Question Downgrade firmware from C.26 to C.25 - OnePlus 10 Pro

Hi,
im on EU- Stock, nothing modified.
I looked left and right in the Internet ;-) , so sorry for the maybe stupid question.
The only solution I found is rolling back to Android 12 and go from there.
C.26 breaks my email access to my employer (Mobileiron) , a fix might take a while.
I have the C.25 full OTA file here, developers options activated, that's it.
So, is there a way to downgrade the firmware from C.26 to C.25, idealy without loosing data?
Thanks.

[Q] Rooting and OTA's

*I'm getting this out of the way first.* I know this may be a very stupid question to some of you, but I've looked on multiple threads and posts about this topic and have gotten mixed results and answers, so I thought this would be the best site to get a definitive answer.
I just got my Nexus 6 through AT&T today and wanted to root it to get rid of the very annoying AT&T splash screen you get when you turn the phone on. I know how to root and unlock the bootloader, but when I do that will I still be able to get OTA updates from Google without any fancy flashing or things like that? I'm sticking with stock Android and I'm not installing any custom ROMs. I know on a lot of other phones you can get OTA updates when rooted, but you have to install them manually. If it's too much of a hassle I just won't root it.
Thanks in advance,
Robert (Mokedoke)
It's better explained in other threads. But no, you can't take OTA. If you unlock only I believe you'll be fine. But as soon as you modify system files it won't work for OTA. Lollipop checks for these changes and the install will fail out.
You won't be able to get the OTA, but you can manually flash your phone to get the latest ROM and with out loosing data. Search the forum there directions to show you how.

[Q] Lost in the Sauce with rooting 4.4.4

Hey all,
As the title aludes to, I'm totally lost with rooting my note 3 running 4.4.4. I've been pokling around this site for a few hours but I'm not really seeing what I need. Basically all I want to do is be able to tether my note 3 (it's SIM unlocked on an african Carrier,. the phone is from at&t originally though). As I understand it, i need to root my phone in order to use this feature (f*ck AT&T). Anyway, I did use the search but I can't find any info on rooting a phone that is already on 4.4.4. Do i need to downgrade or is there an a way to root 4.4.4. In any case could someone give me a full step by step or point me in the right direction? I hate to be that guy posting duplicate threads but I'm kinda stuck. Sorry/thanks in advance.

Welcome to the forum.
No, there's no way to root 4.4.4 that I know of yet, you have to install 4.4.2, root it, flash a 4.4.4 that won't kill your data, then it should be rooted.
http://forum.xda-developers.com/note-3-att/general/n900aucucnc2-odin-files-t2838117 are the 4.4.2 (NC2) files. I don't have a link to the 4.4.4 files handy, but I'm sure they're in the development subforum. (You want the 4 separate files, not the all-in-one, so your data doesn't get overwritten - in both cases.) Get into 4.4.2, root with https://towelroot.com/ then go back to 4.4.4 (if you want - I'm still running 4.4.2, so I don't have to reflash kernels to get into SafeStrap; Mobile Odin doesn't work on the Note 3 yet, and I don't want to carry a laptop around in my pocket).
I think.
I went round and round with different ROMs all last week, reflashing 4.4.2 after each one, rooting, installing SafeStrap, restoring my data, etc., etc., until I can't remember exactly what the exact steps are, but I think I got it right.
And there are a few threads her on how to root 4.4.4 - with downgrading to 4.4.2, or just flashing the 4.4.2 kernel, or something.
But no, you can't directly root 4.4.4 yet.
As for tethering, see if there's a tethering app that will work without rooting, or just go to Settings/Connections and enable Tethering and see if that works. If it does, there's no reason to go through all the trouble of rooting (which is terrifying the first time you do it - and boring by the 10th).

Thanks for the info! I'll give it a try once I get home. Unfortunatly there's no way to tether on an unrooted unless at&t allows it (that I know of). And at&t cant allow it since I don't have them as a carrier right now. I've trid a couple apps from the appstore already and they either try to carrier verify or it's just a widget of the phones tethering function. I don't particularly care about flashing custom roms so if there's a way to tether in my situation then I'd love to try.

sm-G900A towelroot help

looking around i can not find anywhere that exactly states what versions of android and on what devices towelroot supports. My question specifically being for the S5 SM-G900A att phone. I am right now on lollipop and i realise i have to downgrade, but I only want to downgrade as little as possible to get towelroot to work. (the end goal being root access of course)
On another note I have two other questions i will ask here so as to not clutter the forum.
1. is there anyway to downgrade my android version without wiping all my data?
if not, any advice on backing up all my data before it gets wiped? mainly my photos, apps, and appdata.
2. I see the only custom recovery i can use is safestrap, i have read is some places that it can not backup your user data (videos, photos, etc.) and nowhere mention it does. question being if this is true and if so how can i back up all my data? i really like the idea of just doing weekly rom backups and being able to restore all my apps and all my data with very little lost (less then a week is good enough for me).

If you took the OTA update to 5.0 their is currently no way to safely downgrade and root.
Towel root only worked on 4.4.2 kernel.
Safestrap no longer works in 5.0 either.
Just have to hang tight till someone figures out root for stock 5.0.
Thank you for the help, i did not realize it was for 4.4.2 only. (why no list of working versions) as well you say no safe way to downgrade.....are there options or is it impossible? I just got the phone recently and I wasn't the one to update it, I got it second hand and well i can't control what has happened to it before me. sadly it was updated to 5.0
I may attempt a unsafe downgrade if possible, it really depends on what risk levels and if it's risk of doing something wrong and bricking or if there is a risk out of your hands and it may or may not work. else i will just wait and not update my phone in the time being.

The above post is the unbrick/downgrade thread for the g900a.
You'll notice it says not to attempt if you've taken the OC4 ota...I'd read through their first. At this point it looks pretty risky.
Good luck either way you go!

[q] [may 29]sgs5 at&t is rooting possible? Answer i am about to explode.

It is about time I get some straight-forward answers. I'm tired of Googling everything I can and it not being what I think it is.
It is about time I get some straight-forward answers. I'm tired of Googling everything I can and it not being what I think it is.
What I have come to you for, XDA, is some light in the cave.
WILL THERE BE A WAY TO ROOT THE AT&T SAMSUNG GALAXY S5 VARIANT?!
Towelroot doesn't work. And if quite frankly tired ****less of all the posts that still exist talking about it.
Is there anything in development? All I can see now is SafeStrap and Multi-Tool but if you aren't rooted these do nothing. I just want some information for God's sake. Will ANYONE tell me what is being done about the development of the device's rooting? Is anyone even trying anymore? And if so, tell me! More importantly, if there are people, why aren't they being talked about? With as many S5's as there are out there (at least to me since I know about 10 people who use them regularly) why wouldn't anyone be trying?
PLEASE people get it together!
I have come from only 3 devices, but I was able to root and mod all of them. Rooting and Modding is love and life to me and is pretty much all I sincerely love about Android. The fact that I can't afford a new phone at this stage is sad, and I have grown tired of the bloating of TouchWiz, especially with the Lollipop update. I know that a rooted S5 would be extremely awesome, but since there is nothing about it being worked on I suppose I'll just have to live with the rubbish they call TouchWiz.
And if by some chance someone who can develop something like this reads this thread, please, respond, PM me, do SOMETHING. TELL THE XDA WORLD, because I GUARANTEE there are more of me out there who have longed for this but have just lived with it. BE A GAME CHANGER A DO SOMETHING ABOUT IT.
Don't give me the, "Knox and bootloaders are hard to pass by, especially with the new more secure versions." Because guess what, geohot did it once. Not like it lasted, but the fact is is that it worked at one point. It may be harder now, but it's still possible. PLEASE DO SOMETHING. PLEASE TRY.
Anyway, best of luck to all of the users. And anyone who has read this please leave a comment and tell me what you know. Many days I'm left alone, commentless with my threads. This is one I truly need to be acknowledged.
THANK YOU FOR YOUR TIME
Well that's a big thread revealing nothing about your device other than its an s5. There are ways to root with towel root unless you have the 5.0 ota.

Towel root has worked and still does on nce. If you were on OA1 towel root wouldn't work unless you downgraded to use it then go back to OA1. And no it don't work on 5.0. There are multiple kernels and builds that att has put out that it didn't work on without downgrading. But just for future reference is always helpful if you include your build, version, etc. Like i said there are multiple builds that it didn't work on unless you downgraded is only the 5.0 that you can't downgrade.

I said that I have Lollipop so everything you're saying won't help. Plus I know you wouldn't have known anyway but I have tried all of this way before Lollipop. I tried downgrading from OA1 at the time to NCE and I ended up in a bootloop. The kernel was faulty. I had to reset my phone in a very long, aggravating process to get it back. I NEVER want to go down that road again. And like I said in the entire post, I'm just looking for a pioneer to try again and make a geohot move on Lollipop. And no offense to you, you wouldn't have known this about me anyway, but your kind of information was exactly what I was trying to steer away from. And here it comes, right back at me. I'm just tired and sick of all the people who just do, essentially, a copy/paste of common information. When in my circumstance, am looking for something difference. Again, no harm to you, but anyone and everyone that has ever responded to my threads because it's all the same.
As someone who used to reverse engineer software, updates to said software usually patch those exploits. It's not usually easy to regain a new exploit and can take massive amounts of time. I can't speak for other devs but (at the time I did this stuff and still currently) I have a demanding full time job and a family, which come first over a hobby. I can guarantee I will never buy another Samsung phone again because of this. I know it's not always feasible, but maybe look into getting an HTC phone with developer options that is unlocked from the factory. Venting on here will get your cause nowhere.

Right, first things first. Calm down and please stop being so rude and angry when other members who are trying to help you. It's not their fault you are not able to root your phone. It is possible and I'm testament to this.
You need to understand the process of how to do it and you need patients. I live in the UK with an AT&T handset and my handset was never going to ever get to 5.0 because of that fact. I am now on 5.0 and it's rooted and I found out how to do it all on this forum. Further more if you search for my one and only post (yes I'm making you do some work - it's how to teach people to learn new things) I have information in there that shows you how to get to 100% rooted 5.0. What I'm prepared to do is write for you a line by line process in a Word document that will get you from your stock unrooted 5.0 handset to 5.0 rooted. You need the right files and ODIN - that's all you need to complete this. No matter what state you end up getting you handset into bootloop, failed starts..etc as long as you are able to get into download mode you are able to recover the handset. Yes, it can be annoying and yes it can take hours to get back to square one (sometimes) but you have to be prepared for that when you do something like this. It took me two whole evenings and 5 failed attempts before I got it working.
So after reading all this, if you are prepared to accept my help let me know and I will write the document for you.
Besides the fact there are already a metric ass ton of threads in this phone's forum discussing rooting the 900A.
I've been reading them for weeks now after I was overzealous and took the OTA to OC4 figuring there was a root solution already..... There wasn't, and oh well... My fault for not researching first, but it's making me keep my Note 2 until something comes up.
Hell something may already be out, but with rants like yours..... Feel free to enjoy the great advice in the links in my signature.

Ok, so I'm sorry if i've got this wrong, but as the user above stated, I too have been scouring the web and FDA searching for a way to root an at&t galaxy s5 with an OTA u5.0 lollipop update. From all the research i have done, I have found no resolution to the locked bootloader. Are you saying that you can root the stock, unrooted, locked bootloader, sm-g900a running lollipop 5.0? If so, I will gladly donate to your Paypal for detailed instructions on how to do this! I am no noob at rooting, having rooted every galaxy since the skyrocket,. But this lollipop crap is driving me crazy. Any help is greatly appreciate!!

if you're able to root OC4 on a G900A, i'm all ears.
so far i'm unable to install TWRP (fail auth) using odin and it seems it only works for 900F or other models, not 900A specifically that has never been previously rooted. all posts on the topic suggests you cannot downgrade from OC4 and any attempt is futile at the moment.

Hi, I'm trying to make time to create the document to show how I did it. I intend to recreate the process again on my handset and include screenshots as I go through.
Basically the only way I could get my handset to 5.0 root was to take the handset back to NCE stock firmware (by the way I have all the files on my laptop to do this) using ODIN v3.09. This took my back to G900AUCU1ANCE (4.4.2) April 2014 release. I installed Towelroot, busybox and Safestrap. Did a backup of the device (when I went back to 4.4.2 I then configured my device to look and feel how I wanted it to be because I wanted to restore the data partition once on Lollipop - but this is a required part of the upgrade). You need to use Safestrap to create a backup folder structure on the SD card so you can dump the 5.0 (OC4) rooted backup on to restore later in the upgrade process. I then installed G900AUCU2ANG3 (4.4.2) September 2014 release using Safestrap. I then installed the G900AUCU2AOA1 (4.4.4) February 2015 release and then used Safestrap to take another backup. Then I did an advanced wipe in Safestrap (excluding the SD card) and restored the OC4 rooted backup (I found online I also have this file). Once that restored I then within Safestrap selected the reboot > download mode (don't restart the handset into Lollipop before doing this process - the whole process will fail). Once the handset rebooted into Download mode I connected the handset to ODIN v.3.10.6 and installed the G900A_OC4_Stock_Partitions_wOA1_BL.tar.md5 (using the AP option in ODIN). Once that completed the handset rebooted and after 5-10 mins started to upgrade files. Once that finished the handset was on 5.0 - the same as the screenshot you've posted and it's rooted. I have SuperSU installed working fine and I used Root Checker Basic to confirm the device is rooted. More so I then went on to sideload the G900A_OC4_TetherAddOn so I could get native wifi tethering because AT&T still had this locked down in the root 5.0 I installed above.
anyone verify this?
Not sure they started out on 5.0...I don't know of anyone who has successfully downgraded once on OC4.

Basically the only way I could get my handset to 5.0 root was to take the handset back to NCE stock firmware (by the way I have all the files on my laptop to do this) using ODIN v3.09. This took my back to G900AUCU1ANCE (4.4.2) April 2014 release. I installed Towelroot, busybox and Safestrap. Did a backup of the device (when I went back to 4.4.2 I then configured my device to look and feel how I wanted it to be because I wanted to restore the data partition once on Lollipop - but this is a required part of the upgrade). You need to use Safestrap to create a backup folder structure on the SD card so you can dump the 5.0 (OC4) rooted backup on to restore later in the upgrade process. I then installed G900AUCU2ANG3 (4.4.2) September 2014 release using Safestrap. I then installed the G900AUCU2AOA1 (4.4.4) February 2015 release and then used Safestrap to take another backup. Then I did an advanced wipe in Safestrap (excluding the SD card) and restored the OC4 rooted backup (I found online I also have this file). Once that restored I then within Safestrap selected the reboot > download mode (don't restart the handset into Lollipop before doing this process - the whole process will fail). Once the handset rebooted into Download mode I connected the handset to ODIN v.3.10.6 and installed the G900A_OC4_Stock_Partitions_wOA1_BL.tar.md5 (using the AP option in ODIN). Once that completed the handset rebooted and after 5-10 mins started to upgrade files. Once that finished the handset was on 5.0 - the same as the screenshot you've posted and it's rooted. I have SuperSU installed working fine and I used Root Checker Basic to confirm the device is rooted. More so I then went on to sideload the G900A_OC4_TetherAddOn so I could get native wifi tethering because AT&T still had this locked down in the root 5.0 I installed above.

This is funny.......there seems to be a huge disconnect between this and the actual issue in the OP which is someone that took the 5.0 OTA and wants root access. There currently is no way for him to gain root access. Instead you quoted, almost verbatim, my origina KeepRoot method and files: http://forum.xda-developers.com/showpost.php?p=59996087&postcount=4

Morning, first of all if you take a look at my first post you will see I have clearly stated your name and I have not tried to take credit for your process. Secondly I have only been replying to questions from members who have read my results and have then from my post asked how I did it. I have then simply explained again in the post you have replied to how I got to a rooted version of Lollipop.
Are ypu saying that if a handset takes the ota it is not possible to go back to NCE and then forward right through to rooted Lollipop or are just annoyed thinking I am trying to take credit for your work. I'm happy to guide a member step by step through a process if they want me to but I have already said it's not my discovery.

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.

HI Bober10113! Thanks for your reply. I was able to find my way there, but It seems the csc feature files are encrypted now. I'm still looking through the threads for something about how to decrypt/encrypt them, but I haven't found anything yet.

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?

Ah sorry, nevermind... I was able to make a ps1 for it instead. I'm good one decoding and encoding the XMLs now.

if you need it , you have an automatic encode/decode feature here in post 5 : https://forum.xda-developers.com/galaxy-note-9/how-to/n960f-n960n-n960u-n960u1-n960w-n9600-t3833721

you made the exe with freeware(advance bat to exe converter)that only works on your PC. read the software policy.. its clearly written that what you compile only works on 1 computer.
anyways for everyone else, here is a proper tool:

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.
all credits to tkkg1994.

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!
