Based on a handful of google searches, I suspect the app is already installed but hidden. Not sure how to access it, though. I'm able to get into "engineering mode" by dialing *#808# but I don't see anything in there about accessing other apps or unlocking the bootloader

Hey everyone. After over a month of back-and-forths with OnePlus support, they sent me a new unlock token via email and it worked for unlocking my device. I suspect their unlock token site was buggy.

OnePlus 8T
After a week I received the "unlock_code.bin" file via the website <https://www.oneplus.com/us/unlock_token> but unfortunately it was impossible to flash the file due to a "verification error" so I requested a new file from Oneplus support via email <[email protected]>. I recommend adding to the body of the message exact model of your device (Oneplus 8T KB2007 in my case), serial number, IMEI, PCB number, unlock code and screenshots of the information shown in Settings/About device. After a little over a week I received a new file "unlock_code.bin" via email (A shout out to Leo Smith).

I then proceeded to convert my TMO device to EU using MsmDownloadTool. In my case I used the files from the following website <https://firmwarefile.com/oneplus-8t-5g-kb2007>.

It was necessary to install the Qualcomm driver from Windows test mode for MsmDownloadTool to recognise my device in EDL mode. I found a guide about it on the Oneplus forum (Step 1 to 3) <https://community.oneplus.com/thread/306306>

    I have done some searching on the forum about rooting the T-Mobile version of the OnePlus 8t and seeing road blocks when it comes to unlocking the device, that was this spring.... Has there since been methods found since then to unlock and root the kb2007? TIA!
    If you want to stay on T-Mobile rom you need to first get it sim unlocked with code/help from T-Mobile and then request a unlock token from oneplus to unlock bootloader.

    Or you can use this modifed MSM tool to convert to the EU rom. But to be able to unlock bootloader you need to be sim unlocked (and you can only do that while on the T-mobile rom)
    I received unlock from one plus, inserted and unlocked the bootloader.
    I'm on
    Spent 4 hours getting twrp on & now can't load the custom boot img created in it from from oxygen updater (local option is not there.)
    Is the the kb2007 just not root-able now?
    Have been reading about flashing international firmware through fastboot but am confused of that process.
    I am using an KB2007.

    https://www.oneplus.com/unlock_token - To get your unlock token.

    fastboot flash cust-unlock unlock_code.bin
    fastboot oem unlock
    select yes (reboot the device and wait for the wipe to complete)

    Do you plan on keeping the stock firmware or an custom rom?

    Assuming stock -
    fastboot boot twrp-3.5.2_11-0-kebab-20210904-alpha.img
    Select Advanced -> ADB Sideload
    adb sideload Magisk-v23.0.zip (This depends on your version of Magisk or root pkg)
    reboot system.
    Any incite on this too anyone please?

    That is an article on using the MSM Tool to rebrand your device. You will need to install the Qualcomm Drivers first though.
