Hi, I want to convert my unlocked Note 20Ultra N986U1 to a N986U T-mobile version. Is this as simple as using Frija and searching for SM-N986U CSC TMB and flashing what it finds in Odin? File name it finds is SM-N986U_1_20211029105635_1woht6u539_fac.zip.enc4.

I did this before on my Note 10+ and it worked. Just want to make sure I am using the right search method and it is safe to do this on the Note 20 Ultra. Thanks in advance.

If you have a TMB SIM installed, download the odin and the top file in post 2, flash the BL/AP/CP/CSC (not the HOME _CSC). Backup, because it will wipe.

Edit.... You have to have an active TMB SIM installed in order for it to install the features that come with a TMB device

My phone is active on T-Mobile. I will give it a go. Thanks for the quick help!

Made the jump to A12 Beta 2... On Tmobile U1... It's nice but I miss the convenience of root...

Is it possible to get back to SAC23 custom Rom? If so then... How to reflash, back to rooted and unlocked 3.1?

Try opening Samsung members app. I will show something like welcome to beta tap on gear icon on top right and then tap OneUI beta program status. See if you can sign up from there.

Noob question. Does anyone have a more detailed list of the firmware meaning from the first post. Thanks in advance.

Specifically I wanted to know what other options are available for the CPU and their translation. If OP didn't give an example I wouldn't know SQ meant Snapdragon. Also could someone provide an explanation of what each means (Update, Security, Engineering)? I am looking to buy a used model off Ebay and see some of the builds say different things but I don't have a decoder handy.

SQ, FX etc = CPU and model specific
U,S,E = Update, Security, Engineering, respectively


And can someone give a brief description of what the next two lines mean. Most of what I see on Ebay is 2D or 1A.

1,2,3,4,5 etc = bootloader revision (This is important! You cannot go to a previous revision)
A,B,C,D = Android version

If you can give an example of what the device build number is, I could help decipher it

N986U1UES2DUH3

I've seen another model that listed S for Security. Commonly I see U for Update. What do the two mean?
Security is just that, it's typically the Monthly Security patch, Updates tend to be bigger and have system "updates" over and above the Security items.

Edit - As a side note, I'd be very careful buying a device on ebay unless you can confirm that the IMEI isn't blacklisted. There have been plenty of cases where folks have purchased on ebay and gotten an expensive brick
