[robbie1104]

I've finally did the process and it WORKS PERFECTLY, sim unlocked, no ime issue... data working correctly, everything works perfect.

I'm very excited, let me get a refund from cellunlocker and donate you some money

Could I lock bootloader again?

Thank you nika_bego

This is similar to how SIM unlock was gained on the Sprint Essential PH-1.
The modem and setting files were copied from a SIM unlocked version. This unlocked the SIM on the Sprint version.

Sprint was making people wait months and giving them a hard time even after the device was paid and the waiting period was over.

Good job.

Moto z had a magisk mod to do this also but just need to have msm tool to recover just incase

Yeah, I remember you back then. We both had hard times getting our Essential phones unlocked after the 50 damn days waiting period over. I had to contact Sprint customer relations VP to get it resolved. What a nightmare!!! Never Sprint again!!! I still have it though but gave it to my son and he likes it.

If u guys try the TMobile unlock app it still says network locked, but if u check under engineer codes simlock will now say off. Trying to do this backwards to see if we can relock,, just for kicks


Edit.. yes if u wish for some strange reason to re simlock your phone, reboot bootloader and
fastboot flash modemst1 modemst1.bin

Then same command but with 2 for the second one..


This is after backing it up to an external source somewhere after dd'ing your modemst1 and 2


Then reboot, simlock is back on. And then u can do this back and forth furthermore, thanks nika

If you don't want modifications in system you can lock bootloader or just left as is
Cool it's way faster than any service for unlock

Bro ur funny we use magisk n we don't dd modems thru terminal to back anything up.... Tell me technically what sense would it make to delete your modem how would that unlock your sim?

Your not deleting the modem. Your deleting the storage of the modem, modemST.

Hi, I believe you, and I want to try this method... but where are the source of your information? How did you know puting those comands will work?

Thank you!!!

Its all over the internet. No for real. Just google modemst1 or modemst2. I did when I saw this and realized he is correct with what he posted.

Or better yet.... https://www.google.com/search?q=mod...0j69i60j0l2.1471j0j4&sourceid=chrome&ie=UTF-8

Modemst1 and 2 is settings, not modem.

This!

If the T-Mobile App says your still locked, could you tell me if Developer Options allow Bootloader unlock?

The only reason I care is I want to run the T-Mobile ROM but maintain root.

Can someone please explain me but more detailed in how to do these steps, I'm not a tech guy as you can see and this is the first time I own a OnePlus phone and I really want to unlock my 6T

 

[KaM1KaZ3]

Hi again, just one more question: How did you root the device (to make modem backup) with locked bootloader??

A Paperclip and rubber band. :silly:

Yeah I was standing on my jump to conclusions mat because it sounded too easy. It seems a bit like a bypass vs a true sim unlock (that registers with the carrier as being unlocked) as I'm quite sure this doesn't fly in the actual tmo oem stock that has the tmo unlock app but not like that matters too much for most... Kudos Nico and sorry for doubting! I do wish the people that discovered this in Nov would have shared it so I didn't have to spend 3 hrs working my way up the chain of command talking to TMobile on the phone and in chats just to get denied after explaining I needed it sim unlocked and giving various reasons why then finally succeeding with unlock via the tmo Twitter support... seems like a huge avoidable waste of time now lol. Not sure why people would keep something that many people struggle with to themselves it's bad enough how Google just caved into all the carriers for pie n gave them more control over us

Yep. As soon as the 6T was announced with Verizon compatibility; it was on the shopping list.
I bought mine unlocked, so not carrier drama.

I sold the Essential on Swappa for more than I paid.

 

[XJonathanX2]

This method worked like a charm!! I converted to the international version with no problems and manage to unlock my 6T easily, now I'm rocking with my sim card no problems!! Thank you so much Niko I really appreciate it!

 

[cangri87]

This worked great! Just tested it with a AT&T sim and low and behold i had service.

I am wondering now, if i revert back to stock if it will remain sim unlocked or will the flashing back to factory
rewrite the modemst files?

 

[pyrorob]

Has anyone thought of comparing dumps of a before and after using a hex editor or beyond compare or similar utility? Would be best if someone compared a dump of an proper sim unlocked device, but it might be interesting to compare using this method as to see if anything is written to those partitions after deletion..

If you flash stock it will be sim unlocked you need modemst1 and modemst2 backup after sim unlock you can flash this files and it will be sim locked again

Thank you for your help and work to get us here. I bought a 1+6T on Offer Up and it worked for a couple of months but when the original owner did not pay for it. It locked my phone. This helped and let me not lose money on my investment.
