Background: I am writing this short guide for people like me that want all the info about the T-Mobile 6T unlock capabilities. None of this is my work. I wanted to have a central thread where T-Mobile users can discuss the T-Mobile specifics of this device.
When you purchase a T-Mobile branded OP 6T the device will be SIM and Bootloader locked. Many great people here on XDA found ways around the SIM and bootloader lock. I am simply compiling it all here in one simple thread to be a resource for us T-Mobile users. In this guide you will be directed to the proper resources to SIM and bootloader unlock your T-Mobile 6T and return to T-Mobile software fully unlocked. It doesnt matter if your device is paid off or not. You are bypassing the 40 day wait for a paid off device to SIM unlock!
This is a high level overview for someone that wants quick info and links. All of the info is on XDA but scattered in various threads. I found bits and pieces here and there in those threads so I decided to make a dedicated T-Mobile thread for any T-Mobile user that needs help with the complete process in one simple thread.
So here goes...
Step 1: Convert device to international ROM and unlock the bootloader. Thanks to @AnonymousTipster for this thread! Follow the steps here: T-Mobile 6T to International Conversion (WITHOUT unlocked bootloader/SIM unlock!) NOTE: You MUST use version 9.0.11 to unlock the bootloader (If you flash a newer version make sure you use the patched exe files). After converting to the International version (and going through the set up process) go to Developer options and select OEM Unlocking and turn it on. Now reboot to bootloader and issue the command "fastboot oem unlock" to unlock the bootloader. You are now on the international ROM with your bootloader unlocked.
Step 2: Root and Recovery: Thanks to @mauronofrio for this thread! Now you can root and install recovery on your device following the steps here: [RECOVERY][3.3.0-2][fajita]Official/Unofficial TWRP recovery for OnePlus 6T (Stable).
Step 3: Unlock the SIM . Thanks to @nika_bego for this thread. Follow the steps here: Guide SIM UNLOCK T-MOBILE version all type of IMEI supported.
---NOTE: At this point you can call it quits and keep device as is which is now both bootloader and SIM unlocked on the international firmware (I recommend updating to the latest beta's) or you can continue on with the guide to return to T-Mobile firmware while maintaining SIM unlock (which will lead to boot loader unlock)...
Step 4: Convert back to T-Mobile Device: Thanks to @Dark Nightmare for this thread. Now use the MSM Tool to revert back to the original T-Mobile firmware from here: [TOOL] T-Mobile OnePlus 6T MSMDownloadTool [Firmware 9.0 v1 & v2] This will RE-LOCK your bootloader but not the SIM. You only need to do this if you want to keep the T-Mobile firmware for the updated RCS app, etc. Once the bootloader is re-locked it will take 7 days to get the unlock token shown in the next step. There will be a few security updates once you flash the original firmware back. I would update before unlocking bootloader.
Step 5: Legit Unlock Bootloader Thank OnePlus for this NOTE: Take all OTA's before unlocking. Once unlocked you will no longer receive OTA Updates. You are now on T-Mobile firmware and SIM unlocked. You can proceed to unlock the bootloader the legit way now. Simply follow the steps here: How to unlock bootloader for OnePlus 6T (T-Mobile edition). NOTE: It does take an entire 7 days for the unlock token.
Thats it, your done! You are now fully unlocked and running t-Mobile version of the software (or moved on to other ROMS all together). You can now have root on the latest T-Mobile ROM or stick with a custom ROM.
Feel free to discuss all things T-Mobile in this thread.
Big thanks to the following people for posting all original work: @AnonymousTipster, @mauronofrio, @nika_bego, @Dark Nightmare

I just choose to run stock because I want to keep the device as close to stock as possible. I am pretty happy with this phone the way it is out the box. The only reason I rooted was to install AdAway.

Custom kernels can be great and all. But the stock ones are still very well optimized overall and this phone is constantly giving me 7-8 hours SOT with both custom kernels and stock. Sure, there's the argument of debloating and lightening. But I think stock provides a decent enough experience that doesn't lose out on much important stuff
Nice work but step 2 isn't required. After giving the fastboot OEM unclock command, let it wipe as normal, then before letting it reboor, force it back to bootloader mode by holding vol up, down, and power till it reboots, then just hold power and volume down and it enters bootloader aka fastboot mode. Then give fastboot erase modemst1 and then fastboot erase modemst2. Then reboot. It is also worth mentioning msm 9.0.12 can be used now as long as u run it with the factory patched exe file from the intl conversion thread that was posted with 9.0.11.. Gets you all up to date, a bit faster. Take anonymous tipsters patched exe and copy to msm 12 directory. FYI,.every kernel and ROM for both the intl op6 and op6t work for our phone. Identical. Pixel experience by markash and treskmod actually run better on the phone than stock oos, with about 9-10 hrs sot. .. one plus dropped the ball on ram MGMT, especially with 8gbs of ram and them not utilizing it. Lastly if u stay on TMO firmware, I have a giant list of hacks I'll put together for the strictly stock users. Build prop edits that should be included to begin with.

Step two isnt required unless that is all you plan on doing is rooting. This guide just tries to link to the others guides. Just a high level overview.
Also, great idea. Great idea on creating a list of hacks. Definitely post a link to the thread when you create one.
Just followed this. Windows 8 was being a PITA for adb and fastboot so I upgraded it to Windows 10. BUT.. once I fixed the quirks with my laptop these steps went smoothly with no hiccups. Just gotta wait the 7 days now so I can use the Swift themer and make it look the way I like. Let's see how well this works completely stock for a week. When I first got this phone I immediately switched to international so I've never been able to experience the TMO firmware.
Thanks again for sharing this!

Maybe I'm seeing things.....so even though T-Mobile devices are locked (mainly because you're still paying for the device) you can still get root on the device?

U have been able to do that, u can just bypass having to convince customer care to sim unlock it which gives you access to oem unlock which then allows u to flash twrp/ magisk and thus root...this is possible by unlocking the bootloader.
In overview..
Can sim unlock
Can unlock bootloader
Or just flash patched msm and bypass all of this
Can have dual SIM capability
Can run any software op6, op6t intl.
Can get unlock bin to legitimately and fully unlock device without needing TMobile to unlock anything.

Thats why I made this guide for T-Mo users. Not enough T-Mo users know you can unlock and root with the methods listed in this thread and other threads linked to.
Thanks for this guide. Just dropped my OP6 in my pool and need to get another phone asap. Was going to go to a TMO store tomorrow to get the 6T. If I pay for the phone in full and then follow steps 1-4 (I want root) and to leave it unlocked, will it be the same firmware/state as if I purchased from OnePlus directly?
Update: TMO is saying I need to have the phone for 60 before I can unlock it. Is that correct?
Thanks!!!
Hello Everyone,
I have been using Oneplus phones from a long time and I found it pretty straight forward to just do "fastboot oem unlock" and you are good to go.
Now from what I understand, in case of realme, you have to sideload an realme provided apk and request for In-Depth test which if approved, you'll be allowed unlock your bootloader. I think they (realme) are pushing our serial number and carrier info to their servers to see if you should be allowed to unlock bootloader.
I do not plan to unlock my bootloader right now but I am concerned if realme's servers went down in future or if they stopped providing support for our device in coming year, how would I unlock my device ?
Can I initiate In-Depth test now and actually unlock bootloader later ?
i did it, you never know it might vanish and if you procrastinate, and option vanishes you will kick yourself research for yourself but this thread claims you can re-lock so read it CAREFULLY https://forum.xda-developers.com/realme-x2-pro/how-to/guide-unlocking-bootloader-to-getting-t4010189
fears kill dreams!
who knows what happend to realme or oppo in future or their servers!
X2PRO is 4g device, maximum we may use for next 24-36 months before going to 5g or different device!
i immediately unlock the bootloader, (got approval in 5 mins)
yes you can relock but i don't plan to, (but thats me)
moreover same goes xiaomi, sony also! (the server thing) they monitor what devices are getting unlocked!
Thanks for your replies guys. I understand that I should unlock while I can.
Point is I don't want to do it right now because I am somewhat satisfied with what RUI has to offer. Plus I don't want that safety net headache right now.
I want the option to unlock later lets say when Realme X2 Pro's update support ends and I want to flash Android 12 (when it comes)
My question is, if I get approval and not unlock it, will this approval be retained even after updates and system wipes ? So that I can unlock it later without approval

You can just unlock the bootloader and keep everything stock unrooted. That's what I first did back when I got the phone. There's no harm, other than losing widevine L1, I think.
Got it, thanks.
My original question remains unanswered though.
I'm decompiling realme's in-depth apk to understand what it does when you are approved for bootloader unlock. Will update here if I find anything interesting
if you want to go to android 12 later just follow that thread i showed and relock it and go stock and update

I just got the OP 10 Pro for my girl and I and I'm having some difficulty attempting to unlock the bootloader. Looks like it'll require an unlock token (bin) from OP like the previous models however on my OP 9 I didn't request an unlock token, I think maybe I flashed the global fw with MSM? I know this is a fairly new device and development is limited, but is there anything available at this time to magisk root my device? I still have my old rooted device for 2 weeks grace period before I have to return it for the trade-in.

With the T-Mobile variant you need the unlock.bin to unlock bootloader. OnePlus will eventually update their website, hopefully soon (I've already emailed their support to add it, doubt that will help though). The only other way would be using exploits which haven't been released yet. The good news is once OnePlus updates their site, you can easily request you're unlock.bin and once you get it via email it's super easy to unlock the bootloader.
Sounds like it's like their previous phones subsidized through TMO. Need to pop in a fastboot command on your phone, which will give you a string of code. Copy paste that code on Oneplus' web site once it's updated. From there, you'll need to wait 7 days almost to the minute before the page will display your unlock token, which will be in a .bin format. Fastboot flash that. Of course that'll wipe your phone completely, but your bootloader will be unlocked.

Yes, exactly same as previous T-Mobile OnePlus phones, except there's no need to be sim unlocked to enable oem unlocking on the 10 pro (pretty sure that was by mistake on OnePlus fault).

Wow. Really? So we don't have to make up an extravagant overseas-travel story to get T-mo to unlock? Niiiice.
Have said before, just avoid the US T-Mobile variant, unlocking is just the first of many issues if you're going down the unlocking/rooting path.
If it's your only way of getting the 10 pro then fair enough, but if it's not then choose the other path...whatever it is it has to be better.

Through T-Mobile was my only option but I can't say I had many issues with my OnePlus 9 TMO variant once it was unlocked and rooted.

Fair enough.
I personally live in the UK, so don't have any of these problems, but I've seen issues with people who've flashed a custom ROM and ended up without signal, data, texts, even WiFi, Devs tend not to get involved when asked what the problem may be. They end up frustrated and alone.
Couple that with waiting for 10 days to unlock it, I would stick with "if you have an alternative then go with that".
Whatever way you slice it it's a sub par experience compared to other options.
But hey if you're cool with it then that's your journey
Got my 10 pro unlocked on day one. One plus's site still doesn't support the 10 pro. So no unlock tokens for us yet.

For what it's worth, I just chatted with OnePlus and was told it would take 30-45 days for the unlock token page to be updated with the 10 Pro.
I strongly suspect this was little more than a guess, but I figured I'd relay it just in case.

No, and OnePlus seems to have no interest in updating its unlock token page since the 9 Pro. I have asked several times and no one in cust. service has any idea what's going on months after release of the NE2217.
I only bought the 10 Pro because I expected to be able to unlock the bootloader, as I did easily with the 8. At this point, I'm looking to sell the 10 Pro.
I upgraded from an unlocked 7 pro. I only got the T-Mobile version because they gave me too good of a deal to pass up. Honestly I'm pretty happy with it stock. There's not much you really need root for anymore unless you're developing. It was a big plus back in the day but not so much anymore.
Does anyone live in USA?, need favor.

it'll depend on when T-Mobile gives the ok. T-Mobile is subsidizing your phone so you need to play by their rules.

Honestly if a service provider is going to tamper with the device, just don't bother with them.
I'm in the UK but the crap I've seen people have with T-Mobile and Verizon is just insane, avoid them like the plague.
I think you'd be better off converting a Chinese phone and that's something I'd avoid more than sleeping on the opposite side of the bed to amber heard.
Go global, unless theres a fool proof way to make it to global.
EE in the UK did this on the Sony z1, I ended up bricking my device, so I sent it back via a third party retailer.
Original - EE.
Retailer - carphone warehouse.
They sent me an unlocked version, with a normal bootloader.
Not sure if that's an option for you. A little convaluted but certainly worked for me.

The token unlock page is finally updated to include the T-Mobile variant, NE2217!
Hi all, i don't follow modding world from a while so i don't know what happened more or less into the last 3 years, so now that i need to root the device i wanted to do some questions.
I bought a realme 8 pro at the dayone and now i have the last update installed (so realme UI 4.0). I wanted to do the root but i don't know how much realme support it, if the bootloader is locked or not, ecc. ecc.
I saw in this phone thread that there is a method (the guide is written in May, 14 so it seems very recent) about unlocking bootloader (so i guess is locked?) using deeptest, i tried to read but i didn't really understand what kind of thing is that. So i wanted to ask, what is deeptest? if it is locked, if i successfuly unlock this bootloader what happens to AIO updates? (I guess there will be no updates such as other devices?). If the AIO updates stop to work, Is there a way to manually download and install updates? Can i root this device using magisk for example? I have seen there is something, but there are these things i can't understand.
Thanks in advance for replies and sorry for my bad english.
Hi, yup, the bootloader is locked.
Deeptesting is an app by realme used to request an unlock code. You can try this one https://forum.xda-developers.com/t/unlock-bootloader-help.4425415/post-86777721
Try submitting your application, if it tells you "Your model doesn't support deeptesting" you'll have to follow my guide.
Either way, after a bit of waiting, inside Deeptesting → query approve result → start Deeptesting.
Doing this allows your phone to boot into fastboot. Where you can unlock your phone using
Code:
fastboot flashing unlock
Unlocking the bootloader will wipe your data.
Hi, thanks for the reply! So there is a method to unlock the bootloader. But if i do it, i can't update anymore my device via OTA, right? How could i do that thing. In addiction, is not possible to obtain root permission without bootloader unlock? Because i need root to save whatsapp messages 'cause the application is stupid and can't do a backup by itself.
In addiction... I downloaded deeptesting and my phone does not support it. Yeah
You can get OTAs if, and only if, you didn't modify the firmware. Unlocking itself doesn't break OTAs, but rooting/custom kernels/vbmetas etc. will.
You can't get root without unlocking. As per Whatsapp, I think you can use ADB to back up data without root.
Thanks again. As i know ADB is disabled for whatsapp from a while. Ok then, thanks anyway for all informations. I guess after the bootloader unlock i can install magisk to obtain root acces.
