Oneplus 7 Pro T-Mobile Network Lock

[Johnrochasep]

Hi everybody,
It's great to finally "participate" after having found so many helpful posts.
As so many other people, I was fooled into buying a Oneplus 7 Pro, which I was told, was SIM unlocked.
Once I got the phone and inserted my SIM, a message popped up saying it is network locked to T-Mobile.
Here's what I've tried:
- T-Mobile Device Unlock app did not work.
(Some kind of error message)
- Flashed international
- Flashed T-Mobile again
- Flashed DP3
- Unlocked bootloader

Nothing works!

One of those websites that charges to unlock phones what's to charge me 90 euros for this, but I know how trustworthy that is. It's a lot of money.

With so many ways to unlock phones now a days, I'm surprised no one has been able to crack this thing.

Could it be just a question of time?
I'm sure someone will soon find a way, or if there already is a way, but I haven't found it, could someone please share a tutorial or a link, something please?

Sorry about this being my first post, but this is, hopefully just the beginning.

Thanks to all.

Yesterday I tried something else, from a video on YouTube for the modem/SIM unlock for the 6T.

Going through the command prompt in Windows and using the "fastboot erase modemst1" it did not work on the 7 Pro.

Any ideas as to how to get this command working on the 7 Pro?

Thanks

I have the same problem. I payed someone on ebay to unlock it but they refunded me as they were not able to unlock it.
Would be nice to find a solution .

They can't do it, got refunded. Neither does removing modemst1 and st2 partitions

Thanks for adding to that
At least now I know not to try those sites.
Sooner or later, there must be some way to crack these things.
Wouldn't it be possible to just make it think it's a GM1910 or a GM1913?
Completely replace the entire software from scratch.
It might be possible because the hardware is all the same...........? Right?

I am in the same situation. They couldn't unlock my phone and made a refund (ebay).
I unlocked the bootloader and flashed the international version.
I made a backup of my efs by TWRP.
Then I erase the efs areas (modemst1, modemst2, fsg, fsc) by using the QFIL program, but it did not work.
I found a comment on 4pda forum that efs data is recovered from the "/dev/block/by-name/oem_dycnvbk" section.
I made a backup of this section by using "dd if=/dev/block/by-name/oem_dycnvbk of=/sdcard/oem_dycnvbk.img" and then I cleaned it up with QFIL as well.
After that, my IMEIs became 0, but the phone also does not want to receive the network.
I will try something else, if you have any ideas - write.

One solution would be if someone would dump their partitions, particularly a phone that has been locked on Tmo and now is unlocked, then compare to see what's changed..

The only way to currently SIM unlock the T-Mobile version, is with the T-Mobile Unlock app that is a part of the T-Mobile firmware. To be eligible for a permanent unlock, you must meet all of T-Mobile's requirements for the device unlock.

Thanks for stating the obvious.
Personally I'm unable to do that cuz I'm not the original owner..

I think I'm going to hold on to the phone for a little longer to see if someone comes up with a solution.
Once November comes around I'll put it up for sale on ebay. Maybe someone from the US will buy it to use it on T-Mobile.

How about reprogramming the T-Mobile Unlock APP in a way that it will issue an unlock code locally with a PC and not through the T-Mobile servers.

Is this a possibility?

Is there a disgruntled T-Mobile employee who wants to help??? :laugh:

 

[Johnrochasep]

I'm not a programmer, so I don't know what the heck I'm talking about or if this is even possible, but if one of the developers were to get their hands on the full Unlock APP code (or whatever it's called) then wouldn't it be possible to reverse engineer it and have it create an unlock code for the phone without having to go through T-Mobile?

Similar to cracking a game downloaded from torrents, there's usually a crack attached to it that tells your PC it's a retail version.

Any ideas?

i have been working on unlocking mine as well,i have a few theories on how it can be done. the only way is with the t-mobile unlock app. so i started there, i logged all the data that is sent to and from the server with wireshark and dont know were to go from there.The SSL is encrypted or i could see the important parts. also im thinking if they only use the imei to unlock then if it is changed to one that has already been unlocked then the app should work as normal and unlock it.and then just change imei back. i have also tried finding a modem from a gm1917 that is unlocked to just flash it over ours. i think i have tried every possible way.even payed sites. got my money back from cellunlocker.net and now unlock-panda.com is working on it. also had a hacker on Instagram working on it with no luck. he said the server kicked it back saying it was encrypted . i got mine off of ebay it is still tried to a account and has over due bill. Even tried T-mobile twitter and they wouldn't take my money to activate a new account .

 

[Johnrochasep]

That's great headway with the IMEI idea and using the app to record all info going back and forth. Too bad it didn't work.

 

[KewbZ]

Does anyone have any other ideas? What partitions to delete/wipe...modemst1-2 won't do anything...

I figured out the writing part and can change on oneplus 7 pro. With free software lol. Now just trying to get the numbers summited to the server and to see if it will work

Not yet need a imei that's already on a account and able to be unlocked

 

[Ju5t3nC4s3]

Ok. Is there anyone with a unlocked oneplus 7 pro tmobile that can donate a lil time to the community. I need a copy of NV-items back up. I can send the programs and how to do it.If we have somthing to compare with maybe we can come up with a unlock for everyone.
