Hey guys! I just bought my S8 unlocked in Canada to use it with my sim card from Mexico, my S8 got blocked with that sim card and some forums recommended to use a sim card from the same country, do a 5 min phone call and everything will be nice. It didn't solve it but installed in my phone bloatware from Fido...
I fixed that lock region problem but not this one... Fido install as a bloatware Spotify, so I can only disable, cannot uninstalled unless I root my phone which I don't want to... Yet (at the end of the warranty) and of course, I want to install Spotify the premium one, but there's this little problem
app cannot be installed an existing package by the same name
I tried "uninstall" from abd with my computer and nothing... I tried using apk editor... Nothing...
If you guys know a possible solution another to root the phone, I'll appreciate
1. you can't root the canadian s8
2. change your csc to xac, this is the unbranded canadian s8 firmware https://forum.xda-developers.com/showpost.php?p=71525525&postcount=1413 this will wipe your whole phone and you won't have any fido bloatware
I get the same error unless I'm installing immediately after a fresh wipe. I dl everything I want then install it after setup.
It worked!!!

Just taped *#272*IMEI# on my call dial and chose XAC and that's it!! I didn't even care about restore my phone like fabric... So better do a backup if someone is gonna do this
Thanks again
Hi all
I just purchased the International S8+ dual Sim variant, the G955FD, from eBay.
I live in Canada and will be using both a Telus Sim and a Rogers Sim.
Is there anything I need to worry about regarding the CSC type?
I found this thread, https://forum.xda-developers.com/ga...ility-flashable-csc-selection-v1-0-0-t3605264
So it seems easy enough - I just don't know if and when I need to change the type.
And should I even be changing it to Telus or Rogers, since they don't have this variant?
And yes this is my first Samsung phone
And input is appreciated!
Edit: if it matters, I don't use wifi calling for either Telus or Rogers. I also plan on simply rooting the phone with magisk to make some mods, and put on Android pay
Just curious. Where was your Duos sourced from?

Great question.
As I did more reading on the device I checked the eBay listing and didn't see exactly where it's sourced from. I should have it in hand by Wednesday and I'll try to validate then. What should I be looking for?
Is there a specific source country that works better than others?

Firstly, congratulations on the new phone. I've got a 955FD as well.
It doesn't matter where the phone is sourced from, although if you want to check, you can go in to settings > about > software information > service provider information and see the CSCs listed there, in this format 'XXX/XXX/XXX'
The first one is the active CSC on the device at the time of you checking, the second one is the CSC for the SIM card currently being used, and the third CSC which can not be changed at ALL is the one from which country the device was sourced.
I'm in Pakistan so for me the CSC format is: PAK/PAK/MID
First two are PAK because that's the CSC for my SIM card and because it's the active CSC on my device, however the last one always remains as MID since that's where my device was imported from.
Canada has no CSCs available for the G955FD sicne it's the Exynos variant and the one sold in Canda is the G955W which is Single SIM and SD835, however the CSCs should work regardless of device variant. You can flash the CSC for whichever is your main SIM card, or whichever you use more often. Either Telus or Rogers, entirely up to you.
The benefits of flashing your carriers CSC is getting stuff like VoLTE and WiFi calling (and sometimes even 4G+/LTE+) to work. No harm in doing it since you're going to root anyway, so make sure to flash whichever one you prefer.
Magisk, rooting, mods, that's all fine, but do confirm properly about Android Pay before actually going ahead and rooting.
Samsung Pay will not work in Canada with the 955FD, and will definitely not work anywhere at all once you've rooted and tripped the KNOX warranty counter. Android Pay can be tricked into working by passing SafetyNet with Magisk, not sure if this still works or not though.
Other than that you should't have any issues.
If you've got any more questions, just tag me or quote this post and I'll be happy to help.

Thank you!
The break down is very much appreciated.
Is there any issue with flashing (via TWRP or Odin?) random CSCs?
Since there is no G955FD in Canada, I don't want to break anything.
I'm very comfortable with flashing and modding the heck out of Android phones, but Samsung seems to be a totally different ball game lol
I obtained a Galaxy S8+ G955FD Dual Sim from e-Bay as well, sourced from UAE. I was able to register US issued MasterCard and Visa on Samsung Pay.
I am on T-Mobile, other than not having WIFI calling, the G955FD works great. Rooting the phone would most likely break the Samsung Pay. So that is a decision you need to make.

No issues at all. Plenty of people in the US using the Exynos variants and they've all flashed the necessary CSCs when required.
Flash TWRP using Odin and then use the flashable CSC selection mod to choose whatever CSC you'd like to flash.

Thanks guys.
I'll assume that flashing TWRP is going to trip knox, right? therefore flashing a localized CSC is going to require me tripping knox.
Which hey, if Android Pay works fine then i don't need to use Samsung Pay i guess.
If i dont change my CSC, then will my phone receive OTAs when they're released in whatever country its sourced from?
Will changing my CSC to a Canadian one mean i'll start seeing Canadian OTAs?
What about manually flashing official images? Do i have to make sure that the file i'm using matches the CSC as well?
And lastly, are the S8 and S8+ images the same file? Or are ROMs for the S8 100% compatible with the S8+?

Flashing anything other than a Samsung Stock ROM will trip KNOX. Including TWRP. The Canadian CSC using the flashable CSC selector will have no effect on KNOX since it'll already have been tripped because of TWRP.
If you don't change your CSC, and are rooted with Magisk and have mods, you won't get any OTAs since the phone is rooted.
And no, changing to a Canadian CSC will not get you Canadian OTAs since the Canadian variant has the Snapdragon 835 and the 955FD you're getting has an Exynos 8895, so OTAs and stock ROMs are most definitely not interchangeable.
Manually flashing stock ROMs is possible, I suggest you flash the newest one available when you get the phone, which is G955FXXU1AQK7. And honestly, because there's been a major overhaul in how CSCs work on the S8, you can just grab any firmware and flash it and it'll stay on the CSC your phone came from because it can't switch to a Canadian one without you manually doing it.
S8/S8+ images are not the same and you can't flash S8 images on an S8+ or S8+ images on an S8.
Only S8+ (G955F/G955FD) stock ROMs will work on your phone.
However, since you're going through all the effort to root, change CSC and flash Magisk Mods, might as well use a custom ROM?
They get updated regularly so you don't have to keep flashing the stock ROM, and you can still have root, CSC mods and everything but with a few extra features and possibly better performance.

I got my S8+ over Thanksgiving and have been using this for less than 2 weeks. I received an OTA update a few days ago. It was an Android security patch dated November 1, 2017. So, I am getting security patch updates.

So maybe the first think i do is try and see how long i can go without having to root it / put on TWRP.
If i dont touch anything, including the CSC, will i receive OTAs as the source country gets them ? or am i out of band and therefore am on my own?

Just got the phone!
It's CSC is XSG/XSG/XSG which looks like "United Arab Emirates unbranded"
First thing im noticing is that it's not restoring my Google backups
Is this because it's a samsung phone and i need to use the Samsung backup feature instead?

It is indeed a UAE phone, good place to be sourced from since XSG gets updates fairly quickly compared to other CSCs.
What issue did you face when restoring the Google backup and how exactly did you try to restore it?
Some people have reported that the Samsung Pay app installed on XSG phones works well in other countries, so you can try that out if you want, otherwise Android Pay should work fine.

Yes, i actually just got a notification for an OTA. I think the December security patches.
Which is aweosme, so i'm not going to flash a different CSC because i dont think i need to at this time!
Regarding the backups; I was expecting to log in to this phone and get all my apps that were installed on my last phone.
But then i realized that htis is a brand new phone and i dont have a backup to restore to!
So i just manually installed the apps i needed and was on my way.
Lastly, yes, i just installed Android Pay and it works perfectly fine.
Thanks for all the help!

If your previous phone is an android phone and you use Google ID on that phone, you should have no problem restoring your apps. The Play Store remembers your Google ID and all of your apps should be restored if you log in with you Google ID.
Im noticing now that of my 2 SIM cards, one is usually around 80% strength, while the other is around 50% strength.
is this possibly an issue with using the wrong CSC for my region?
Or maybe since only one SIM can use LTE at a time, the other SIM is stuck on 2g/3g and it just has crappy reception becuase those towers arnt really in use anymore in my area?

Yeah, that is probably the case.
I had taken my 955FD to UAE earlier this year, used my local UAE SIM in slot 1 for LTE, and my Pakistani SIM card in slot 2 so I could still get texts on that number. Battery life did take a significant hit since the signal strength on one of the SIMs was quite low.
Changing CSCs may or may not have an effect on the signal strength. A good way to check is by using the SIM with poor signal strength in another phone with the same network mode, and see if you get the same results, if so, changing CSC will do nothing. If the difference is very large, then you could consider flashing the CSC although I wouldn't recommend rooting your phone just for a CSC change, especially if you aren't facing difficulties in making calls/sending texts/using data.
I have a 955FD XSG also. Using AT&T. I managed to enable VoLTE by quickly putting the sim on an att branded phone and returning the sim to my phone. I now have the VoLTE toggle and calls are placed over LTE but I can't seem to get the wifi calling toggle to appear.

Hi guys, sorry for this trivial question. I have not been doing flashing for years, as I got unbranded phones in the past 5-6 years.
Now it happens that I have got a Flip 3 vodafone branded, it is a F711B.
I do really hate that brand, so I would be pleased to get rid of that bloatware on my phone.
My mind suggests me flashing an unbranded stock firmware. So I have downloaded the one with CSC EUX. Apparently, I have an OXM carrier-branded variant.
Can I safely flash with Odin? Or do you recommend a different way?
Also, which options I should keep in Odin.
These are trivial questions, however, I do not want to mess my new phone.
Cheers
I tried doing that with a Puerto Rico (Claro) version of a S phone (don't remember which one it was) it didn't work, it simply didn't do anything.
now the change csc itself is not enough, you need to change the device manager, I paid $ 80 mdm carrier remove.

Hi.
In short I am asking someone who was the T-mobile firmware if they can extract the T-mobile unlock app. I am hoping I can use the unlock app without the need to reflash my phone to the T-mobile firmware.
Long story.
I thought my wife's phone was unlocked succesfully and flashed the unlocked firmware over the T-mobile firmware. Weeks later come to find out it's not actually unlocked we were just using a MVNO that is on T-mobile antenna... which I should have known. Really want to avoid making my wife setup a bunch of stuff again, even after backing up and restoring so looking for some help.
Is anyone able to extract the unlock app, or have a better way of backing up and restoring without the need for root?
TIA

What message are you receiving when you insert Non TMobile or MVNO sim?
AFAIK, you will need TMobile firmware for unlock to work. Newer TMobile phones don't have a dedicated unlock app. It is baked in connection settings.

Was afraid of that. It asks for an unlock code. Will probably have to just bite the bullet and flash back to the TMobile firmware.
Maybe flashing with Home_CSC will work and still allow me to keep my wifes settings intact.

Worth giving a shot with Home_CSC. Also Samsung backup works very well except Samsung Pay/Google Pay which you have to set again.

Ill probably try it tonight. As far as Samsung backup, did you mean smart switch? All the apps, contacts, photos come over but many apps still require setting up again Regardless thanks for the comments!
New T-Mobile devices don't use the unlock app anymore. Device unlock requests are done through connection settings.
Ended up flashing back to T-mobile firmware using Home_CSC instead of CSC and I was able to successfully unlock as well as keep my wifes settings...
But i tried flashing back to unlocked firmware using Home_CSC and couldn't boot. Said user data was corrupt. I tried 4 times without any difference. Luckily I was able to flash back to T-mobile firmware again with Home_CSC and it worked fine
This may be common knowledge I wasnt aware of but it appears:
Unlocked firmware + Home_CSC -> Carrier Firmware is ok
BUT carrier firmware + Home_CSC -> Unlocked Firmware is not
Thanks to anyone to commented and read.
It's contract there I believe
Hello,
I have an A536V (I bought it used and it's not paid off) and every time I try to flash a different firmware (XAA, TMO...) it just says secure check fail.
The phone should be unlocked because my T-Mobile SIM card works for a few seconds until the signal just goes away and doesn't come back. So my question is, what am I doing wrong? Why can't I flash any other software?
P.S. I used the SamFW tool to change my CSC to whatever was available (on VZW software the only ones available were FKR and GCF, neither of which bypassed whatever stops my SIM from working).
Please help! Thank you!
secure check fail means its either the wrong firmware or to low of a revision than whats on the device as in you cannot flash older firmware But that being said you are bassicly admitting you have a subsidized phone thats blacklisted due to non payment. So no other help will be given more than likely here
Look at this: https://www.androidauthority.com/how-to-unlock-a-verizon-phone-1131315/
"Once you hit that 60-day mark, Verizon will unlock the device automatically. However, you’ll have to pay it off in full if you want to take it to another carrier."
Move to Verizon. Easily solved here. (Well maybe. I don't know what Verizon thinks of that with buying a used phone not fully paid off.)
I have the same question, but I have a Verizon phone that is actually paid off
EDIT
I just wanted to change CSC to remove the ugly Verizon branding on boot
It stayed unlocked when I switched to GCF firmware (XAA was not available since this is technically a hardware revision from the usual A53 5G, this is the A53 5G UW - ultra wideband model)
Anyway I found out from someone else you can use SamFW to do this for free in the ADB tab
