Thank you for writing that post, you reminded me that many people are now doing this to get eSIM, when I wrote this post the need was to get OneUI 3 Beta (Android 11). I have updated the first post for eSIM.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rjcf82:
Hello everyone,

Great thread. It just doesn't seem to be clear if the t-mobile sim card is necessary. My phone must be carrier locked (bell, canada), but it's ok because I want to use the esim feature with 2 numbers from same carrier.

Would following this post work for me?

Thanks
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tommytep:
mine doesnt work, the esim still greyed out. i dont have T-mobile simcard. I think it works on old firware, especially if you're still on Android 10 or early 11. Hope beta Android 12 would make it for esim fan.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
It works on Android 11, however if it works without t-mobile sim or not I can't check. I suggest use t-mobile sim once the feature is activated get back to using what you have.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] waninoko:
I flashed from U1 to U

AP>AP, BL>BL, CP>CP, Home CSC < CSC, no userdata.

My version also shows TMB/TMB, TMB/XAA

Build Number: SP1A.210812.016G998USQU4BUK7 (Android 12, One UI 4)

I have all the tmobile features including RCS, eSIM, etc.

My question is, will I still get OTA updates and will they be the carrier path OTA or the Unlocked path OTA from now on?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
You should get OTA and it would be carrier path OTA.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] waninoko:
Awesome! No issue with using the HOME CSC?

Hello. I am buying the n986u1 in brazilian, and I intend to do this process to active esim, but like know if it will work in brazilian, or will I need a american SIM?

Oops, replied to wrong thread
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Ducter:
Little late and I can't say for certain but I'd believe it to work fine now. The sim requirement was for converting to the T-Mobile firmware, they've since released it officially in the beta that works for the U1.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
Is stable released for U1 Android 12?

I flashed TMB U to get dual sim, now that its avail is it worth it to switch back?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Stable is not released yet for U1 (Unlocked devices).

Personal opinion if you bought your device unlocked U1 then totally worth it to flash back to Unlocked firmware. I am using that on mine and using esim and really like the fact that I don't have bloatware.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
I bought mine unlocked U1. Are you using beta? I'm wondering if I will have any difficulty switching back and if I can keep data. I had a lot of difficulty getting the CSC to stick when switching to TMB , I had to do soe roundabout method requiring multiple flashes
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Yes I am using beta. Yeah when switching between unlocked and locked variants there will always be risk of data loss.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
Stable N986U1UES2EULI out
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Yes and links are posted on OTA thread. Sadly I had to manually flash via Odin as my phone crashed and went into bootloop due to use of Hex Installer. So I couldn't capture OTA.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
I'm a little nervous to try the flash. I don't want to lose data
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] PapaDocta:
Does the U1 with no carrier, support esim?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
It was on beta 3, i believe it should on stable.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Did you try Home_CSC. I never lost data using that. Recently I converted back from U to U1 on Android 12 bootloader 2, all went well.

Yes it does, I am using it now.

Yes it is there.

PS - edited to fix typos and grammatical errors. I must have been sleepy when I typed this.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] PapaDocta:
Thank you warriorvibhu, all went well converting from Verizon U to U1 and all working perfectly except for Google pay... Well at least now I can add many esims as I want unlike Verizon firmware
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
I updated again today stick with OTA and TMB. Maybe unrelated but one of the issues that broke noticed since A12 update is MMS with Google Messages. I get "message expired or unavailable" error. Thought it was Visible but MMS works in Samsung Messages. In fact if I receive the message while Samsung Messages is default I can switch back to Google and view it fine, but if GM is default get error and switch to SM and msg still unavailable. Tried clearing data but no luck

I thought I was already on EULI from last week but updated OTA again today and still on EULI. Maybe different build number.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] HoMachine:
Sorry iam pretty noob, stupid question, do i need to root my phone first before doing this firmware update?

1 additional question: I'm Andriod 10 right now, do i need to first upgrade to 11 then 12? or I can jump from 10 to 12?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] rskyline:
No need, make sure you follow the steps on the OP.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Markeee:
I just want to flash from U1 to U on a U1 device if I include Home CSC will it resent my phone after reading through this thread I'm still not sure ?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
If bootloader version isn't changing it won't reset. If your going from one bootloader version to another then it will reset.

Similarly of you are going from one android version to another during the conversion it will reset.

It won't reset if

You use Home_CSC and you flash U On U1 or U1 on U but android versions are same and bootloader versions are same.

Well I can't speak for Fold as I don't have one. But my information is accurate for all Note devices starting Note 8 through Note 20 and all Galaxy S Devices from S9 to S21. Those are the ones I have tested / experienced flashing U to U1 or Vice versa.

Hi, I'd like to thank you so much for this as i wasn't able to update my Samsung galaxy note 20 ultra U to android 12 wirelessly but I did from Odin and it was my first time to do such a thing but it worked , just a question cause i really afraid to do the unblock by changing the S/N from U to U1 this device i have is ATT basedband and i don't know what version i have of the boatloader but i think it's version 2 can i proceed to flash the u1 version or it will be a risk on my device and thanks in advance
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Your device will be fine, also I advise flashing same bootloader version as your current one. You can check your bootloader version in settings - - about phone - - software info.. Just look at your baseband version and the 4th number from right is your bootloader... See the attached pic... Bootloader version is 2.. Also don't get confused by the version as this is a screenshot from S22
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] shwQi:
thank you so much i did it with Odin and it has been unlocked i think! , actually i don't know if it has completely unlocked or this is just a custom Room and the device itself is still locked for ATT but the good thing is i received about 4 updates over the WIFI and it wasn't before my phone was stucked at android 11 with one ui 3.5 and now it has uploaded to android 12 with one ui 4.1

am I going to receive the updates normally now ? 😅
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Yes you should receive updates normally now. For faster updates I always use Odin :)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] shwQi:
Hi, i still didn't get September update or October is it normal i i have a problem and need to do something from my side
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
I haven't had those on my T-Mobile note 20 ultra .. you can always check Frija and see what are the latest updates released. Since there is none released how will you get it. .. I think that Samsung has been a little delayed in this case.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] shwQi:
my phone was ATT locked but i think it should be unlocked after using one of those unlocked firmwares i think and i actually after booting up the unlocked firmware i think for venom i received like 6 or 8 updates a in the same time 😂

i just was worrying about not getting the rest of the updates but fortunately i received September update this day a bit weird but I'm fine with it 😅

btw, I'm thinking of upgrading to fold 2 i hope i don't face any of those issues
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
I am on unlocked firmware too and just received September security patch.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
I originally went from U1 to TMB U for eSim capability. Thinking of going back since eSim has been available across the board. Have a few questions first to double check

1. I am using Visible on VZW network as my primary carrier, will going back to U1 from TMB U affect band availability and improve service or no effect?

2. Is XAA the correct CSC to put in Frija? The latest firmware for U1 I am seeing is N986U1UES3FVI7/N986U1OYM3FVI7/N986U1UES3FVI7. My current baseband version is N986USQS3FV17,

All I should need to do is use modded Odin and use Home CSC to hopefully keep my data?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] JeffATL:
So anyway, I tried to return to XAA from TMB and somewhat failed. My phone model does say SM-N986U1 now however the Service Provider Software Version says TMB/TMB/TMB/XAA

Originally when I converted to TMB I had to do some crazy stuff where I had to flash DUE1 U firmare first, then flash the U1 CSC of DUE1 and then flash the TMB latest at the time which I think was DUH4 or something....

Anyway, I am trading in phone to Samsung. I hope they dont reject it because of CSC/software version - phone is in great condition
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] shwQi:
i don't know if have to worry right now or not but i dtill didn't get android 13 while i already did the unlock by following all the instructions above

i was on ATT locked and now i installed the unlocked firmware and the only update i got is for security update in 1/11/2022 so there is anything else I can do from my side to speed up the process of getting the new update faster?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
I don't think android 13 is released for unlocked variant yet. I didn't find it on Frija either.

Please feel free to correct me in case my info is not updated.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] KOLIOSIS:
I check my phone & SamMobile on a daily basis, still have yet to see Android 13 for SM-N986U1.

i actually not sure about the unlocked versions is the USA but in my country and others got the update

and this is confirmed from Samsung support in a call i made with'em last week

otherwise i see unlocked versions of S20 and 22 ultra got the update

i started to think that i did something wrong while flashing, idk.

I have the T-Mobile variant (which is still SIM Locked),Odin flashed to unlocked XAA firmware & it is on BL3.

The option to download an eSIM is available.

But, I'm guessing you're curious if an eSIM or regular SIM from another network will work on a SIM Locked phone.

My guess is no,but, I don't think there is any harm in trying.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] oneturn:
I'm pretty sure it won't. I think it will remain locked. I'm not trying to unlock the sim. But thanks for the info. I'll see what I can do with it.

Thanks again

Yeah, the phone will remain SIM locked, changing firmware won't do a thing regarding that, just kinda mistakenly was thinking you might be trying an eSIM from another carrier.

Hi guys,

I got myself a Note20 5G SM-N986U in asia and found out that the esim setting is missing. Read and by flashing TMobile firmware the esim can be enable. So right now there's a couple of question I still unsure about:-

My phone software now is :

One UI 5.1

Android Version 13

Baseband:N986USQS3HWB7

Build: TP1A.220624.014.N986USQS3HWB7

CSC: SAOMC_SM-986U_OYN_XAA_13_0007

XAA/XAA,XAA/VZW

Security Patch March 1, 2023

Do I have to revert back to Android 12 or 11 in order to do this? thanx
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chromeless1:
update : Ive already tried downgrade from One UI 5.1 to One UI 4 TMB firmware security patch for September 2022 (since the updated esim firmware was on B/L 2 and mine already updated to B/L 3, therefore the only option to go to would be another B/L 3 firmware that are later then the original esim April update firmware right? ), but still dont have the sim manager. I'll try to update to later firmware or maybe final update available to see if the sim manager will appear or not.

And it seems I cant update through OTA since tried it and it says Im on the latest firmware. Dont know why this happens since Ive done a clean flash (wiped data)..
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] chromeless1:
Update,

Ive tested again flashing from U to U1, and now the esim is enable and without using TMobile simcard (since Im outside of US). I am now connected through esim from a local provider here in Malaysia. So for those who live outside of US can give it a try. Thanx to warriorvibhu and others..

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Rhalium:
thanks. i managed to flash over the firmware, however one problem when the phone started up was it kept on saying "phone is starting up" with no sign of it ever improving so i had to factory reset it after Odin was done flashing the VZW firmware. It facotory resetted just fine, so it was good that i made a desktop back up using smart switch for windows. currently restoring the back up. it did have to download the october 2023 update presumably from verizon. All in all, it seems to be going good so far. Just restoring the smart switch backup now.

i did notice in this thread's initial post that it says you cannot "dirty flash" between U and U1. So after Odin finished flashing over the stuff to the n986 [u?] now. i had to factory reset it, then it downloaded an ota update from Verizon presumably, and now am currently restoring the backup from smart switch on my laptop.

keep in mind, i just wanted to flash over the verizon specific firmware to the [formerly] n986u1 just so we could use the carrier video calling between the 2 phones.

All good you can use Frija tool to download the correct firmware, otherwise give me some time I will share the link from SamFW

Update: here is the link: https://samfw.com/firmware/SM-N986U1/XAA/N986U1UES6HXC1

NOTE - - Your device CSC says XAA and device model says SM-986U which is very confusing for me I suggest you download from the above link and flash the SM-986U1 variant which is meant for XAA devices and since you are in Nigeria that is more appropriate for your device.

If you don't know how to flash without losing data please read up. I have posted a flashing guide somewhere and many others have done it too, always back up your data.
