How To Guide How To: Unlock the T-Mobile Bootloader

[plzdonthackme]

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>

What is the reason to convert it from TMO to EU?

Getting bootloader UNLOCK CODE without unlocking a sim card




SIM card unlock required for Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > OEM Unlocking
because without unlocking the sim card it is inactive
To bypass this limitation, follow the guide below.

Spoiler: STEP 1: Install Android SDK

First and foremost, you will have to install the Android SDK Platform Tools on your
PC. This is the official ADB and Fastboot binary provided by Google and is the only
recommended one. So download it and then extract it to any convenient location on
your PC. Doing so will give you the platform-tools folder, which will be used
throughout this guide.

Spoiler: STEP 2: Enable USB Debugging

Next up, you will have to enable USB Debugging on your device so that it is
recognizable by the PC in ADB mode. So head over to Settings > About Phone > Tap
on Build Number 7 times > Go back to Settings > System > Advanced > Developer
Options > Enable USB Debugging.

Spoiler: STEP 3: Establish ADB Shell Connection

1. To begin with, connect your device to the PC via USB cable. Make sure USB
Debugging is enabled.
2. Then head over to the platform-tools folder, type in CMD in the address bar,
and hit Enter. This will launch the Command Prompt.
3. Now in the following command in the CMD window to verify the ADB
connection:

adb devices

4. If you get the device ID, then the connection stands successful. Now type in
the below command to open the Shell environment:

adb shell

5. It will now list out your device name/codename, which means that the shell
connection has been successfully established

Spoiler: STEP 4: Enable OEM Unlock in OnePlus via ADB

1. Now just execute the below command to disable the Qualcomm system app
which in turn will enable the greyed-out OEM Unlock on your T-Mobile
carrier-locked OnePlus device;

pm disable-user com.qualcomm.qti.uim

2. Once that is done, head over to Settings > System > Advanced > Developer
Options > and you will now be able to enable OEM Unlock toggle.
3. However, if the toggle is still greyed out, then you will have to uninstall that
app from your device. For that, use the below command

pm uninstall --user 0 com.qualcomm.qti.uim

Spoiler: STEP 5: Get SN,IMEI, UNLOCK CODE

1. Go to fastboot and use the below command

fastboot oem get-psid

result:

(bootloader) SN:XXXXXXXXXXXXXXXX
(bootloader) IMEI:XXXXXXXXXXXXXXX

2. For unlock code use below command

fastboot oem get_unlock_code

WHEN COMPLETE go to 6-th step of main guide

Im having issues with my new 9 pro, I am getting

FAILED (remote: 'Please flash unlock token first.')


when I try to fastboot oem unlock

It is a LE2125 so how am I getting this? I enabled developer settings, enabled OEM unlocking, and turned usb debugging on. It sees the device when I fastboot devices.

Do I need to do this to get it unlocked? How is it locked???





Edit: nuked picture cause nachi mods have to keep this place safe for the children

Try:

fastboot flashing unlock

I have additional suggestions if that fails but I think that will work for you


Edit just in case that doesn't help:
Did you buy it new, used or from a chinese reseller on Alibaba or similar? What does About Phone say? What does the sticker on the back of your phone say?

Any chance it was a TMO model that someone flashed Global rom onto? Have you tried any Global or Tmo msm tools or done any flashing previously?

Thanks for the reply.

It was from Swappa, from a really big seller in Cali. I am going to try this now, and let you know.

It did say that it was an Unlocked, but from Cricket Mobile. In the settings it had the LE2125 model number. I just turned it on and tried to unlock it, I havent used any tmo or msm tools, or any flashing.

EDIT:

So I tried it and it gave the same error:

$ fastboot flashing unlock
FAILED (remote: 'Please flash unlock token first.')
fastboot: error: Command failed

Thanks for the reply.
.....
fastboot: error: Command failed

Wow ok, so I never read the sticker on the back, it is a LE2127, so they must have flashed it. I am gonna get the unlock token from tmobile.

I got the unlock.bin and get this error when I try to flash it:

fastboot: error: ANDROID_PRODUCT_OUT not set

I cant find much on this error.

If you use the Eu conversion tool https://forum.xda-developers.com/t/...7-to-eu-via-msm-no-unlock-bin-needed.4272837/, you can bypass the need for Tmo token altogether. Use the Tmo->Eu conversion tool and unlock the bootloader while on oos11. If you update to oos13 before unlocking, you'll need the token again.

OnePlus tokens have been having issues for months it seems. I've seen people saying they have to email them because the generated ones aren't working right. I didn't have that experience but I did mine late last year.

Use the conversion to convert from Tmo to EU, unlock bootloader, flash global (https://forum.xda-developers.com/t/...onverted-to-global-le2125-oos-13-ob2.4512829/) and then update to latest global... If that's what you want to do. I am on Eu OOS11 and everything is fine. I did flash my original modem back in.

Latest EU oos13 is giving issues so people are going to global to fix their connection issues. From 11 to 13, all of the Eu versions work fine except the latest one, as far as I know.

Before you do anything, take back ups of modemst1/2, efs/persist with msm tool readback (press F8, password is oneplus). If anything goes wrong, you'll have everything needed to fix it

I had to fight tooth and nail with OnePlus to get my unlock token. There website was hacked for a while. Now because of copyright issues OnePlus is pulling out of the European markets. I was lucky to get mine before things start going South for them. Anyways it took me talking on the phone with them at least 5 times, a few chats, my service request elevated 3 times and me submitting the unlock info to them to FINALLY get my unlock bin token. This took a little under two weeks.
