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!

Just keep trying, sometimes you get really unlucky. I have made $0 payment so far and had it unlocked on the first day I took it home. The store won't be able to help though. I used phone(8T) / facebook(9pro), twitter should be the same team as facebook and these are your best bets.

Just bought my OP9 Pro this am from T-mobile. Bought it on a promo so they were hesitant to unlock the device but I told them I was an Android Dev and travel world wide and not only did he not make me pay it off to unlock it he refused to take my money and whitelisted my phone before even activating it. So to their point above or below, keep trying and you will get someone nice. Or change your story. Up to you

I was able to get it unlocked via T-Mobiles twitter support on one try, Maybe because I payed off half the device already . Keep trying

They gave me a temporary unlock but I still can't toggle the oem unlocking button its greyed out. Am I doing something wrong.

Both of you have made statements that sound like you are talking about SIM unlocking. This is bootloader unlocking and is not related. T-Mobile support isn't there for you to unlock your bootloader and yes they will grant a temporary sim unlock if you need it.

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.

You can just put a tmobile sim in a Sprint branded phone, it'll be fine. Go to a tmobile store and ask for tnx sim if you have everything paid off. Otherwise call sprint and get a tnx sim.

So I know this isn't the proper place but wanted to ask some opinions or maybe somebody can point me in the right place if needed got T-Mobile's OnePlus 9 didn't want purple box said silver opened it up yep it's purple!! Rep didn't know what to do so I took it home I'm going back thinking of switching to the pro but $75 I think restocking fee is it worth switching to the 9 pro. Any info and possibly reason to switch outside of purple would be appreciated thank you

    Depends on what you use your phone for. You can look up the differences. Personally, the regular OnePlus 9 should be ok and you'd be better off waiting for the upcoming series before upgrading, but that's just a recommendation.

    Hey guys, just wanting to make sure I understand the process. I haven't been rooting or unlocking a bootloader since android introduced their different pay apps and all major carriers started locking their bootloaders. So the OP post says you need to attain an unlocked sim to be able to get the unlock iem option. So then it would be needed for t-mobile devices that were purchased from one plus, right?

    If you purchased your phone from OnePlus it would already be sim unlocked

    This thread only deals with T-mobile branded models (op9p would be model LE2127, for example). If you bought from the oneplus website, the instructions here won't apply

      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

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