Could someone point to the latest XAA firmware? I for some reason always deem to get the wrong one and look at the build name and it isn't the one I thought I got

Quick question, If I'm using SamFirm to pull down firmwares, is the Model and region for the XAA version:

Model: SM-G955U1

Region: XAA
[T-Mobile Samsung Galaxy S8+ Guides, News, & Discus] stmims1124:
Correct. There are other U1 models listed, but you need to use one marked XAA

This is for the G955U1 (S8+) XAA August

---------- Post added at 05:41 AM ---------- Previous post was at 05:32 AM ----------

Does anyone know if when flashing the latest updated U1 XAA August firmware, is it possible to flash the T-Mobile's CP & CS from their latest (but older) update, which is a month behind the U1 on updates now? I know normally it should work, but T-Mobile hasn't gotten the August update yet, so I would be flashing the older July CP & CSC from TMB along with the other files coming from the more up to date U1 XAA build. Just wondering if using older CP & CSC versions with newer AP and BL may cause Odin to fail. Any input is appreciated. I may take the plunge and see what happens.
[T-Mobile Samsung Galaxy S8+ Guides, News, & Discus] stmims1124:
In case anyone is wondering, flashing the CSC and CP from the older TMB firmware after flashing all of the newest U1 XAA firmest does indeed work, but I wouldn't use the CSC. I would use just the CP for the future just so you get right radio firmware-You'll see that you have an older baseband than firmware, but whatever. The CSC also installed the TMO splash screen on my already debloated phone and it irritated me tremendously (plus, it made my phone show as TMB/TMB/TMB, even though I was on XAA). The U1 XAA firmest adjusts the CSC according to your SIM card anyway, so it's not needed.

EDIT: I've found that using just the TMB CP file with XAA firmware wouldn't allow me to receive MMS picture messages from my girlfriend, who also has a T-Mobile S8. I could receive MMSs from people on other carriers, but not from T-Mobile devices that use RCS. I ended up having to flash both TMB CP & CSC for it to function properly. Probably has something to do with T-Mobile's implementation of RCS or something.

Awesome posts, what I learned.

A lot of people had this question. So here goes. I have a Tmobile S8+, so I got it network unlocked. I wanted to use the phone with Verizon. So I installed the XAA firmware in this post, now I'm using a Tmobile S8+ I had on T-mobile with Verizon Wireless. Works great and no bloatware. Thank you guys for the research you do.
[T-Mobile Samsung Galaxy S8+ Guides, News, & Discus] kdecoteau1:
I know, it works great ? on U1 firmware , no bloatware plus LTE+. You can switch the firmware with either carriers while using there SIM card to obtain the bloatware if you want. Spirit SIM card are lock, so you wouldn't get full Sprint boot animation.

I have the s8 plus (UK varient) bought a week before they officially released. I talked to text now and was informed (As if the plug wasn't a dead giveaway) anyhow if Install this will I still get updates? And more importantly will my device stay u locked as I bought it unlocked so I can use with any carrier but am thinking because I live in United States the USA firmware would be best..please advise

Hola Eclipze, como estas?

Te escribo porque sos la unica personas a la que puedo acudir con el problema que tengo. Mi telefono es un modelo SM-G955U1, XAA. Desde el momento que lo compre me dio errores, no funcionaba el wifi, ni el bluetooth, reinicios, etc.

Intente actualizarlo con samsung smart switch a la ultima versión y aparentemente funcionó... después de ese update el celular quedo en un bootloop permanente... le meti el firmware nuevo con odin pero sigue en la misma, no se soluciona el bootloop. La versión que tengo es G955U1UES2AQL1, estuve viendo y a mucha gente le paso esto mismo en una actualizacion anterior, en este link podes ver el thread, el tema es que al intentar meter ese bootloader el celular me dice "sw rev check fail fused 2 binary 1", por lo que lei es porque el celular no me deja instalar una version mas vieja a la que actualmente posee.

No se que mas hacer, me podrias ayudar?

Unbranded rom for Oreo ?
[T-Mobile Samsung Galaxy S8+ Guides, News, & Discus] monkey39:
I had a similar issue, although not exactly the same. I was on the TMB Oreo beta and I was trying to get back to XAA Nougat (AQL1), but I couldn't flash directly back - Odin would keep failing on me (can't remember the exact error). What I ended up doing was following the Carrier Switch guide here: https://xdaforums.com/galaxy-s8+/how-to/snap-guide-flashing-standard-fw-carrier-t3627255

Once I was on the Factory Binary (from our baseband version, looks like you're still on bootloader v1, so you'll want to use that factory binary, available at the bottome of the guide), I was able to flash back to XAA. My issue doesn't match up exactly with yours, but might be able to get you back to XAA.

Edit: never mind, didn't realize the date on the quoted post, it's been a few months.

Ok folks this is how I got mine to work. I am using a Tmobile S8+ model SM-G955U with Official Nougat 7.0.

1. Downloaded firmware directly from SamFirm v0.3.6 for model SM-G955U1

2. Used Prince's Odin v3.12 Unofficial

3. Boot my S8+ into download mode (Bixby, Volume Down and Power)

4. Connect phone to PC and verify connection

5. Use corresponding files (BL, AP, CP, and CSC_OYM)

6. Start process

Went smooth with no bloatware! And remember this is not the Oreo build, this is only the TMO build 7.0 Nougat Unlocked without all the additional carrier apps installed.

Good Luck!

Reboot your phone and close odin completely and then reopen it. Connect your phone and make sure it says "added". Then start placing the tars in the proper slots.

Odin is wonky without them. You also need to use Odin 3.12.3 (Prince Comsy) - the one OP has linked. It bypasses the MD5 check.

Also, if you wait too long or somehow screw up the Downloading mode, you will have to reboot your phone into Downloading mode again.

[T-Mobile Samsung Galaxy S8+ Guides, News, & Discus] geoff5093:
Okay, I FINALLY got it to work. I don't know what combination of things finally worked, but this is what I did:

Download Odin 3.12.3 from here: http://xdaforums.com/attachment.php?attachmentid=3804544&d=1467772303

Download the latest Samsung Drivers 1.5.59 from here: http://downloadmirror.co/SLj/SAMSUNG_USB_Driver_for_Mobile_Phones_1.5.59.exe

Install the Samsung drivers, then reboot your computer

Extract the Odin files, right click on the exe and say run as administrator

Put your S8 into download mode by turning it off, then hold PWR + VOL DWN + BIXBY until you see the blue screen, then press volume up.

Plug in your phone. I had to use a USB A to C cable in a USB 2.0 port. Using a C to C cable didn't work. You should see Odin say "added"

Add all four files (BL, AP, CP CSC_OYN)

Profit

EDIT: Okay, so after I did that it looks like it's back on the T-Mobile firmware... Is the firmware file in OP right?
