AT&T USERDATA for bootloader 8 has been added - build TK4.

I also added the full firmware package because, while lots of other carriers got this build, I didn't see that anyone else had uploaded it on AFH yet.

And, from now on, you can expect AT&T USERDATAs to be added right away, when new bootloaders and new Android versions are released :)

after alot of time unsuccessful attempt flashing and getting "threads completed. (succeed 0 / failed 1)" message from odin i finally manage to flash the firmware from G965U(T-Mobile) to G965U1 by doing this step.

1 -remove the sim card from the phone.
2 -Hard reset the phone.
3 -let the phone boot up to first intro and power it down and go to the download mode.
4 -flash the G965u1 (SM-G965U1_XAA_G965U1UEU7ETH2) firmware using modded odin

if that failed, format and install fresh windows on your pc and install all the required drivers and software for flashing the phone and try the step above again.

Good luck.

Bootloader 9 files have (finally) been added for AT&T - both USERDATA and (because I think every other carrier got v9 back in January, so no one else will get this same build) the rest of the full firmware files

hi all, thx to everyone who has contributed to this lexicon of firmwares and knowledge... but...

...just to ensure im not off the mark here, i have a S9+ that i bought for my nepbuild hew locally (in the USA) that was advertised as "Unlocked"... I gave it to my nephew who put his Cricket SIM into it and all works EXCEPT for calls, they fail immediately, but SMS/MMS/data all work... the phone is indeed SIM unlocked, but in the software section it shows "service provider sw ver. = TMB/XAA/VZW", the phone displays a Tmobile boot screen (with insanely irritating chime!) at every boot and has Tmobile bloat included... from what i gather this started out as a Verizon-branded phone, was unlocked, then flashed with a Tmobile firmware version (build number QP1A.190711.020.G965USQS9FUA2)... my nephew being a Cricket user Im assuming flashing this phone to the ATT carrier version should allow his SIM to work for calls, is this correct?

i have downloaded the ATT_Userdata file in the first post of this thread, along with the 3GB G965U_UB5_9.zip that was in the same folder, do i also still need a G965U1 firmware package to flash before i use the ATT files, to remove the Tmo bloat? should this work to get his phone working for calls? i have downloaded and installed the patched Odin build along with the Samsung USB drivers already.

thanks in advance for any clarification, really hesitant to proceed without some confirmation.

You may be able to force the bloatware to switch just by inserting an AT&T SIM. Try that, before messing around with firmware

Does anybody have an unlocked BL that is for the G965U1UES9FVD1? I have spent days trying to unlock the OEM enable option.. but it is hidden and unable to flash TWRP or anything.

The latest IMG that i was able to find off other ROMs that were unlocked is for v7. Unable to flash v9 w/ ODIN.

Anybody know what else I can try at this time? I have ran out of options.

BL unlocking doesn't work that way. It's not done with firmware files.

It can be done on your model, but requires a paid service

    For those who aren't already aware, G965U is the model number of all of the US carrier versions of the S9+. The G965U1 is the model number of the same device, but sold by Samsung SIM unlocked and with no carrier bloatware. Firmware is 100% interchangeable among these models: any U or U1 firmware version can be flashed to any U or U1 device at any time, assuming that you're not trying to downgrade the bootloader. A "U to U" or "U1 to U1" flash does not require a factory reset, but changing from one firmware to the other will require one. Also, U firmware is identical for the 4 base files (AP, BL, CP, CSC) for each individual build, no matter which carrier it comes from. So if you download 2 different carrier versions of the exact same build, the 4 base files will be identical. Where the firmware differs is in the USERDATA file - that's where the carrier bloatware and customizations reside.

    Manual Odin flashing is designed for those who:

    - want to manually update to a newer version of U firmware on their U device, either because they don't want to wait for their carrier's OTA or because OTAs aren't working on their device, or a different carrier got a new feature/patch before they did
    - want to flash U1 firmware to their U device
    - want to convert from U1 firmware to carrier U firmware
    - want to convert from one carrier's U firmware (with all apps and bloatware) to a different carrier's U firmware (with all apps and bloatware)

    For those who aren't already aware, anyone can now download firmware for almost any Samsung device any time that they want, via SamFirm or Frija. There are threads and info about them here on XDA so I won't waste time explaining - do a search if you're not already familiar with these tools. But they only provide whatever the latest/newest/current version is - nothing older. I pay for a subscription to a site that gets the official releases (usually) before they hit SamFirm/Frija, so that's where my files come from. However, I don't have unlimited bandwidth on the site, and it's also quite time consuming to download the files, zip them up, and upload them to AFH. And, I do threads like this for every single Sx and Note x model - so I won't be uploading every single version. The only full builds that I upload are ones where I get access to a new bootloader and/or Android version early, before they hit SamFirm/Frija.

    This is not a "beginner's guide to Odin flashing" -type post/thread, so I won't list basic, step-by-step flashing instructions. My threads are geared towards those who already know what they're doing. If you're new to manually flashing Samsung firmware (or haven't done it in a long time), I recommend you consult one of those "beginner's" guides- there are tons of them here on XDA.

    Odin 3.13.1 3B Patched is required for flashing these.

    Happy flashing!

    U firmware: https://www.androidfilehost.com/?w=files&flid=257072
    U1 firmware: https://www.androidfilehost.com/?w=files&flid=257075

    Notes:

    - DON'T QUOTE THE OP WHEN YOU REPLY, kthx

    - I have lots of threads just like this one for other Samsung flagships, if it interests you. For those who have already made use of my previous threads for a different device and are upgrading to an S9+, welcome back :)

    - My zips are compressed extra small for space and bandwidth savings. The default Windows extractor can't handle it, so you'll need a 3rd party tool like 7zip, WinRAR, etc

    - My naming method for folders on AFH is: build - bootloader - Android version
    So "SAT - 1 - 9.0" means the full build number ends in SAT, it's bootloader version 1, and it's Android 9.0. When bootloader and Android versions increment, the first build to have those changes will have its folder notated appropriately.

    - HOME CSC file keeps data intact; using the other CSC will wipe data. Flashing USERDATA will also wipe data.

    - Since AT&T doesn't allow their firmware to be publicly available (for any of their devices), I'll try to always upload at least one USERDATA per bootloader increment for AT&T. I'll also upload any full builds if AT&T is the only carrier to get that specific build, because you won't be able to find the files anywhere else.

    - For identifying USERDATAS, and to know what region/CSC to use in SamFirm/Frija:

    ATT = AT&T (not available via SamFirm/Frija)
    BST = Boost Mobile
    CCT = Xfinity Mobile (Comcast)
    CHA = Spectrum Mobile (Charter)
    SPR = Sprint
    TMB = T-Mobile
    TMK = Metro PCS
    USC = US Cellular
    VZW = Verizon (available via SamFirm/Frija, but Manual Entry is required - Auto will not work)
    XAA = U1 firmware

    - the correct procedure for switching from one carrier's firmware to another is:
    1. Flash full U1 firmware package including non HOME CSC
    2. Upon boot, insert a SIM of the carrier whose firmware you want
    3. Watch for the popup that says "reboot to apply new carrier settings" etc, and do it
    4. After that restart completes, reboot back to Download mode and flash the full U firmware package, with the USERDATA file of the carrier whose firmware you want

    Oh nice! So the next Ota would always be the unlocked firmware? Is there a thread for detailed instructions? Like I meantioned, my last Samsung was an S4.....

    ---------- Post added at 07:11 AM ---------- Previous post was at 07:00 AM ----------



    Is there a detailed writeup on how to do this? Last Samsung device was an S4.

    Here is a quick guide

    Proceed with Caution. This is a firmware flash using Odin and will not trip KNOX.

    * Download Mobile Driver for Samsung phones and install it

    * Download G965 U1(Unlocked Model files) from here

    * Extract using 7-Zip(WinRar will error out)

    * Download the PatcheD Odin from here

    * Factory Reset the phone and remove your Google Account if you have already set the phone up.

    * Assemble all required files on Odin

    * Put the phone into Download mode by holding down the Bixby Button, then the Volume Down button and then the Power Button. Hold all 3 buttons down till a warning page appears, proceed by pressing the Volume up button

    * Connect the Phone to your PC using the factory cable

    * Press Start on Odin

    * The whole process should take about 5 minutes to finish.

    * The phone will restart twice and voila you will have an unlocked S9+ with no carrier boot logo or bloat.

    I will stop posting any leaks for Pie, that way i don't get accused for it for the S9 or S9 Plus, this is something that's always been warned on people to install on there own RISK, and not me being responsible for there actions if something goes wrong with there phones.

    This is a huge shame. Not that I'm interested in the Pie builds right now since they are so buggy, but the fact that you even have to not post because people are complaining of their phones not working is just a shame. For me, Xda is a place for getting leaks, custom roms, and apps that are outside the box to the point where they sometimes can't be on the play store. While most things on Xda are tested before being posted, it's always been a bleeding edge, use at your own risk type of site.

    I've been coming here for years to extend the life of phones, rooting, and running custom roms. This kind of nonsense (people complaining about a clearly marked unstable alpha not working right) reminds me of the whole issue in society today. People just don't want to take responsibility for anything. The entire reason I haven't tried the Pie builds is because it's buggy. That's why it's an alpha. I can't afford to be without my phone, so I stay put on Oreo.

    Anyways, I'll stop my rant. Glad to have you here and appreciate the leaks and all you bring to us. You've been awesome throughout the years (my Evo3d rocked your rom the whole time I had it), and if you haven't heard it from anyone recently, I totally appreciate your work!
