I have AT&T M8 with WIN10 preview for developers.
I recently ordered unlock code from eBay. Order was processed and in 15 min i got unlock code(s). Two of them to be precise.
Upon inserting T-mobile SIM phone booted up and asked me for unlock code. I typed in first code and got error "incorrect code" and same happen with second code.
I tried each code once more with no success and by that time my counter was down to 6 available tries.
Then I ordered code from different source - HTCUNLOCK.com and received only one code - identical to first one received from eBay purchase.
I decided to try my luck again and rebooted phone with T-mobile card at which point I realized (to my surprise) that unlock counter was back to 10 tries.
My question is did anyone had luck unlocking AT&T M8? What is possibility that WIN10 preview prevents proper code entry? How likely is that two totally independent sources would provide same unlock code (both of them being incorrect)?
Any help or suggestions are welcome, I just want to unlock my phone
Thanks
I sent a request directly to ATT granted the phone i refurbished after it was recycled and given to me. I got an unlock code rather quick. I used two websites prior to going to att's unlock website. One didn't give me a code yet and the other the code did not work. Looks like I'll have to work on getting my money back as the att unlock was free.. who would have thought
I unlocked my AT&T device using this link: https://www.att.com/deviceunlock/
I also ordered a code online (sim-unlock.net) and I got the same code as AT&T sent me.
Cheers, T.
I didn't see this clearly posted anywhere, so I figured I would share.
In the past with OnePlus devices on T-Mobile you were able to call and request OEM unlock even if the phone wasn't paid off. Typically, as long as you were a long time customer they would provide the unlock if the phone wasn't paid off yet. Which got me to thinking, I should try the same thing for my new Pixel 4 XL.
After a few minutes with T-Mobile support chat I was able to get T-Mobile customer support to allow me to unlock my Pixel 4. It took about 24 hours and a restart for the OEM unlock in developer settings to appear. But after that I was able to unlock the bootloader via fastboot with no problem.
Tmobile's policy is that the phone must be paid in full and wait 40 days to unlock. Now you can get lucky with customer service or tmobile on Twitter (this is actually the best way) and get it unlocked sooner but it's just getting lucky. Not everyone will get it unlocked sooner.

At least it worked for you. There's another thread already started with this same conversation only the phones still can't be unlocked after getting an unlock from t mobile
Worked for me, I received the phone early called them and was unlocked in 10 mins. I'm about to return phone though and roll with iphone 11 pro max and note 10 plus. Pixel isn't cutting it.
Really don't need to be unlocked anymore

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:
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 .
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.
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

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.
Doesn't Swappa sell T-Mobile op7 pro that are unlocked?
Has ANYONE been able to submit their unlock token on the OnePlus site? I get invalid unlock code errors. Anyone found a work around? This is driving me nuts. Getting SIM unlock was easy but OnePlus tech support is God awful..
Everybody is facing the same exact issue read here https://www.androidpolice.com/2020/10/26/oneplus-is-having-trouble-unlocking-t-mobile-8t-phones/
Is there anyone who can do this ? I saw someone offering the unlock for free...believe his name on here was mobbdeep?? Service is TMobile, phone came directly from TMobile as well, and have had acount for a few months now.

Sorry bro, he closed that thread a while back. It was legit, he unlocked both of mine. Keep a look out to see if he will do it again. Otherwise you may have to call TMO and persuade them to help or tweet the help desk. Happy modding!
So maybe I can give some help with information. T-Mobile will not allow you to seamlessly network unlock without a full payoff. You can typically contact T-Mobile's Twitter and get them to unlock it if you have a specific reason. According to someone I know directly in their support, they will typically unlock with minimal hassle if you have at least three device payments. However, you can typically get an unlock earlier if you give them a valid reason. A lot of people reported network issues with an OTA. Referencing this, and informing them that a bootloader unlock is necessary for repair, they unlocked mine with literally a single payment on file. It took a bit of persistence (and even referencing the XDA thread), but they did unlock it for me. Give it a shot. Worst they can say is no.

i'll have to give it a try. this is my first tmobile OP variant and i'm already upset that i didnt buy unlocked directly, i just didnt have the full amount up front and really needed a new phone. went with the 8.
Look in the 8+ forums. I just got my 8+ unlocked a few days back. I messaged the person and she got back within about two days. After that I sent her my info and I was unlocked in a couple hours.

Which thread is it in I'm having trouble finding it.
I just called T-Mobile and they approved the unlock for my OP8 (purchased in August 2020). My reasoning was T-Mobile is paying half of the phone (50% off deal) and told them I will be paying my half early (around $230 left). So they said yes to unlock my phone. Give it a try.
What if you buy a T-Mobile locked 8 on ebay? I thought you could still unlock bootloader with msm, am I screwed?

You need to request an unlock token (bin file) from Oneplus to flash before you unlock the bootloader.

Yeah but I bought the phone off of eBay so I don't think they will unlock. I am thinking of paying for an unlock service that costs around $80-$100 (I don't know of any legitimate ones) or returning the phone and buying the n10 5g. The only thing preventing me from getting the n10 5g is the lcd screen, that is a major issue for me.

though you bought it, are you a tmobile customer? I think if the phone is already paid off, and you use the phone on their network for at least 40 days straight, then you should qualify for an unlock.

I got my TMo OP8 off Swappa and just requested the unlock code from the OnePlus website the day it arrived. It took 7 days literally to the minute to get my unlock code, which I hear is the norm.
But also note that we're all talking about 2 different things: a bootloader unlock (which is what I did) and a carrier unlock (which is what OP was after, I believe).

when i checked the oneplus website for bootloader unlock it required an unlock code from tmobile. can you link me to the page where i can request the bootloader unlock?
edit: I am an idiot, disregard that.
Can you help me with getting the unlock token? what exact commands did you use to get unlock code? I followed the oneplus guide but get the response-
"C:\platform-tools>fastboot.exe oem get_unlock_code
FAILED (remote: 'Please enable OEM unlocking in Settings first')
fastboot: error: Command failed"
my understanding is that you need to sim unlock before you can oem unlock.

this is what i had the ebay seller i got my phone from do, and apparently they are going to unlock tonight; the rep said the phone needs to be used for at least 48hrs on tmo network, but preferably 40 days before unlocking. It seems they have an official policy on carrier unlocking and then another policy which is only used on twitter; all very confusing. my concern now is that custom roms will not work correctly on tmo op8t, as verizon owner have reported crdroid not working for them.
Ok mobdeep is back in the game of unlocking TMO phones. Head to his thread and read the info. Happy modding!
So I have an unlocked carrier t-mobile device and I want an unlocked bootloader. Who do I need to contact to get the 7 days rolling? Thanks

If you guys are wanting to root your Tmobile/Sprint phone here is the guide, i unlocked my phone, unlocked my bootloader & rooted it. To get token it took exactly a week. Here are the guides: Android 11 how to root T-MOBILE OP8 5G
TIP: Go into Settings>Wifi&Network>SIM&Network:> Network Unlock. This should get your phone unlocked which is the first step. Then head over to unlock token - OnePlus (United States) and apply to get your token, which took me 1 week exactly. Here is also a tool incase you brick your phone: Unbrick tool to restore your device to OxygenOS
