Ok so I really y need your help guys!
I've asked this question a few times in the past about other phones I ended up not keeping, but I'm now intent on making this work.
I'll keep it simple: can I flash a Canadian CSC on a Global phone? Will this brick the phone?
I don't quite fully understand how the CSC relates to everything else, but the times I tried I couldn't get the CSC to change. Plus I'm concerned because I have a dual sim model (which doesn't exist in Canada) that is Exynos, where the Canadian model is a SD.
Through my reading I think it could work but I don't want to have a $1000 paperweight in the end, but I'm have piss-poor reception, Samsung Pay doesn't work, VoLTE doesn't work, I can't block phrases in SMS and the list goes on. I want to try this to see if it helps anything... Failing this I may cut my losses, sell the phone half-price and just get a non-Samsung device; I'm getting so aggravated at this it's not even funny.
Thanks!
PS: if you are wondering why I didn't buy a Canadian phone to start with, let's say it's a complicated answer but can be summed up by the dual SIM cards.
A CSC defines that carrier settings of the phone. As long as you use official Samsung firmware and do it properly it will not brick your phone. Look at sammobile first to see if Canada has a stock firmware. However, doing this will mean all data is lost, are you flashing carrier based firmware or your country's global software?
I just did a search and on the S8 there was no difference between the single sim and dual sim softwares and on GSM arena it classes them as the same. Do you the have snapdragon or exynos version?

I don't mind data loss, I have back ups and really not much on the phone anyway. Canada has stock firmwares for each carrier, so to answer your question, carrier based. But my huge deal here is the different configuration between what is available here and what I have: I surely can't flash the entire firmware based on a canadian phone... I would lose my dual SIM and surely the difference processors would brick the device. But I'm not really sure if I can mix and match, i.e. pick a CSC for my carrier and everything else (PDA), and if I can, what do I chose?!
See where I'm at... because I can't flash the entire firmware I think I'm s.o.l.
I'm afraid the situation isn't that good for you.... I am assuming you have the Exynos varient since I cant see a dual sim version of the snapdragon variation which means no Canadian firmware is available for your device at all. Since I'm in the United Kingdom we usually swap our CSCs with ease but it appears if you didn't buy the snapdragon version your out of luck at least for now. I'm sorry I couldn't be of more help you could sell and get the Canadian version but you won't be able to dual sim or get another phone I left from the S6 to oneplus and had a really good exprenice but that was on the 3T so I'm not sure what they are like now
Again sorry I couldn't have been more help:crying:

Figured as much... I'll move on I guess...
I'm trying to get the USA version of Samung Pay working on my SM-G9600 (International Unlocked Snapdragon S9). Unfortunately, my active CSC is currently set to TTT (Trinidad/Tobago... not sure how, I flashed a CHO firmware, haha), so even when I have my Samsung Account and AT&T SIM card inserted, opening S-Pay just gives me an error, "Unable to connect to Samsung Pay temporarily. Try again later."
To remedy this, I think my best option would be to flash a new CSC from a different region? However, I don't really understand how Samsung's CSC system works; I've tried researching it, but I haven't found anywhere that really explains in detail what CSC actually does, single-CSC vs multi-CSC, etc... Can anyone give me a summary of all the major parts? Or at least point me towards a good resource to learn about it?
However, I have more practical, direct questions:
Could I flash my G9600 with just the CSC (or better, HOME_CSC) of a USA Snapdragon variant, like the U1? Or would that break things, since it's a different model number? Would that be likely to get me a working Samsung Pay?
I guess I should flash the CSC (or better, HOME_CSC) of a different region that also carries the G9600? Of the regions that carry the G9600 (China/Latin America), I believe the only countries that support Samsung Pay are Brazil, Mexico, and Puerto Rico (and Hong Kong, but only with Hong Kong banks? I think.) If using a CSC from the US is a bad idea, which of these would be best? I'm guessing Puerto Rico, since it's most closely related to the USA, but the only PCT firmware on Updato currently has the v1 bootloader, but I'm already on the v2 bootloader (2ARE6), so I don't think I can use it.
I would guess that the next best option would be Mexico, since it's pretty close to the USA, and I see a firmware with the v2 bootloader for it on Updato. However, I'm not familiar with that region code. Is MXO a specific carrier in Mexico? Or is it the carrier unlocked firmware, like U1 is in the US?
MXO is unbranded bro and working samsung pay.
I wanted flash a specific carrier csc but I couldn't set TCE always appers CHC.

Did you end up flashing the MXO ROM? If you did, do you still have dual SIM capability after that? Thanks!

Yes! Dual SIM is not affected by which SM-G9600 firmware you flash. The thing to be wary about would be if you tried to flash a different model's firmware to it (e.g: G960U), since there is no Dual SIM among the U models. Although if I had to guess, the Dual SIM settings would probably still work fine (assuming the U firmware didn't brick it otherwise).
Have you found a fix for this problem, are you able to use samsung pay here in US?
Did you change the csc only or flash the whole frameware?
Thank you in advance.
I'm also wondering about flashing just the CSC on a dual SIM device. I have a Note 9 dual SIM that will not get Volte, so I was thinking about flashing the U1 CSC to see if it would fix it. Does anyone have any advice?
You guys are so good at this compared to me. I felt like a noob ?.
I posted a question a few days back but not getting a meaningful answer. The goal is to do minimal changes but get Samsung Pay working.

I recently obtained a Samsung S20+ SM-G9860. However, I am in the US and am intending to flash the AT&T firmware for the SM-G986U. When I try to do this, I get a secure check fail on the PIT file due to the differing model. Is there a way to circumvent this? The two models have identical hardware from what I can see.
Is it possible to do this, and what is the process for doing this if it is indeed possible?
You cannot flash a rom built for a snapdragon chipset on a phone with a exynos chipset
Be thankful there is that safety check built in. Lol

It's not Exynos, it's also a Snapdragon.

It's the Hong Kong variant. It does appear to be a dual SIM, however.

The hardware isn't identical, SM-G986U is a Single SIM Device, your's is a Dual SIM.. TGY is the CSC in your device and even if you could flash SM-G986U Firmware the CSC would not change, it will still be TGY. If you're looking to get full AT&T call functionality on your device it's not possible as the CSC doesn't support AT&T compatibility. Firmware is CSC specific as well.

But mine has two IMEI numbers though 1 for physical and another for esim, HOWEVER the esim option to add another QR code for another network is not visible. Its like the device is locked for VERIZON esim use only.
Oh well, guess gotta wait for another few month for newer updates to be able to use another network esim or firmware flashing that can enable this option soon...

If your device is the SM-G986U it's a Single SIM Device which doesn't at this point doesn't support eSim. Does the SIM Management Screen actually display the word "eSim"? Share a photo please. The device is likely still locked by Verizon. What is your motivation to change the Firmware to SM-G9860, do you live in Hong Kong?
Im sorry unfortunately I cant post links for my screenshots or upload any pictures..

I bought my phone online.. When I start up my phone it says Verizon, but its unlocked though because I can use any country physical simcard. Like right now im using my local simcard in Malaysia. I live in Malaysia and the reason I want to flash rom my SM-G986U device to Hong Kong firmware is so that I can use any eSim network in my country for my other network phone number.... If its a software for eSim that I can get for firmware that will be very helpful. Because the main local Malaysian samsung s20+ 5G firmware model is base on Exynos 990 which I doubt will fit for my US phone model..
I don't think you can flash SM-9860 Firmware onto your device but even if you could you still won't have eSim capability. Mix and matching firmware typically has more success on Exynos International Variants since they are Multi-CSC Enabled Devices. So if you have a British CSC (VOD) you may have success flashing German Firmware (VD2) since both CSC's are already stored in the device however even then some call features may not work. Snapdragon Devices don't have Multi-CSC's and as mentioned previously the Firmware is CSC Specific, they're made for one another. IF you had an Unlocked Bootloader, which you don't, there may be a method to modify the CSC once you root the device.. I did follow a thread a couple of years back where a gal had some success modifying her CSC on a Snapdragon Device but I believe that was a Galaxy S8. Also, I'm still curious if the word "eSim" actually appears in the SIM Management Screen on your device.

Damn.. that is some nice insights.. I read a thread somewhere too that US SM-G986U cannot and will not be able to enable its OEM or unlocked bootloader.. the eSim actually doesnt appear in the Sim Management Screen on my device. I really want to upload some links of the screenshot but for now I cant do anything as Im a new member.. I just have to wait for the network shop to open up to change my current esim card to physical simcard.. its been 2 months plus of this coronavirus lockdown and our network providers cant do much about it too..
Anyways I really appreciate the insights, like you said even if I could flash in Hong Kong SM-9860 in to my US SM-G986U, I might run into some software or calls dysfunctionalities..
Anyone got th atct update for the sm-g9880 yet? Seems the u.s has got this update before Asia?

Hello,
Newbie question here coming from someone with Exynos model SM-G988B/DS (purchased while visiting Singapore):
Can I make this phone fully compatible with North American carriers? I'd like to use Wi-Fi Calling and VoLTE - but my Canadian carrier says that this phone is not eligible for these services because it's not a North American variant. A USSD code provided by my carrier was not successful (it said "invalid MMI code").
Even though I'm not entirely comfortable flashing different firmware onto Samsung phones - in this case I am desperate to do it (if it can be done to achieve my purpose at all...)
Now I'm kicking myself... wishing I knew that these calling features might not work back in Canada.
Thank you for your advice.
this is odd.. my phone is purchased in Malaysia, the country north of Singapore, and we have different CSC codes.
Wi-fi calling and VoLTE is working fine when i am in Singapore using a Singaporean SIM Card and when i back home in Malaysia using my Malaysian SIM Card. (But this is on the Samsung Note 8, have not gone to Singapore since i got my S20+ shortly before Malaysia shut down the borders due to the Covid-19 outbreak)

Short answer = you can't. You will need to change the "region key" (csc) by using samkey. If you flash the firmware belonging to different region with different csc code, you will not get any ota update at all. Therefore you must flash the firmware of, say, Canadian region, as well as changing the CSC to same set that Canada uses.
However: do *take note*, do *not* flash snapdragon firmware to exynos set vice versa.

You're saying it cannot be done but then are telling me that it can be done using samkey. So which is it? Can I not flash North American firmware with the appropriate CSC?

This is obvious - I would never do such a thing.
As its an exynos device it won't play well with usa networks and you cannot flash snapdragon firmware obviously. If you were in Europe this would have been easily done by changing the csc to say UK BTU via samkey and flashing the BTU firmware etc. Usa is a more complicated given the bands are different over there. Also you probably won't get carrier aggregation and volte / WiFi calling is a lottery! Plus usa networks aren't as chilled out as the rest of the world and have hissy fits if you don't use their branded devices. Charge way more than most other countries too! ?

Not exactly. I'm in Singapore, using Taiwan set, with HK firmware & csc. It's 3 different regions

You *must* do both: update firmware *and* change csc. Now Samsung has locked the csc changing. You can no longer change csc by just flashing firmware of different region. It won't work. Change csc, then flash the firmware.

It is different region as the csc is different.
In your case it is complicated. You can try to flash in your local csc file via odin. Just the csc file nothing else. See if it will work.
The firmware for exynos and snapdragon variants is very different.

He cannot and must not flash sd firmware into exynos phone. It'll brick the phone. Taiwan and hk is sd variant.
Ok - thank you for your responses so far.
So what is the absolute best thing that could be done in order to be *the most* compatible with North American carriers? What CSC should I be aiming for and which firmware to be exact? Could someone please link me to the appropriate files? I'll do my research once I have an idea of what to start with. (If it won't work - I obviously won't bother with it... but I think I should do some more research before I completely give up...)

you're in tough luck. USA bands are different from most of the world (https://sea.pcmag.com/smartphones/3...-americas-first-unlocked-all-carrier-5g-phone). To top it off, your set is exynos, and even if you can get firmware that works for USA set, it is most likely will be in snapdragon.
Btw, exynos version will never support mmwave in USA carriers, simply because exynos version does not have mmwave antenna.
I would suggest you sell that exynos set / exchange it to snapdragon set. With snapdragon, you have more luck finding compatible firmware.
Well... I cannot particularly exchange this device now that I'm in Canada and I've had it for over a month. And no one here would want to buy it since it's not local to the continent. I'm stuck with it here now.
I'll just use it for a year and then get some other new phone next year that's local to my region. There's a few other things I do not like about this latest Galaxy anyway... and I cannot see myself using it for longer than a year. What a pity though - I used to be such a die hard Samsung fan until this latest flagship. They screwed up so many things, namely - the battery life and camera quality.

That's precisely why I do not want to use local version here, which is exynos, the one you brought there.. snapdragon version is *miles ahead* and really is the flagship quality. I don't have issue with camera, the battery is insanely efficient (I have 2 WhatsApp, 2 telegram, email real-time-push, wechat, line, fb, etc) and I only drain 4% per 8 hours at night with all notifications still coming in
Yes, that's the snapdragon version, the real s20 flagship.
Try switching off 120hz. I'm happy with my 60Hz. Battery is pretty good, i usually unplig my charger at 630am.. It'll last me to 10pm with about 30% charge left.
This includes occasional messaging on telegram and whatsapp, some email checking and Facebook browsing. Working hours I'll be on office wifi. Lunch hour and after work 530pm to 630pm is my pokemon go hour which is the only time my wife let's me play games.
My phone is s20+ 4G variant, usually on 4G+, dual sim and 1 micro sd card (one of the sim is the esim). My display is at wqhd+ at 60Hz.
So far im happy with the battery life.
Just this morning, taking advantage of my wifes absence, did some gaming, namely war machines, the tank fps game and pokemon go.. From 630am to 1130am, Facebook and tiktok when I'm preparing and eating my breakfast. my phone is left with 60% charge.
Hello,
I would buy Snapdragon / Hong Kong version because I hate Exynos problems, but I'm a bit confused about CSC.
I've read the topic, and I understood that I can't flash Exynos (European) firmware on the Snapdragon / Hong Kong version.
Some people bought Hong Kong version and works very well in my country frequencies, but I would use Samsung Pay.
What will happen if I change CSC/flash to any european CSC? It would work or not?
Thank you a lot.

Samsung pay might work if the card supports samsung pay. But no way to know for sure until someone test it themselves.

You *must* do both: update firmware *and* change csc. Now Samsung has locked the csc changing. You can no longer change csc by just flashing firmware of different region. It won't work. Change csc, then flash the firmware.

Hey man, can you make a link a guide on how to change the CSC and Flash the firmware?
I have an s20 Ultra Exynos from Indonesia, and want to change the to Korean CSC and flash the firmware.

you're in tough luck. USA bands are different from most of the world (https://sea.pcmag.com/smartphones/3...-americas-first-unlocked-all-carrier-5g-phone). To top it off, your set is exynos, and even if you can get firmware that works for USA set, it is most likely will be in snapdragon.
Btw, exynos version will never support mmwave in USA carriers, simply because exynos version does not have mmwave antenna.
I would suggest you sell that exynos set / exchange it to snapdragon set. With snapdragon, you have more luck finding compatible firmware.

Wait what? Exynos definitely has MMwave antennae! If it doesn't that's news to me. Where did you see information that states that?

On Exynos & mmwave: https://www.bitfeed.co/2020/03/15/s...s-completely-disassembled-no-antennas-mmwave/ and https://eu.community.samsung.com/t5...-5G-supported-5G-networks/td-p/1577262/page/2
btw, you cannot flash Korean firmware to exynos. Korean S20 are all now using snapdragon
How do i unlock my Sim Network on Galaxy A71 5G T-Mobile carrier?
Please guys, how do i unlock my local sim network here in Nigeria?
I bought a second hand used Samsung Galaxy A71 5g from a vendor here. My local network won't work on the phone, telling me it's locked. The phone runs on a Snapdragon chip.
I'm really desperate about unlocking the network, how to i go about this?

Short answer = you can't. You will need to change the "region key" (csc) by using samkey. If you flash the firmware belonging to different region with different csc code, you will not get any ota update at all. Therefore you must flash the firmware of, say, Canadian region, as well as changing the CSC to same set that Canada uses.
However: do *take note*, do *not* flash snapdragon firmware to exynos set vice versa.

What are you on about ? Short answer = Yes you can! I've been on Germany CSC (Im UK based) I've been on Abu Dhabi region and i was getting my OTA updates with no issues i think you were confused with a root as that breaks your phone.

Well... I cannot particularly exchange this device now that I'm in Canada and I've had it for over a month. And no one here would want to buy it since it's not local to the continent. I'm stuck with it here now.
I'll just use it for a year and then get some other new phone next year that's local to my region. There's a few other things I do not like about this latest Galaxy anyway... and I cannot see myself using it for longer than a year. What a pity though - I used to be such a die hard Samsung fan until this latest flagship. They screwed up so many things, namely - the battery life and camera quality.

Did you able to change to csc or firmware of taiwan version
They seem to be the same device only for different markets, so would it be possible to flash a b version firmware to a u device? Thanks!
That's not a silly question actually as it wasn't possible before due to hardware differences (Exynos chipset for Europe et Snapdragon for other markets), but now it's only Snapdragon chipset for all markets so... I'll be interesting to know if it's possible too and what it brings that european firmwares doesn't have. Otherwise, there's no point for me.
My interest in this is to remove limitations added to US devices. Idk if software changes would help but stuff like oem unlock for an example.
I'd assume you'd need a rooted device with an unlocked bootloader.
I doubt Samsung would add the US into the OXM roms though it might be worth it to check the firmware you have.
Wont be possible
Thats not the first time samsung got snapdragon variant in différent Counties
Back in the day it was possible de flash BR snapdragon on canada and usa snapdragon or with asian snapdragon
Than they came up with région lock ,
First version of région lock u was able to flash BR snapdragon fw on Canadian and USA and it excluded the Asian months later they updated their région lock so even BR won't work anymore
Its onlt North American FW on North American
You can give it a try it should just block your phone on bootloader till u reflash the your u version or u1 or w
Yeah, whenever I have some time I'll give it a try. I thought region lock was just on new devices and for network access, I didn't know the hardware itself had locks even being identical. Thanks for the reply.
How very Apple...
