Need help flashing Samsung Galaxy Note 20 to U1 - Samsung Galaxy Note 20 Questions & Answers

Not sure if this is the right place to post this, or where the right place would be, but I need help! I bought a Galaxy Note 20 (not Ultra) from AT&T on an installment plan, and I am trying to flash the U1 firmware to get the software benefits of Unlocked devices (less bloat). I'm unsure on where to start flashing to U1. I downloaded the USC firmware from SamMobile and flashed it with Odin, AP to AP, BL to BL, CP to CP, HOME_CSC to CSC, I read on an XDA thread this was the way to do it and not lose data. (I don't honestly mind if I lose my files and stuff at this point.) When my phone rebooted, it was still on AT&T's firmware with their splash screen, bloat, managed updates, etc. What should I do to flash it to U1?
UPDATE: It works now! Instead of flashing the U firmware (model ending in U), I had to flash the U1 firmware (model ending in U1)

Trying to enable smart call on Sprint Galaxy s9+

I have a Sprint Galaxy s9+(SM-G965u) non-rooted. My phone's current software version is G965USQU5CSF3. I was trying to find away to enable small call as it is missing in the phones dialer app settings. I was wondering if I could flash international firmware on a Sprint Galaxy s9+.
Google searches show that it looks like smart call was disabled by Sprint, so there isn't a way to turn it on. You could try flashing the appropriate G965U1 firmware which should let you use it.
The G965U1 (non carrier branded s9+) firmware can be flashed using the patched Odin. Make sure to use the other CSC file (not the home_csc) when flashing. This will wipe all your stuff from the phone, so you will have to set it all back up.
One thing to note when flashing firmware make sure you are using firmware with a bootloader equal too or higher then what is currently installed on your phone. Failure to do so will cause the process to fail. Also flashing the G965U1 firmware may cause certain carrier specific features to not work. This is because those specific features are not included in the G96U1 firmware and can not be added manually to the firmware files.
As for the international firmware or what you can flash it depends. You can not flash firmware for any other model on this phone.. In other words for example you can flash G965U with G965U1 (and vice versa) because they are the same model. Also (as an example) you can not flash firmware for G965F onto the G965U (or vice versa) or G9650 onto the G965U because they are not the same model.

Thank you for the reply. I do greatly appreciate it

N970U and N970U1 Firmware Links Here

For those who aren't already aware, N970U is the model number of all of the US carrier versions of the Note 10. The N970U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.
This is not a "beginner's guide to Odin flashing" type post/thread, so I won't list basic, step-by-step instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware, I recommend you consult one of the "beginner's" posts/threads - there are tons of them here on XDA.
Happy flashing!
U firmware: https://www.androidfilehost.com/?w=files&flid=297977
U1 firmware: https://www.androidfilehost.com/?w=files&flid=297978
NOTES:
- DON'T QUOTE THE OP WHEN YOU REPLY, kthx
- I have an identical thread for the Note 10+
- My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc
- My naming method for folders on AFH is: build - bootloader - Android version
So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.
- HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data
- I know AFH servers/mirrors can be wonky sometimes, so if you want to download the latest version of whatever firmware you're seeking yourself, you can do so via SamFirm or Frija (plenty of links and threads here on XDA). I pay for a subscription to a site that gets beta builds and also gets the official releases (usually) before they hit SamFirm, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single update version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm.
- You can get USERDATAs from SamFirm for everything but AT&T and Cricket- those files will never be on SamFirm. So I'll try to always upload at least one USERDATA per bootloader increment for those carriers, and I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.
- For USERDATAS (all the others are self explanatory):
AIO = Cricket
CCT = Xfinity Mobile (Comcast)
CHA - Spectrum Mobile (Charter)
TMK = Metro PCS
- the correct procedure for switching from one carrier's firmware to another is:
1. Flash full U1 firmware package including non HOME CSC
2. Upon boot, insert a SIM of the carrier whose firmware you want
3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want
Firmware is now available via SamFirm and Frija, but manual entry is required in a lot more cases than previous models. Hopefully that's just because the phone technically doesn't release until Friday, and that they change that on Friday or soon after.
Manual entry is currently required for VZW, CHA, and TMB U firmware, and for all carriers/regions/CSCs of U1 firmware

Thanks for the links. I wonder if my Note10 tomorrow will get a software update out of the box.

I only saw the news about the Verizon models getting updated. Theoretically that means that Xfinity and Charter should also have updates, since they all get the same updates at the same time. Not sure about any other models yet

By the way, I did use manual entry in SamFirm to find TMB firmware and download it. As a rule of thumb, I usually don't flash my phones right away after getting it, as I want to make sure that it isn't defective
Wonder if we need another Odin version or the regular 3.13/or Patched would work

Cool, my PC is ready and setup for Note10 Any idea if XAA firmware and the carrier's firmware are within the range/build date to allowing flashing? As I know the downgrade usually fails.

You can't downgrade if there's only one software version that's been released so far - there's nothing to downgrade to.
But even if it's months or years down the road, the flash will only fail if you're trying to downgrade bootloaders. As long as you operate within the same bootloader, you can flash anything you want
This is the one I'm getting direct from Samsung: SM-N970UZSAXAA. It is supposed to be unlocked. I asked for a Sprint sim Card. I hope it's not tied to Sprint, but can be moved to any US Carrier if I want to once the TMB-SPR merger completes.
SamFirm shows this firmware for TMB: N970USQU1ASH4 and I checked U1(XAA) as well and they are the same

Looks like everything is back to normal, in SamFirm. Manual entry is now only required for VZW U firmware, as has traditionally been the case. Also, if you type in an older version for VZW, it will automatically give you the newest version, if there is one. So you don't have to always know the exact newest version - entering in the correct details of any previous version should always trigger the newest one.
Also, SH4 is now showing as the newest build for U1, T-Mobile, and Verizon. Spectrum gets SH5 (no idea why), and Sprint is still back on SGO.

Received my Note 10 U1, tested it on original firmware XAA(build: ASGO) and just now completed flashing to T-MO without updating to ASH4 build and want the phone to find and update firmware to see if OTA works. To get to download mode, I needed to press Vol + and - and power and the same time.
Flashed 5 files: BL, AP, CP, regular CSC and USERDATA. Device shows T-Mobile logo at boot, has Advanced Messaging, Video Call and I don't see any bloatware except for couple of T-Mo apps.
Went through setup and was able to get new OTA with August 1 patch(screenshot)
Wow great job! Can I get the link for the 10+ ...

You can go to my profile to find all of my threads. But flashing U probably won't give you wifi calling. It's been extensively discussed in my S10 threads, and it usually doesn't work if you have a U1 model

Quick question, did your provider codes change? I flashed the Verizon files and am still stuck on XAA? Any help would be appreciated.

Initially, before I put in TMB sim, phone was on XAA/XAA/XAA. Now after all was said and done, my phone shows TMB/TMB/XAA. Make sure you put in the sim when you get the phone and when it has original firmware, so it can apply sim carrier's settings. Then you can flash and get the results that you need.

Thanks man I'll give that a shot.
@iBowToAndroid It states in the op that these models are all interchangeable. I have a U1 and flashed it to vzw U now when I try to Flash back to U1 it fails and says model mismatch???? Any help would be appreciated.

That's not much information.
1. What's the current U build?
2. Which U1 build are you trying to flash?
3. Where do you get that error exactly?
4. What Odin version are you using?
5. Do you get any other errors, either in Odin or on the phone itself?

Sorry, the phone was purchased as a unlocked version from samsung, model number SM-N970UZSAXAA/SM-970U1 is what the box says.
1. N970USQU1AHS4 is the build that I was able to flash. And the actual problem is that I had a brain fart and didn't read your simple instructions and instead of booting the phone first I opened the box and flashed the firmware. The issue I am having is my "Service provider SW ver. is stuck at XAA/XAA/XAA and I'm trying to get it to switch to VZW.
2. N970U1UEU1ASH4 I looked at all the n970u1 firmwares on samfirm and this was the only one that had XAA.
3. After I load the files into their locations and hit start it checks the files and the fails on the 4th step, I can run it again and find out exactly if you'd like.
4. 3.13.1 patched I believe.
5. None
I may be taking the wrong route to answer my problem. I really need help with getting it to show the right service provider code VZW.
Thank you for your help.

need instruction on career switching

hi i have a verizon tab s6 sm-t867v(lte version) the stock rom does not let you use phone app to do calls and messages app dont work. all the calls or messages should go throug the verizon propritory messages+ app ,where you need to add verizon number. . and the tablet is unlocked to any career. . I DONT WANT TO ROOT THE DEVICE. i did a career switch for my note 8 from att to tmobile without rooting so i thought i can do the same to tab s6. i have few questions
1. is there a way i can swap for another career rom
2. can i flash international rom just throug odin so that i dont deal with verizon bloatware.
can any one point me to the files and the thread.
is there a way i can use calling and texting on without going throug messages+ app. thanks for the help in advance. i am sorry if anythin i ask is silly. peace

Yes you can switch the firmware on the sm-t867v from Verizon to TMobile or Sprint. It keeps the bootloader locked down so root is still impossible but since you are not looking to root it just switching the firmware version should work just fine. I personally have metro pcs and their $15 unlimited tablet data plan on mine and I switched my firmware to TMobile so I could pick up the LTE bands it would not connect to with the Verizon firmware. All you need to do is download the modified Odin 3.14 and the firmware of the carrier you wish to switch to. It HAS to have the same base model. For example I went from the SM-T867V firmware and flashed the SM-T867U firmware to the device. So your firmware choice absolutely MUST have the SM-T867 in the beginning of it. Any other firmware will most likely brick your device if Odin even allows it to flash. The thing that makes the difference between Verizon and TMobile is the user userdata file. You must flash it with the rest of the firmware files, So BL, AP, CP, CSC, and Userdata. Don't worry, the stock firmware will come with the userdata file. Also its best that you don't flash the CSC-Home file but flash the regular CSC file as the home one will not delete your data and its probably best to do a full wipe when switching firmwares, so make sure you back up anything you don't wish to lose. When the flashing is finished it will boot and instead of the white screen with big red circle for Verizon you will get a pink TMobile screen and it will be model SM-T867U now. All OTA updates will still work without problem and you will get a functional dial pad which works for all the secret menus and all that fun stuff. BTW, I take absolutely no responsibility if for some reason it messes up or bricks your tab s6 lte. Goodluck and enjoy your non Verizon tablet.

I'm glad it worked for you without any major issues. This was the first thread I've given any real instruction on. Hope your tab continues to work perfectly. I broke the screen on mine so the only thing it's really used for is an android PC. Thank God for the Tab S6`s ability to output video so easily and the Samsung DEX software.

SM-T978U Odin Firmware Flash

Purchased a sim unlocked SM-T978U (Verizon Tab S7+ 5G) and am trying to flash the unlocked or Tmobile stock firmware to it. I've gotten "passed" flashes everything when flashing all of the files from the corresponding stock firmwares, but everything it boots back into the Verizon firmware. Any suggestions as to what I'm doing wrong that would cause this? I've probably flashed this thing 20 times at this point.
its a verizon tablet so thats normal.. u need to change csc is all
Thought that was part of flashing it with the patched version of Odin with a different CSC version of the firmware, but I've not done this before. Any suggestions or resources you can point to on how to do this? Thanks!

patched odin only removes hash checks.. all the firmware has multi csc (all the usa csc) so simply flashing firmware doesnt change csc
Gotcha, so change the CSC first, then flash the matching firmware? What's the best method for changing the CSC on the S7+? This process? https://www.**********.com/how-to-change-csc-in-samsung-galaxy-phones/
Any suggestions on how to change the CSC? I've hit a wall and haven't been able to find a way to change it and then flash the desired firmware.

You need to flash with odin, wipe, then pop the other carrier sim in, on reboot it will boot with that carrier sw.

Ok, so SIM out, Odin flash with the TMB firmware. Then, what do you mean "wipe?" Is that just choosing the CSC file in Odin so that it resets all data, or some step after to wipe it?
So I tried again with these steps and had the same result, back into the Verizon firmware.
Removed Tmobile Sim
Odin flash TMB firmware
Tablet reboots automatically into VZW firmware
Then booted into recovery mode and performed a factory reset and cache wipe
Reinserted Sim and reboot
Tablet still boots into VZW firmware
I also tried this same process but with the unlocked "USC" firmware with the same results.
Am I supposed to somehow prevent the first boot after odin flash to perform the factory reset? I've tried that unsuccessfully but maybe I have the timing off or something.

dunno wat ur flashing but all the firmware is the same.. theyre all multi csc.. so simply flashing different firmwares wont change csc lol
I don't know if this will help but on some samsung phones you can change the csc by opening the dailer and typing "*#272*IMEI number#"
edit: IMEI must me copied from the about tablet section in the settings. Press on the IMEI for a second and it will be copied to clipboard. Typing the IMEI will not likely not work.
After entering this in the dailer a menu pops up and you can select csc. Note this will usually factory reset the device.
Yes if you try this, please let me know if it works. I have the T878u 5g from Tmobile.
Any update on this? I purchased an SM-T978U (on Samsung website that is t-mobile S7+)
I expected it to not be carrier or network locked but it was locked to the t-mobile network.
Would love to flash an unlocked firmware but I can't find SM-T978U firmware, let alone U1 firmware...... I realize that flashing U1 firmware won't unlock the network but T-mobile support tells me the device can't possibly be truly carrier locked because the IMEI isn't even in their system. So I thought maybe the carrier lock is in their app tied to the system instead of the actual device??
Anyway has anyone found the firmware for these devices? Sammobile doesn't seem to list SM-T978 as a device
These devices don't have a dialer so entering the IMEI method mentioned above won't work unless there is a trick?
Guys, for cross flashing, you must factory reset from within the OS before you flash. the newer security measures will not allow the device to accept even a full flash if the device is activation locked to an account. that is likely why you are flashing and still getting the vzw stuff to come up.
@elliwigy , though the devices are all loaded with multiple csc's, and you can change them on demand (if you know how), that will not automatically load the carrier branded bloatware that comes with each firmware, and certain settings that may, or may not, be enabled or disabled by the carrier. An example being native video calling that the verizon firmware has and the unlocked firmware does not.
I almost always flash my Verizon devices with the U1 XAA unlocked software. Among other things, this lets me get security patches faster, as i get them when sammy releases them, not when vzw gets around to it. I say almost always because there are still a few devices, like my tab s6, that are vzw models with some minor hardware changes that prevent it. But in the case of my Tab S7+ and my Note20Ultra, they are both rocking U1 XAA firmware.

An example being native video calling that the verizon firmware has and the unlocked firmware does not.
I almost always flash my Verizon devices with the U1 XAA unlocked software. Among other things, this lets me get security patches faster, as i get them when sammy releases them, not when vzw gets around to it. I say almost always because there are still a few devices, like my tab s6, that are vzw models with some minor hardware changes that prevent it. But in the case of my Tab S7+ and my Note20Ultra, they are both rocking U1 XAA firmware.

Where is this U1 XAA firmware to download? Specifically for the SM-T978U?
RE: jmwfl2000 -I always untick the "Auto-Reboot" box when flashing new TWRP images to prevent stock recovery from being reapplied.After the first boot all should be well.

I'm pretty stumped like OP. Where are you finding U1 XAA for Tab S7+? Doesn't seem to turn up anywhere. Would definitely appreciate it if you could provide a link. Thanks.
I tried resetting before flashing and unchecked the auto-reboot but mine still returns to Tmobile. I just want the call and text on other devices feature.
Edit: I go the feature to work without flashing a new firmware but I am still looking for U1 XAA for the tab if anyone found it.

Purchased a sim unlocked SM-T978U (Verizon Tab S7+ 5G) and am trying to flash the unlocked or Tmobile stock firmware to it. I've gotten "passed" flashes everything when flashing all of the files from the corresponding stock firmwares, but everything it boots back into the Verizon firmware. Any suggestions as to what I'm doing wrong that would cause this? I've probably flashed this thing 20 times at this point.

I bought an unlocked Verizon Tab S7, probably same seller. Its brand new, stil has plastic on it. Are you wanting to unlock Tmobile 5G bands?

canadian 5g to US

To convert my canadian F707W to US unlocked F707U1 is download firmware for both phones put canadian AP BL and CP in normal places in patched odin I then took the csc from US unlocked version and flashed in csc in odin with canadian firmware flashed perfectly. I did a factory reset let it boot and set up Took a minute to get cell service but is working great now . dont think will be able to do updates ota but a lot less bloat compared to normal
