[Samsung Galaxy Note 10+ Guides, News, & Discussion] SCitta:
I use Phone Info app to check my Active CSC code, it is XAA

It does not allow me to update via OTA, I can only do it manually with ODIN.

The *#272*IMEI# method does not work for me either.

Anyone knows how to get my phone switch to TMB which can receive updates via OTA ?

New T-Mobile Galaxy Note 10+ 5G update as of right now.

With September security patch and one UI 2.5!
[Samsung Galaxy Note 10+ Guides, News, & Discussion] iBowToAndroid:
I realized I've been slacking on this model lately so AT&T USERDATA for bootloader 2 (build ending in TE3) has been added. T-Mobile also got this version and someone else has already uploaded their full firmware package to AFH, so you can grab that if needed.

And full AT&T firmware (all Odin files, since T-Mobile did not get this version) was added for bootloader 3 (build ending in TG4)

Hi Everyone,

Hoping someone can point me in the right direction.

I have a Metro branded Note10+ 5G (SM-N976U with CSC code TMK). The phone is SIM unlocked and I'm using it on T-Mobile without any issues. However, I'd like to change the CSC to TMB.

So far, I've tried 3 things:

1) *#272*IMEI# doesn't work. I ran the same on my TMO branded 10+ 5G and the menu to change CSC comes right up. It's annoying that they locked it down on the Metro (TMK) version.

2) The CSC changer tool posted earlier in the thread. I can install the "theme" file but I don't actually get the option to change CSC under "Legal information" as it should. I also didn't wanna play around with that tool too much since it was flagged for a virus.

3) I downloaded the latest firmware for the TMB version of 10+ 5G (N976USQU3CTJ2) and flashed all five files with patched version of ODIN. Everything seems to flash fine but phone stays as TMK. I tried the flash both with and without the T-Mobile SIM card inserted. No difference.

Is SamKey the only option left? I tried to read up on it but hardly any information on the tool and the whole buying credits thing seems to be an annoying hoop to jump through...I'd rather just have in-app purchase type of a setup. Anyways....someone posted earlier in the thread about having success with this option so I assume it would work. Just would like to get some info on how to go about it.

Thanks!

Thanks for posting the link it totally saved my life with my current SM-N976U AT&T model, had a very hard time trying to locate a compatible firmware for my phone.

I went onto AT&T website and saw they updated to this now with patch:

[Samsung Galaxy Note 10+ Guides, News, & Discussion] 1.61803:
Thanks to @iBowToAndroid for saving my day for the complete guide, really appreciate your hardwork in sharing AFH, with your guide I successfully upgraded my firmware to DUB1, I would like share the problem I faced and fixed during the upgrade.

My region is in Malaysia, I bought this SM-N976U AT&T carrier online.

1) I use *#272*imei# to change CSC from ATT to XAA, because I hate bloatware, change to XAA will remove all AT&T preloaded app, people warn using *#272* imei code, but it is okay since my region is in Malaysia.

2) After changed CSC ATT to XAA, no network/mobile signal, and can't change back to ATT anymore because *#272*imei# will not work when CSC is XAA. I did factory reset however network still not working, no mobile signal.

3) I flash firmware UA3 with [Odin3_v3.14.4], added AP, BL, CP, HOME_CSC and Userdata from AFH (AndrioFileHost AT&T version), intended to reset back to original AT&T version to get signal back, however it still showing samsung boot screen instead of AT&T, flash firmware won't change the CSC, that's why ATT not showing in bootscreen, only [samkey] is able change CSC, but still mobile signal not working.

4) Then I try [Reset all network settings] and [Reset all settings], mobile signal and LTE back to normal. so this fixed the connection issue.

For UA3 to DUB1 update, I am confuse whether to use TMK or TMB (T-Mobile) since there is no ATT version for DUB1,

5) I downloaded both TMK and TMB zip file, and compare CRC using 7zip (cyclic redundancy check) any modification of file will trigger different CRC code, found out that AP, BL, CP, CSC and HOME_CSC having identical CRC Code between TMK and TMB, except for USERDATA is different, thus, based on this logic, ATT will have all file same except for USERDATA, so either TMK or TMB is fine for firmware update

When I do Odin Firmware flashing I excluded USERDATA and only added AP, BL, CP and HOME_CSC and it success upgrade to DUB1 and everything working well.

answer to @action8 update firmware won't trigger locked status for samsung KNOX nor change Warranty Void counter.

Lesson learned, don't buy carrier phone from other region, in future look for unlocked/unbranded phone, this will make our life easier.

Bootloader 5 files have been added for AT&T - build UC2. T- Mobile might get this update too, but i'm not sure yet
[Samsung Galaxy Note 10+ Guides, News, & Discussion] LakebayBob:
Good Morning iBowToAndroid!

First and foremost, thanks for all the hard work and effort you have put into this, including posting the AT&T files. It is really appreciated and it's clear you have a passon for this.

I've tried to follow your instructions, but it appears I'm getting something wrong, I was hoping you might point me in the right direction.

I have a TMO SM-N976U. I moved to a location where TMO service is terrible. I'm using an AT&T sim now, and basic phone functions work, but of course the carrier functions do not. I followed your instructions (I believe properly, but I'm clearly not an expert).

I put the phone in developer mode, turned on USB debug and apps over USB. Downloaded Odin and your Android 11 AT&T firmware files UA3 - 11.0 which based on your naming I assumed to be the latest Android 11 files. I had backed up the phone completely and successfully used Odin to flash the phone. I did flash the userdata along with BL, AP, CP, & CSC. After reboot I had to enter my Google account password to get FRP, no issue. When reloading the backup from Samsung Switch, the phone took about 3 hour to download an update while in Switch. Then, the phone reset, I successfully reloaded the backup and after reset, still a TMobile splash screen.

I would love to hear your thoughts, and I appreciate all the help you give everyone!
[Samsung Galaxy Note 10+ Guides, News, & Discussion] iBowToAndroid:
After the first original flash, did it show T-Mo splash screen, or AT&T?
[Samsung Galaxy Note 10+ Guides, News, & Discussion] LakebayBob:

Just want to share my experience in this. Bought an ATT N976U from the US and using in Malaysia. Phone came with XAA/XAA/ATT and never received OTA updates.

Downloaded Google phone app and changed CSC to TMB/TMB/ATT using *#*#27262826#*#*

Voila. Received the OTA updates one by one since May2020. Am now on N976USQU5EUC2.

Volte is also working on Celcom.

Did not have to flash firmware. Data not wiped. Everything seemed to be working normal apart from "Tips and Help" in settings crashes every time I click it. Also phone boots with T-Mobile logo now.

I have a N976u ATT unlocked, June 1st sec. patch running Android 11, and I’m trying to switch it to T-Mobile. Nothing changes when I flash T-Mobile‘s files . It still shows up as ATT and none of these dialer codes work. I get “connection error or invalid MMI” after it says USSD Code running at the bottom of the screen when I type them. I’m trying to flash the July TMB build since it matches BLs.
[Samsung Galaxy Note 10+ Guides, News, & Discussion] iBowToAndroid:
I'm assuming that you've already tried inserting a T-Mo SIM to see if it converts on its own?

If so (and if it did NOT do the conversion automatically), are you flashing TMB USERDATA also?

[Samsung Galaxy Note 10+ Guides, News, & Discussion] iBowToAndroid:
No, the OP doesn't say that anywhere. You must be misunderstanding.

The Verizon model has a different model number, so crossflashing isn't possible

Having issues switching carrier firmware from T-mobile to AT&T. Flashed all 5 files in the ULC - 12.0 folder (BL, AP, CP, CSC, and USERDATA), but still end up with a T-mobile firmware. Interestingly the baseband version now matches the AT&T firmware, but the phone is still treated as a T-mobile device.
[Samsung Galaxy Note 10+ Guides, News, & Discussion] iBowToAndroid:
Before flashing, did you try inserting an AT&T SIM to see if the phone would perform the conversion on its own?
[Samsung Galaxy Note 10+ Guides, News, & Discussion] mattxx3:
I actually had the AT&T sim inside for over 2 months already, so no conversion. The phone is a T-mobile device that is unlocked and worked perfectly with AT&T until they took down the 3G network a few weeks ago. Now I can't receive or make any phone calls, but texting and mobile data work. Apparently this has been happening with a lot of people, not just the Note 10. Keep being told on reddit that the best solution is to flash the device to an AT&T firmware, but so far haven't had any success.
