S9+ G9650 on T-mobile US for WiFi calling/VoLTE + Root? - Samsung Galaxy S9+ Questions & Answers

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.

Which model to buy for easy rooting?

Hi Everyone,
I have finally decided to get the S6 edge as the prices have fallen within my budget. I want to get an unlocked 64 GB GSM model and root it using pingpong root. Can anyone tell me which variant I should get so that I can root and continue to sideload updates while not losing any features.
Thanks!
I suggest you get the international model SM-G925F.
It is unlocked and has the widest support of the community (I saw kernels only support international models G925F/I for the first few versions, before supporting other variants).
Any idea if I can root it and then update it to the latest firmware (while keeping the root)? Don't need OTA, just any way to do it is fine. I love this phone but it has so many hoops to jump through. I need root for adblocking and also need latest firmware for samsung pay.

FW SM-G965U1 (USA Unlocked) on S9+ SM-G9650 (China Unlocked), is it possible?

Hello, i'm in Italy and i bought S9+ 128GB SM-G9650/DS (China Unlocked Factory) to have Qualcomm Snapdragon CPU.
Can i flash FW SM-G965U1 (USA Unlocked Factory with Snapdragon also) with Odin?
Thank you
nothing?
Nope, because you will brick the device
No because the model number does not match, odin will not allow it to flash.
Prince comesy odin may allow it to flash but your un uncharted waters there so no idea what will happen
By any chance do we have any Odin method to root the Canadian Snapdragon versions, bypass the SM-G965W bootloader?
Nope. And dude a simple search would have told you that.
thank you all for the answers
you can make a rom out of the usa carrier firmware and flash it via twrp to your G9650 no problem. Don't let these noobs tell you otherwise.
@travis82
ahahahahaha I would need a guide to do it, so I was asking for the simplest thing, namely ODIN
I don't even know if it's better the G9650 version or the G965U1 version ...... in both cases, I have to use it in Italy with Italian SIM
He asked if he can flash firmware with odin, creating a rom and flashing via twrp is quite another matter lol
Can I flash the U1 Firmware with Mexico's Telcel CSC??
Hi guys, I made a quick comparison between 3 models (mine is the SM-G965W - Rogers) as recommended by some xda members. Some were saying it may be breaking the phone entirely, and some were saying it is working. Based on those specs all three models are pretty much the same including the Supported Cellular Bands. What is your opinion based on your expertise on this take?

Working roms/kernels for the Verizon variant of this phone? VS996

I plan on rooting and unlocking the bootloader but was unsure of which roms were compatible for the VS996 variant of the phone since I need the phone to be working on Verizon bands. Anyone have any experience on this.
Stock root is about it unless you don't mind missing phone calls and texts. I've tried about 6 roms and none worked without having to make a call for connectivity for a few hours, it's a pain for us Verizon users. Stock root works like a champ if that helps.

Agreed, stock root is pretty good, so I didn't bother with others. I don't need Pie yet, and can wait for it to arrive... no biggie.
When you unlock the bootloader (if you using the wtf guide) then you should already be on the us998 variant which includes verizon bands. So pretty much every rom out there works with it. Not all of them do though...

Flashing SM-G9650 (Brazil) into SM-G965U1 (US)?

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.

Esim functionality on unlocked AT&T version?

I was curious if anyone that had unlocked the AT&T version of the duo has been able to use the esim functionality.
The AT&T version does not support esim. I am trying to get an unlocked rom to test but so far did not find a copy of the image yet

If you could give a heads up if/when you do, that'd be great. I'll do likewise.
My other question is, there shouldn't be any issues flashing an unlocked stock ROM on an unlocked AT&T device should there?
Hardware wise, are they identical? With the differences merely being the preinstalled bloat, and it being (software) locked to a network?
