There was an update to 11.2.3.3 today and my dumb ass took it
Interesting. Well there's no harm in trying to boot off the patched img file. It's temporary. It'll either boot or it won't. A simple reboot will have you booting off the stock boot.
I'm curious what will happen if/when T-Mobile pushes the update to me. There's apparently some steps I can take to maintain the rooting even after an OTA update.

I may investigate trying to get over to the AA version of the ROM, flashing the OnePlus supplied version. This way I can get OTA's from OnePlus directly. From my reading through this forum, I'm not a fan of what T-Mobile has done to the firmware. Especially with that odd self-deleting partition after unlocking that can't be restored.

    I struck out trying to go through Twitter with TMobile. The guy was very nice but he said there's absolutely no way they can unlock it early. You have to pay it off completely and wait 40 days. And you get no discount if you pay it off early. I got put on my very old Sprint account apparently, so I can't use the service here either. I'm thinking I'm just going to return it and cancel the service at this point . So frustrating how these companies prevent you from doing anything.

    So I have a tmo op9pro. The sim is unlocked, I submitted a device unlocking application through op, then I received an email back from op saying the application was approved with a link to download the unlock token. When I click to download the token, a new tab opens up and I see this text:

    I tried opening in Chrome, Edge, and even IE. Same results. Am I doing something wrong? I cant seem to download the unlock.bin file.

    Let me ask if this is the right way. When I click the link for my unlock code Im brought to a page with code. I then right click and save as unlock.bin. I run the fastboot flash cust-unlock command but get the following error.

    C:\ADB\platform-tools>fastboot flash cust-unlock unlock.bin Sending 'cust-unlock' (0 KB) OKAY [ 0.002s] Writing 'cust-unlock' FAILED (remote: 'Error - Verify Failed ! (-1)') fastboot: error: Command failed

    This is really funky. When I go to the OP unlock_token address and click the red button to download, nothing downloads. No option to save as.

    I contacted technical support and they said they would contact me back in 24 hours, so I assume I'll never hear from anyone.

    I just checked the oneplus website to see what you guys are referring to. The unlock.bin should be 288bytes, but what the page is giving is obvious jibberish and 518 bytes. Obviously, oneplus broke their unlock token page. Try contacting support and make them aware that the tokens page is broken.

      Is this a OP9 series issue? I've never had to do this with 7 or 8 series from Tmo to Global... 🤔

      Go read the OP. Things have changed with OnePlus and Tmo devices. Example,no longer able to update zip from system update. No cog wheel anymore. TMobile seems to be trying to lock it down. Fortunately this guyade us a workaround to get EU rom for us. Read the description it's not a bug

      Hello all, this is a quick and simple guide to unlocking your T-Mobile locked bootloader. Just a reminder: unlocking the bootloader will wipe your data. The instructions here will apply to all T-Mobile OnePlus devices.

      1. Unlock your SIM. Some options here
        1. Finding a sympathetic rep to unlock your device. I used the I'm a developer and need the device unlocked for work purposes and took 2 agents before I got mine unlocked.
        2. Finding an awesome XDAer who has the capability to do it, such as https://forum.xda-developers.com/t/...ng-service-oneplus-samsung-google-lg.4231597/ (never used this service, just an example but he seems active and still unlocking)
        3. Paying a (trusted) 3rd party service. I never used them, YMMV
        4. T-Mobile's official policy of waiting 40 days and paying off any balance on an EIP.
      2. Toggle OEM Unlocking in Developer Options.
      3. Jot down your IMEI with *#06#
      4. Reboot the device to bootloader. You can do this via ADB or advanced reboot options in Developer Options.
      5. On a computer with latest fastboot and OnePlus drivers installed, run:
        Code:
        fastboot oem get_unlock_code
      6. Fill out the unlock application on OP's site: https://www.oneplus.com/unlock_token You should have all the necessary information to fill it out now.
      7. Wait for the unlock application to be processed. It can take up to 2 weeks, or even longer on a new device. You can enjoy your still-locked OP9P for now.
      8. Once the unlock application is processed, download the unlock file from the unlock site above, save it (as an example, I saved it as unlock.bin)
      9. With your device in bootloader again, run:
        Code:
        fastboot flash cust-unlock [path/to/unlock.bin]
        In my example, from the CWD as the unlock.bin file, I would run
        Code:
        fastboot flash cust-unlock unlock.bin
      10. Unlock your bootloader with the command:
        Code:
        fastboot oem unlock

      Congrats, your OnePlus device should now be unlocked!

      The unlock token came for me in exactly 7 days and 1 hour.

      The magisk and stock boot.img for 11.2.2.2 is below for T-Mobile variant root

      Temporary unlock doesn't work, must be permanent. If you are really unlucky with support, try #2, he's active and currently unlocking 9 series.


      Read OP, permanent SIM unlock must be acquired before OEM Unlocking is available (or we are waiting for an exploit). Temp unlock does nothing in the context of getting the BL unlocked.

      Oh Geeze. I hadn't looked too closely yet as I just got the phone yesterday. But there goes one of the key reasons for getting the One Plus over the S21 lol. It's on a Sprint account and they couldn't activate it with the T-Mobile sim (according to the rep) so that 1 guy can't help. Geeze. Makes me miss the days of affordable flagships you could buy outright easy.

      I was excited to be back in the scene but it might have to wait until later when I have more of a reason for it.
