Now that Oxygen OS 13.1 is officially coming to 9 Pro I'm wondering if it will be possible to get our Le2127 flashed to 13.1 as well.

Follow all the instructions to get to F.17.
Once you are on F.17, your device should be an LE2125.
Once on F.17 you *should* be able to flash to 13.1 using Magisk Modules / Install From Storage.
After flashing 13.1 DO NOT REBOOT YET.
Flash Magisk Install / Install to Inactive Slot (after OTA) THEN REBOOT, to keep Magisk Root.
After the reboot use Magisk Modules / Install From Storage, to install TWRP to recovery (if you want to have TWRP as your Recovery) then you should be golden....
IIRC, this procedure *should* work.

I'm already on F.27, so you must mean that I need to use msm tool for my device to get to the global version? Once on the global oos11 I keep updating until I'm on F.17 which the device should identify as a le2125 at that time?

After that I will need to do more research because I really didn't understand the rest. I wasn't aware that magisk had the ability to flash roms. So yeah I'm very confused by that remark. But F17 global sounds like a good start.

The current T-Mobile OOS13 F27 is running great on it, but I was hoping the latest OOS13.1 would run even better on it. But I have not seen anyone do it yet, at least not this tmo phone. Lol

I downloaded the TMO to Global but everyone keeps saying to go to EU and I'm not sure why if my phone is a USA TMO phone. Shouldn't I be flashing to global oos11 (using the official tool) and then updating all the way to oos13? There just doesn't seem to be clear instructions anywhere. One set of instructions says this, while another says that, EU, Global, TWRP, Magisk, etc.

How do I convert to LE2125 or at least stay on LE2127 with the ability to root? Is there a definitive option that is better than the rest? I will follow the directions so long they are clear. I have never used msm, and I haven't used Magisk or TWRP since their very early days like almost 10 years ago.

I'm bootloader unlocked, rooted with magisk 26.1 on stock TMO OS13 with no issues. What do you really want to do? I have the TMO 2 GLO conversion MSM Tool if needed!

I downloaded the 3.5gb file that you posted a few days ago. I'm just not sure what to do with it. My goal is to unlock bootloader, be on the latest version of OOS13 that is known to run good on this device, maybe flash a 3rd party kernel for that extra little bit of performance, install a back up app such as swift, and enjoy a great running Android phone which I believe this phone is capable of being.

I have already installed ADB and the OnePlus usb drivers and I believe I have a decent usb cable. I don't care if I'm using the TMO rom, but I assume it's best to be on global so that the device gets updates via OnePlus?? Just not sure. Anyway, I have never used msm tool and I'm not even sure that is how to unlock the bootloader. Do I need to wait for token bins to arrive, do I use the official TMO to oneplus instructions listed at the OnePlus website? Lol, I'm guessing there's a better way?

I'm currently on F.27. What should I do next? Thank you

Edit: I'm guessing I should convert it to LE2125?

You can convert to GLO and unlock bootloader and then if you wish, convert back to TMO with unlocked bootloader and update to OS13 if you so desire

How do I convert to Glo? And after converting, how do I unlock bootloader? Is there a program for unlocking bootloader, or do I need to simply follow the OnePlus instructions using the token method?

I will provide the resources here tomorrow.
In the meantime, disable driver signing on PC, reboot PC, download the latest OnePlus and Qualcomm USB drivers and install them and then reboot PC. Then you will be ready to convert the phone!

    First convert to EU using the TMO to EU MSM Tool then install global firmware from the OnePlus website. Update it all the way to C.65 then install the OOS 13 F.17 firmware, go into settings and factory reset and your done VOILA ! Everything works including 5G mm wave with no root or data retention.

    Ey folks, I'm trying to follow the process with some misunderstanding:
    1- I converted to EU using https://forum.xda-developers.com/t/...7-to-eu-via-msm-no-unlock-bin-needed.4272837/ until step 2 (inclusive)
    2- I downloaded OP ROM OSS 11.2.10.10.LE15AA and installed manually

    Phone still indicates model LE2127 and suggest me to update to LE2115.11.F17_2170_202211231111

    Should I proceed with it instead of F16?
    What about "Update it all the way to C.65" where can I download them?

    You can find several versions of upgrade boot and apk files here:

    Different variants of Magisk that are...

    Edit: The first post has an apk and instructions along with boot images. The second post has firmware zips for various versions

    I did all of this and am now on F.16 but unable to unlock bootloader. Were you able to unlock bootloader? I was able to before going to A13

    You have to unlock the bootloader while on A11. After running my conversion MSM, first thing you should do is unlock the bootloader before updating to A12/A13. If you don't, you will not be able to unlock it later without the unlock_code.bin

    The only way the model will change is if you follow the conversion directions and use the MSM Tool in the links provided in the conversion directions.
    Otherwise it will stay as an LE2127.
    The conversion process gets rid of the TMO ROM and overwrites the device with OnePlus OOS ROM and Firmware via the MSM Tool.

    Hello everyone,

    I am new here - I bought the LE 2127 by mistake as I was going to try and de-Google the OnePlus 9 Pro by flashing Lineage OS. So I have a few questions that I hope someone will answer as I am not a developer but learning every day. I have already downloaded and used adb & fastboot on to my Pop OS laptop and taken out quite a few google apps including the Play store and replaced it with MicroG and my banking app works just fine. I get the occasional error with Signal, but it still works. My concern with the OnePlus is a Chinese backdoor? Anyone know about that and if there is one on this model?

    Here are my questions:

    1. Are you guys in the US? I am in the southeast.
    2. Changing the LE2127 to LE2125, will that work with Mint?
    3. Once I follow the directions and change to the LE2125 - I should be able to switch to another Custom OS? Like Lineage, right? The LE2125 is the last model they support.
    4. Would I be de-Googled with OOS or do I have to re-de-google the phone again...

    Mostly, what are the benefits of switching to LE2125 if you keep Oxygen; just getting rid of the T-Mobile apps? As I said, I am a total beginner, so any advice would be amazing.

    #2) yes, it should continue to work fine, you'll flash your current modem back in anyway (if android 11 or 12, some say 13 works) Be sure to backup modemst1/2 to be safe. Multiple users report success with Tmo mvno working just fine all across.
    #3) yes, you should be able to.
    #4) you will have to re-de-google because you'll be going from Tmo to EU using the MSM tool, it's a clean slate and like-new state.

    The first benefit is flashing Tmo->EU allows you to unlock the bootloader without the OnePlus Token site. You can unlock it the traditional way. Neither way requires the sim to be unlocked but it's certainly more convenient than waiting a week.

    I would recommend submitting to OnePlus Token site just to have the backup option/unlock token bin that matches your device. I submitted mine and immediately flashed to EU and unlocked. Then when I flashed back to Tmo, I verified the unlock worked either way.

    And the cruise over to global/other roms.

    The other benefit is not having any of tmobile's bloatware, animations, and preventing automatic updates. I don't know 100% for the 9P but the Tmo 7TP5GME, they force the update, you can't prevent it by postponement. Having root and unlocked bootloader also didn't prevent the update from happening. I've since read that the Tmo variants can push the update and restart (so you lose root because you can't go flash magisk boot OTA back to inactive slot). Others who weren't yet to the maximum postponement amount would block the download servers in Hosts with root and avoid it that way
