SM-A510Y/DS rom compatability with SM-A510Y

Can anyone tell me whether my dual sim SM-A510Y/DS will be compatible with roms for the single sim SM-A510Y? I am confused becuase under about phone it is listed as simply SM-A510Y.
Its a Taiwanese version and Samsung hasn't released marshmallow for it yet but they have for other regions.
Any input appreciated, thanks!

Samsung Pay Australia

Hello fellow S8 users,
I've recently purchased a Samsung S8 SM-G950FD from eBay as I wanted the Dual SIM capability. Version image attached, I'm not entirely sure where it's from.
Unfortunately the Samsung Pay version on the phone is in Chinese as are the promotion, images attached.
Can someone tell me if it's possible to get the Australian version on Samsung Pay on this phone?
Can I just update the ROM to an Australian version? If so, would I end up losing the Dual SIM capability?
Any help on this would be much appreciated.
Thank you.

Any suggestions?

Your Australia cards should work as Australia already have support for Samsung Pay. I have setup few of my Indian cards with Australian version phone. I guess you need to bear with the Chinese though. Updating XSA room will definitely disable the Dual sim option and I am not sure 950FD support 950F.

Yeh the Samsung Pay Application doesn't like my American Express Card....
It states that Amex is not supported in my country, but in fact it's working on my Samsung S6, and my Gear 3.
So you think changing the firmware to AU I would lose the Dual SIM capabilities?
It might just be easier to try and get the Samsung Pay and Samsung Pay Framework from AU ROM and extract it to mine maybe?

If it's anything like the S7, you should be fine putting the Australian firmware on it. I got an S7 edge from the UAE and had to flash German firmware and the T-Mobile CSC to it for spay to finally work. It'll be trail and error, but the multi sim function never went away for me.

Since almost all the international S8/S8+s are on the multi CSC ROM, all you need to do is reset your phone (preferably from the recovery menu) and put in the Oz SIM and reboot. All the regional features are activated, and you get Oz SPAY.
Using that method, I am currently using the India SPAY on an Afghanistan S8+ (Dual sim) and Taiwanese S8 and both work with all cards.

I've actually tried to restore to factory setting 6+ times with an assortment of sim cards from Vodafone, Optus, Telstra, Macquarie (Telstra variant), samsung pay keeps loading up as Taiwanese version (Chinese)...
I've recently asked a friend to extract his Samsung Pay & Framework.apk, it still loads Taiwan Samsung pay.
I think it's region locked?
I'm going to try and restore to XSA Firmware, apparently this worked for the S7 guys, whilst retaining Dual Sim functions.

Did you try to factory reset from recovery? Vol up + Bixby + power, wait for few seconds it goes into recovery. Put the regional SIM in, then reboot. It will reboot twice and activate SIM specific features (prominently tells you that it's doing so).
Also please post a screenshot of the Settings->Software information screen (Service provide SW ver. is 2nd last row) both before and after you complete the process.

Someone recommended me this solution after I had a similar problem with my UAE S8 and flashing other country firmware no longer works without supporting SIM card. Download Samsung Pay version 2.7.03 and try that.

Means that it doesn't matter which firmware you flash if you don't have the country's sim card because s8 will default back to factory CSC. Only way to change CSC without root is to flash with the supporting sim card installed.

Has anyone here got the Australian Samsung Pay app onto the Taiwanese dual-sim model? I purchased an S8+ at $799 (compared to the RRP of $1349) but I don't want to factory reset if I don't have to.

Anyone got spay working? Pkease share what firmware version are you using.

XZP VoLTE firmware

Hi Guys,
I'm almost happy user of XPZ. I bought non-branded version G1842 dual. I want to use VoLTE(and WiFiCalling if possible) on my handset. My operator Orange PL supporting VoLTE but only on Iphones and branded firmwares for Android phones.
Sony support/service refuse to flash my phone with Orange firmware - so I would need to do this alone but official Orange firmware is available only for single sim XPZ G8141.
Question - can I seftly flash G8142 with G8141 firmware? Or do you know that maybe VoLTE operator configuration is kept in one of sin files like modem_X-FLASH-ALL-42E5.sin and I could just swap one file in whole firmware folder?
Secondly VoLTE - I send email to operator and they replay that configuration of VoLTE is many settings/parameters inside firmware. Besides *#*#4636#*#* option VoLTE provisioning I didn't see any configuration for this service. The config is so deeply inside firmware? When I switch ON this option in that menu it's not saved and when I enter once again the menu is one again switched off.
What I saw most of the VoLTE arround globe have problem - that they need to use branded firmware. Do you think in the future it would change? As far as I check for Iphone it works on all - it's relevant it's branded or non-branded phone.
best regards,
Piotr

I'm in Sweden and VoLTE got enabled for me when I switched carrier. I didn't do anything but switch SIM. I had a Z5 Premium at the time and now I'm on a XZ Premium and VoLTE is enabled as default.
And standard Nordic Combined firmware, no carrier lock.

Piotr, i think with DS version of device you are out of luck. There is no european provider specific modem configuration(required for volte) available for the dual sim device. I have attached available configurations in the zip file.
To get single sim modem configuration files flashed to device, you need to flash system.sin, but i STRONGLY DO NOT recommend doing that. Potential brick on your way.
Mixing flashing the single sim and dual sim different .sin files is highly experimental.
If you really want VoLTE then i think less headache is if you can find a person who is willing to switch single sim version with you.
You can get any region G8141 and then flash https://xpericheck.com/cda/1308-7002
Phone needs load configuration amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn to get VoLTE and VoWIFI.
Checking current oem.sin file, i can see that when inserting Orange PL sim, then amss_fsg_maple_orange_poland_ims_tar.mbn is actually loaded.
Is the XZ Premium on confirmed VoLTE devices list on Orange Poland webpage?

Hello, any news in this thread? I have the same situation but with XZ1. I have nonbranding dual sim working on T-Mobile PL. They sell XZ1 only single sim, so there is only single SIM firmware from T-Mobile. Someone test flashing single SIM firmware for dual SIM XZ/XZ1 Xperia?

Should be same situation as with xz premium. flash single sim fw via newflasher and you are done. will lose 2nd sim but otherwise should be good.
Please Read different topics to know how other users have done it to xz premium dual sim.

Are dual sim variants of xz1 and xzp installed with the required 4x4mimo hardware antennas?

Just flashed XZ1 DUAL with XZ1 SINGLE firmware. Everything work at this time fine and VoLTE and VoWIFI are working from the start!

In system information stay now G8341, and naturally i lost second SIM in menu.

Why dual sim are sold cheaper then singlesim? Which country?
I bought XZP in presale and price for non-brand and brand at telcos was the same. For me I was thinking it's benefit because I get dual sim and "clean" FW.
I suppose that Sony (and also Samsung) don't care about this....I hope that carrier services app in android recently added by Google would be the way to update settings for operators for all headsets. Like apple does. That would solve that configuration....
Only when small file missing and and lot of issues with VoLTE and VoWiFi.

Maybe single and dual sim are exactly the same HW? and when you load DS FW into SS version you will get DS? anyway 2sim share slot with SD ...maybe Sony simply manufacturing process?

To confirm files like amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn are kept in which file? oem_X-FLASH-ALL-42E5.sin or modem_X-FLASH-ALL-42E5.sin ?
This file are modem configuration so it should be more in modem.sin but you mention that you check oem.sin for that maple config?
Is 100% configuration of VoLTE are kept in amss_fsg_maple_orange_poland_volte_vowifi_tar.mbn ?
In 20 minutes I would also try to flash XZP like rav.6 with XZ1 to check that solution. And let all know.

oem.sin only includes instructions which configuration(.mbn) to load.
all configuration are universally available in system.sin

In T-Mobile I have activated VoLTE and VoWIFI by sending message to T-Mobile. I don't know how it looks in Orange, but i think you must activate it first.

Very confused with where my phone is from and what updates it can get

Hi,
My apologies if this is an obvious question but I'm a new Galaxy S8 user and I've gone through these forums extensively before giving up and making this post
I had someone bring along a Samsung Galaxy S8 from the US to India, and it seems to be working like charm. They ordered it online and picked up the unlocked international variant (SM-G950F)
In the Service Provider Software I see 'INS/INS/TPA'. I assume INS/INS was set because I popped in an Indian sim. TPA seems to be Panama?
Now I check my software updates and I'm stuck on the May Security Patch and there really aren't any updates for this firmware.
I want to switch to an Indian firmware but on updato and sammobile, only the SM-950FD is available for India as only the dual sim variant is sold in India
I want to flash a firmware with the latest update and also receive future OTA updates but I'm not sure which firmware to flash.
Is there no solution for me?

i can tell you only this: had bought a Dual Sim S8 in Germany, the phone was originaly from Egypt. (DBT/DBT/EGY), and received OTA's.
*but the battery life was horible

Install Phone info app from google play and open the app it will show you all hardware and software information of your phone. See the CSC code and find your software according to your region.

You can flash FD firmware, it is the same.

You have dual sim model G950FD or single sim G950F
check hardware to remove sim and card socket and see the card socket is hybrid or not.

It doesn't matter what FW you install, you can never change it to INS as TPA is hardwired to your phone.

It should change to INS/INS/TPA. People commenting should understand that F/FD doesn't matter, as the software is the same. It's discussed here MANY times.
EDIT: last csc being TPA doesn't matter

Please check your back panel of your phone. The model no. Is written over there. If you want to update your phone to latest firmware its so easy. Find your model no. Is F/ FD download any firmware of any region you like and flash through Odin. Flash all 4 files with home csc.
I think your main issue is latest firmware not csc because your phone is Sim unlocked. You can use any sim card of any country in your phone.

Oneplus 8 Pro Dual SIM

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.

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:
