I just upgraded my phone to the S22 Ultra from ATT. It's an ATT phone with FirstNet Sim.
It hasn't even been powered on and set up for the first time yet.
I want to flash the U1 firmware to it, to debloat the phone, get to Google RCS and away from ATT RCS, and unlock features that ATT locked out.
Is this possible? If so how?
I do have an unactivated ATT Sim (blue/white) that came with my phone that they let me keep.
What unlock features
debloat after any updates downloaded
Debloat LISTS - S22 Ultra Series
Hey everyone, figure i start a thread on apps/etc that can be safely disabled, so that we can dial on on removing needless junk from our phones. I am currently running a Snapdragon S22 Ultra, SM-S908U 512GB (AT&T variant) so my list may vary...

You can just disable or uninstall the apps that you don't want. I think it's only about 5 At&t apps.

I was looking to buy the Galaxy Note 8, and is it worth buying the Unlocked version over the ATT version? I know I will save a little money, and also have less bloatware. I could not find much info on the basebands of these phones, there would not really be any basebands the unlocked version wouldnt have that the ATT version has? I assume that it would just be smarter to get the unlocked version?
Someone correct me if I am wrong
Sorry this is somewhat unrelated to the S8+
Thanks
Somebody mentioned the carrier specific ones may get updates more frequently. Regardless, the only unlock that really matters to me is bootloader unlock. US Snapdragon S8/S8+ are not bootloader unlocked--regardless whether the model is carrier unlocked or not. Only the Chinese and Hong Kong Snapdragon S8/S8+ bootloaders can be unlocked so far. My recommendation is to pre-order the Note 8 as you were interested in that phone, but that if you were planning on sticking with the same carrier and wanted updates more frequently, getting a carrier specific Note 8 might be best.
I'm in the same situation. I currently with att prepaid, they have LTE+ (LTE advanced). I did speed test twice, getting 127mb down, 30mb up, 115mb down, 28mb up. I'm not sure if unlocked version note8 has all the LTE bands. I thinking of just getting att version and if I want to switch carrier in the future, I just pay for those unlock service.

Be careful about those assumptions, make sure the AT&T variant has all the bands needed for full rate.
Recently switched from ATT to Verizon, and ended up getting a new phone (not *really* complaining since it's the GS8+) because my 1 yr old GS7edge AT&T model didn't have support for the correct LTE bands to work properly with the Verizon network.
I'm planning on staying with the same carrier, I just figure I'd get update faster, have less bloat ware, and have more lte bands (with the unlocked version)
Isn't that all accurate?
ALL the US versions have the same exact hardware and support the same exact bands. The ONLY difference is the carrier specific firmware. And you can change that by flashing whichever firmware you want through ODIN.

I have both S8 T-mobile and S8 unlocked. They have identical LTE bands. Moreover, when inserting SIM cards from different providers the CSC is changed to that provider and some specific options are enabled. I put in T-mobile SIM card and used it without any issues. Put in Vodaphone Europe SIM card and CSC changed from TMB to XAA (unlocked) and phone still had all LTE bands available and worked. I'm sure it's the same for ATT. Also, from previous experience if you get ATT version and change providers you'll not get updates anymore unless you go to Samsung to have your phone updated, as all OTA's go through ATT servers.
Go for unlocked.
The problem you are having is because the firmware on the unlocked phones doesn't allow for WiFi calling, Visual Voicemail and other carrier programmed services. To fix this, if you have a Samsung S8 or S8+, go to your closest BestBuy with a Samsung service center which is 95% of them and tell them you would like to flash your unlocked phone to the carrier you want. Then that firmware will unlock those services. When you are done and want to sell your unlocked phone, take it back and have it flashed back to stock firmware. These days, unlocked carrier specific phones don't have a ton of carrier bloatware anyway.
Hope this helps many here

Just wondering if the regular unlocked version supports mmwave or if I have to buy through Verizon. This gets on my nerves now.
Unlocked should in theory work with all carriers unless a carrier does certain odd things that couldn't be included on the "catch all" unlocked devices.
From what I can see it should work with Verizon phone and data just fine. Only the Verizon model it looks like comes with UWB (Ultra Wideband) though since that's Verizon's way of doing things if that interests you.
If you want that, will mean that you will have to have carrier injected junk though and buy the carrier version, get updates from the carrier, and have to have it unlocked by the carrier or sell it if you switch carriers. It will probably need to be unlocked by the carrier to put a custom rom on there also if you wanted to go that way. Its win and lose.
Coming from someone who just got the Verizon variant, it is indeed loaded with bloatware. It is also completely locked down from flashing roms or unlocking, verizon removed the oem unlock option entirely from their variant. So you can't even Odin flash to the unlocked firmware. Also the unlocked in the US is $349.99 right now versus $499 from Verizon directly. Although if you really want that UWB 5G then your only option is the Verizon model. Though imo not worth it. Go for the $349 one and enjoy it.

So I got the 349 one and it works with 5G was pleasantly surprised when I saw the 5G appear on my cell. All reps said phone compatible and the 5G Sim etc etc
Transferring device was painless.
I love the phone. I'm coming from using an Axon 7 never had a samsung phone before but like it. Got rid of a lot of samsung crop but customized it the way I like.
Thanks for your reply!
This is US market specific. For the A53 5G, any of the US carrier versions (with the exception of Tracfone) SIM unlocked will work on any of the big 3 carriers. Most of the versions (including Verizon owned Visible) are A536U, which is the version with Sub-6. A536V is the Verizon version with mmWave. I don't know what A536D from Tracfone is. Yes, you can get Sub-6 5G on Verizon.
But if you want to bootloader unlock, whether you are directly purchasing from Samsung or any SIM locked versions from carrier, it is not possible. See https://forum.xda-developers.com/t/psa-there-is-no-oem-unlock-on-us-galaxy-a53s.4443189/
I can confirm that the unlocked US version purchased from Samsung DOES work with Verizon. And like b1283822 said, does have/support Sub-6 5G, no UW.
I've been on Verizon for about 10 months now, but would like go switch to AT&T. I put an AT&T Prepaid SIM into the Verizon S22, and was expecting it to restart with the AT&T CSC firmware, but it stayed with the Verizon software. I even got a message saying that because it wasn't a Verizon SIM that some services would be unavailable.
What's going on? I thought all the US S22 Ultras were the same phone whether it's bought from AT&T or Verizon or any other carrier.
Are you using an esim with Verizon? If so try turning it off and letting att be the only one active and it should reboot. You will still keep all the Verizon apps and logo
Nope, I'm using a physical Verizon SIM. Isn't stuff like the boot animation and 5G icons supposed to change, since it's a different carrier?

Can happen if the firmware you're on doesn't support "BYOD" yet. This is true of earlier releases of phones on U firmware. U1 supports it out of the box, so you might want to consider flashing U1.
Right but this is a Verizon S22 Ultra. It isn't really early I would think. Aren't all the S22's in the US the exact same phone?

Same hardware but like I said U firmware is hit and miss.
I switched from Verizon to T-Mobile. After 2 weeks I was still running Big Red branding. One day I started having issues with cell service and data. I flashed the latest U1 software and have been problem free ever since.
Hi, I bought an ultra American s22 I'm from Mexico when I bought it it was unlocked, the Verizon transfer was even made and now that he wants to put another Mexican chip since the Verizon chip was almost 50 dollars a month, it's a lot but the version doesn't work for me let me tell me to contact verizon but verizon says that there is nothing wrong that they get unlocked and everything in their system I have even taken it and everything and I have not been able to do anything currently I have the version SM-S908U verizon. something I can do or a ROM that can change it?
