Questions before rooting S10 - Samsung Galaxy S10 Questions & Answers

Looking to confirm a few things before I take the dive.
The phone shipped with Android 9, but I've already updated via OTA to Android 10 once the SIM card was installed. Are there any precautions I should observe before proceeding?
Are there any side-effects? I know that rooting will trip Knox. Does that also affect the fingerprint sensor or call recording utilities like Skvalex? Or, for example, on my HTC phones, there was always a problem with decreased volume.
Can I use different firmware? My S10 came as a Factory Unlocked BSKO (G973FXXU3BSKO, United Arab Emirates), but could a different firmware be used to change the CSC, for example using the US firmware? The non-US label is triggering my OCD.
Is it possible to just manually change the CSC without using different firmware? Some posts here suggest that it's not possible, but there are some articles that suggest it is.
Would changing the CSC (if possible) really have any practical benefit?
Is there a power utility that will properly reboot the phone based on a selection of Rooted, Non-rooted and TWRP?
Thanks in advance!

Changing to N950F Firmware on N950N Note 8 and consequences?

Hi all I am currently thinking of importing the N950N 256gb Note 8 to here in the UK and have a few questions about the firmware. Sorry if its been answered elsewhere but there are a lot of threads asking slightly different things.
1) What differences are there between the N950N and the N950F versions of the software at the base level – ignoring things like Korean bloatware etc – I read somewhere the camera has a compulsory noise that can’t be turned off? (which is really annoying) Just wondering whether to stick with stock N. I presume all the stuff like 4G/LTE works with an O2 sim as the hardware is covering this.
2) From all the threads I have read you can’t put the N950F firmware on without using TWRP? (TWRP via ODIN then Firmware via TWRP)
3) What does TWRP do to the phone? Does it trip Knox? I presume this affects Samsung Pay which I am not bothered about but does this affect anything else? Android Pay for example? What about banking apps (ie Halifax, HSBC, Co-op, Natwest etc all have their own apps)?
4) Once I have the N905F firmware would I get OTA updates as normal?
Just curious, why do you want to use F firmware on the N?
Yes, you can not flash stock F firmware on a N, Odin won't allow you to do it but you can use TWRP. You would have to convert the F firmware to a Zip to flash it or flash one of the custom F roms.
Installing custom recovery like TWRP will trip Knox, you will never be able to use Samsung Pay. Secure Folder won't work either. It will also break Samsung Health but that can be fixed. Android Pay & banking apps should work fine with root hide. OTA updates will no longer work.

Basically I prefer having a silent shutter for taking quick and discrete street photography and the last thing I want is big sound every time I take a shot. From what I read that basically means the N firmware is a no no due to Korea having some ruling about it. In the UK this is as easy as having the phone in silent mode - I am currently using a Galaxy S6 with 128gb of memory and really like the idea of having a idea of large onboard storage with little hassle over memory cards hence looking at the Note 8 from Korea which not only has the bigger memory also is cheaper than the 64gb version here in the UK.
To be fair I don't use Samsung Pay as the UK support is currently not here with limited banks supporting it (or vendors accepting it) nor do I need Secure Folder so thats fine really. Samsung Health I used a bit on the S6 but not essential. If hiding root works for Android Pay and Banking Apps then it might not all that bad to be honest to have to trip the Knox (Obviously the warranty will go with it)
The OTA updates would have been nice to have as it would save me having to mess with manually updating over each time a new firmware update came out.- If I was to install F over the N could I then use ODIN afterward or would I be stuck using TWRP due to it detecting the Hardware?
Also I presume you can't add the F software onto the N9500 variant via Odin?

Ah, I see, in that case you really don't need to switch to the F firmware. I have a F from the UK & stock it did not have the toggle to turn off the camera shutter like my US Tmobile Note 5 did stock. Not sure if muting sound entirely muted the camera shutter as well but I do not like that method & have heard that does not work on some variants like you mentioned.
I purchased the F/Exynos mainly for the ability to install custom recovery & root. With root I simply deleted the shutter.ogg sound file (well I actually renamed it to shutter.bak), that took care of the shutter sound. Later on when I installed a mod to give me tmobile carrier features, that then added the camera shutter toggle.
I don't care for Samsung Pay either, not even Android Pay. I do miss Private Mode on my Note 5 which was replaced by Secure Folder but I can live without. Getting Samsung Health to work just requires a simple change in the build.prop. I forgot that root will also break Secret Mode in the Samsung browser but you can still use that in Chrome. Not a big deal, just mentioning it while I'm at it. I'm not sure if root hide will allow Secret Tab to function but I don't think it will get Secure Folder working. I haven't tried root hide yet.
Once you install TWRP OTA updates won't work. So installing a F firmware with TWRP won't change anything. And Odin won't let you flash firmware that is not for the phone. It does not matter if a different firmware is already on the phone. For some reason if you ever wanted, you can however flash your original firmware to get back to stock & OTA will work again but once you have tripped Knox by installing TWRP that is permanent.

Many thanks, I generally use Chrome or Firefox so I am not too fussed with the default browser
There are 2 variants on the Wonda Mobile website that seem like a good deal both 256gb with one the HK/China version Dual SIm (with the non rootable Snapdragon I believe) and the Single sim Korean Exynos version that I have been querying about. Its a shame either road root or just installing TWRP seems to break something!
One more thing - do all the usual Samsung account settings still work??

Unless you need the dual sim N would be the better choice IMO. With HK/China Snapdragon variants, they usually can be bootloader unlocked unlike the Snapdragons in the rest of the world. But development on them is usually slower. There was recently a post about getting root & TWRP installed on the 9500. Said to be working but others are questioning the process to do it. I haven't paid much attention to it though. Generally anything available for the F will usually work fine on the N so in the future if you want to install custom roms or mods you would be ok.
Yeah blame Samsung for making it harder for us to get what we want. But at least we still can, that may not be the case in the future. For instance, this is the first time I have had to purchase an international phone because Samsung US variants are locked down. All of my past Android phones have had custom recovery & root.
As far as Samsung accounts, yes it works fine. Able to log in, use Samsung's app store, Samsung themes. Not sure about Samsung Cloud, I don't use any cloud services. But I have tried Samsung Link Sharing (large file sharing) & it seems to be a type of cloud service. However my Smart View (screen mirroring) is not working, I'm not sure if that is a result of root though. I never tested it when I was stock. I have read complaints about others having the same issue stock. My Note 5 is rooted & it works just fine. I never use screen mirroring so I don't really care but it would be nice to figure out how to get it working.

1 - not much difference, but the F software comes with dual-SIM capability which the N software lacks. As the hardware is actually identical (as I confirmed by mistakenly tearing my N950N apart when I thought that I had an antenna issue), you could actually buy the N, buy a dual-SIM tray on eBay and in theory convert the phone into a true dual-SIM model with a 950F-based ROM although I do not know how to 'add' or double up the IMEI for the second SIM as my understanding (again I may be wrong here) is that phones sold as dual-SIM models have two IMEI numbers, one for each SIM slot. Your camera shutter sound rumor is correct - the Korean CSC's don't enable the menu to turn that sound off, though it can be deleted without changing CSCs. I would check with your specific carrier's model in your country and see if they enable it. If so, you could always flash their CSC to the Korean phone which would give you the menu. This would be especially fine if you live in the UK since the 950F is hardware identical to the 950N so there wouldn't be the weird issue I've been running into with my 950U USA T-Mobile CSC patch that I have a hunch is related to the way the CSC is sending instructions to the modem.
2 - Odin will not flash firmware between variants. TWRP is definitely the only way to do this right now, though there's no real drawback if you're using an imported phone and didn't expect to have warranty support in-country to begin with.
3 - TWRP is a replacement recovery firmware which is used to quickly and easily backup/restore any partitions on the phone (boot loader, modem, data, system, cache, EFS, etc), as well as flashing custom ROMs, kernels, mods, root apps, pretty much anything you can think of.
4 - OTA updates only work on essentially unmodified stock everything. If the phone says that it's software status is "custom", OTA updates will not function. However, there are 2 main considerations here. On the one hand, if you are running another variant's firmware you are going to be flashing ROMs for that variant anyway, and you can always manually update your boot loader and modem with Odin since Samsung firmware downloads come in separate files right from Sammy these days. Super easy to flash only the BL and CP (bootloader and modem respectively), then just reflash TWRP if it was overwritten.
Many thanks both - definitely things to consider here. Not done any flashing or rooting since I put Cyanogenmod on an old Note 10 tablet and before then a Note 3 and the old Desire series for Cyanogenmod again (I recall Clockworkmod was involved as well). But its good to know I can update parts with Odin or TWRP as required.
I am hoping tripping Knox won't affect Android pay or banking apps much (as I don't actually keep them in the Knox folder or anything like that - just use them normally) but as stated I could use the root hide to cover this.
I suppose OTA is a luxury as the Samsung ones on my S6 were slow enough but at least convenient due to its autonomy. I am usually of the mind if it don't break then don't fix it but don't mind delving into things if necessary so I reckon I won't touch the update stuff too much unless I have issues - though will get everything as up to date as possible from day 1 and when Oreo drops.
Really appreciate all the responses here - really helpful!

Just turn off the shutter sound in settings. You don't need to do anything else!

Can't do that if you don't have the option to. Not all Note 8s have the ability to do that (as well as other features) & it's not just the Note 8, many Galaxy phones in the past as well. It depends on the carrier variant & the region the phone originates. I some countries itxs illegal to turn off the shutter sound. If it were that easy, there wouldn't be so many threads about it. If you search for shutter sound either here on XDA or Google, you'll find many threads for different phones.
I have the phone now and downloaded the F firmware for the UK - however TWRP doesnt seem to want to flash the zip and keeps coming up with zip invalid format?
I grabbed the firmware using Samfirm so it should be fine? Am I missing a step??

If that zip contains several .tar.md5 files that is the stock firmware for use in Odin. TWRP can't flash that.
You need to download a custom zip. Any of the ROMs in this section will work as they are made from F firmware as the base.
I figured out this best way to sort the shutter sound was to simply root with Magisk and use Root Explorer to rename the shutter sound as per Shouren04's solution. Not the most elegant method but works fine - not sure what file the fast multi image shutter speed is though as that still sounds.
Magisk seems to not break Android Pay so can confirm this works and I paid for something today.
OTA no longer works but will simply flash the normal N rom once the next update comes out with ODIN and then reinstall TWRP, Magisk and resort - Samsung updates are slow enough to not warrant being a pain
Oddly enough there are fewer camera modes on the new Note vs my older S6 - I quite liked the video collage it made without resorting to another app!
Thanks for all the help

Burst shots sound should be shutter_multiple.ogg & video sounds should either be cam_start.ogg & cam_stop.ogg or camcorder_start & camcorder_stop.ogg.
Best way & is the method I'm using is to add this csc string to get the shutter sound toggle which turns off all those sounds for me.
<CscFeature_Camera_ShutterSoundMenu>true</CscFeature_Camera_ShutterSoundMenu>
But if you are using a fully stock rom, your cscfeatures.xml file might be encrypted as was mine. I'm using tmobile csc so I am no longer using the stock encrypted cscfeatures.xml.
Of if you flash a custom rom you should be able to add the csc string without any problem.

N950F or N950N given the choice, which one is better for updates?

Hi! Former Note 4 owner here, about to switch from One Plus 3T to Note 8. It has been a sweet ride with the OP3T but I am getting Note withdrawal already ! I just realized I buy (and lose) cheap styluses (styli?) every other week as I spend a lot of time editing pictures on the fly for our home business FB and IG ads.
Have a simple question:
In my country we have 2 variants available, N950F and the Korean N950N. almost same price, gladly both Exynos which is what I want. However, I would like to know if there is any advantage for any of them regarding system updates timing from Samsung, security updates and the like. Also, any chances of Oreo being rolled out for one of them earlier than the other?
I dont feel a need to root at the moment although just in case I would like to know if there are any major differences or ease of doing that for any of them . I did some research before posting the question and looks like N950F has more dev support but correct me if I am wrong.
I just need to decide on this "XDA world problem" to pull the triger. No one I know understand my conundrum and they look at me like I am from Mars.

n950n = no possible OEM jail time issue. F's are a hit or miss. Uk seem ok but the rest of asian and Oceania seem to have the dreaded 7 day jail time.

because the OEM unlock is there by default. My first attempt at a note 8 was a dual sim 950F and OEM unlock was not there. Not being able to root/flash twrp for 7 days and possibility of jail time every time a new rom or csc is flashed is not my cup of tea.

Well then, that makes me better appreciate my 256GB SM-N950N.
I was on the lookout for the 256GB SM-N950FD 'cause I wanted a globally unlocked, Multi-CSC supported, and unbranded bloatware-free Exynos device with support for OTAs. The Dual SIM support is a welcome added bonus. However, never came across a 256GB version of the SM-N950FD, only 64GB version, which I'm not willing to settle for, especially as I plan on keeping this device (my first ever Samsung Smartphone) for the next 5+ years (unless something a whole lot more useful becomes available) and I'm using it more and more as a full-fledged Pocket PC.
After you've rooted, do you always clean install via Odin in order to install the monthly security updates? Or how do you update the device? Please and thank you.

for monthly updates, no need to be rooted.
If you root then chances are you have twrp and probably are on a custom rom. the dev which makes the rom will update their Rom(monthly?) and then just flash that in twrp.
only thing you need to do is maintain your bootloader and modem up to date via odin. never flash these 2 firmwares that might be provided within roms or as seperate files as they are almost always for n950F.
I too have a 256gb version and it has been nothing but smooth sailing!

Thanks for the information. I don't have a custom ROM (frankly, I really like Samsung's feature-packed stock ROMs), I rooted so that I could switch the CSC to the Canadian Fido CSC (FMC) to enable WiFi Calling and also native call recording. Unfortunately, haven't figured out how to get either of those working yet, but also using Magisk root for other handy root applications like Titanium Backup, DisableService, etc., all while keeping Safetynet happy
In this situation, how would you suggest I do the updates without losing system data? Is there a way via PrinceComsy Odin? Thanks in advance.

updates meaning CSC ? just flash the note 8 CSC pack from tkkg1994
you can also manualy extract the files to your device(dont forget to set file and folder permissions after. I acctualy post updates for the Canadian xac region file in that dev,s thread so he can incorporate them in his flashable zip.
Regarding csc options for wifi calling, unfortuantely Fido is Rogers. they blacklist foreign imei codes. meaning that you need a device sold by them which is total BS.
this is the only "downside" of having a non-carrier branded device

Thanks again for the information. Sorry for not being clear, I meant entire firmware updates, like the security updates and the upcoming Oreo update. How would you flash them on the SM-N950N without losing data? I once attempted updating via Odin with HOME_CSC of the SM-N950N in the CSC slot, but it factory reset my Note 8. I then re-attempted with the HOME_CSC of the SM-N950W (the Canadian Note 8), but Odin threw back an error. Again, I'm not on a custom ROM, only changed the CSC.

stock csc firmware will wipe your fone at first but once its changed then it should not wipe after. it wipes when carrier/region is switched. flashing stock firmware from an F device to a N is not going to work.
logically is you flash the next korean full firmware update(bl,ap,cp,csc) it shouldint wipe. anyways if i remember right once csc was switched on your 1st attempt then it shouldint wipe on your subsequent tries. only thing that dies wipe is when sim triggers region to change.
if you have trwp then flash the CSC pack. it won t wipe that im sure of.

So given that logic, it would always wipe my Note 8. 'Cause after flashing the official SM-N950N (SKC) firmware via Odin (which makes it now the SKC CSC), I again changed CSC to FMC via @Tkkg1994's CSC Selection tool. Attempting to flash future updates would again trigger a CSC change from FMC to SKC, right?

I understand and can confirm that. However, that's used after flashing the official firmware updates, which results in a wipe in Odin as it's changing from FMC back to SKC, if I understood correctly. I'm looking for a way to avoid the wipe when doing the firmware update.
just don't flash csc part in odin next update. always use the CSC packs. of course since you flash AP then you have to reflash twrp each time and prolly have to format storage?
but all things put aside, you really should try his Iron man rom! make a trwp backup of your current state incase you want to go back.
So what about SM-N9500, the last update I received had Android January Security fix.
I jave the F edition.
Never went to jail. Flashed over 30 times different roms.

your on chinese snap dragon. totally different beast.
not sure if that makes updates come faster or not.
n950n just got an update 1 day before the Fs.
the rest are trailing at lest 10 days behind.
so id say the update speeds is:
Ns
Fs
U's
0's
W's

SM-N960F/D Odin flashing - blunder after blunder.... :(

Ok... So where to begin...
I've searched the threads for a few days now and tried several flashing methods and tools, but I'm having no luck. So please bare with me, and I will get into it...
I recently purchased a new Note 9 international unlocked model. I was super excited and ready to get it running. Except, I started it up and then no Bixby Voice. Unlike most, I prefer to use it and find it helpful to me regularly, so I'd like to keep it. Anyway, when pressing the button I received the much noted "Bixby Voice is not available in your country" message. Well, I found from Samsung support live chat, that this is because of two reasons. One, I currently live in Japan. Two, the phone is a Singapore model phone. My immediate thought was "Oh, ok well, I'll just flash it with another country's firmware then". Seemed easy enough. I flashed it with firmware baring an OXM csc, and after booting up I noticed the the VoLTE feature that was not select-able before was now able to turned on. "Ooow, extra win!" I thought, but of course same issue with bixby. So I searched and found a csc for a location that has bixby is available and is also a carrier unlocked Exynos chipset firmware (XEU). I flashed this, but guess what... still no Bixby Voice. Frustrated, I began looking into changing the Sales code. Using the *#272*IMEI# code and found that MM1 was the sales code for some reason. I changed this to XEU and the phone rebooted. I restored and then tried Bixby Voice again... same. Except, I noticed I also lost the VoLTE option completely. It doesn't even show in the menu bar anymore. I tried the code again to change the sales code back, but now I get error "Connection problem or invalid MMI code." So now, I lost that too. "To hell with it", I thought. I'll flash it back to the old firmware... nope. Now I get:
SW REV. CHECK FAIL. DEVICE: 2, BINARY: 1
This will sometimes change slightly if I try to flash a single part of the new firmware, BL, AP, CSC, etc...
I have done some research and found via the serial number that the firmware I should have installed is: N960FXXU1ARH5_N960FOXM1ARGD_N960FXXU1ARGC_N960FXXU 1ARH5_XSP (according to the Chimera Mobile tool)
I've obtained this, but I still get the same Revision error. I found that the one last one I successfully flashed is a newer version than the others. So now what can I do? Is it possible I can just manually manipulate the CSC details? I rooted the phone and got ES Explorer going, set all the access rights to R/W but I cant find the /System/CSC folder that people keep going on about. Did they do away with that on the Note 9?
It looks like I also have some regional troubles with the Play store too.
WTH... I'm really not sure what to do here. Can anyone please help? I'll be satisfied if I can just get it back to the stock firmware...
Decoding SW REV. CHECK FAIL. DEVICE: 2, BINARY: 1 come out to: Software Revision check fail, you have 2 and it's expecting 1.
That does indeed sound like you've installed a newer version and it's not letting you roll back the device. You may now need to wait for Singapore's stock firmware to be updated to the same or newer and get a copy of that.
who uses bixby use google assistant for peats sake!!!"!!!!

Hi willhemmens! Thanks for replying back.
I was also speculating the same thing about having to wait for the revision, but I know the people here are significantly more knowledgeable, so I thought I'd try to pick some brains. My first though was that there must be something in one of the package files that identify to the phone what "version" it is, and then perhaps that can be modified and then re-packaged. But if that were the case, this would be the best place on the planet to verify that. I have tools to un-package and repackage, maybe I'll make a duplicate copy and tinker around in it.
It looks like everyone is complaining about it. It's been a while since I rooted a device (7 years maybe?), so I hadn't realized Samsung took a dump in the downgrade pool. I also found some other new 'glorious' features they've graced us with-after the fact of course. Now, when I un-root... it's still flagged as modified! Woohoo. ....Fricken' KNOX. Now all of the nifty Samsung apps are blocked. Is it just me, or has Samsung turned a little extra Ass-hat recently?
Anyway, I guess I'll have to deal with this lame iOS quality version of Oreo until then... By the way, off the top of your head do you know where I can go to keep an eye out for that update to happen? All I know is SamMobile.com
Thanks again.

Hi Mikey! Yeah, I suppose your right. I've just been using it a lot and have gotten accustomed to it. Plus I enjoy creating my own custom Bixby voices, attitudes, and responses. Bixby on my Note 8 has split personality.
Luckily she doesn't randomly laugh in the dark like Alexa. If she did she'd fly out the window like a Note 7.

Actually, I just found a video on YouTube where Yakapa40 is able to unpack the xml files using some "cscfeature" executable.
@yakapa40
Is there any chance you might be willing to share your "cscfeature.exe" file for unpacking the feature XML files in the CSC?

Hi bober, don't know where else to post this, so posting it here...I have seen a bunch of your posts and it seems you've figured out a way to use Canadian CSC on the 960 F/DS...i have a few questions:
1- First step is install TWRP?
2- then root?
3- do I have to change the actual firmware of the device? Mine is a singapore unit
4- Once I change CSC, how are updates handled after that if I want to keep using stock firmware?
5- If I can't do OTA, then how will I update to the latest version and security patches? Do I download these for the Canada version? or the Singapore version?
Any help would be highly appreciated!!

i think you should weigh in what you want to achieve by changing csc and if it really is worth rooting for.
i rooted for custom roms, sound mods and just sheer control over my device.
but this comes with a price:
no samsung pay ( yet)( can always unroot)
tripped knox fuse, so probably no warranty. depends.(once tripped, this cannot be reverted)
misc apps detect root and might no longer root.(can always unroot)
so you should read up and get informed on what you need and if you need root/twrp.
concerning updates once rooted:
either use custom roms. BL and CP can be manually updated via stock firmware while custom rom keeps the system up to date.
or flash full stock firmware each time then re-root.
in both cases above, firmware files to be used are for exynos F devices. forget the canadian firmware, you cant flash that since it's for snapdragon devices.

Hi @yakapa40!
Thank you, this looks like it'll be a bit more convenient than the one I made previously. I'll put it on record for next time. Luckily I was able to find what prevented me from flashing the older revision CSC and modify that. So now I was able to use Odin to drop down my PDA and CSC while keeping the newer Bootloader and Baseband. I guess it's a bit of a Frankin'-Firm now. Whats weird though, is that now my knox sometimes shows tripped and sometimes doesn't; sometimes root checker fails and sometimes it passes.
I wonder if I grazed on something that's related to the knox handler... Nagh... probably just wishful thinking. Still weird though.

Hi @hkalltheway!
Bober10113 is absolutely right on this. Really, you need to know what exactly you are rooting the device for. If you don't have a set reason, it may be better not to root it. You can flash stock firmware and CSC all day long without needing a root. But if you want to customize the features (there's not really a lot right now by the way) and setup custom menus, layouts, or run CFW... Then you'll have to go the way of rooting. But again, there is currently no definitive way to "untrip" your knox. As he said, you can "unroot" but you cannot "technically" regain your unmodified status; even though you can revert back to a stock rom. By loosing this status you loose access to Pay, Secure Folder, and a few other things. I think there is a mod out there to get Samsung Health working again, but as far as I'm currently aware, that's the only one you can re-gain. Most of them validate against your knox value.
Regarding your questions.
YES! You should always install TWRP first before doing any 'messin'. This is your ultimate line of recovery and the best mulligan your gonna get from your device. Always follow the two step wonder on this:
1. Install TWRP
2. Boot into TWRP and create a full backup of your partitions (Before anything else). I do this to the SD card in the tray. That way it's always handy.
After this, feel free to play around, but keep in mind what versions/revisions your flashing. If you jump to a new one, it's not easy to downgrade -it'll take hours to download and rewrite the firmware you need and trick the phone into thinking it's flashing the latest update.
Regarding a changed CSC and the updates... You should have no problem getting updates. But Samsung sends out updates to devices based on the CSC. So, if you flash the CSC, the updates you get will come at the same time interval of the country and location of the CSC that you flashed. For example, you have a Sin model with Sin CSC just like me, but if you flash to a UK CSC, then you will get your updates at the same time that the UK get their updates. Etc, Etc...
For the OTA Updates, if your on a stock firmware you should get these fine. If they do not automatically update you can just tap the update button manually in settings to check for new updates and then download them. Some have said you need to turn off automatic updates, and some say you do not. This, I'm not 100% sure on this one. Also, you can manually update by flashing the newest version through Odin as the come in. Usually SamMobile.com is good about keeping up to date firmware that you can download with all 4 packs, nicely labeled for you.
Hopefully that helps you out a bit.

phone info tool and other root detect apps are notorious for reporting wrong Knox status.....
he wants a csc from a snapdragon to a exynos. so flashing csc from SD in odin is ill advised. so it will require root and files be either manualy modded or i have updated tkkg1994 csc pack to work on note 9. ive only added canadian region.
https://1drv.ms/u/s!AhXVLDDj8g3AgdkwkPIxwDu5ZFASuQ
in twrp backup:
EFS
carrier files
then flash zip.
i wont be held responsible for anything. Ive tested on my N960N.
should work on any F or FD/DS too.

Thanks for the help guys! The only reason I wanted root was for having VoLTE and Wifi calling working in Canada. One more reason is titanium backup so I can back up the device completely so it's easy to restore. Finally, I was curious how the scene is now and what else I can play with in magisk, as I've never used it. Thanks!

what is your carrier?
because Rogers blacklists non carrier phones. i believe bell might also do that too. So even if all is there and options appear, your phones imei code will be blocked from enrolling for wifi calling.

I'm currently with fido but thinking of switching to freedom mobile. Still too worried about all this rooting stuff that it seems the best thing to do is stay away from now and choose from one of the 2:
1- use wifi calling / VoLTE by getting the rogers/fido phone directly; that phone will not have dual sim capability
2- forget wifi calling / VoLTE and use this dual sim version, which has a lot of advantages while traveling
Seems like I'll stick to the 2nd option for now. Thanks for the help!

Need help with flashing firmware on Note 9 (noob question)

I have Note 9 (SM-N960U1) unlocked in USA. I am currently on AT&T.
I seem to have many dead spots inside my house so want to enable wifi calling but found out that I need to flash carrier specific firmware on my phone. As I am complete noob, have some questions:
1) What does flashing a firmware does? Pros? Cons?
2) I am currently on Android 10 (One UI 2.0 Build QP1A.190711.020.N960U1UEU3ZSL2). If I flash a new firmware, will my phone be downgraded to a lower version of Android?
3) If answer to @2 is Yes, how will I get latest Android updates? Will it depend on Samsung or AT&T?
4) Last but not the least, HOW THE HELL I FLASH THIS FIRMWARE?
Any help will be a great help. I have a interview on Friday so don't have much time to get this fixed.
TIA.
1) Flashing is a way to manually install or update firmware or operating system through the bootloader. This provides a way to restore the devices operating system during an emergency or failed OTA Update etc. The cons of this however is it is quite easy to mess up your device if you don't know what you are doing. And Flashing different firmware that is not originally meant for your device easily carries this risk. The bootloader is what tells your device how to boot the operating system and happens before any user interaction knock on wood you theoretically corrupt the bootloader or somehow mess it up you are left with a 1000 dollar doorstop. Im not sure how a carrier's firmware would react on an unlocked phone. I personally wouldn't risk it but it's up to you. I'm pretty sure that other users here have tried it you should look around and do your research. Remember this would not only be changing Android this would also change the CSC and Modem.
2) Android 10 has not yet been released for the Note 9 so I would assume that you are on the beta. You would need to factory reset and downgrade to Android 9 before flashing ATT's firmware.
3) Carrier's handle OTA updates. However im not sure you would even receive OTA's anymore.
4) You need to use Odin3 and get the firmware from somewhere like sammobile.
In conclusion I personally would advise you to contact ATT with your problem. Considering your interview tomorrow if something did for some reason go wrong you most likely wouldn't have time to fix it.

You have SM-N960U1 with One UI 2.0? Did you just buy it used? You are on bootloader 3, so you cannot flash another firmware with bootloader less than 3.

Question Any issues with changing CSC from CHN to XAR.

I just purchased a Galaxy Tab S8 (SM-X700 WiFi) in China and I want to replace the chinese firmware with US one. Are there any special considerations I need to know or can I just follow the rooting guide in the current post? Thanks!

You don't need to root to change firmware. Just re-flash your device with US firmware and if you want you can change code as well so it keeps getting US firmware updates instead of Chinese ones.
Rooting it will void warranty all together since rooting needs bootloader unlock and that trigers KNOX permanent and apps like samsung pass, secret folder will stop working permanently as well. Since they need KNOX to work, but since KNOX is broken/permanently disabled, then they won't work.
Thanks for the advice and information! I was hoping there was an option to update the region without rooting, but I wasn't sure. Cheers!

No problem, reason why you can flash other region is because those firmware are counted as stock. Only difference in them would be some apps that are preinstalled and such.
So as long it's stock firmware you don't need to touch the bootloader.
Might not be necessary to even flash a new firmware and loose data.

Under adb commends get a list of CSCs, see if the one you want is there. Then you can go back to the tool's main screen and change your CSC. Takes 10 seconds + a reboot, no data loss.
Worked for me both on my Tab S8+ and S22+.
