides configurations for W8 variants. Better go to Jio office and put on a request. They can only solve your problem.

The G935W8 probably does support VoLTE in Canada, but it won't in other countries due to the lack of an Indian CSC for the W8 variant.

It'd be impossible to get one, because Samsung would never allow it.
You could try exchanging your phone for a G935F/FD and flash the Indian firmware on that to get VoLTE.
Although you'd lose some money, you'd get VoLTE and the ability to get Indian software updates.

Since the EU version of the OnePlus seems to work with Dual SIM.
Can we flash the US version with the EU OxygenOS and be able to get Dual SIM working in the US?

Actually, this is what I did. Using US Version (Model: IN2025) and then was flashing with the EU Oxygen OS Version 10.5.4. After the flash, the update to Oxygen OS 10.5.6.IN11BA automatically was retrieved and installed.
Two things are surprising to me:
- I was expecting that after 10.5.6 upgrade, dual SIM should work, when limiting the network to 2G/3G/4G. However it still shows that the dual-sim function is not working.
- I thought that flashing the US device with EU, would also change the model from IN2025.
What am I missing here?
Thanks & Best.
dont think it works like that
you risk bricking it by cross flashing firmware

I was using this post -- and no issues. :angel:
OnePlus chat support told me that only configuration and software is different between the regional devices, hardware is all the same.
However it also didn't solve what I wanted to achieve - dual-SIM and (at best) also European bands - like n78 ... :crying:
