Trying to decide whether to get G965FD or G9650 to use with T-mobile US. G9650 will have unlockable bootloader for rooting the device, correct? I realize the device is too new and there is no root for Chinese/HK variant yet but it will be there soon if it has unlocked bootloader.
Will flashing T-mobile US CSC give the VoLTE+WiFi calling features while preserving the unlocked bootloader and root?
The only reason I ask is because Exynos S7/S8+ modem download speeds suck on T-mobile US(10Mbps vs 60Mbps on Qualcomm in same location at same time when I tested). And then G9650 may support band71 as G965FD does not for 600MHz LTE on Tmobile.
Bump...
damn, does S9+ SM-G9650 have or not unlocked bootloader ?
would awesome to have 256gb vs low 128gb on S9+ SM-G965F
It has an unlocked bootloader from what others have posted so far. In fact there is first version of TWRP being tested on it looks like. Not sure if we can flash US CSC on it though. Also the modem on it probably is missing band 71 like international Exynos. There won't be many ROMs out for it but at least you can get root, dual SIM and Snapdragon advantage(as mentioned in reviews) I guess....
I think I'm only going to root if there is a way to go back to stock if I want.
I had an LG V20 on Sprint and I rooted it. Which is fine. All worked well and I was able to uninstall LG related crap I did not want. But with that I could not receive Android updates. I wasn't running a custom ROM, I just wanted root to remove LG installed crap.
I've been reading up on firmware options on here but can't figure out a straight answer. I have the hong kong version of the s9 plus 256gb with the snapdragon chip. My question is can you use odin to flash USA firmware to it? Without getting a hard brick.
Like the fully unlocked firmware for us models that isn't tied to carriers. Thanks.

i have the same question...any answer?
I do not know, but it would be great if you would upload your firmware to https://androidfilehost.com
Also, would you please tell me if you are able to use the native call recording functionality that Samsung pushed out in May with your phone
Sorry for no punctuation my keyboard is screwed up for some reason
Thanks Very Much

Based on what I've reviewed this look to be the best option to do so once you confirm the firmware is compatible.

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.
I was not receiving any OTA from my current firmware because I guess I'm not in USA.
therefore, I'm planning to flash a Korea Firmware(snapdragon) on my US unlocked S9+(snapdragon).
Is it possible?
Also I can flash CSC only of other country to my US unlocked device?
Eg. flashing CSC from SM-G965F to my SM-G965U1.
advance thank you for helping!
I have the same question
I'd like to flash my firmware from SM-G965NKSU OKR KTC to SM-G965NU1
I'm in the USA. Amazon cheap refurbished phone, didn't exactly send a US phone, but tech skills should be able to fix that right?
I've used Odin before, but I don't want to brick the phone either.
Hello, I'm newbie and I just want to ask if I can flash another Firmware on my device, I'm currently on PH where s21 being sold here is SM-G991B (CSC: XTC). I want to remove the bloatwares and some samsung apps are still on Korean Language. I'm using an SM-G991N Model with LUC CSC. If possibly, I want to change it to XTC CSC, I already tried using Samkey but it failed. Should I flash the whole firmware SM-G991B on my device? It's same processor as my Korean Variant phone which is Exynos.
Hope anyone can help me. Thank you!
You will trip Knox if you try that.

It there any other way? coz Korean variant updates takes so long. OTA/Smart Switch I still don't receive the latest security updates.
Not as far as I know... Unless you want to use a custom ROM.
