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.

Anyone found a fix for Samsung pay?
Hi guys and girls of XDA!
I have recently bought a used A5 2017 Dual SIM on eBay and I am in awe with its battery life even after the Oreo upgrade.
However, Samsung does not sell Dual SIM models here in Germany, my model comes from Iran (CSC: THR)
I have read the forum, but I haven't found answers to my questions.
I want to flash a DBT version onto my phone ans I have a couple of questions.
1) I have a DS model which were never available on a German market. Will Dual SIM work after I flash and will I get updates after I flash?
2) The german version of (mono-SIM) firmware, which is available on Sammobile still has A520FXXU7CRH9 baseband. I have already updated to the -I9 one. Does that mean that I cannot revert back o the H9 and will have to wait until german phones get I9?
3) My phone came with a sticker "Middle Eastern and African SIM only". Both slots work with German (and some other) SIMs as of now. Will this setting revert back and it will be locked to those SIMs, if I change CSC?
4) If I will apply the Combination CSC from Sammobile , will I get access to every region-locked option without tripping knox?
Thanks in advance!
Alex.
Anybody here? up!
I don't know the answers to your specific questions - but if the dual sim (Iran) phone you have works with your german sims why are you trying to reflash it?
Is there a problem or something that is not working?
I live in New Zealand and have an imported UAE (United Arab Emirates) 2017 A5 with dual SIM and it works just fine. I havent tried the second sim, but have heard of other people that have and it works as expected. The phone doesnt have any UAE junkware. You are right - the battery life on this phone is great. I did find the always on display uses more battery that I like though. Really wish they had an option that just turned the AOD on when you got a notification (new email/text/missed call etc) but Samsung don't seem to want to provide useful features like this. I came from a galaxy Note 2 and miss that little notification LED
If it helps, I see that the A520F and A520F/DS do not have different firmware - I have searched and there are plenty of posts on this forum where people have flashed Dual SIM hardware with the 'standard' A520F software and report that the dual SIM functionality works fine.
https://forum.xda-developers.com/samsung-a-series-2017/help/sm-a520f-to-sm-a520f-ds-t3704566
The DS model was never officially sold in new Zealand (the single SIM model was) but I have received the Oreo update and several security updates for my phone anyway since I bought it.
Hi, thanks for your reply!

VoLTE is not showing up in settings, for instance. I would need this option sometimes.

I get 26-28 hours of norml usage.
However one thing that irritates me is why it loses up to 10% over the night? Everything is closed and AOD is off, too. Other than that I had to uninstall Chrome because it literally ate up trice as much battery as everything else added up, including screen.
Not sure about your overnight power loss - sounds a litle high...
I use my phone very little and usually only charge it every 4 or 5 days.
AOD uses more power than I like (I have seen 1% an hour mentioned and that is probably about right), so I switched that off.
Really annoyed that Samsung havent made an AOD setting that only enables the AOD on when there are notifications (Missed call, new messages). I would really find that useful.
Have searched all over but cant find any apps that will do this.
For those interested, here is what happened.
1) I have a DS model which were never available on a German market. Will Dual SIM work after I flash and will I get updates after I flash?
Basically, it is the same model and the same firmware. The "normal" firmware for a non-Dual-SIM market works perfectly with a DS model and gets updates via OTA.
2) The german version of (mono-SIM) firmware, which is available on Sammobile still has A520FXXU7CRH9 baseband. I have already updated to the -I9 one. Does that mean that I cannot revert back o the H9 and will have to wait until german phones get I9?
The main thing is that ninth digit ("7") because it represents the revision of the firmware. As long as it is the same, you can flash it. If not you will get a brick.
3) My phone came with a sticker "Middle Eastern and African SIM only". Both slots work with German (and some other) SIMs as of now. Will this setting revert back and it will be locked to those SIMs, if I change CSC?
It didn`t happen to me.
4) If I will apply the Combination CSC from Sammobile , will I get access to every region-locked option without tripping knox?
I did as follows.
I flashed the DBT firmware from SamMobile and got myself a british code because it is a standard one in this Multi-CSC.
Knox not tripped. But VoLTE and VoWiFi still not working
Then I found the Combination ROM (FACTORY BINARY) with the same revision as the firmware (See question 2 about the "7").
I flashed it, dialed some USSD code. Then menu appeared from which I could choose the product code.
I chose DBT, wiped the data and cache and voila, I had a DBT phone with working VoLTE and VoWiFi otb.
Knox not tripped 0x0 !

Could you go into more detail, please? What USSD code did you dial?
So hello guys! I just bought a used Galaxy S9 after almost 3 years with my iPhone 7. I'm so happy to be back with Android since my phone before iP7 was the Galaxy S5. But unfortunately it was locked to a carrier in the Philippines (cause I'm from here so it's Globe locked). I've done some rooting and stuff with my S5 before and flashing firmware so doing this again might need some familiarizing.
I've done some slight research and somehow I didn't find any, or maybe I wasn't looking hard enough. There were different versions of the G960 but the one I easily familiarized with was the U and U1 which were the locked and unlocked versions...
Is it possible to unlock my phone by flashing a firmware? My model number is SM-G960F btw... thanks guys!

do not flash the U1 firmware on a G960F device! Teh F devices have the Exynos processor and the U versions have the snapdragon and are therefore incompatible regarding firmwares. The G960F is the international unlocked version. Go into the settings and factory reset it from within the operating system, download the latest G960F using the frija or samfirm tool with the modified Odin for your desired cell provider. Standard Odin will likely give you errors
Hi,
In order to buy an international S20 ultra 5g and use it in europe (france), I am wondering if flashing the device with a french firmaware could allow me to use it without issues, above all use samsung pay (I'm becoming blind and using card terminal in shops is sometime really tricky) ?
Look at sammobile and type in the serie number. Firmware will be there. If you're lucky your provider is there too. I don't think exynos versions of the software will work on Snapdragon. Good luck
if your chipset is qualcomm you cant use exynos firmware and otherwise
