I got an S21+ with CSC of ACR, and I want to flash it to Android 12 with the BTU CSC so that I can get OTA updates. However, the ROM I found is for G996B whereas my device model is G996B/DS. The only difference between these two is that /DS is dual SIM.
Are there any additional precautions/measures I should take?
This is my first time flashing and I'm really paranoid haha. Thanks in advance!
I have confirmed that the answer is yes. G996B firmware is compatible with G996B/DS. Dual SIM functionality still works.

Hi everybody.
I'm from Italy. In Italy we haven't got galaxy s7 in dual sim version, but i need it.
I can buy it outside Europe, through e-commerce. The problem is that the seller doesn't know the precise code of the model, he only knows that is dual sim and sim free. I would to know if there are different models of galaxy s7 duos sim free, and what are the 4g/lte frequency, to understand if it's compatible with italian sim operators.
Thank you.

There are 2 that i know of.
SM-G930FD - This is the "European" model, u can install Single Sim ROM and Dual sim will work ( faster updates from samsung )
SM-G9300 - Chinese / Vietnam version , no Google Play and some Chinese apps .
About bands, read on those 2 pages
Thank you a lot.
We waiting for other utents if they know other versions.
A question: what means "u can install Single Sim ROM and Dual sim will work"? Is it necessary to change ROM to use the telephone?

No, i just did it because mine came with CSC for Nigeria. I choose an rom for XEU ( UK/Ireland Unbranded ) because they receive updates faster then others, and is closer to me then Nigeria ^^
ok, i understand.
Is this procedure invalidate warranty?

Hi there!
I was wondering, I currently have the SM-G930FD (Exynos Duos) and with the announcement that Samsung Pay is coming to Canada soon, I wanted to flash a Canadian firmware onto it. Would a Canadian firmware work on my device? Thanks!
You'd possibly lose the dual sim capability flashing a single sim firmware, as for the firmware working let alone samsung pay is anyones guess, most likely no.

Dual-sim wasn't a big concern to me (didn't even know the phone had it when I ordered), but thank you!
Hi
Anyone trying installing G930FD on G930F. I have an australian Galaxy S7 which I want to flash with Indian G930FD. I want to do this because, I am giving away my mobile to one of my family member in India.
Thanks in Advance
Most 930F and FD firmware is the same package and should work on both devices.

FD are dual SIM ROM. For weird reason, Samsung only released Dual Sim variant only in India.
Firmware is still the same, it just goes by hardware detection. If a second SIM is present the firmware reads it, if not then it doesn't. You can technically make a G930F dual SIM by changing the board and faking a second IMEI.

g930fd to g930f
friends, my g930f changed alone to g930fd after undo root ...
The problem is that the SIM does not work anymore ...
how to get back to g930f?
I bought an unlocked S8+ from a website. It is from Hong Kong, dual SIM, the model number is SM-G9550. I am using it in Australia. Now there are two things that I cannot do with it - VoLTE and Samsung Pay. Also the Android 8.0 upgrade is still unavailable for SM-G9550, which is crazy. All mobile carriers in Australia has pushed Oreo upgrade but I cannot get it.
If anyone can help me with my questions here:
1) Can I flash an Australia firmware to my handset? If it is possible, do I have to root it?
2) If it can be flashed with an Australia firmware, is the dual SIM feature still available? I ask because all phones sold in Australia (except those on website and apparently overseas version as mine) the dual SIM feature is banned/locked because the telecom companies don't want to allow competition, and ACCC (the consumer council) is just a puppet.
3) If it can be flashed with Australia firmware, can I turn the VoLTE on? At the moment, it cannot be turned on as there is no such an option in the Settings.
Thanks in advance!
I'm sorry to tell this, but you simply can't flash anything other than the chinese software on this phone. There are two CSCs available for the g9550 which apparently are CHC (open China) and TGY (Hong Kong) according to updato. Both aren't on Android 8 and I'm not sure if they ever will be.
So:
1) No you can't. Australian providers make their software for the australian model (which is the international) G955F.
2)-
3)-
So to look the truth in its face:
You might be better of selling this phone and buying the international g955F, which is compatible with australian firmware. alternatively there is the G955FD, which is dual sim, but (i just googled for 2 minutes so could be wrong) there also is no official australian firmware. What you can do with the g955F/FD is rooting, which could perhaps give you the possibility to flash an australian CSC to the FD, if you really are thinking about buying one, someone could sure give you the answer to if its possible or not
is possible to flash single sim firmware to the dual model? i never us a second sim.
