Cross flashing enquiry - Samsung Galaxy Note 20 Ultra Questions & Answers

I bought korean model N986n
Samsung pay asking for korean sim and most of the flupboard is in korean language and weather app too in korean.
I was thinking, if I can flash N986U1 US firmware over korean one as both are snapdragon 865+
Any suggestions??
Btw, extremely in love with note 20 ultra and this feeling coming second time after HTC HD2

You cant flash that firmware, wrong model number, the chip the device has is not relevant.

Maybe you received an answer?
I bought a Korean version Note 10.1 tablet and have no trouble updating, as long as it is on the official firmware.
The problems you possibly face are LTE related.
Since you are looking at a Korean version, the LTE bands are limited on the phone and do not typically match the USA carerriers.
I took my device to the states......put a straight talk sim card in........3G works......HSDPA works.......but NEVER LTE.
However......when I took the same device to Japan.....I did manage to pick up a LTE frequency.
OH JOY
SO......if you are ok with 3G speeds.....go for it.
The is a global version....the 920F andfrom what I see,it has the correct freqs for AT&T and T-Mobile.
Still risky....and an expensive experiment.
I used to use a SK Telecom version (Korean) of the Galaxy S3 in the U.S. with AT&T, and I couldn't receive any OTA's unless I was using the SK Telecom sim. I think this still stands with the S6.
a friend of mine has bought sm-g920k, the contact in his list has automatically change it to korean, anyone can help?

Moving to Korea

I'm currently in the US on Verizon with a Droid Turbo 2 that I can't stand. I move to Korea in a couple months and was looking at purchasing the unlocked (snapdragon) s7 to use until I move and also pop in a Korean sim card when I get there. Will this work or ford only the unlocked international (exynos) model work in Korea? Any help would be great. I really want to drop this turbo 2, haha.
I believe u would have to 7nlock your phone by buying an unlock code for your korean carrier (SKT, KT, LGT)

Yes it will work because the unlocked model is sim unlocked, but not sure what LTE bands your Korean carrier will use so you might want to check that. Also, samsung phones are known to be region locked until you use the phone for few minutes in its original market. May be when you buy the unlocked model in US, use it for a day or so just to be safe that it's not region locked.
Personally I would go to Korea and buy the exynos version since that's the better version, you will have local warranty, no issues with radio bands missing etc.

Question on Proper Model

Hey Guys,
What would you recommend as the best model of the Note 20 Ultra to get? I have access to purchase the US unlocked, the International unlocked or the Korean Unlocked variant. I was concerned about using SamsungPay, yet I think I will let that ship sail. I am more concerned about overall performance and value. I will not be rooting. I use to for years on here, yet have not done so for the last 4 Note models. Just can't decided which would be the best one to purchase. Yet I need to get my pre-order in soon. I currently live in Japan. What are you thoughts?

my recommendation would be to get the version which has all the required bands to work well in Japan.
That said i would not get the international one though because it has the crappy exynos 990 in it.
both US and Korean variants have the snapdragon 865+. i known rooting doesnt matter but just for information the US and Canadian models cannot be rooted due to the locked bootloader

Thanks for your reply. Both the Korean and the US variant would work the same for LTE here... I'm going with the Korean version as it has twice the storage for the same price.... If for some crazy reason I do root it later, it looks like it would be doable with the Korean model in flashing a generic worldwide wide rom(?).. It seems there was pretty healthy development on the snapdragon Korean version of the note 10 plus...I don't think that I will ever push it has enough to fully use the chipset, yet it's a good piece of mind to have when spending so much money, that you got the best performance you can buy.... because any variant isn't 100% completely compatible with all the LTE bands in Japan, I would feel better getting the chipset that has the best energy efficiency as well... I'll be going with mystic white as it give me the greatest flexibility in swapping skins and cases, plus the grey framed camera bump looks better in my opinion

I am stuck in this too, live in Canada
I need Dual SIM ( not avail for North American version )
I need rooting
I checked but the HK bands dont work for my carriers 5G
So - should I buy a Note 20 Ultra with Exynos? where I am not getting its worth OR go for a Note 10 + instead International but with Exynos for $1200 CAD

I definitely wouldnt buy exynos this year..the 990 is total crap.
last year the snapdragon was still better but I don't think the performance margin was a big.
what carrier you with?

For me 5G is nice, yet not super important due to the fact Japan just turned on 5G for commercial use 2 months ago and still have yet to flesh it out properly. NTT Docomo, the largest of the 3 carriers, expects only 2.5 million subscribers by March 2021... In short I'm saying how much access will you have to 5G in your area?... Is it top priority if you are getting great speeds on LTE already?
I went with the HK version over the Korean version for the dual sim capability....
As far as rooting I think both the HK and Korean versions were enjoying some success on the Note 10+ forums... You might want to check how things went with rooting development on those models , with expectations for probably the same level of support

Problem in ROM region

Hello
I have a note 20 ultra bought from korea model N986N snapdragon international version, the problem is that I have several applications like the weather opens in korean language and several others, like samsung pay I can not use it (just in korea) and also the ESIM even I do not have the management option for the SIM card.
My question is, can I modify the rom so that I can mostly use samsung pay and ESIM or not.
Thank you
Good day, Guys.
I, too, bought my Note 20 Ultra 5G SM-N986N, Korean model, and I've been learning and tinkering with it for the past 3 weeks. So far, the only thing that is not working like it did with my Note 8, is the Samsung Pay. Now once I start the app I receive the error message "Couldn't read SIM card's phone number." I've been using the Galaxy Note since model Note 1, and I have had no problems with any model prior to now.
Since the Korean and US models are virtually the same, they both come out of the box with the same specs, sans-serif, the display (120Hz > 90/60Hz), memory size, etc., is it possible, or not advisable, to flash the ROM version that matches the US version?
Thank you. Cole

You can't flash the usa firmware on the Korean model.

Reflashing a ROM from a different region

Hello guys,
I hope everyone is doing fine out there regarding this worldwide pandemic!
I am here asking for help regarding my Note 20 Ultra.
I have a SM-N9860 model (i think this is China, Hong Kong variant) with Snapdragon CPU.
I live in Europe, Romania and because my phone was build for an other region, I can't use some of the mandatory apps(samsung pay), I dont't have access to updates from europe, I have a different layout for my keyboard, etc.
Now, here is the question: is it possible to flash the Romania's stock ROM version on my phone? Keep in mind that in europe there are no official Snapdragon variants and that means that I will flash an Exinos ROM on a Snapdragon phone.
I hope I found the right topic to post my question.
Have a nice day, everybody!
no you cant flash an exynos rom on snapdragon. I have the n9860 in israel im waiting for android 11 still.
never used samsung pay or google pay, cash is king.
That's not really what I wanted to hear
But, thanks God I did not atempted to flash a new ROM before asking!
Thank you for your answer!
Have a good night!
Same still waiting for Snapdragon Android 11 .... best phone
but last inline for 11 update with UI3.0
Either it's Hong Kong or Taiwan. Why did you buy Chinese version?
It was advertised as Snapdragon version and that's it. Nobody said anything about region, neither US nor China...

They schedule it at January 2021, so it's not that this model are late, it's just the other model get it earlY
I know this is contrary to what everyone says, but a few years ago I did successfully flash Exynos ROM on to a Snapdragon Samsung phone and everything worked fine, this might be anecdotal and I am not responsible if you try this yourself and brick your phone.
It was the Samsung Galaxy Note 9 which I ordered and received from eGlobalCentralUK (ceased trading), they sold Chinese variant phones.
Global variant had the Exynos 9810 chip (SM-N960F/DS)
China variant had the Qualcomm Snapdragon 845 chip (SM-N9600/DS)
I remember doing so because Samsung Pay didn't support any UK banks and only had Chinese banks. I have used Odin plenty before, so without checking on Google if it's possible to do this I just did it. I downloaded the official UK firmware from Sammobile and flashed the SM-N960F/DS (BTU) firmware on to the SM-N9600/DS Note 9. Everything worked to my knowledge, but I didn't do any specific tests like 2G/3G/4G on the phone.
Later when I got the Note 10+ and tried to sell my phone to MusicMagpie, they offered me £300 revised £0 for it because it wasn't UK variant and they can tell because it was Snapdragon.
