As per the title, bought an unlocked G970U instead of U1 by mistake. Should I expect a Verizon splash screen greeting me in the bootloader? I don't wanna see any branding anywhere in my phone. Can I get rid of any of that flashing U1 firmware?

Which G970U phone you have bought. If it was a Verizon branded, then their logo should greet you If you bought T-Mobile variant, then its logo will be present while booting the phone. Flashing is possible and it depends which carrier you have. Also don't you have the phone in hand yet?

Yeah, the phone hasn't arrived yet. In the pictures I can see the box has no carrier logo, but I'm guessing it's Verizon because I haven't seen a Verizon branded box yet. Also, the box definitely says G970U.
I've been a Nexus/Pixel user all my flashing life, so I'm well versed in the fastboot/adb dark arts. How does this compare to Odin? There are so many new terms that I'm still trying to understand: CSC, HOME CSC, USERDATA, etc. Is there any guide I can follow to flash my incoming phone to U1 firmware?

The T-Mobile version is also G970U, so it can be pretty much any carrier. USERDATA file is present in carrier firmware, if you flash unlocked firmware you won't need/have this file.
Link below is for S8, but works for S10 as well. Of course you would need to use firmware files for your phone. I would also use instructions under "Flashing standard firmware" first using Standard Odin. If you get an error when staring to flash, then use (Patched) Prince Comsy's Odin.

Thanks a lot. One last question. I'm based in Mexico (we only get Exynos here), so I got a U version to get the Snapdragon CPU. Obviously I don't want any US carrier branding/blotware in the phone since I couldn't benefit whatsoever from it. What about OTA's, though? Will I get them whenever Samsung releases an update for U1? Or will that depend on my carrier? Should I update monthly using Odin? Do I have to factory reset? So many questions :silly:
The link you provided doesn't work, btw. But I've since found some other Odin guides. Thanks!

I corrected the link in case you need it.
To answer OTA question: I had unlocked U1 model of S8 and when I flashed it with T-Mobile firmware then my phone got OTA from T-Mobile when they release it. I assume if you have carrier branded phone and flash it with U1(XAA) firmware then most likely your phone will get updates when Samsung releases them. You won't have to use Odin every time there is an update if you flash properly. Also, it would be advisable to flash using CSC file instead of HOME CSC, so your phone would be wiped. It is because you change firmware and want your software to be fully compatible. After flashing and you check your phone's software update and see that is shows "not compatible or something similar", then I would just suggest you to do "reset"(factory reset) from setting and after you setup your phone, that message will disappear. Also don't do any software update before flashing as you phone may get a fresher firmware than the one you might be trying to flash.
1) Check your current phone firmware
2) Download firmware you want, but if you can, get the firmware that is a previous one than the current one, so you will check to see how your phone gets OTAs
3) Flash using Odin
4) After that disconnect and let the phone do its thing
5) Set it up and check to see if software update section in settings don't give you any messages such as the one I outlined above, if it does, just factory reset the phone
ok so, i have a straight talk s10 and i want to install verizon software on it. i have already tried using odin but, it still comes back as a straight talk software. i am getting no errors on odin and it says it successfully passed. what am i doing wrong??
You have to first flash SM-N975U1 (US unlocked) firmware first onto the device and then you can flash the U branded software you want. When you want to switch carrier firmware you must flash U1 firmware first.
Hey guys,
It's been a while since I've done rooted or flashed any phones, but right now I have my Galaxy S9, and I want to flash the firmware to one that is unlocked. Right now it's locked to T-Mobile.
Is there any guide on here that can help me? What firmware/ROM should I use?
Thanks!
Tom
Get the latest U1 firmware from SamMobile and use a Patched Odin to flash it. Assuming you're on Snapdragon we have no way to unlock the bootloader or root. The only reason I flashed U1 Firmware was to get the Samsung Caller ID & Spam Protection that piece of **** Verizon blocks to try to get you to pay for theirs.
I'm currently living in Japan, but will be moving back to the US in a couple months, so I recently bought a refurbished Galaxy S20 FE 5g that claimed to be unlocked from the US and had it shipped to Japan.
It works fine with my Japanese sim, but came with AT&T bloatware installed and the model number is still SM-G781U. To my understanding, an unlocked phone should have a '1' after this, signifying that it's unlocked. Because of this, I don't get OTA updated and am still stick on Android 10 and One UI 2.5. So I figured I'd learn how to flash it and do that. It says the CSC is G781UOYN1ATIG, but then when I go to Service Provider it says ATT/ATT/ATT.
Could I just flash the firmware for the SM-G781U1, CSC: XAA onto it and be able to have a fully unlocked and updated phone? Sorry I'm a bit new to this and don't want to brick my phone. Thanks!
I did the opposite (from SM-G781U1 to SM-G781U) and worked with no problems. I needed ATT Wi-Fi calling that worked only with the ATT firmware when I was on Android 10. I suggest to do a factory reset when switching between branded and unbranded but (in theory) you should keep your phone data if you flash the HOME_CSC file.
I have a verizon branded s21 ultra. Switched to tmobile and flashed the u1 firmware. Flash went fine, rebooted, put in tmobile sim, but still shows VZW/VZW/VZW. Cannot receive tmobile ota's. Model number says U1. Any help is appreciated.
It should show TMB/TMB/VZW correct?
I remember going through a similar issue on A20. The steps are probably the same https://www.droidwin.com/change-csc-codes-samsung/
Even if you can't change the CSC, you can always flash the Tmobile rom (zip) using SamFirm and install them manually https://www.xda-developers.com/download-samsung-updates-free-tools/
Tried flashing tmobile software using Odin. Booted up to verizon splash screen and still showing VZW/VZW/ VZW

SM-G998U1 isn't the model number for the TMobile Branded device, it's the Unlocked variant. You can download the TMobile firmware here. You may not receive TMobile's OTA's even after you flash TMO Firmware since your Primary CSC will always be VZW.

When I flashed the TMB firmware, it still boots to Verizon splash screen and still shows VZW/VZW/VZW even though there is a tmobile sim installed
Try changing the CSC to TMO by entering the following code on the Dialer TouchPad. *#272*YOURIMEINUMBER# In the string replace YOURIMEINUMBER with your actual IMEI Number. You may see a list of regional CSC's. Select TMO then select install. I'm not sure this method still works on the Verizon device or after the latest updates but it's worth a try.
