Hi all,
Just want to make sure I am doing this correctly and ask a few questions on the way. I have ordered an unlocked Note 10+ direct from Samsung because I really wanted Aura Blue (plus totally bonkers pre-BF discounts). My understanding is that, as I use T-Mobile, the radios are not going to be optimized for T-Mobile's network, leading to crappier call quality, and some features will not work.
1. Is this correct?
If so, my understanding is that I can use Odin to flash the T-Mobile firmware without rooting or unlocking the bootloader, and this will allow the phone to work as though I purchased it from T-Mobile. Assuming that I have this right so far, I need to download and install Odin, download the most recent T-Mobile firmware from here: https://www.sammobile.com/samsung/galaxy-note-10-plus/firmware/SM-N975U/TMB/
and install according to the instructions on the page for "5 Files" (https://www.sammobile.com/samsung/g...e/SM-N975U/TMB/download/N975USQS2ASJ8/299552/).
2. So far so good? Do I have this right so far?
3. Sometimes my wifi gets wonky and file downloads get corrupted. Is there a way to ensure the integrity of the file before I install it onto my phone?
4. I understand that there will be a lot of Samsung and T-Mobile Bloatware. To remove this, I just follow these instructions via ADB, is that right?

or these: https://android.gadgethacks.com/how-to/disable-bloatware-for-free-your-galaxy-note-10-10-0207598/
5. Anything I'm missing?
Thanks in advance for the help. I haven't used these programs since my Galaxy S3 so I'm quite rusty.
The directions look pretty accurate, but there's a few other things you will need to do.
Don't use the home_csc when flashing the Tmobile firmware to the device. Also you will want to place the userdata file into the correct spot on the odin flashing tool. The userdata contains all the carrier specific stuff.
Do a factory data reset before you flash the Tmobile firmware (to remove the FRP lock). After flashing the Tmobile firmware be sure to do another factory data reset to ensure things (OTA, etc) work properly.
As for the download you could try using samfirm and having it check the CRC32. Checking the CRC will double check the file integrity. I don't have samfirm anymore on my PC because I upgraded to the Note 10+, but someone else may have a link to a download (or you can google search it to locate it.. Which is what I did to obtain the app before).
As for the bloat I just uninstalled what apps I could that I didn't need, and for the others I used an app from Google Play Store to disable them. I do suggest that you try disabling apps first and not trying to remove them. If you remove the wrong app you will undoubtedly encounter issues/problems.

Okay, so use CSC_*** rather than HOME_CSC? Will Odin tell me about how to place the userdata into the correct spot?

Will I still need to do the factory data reset if I basically take it out of the box, make sure it works, and then flash it? Can't hurt, I guess, I just want to be clear about my timeframe on installation.

Gotcha. Do you recall which app you used? I guess I could just hide them in a launcher app, too, but I am particularly miffed about the fact that Facebook apparently comes pre-installed and can't be uninstalled on the unlocked N10+ (though I do not have one in my hands and obviously can't confirm myself as a result).
Thanks!

Yes use the CSC_*** and not the HOME_CSC when flashing.
For the userdata you should see it when you look at the Odin interface. Essentially as you place the 5 individual parts into each appropriate spot in Odin, you should see the 6th spot labled userdata.

If you just take it out of the box, turn it on and do not add a Google Account to it then you can just skip the factory data reset.
If you just take it out of the box, turn it on and add a google account to it then you will want to factory data reset it before flashing it with the carrier firmware.

I use CCSWE App Manager for disabling apps I don't want to use. It's a paid app, but it doesn't cost that much if I recall correctly (think a few bucks... It's been a while since I bought it).

@scottusa2008 Can you clarify this for me? In SM-N975U1 and SM-975U both have T mobile(TMB).
1. Can you explain why are we flash use file from U version instead of U1?
2. Do I download the latest version of the file?
3. If I want to flash back to original for return or warranty which file do I need?
I need to confirm these information so I purchase the phone tommorow

My responses in this thread pertained to the OP asking about flashing U firmware onto his/her U1 model phone. Even if "both" have it (and I used both) I only got the full functionality available from the carrier when I flashed the carrier firmware.
Otherwise I got generic one size fits all functionality with the U1 firmware... Which was fairly decent, but the U firmware was a better performer for Tmobile IMHO.
But flash what you want and see what changes. If you did research onto the subject then you should be aware of the bootloader version (explained further below).

Not sure why this is still a problem to understand? It's been answered before and even on different threads/forums if you search for knowledge. Or go ahead and try it to find out... Either way here's how I understand it (and from past experience).
Unless things have drastically changed (which I have not heard have or seen) firmware for the U1 model is unbranded firmware. It's has a carrier bloat free experience, configured to obtain updates through samsung with a generic one size fits all carrier compatibility pending on what sim card is installed. Once installed the phone configures itself based on what sim card settings are present and (from poking around on my last rooted phone and from what I can remember) some configuration scripts on the phone (enabling/disabling bands and etc). This is why some features won't work and some will, but again it depends on the carrier and what the carrier requires.
Unlike the U1 firmware the U firmware is carrier specific and contains customizations/tweaks for said carrier by that carrier. The firmware also will contain changes made by the carrier and any carrier specific apps.

2. Do I download the latest version of the file?
Click to expand...

If your going to flash firmware then you flash either the U1 firmware or the U firmware. You shouldn't mix and match firmware parts.. Just pay attention to the bootloader version of the firmware. You can only flash firmware that has a bootloader version equal too or greater then that of what is currently on the phone.

I'd like to start off by apologizing if there's a thread that has answered this. I've spent nearly a week trying to find my answer because, I'm one of those that doesn't like duplicate post to begin with or those who don't google however, I can't find my definite answer and I just want to reassure before going and spending money.
Scenario: I recently have been given an AT&T Galaxy S9 and I'm mad in love with it (using an iPhone X at the moment lol) and I need it to work on Verizon. Of course my first step will be unlocking the device to be able to be used on different networks and I do by putting in the code that I received and it does unlock it. I proceed to put my sim card in it and I notice I can't seem to get service to work. I noticed giving my Note 8 Verizon to my friend who has AT&T, he could put his sim card in and it'll restart with all AT&T functions including the boot logo and all. My S9 AT&T rejects it still. I did try and tinker with the dial codes (*#*#4636#*#*) and setting my bands to LTE/CDMA. Doing this allowed me to receive 4G LTE on the device but, no cellular service. With that being said, I've read on threads that firmwares from certain manufacturers disable bands so I assume AT&T has those disabled that work for Verizon. My next step was trying to get a verizon firmware to work on it. I downloaded the ARG8 U firmware from verizon for it and it still boots AT&T firmware regardless. My last thought would be waiting for the updated V3 U1 Firmware for the S9 and maybe that'll fix it? I just need some opinions on this matter because, if I can't get this to work then I'm going to proceed on buying a new one unlocked.
Thank you guys in advanced and again, if there's already answers for this then I apologize. I've worked with android since the HTC Hero days and I still get stumped on some things haha.

Or VZW U1
https://updato.com/firmware-archive-select-model?record=E2DA06D078D411E89F15FA163EE8F90B
For proper functionality, make sure there's a "userdata" file when you unzip.
Also, use CSC file which wipes the phone, not home csc file which keeps data intact.
If things don't work.. keep sim inside and do a factory reset with sim. it'll ensure proper CSC selection.

See the issue is those links you posted are meant for the V2 bootloader. G960UOYN(2)ARF4 . I've actually tried the U1 and all from V2 but, it gives back that binary fail due to me being on the V3 bootloader. I'll try with the V3 bootloader files for verizon again and do the whole factor reset afterwards. Unfortunately there hasn't been a V3 U1 yet for the S9. Thank you for helping me figure this out, i'll post my results shortly.

Updating from earlier, I tried with the Verizon U3ARG8 file and all it did was add on the bloatware from verizon. I've tried factory resetting and all and it still doesn't want to swap over. Every time it boots, it begins with the AT&T boot logo and proceeds to not give me proper service. I can mess with the LTE bands and get data working, just not service itself.

In S8, there's a method using Combination rom (factory binary) to do a proper carrier switch. Take a look and try. Not sure if that would work, but that's an option.

Just tried it, once you get in the factory binary, you're supposed to type *#243203855# in the dialer and be able to switch it there however, it's not allowing me to do so. All it does is clear what I've typed.

Got it, however, since it's the Canada one, it only allows me to change the CSC to companies from Canada. It doesn't allow me to type the code in factory binary but, it does in stock rom with the XAC CSC flashed. I tried the adb shell where you use the echo function but, I get the common problem others do "/system/bin/sh: can't create /efs/imei/mps_code.dat: Permission denied".
Seems though we are getting closer and closer, never seen something so stubborn haha. Sucks there isn't a U3 XAA yet.

Flashing process
Factory binary,
Do reboot to bootloader via ADB,
Flash Canada "Home CSC" (not plain CSC)
Dial *#243203855# via IME button
Choose XAC, let it restart,
On adb shell, Type in
echo "VZW" > /efs/imei/mps_code.dat

Meant to reply back but, after flashing the hell out of the phone, it somehow went into XAA CSC and I factory reset it and afterwards it allowed me to connect to Verizon. Thank you so much!
Hi,
Im also trying to convert a VZM S9 to a Canadian CSC. Do the above steps work? because after i flash the factory bin, boot into it, when i try to flash the home_csc from the canadian fw, it always fails, no matter which odin i try. also that IME code, is it only supposed to work once the canadian home_csc as been flashed? because if i try that code in the IME section of the factory bin, i get nothing!
Have a very weird problem, and think it is because of any app...
I use a galaxy tab s4 lte as a phone, it is a fully functional phone oversized... it is great, and im using tablets as phone 3 or 4 years ago... first was galaxy tab s2 lte, then s3, and now s4
S2 worked great... S3 worked great but from march of this year, randomly phone disconects fron network just to receive calls.... sms, 4g and wifi always work, but canr receive calls till i make a call... it is like it disconnects from network... i notice that, because i have (from the times of s2) my phone forwarding calls to my wife's phone when my phone is turned off or im in a plane for example...
But with tab s3, from march, i was in home with my wife and someone that call me ringed directly to my wife phone... as if my phone was turned off...a lot of times saw that... but when i place a call... it start receiving calls again...
Went to tmobile, changed the sim and same problem...
Bought a new S4 lte ($1000) and from the day 1 same problem...
Any help? Im pretty sure it could be any app... but dont know where to start
Factory reset, then install your apps, one at the time until it happens again. It's long process but unless someone came across it it's the only way to find out which app causes it. Perhaps not the only way. Have you tried to replicate it? Reboot your tablet, then ring it to check if it receives it. If not, you can uninstall one app, reboot, call, uninstall , repeat until you find which app it is. It's likely quicker this way but you need to be able to replicate it.
Most likely is the VoLTE is not set up right. And sounds like fallback to 3G for voice is not happening. Try locking it on to 3G and leave it in standby. Check whether inbound calls are coming through when you are camped on 3G.
It is possible to edit your CSC file to get it working properly. but you'll need to know all the correct fields to change and will require you to root, install custom recovery etc.
I haven't thought about that. Try that first. I mean locking to 3G.

Sounds good... but would hate if this was the problem, dont want to root phone... anyway... s3 was working ok till march... one year worked great! Because of that i think it can be a setting or app... there is any way yo change volte? I have seen something like that in any menu but cant find now
Seeing about volte... i remember on s2, and on s3 im not quiete sure, the hd call icon, related to volte, bit now have not that option in phone app settings
Thanks
I don't think the tabs4 t835n makes calls over lte, only 3g as per the specs on the samsung site. Mine always reverts to 3g when making voice calls. It still sounds great but this is the way it makes or receives calls.
Continuous Talk Time (3G WCDMA) (Hours)
Up to 50
That being said, it would be great to find out if it is capable and since there is root now, take the settings from the note9 and push it to the tabs4 T835n.

I'm not sure it's possible without root access. You could try extracting the correct csc file for s9 and flash it via ODIN.
If you have root access you can peruse your csc file using this app:

Maybe you can ask your carrier to disable VoLTE for your account?
You will be trying at your own risk when you try to flash alternate CSC, remember you can always flash back to original.
You could also try flashing a complete firmware from a different country, check firmware available on Sammobile, search by your model code. TAB s4

3 Great ideas!... ask your carrier seem to be the best if they cooperate... flash csc is the second best because have not to reset phone.... and flashing a complete firmware from a different country is a great idea too but have to reinstall everything...

You could also try flashing a complete firmware from a different country, check firmware available on Sammobile, search by your model code. TAB s4

Its me again friend... sorry for bothering you so much!
Look... here is the think...
I have downloaded two full firmwares...
the T835NKOU1ARGH_T835NKOO1ARGH_KOO for the T835N (the only firmware sammobile has for T835N)
the T835CZHU1ARH3_T835CTGY1ARH3_TGY.zip for the T835C (the latest firmware sammobile has for T835N)
When i extracted the CSC from that two firmwares i saw they are differents sizes! T835C is more than double than T835N...
Look at the picture attached...
T835N CSC File
CSC_OMC_KOO_T835NKOO1ARGH_CL13953229_QB19044239_REV00_user_low_ship_MULTI_CERT.tar.md5
47MB
T835C CSC File
CSC_OMC_TGY_T835CTGY1ARH3_CL14074605_QB19357398_REV00_user_low_ship_MULTI_CERT.tar.md5
112MB
What do you think about this? would be safe to flash a file, from other device with double the size...
It is the only thing i can do (talking about flashing other CSC) because on Sammobile there is only one complete firmware for the T835N... is not like other phones that you can choose country... the only country is korea
Thanks in advance....

One question... do i need to root before flashing CSC? or can flash it just as a complete firmware just using CSC slot?
Thanks

I believe if you flash only the HOME_CSC it will preserve your data.
You don't need root
First up though, I would strongly recommend you try to back up your data using Samsung Smartswitch (back up to SD card). And try to back up to Samsung Cloud (not sure if this still is a thing). So you can restore when things go pear shaped
I believe the chances of getting VoLTE working faultlessly on your Korean tab are pretty close to 0. But if that's what you want, I would first try flashing a known working CSC from a device with same android version on YOUR carrier (Note 9 maybe?). This is unlikely to work, I think Samsung has been encrypting CSC files recently. You may need to flash Korean firmware at this point.
Secondly, I'd try flashing an alternate csc_home package from another country. Try the one you've downloaded. If you search T835 on sammobile there are many countries listed. I'd try XSA Australia if the first one doesn't do what you want.
You're on your own my friend.
If all this is getting too hard, just leave your tab locked to 3g in it's current state.

I dont want to getting work VoLTE... i want to switch off buttt... not setting phone in 3G... setting it in 3G implies i will not be able to make good whatsapp video calls... skype calls... stream tv... ando... or at least nos to foas as stayong in LTE but with VoLTE turned off

Friend for the T835N (the phone i own) on Sammobile there are only 1 firmware... for th T835C there are 3... these two devices are LTE... but for the T835 you see a lot... but they are only wifi... do you say a wifi device from XSA australia will have CSC file? Im confused

Would hate have a great 4G device stuck in 3G... in the last case will root it and edit the CSC with the app you send me but im not sure root is working ok because had not time to read the tutorial and will be a pain in the a** start from zero with more tha 200 apps... a lot of passwords and more than 70gb of data (i own the 256gb model)
Again friend thanks for your help is really helpfull
I have an unlocked Samsung Galaxy Note 8 that was a Verizon Wireless variant. I went to swap the SIM cards from the Total Wireless SIM to active AT&T SIM card just to see if it would work and it did but I went to put the Total Wireless SIM card back in and I'm left with all of this AT&T bloat ware that won't let me uninstall along with the AT&T globe as boot logo... Any ideas?

You have to flash the unlocked firmware that's N950U1 because that doesn't have the bloatware like that.
I'm confused. The phone is not rooted it's just been carrier unlocked. It acts like bloatware and it wasn't there before I don't understand how a SIM card inserting it and replacing it with a different carriers what causes it to leave behind un-installable applications and a boot logo

Because it caused your CSC to change and the carriers love putting all their crappy bloatware in the phone because they want you to use their products.. Root has nothing to do with it. If you flash the unlocked firmware N950U1 you won't have to deal with that again!

It's pretty easy actually.. You just download odin that's the application you flash with then you download the firmware you want to flash then unzip the downloaded firmware so you can see all the files in it.. Make sure the computer already has the cellphones drivers already installed or it won't see the phone connected then open odin and put each file in their respective places AP to AP BL to BL etc... Then flash. If you end up with an error just ask us.

Ok ive got all of it downloaded and unzipped and files added to all the corresponding boxes, my phone is recognized and in download mode.. Yet it still fails to start the process. Ive got the latest odin and im assuming it must be the firmware version?
Just out of curiosity, did you try doing a cache wipe and factory reset in recovery mode with the Total Wireless SIM card installed. Honestly dont know if that would work but might be worth a try.
Also with Odin, did you try to run as administrator? And assuming you are using a Windows based computer, what version of Windows are you using? And I believe there are also 2 versions of the latest Odin, 1 regular and 1 that is modded. Maybe try the other version as well. I dont have a link but I'm sure someone may come along and provide it.
I was trying to keep all of my info so I didn't do a wipe. In the odin version that I have on been using is the one on the Samsung firmware website.
I'm pretty sure this is the patched one here: https://forum.xda-developers.com/android/software/patched-odin-3-13-1-t3762572
Also if you use Samsung Smart Switch, that is an easy way to save pretty much all your data, customizations, and most of your programs right to your SD card. It will restore pretty much everything for you. It makes things a lot easier to restore when playing with different ROMs or versions of Android. When you use Smart Switch to restore, it will basically look and feel like it was before you wiped.

You're using the wrong odin you need to use the patched version or it will continue to fail.. I've attached the patched version of odin here.

Something isn't right.. Try a different USB port and a different wire!! Also make sure you right click on odin and run it as administrator.. Go through the firmware files that you extracted and delete just the .md5 part off of all of the files you're going to flash.

Pop the sim card tray out and then push it back in with the phone on and see if it sees it and asks to restart.. If it doesn't then I'm not sure and someone else will need to chime in.

A third-party seller on eBay but it was brand new never been opened or activated.
But I think that would be irrelevant since it was working just fine with the exception of some bloatware.
Im wanting to de-Cricket my S9
Its a G960U, so i assume that all i would really need to do is flash the U1 firmware, correct?
and if that is correct, it will give me a Sammy splash screen and boot animation too, yes? Perhaps some sophomoric questions, but im just making sure.

Yep that's right, it will remove all the carrier crap (I assume splash, definitely boot), just remember about the bootloader/baseband versions that cannot be downgraded so if you flash to version 4 you can only flash v4 or above after that
You will also receive updates direct from Samsung instead of the carrier

damnit. thats just my luck too :/ thank you for affirming my understanding of how this works. I came to the S9 recently but i do recall the odin flash process for the t-mobile S2's that required the individual files to be placed in Odin before flashing, so this is all old hat as far as the process goes. Any idea on how long it might be before the U1 firmwares are going to be available for V5?

Only Samsung knows, but a lot of firmwares are now on v5 so if I had to guess I'd say the next update probably will bump it up to v5, they said the security updates included in the June update required it to be updated
When it receives the next update is anyone's guess though
And yes, all 4 parts of the firmware to be flashed together in the corresponding ODIN sections, HOME_CSC will not reset the phone, CSC will reset it, use one or the other in the CSC section

I live in Canada. I purchased an S20 Ultra off a seller on Canadian best buy (open box). I assumed it'd be a Canadian variant, but it was an unlocked US version (U1 firmware). OK whatever, but it meant my Samsung Pay doesn't work, along with a few other calling features.
I downloaded the patched Odin, downloaded the G988W firmware (with XAC CSC) with Frija, added the appropriate files to Odin (used Home CSC), and flashed it. The flashing itself went fine, but when I went to re-insert my SIM...nothing. It didn't even error out and say "No SIM Detected", I just had no coverage, and in SIM manager, both slots were empty.
Freaked out, and eventually flashed back to G988U1/XAA and thank Christ it works now. But my question is...why?
I dug though this forum before doing it to try and anticipate any issues. Followed the instructions to the letter, nowhere said this would be an issue. Couldn't even find any relevant support questions for this issue on this model. Not sure if it's a new development, but I absolutely don't want to risk messing my phone up further if I reattempt.
Bonus question: My CSC info is: XAA/XAA,XAA/SPR. Does that mean that it was originally a Sprint model phone, someone's flashed the firmware to an unbranded version, then sold it off as New (Open Box)?
You can't just flash a firmware from a different phone. The hardware is different, so the way to communicate with it is different. You're lucky it even booted, I wouldn't have expected that even. You're simply stuck with the original firmware and CSC list. Or, maybe you could try with custom ROMS but I wouldn't be so sure about it. Either way, you'll have to use a ROM/firmware that is built for your phone (G988U1).

Huh I thought the actual hardware between U1 and W was the same? They're both Snapdragons. Besides I've seen other posts of people doing the same (tbh, they were going from W to U1, but still)

Probably. Very common for online sellers to do.
The key probably lies in what the CSC shows as after flashing W firmware. If it stays as XAA, changing the CSC manually to a Canadian one could possibly make it work

Any thoughts on why my flash caused the SIM issue? Did I maybe just install the wrong version? I don't think I did, I used Frija
Some further research led me to the subject of accidentally mucking up the modem firmware which I might have done

Samsung Pay doesn't work - that's a big one for me, it's a pain in the **** losing that. Will only accept US ZIP codes when setting up.
Caller ID doesn't work
That extra info you get when texting (like seen/read stuff) doesn't work in the native Samsung text app, you have to use google messages (yeah, no)
I'm sure there's other stuff but those are the main ones
