The problem in your use case brother is you're running the international phone which has an exynos processor, and the U1 Rom is running on Snapdragon hardware which was issued in the US. Your model won't run the US rom it's for a different hardware.
That being said, why do you want the US rom? What is it that isn't working as you would prefer with your current rom - because there may be a more optimal configuration amongst the many options on that internaional device which you could change your CSC to fairly easily with a couple Samkey credits - that will let you do whatever you're wanting the US ROM to do. I've heard people have been using the Indonesia locale 'cus it has native call record... Perhaps US English set as default language in your device and keyboard + a different CSC will accomplish what youre trying to do anyway. Good luck!

note 5 dual sim language

I don't know anything about morelocal2 and I did not know about the dual SIM firmware I also do not know what language you are looking for. I do know that for the 920I the Australian firmware has more language choices than the Singapore firmware I was on. If you can, I would look for an Australian version of your firmware (I am not even sure if there is one) and flash it using Odin. Be sure the bootloader is the same or newer and that your storage is the same (for the dual they may all be the same) or your flash may fail.
Good luck

Can you flash SM-A716U (T-Mobile US) firmware on the SM-A715F/DS via Odin?

Hi there,
I was wondering if anyone knows whether it is possible to flash the T-Mobile US SM-A716U firmware on the SM-A715F/DS device. Will Odin allow it? Will the device function? As far as I can tell, the chipset is the same, but I wonder how it would affect functions like Dual SIM. (The T-Mobile firmware also has support for 5G, which may not be supported on the SM-A715F/DS.)
Does anyone know what could happen, or if it works? Are there any negative consequences, and could someone explain if the bootloader needs to be unlocked or anything? Ideally, I'd like to get that SM-A716U firmware loaded in the SM-A715, but want to keep everything as stock as possible. I'm also not terribly familiar with Odin., so I'm not sure if the software allows flashing a firmware intended for a different device variant.
Thanks in advance!
no, it won't work. A715F kernel doesn't have property for A716

Change from G7810 to G781B Please help me

Hi, I wonder if it's possible to convert Hong Kong variant of S20 FE 5G (SM-G7810) to European version (SM-G781B). What I have to do?
Please help me!
it is impossible to do
I am interested too, since I bought a SM-G780 model, which will be delivered to me in the next few days and I would like to carry out the same operation, I have already downloaded the Italian CSC ITV firmware SM-G781B; through Odin, can it be done? The phones have the same features, same processor, change the RAM which in the SM-G780 is 8GB, while in the SM-G781B it is 6GB. Thanks.

I also follow, I'm in Italy, in 15 days I'll get the:
SM-G7810 S20 FE 5G 8GB/128GB.
Have you discovered or tried how to put SM-G781B Firmware?
This information will also be useful for other people who will find themselves in our situation in other countries!

do not give people false hope, this method will not work.
I can say that it will work 100%
Voice HD+ (EVS full band 128kbit/s) you only need to correct the configuration a little.
And flash G7810 to G781B - not possible!

I still have to receive the smartphone, I found the difference between the G7810 and G781global on this forum.
So what are the substantial differences then? And is it possible to put a Firmware / Global Rom while keeping the original phone, that is, without root and with OTAs?

I don't understand what you are trying to say.
First you pasted some screenshot without showing second one for global version (for which rom is it?)
Once you say it will work then you say it won't
As to WiFi calling I am using it all the time at home with Chinese version.

Hello, I ask you for more precise information if you can give it to me, since you have this variant!
What are the substantial differences between the G7810 and G781B versions, and the problems with the HK version?

Perfect. While the Google PlayStore, and other services work? There are no problems or report at the software level I mean!
Because for my country Italy, the frequencies of use of the G7810 are fine! So I was more interested in removal or software related problems!
Thanks a lot for the answer
its not posibil to do that and you dont need to do it you will get the update later in february.
Today arrived my 7810. As I need to be avle to use phone-recording I always did the CSC-trick trouwgh the THL-roms on S8, S9, S10 etc.
Therefore I am curious if there is a way to make phone recording work native as described above, or through app as ACR-call recorder on THY ( Hongkong-ROM).
For hardware the difference between 781B ( Global) & 7810 (Hongkong & China) is 6 GB vs 8GB.
That's probably why people think it is possible to flash other ROM into 7810 .

First have you forgotten the fack this is an international forum, where english isnt for a lot of people tghier first language. And secondly being insulting helps no one.
If you can a technical reason as to why the OP can't just flash a G781B stock rom to his G7810 device, that would more productive. Will it for example just not work and soft-brick his device requiring flashing back to G7810 firmware etc..?

Are you sure the OP has an 8GB version, checking the following website shows the spec are identical -

Ofcourse I'm not sure about HIS, but MINE is also a 7810 Hong Kong version with 8 GB.
ALL European sold S20 FE 5G are 6 GB.
So what are the software differences within the sm-g7810 and the sm-g781B because i want to buy this phone too.

I would check GSMarena to start with.
As I do not have a 781B, I have no idea about the differences.
Runing a Chinese ROM for now because of native call recorder.
Works fine in the Netherlands.

I'm thinking of buying the hongkong version from Canada. The process of unlocking the bootloader and rooting will be easier in this version right? Will the custom ROMs be compatible with the 8 GB hongkong version?
Otherwise I will go with the Canadian version.

Firmware and csc question

Hello everyone I live in th u.s. and use my a71 on att. I bought my phone at rent a center and it has buc1 firmware and the csc is TTT (Trinidad and tobago). I would like to install a custom rom because I recently rooted and the smartview feature which I use often isn't working right and none of the fixes are either. My question is this: which firmware should I install to get a clean slate and possibly try a custom rom? Not sure why a phone in the US was sold with Trinidad firmware. I would prefer not to flash the stock ttt firmware if possible is there a better option? Thanks guys
hi friend, I have been almost in same situation (different country) and i would like to share with you my experience maybe it will help if you are still looking. some options / features included in the ROM / OS depend on where the device was sold or aimed to be sold initially by Samsung, for example 2 phones same model, same tech specs, same android version, if one is old in Europe with a certain firmware, it may not have same all options / features as same one sold in US or elsewhere .... i bought a device sold initially in Italy and couldn't find samsung pay or fm radio app in it (even that device does support it from hardware side) and not possible to install it as third-partie app either in anyway possible, and it didnt show up even with a custom ROM .... so i did some dig in and found THAILAND firmware for same android version have it by default + others things i was looking for such as native call recording .... basically long story short, as longer you already rooted it, we can forget about warranty, which should gives you more freedom to install wharever you want ... a custom rom is specially to enhance perf by removing some apps and adding some more features that arents includeed in stock firmware ... but if you are okay with basic stock firmware and all its apps and contenents you don't have to install ncessarry a custom rom ... you can juts look for a specific firmware REGION/COUNTRY that have the option you are looking for and go fo it, like i did from Italy to Thailand (while im living in whole different country of those two), and all will be working fine for you ^^

Question Help to clarify doubts about CSC changing with Samkey

Greetings folks, i have been reading a bit about changing the csc of the phone, I own a s21 Ultra G998B version and its branded with a owo rom, i live in Chile, and the Claro company of course is not up to date with the otas, and also i want to flash a clean rom with no bloatware. I read that with samkey i can change the CSC to an OXO (mine is owo) rom so i can then flash the muti csc rom. I also read that in order for samkey to work i have to roll back to may update? i'm currently on august update. am I correct in the process? can anyone recommend to which csc i can change so i won't turn my phone into a mess
thanks to all who can provide some light jeje

hi, yes it is, but i looked in samfirmware and the cho version is until august, so i think it would be the same? mine is chl which is for CLARO company and is also in august update, i would like september updates so i can try the andy 12 beta
When I bought it, it had May firmware. I changed CSC before any other update .
So , may update is working for SamKey.
Otherwise, you need to flash with latest Odin the may firmware of your CSC you want (downgraded)

No to both. Thailand FW is configured for the Exynos SoC. The China FW, even though it's configured for the Snapdragon SoC it's not compatible with the US Unlocked variant. Do you live in Thailand? If so I'm curious why you aquired a US device. We often see users buying non native devices, maybe they got a good price, maybe they moved out of their region, maybe it's a company issued phone but it's a pain when call features or 5G don't align with your service provider. Flashing non stock firmware often causes more problems than it solves. Samsung is moving closer and closer to proprietary software for individual models, mix and match is becoming a thing of the past.

I live in Kaliningrad, Russia. This device I've bought for 30usd, new, boxed,, here, in Russia, so I was looking for ways to make it work as a Russian device(full menu translation, bands, etc.). Actually no matter, which language is used, at first I had troubles using android 11-there was no esim. Than using abd I flashed it to oneui 4.0, esim works, all lte bands are supported.

$30 USD is an awesome deal! If all bands and esim are functional that's probably as good as it gets. Unfortunately Exynos compatible FW which is dominant in Russia can't be installed on your device. Gboard may be your best option for Russian Language.
