1 phone is not stolen its financed ordered from ebay as unlocked I was scammed was not able to return from oversies

2 you can backup your modems and then try deleting with this commands they are not deleting I tryed 2 times

3 after blowfish confirmed that phone was unlocked opened unlock app > permanent unlock was receiving same error delleted app data same error factory reset - same error reflashed firmware same error after that this commands worked
[OnePlus 6T  Guides, News, & Discussion] GuestK00321:
all unlock services included blowfish unlock cellunlocker few one from ebay . tyed many of them they refunded money (blowfish returned credits to account) main reason wan device was not active 40 days this services can unlock bad imei phones but if device was not active 40 days they can't more than month I was trying to unlock but only this commands worked if you think you will loose modems to backup try this method

Download & Open up Terminal Emulator on your phone

Once it's open you'll be greeted with a command line prompt, in which you can enter text commands, the first thing you need to do is enable root access by entering this line (press the enter key on your on-screen keyboard after each command to issue it):

Code:

su

If this is the first time you've used Terminal Emulator a Superuser or SuperSU popup will appear, make sure you grant root access.

Now enter these two commands:

Code:

dd if=/dev/block/sdf2 of=/sdcard/modemst1.bin bs=2048

Code:

dd if=/dev/block/sdf3 of=/sdcard/modemst2.bin bs=2048

Hi again, just one more question: How did you root the device (to make modem backup) with locked bootloader??
[OnePlus 6T  Guides, News, & Discussion] GuestK00321:
I didn't backup modems copied this first found instructions for annoying users ?
[OnePlus 6T  Guides, News, & Discussion] GuestK00321:
Before phone turned on I was searching modem files I was ready that phone doesn't turns on. But everything was good i don't lost my imei and phone is sim unlocked
[OnePlus 6T  Guides, News, & Discussion] GuestK00177:
Some people I know discovered this work around in November if u make a modemst back up of both modems first, use msm readback to backup imei, then wipe modem, then sim unlocked, restore modem files and imei with msm readback mode. It's just very risky. So if u know how to use msm readback mode and smt mode then go for this, [MENTION=4749890]nika_bego[/MENTION] you are correct. For the haters, grow up man, u are incorrect, this man is correct. There are multiple ways to do things in android. I was part of the initial team that first achieved root with this phone with a locked bootloader via aging kernel. Which then led to wiping the modems..we had to keep it between ourselves or chaos would erupt on xda. Plus the mods get so upset if u talk about hacks, modded apps, imei anything and restoring stuff.

Thanks, good job man

Modemst1 and 2 is settings, not modem.
[OnePlus 6T  Guides, News, & Discussion] kramer987:
can confirm same.
[OnePlus 6T  Guides, News, & Discussion] sandix:
I don't believe this guy either. However it is actually true that converting the TMO variant to the International using this: https://xdaforums.com/oneplus-6t/how-to/t-mobile-6t-to-international-t3888307 will allow a simple

fastboot oem unlock

instead of having to go through OnePlus/TMO to get unlock.bin file.

Doing the conversion, then unlocking the bootloader, then rooting as normal. However I do not for one second believe that erasing the modem will unlock the SIM.

Edit: Looks like it might be possible to SIM unlock with this HOWEVER it requires MORE STEPS not only what is listed in the OP.

OP - Can you please update your post with a full, detailed list, of what to do?
[OnePlus 6T  Guides, News, & Discussion] robbie1104:
It is really necessary to unlock bootloader first?? I flashed 9.0.12 and OEM unlock under Developer settings is grayed and disabled... Do i have to flash 9.0.11 to unlock OEM?? In what version of OxygenOS did you make this procedure??

U gotta use readback mode on msm to back it up first. Then wipe smt wipe it then use it to restore the modemst. A and b and then u have to restore imei. A quick Google search will help u with that

[OnePlus 6T  Guides, News, & Discussion] Milly7:
You enter those commands while in the bootloader. The same place where you enter the commands to oem unlock the device.
[OnePlus 6T  Guides, News, & Discussion] swiftbones74:
It's already very clear adb to fastboot. It's a fastboot command and if you don't know what that is you need to do more research before you start using it.

Are you still on T-Mobile firmware? That is the only thing I can think of that would give you that error. I've done this procedure a few times without any problems like this?
[OnePlus 6T  Guides, News, & Discussion] Honkytony:
How likely is it for this method to brick my phone? I have two one pluses that are both paid off but t mobile is taking forever to get back to me. I’ve already used this method to unlock one phone. The other is still carrier locked. My plan is to sell both but I don’t want to sell a phone that’s most likely going to get bricked. Any info would be great!
[OnePlus 6T  Guides, News, & Discussion] meranaamjoker:
I was cheated- someone sold me blocked 6t

I never thought I would get into something like this. Somebody on cragislist advertised 6t as 6 and I sent my friend to pick it up as its near to him. Given 6 was never sold through carrier in US, I was sure it would be unlocked. So I asked my friend just to check visually, then wifi, then if its charging or not.

OMG! this phone turns out to be 6t and its blocked by T-mobile as it was reported as stolen. The seller now disappeared. His phone no is not reachable.

I am confused with multiple threads on xda whether this process will (1) sim-unlock this phone or not? Sim-unlock is fine for me even though its blocked in US. I am hoping i can give it to my father in India where this sim-unlocked one wont be blocked by Indian carriers as well. I am using it right now just on wifi.

Thank you so much in advance really. XDA is the only hope I have now on this phone.

What? could you SIM-unlock your phone with this approach? Thats awesome. Then what is stopping you to repeat the same on the other phone?
[OnePlus 6T  Guides, News, & Discussion] NexusS4gFreak:
I got sold a locked phone (scammed) and tried this method after unlocking my bootloader but when I put in my sim after deleting the modems my phone will show a signal at first but then lose signal bars and say sim not allowed in the notifications. Like it did before I did the fast boot commands

For clarity, i was ok stock 9.0.17, converted to international 9.0.11 then ungraded to 10.3 and did the commands while I was on 9.0.17 and 10.3

I tried this, and I'm still getting the 'SIM 1 not allowed'.

I'm still paying on the phone from t-mobile, but a friend of mine's phone died, and I have a Note 10+, so I wanted to let them use my oneplus 6t. They have MetroPCS. The phone isn't stolen or blacklisted, it works fine with my t-mobile SIM. I just want to let my friend borrow my phone!

The phone is on OxygenOS 9.0.11 after I did the 'flash international to unlock the bootloader' bit. The bootloader is unlocked. I run the commands, it says they succeed, but the phone still won't recognize the SIM. What am I doing wrong?

Have you checked the apn settings, also metro needs to add the device to there system using the IMEI. That's why it doesn't work immediately. Any other gsm carrier would work.
[OnePlus 6T  Guides, News, & Discussion] heldc:
Ah! That was probably the problem, metro not having activated it. What I ultimately ended up doing was shuffling the phones differently. Gave the one+ 6t to my roommate, who is on my t-mobile plan, and got their paid off phone sim unlocked and gave it to the friend.

What if we flashed the modem from a carrier unlocked phone to a locked phone would that unlock the carrier
[OnePlus 6T  Guides, News, & Discussion] mine420:
Follow steps in post #1 and it should work did on my t mobile 6t
[OnePlus 6T  Guides, News, & Discussion] mrhodes19904:
I was referring to the OnePlus 7 pro converted to international. I tried flashing a back up modem and modemst1 and st2 from gm1917 unlocked and it did not work
[OnePlus 6T  Guides, News, & Discussion] R800x_user:
Well typically once you unlock your sim on the TMobile variant it gives you the option to unlock the bootloader. When you do that, the phone would need a unlock token sent to OnePlus which in turn would need you to wait a while week from the time you send the request. After that you can officially unlock the bootloader and convert to international. So theoretically you should be sim unlocked without the need to restore a modem. Unless you messed up and wiped your modem st1 and st2. If you did that you might need to use the msmtool to restore your device again. You can also try fastboot ROMs to restore to stock modems by only flashing the modem st1 and st2.
[OnePlus 6T  Guides, News, & Discussion] moccor:
I am confused, so is this for unlocking a TMobile Oneplus 6T bootloader without going through all the extra unlock steps? Jw, I have had my OP6T for over a year but I am on a plan with friends and didn't wanna bug anyone to have it unlocked just for custom ROMs. I've used the international unlock method before but now I wanna use LOS17 with the the Tmobile stuff so GPay works
[OnePlus 6T  Guides, News, & Discussion] mine420:
This is as the title says for sim unlocks not boot loader unlocks. To unlock bootloader for T-Mobile variant use the guide where the title says convert to international ROM.
[OnePlus 6T  Guides, News, & Discussion] apolo512:
Somebody has tried to flash modemst1 and modemst2 of other unlocked phone?

I'm asking because I have a oneplus A0001 broken that I won't repair it, so I have a GM1915 bootloder unlocked, but I don't know if that is possible, I think is too risky.

I hope somebody with experience try that.

TMobile sim locked with android 10

HI.

I have read all the thread, and it looks like a piece of cake to do this, but i have one question.

I have recently received a used Oneplus 6T, which came with android 10 , it is from T Mobile. Do I have to do something different in order to make it work on this device? it looks like this procedure was made whit android 9 installed. because i was thinking on doing all this procedure, but i don't know if I could make a soft brick or even worse a hard brick..

Any suggestions?

Thanks in advance

---------------------------

Update 1:

I have found here on xda a step by step guide :

https://xdaforums.com/oneplus-6t/how-to/guide-sim-bootloader-unlock-root-t3921795

'cause everything was mixed up and could not find a real path

Finally I have decided to be a daredevil, and follow up the instructions provided, so far, so good, I have downgraded an android 10.0.3 T Mo oneplus 6T to International oneplus 6T Android 9.0.11

Have enabled dual sim cards with the same IMEI number. So lets move on the next step :)

Update 2

Have done everything as described to sim unlock the oneplus 6T. and voila!! it just WORKS!!!! just can't belive it would be so easy :S

Thanks a lot for your help , :D
[OnePlus 6T  Guides, News, & Discussion] spamolamo:
Will this work if you've already installed a custom rom? Do I need to reflash the OnePlus firmware for the sim unlock to work?
[OnePlus 6T  Guides, News, & Discussion] soaragon:
What I have read on all the posts around XDA and this device, you have to reflash the original T Mobile firmware, make all the steps as described, sim unlock the device, and after that you can install whatever rom you like.
[OnePlus 6T  Guides, News, & Discussion] blushrts:
I'm a customer on Metro PCS and bought the tmobile version from OnePlus in February. For sh**s and giggles I followed the steps on tmobile's website to sim unlock the phone.

That didn't work also, I have found a way to do it and have the sim unlocked just now trying to get it to register on the network. I got the firehose extracted from the .ops file and I can now manage all the partitions.

Hey guys, trust we're all doing good. Pardon me, but I got the 1+ Nord N10 5G T-Mobile variant (purchased on Ebay) and I have TWRP'd, Global Rom'd, Bootloader Unlocked and Rooted it.

Since I'm in Africa, I have no option than to unlock the SIM Network so I can use a local sim but following the thread's instructions on 'erasing modemst1 and modemst2', it appears this is not possible (or at least for me) on my Nord N10 5G.

Feedback from fastboot when I use the erase command:

C:\Users\E4TLESS\Downloads\platform-tools_r31.0.2-windows\platform-tools>fastboot erase modemst1

Erasing 'modemst1' FAILED (remote: 'Erase is not allowed for Critical Partitions

Newer devices using fastboot will also have "fastbootd".

Critical partitions have to be flashed in fastbootd mode.

If booted into system, you can reboot into fastbootd with adb.

adb reboot fastboot

If booted into fastboot (bootloader).

fastboot reboot fastboot

adb reboot bootloader is normal fastboot.

I entered the command as you said and phone initially rebooted the TWRP recovery which displayed an 'Entered Fastboot mode. . .' screen with two options to Enable ADB and Reboot.

Since connection to ADB Console on my PC was lost at this point, I hit Reboot and then did an ADB Reboot Bootloader after which I then did Fastboot Reboot Fastboot and now TWRP is bricked, completely inactive, on the 'Entered Fastboot Screen...'

I can't even restart the phone as pressing power button only and with volume combos does nothing...

Was the TWRP 'Entered Fastbood mode. . .' (even though unresponsive, in my opinion, right?
