Yes ...i did all of that
Ok start with 11 then use oxygen updater to update to 12 global. Once your on Global, you don't need to use Oxygen updater. You can do updates through the phone built in system update. If you still can't get it to work, I have a modified MSM at home that isn't posted anywhere that will update 11 EU to 11 Global. I can send a PM to you later with the link.

Here you go. Open up this MSM after you download it. Make sure you uncheck sha265 check and check use lite firehose. Press start while your in EDL mode. When its done, you will be on 11 Global. You can then do regular system updates without Oxygen updater app. Once your on 12, your sim will not be detected. Use WiFi to update to 13 and you will get everything working again.

Thank u but I managed to do it manually using signed downgrade packages and OnePlus local update app... Now I'm on Global firmware with everything working. Thanks to everyone who provided any help 🤲

Yes... For me... Everything is working just fine
What did you do to keep it?
Every time I try to upgrade to A13, I lose L1 status. I've disabled/uninstalled Magisk, installed it to the inactive slot, but nothing seems to work. I always get L3 after updating.

Yea if you used that MSM then your on a11 Global. You would then need to take system updates to current a13. As previously mentioned, no phone service on a12, you will need to use wifi to update to a13 then you will be good to go. If you don't want to go to a13 then stay on a11.

I have a US TMOBILE LE2127 on the A12. Can I use this tutorial to convert to GLOBAL A13? Do I need some backup (modem or persist) to flash after that? I unlocked the bootloader with oneplus token.bin. I already did a data cleanup. Please help me because there is a lot of information scattered in several posts and I am confused on which one to choose to use in this TMOBILE version with A12.

It will put you on A11 EU then you can take local upgrade with oxygen updater to A11 Global. From there, you can use the built in system update to update to A12 where you will lose phone service. Just update to A13 with wifi and you will be good to go. Learn to READ!!!! I don't like repeating myself. This was mentioned above, I answered already.

The question was to know if I can use for TMOBILE US VERSION LE2127. That's it. Thanks for your help.

Device not match image means your target ID differs from the target ID MSM that your using. If you already converted to EU then use the MSM I posted above to convert EU to Global. If you didn't convert yet, then you need to go back to page 1 and use the tmobile to EU converter listed there by the OP.

    Can someone help a noob out here? lol

    I have a TMO im trying to move to global via EU like here:

    Bootloader is unlocked, got the TMO stuff all done.

    Now I am trying to use MSM and get the firmware etc changed. This is all new to me.


    Downloaded the msm tool and the files from the first post...

    Opening MSM under "other" and I am not getting the phone to be seen. just "n/a".
    usb debugged, drivers etc, running msm from same folder as adb... cmd gets me to see the device and it follows commands.

    Can someone spell out step by step what I need to do next. (like im 5 because apparently I cant follow adult directions).

    TIA for any help
    Make sure you have the Qualcomm QDLoader 9008 Driver installed. And set test signing to on - Google is your friend.
    1
    yes the device manager port shows up as Android Bootloader device.

    driver booster I'm unfamiliar with. I'll have to look that up when I get back.

    I missed your previous post but the PC is updated.

    At this point I'm having trouble even getting the cmd to see it, nevermind msm.
    Android Bootloader device is not correct it needs to show Qualcomm QDLoader 9008 when phone is plugged in and you connect cable. Install the Qualcomm QDLoader 9008 driver. Now with phone powered off open Msmdownload tool hold down volume up volume down button on phone and plug usb cable in phone and phone will show connected in Msmdownload tool. If you follow those instructions to the T in the order I prescribed you will have success !

    I downloaded OB2.. will that not work?

    Also it updated once and now keeps saying successful but keeps saying the next update is the same one.. le2525_11.F17_2170

    So where do I go from here?

    I still need the firmware flash or no?

    Factory reset needed?
    No you can keep updating when you get to f.18 do a factory reset
    1
    odd that it keeps saying the same update is the new update though, no?

    I'll keep going though. thank you for all the help!
    Yes this is normal that is the eventual update that will be coming they don't give you the in-between updates just how they do it when there are so many.

    NP I think you'll enjoy how OOS 13 F.18 runs, it is smooth as butter ! I leave mine stock I got tired of always playing with it it runs great the way it is. Enjoy ! You may be able to find the F.18 file somewhere and install it. Mine runs great on F.18 with no network issues. Here's a link to the fastboot rom F.18 https://androidfilehost.com/?fid=4279422670115718722

    *** Use this at your very own risk.
    *** You will lose all data
    *** Backup your working modemst1/2 and persist. If you lose these for any reason, it's unique to your device and not recoverable if you didn't back up (via MSM or other people).
    *** Read the entire post and follow the steps closely before asking for help. Post all error messages and steps you took. If you just ran a bunch of unknown commands, I would tell you to MSM.
    *** Know how to use the MSMTool, Don't start before figuring it out. https://forum.xda-developers.com/t/op9pro-repository-of-msm-unbrick-tools-tmo-glo-in.4272549/
    *** DO NOT ATTEMPT THIS IF YOU ARE NOT FAMILIAR WITH ANY STEP DESCRIBED IN THIS GUIDE


    General notes:
    • NR and LTE bands are read only and not modifiable, not in modem.img or any other partition. You cannot get global bands by flashing a global ROM, nor can you lose TMO bands by flashing another ROM.
    • If you wish to unlock the bootloader without unlock_code.bin, you MUST do it from OOS11. If you upgrade to OOS12/OOS13, you will need the unlock_code.
    • The T-Mobile NON-HLOS is no longer necessary as of OOS13 release. If you must stay on OOS11 or OOS12, make a backup of the T-Mobile modem partition for the OOS version you want to stay on.
    • Dual-SIM does not work.

    Prerequisites:
    • This conversion will not SIM unlock you. You can only SIM unlock on a T-Mobile ROM, meaning if you want to do that in the future, you must go back to a TMO ROM (and wipe)
    • Familiarity with MSMDownload tools. If the regular MSM tool doesn't work for you, turn back now.
    • Back up all data, it will be wiped.

    Download:

    Steps:
    1. Run the MSM file normally.
    2. Unlock your bootloader if necessary. Now is the time if you don't have unlock.bin
    3. Patch up to Android 13 while on Wifi if your mobile data doesn't work. Use this time to go to another variant (GLO, IN, etc) as needed.

    Fastboot method:
    * The steps in this guide will convert your TMO LE2127 to EU 11.2.3.3. This is intentionally not the latest version to force you to take a FULL OTA.
    * You must already have the bootloader unlocked with an unlock_code.bin
    * You can use this guide to convert to your own variant by extracting payload and flashing from a full OTA. No support will be given if you choose to manually do it.
    * Use the latest platform tools: https://developer.android.com/studio/releases/platform-tools. DO NOT USE MINIMAL ADB, it has not been updated for years.
    * Fastboot can't see your device? https://forum.xda-developers.com/t/...stboot-mode-windows-10.4194491/#post-84943553
    * Test that you can boot to fastbootd prior to starting, "fastboot reboot fastboot" and you should see the OnePlus logo with the text "fastbootd" on top. Do not continue if this doesn't work.
    * When encountering issues, describe all steps you took, paste any outputs, and take screenshots. Make sure to include the output of fastboot --version in your post.

    Steps to convert your device to EU
    1. You need your device bootloader and SIM unlocked. See https://forum.xda-developers.com/t/how-to-unlock-the-t-mobile-bootloader.4256319/
    2. Download and unzip the conversion package:
      • EU 11.2.3.3
        MD5: cb949816fa80d5f0d984359b819426c3
    3. Boot to bootloader.
      • From adb:
        Code:
        adb reboot bootloader
      • From fastboot/bootloader:
        Code:
        fastboot reboot bootloader
    4. Execute "flash_all.bat" from the unzipped directory from step 2.
    5. Reboot into recovery, and wipe everything.
    6. Once fully booted, connect to WiFi and download Oxygen Updater and take the FULL OTA (11.2.4.4 as of this writing)
    7. Do a regular reboot, don't reboot to fastbootd, bootloader, recovery, etc. Reboot to system.
    8. Reboot into bootloader or fastbootd, and flash the T-Mobile modem.
      Code:
      fastboot flash modem NON-HLOS.bin
    9. After each Full OTA you take in the future, you will need to repeat step 7 & 8

    FAQ
    • Q: The most recent version is 11.2.4.4, why is this guide converting to 11.2.3.3?
      A: You didn't read the full post.
    • Q: Why is there no conversion to Global?
      A: Global variant uses the Google incremental OTA server, and full OTAs are not always provided. There's no functional difference, and EU has better privacy requirements anyways. You can do it manually by extracting payload.bin and running the same flash script. No support will be provided if you choose to flash to Global.
    • Q: Can I re-lock the bootloader after conversion?
      A: While you can go ahead lock your bootloader after conversion, I don't recommend it as you will not be able to take incremental OTA due to modem changes, and lose connectivity if you take a full OTA. To fix it, you need to unlock the bootloader and end up wiping.
    • Q: Where is the Linux guide?
      A: Too lazy, if you're using Linux, you can make your own bash script from the Windows batch script.
    • Q: Help, I see is 'fastboot' is not recognized as an internal or external command.
      A: Your fastboot.exe is not in your $PATH. You can either drop fastboot into the same folder as flash-all.bat, or you can fix your $PATH
    • Q: Help, I cannot boot to fastbootd because previous flashes messed things up.
      A: MSM
    • Q: Help, "not enough space to resize [system, product, system_ext]"
      A: MSM. If the error is on Vendor, it might still work and boot with a generic Android boot logo. If so, take the full OTA as described in the guide.
    • Q: Help, something went wrong!
      A: Post in here the starting state of your device (Device model, ROM version, etc), all steps you've taken since unlocking bootloader, and the output of whatever is causing you trouble. Chances are, the answer is MSM, but read my MSM warning.
    • Q: Help, I see "Invalid sparse file format at header magic"
      A: Ignore this message, not an error


    Fixing the About Phone page

    These steps are optional, and is only applicable for OOS11. It will fix the "About Phone" page. There are no performance differences. All that's done is change build.prop to reflect the correct model.
    1. You need to rooted with Magisk
    2. Download and install the magisk module: here
    3. Reboot, the About Phone page is filled out.


    Instructions to Bootloader Unlock a SIM locked device:

    1. In ADB:
      Code:
      adb shell pm uninstall -k --user 0 com.qualcomm.qti.uim
    2. Reboot
    3. Go to dev settings and enable OEM Unlock
    4. Reboot to bootloader
    5. Code:
      fastboot oem unlock
      No unlock.bin needed


    Issues so far (please post if you run into more):
    • If your mobile data doesn't work on OOS13, PM me details including HW Revision in About Phone.
    What appears to work:
    • Everything else.

    Much appreciation for everyone that help develop and test

    Due to OnePlus's incompetence on running a website, the MSM conversion is released today to enable bootloader unlocking for folks who are SIM unlocked but can't download an unlock.bin

    Link to the tg group I'm willing to help or find a fix for this also my Bluetooth will randomly disconnect then reconnect my Garmin watch. I did notice it disconnected my airpod before once but haven't had that happen yet just happens more often with my Garmin watch.
    If you don't have root or unlocked bootloader backup using MSM tool. When in the screen where you would normally flash the rom, press F8 key. You will see list of partition, password is oneplus to use backup.

    Yes you need to do incrementals. F17 is the latest version and you can't go straight to that. Just use the EU to GLO MSM I posted above if you don't know how to use oxygen updater local uograde, that will put you on a11 GLO then you won't need oxygen updater, you can just do regular system updates to f.17 GLO.
    Thanks! That's what i did. By the way i used the system LE2123 to do updates until A12 and stopped. Dowloaded the One+ local update app for A12 and used the Zip Full LE2125 F17 from OxygenUpdater app. Now i am on A13 GLOBAL and doing OTA updates normally. Thanks for all your quick support, it was very important to me conquer the aim.

    Thank you for all the help it helped me convert my first oneplus device Im glad I did it.
