Is there any way to bypass the region specific features such as rhe blockchain keystore so it works in america. Like flashing a different software version for a different model? To allow the phone to let me use the blockchain keystore?

IDK about blockchain keystore, but your device has an Exynos processor. US devices are snapdragon variants.
So flashing the firmware of the US devices won't work on your device.

Hi. I want to flash a Brazilian firmware (dual SIM) into my US hardware (single SIM). Both are Snapdragon. Reason is that I want to use the Brazilian Samsung Pay. Bough the phone in the US but I live in Brazil.
Can I flash THIS ROM without problems? Will it trigger Knox? Any loss in functionality?
Thank you all.

not possible. also, is there not a CSC for your area you can flash instead?
I don't know why these guys say it's not possible, maybe it isn't with your model. I also don't want to give you any bad ideas or anything, so use your own discretion & research.
My phone was unusable when I did this, so I had nothing to lose when I did this (It worked though).
I easily flashed my canadian note 8 with a us firmware using modified odin (must be same version bootloader).
It has warranty status 0x0 (aka, Knox is NOT tripped).
AGAIN, I'm not advising you try this with your model, unless you know what you're doing. I just want to make the information available to you.
Edit: I'm just waiting for someone to upload snapdragon beta 3 one ui 2.0. I'm going to try the same method to convert my Canadian s9+ to USA version.
Edit 2: I can confirm this method works on my Canadian s9+ aswell.

Yeah I don't think it'll work on mine, since it's a single sim phone, and the ROM I wanted was for a dual sim version. Unless of course the hardware is the same and the second SIM slot is present. I could try, but I don't want to risk it. Maybe later when Sammy stops updating the phone.

Unfortunately not. The SM-G965U1 is the US unlocked version. There are only CSCs for American carriers.

if its truly unlocked, then you should already have the U1 firmware on it. Get modded Odin and the U1 firmware, flash it in Odin and go from there. I never looked back after ditching the carrier junk on my phone
Sometime ago I did somethinh like that on my Arabian S7 Edge that I bough in Paraguai, it was Dual Sim model and i flashed ZTO CSC via Odin, and the phone was working well, but i'm not sure if the reverse works, and even the models were similar (F vs FD version) in your case u have 965U vs 9650, I would not take that risk, i thing that a korean or chinese model is 9650 too
look at this picture, US version has more bands so the modem could be different, you can try but you're risking your phone

yep, they are different phones that just so happen to use the same processor. Different bootloader, same chassis for whatever reason. Anyways, there have been threads talking about converting the 9650 to a 965u, but ive never seen anyone confirming that it indeed works. Big risk, but as long as one can get back to Odin mode, one should be good.
Has anyone tried changin the chinese version xqbc72 firmware and able to enable the modem freqs for here in the US?
basically changing the chinese to a US model with 5g enabled.
My understanding is that it is not just software that enables carrier bands, but it is also a hardware limitation along with the proper firmware. If possible I would recommend you stick with a US version for the US...besides you may need the warranty.
I have a S23U(S918B/DS) in China, but there is only 4G can be used. Flashing a third party SoulRom based on Mainland China version can use 5G, but I don't want to root my phone. Can I just Odin flash the Chinese version baseband instead of the whole firmware? The 5G Specs of 918B covers all the 5G bands in China, is there any service code to unlock the SA/NSA mode or more 5G bands in hidden menu?( I've tried S918U service code but it doesn't work for S918B)
Many thanks!
Have you tried the samfw tool method?
Does trying to dial below do anything?

Then check the band csc changing thread. You may need to flash the US firmware, then enable secret codes then enable all bands. You might then be able to flash back, if you want, and all the bands may remain open.
5g overrated anyways. Lte is better.

Change your CSC to ILO or INS, let us know how it works out for you.

Did you have any luck with this? I travel between China and the US a lot, and I am wondering if I can get 5G in both countries with the S918B/DS on Verizon & China Mobile.
I just bought US model of s23ultra, but I actually live in Taiwan
the issue is none of it's the carrier aggregation is supported here
so I wonder if it is possible to flash SM-S9180's firmware on SM-S918U1 device ??
if it can:
1. Can I get future update by OTA??
2. Will it break Knox??
if it can't, is there any other alternative way to change the the carrier aggregation setting ??

Don't do it. You will brick device.
You can't flash U or U1 phones to B models it will brick your phone.
To enable carrier aggregation, check this thread

Cool. Ok. I never got luck with that
Hello . I have a question about the Galaxy S23 ultra from 2023 all models are equipped with snapdragon 888 gen 2 before in B model Samsung use their exynos chip so what's the best deal the main difference now between U model And B , can we change our U model csc to like B to enable call recording, can we flash B model firmware on it ?
The biggest difference is that u and u1 models can never be oem unlocked because samsung completely removed that option from the software. The other models can be oem unlocked.
Without oem unlock root and BL unlock is just not possible.
As for csc changes, I've tried to change my u1 csc to a B csc and it just won't do it. As for call recording I can't get native to work on the u1 but I have the app called skvalex call recorder and it works on my S23U

Your comment seems to suggest it is Samsung's choice to remove that option, while I understand it is merely a locally imposed requirement (providers? authorities?)

It's not local or providers because other devices sold here can be oem unlocked same as the carriers here allow oem unlocks on devices. Just not samsung. I've been told it's Qualcomm that makes samsung do this but why would they just do it to samsung because Qualcomm supplies components for other manufacturers that sell here yet they can be oem unlocked. The way I see it, it's just a way for samsung to prevent using any other roms on their devices in the US.
My question is why we cannot flash B firmware on it and does U model also has dual sim hardware like B and E model

No dual physical sim but there's 1 sim and esim but you can try to flash the B firmware but it gives an error. I'm willing to bet that even if you could force the flash that it wouldn't boot because samsung would probably make it a brick on purpose for anyone who tried to force it.
I had Galaxy s21 Fe snapdragon model single sim no esim and I converted it to dual sim a physical dual sim device
Both have physically different antenna/modems in them.

Wow, I haven't had Samsung since S3 but was looking at the ultra; and seen unlocked on Amazon(referring to network I suppose), I'm sure thankful to see this info. I was thinking about getting the international version for T-Mobile in US? Thanks for suggesting, advice, etc.
