Hi guys, quick question... My good old Note 9 (Canadian variant: SM-N960W) is flashed with an unlocked/unbranded US firmware (SM-960U1), and everything's working flawlessly (Wi-Fi calling, VoLTE, OTA updates, etc.). The main reason I did it: Canadian carriers are useless morons, they take weeks/months to release updates, and I've been more than happy with the quick updates I get with the US firmware installed.
I would like to do the same with my Canadian Note 20 Ultra I will receive Friday, but I want to make sure it's still possible, with "Odin Patched", to flash a firmware from a different region on the Note 20 Ultra.
Someone on XDA did it? Did it go well, and did it break something?
Many thanks

I haven't seen anyone do it yet, you can test it out for us and report back how it went.
I too have a Canadian variant of Note 20 Ultra...wondering if switching to the US ROM will enable rooting option?
Yes you can do that what you will not able to get 5g network
I have us model U1 never gef 5g i changed to it rwc roger now get 5g

Thanks for the heads-up, I didn't thought about 5G, but glad to hear it's still possible to do it (flash a firmware from a different region) without bricking the device. I'll probably pick faster updates over 5G for now, considering I live in the middle of nowhere and have access to LTE only anyway
I have a Rogers Note 20 Ultra, I will wait for the updates because here in this part of Ontario, has 5G for whatever reason. I really enjoy streaming Xbox games from the cloud. Almost no delay.
You should be able to flash U or U1 firmware using patched Odin. Just make sure if you have a carrier locked version (not sure if thats a thing in Canada) to have it SIM unlocked before flashing anything, especially if you plan on changing carriers ever. After going to U1 firmware, you can access the service mode menus to enable bands for LTE, NR 5G and DSS. Canada uses 5G bands n38, n66 and n71 and DSS. The only band I don't see available in the US firmware is n38, although it may be available under another CSC like WWD or GCF. I have included a screenshot of the bands I've enabled under the Verizon CSC.
Has anyone with an N986W been able to flash the U1 firmware yet?
Has anyone tried it already? if its possible to flash SM-N986W to U or U1
Did anyone flashed SM-N986W to u or U1. Can you share the experience Please.

This can be fixed by flashing the home_CSC file of your carrier and then there are many other ways to fix this. So take this information lightly.

What he said :good:. Also you would be able to get on Beta on which a lot of 5G things were fixed / enabled so in fact that might work for you.
Only things i would want you to check before flashing the US firmware is:
1. Is it a dual sim phone? If No you are good.
2. Do you have E-sim Capability enabled? If No you are good.
3. What variant is your phone ? If Snapdragon you are good.
ohh if you are flashing US firmware flash the U1, no need to flash U firmware. Do check if you are sim unlocked because in case you are not and in future you want to sim unlock your device you will have to be on Carrier Firmware, if you plan to stay with your carrier for a long long time and or if you are sim unlocked this should not be of a concern.

Just as a heads up for future reference all Canadian new phone since December 2018 are Sim unlocked
For anyone still wanting to convert their N986W to US unlocked N986U1 I just wanted to say its possible. I used modified Odin and put the U1 firmware on my N986W. I was then able to install the 3 beta's. After a couple of days I switched back to the Canadian firmware. So for anyone wanting to try it, you should be good to go.

Hello,
I have a n986w (freedom locked) and i was wondering does every band work with u1? Or do we have to manually enable bands from service mode? And if i may ask where did you find modified odin and u1 firmware? And why did you roll back? I am still new to samsung phones, i had my fair share of modding android in past but sammy does thing bit differently so i am but confused about everything

Your N986W with freedom is probably not sim locked. I know mine isn't and someone earlier in the thread said that phones in Canada aren't sim locked anymore. So you should be able to proceed. When I switched to the U1 firmware I was receiving LTE signal on freedom. I did not test any other bands as I was just in my living room. There is a guide here on xda regarding enabling all the bands and there is a link to it from the thread I followed in order to switch to the U1 firmware. The link to modified Odin and U1 firmware is also in the same thread. The thread OP is warriorvibhu and its about switching from U to U1 firmware but you can follow it just the same and you can find that thread and the thread for sideloading the beta in the Guides, News and Discussion section. Sorry I couldn't add a link for you I have limited time right now. I rolled back because I just wanted to see if it could be done or not. The instructions were straightforward. Good luck and enjoy.

It did not trip knox as its official firmware. You will have to manually flash the betas. Also, when you get the U1 firmware, make sure that you download the one ending in ATID. That is the one required for the beta. I read both the guide for the beta flashing and the guide for flashing the U1 firmware before I proceeded. Also make sure you remove sim card b4 flashing U1. Have sim in when sideloading the betas and be careful you don't accidentally take an update between U1 and beta or you will have to re-flash ATID.

Hi,
I was wondering if its possible to flash US unlocked firmware onto the unlocked dual sim Taiwanese variant of the Note 20 Ultra 5G (SM-N9860).
There are certain features like Samsung pay that is somewhat limited for me because its still shows the region as Taiwan.
Of course I don't want to brick my phone but wanted to see my options in terms of changing the region to a US version.
Also, just to confirm, there is no way for this 5G variant to get 5G with US carriers, correct?
Thanks

SAme question here.. can anyone help please? also can anyone help in this issue:
I am living in UK, have note 20 ultra 986U1. all 5g Bands are not active, on android 11 (UI3.1) there was a way to access to service menu and enable all 5bands. and I was using the 5G here. now, I updated, and that can not reach seavice menu to enable right 5G band. anyone has any idea what should I do? even I can not flash with UK rom, as UK rom is for Exynos, but mine is snapdragon. any other idea maybe? or other rom that works with my phone and also enabled 5G bands?
do you think if I just change the CSC , my problem will solve? if yes, which CSC I must flash and how?
I've looked through threads of people doing the reverse of this. It's been a few years since I've had an android and was running nexus devices then. What's the process to flash an unlocked firmware on an AT&T locked 968U to the 968U1 firmware (assuming there aren't issues doing it)?
Are there any other pitfalls I need to be aware of prior to doing it other than the wifi calling?
If this is already posted somewhere else, please feel free to point me there. I didn't see any info about going from a carrier locked 968U to unlocked firmware.
Thanks in advance.

I just did this today went from TMB locked one to unlocked (For a family member) mine is unlocked. All went well no problems at all. Just download the U1 Firmware you want to flash and for CSC use home_csc (In ODin) so you can keep your data and probably the wifi calling feature too ( i did that all features are intact). Use the Odin and firmware from Ota and non Ota thread . Enjoy

Help!
Hello all, I have a Note 20 Ultra 5g that is unlocked and I'm looking to flash the original ATT firmware for this device.
Having this unlocked version on Firstnet has been nothing but problems and I don't have access to band 14 or wifi calling.
I see this thread is a little old but if anyone could help me out or send me in the right direction I would greatly appreciate it!
I have rooted some of my older phones several several years ago so I think I could pick this back up pretty quickly. I know over the years things seem to get easier and have probably changed quite a bit since I've last done something like this.

AT&T hasn't released any "official" firmware for the Note 20 series.
Since Samsung firmware is multi CSC, just flash any firmware with the same build number as the AT&T variant and use your AT&T SIM card.
Go to this thread https://forum.xda-developers.com/t/ota-and-non-ota-firmware-for-n986u-and-n986u1.4143833/
Make sure you know what device you have, U or U1. Then grab the appropriate version.
Fir AT&T U devices, N986USQU2DUCA or N986USQU2DUCA will work.
For AT&T U1 devices, N986U1UEU2DUCB is the most recent version.

Hello friends,
Recently I moved to Canada, I have the international model, G781B, I was wondering if it is possible to flash the canadian variant. Reason: 5G didnt work so far, tryied everything to make it work, even manually configuration of Bell network.
Comparing at the gsmarena.com, the hardware looks like the same.
I'm almost giving up and buying a new phone.

Most likely your carries uses mmwave 5g network, and international S20 FE 5g uses the other spectrums for 5g. There is no way a software flfash can change anyting, and I do not think that you can even flash software for thw wrong phone model, as odin check the BL version prior to flashing
I have a T-Mobile S22 Ultra that I have unlocked, I flashed the T-Mobile variant unlocked firmware on it to get rid of the T-Mobile bloat and splash screen.
I've since switched to Verizon, I haven't changed the firmware. The phone barely gets 5g anywhere and 4g barely works, feels like running on 2g. I am in an area where I have towers very close by for all carriers and this shouldn't be an issue.
We've only been on Verizon a few months and they've screwed up so much, like our billing and so I'm. So we're actually going to switch again to at&t, since it's the only thing that comes in up north where we travel. Would flashing an at&t firmware help with those types of things?
Yes.

Different providers use different 5G bands, which is likely why Verizon's 5G isn't working for you on T-mobile firmware. You might have the same problem with AT&T if you don't use At&T firmware.
You are correct that flashing the carrier's firmware will fix your 5G, and that is the simplest solution. You can simply flash Verizon firmware and it should fix 5G for Verizon network. Or flash AT&T firmware if you're using AT&T network.
If you don't want to flash another firmware, you can also unlock all bands to fix 5G on your current firmware by following the guide that @Ramsi Hartmann mentioned.

Sweet thank you
I don't want to take up a new post for this question. I am trying to find the correct firmware to use now that my t-mobile S22 Ultra is on the T-Mobile network. Can anyone link me please and thank you?

I have a T-Mobile S22 Ultra that I have unlocked, I flashed the T-Mobile variant unlocked firmware on it to get rid of the T-Mobile bloat and splash screen.
I've since switched to Verizon, I haven't changed the firmware. The phone barely gets 5g anywhere and 4g barely works, feels like running on 2g. I am in an area where I have towers very close by for all carriers and this shouldn't be an issue.
We've only been on Verizon a few months and they've screwed up so much, like our billing and so I'm. So we're actually going to switch again to at&t, since it's the only thing that comes in up north where we travel. Would flashing an at&t firmware help with those types of things?

Call Verizon and have them do a reprovison of the phone.. I had this issue when switching from Sprint to T-Mobile, when Sprint was around.. I had terrible cell, and data service in areas where I should not have.. After it was done everything went smooth not a single issue since.

This is the correct T-Mobile firmware: https://www.sammobile.com/samsung/galaxy-s22-ultra/firmware/SM-S908U1/TMB/
Download the latest one and flash it with Odin.

Wouldn't I need an AT&T one now so that the bands and everything work correctly?

Yes if you're on AT&T. But you said you're on T-Mobile and wanted that one?
Anyways, here's the AT&T one: https://www.sammobile.com/samsung/galaxy-s22-ultra/firmware/SM-S908U1/ATT/

Nah, I said I have a t-mobile S22 Ultra on Verizon and was having issues with Verizon and probably going to AT&T. Thank you for the link though I do highly appreciate it.
I have got a Samsung Flip3 US unlocked version. Have been using it outside US with and Indian SIM card from last few months without any hiccups. With Samsung Pay working as well.
Now, with the release of 5G services here in India, I'm not sure the bands that Indian operators use are unlocked or not in this. Jio (Indian service provider) says that you're using a non-5G device.
So, I was wondering if I flash an INU firmware to my device. Will it unlock the bands and also let me get OTAs from Samsung? Maybe if someone here did this already?
(According to Jio, this phone is compatible with their 5G network. Also, checked on gsmarena, the international version has the bands that JIO supports.) Since the chipset in international and US is same, I suppose the bands are already there in the device.
Thanks in advance for your help and comments.
Hi Jatin, I don't think flashing your US flip 3 with IND firmware, will fix your problem. The IND firmware is for the F711B model, you are on the F711U1 model. I would not try that. A lot of the F7711B firmware are multi-CSC, but not for the U1 model.
Thanks for the reply, @slysurfer.
I was thinking that since both F711B and F711U1 share the same chipset (Snapdragon 888), the F711B firmware drivers will work on F711U1.
I read some other posts in here (on XDA itself) in which someone with an EUX variant flashed INU firmware to it. Not sure the EUX variant is multi-CSC or not.

Yes, the EUX variant is multi-CSC (to a degree) I can flash any firmware from Europe to South East Asia, but as mentioned we can't flash any firmware from US/Canada.
Big >IF< you can OEM unlock the bootloader you can install twrp and disable the vbmeta and flash a U firmware over a U1 phone and visa versa. But even if you can do all of that it probably still won't work. Personally I'd take it to my local mobile phone stall and see if they can do it.
Thankyou @beanbean50 for your answers.
Sorry for the noob question, . Earlier when Samsung used to release 2 different hardware versions of the same phone like one with Exynos and other with Snapdragon, flashing the other region ROM was not possible.
So, I was just wondering, since both the regions (US & South East Asia) has the exactly same hardware, the networks bands in both of these must only be software locked. Thus, since the US version already has the hardware, can't simply flashing a different region ROM should work.
Again, if there are some other locks that prevent this, it's not possible to flash. Just like if on paper both devices are same, the only difference they have is, they are released in different region.
Also, I checked, both are also manufactured in the Vietnam.

Can you unlock the bootloader?

There is not OEM unlocking in under developer options. I have through other posts and things on how to unlock. I suppose it can't be unlocked in a straightforward like F711B can be.
I suppose this is the hard-stop that cleared my doubts.
Thanks one again, @beanbean50 for your time and answers. Really appreciated!!
P.S.: If you or someone you know have some experience unlocking a US snapdragon Samsung device bootloader, please do share. I might have to consider unlocking bootloader in the future.
