v2 Bootloader Firmwares XAA and Carrier

Ok for those that took the XAA update ending in K2 and tried everything to load another firmware and failed here is help. The T-Mobile firmware is currently on BQK5 which is Bootloader v2 so you can download and apply it to your device using the latest official version of ODIN. WAIT!!! Don't get your panties in a bunch, READ!! Keep your sim card in your device so that you can get your carrier firmware and logos. This works on both AT&T and T-Mobile devices. The Devices are the same so don't let the TMB fool you. It works. You can use this if you want your carrier software back and play around with the Oreo Betas. I am not trying to step on nobody toes here but I will try to keep yall updated on the betas also.
Here are the links.

You are welcome. Thanks for taking the time to say thanks.

Thanks as well. This is a huge help!! What do you think the chances are of this phone ever getting an unlocked bootlloader with custom roms? Slim to none?

955U1 Nougat to 955U TMB Oreo

So I have what was originally a VZW 955U, flashed soon after I got it, to the unlocked 955U1 firmware using Prince's Odin and have been happy so far. Now with all the Oreo updates released except for the unlocked one, I'm wondering if I can just use prince's odin again to load the latest TMB Oreo firmware or need to do the whole engboot thing first? My current software is latest Nougat build for 955U1 and shows up as TMB//VZW.
Any thoughts?

No one? I remember reading on some of the earlier threads that if you flashed U1 first, you could then flash to the other carriers versions without the other steps but want to confirm. Don't want to deal with bootloops or softbricks.

I think you need the eng file ..but there is not oreo eng file..

Tried a lot of things, flashing tmobile oreo directly using modified and unmodified odin, trying to flash the latest Nougat builds from Tmobile using Prince Odin (the Dec one almost took and showed up as TMB/TMB/VZW but ultimately would not get updates) and then flashing back to the unlocked version but nothing worked, will likely have to do a full erase and reload the unlocked version. The eng boot file no longer works far as I can tell. Will just have to wait for the unlocked version to get updated. Sucks as this is a corporate phone and my firm has been pushing to get Oreo on all devices.

If someone has a recent guide on carrier switching the S8 , would appreciate it. Most guides here are from May of 2017 and I'm betting those files are too old to be compatible if you're on the latest Dec build for 950U1/955U1. At least doing a full reset and reflash of the 955U1 brought Wifi Calling which wasn't quite working right since I had just flashed over the 955U1 software over the stock verizon last year.
I think I'll just wait a few more weeks for the 955U1 Oreo to drop. Has to happen eventually right? Lol.

Odin to CRC5 for at&t

Since all of the firmware versions now include all the settings for each carrier, can I just download any CRC5 firmware from updato for SM-G950U and flash it using the newer odin? Or is carrier switching still required? Basically I am planning to take my at&t S8 that is on the unlocked Oreo beta and go to the official CRC5 release, but on at&t (which currently doesn't have a full set of firmware to flash available).

DL any of them. You dl one, you have them all. They will all flash the same and install carrier files/bloat depending on the installed sim card

S10+ G975U want to remove ATT bloatware.

Hey there. My S10+ G975U is running G975USQS4DTF6, One UI 2.1, wanna flash unbranded.
Tried a couple tutorials from here but nothing has removed the AT&T bloatware.
Familiar with flashing, odin, combo files, etc.
It's my phone, completely accessible. I just want to remove the system hog bloatware.
'preciate it!

Just flash an G975U1 ROM and you will get rid of those bloatware

Thanks for your responce!
So have to root/unlock flash custom recovery first? If so I haven't found instructions for the US AT&T model.
Any advice much appreciated.

Tried two firmwares with odin 3.13.1, 3.13.3, 3.14.1 patched
G975USQS3CTB6_G975UOYN3CTB6_TMB
G975USQU1ASBA_G975UOYN1ASBA_USC
Always either SH256 SW and/or SW REV CHECK FAIL.

Tried another couple firmwares with odin 3.13.1, 3.13.3, 3.14.1 patched....
G975USQS3CTB6_G975UOYN3CTB6_TMB
still Always either SH256 SW and/or SW REV CHECK FAIL.
also always abl.elf, xbl.elf fail in Odin.
Should I use mount the Userdata? I think i've tried both ways and they fail. Ugh, losing track of what I've tried now.

I did this a year ago when I first got my S10+ Verizon and flashed the unlocked rom on it.
I believe that there's a modded version of oden here. Find it and download the latest original unlocked firmwear and you should be good.
No root and nothing

Downloaded the most recent through Frija for CSC "USC" and "TMO"
Tried flashing with Odin modded and regular. abd 3.14.4 now.
Still keep getting SW REV CHECK FAIL " [ab1]Fuzed 4 > Binary 3"

Also, the I've noticed sometimes HOME CSC is used or included when other times regular CSC is.
USERDATA is sometimes not used, what's up with that?
Thanks again for any more leads. I keep flashing and wishing lol

There are two very similar models: 975U and 975U1. The one ending in U1 should be unbranded.

I need to unlock bootloader?

Recently tried both:
SM-G975U_1_20200722120433_iwlnbyil7p_fac
SM-G975U_1_20200610113004_mh0r74212v_fac
Both from Frija
Is that 1 in the middle correct?

Which version number of Odin is for S10+ Android 10 i guess would help narrow down my problem too?
Besides the firnware Odin has to match too right? Or can you just use the most recent version for any earlier firmwares too?
Added screenshots from Phone Info SAM
It comes down to confirming exactly which firmware is needed, version of Odin (modded or not), which CSC to put in(CSC or HOME) and is USERDATA necessary too?
Thanks again all!!!

Most of your questions can be answered here. https://forum.xda-developers.com/s10-plus/how-to/sm-g975u-firmware-downloads-tmo-spr-att-t3908657
You can flash any Rom (V, ATT, or anty other American Rom) you want as long as you don't go backwards on your bootloader version. The version # is the 5th from the last digit on your baseband #. I flashed a U1 rom on Verizon bought S10+ and now get updates straight from Samsung with no vendor apps at all.

Winner:

Thanks for all the leads!

SamFirm does not load any info for an ATT S8+ / Does not show "USA" Region option. What do I do?

I hate ATT. I hope their stupid company dies soon.
Anyway, I'm trying to flash my ATT S8+ that is running Android 7.0 with Android Pie. I first attempted to use Frija and it said that the ATT "CSC code not supported". I then tried SamFirm and when I input the phone model SM-G955U, it doesn't show the "United States" Region option.
Ideally, I would like to flash my phone with an unbranded Android Pie. What do I do?
UPDATE: I am able to find many different firmware files on SamFrew. However, I still need to know if I can flash an unbranded XAA file from there?
Will it work? And do I need a modded version of Odin to flash? I came across some guy's youtube tutorial that says only to use a modded Odin to flash unbranded firmware on an ATT Samsung phone, but unfortunately his video is from three years ago and so I'm not sure if the modded Odin he's linked to will be compatible and be able to flash the much recent released firmware updates.
UPDATE: Issue resolved. I went ahead and flashed it and it worked.
