2. Unlock bootloader

3. Use the fastboot erase modemst commands to remove sim lock

I already have my token
[OnePlus 6T  Guides, News, & Discussion] Cablespider:
Another sucess story.

Converted over the weekend, ran the commands and used the international version for a bit. MSM back to stock TMO today. I ran the unlocker app and it showed fully sim unlocked. Generated an unlock code and applied through OnePlus. Back on INT for the time being while waiting for the bin file. Awesome! Thanks!

i have unlocked my bootloader, am receiving OTA beta updates, and bought a dual SIM card replacement and am using two T-Mobil SIM cards perfectly.

Question:

How do I reset / wipe my phone but keep it unlocked, stay on beta, use dual SIMs, etc...?

Can I use the factory restore option in the stock recovery safely?

Or can i use the reset option in Android's Settings menu?

Thanks..

So, if I understand this correctly, we can use this method to trick T-Mobile and oneplus into gibing us an unlock token even tho the phone isn't paid off?
[OnePlus 6T  Guides, News, & Discussion] :
Yep, actually it's not a trick, it's just how they do it, minus their software for remote sim unlock. This backdoors it
[OnePlus 6T  Guides, News, & Discussion] Scott:
We should decompile there unlock program to see what it does. It bet it does the same thing that this method does.

i successfully convert to the specified rom but oem unlocking is greyed out. i cant unlock bootloader. please help me with solution
[OnePlus 6T  Guides, News, & Discussion] Vortell:
You should probably go to the link and then either ask a question there or better yet use the search function.
[OnePlus 6T  Guides, News, & Discussion] :
It's all in here. Read the thread. First few pages I explained this in this thread and the original convert thread
[OnePlus 6T  Guides, News, & Discussion] Vortell:
I mean kind of but the link in the thread to the msm thread explains it clearly and still the best method in either thread is to use the search function.... The word "Greyed" is only here two other times. Hence my suggestion he goes to other thread linked in op to learn the basics of unlocking bootloader first. ;) I was one of the first people who asked about this in that thread though! After you started to explain it.
[OnePlus 6T  Guides, News, & Discussion] :
First bootloader unlock with msm 9.0.11. then fastboot erase modemst1 and then fastboot erase modemst2, now simlock is off in the hardware for good. Then simply copy the patched msm factory.exe to every new msm tool directory and u won't have oem unlock greyed out ever again.
[OnePlus 6T  Guides, News, & Discussion] Vortell:
Haha. Mines been done the whole time. With twrp and mods! Maybe you thought I didn't get it? Only thing I'm confused about in Android right now is the new twrp install method. They talk about ramdisk install using a .img but it wasn't in the flow of installing zips, it was in another area. So you would have to install zips, go to main menu then go to a different sub menu and install twrp again. I was waiting for next twrp to see if it was stream lined. Unless I missed something which seems probable after the fact.

[MENTION=8360749]partcyborg[/MENTION] Here it is... Yeah... Better late than never... Forgot about this thread...

But here is the apk download from APK mirror. The original download link is here: https://www.apkmirror.com/apk/t-mob...se/device-unlock-1-2-31-android-apk-download/

I would be, as well as most others, curious to see what you find that it does.

Sorry for this noob ask, how do you backup partitions using readback mode. When I open up MSM download tool, all I see is two option- Download and upgrade. Is download the option for backup?. Thanks in advance
[OnePlus 6T  Guides, News, & Discussion] jamescable:
So. I financed this phone. But its not fully paid off. Cab I use this to switch to another carrier even tho T-Mobile will blacklist it? Also, does using the msm tool remove this?
[OnePlus 6T  Guides, News, & Discussion] TKruzze:
Sure sounds like you're trying to steal this phone without paying for it. Without information to the contrary, I hope nobody helps you out...
[OnePlus 6T  Guides, News, & Discussion] jamescable:
Wow your a ****!! No I'm not trying to steal the phone. I paid all but $50 on it and can't afford T-Mobile service anymore. Going to prepaid or straight talk...I paid $500 and something on it already, so no...I'm not trying to steal it, but thanks for assuming people are horrible, you just made an ass out if yourself
[OnePlus 6T  Guides, News, & Discussion] Scott:
The answer is yes. This is a SIM unlock thread and following the steps provided will unlock the sim to be used in any carrier.

T-Mobile will black list the phone unless its paid for.
[OnePlus 6T  Guides, News, & Discussion] jamescable:
Will using msm tool revert this? Like, if I use it but don't go back to T-Mobile ROM to to use unlock app and stay on custom ROMs but have to use msm tool to reviver phone down the road, would it revert this
[OnePlus 6T  Guides, News, & Discussion] Scott:
Once unlocked it cannot be locked again by MSM Tool. Only way to lock it again would be to back up the partitions and then re-apply them when you want to lock it. Something that would make no sense.

So... Once unlocked SIM always unlocked SIM.
[OnePlus 6T  Guides, News, & Discussion] vnphantom:
No. Find the previous owner. If not, turn it into your nearest police station and they will find the rightful owner. It is 2019. Lost and stolen phones that were properly set up and secured cannot be used by anyone else that is not the rightful owner.
[OnePlus 6T  Guides, News, & Discussion] Danny1976:
Was asking because there are a couple of OnePlus 6T on eBay selling cheap, because of bad IMEI. But I decided it's not worth it if they are blacklisted and can't be used with any US Carrier.
[OnePlus 6T  Guides, News, & Discussion] Tech_Savvy:
I bought one..it's blocked by TMobile but I called att and they say it currently good with them..swappa esn check also said it clean....I think TMobile never blacklist em...bought my wife a financed lg g5 2 years ago and it still isn't blacklisted
[OnePlus 6T  Guides, News, & Discussion] Danny1976:
So, get the IMEI number and check on swappa and contact ATT to see if it's blacklisted on their system? If you don't mind me asking.... How much did you pay for yours on eBay and did it include any accessories?
[OnePlus 6T  Guides, News, & Discussion] Tech_Savvy:
That's what I did....but it's not guaranteed to stay clean though....but I can change it if push comes to shove...or get a dual SIM tray from eBay and use the second Sim slot which wud have a clean imei...win win.... I paid 230 on eBay...great condition..no accessories..but got 23 dollar eBay bucks to boot:)
[OnePlus 6T  Guides, News, & Discussion] Danny1976:
That's a steal... I thought the one listed now for $279 was a good price, but compare to $230... Not so much.
[OnePlus 6T  Guides, News, & Discussion] Tech_Savvy:
Well I messaged wit an individual and convinced him to it:) they go for around 280 now...which 8s still amazing compared to what u get
[OnePlus 6T  Guides, News, & Discussion] Danny1976:
Just remembered TMobile IMEI is the same on both slots. The only way would be to change the IMEI, but that requires special equipment.
[OnePlus 6T  Guides, News, & Discussion] Inujoshua:
can you help me

hey i have a tmobile oneplus 6t converted into international .but my sim is locked..please teach me the process to unlock
[OnePlus 6T  Guides, News, & Discussion] engMTW:
Actually not true. On the 6t, after wiping the Tmo modem storage partitions (and running international rom, obviously) it has two IMEIs.
[OnePlus 6T  Guides, News, & Discussion] Danny1976:
I have done the international conversion on a 6T before and both slots have same IMEI. What I did was delete the two modem files modemst1 and modemst2. What did you do to delete the modem storage? Did you do it through TWRP advance wipe?

[OnePlus 6T  Guides, News, & Discussion] I<3cats:
Could you elaborate on this? I've done the steps from this thread. I'm on international rom and have my sim unlocked successfully, but show the same IMEI for both slots.
[OnePlus 6T  Guides, News, & Discussion] jestyr8:
It will show the same IMEI until both sim slots are occupied is what I've been reading. But I could be wrong. Several people have been using 2 Sims without issues depending on the carriers being used
[OnePlus 6T  Guides, News, & Discussion] engMTW:
Bingo. You gotta actually put in two sims. They don’t both have to be active, just present.
[OnePlus 6T  Guides, News, & Discussion] Chad The Pathfinder:
I've been successfully using a T-Mobile sim along side a Ting sim to have 2 different numbers but I just looked in settings/about phone/status and it shows 1 imei. Both numbers work correctly though.

Hola, tengo un oneplus 6t con bloqueo temporal, ¿será que este procedimiento lo desbloquea permanentemente? gracias por tu respuesta.
[OnePlus 6T  Guides, News, & Discussion] 1337n00bi:
My guess is that the imei is blacklisted on the network of sim 2
[OnePlus 6T  Guides, News, & Discussion] MarlyAC:
Correct process

I did the process, dual sim working correctly. My question is the following

when I was in T mobile rom, I had the temporary unlocking (until August 17), with this process the sim will be permanently unlocked?
[OnePlus 6T  Guides, News, & Discussion] jestyr8:
Yep.. I did the temp unlock.. then found this Sim unlock guide.. did it.. reverted back to TMO version and the TMO unlock app says it's already unlocked. I then did the official boot loader unlock process just to have my token just in case
[OnePlus 6T  Guides, News, & Discussion] R800x_user:

[OnePlus 6T  Guides, News, & Discussion] dgafking0480:

Use the patched msmtool for 9.0.11 to got to that version. Oem unlock will be enabled. After that you can unlock and after that you can do local update to get to 9.0.16

You can use the same step when you convert from T-Mobile OS, but this time use the OS 9.0.11. They oem unlock should work.

[OnePlus 6T  Guides, News, & Discussion] ipdev:
lrwxrwxrwx 1 root root 15 1970-02-05 08:04 modem_a -> /dev/block/sde4

lrwxrwxrwx 1 root root 16 1970-02-05 08:04 modem_b -> /dev/block/sde32

lrwxrwxrwx 1 root root 15 1970-02-05 08:04 modemst1 -> /dev/block/sdf2

lrwxrwxrwx 1 root root 15 1970-02-05 08:04 modemst2 -> /dev/block/sdf3

Backup partitions using dd and adb shell.

adb shell dd if=/dev/block/sde4 of=/sdcard/modem_a.img
adb shell dd if=/dev/block/sde32 of=/sdcard/modem_b.img
adb shell dd if=/dev/block/sdf2 of=/sdcard/modemst1.img
adb shell dd if=/dev/block/sdf3 of=/sdcard/modemst2.img
adb pull /sdcard/modem_a.img
adb pull /sdcard/modem_b.img

adb pull /sdcard/modemst2.img
adb shell rm /sdcard/modem_a.img
adb shell rm /sdcard/modem_b.img
adb shell rm /sdcard/modemst1.img
adb shell rm /sdcard/modemst2.img

Radio would be

lrwxrwxrwx 1 root root 15 1970-02-05 08:04 oem_stanvbk -> /dev/block/sda9

adb shell dd if=/dev/block/sda9 of=/sdcard/oem_stanvbk.img
adb pull /sdcard/oem_stanvbk.img
adb shell rm /sdcard/oem_stanvbk.img

Note:

I have not fully looked into my 6T yet.

(Only full updates and a quick partition dump.)

Radio (oem_stanvbk) may need to be a .bin file instead of .img file.

If you can not fastboot flash them back, you can boot into recovery (TWRP) and restore them using dd.

(dd if=/sdcard/modem_a.img of=/dev/block/sde4)

Cheers. :cowboy:

Unlock T-Mobile

Hey guys,

So I have done the rebranding on my T-Mobile OnePlus 6T but the phone is still locked on carrier now I have requested TMobile to unlock my mobile and they have said they will send me an email with the instructions to unlock it which is good news. But when my phone was rebranded all the T-Mobile apps have gone and I downloaded the unlock app from one of the forums here at xda but when I open and try to move forward the app says "this application is not compatible with this device". My question is when TMobile will send me the instructions how will I unlock my carrier won't it require me to go thru the T-Mobile unlock app ??

Please help!

Ok, i had the exact same question when I wrote my thread [T-Mobile / Guide] - Full SIM and Bootloader Unlock + Root for locked devices.

I came to the conclusion that deleting those partitions is the same as unlocking from T-Mo.

How did I test this? Took a long time. Trust me, they are the same process. When you "unlock" with T-Mo you do nothing more than "erase" those same partitions (modemst1 and modemst2).

Hope this helps!

Thanks!

it'll probably drop to $800 or less quite soon after (£400)

it's 'cheaper' with a contracy usually though, free or very cheap (>£100) with contacts <£35/month, that also includes all your calls/texts/internet so it can be quite good.
