[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] life_speed@yahoo.com:
So this didn't go well. I ran ODIN using SM-N986USQU1BTIB_CHA firmware, but after finishing the download firmware screen on the phone it said something about "resize failed" and didn't restart. When the phone booted it still had the T-Mobile splash screen, but wouldn't let me into the phone or allow me to power down for a retry of the flash procedure without entering the PIN pattern. But the previous PIN pattern no longer works, it somehow changed as part of the failed (?) flash attempt.

Attempting to use Samsung remote unlock through the samsung account doesn't work, because of course this phone isn't associated with the account anymore.

How do I recover this thing? I can't even turn it off!

Edit: I was able to get it to power off by first holding Volume Down, then holding the power button to power off. Then held both volume up/down while connecting the USB cable and starting ODIN.

After executing "factory reset" from the bootloader menu it has the correct FW now, went through setup without the SIM card installed. Put in the VZW SIM card and rebooted.

Still has T-Mobile splash screen and no wifi calling, but the lock screen in the upper left hand corner now says "Verizon". I'm going to talk with Verizon tech support tomorrow regarding the wifi calling issue. I'm not sure what the deal is with the T-Mobile splash screen not changing, maybe this is a separate operation to change?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mellojosh:
If you have a t-mobile splash screen on boot, the firmware did not change successfully or you may have flashed the HOME_CSC file in the CSC field if Odin. If you want a clean, stock phone, then re-flash the SM-N986USQU1BTIB_CHA (which is the latest Verizon U firmware) or the N986U1UES1ATID from the link in post 2 (U1 unlocked firmware). Keep in mind if you go with the U1 firmware, bloatware is removed but some things are a little different like, video calling options, and some extra steps are needed to get nationwide 5g up and running. Also, make sure when you flash whichever firmware you choose that you use the patched Odin. I use patched (modded) 3.14.1 and flash the NON home csc in the csc field. I also recommend doing a factory reset from the settings menu before flashing, then power down and boot into download mode and flash. Hope this all helps.

Kangi can move to OP when he has time as the Mega link expires at some point. Extract as normal,flash with Odin. Most of you here should already know how to do this[emoji481]
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] life_speed@yahoo.com:
Thanks for the reply. In the software update menu it displays versions N986USQU1BTIB/N986UOYN1BTIB,N986USQU1BTIB although I agree the TMB splash screen doesn't point to a completely successful flash. I used Odin3_v3.13.3b referenced in the second post, is this version not OK? I can try doing a factory reset from the settings menu before loading firmware.

I did flash the non-home CSC.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mellojosh:
The Odin listed in the first post is not the modded one. Just do a quick Google search for the 3.14.1 patched one, the mod part skips some check that occurs in the non mod one that causes a fail when changing firmwares. I would still re flash since you have this mixed bag result, but I am curious what the Service Provider SW Version shows under settings->about phone->software information.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] life_speed@yahoo.com:
N986USQU1BTIB

Thanks, will try the modded versions. I found this link on XDA Odin3_v3.14.1 by khawajagsm, but the .RAR file appears to be corrupt. I'll keep looking, it does sound important to use the correct version of the tool.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mellojosh:
The service sw version should be something like VZW/VZW/VZW. I am assuming yours might look like TMB/TMB/TMB. Since you have a tmo phone with a Verizon firmware and sim, it should read VZW/VZW/TMB
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] life_speed@yahoo.com:
Correct, it is still TMB/TMB/TMB listed in the service sw version. This is after a factory reset from the settings menu, load the VZW carrier version SM-N986USQU1BTIB_CHA using Odin3_v3.14.1_3B_PatcheD. Reboot, go through initial setup, then power off, insert VZW SIM and boot. I have to admit the SIM is quite a few years old, don't know if that will make a difference. Maybe I should try unlocked software SM-N986U1_1_20200923135305_20urjleafx_fac?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] k_otix99:
Mine is saying currently TMB/TMB/ATT should I be concerned about this at all?

TMB services seem to be working and the phone is stable

Do I need to / can I even change the last ATT to TMB?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Yes you do. This looks like a bad flash even though the phone might be working.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mellojosh:
OK...so are you SURE that the phone is SIM unlocked from t-mobile? I believe on t-mobile sold phones you have to run an app called Device Unlock or Network Unlock. It has to be done on the tmo network with the U tmo firmware before any flashing will work.

If you want to try and flash the U1 firmware without a sim installed, boot the phone, get through the setup and then insert a Verizon sim, you should get a carrier services update pop-up, and if the phone reboots and you get to VZW/VZW/TMB and data works, you're good. If you insert the sim and nothing happens or it reboots and it is still TMB/TMB/TMB then the phone is still network locked to tmo.

---------- Post added at 12:34 PM ---------- Previous post was at 12:20 PM ----------

[MENTION=401384]k_otix99[/MENTION] if your phone was originally an ATT phone but now has a TMB sim in it, this is the correct configuration. If you are using tmobile as your network and your phone has tmobile features, then you are good, as long as it is the U1 unlocked firmware. If it is the U carrier firmware, as long as you have a TMO boot screen you're good too. If you still have the ATT boot screen or settings options, I would flash a different firmware.

I think of the XXX/YYY/ZZZ configuration as follows

XXX=Sales Code-What kind of features are setup in the firmware like wifi calling, video calling and settings menus

YYY=Network Code-What kind of network features are set for things like carrier aggregation and LTE/5G bands

ZZZ=Manufactured as Code= What model the phone was originally manufactured as. Ot has no affect on the system settings or options. THIS CAN NOT CHANGE. IT SHOULD ALWAYS BE THE SAME. ONLY A ROOTED PHONE WOULD BE ABLE TO ACCESS THE FILES NECCESSARY TO CHANGE THIS.

Hope this explanation helps.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] cuibap1:
Thanks for a very detailed explanation!!! I have an unlock TMO phone (SM-N986U) showing TMB/TMB/TMB. Can I flash it with TMO U1 firmware?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
There is no TMB U1 Firmware as U1 is unlocked . An unlocked phone will change the CSC to the sim card inserted.

For ex U1 Firmware on an unlocked model will have a CSC that looks like this: AAA/BBB/XAA ------ Now when you insert TMobile Sim it changes to TMB/TMB/XAA or if you put in Sprint sim the code would be SPR/SPR/XAA.

So if you are going to change to Unlocked firmware your CSC will change to TMB/TMB/XAA, i am not sure why you would want to that as TMB is eligible for beta so there is no advantage i see and then you might lose some native tmobile features.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] cuibap1:
Thanks. This is all new to me so I just want to know which firmware I can flash my unlock TMO phone with. I used to flash custom firmware years ago but I don't know how these new stuff works. So I will stick with the carrier firmware listed in post #2 above and not bother with the ones in post #3.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Yes that is the safest option for you no need to fiddle if not necessary. Choose one from Post 2 for TMB.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] life_speed@yahoo.com:
This phone shipped with U1 firmware (screenshots attached), it was originally purchased from Costco. I thought that meant it was unlocked, but firmware flashing isn't proceeding as expected so I'm not sure what to think. That said, I do appreciate your efforts to help point me in the right direction.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mellojosh:
That is not an unlocked U1, it is definitely a Tmobile branded U phone. All samsung unlocked U1 phones will end in XAA. Also, Costco website doesn't show they sell the XAA version. It looks like you were sold the Tmobile version, which means it will be locked to the tmobile network until it is carrier unlocked through tmobile on the Tmobile U firmware.

Also, in your screenshot, the software version is U. It is listed as n986usqu1... instead of n986u1ue... the U1 indicator comes right after the N986 part.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] cuibap1:
Yes, this is TMO phone with U firmware, NOT U1.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Do not get confused, Lifespeed guy is talking about his own problems his phone is unlocked and yours is locked to Tmobile. Do not get confused. Just do as i said and you are good to go.

---------- Post added at 02:06 AM ---------- Previous post was at 02:01 AM ----------

Dude i have been following your posts. You are unnecessarily confusing yourself and others too. It doesnt matter where you bought your phone from. Keep it simple go to settling>>About Phone and look at Model number if its SM-986U which is what you have based on your screenshot you have a carrier locked phone , no matter what anyone says to you. If you go flashing other firmwares you will surely face issues.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] life_speed@yahoo.com:
I see, I misread the software version. I do not have a T-Mobile SIM or service with T-Mobile, I bought this phone used. So you're saying it is "SIM locked" to T-Mobile and I must seek T-Mobile's help to "unlock" it? I can probably enlist the original owner's help if needed as he is a T-Mobile customer.

Before attempting this SIM unlock procedure I must flash it back to the T-Mobile carrier FW, then go into the T-Mobile store and put it on their network with a SIM card? Is there a tool I can use to unlock it, maybe not much use without a T-Mobile SIM?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] cuibap1:
I wasn't talking about my phone. His phone has TMB/TMB/TMB and loaded with U firmware so it is T-Mobile phone with U firmware and not with U1 as he said in his pist
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] life_speed@yahoo.com:
Apparently so, guess that's what happens when buying used. Is there anything I can do to get this thing functioning on Verizon with wifi calling?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] warriorvibhu:
Gotcha

---------- Post added at 02:11 AM ---------- Previous post was at 02:10 AM ----------

Its tough man, I am sorry you are going through this. Its easier to convert U1 to U but changing one carrier locked to another is going to be tough considering Verizon uses a complete different type of mobile network tech.

Is Verizon sim working i mean is it Sim-Unlocked at this point ?

Also if its feasible i think it would make more sense for you to switch to Tmobile they might give you a free phone or something if you bring more than one line.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] cuibap1:
I had to call TMobile to unlock my phone. I bought it from Samsung but decided to get TMobile branded phone instead. It took them a while but it's unlocked now.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mellojosh:
[MENTION=4383116]life_speed@yahoo.com[/MENTION] if you are still on the N986USQU1ATI5 software with Tmo boot screen, don't flash anything. Work with Tmo to make sure it is SIM unlocked. But if I remember correctly you tried to flash SW before and got to SW N986USQU1BTJ2, which is a U branch for Verizon. An you confirm what your SW version is right now?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] life_speed@yahoo.com:
My understanding is the hardware in this phone is compatible with T-Mobile and Verizon, pretty sure there is no hardware issue. The tech at Verizon said there should be no problem with the T-Mobile phone, although they likely did not understand the vagaries of carrier-specific firmware revisions. The VZW sim works on 4G LTE and 5G in the phone, the only headache is wifi calling doesn't work. As far as I can tell, everything is fine otherwise.

It sounds like I just might need to "SIM unlock" this thing, whatever that means. Sorry I'm not familiar with this, appreciate the help.

---------- Post added at 01:58 PM ---------- Previous post was at 01:52 PM ----------

Correct, I'm on Verizon now, although I would think I could flash it back to T-Mobile.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mellojosh:
[MENTION=11191323]cuibap1[/MENTION] You're welcome!

You can flash U1 firmware from post 3 if you want to. You're CSC version will still be TMB/TMB/TMB, but the firmware will change things like the LTE icons at the top and remove Tmo bloatware. All unlocked models are also eligible for the UI 3 firmware, so that should still show in the members app when that is available. You can also stay on the U firmware and keep things like Tmo apps and Tmo boot screen and icons. Its your preference.

missing piece to switch T-Mobile phone to Verizon

Thanks to some quick help from [MENTION=2649928]mellojosh[/MENTION] the missing piece was:

go to the stock Samsung phone app and dial *#272*(Paste the IMEI) then hit #. Do you get a preconfig screen? If so select VZW and install. If you can chose Sales and Network code change, do that. If you can only do the Network change, do that.

The phone already had SM-N986USQU1BTIB_CHA carrier FW flashed, so correct for VZW. But inserting the VZW SIM *did not* cause it to switch carriers, extra step was required per above. However, it was still working on Verizon's network, but not fully-featured as seen from the lack of wifi calling.

It now boots up with the Verizon splash screen, wifi calling works, and it immediately ran an update enabling 5G access.

Screenshots showing versions and wifi calling:

Its unlocked firmware..just so you know. Yes it can be flashed. This topic has been covered numerous..numerous numerous times in this thread. Is you device Unlocked? The firmware you show is carrier locked and this is the unlocked firmware. But yes you can flash it. I'm At&t, on At&t if you flash unlocked firmware (U1) to (U) device you lose features like wifi calling...not sure if its same on Tmobile. In order to get it back you have to flash (U) csc in the (U1) firmware. Remember, in Odin flash BL..AP..CP..CSC or HOME_CSC to keep data instead of csc. But I think you have to factory reset when going from U to U1. I know for me I had to..others didn't. But for best results I always clean install..but thats just me..I'm kinda OCD...lol

Sorry for asking something that has probably been asked and answered 100 times already but...

I'm on a T-Mobile N20 Ultra that's TEMPORARILY network unlocked and I want to move to an unlocked build (U1). Which one is the latest (as of this posting) that will work with T-Mobile? ATJ3? I ask because there are references to carriers next to some of the build links in the first 3 posts of this thread, but other links are provided with absolutely no mention of carrier (I'm hesitant to flash/Odin anything that doesn't say TMB next to it). I'm aware that I might need to install Carrier Services from the Play Store and enable VoLTE Video, RCS, etc, via the IMS workaround. Just want to move to U1 so that I can jump into the OneUI 3.0 Beta.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] kangi26:
So the firmware isn't carrier agnostic. All of the firmware that's posted here will work on any N986U or N986U1 device. I add the different carriers tags (most of the time) for people to know if they might be able to expect OTA based on the carrier that they have service with. ATJ3 will 100% work with your device, but I cant say right now if you would be able to get OTA (I have to look into it this evening)
