Sim vs dual sim rom support - Samsung Galaxy S9 Questions & Answers

Hi people,
I'm going to get a used Exynos S9 soon and I'm wondering if it's better to get the single sim version for custom rom support. I know that the S7 could be flashed both ways so it would be the same, does this hold for the S9?
Cheers
Teddy

I have the same question. Can someone answer? I see that in many rom threads they don't refer if the model is single or dual sim. So I guess they work in both? Thanks

I'm sure the ROMS work for both variants, it may say in the OP of the ROM you want.

N930F or N930FD ?

Hi, i was just wondering if it would be a difference, talking ROMs field, if i buy a n930fd or a n930f.
Im a freak rom flasher and i always see problems with compatibility with dual sim devices, ill use a single sim and a microsd but i dont know if the roms compatibility is an issue of the fd firmware even if u use 1 sim card or is a problem that appears only when u use 2 sims.
Im tired of waiting the n930f version to come out and i would like to buy the dual sim version but it will be a no no if ill have lack of roms or more issues even using 1 sim.
Tnx in advance.
U want custom roms? Dont buy a dual sim.
I too was faced with this dilemma.
they're identical in every way except it supports 2 Sims. there's really no reason for the inferior F model to exist with FD around.
and yes you can flash custom roms fine, the same roms as the F gets. I've already flashed a custom rom to my FD phone.
the only hardware different is the Sim card tray.
When you flash an F ROM to the FD do you lose the Daul SIM capabilities?

simple doubt about HTC M8 dual sim rom

hi folks,
i have a htc m8 dual sim, and was wondering if i can flash a custom rom for the htc m8 standard model? i will lose the 2nd sim functionality, or brik the device?
thanks!!!
It won't work, the hardware is different, therefore different ROMs. Not certain if brick is a consequence (of flashing wrong ROM). But it's possible.
S. ROM supports both "regular" M8, and the dual SIM. But the ROM thread specifically states this. And this is the only ROM I know of, that supports both variants. Otherwise, you need to tread carefully, and only flash ROMs specifically for dual SIM.
Further, the dual SIM is different from the M8s variant (which is the forum section you posted in). So don't let that confuse you, either.
thanks for clarifying that. i supposed it, but wanted to be sure.
and sorry for posting in the wrong section!

Need basic info on CSC codes (please help me understand them correctly)

Ok so I really y need your help guys!
I've asked this question a few times in the past about other phones I ended up not keeping, but I'm now intent on making this work.
I'll keep it simple: can I flash a Canadian CSC on a Global phone? Will this brick the phone?
I don't quite fully understand how the CSC relates to everything else, but the times I tried I couldn't get the CSC to change. Plus I'm concerned because I have a dual sim model (which doesn't exist in Canada) that is Exynos, where the Canadian model is a SD.
Through my reading I think it could work but I don't want to have a $1000 paperweight in the end, but I'm have piss-poor reception, Samsung Pay doesn't work, VoLTE doesn't work, I can't block phrases in SMS and the list goes on. I want to try this to see if it helps anything... Failing this I may cut my losses, sell the phone half-price and just get a non-Samsung device; I'm getting so aggravated at this it's not even funny.
Thanks!
PS: if you are wondering why I didn't buy a Canadian phone to start with, let's say it's a complicated answer but can be summed up by the dual SIM cards.
A CSC defines that carrier settings of the phone. As long as you use official Samsung firmware and do it properly it will not brick your phone. Look at sammobile first to see if Canada has a stock firmware. However, doing this will mean all data is lost, are you flashing carrier based firmware or your country's global software?
I just did a search and on the S8 there was no difference between the single sim and dual sim softwares and on GSM arena it classes them as the same. Do you the have snapdragon or exynos version?

I don't mind data loss, I have back ups and really not much on the phone anyway. Canada has stock firmwares for each carrier, so to answer your question, carrier based. But my huge deal here is the different configuration between what is available here and what I have: I surely can't flash the entire firmware based on a canadian phone... I would lose my dual SIM and surely the difference processors would brick the device. But I'm not really sure if I can mix and match, i.e. pick a CSC for my carrier and everything else (PDA), and if I can, what do I chose?!
See where I'm at... because I can't flash the entire firmware I think I'm s.o.l.
I'm afraid the situation isn't that good for you.... I am assuming you have the Exynos varient since I cant see a dual sim version of the snapdragon variation which means no Canadian firmware is available for your device at all. Since I'm in the United Kingdom we usually swap our CSCs with ease but it appears if you didn't buy the snapdragon version your out of luck at least for now. I'm sorry I couldn't be of more help you could sell and get the Canadian version but you won't be able to dual sim or get another phone I left from the S6 to oneplus and had a really good exprenice but that was on the 3T so I'm not sure what they are like now
Again sorry I couldn't have been more help:crying:

H4233 and TWRP/root/ROMS

Morning, everyone.
I'm in Japan and just got the X2 H4233 variant. Seems like AOSP isn't supported for this variant (I looked all over Akihabara for an American or international phone, but to no avail.) anyhow, what are my options for rooting and ROMS? I'd really like plain old Android.
Thanks!
You should try the AOSP made for H3113, many people reported that also worked for other variants as H3123
Thanks! I just checked out the thread and it might not work. H4233 is a dual sim model, so I may have to wait until someone builds one for this variant or at least one with dual sim.
On the bright side, I learned that I can unlock the bootloader, so I should be able to root it. However, I'm still not even sure if I can install TWRP.
Also you can ask in the forum if someone else tried with the same variant that you have
https://forum.xda-developers.com/xa2-ultra/help/unlocking-bootloader-rooting-t3762968/page20
In this forum, you can read that the TWRP for XA2 works on the XA2 Ultra, probably will in your variant and also there are instructions how to root your phone
Seems someone recently tried it and it works. That's one step closer!
Oops. Double post.

[Q] Differences between G960F and G960F/DS

Hello dear friends,
I want to buy a Samsung Galaxy S9.
The only model avalaiable available here is the dual sim version(G960F/DS)
The question is...the custom ROM`s that are available for the single sim version(G960F) are compatible with the dual sim version(G960F/DS)?
Yes

Yes

Ok, thank you. I was affraid to buy the dual sim version due the lack of XDA support for that model. But, if the custom ROM`s are compatible, I will buy it.
