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

[craznazn]

When trying to unlock my bootloader I keep getting this error message: error: cannot load 'unlock.bin
Can somebody PLEASE help me out

Is unlock.bin in the directory you are running fastboot from?

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.

I appreciate you going the extra step and confirming it's not us. I've reached out to tech support numerous times. The response I get from tech support is "our phones aren't locked, you need to contact TMO." I don't think op trained tech support reps know about the unlock token. I literally sent multiple reps the hyperlink to the unlock token page and they still told me to contact TMO.

unlock code worked for my op9pro on 04/22/21.. but for the second one it gives bullsh+t code. Also if u download an older token it still comes up as broken. This is going to be a long road....

Ive also emailed support.

Can confirm this also, got my unlock token email today, and went to download nothing but a bunch of jibberish symbol's....tech support is saying it's a TMobile problem...I tried explaining several times to 3 different people it's the one plus sites problem, and they basically kept telling me contact TMobile. Looks like this could be the end for us TMobile users, as OnePlus seems to think it's not their problem.

Yea I've given up on Oneplus Support doing anything about it. Several email exchanges with them and they just dont get it.
