OnePlus 7T T-Mobile Conversion - OnePlus 7T Questions & Answers

I got a few 7Ts from T-Mobile about a month ago. I was able to get the first one unlocked from the free SIM unlock thread, but it's shut down now. Is there any way to convert a SIM-locked device? Any progress on the MSM tool? I'm willing to try third party unlock methods as well.

T-Mobile charge £20. Also, reading on the internet, many are having probs getting the code from T-Mobile - waiting months and when code arrives does not work, etc... Don't really want to go through all this hassle with T-Mobile and also pay them £20 to mess me around.
Is there any way to network unlock the HOX without a code ???
Take it to a t-mobile store
I was on T-Mobile UK and sim unlocked it the day I bought the phone. The code worked on stock ROM. I'm using the phone on Vodafone now.

Flash ATT firmware on Verizon

Hi
I have been able to flash the unlocked non carrier specific firmware on several Verizon Samsung phones over the past few years. Through my employer, I was able to get a free Motorola One 5g UW that I want to take and use on ATT. I know it has the antennas. I can put my sim in, and it shows cricket, but it is locked through Verizon. Is it possible to flash a Motorola from one carrier specific firmware over to another like the Samsungs ? Verizon says it will unlock after 60 days, but even still, it will have Verizon bloatware on it. Thanks in advance.
It doesn't work
Radio in AT&T and VZ versions are different.
Moreover, both bootloader are dead locked and there's NO WAY to unlock

Oneplus 7t T-Mobile Carrier Lock

Hey Everyone!
I was fooled into buying a Oneplus 7T, 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.
I tried using the T-Mobile Device Unlock app but it did not work. (Some kind of error message)
Is there any way to unlock the phone since all i have the imei number of the phone only
Also sorry about this being my first post
Hopefully there is a way to unlock the carrier
Unfortunately you can't bypass this, so to unlock your device you have to request it from T-Mobile if you meet the requirements.
OR You can follow this thread and your new best friend will unlock it for you.
On a side note: Learn how to search, that way you save yours and others time.
Or convert to Global via hacked msmtool and everything unlocked

In a phone that is SIM-locked, the firmware needs to find a specific pattern in a portion of the SIM card's identification number (IMSI). This portion of the IMSI identifies the country in which the SIM card was issued and the service provider which sold the sim card.
If these do not match the specific country and/or service provider to which the phone is locked, then the firmware will refuse to use the SIM card.
If the firmware includes a SIM-lock, generally the ROM is powerless to do anything about it. And to unlock it you need to follow a specific procedure that network operator or the phone manufacturer offers.
That's why the phone will remain SIM-unlocked even after you switch to a different ROM.
From the above you get that the lock exists in the firmware, not in the ROM.
Maybe my phone was not locked at TMobile central and only at rom level. I'm just happy I can use non TMobile provider for cheaper cost (Mint mobile is $20/mo for 10gb data and unlimited talk/text). I couldn't before converting as it rejected non TMobile sim, but could afterwards
Please any help on how to sim unlock my Tmobile oneplus 7t? Third party unlocks are too expensive for me. Unless anyone knows a cheaper unlock service below $30?

Mint uses T-Mobile towers. So a T-Mobile device doesn't need to be SIM unlocked, in order to use Mint.
The same goes for Metro or any other carrier that uses T-Mobile towers
Not possible unlock

Any Guide to Unlock Bootloader or Change the Official ROM to a different one?

Hi there, so about few months ago like back in August, I got myself an LG Wing after LG announced that they were going to close the mobile division. I live in Malaysia and I asked help from a friend in India to help me get one and send it over.
After getting it in my hands, and after I inserted the SIM, it says Network locked. I bought the phone unlocked but it turns out, the phone needs to be used with a SIM from the same country, perform a 30 minutes call and then it would become unlocked.
Given that I stay in Malaysia, its impossible for me to travel all the way to India to unlock a phone. That said, is there any way I could perform either one of the following?
- Get the Unlock Pin to be able to use with other network?
- Change the India Official ROM with a different country ROM perhaps?
Thanks!

Currently no method (yet) to unlock bootloader and install ROMs or GSI images, unless you get lucky like one member did here and get a demo model that's already bootloader unlocked from factory

What are the steps to root a demo model? I am thinking to buy a demo model. It seems cheap.

You don't, unless you hopefully get lucky and its factory bootloader unlocked. There's no way (yet) to unlock the bootloader to root every lg wing, demo or not
Don't buy a demo model unless its just a phone to play with. Not a good every day use phone

How To Guide LE2127 TMobile To EU One Click

Some quick tips what I did to my new OP9 Pro Tmob LE2127 on CE22 firmware here in Canada! Picked the phone up a few days ago and loved it right away but hated all the Tmob crap they installed. Tried converting with the Fastboot method and managed to brick the phone as I'm running Linux and its a little more tricky if your not a Linux pro! It unbricked very easily with the MSM back to Tmob tool and an old laptop on Windoz 10. Make sure setup the HUSB Qualcomm drivers properly! Than some reading and realized you can only go from TMob to EU rom with the MSM tool. Tried that worked perfectly the first time did all the subsequent OTA updates all the way to the current Oxygen OS 13 & Android 13 and its working perfectly. At first there were some weird SIM modem dropping and data issues but as I upgraded to newer versions of Oxygen it cleared it self up. Still says two sims in the mobile network area but identifies them correctly also the phone identifies as a LE2123 now! I also didnt unlock my bootloader but I did get an unlock.bin just incase that process took only overnight, I submitted and recieved the Unlock Bin the next morning it shows up in your One Plus account and you download it! Hope that helps some one out and issues I will report back! Phone is very smooth now!

Are you gonna try any custom rom? If so, can you tell me your experiences whenever you decide to install custom roms?

I'm on the fence about that right now the phone is running really smooth and fast I will give it a few days see how it goes!
I received (another and hopefully final) my op9pro the other day. Powered it up and noticed the OEM unlock was in blue and it still is after updating to the latest version. T-Mobile is giving me a hard time on getting my SIM unlocked. Probably because I bought it from Amazon. Want to attempt but I have seemed to have forgotten if root is still achievable with Sim being locked. Sorry been away for a year, you know iphone things.(throws up in mouth). Good phones though for battery life
If anyone has a locked sim,converted and rooted,please do tell if it is possible I don't need the steps,just confirmation that it works. Thanks

It's 100% sure, possible. I immediately converted my 9pro to Eu on day 1, while sim locked. I bypassed the toggle with a tool in the forum but there's also an adb command available for making the oem unlock toggle work.
This includes root and unlocked bootloader while sim locked.
The thing to be aware of is, the T-Mobile variants have a different bootloader unlock process vs non carrier variants. You submit an unlock token to OnePlus and get an unlock bin back, then flash that bin. Lately, people have been reporting the site is broken and they're using support email/chat to submit and get the token. However, this different process can also be bypassed:
Right after you do the Tmo->Eu msm conversion, it's advised to unlock the bootloader on Android 11. Android 11 on Eu will not need the unlock.bin to unlock the bootloader. But it is needed for later versions so if you want bootloader unlocked, do it right after conversion while still on A11.
The "problem" is, once you do this, if you want to sim unlock the phone later, you have to go back to stock Tmo firmware with the stock Tmo MSM tool, as the built in unlocker is not in Eu or other variants. Which means you will have to wipe data later whenever you want to get it unlocked.
it took me 6 Agents at Tmo chat support to finally get the unlock handled properly. One agent asked me to submit my proof of purchase and I did but they couldn't figure out how to unlock it because of the imei starting with 99 and they only know how to unlock imei starting with 35. Thankfully someone else did know how and they got it sorted after a week or so. Some agents told me it needs to be on the network for 40 days, some said they can't do it because I didn't buy it from T-Mobile, some said I need to wait longer. None were true. I told them I'm a developer and needed to unlock my bootloader to test things for my job.
Here's a link to the tool I used for making the oem unlock toggle work despite sim lock: https://forum.xda-developers.com/t/...ader-unlock-enabler-engineer-decrypt.4380419/

I'm sure its possible. If someone wants to get you up and running. But honestly, it's better to learn it yourself in case something happens and you end up without a phone cause you didn't want to learn. It seems rough but once you get it you're golden bro. Tough it out and smash them wires in the phone/computer, and open a terminal and tap away at the keyboard. If all else fails, slap the phone and)or computer around and show em who's boss
I personally had to go to AA as BA/EU was giving me a nightmare of a time with data
Just an update on my 2127 Tmob to 2123 EU conversion! Its working flawless guys I didnt bother unlocking the bootloader when I did the conversion even though I do have the unlock bin. It only took overnight to get the unlock bin this was a few weeks ago! The phone now is working really good everything is flawless still on a locked boot loader which is fine its working smooth and taking updates another OTA update came today! Running A13 Oos 13 LE2123_11_F74.
Which version of MSM tool is best for this conversion?

Yes everything is working good!
Question:
1.Enabling dual sim will add another IMEI to the device, so the original IMEI is duplicated or you get a new IMEI for it? In my country duplicate IMEI's aren't allowed hence asking
2. I remember there was a dual sim patch for OP8T and there were rumors of losing dual sim capability after update is that the same here?
