I can say if your phone is unlocked by TMobile then converted to EU firmware then dual sim will work. Thats what i did and im using dual sims right now.
[OnePlus 8T Guides, News, & Discussion] KMHartford:
Simple local update

[OnePlus 8T Guides, News, & Discussion] KMHartford:
You have to fill out OnePlus unlock token request form, submit to OnePlus not T-Mobile, then it takes OnePlus a week or 2 then you will get a email with a link to your unlock.bin file would you use to finally unlock your network unlocked OnePlus 8T plus 5G

It says 6t but works for 8t too
[OnePlus 8T Guides, News, & Discussion] awr128:
My About screen looks way different then OP's what does everyone else screen look like that has converted?
[OnePlus 8T Guides, News, & Discussion] craznazn:
which rom did you convert to?
[OnePlus 8T Guides, News, & Discussion] awr128:
Eu
[OnePlus 8T Guides, News, & Discussion] craznazn:
Strange. Your software version still says 11.0.1.3.KB09CB, which is the Tmo ROM, but I see 2 SIM slots in your notification bar.

Check your dialer, which one do you have?
[OnePlus 8T Guides, News, & Discussion] awr128:
There was no dialer, I had to do the Google dialer
[OnePlus 8T Guides, News, & Discussion] badpanda:
We don't need usb debugging ON in developer settings in order to do this?

Also at the OnePlus site for the serial number of the op8t
[OnePlus 8T Guides, News, & Discussion] craznazn:
As in you had to separately download the Google dialer?

Some questions:

How did you enter fastbootd (from adb or fastboot)?

Did you wipe everything (fastboot -w, or via recovery)?

Did you use the script or manual. If script, what is your OS?

If you used the script, roughly how long did the whole process take?
[OnePlus 8T Guides, News, & Discussion] awr128:
Entered fastbootd from fastboot

I wiped by unlocking the bootloader, then wiped after the flash using recovery

Used the script with windows
[OnePlus 8T Guides, News, & Discussion] craznazn:
I wonder if your boot target slot changed somehow. Assuming the script took around 5 minutes to complete, I would try changing the slot and and wipe again to see. Your screenshot really looks like your booted into stock Tmo but with some things missing and dual SIM
[OnePlus 8T Guides, News, & Discussion] awr128:
Every command had a _b which was odd, how do you change the slot
[OnePlus 8T Guides, News, & Discussion] craznazn:
That's just telling you that it's flashing to the _b slot. Go to fastboot and run

fastboot getvar current-slot

That'll tell you which slot you are booting from.

Since you seem to have flashed everything to _b, try this:

fastboot set_active b

Then wipe everything again, let me know what you see after that
[OnePlus 8T Guides, News, & Discussion] awr128:
Current slot is b
[OnePlus 8T Guides, News, & Discussion] craznazn:
If you still have the output of the script, can you paste parts of it?
[OnePlus 8T Guides, News, & Discussion] awr128:
I'm having to msm back to tmo, I tried flashing to the a slot and it completely bricked
[OnePlus 8T Guides, News, & Discussion] craznazn:
Sounds good, let me know if you have any issues.
[OnePlus 8T Guides, News, & Discussion] awr128:
I've never had so much trouble flashing a device before, I've flashed plenty
[OnePlus 8T Guides, News, & Discussion] Ryano89:
Just keep asking. I called TMobile and got told no, reached out on Twitter and got told no, Facebook messenger them and they unlocked for me. I told them I was a dev and needed sim unlock for my "work" lol
[OnePlus 8T Guides, News, & Discussion] CoolRalph:
I've been doing that for years they're just giving me a hard time this time lol.
[OnePlus 8T Guides, News, & Discussion] barguybrady:
I'm sorry, but this statement is very difficult to understand.
[OnePlus 8T Guides, News, & Discussion] barguybrady:
when did this become a 'thing'?

When I got my 6t, it was un-lockable from Dev Settings right away, and my SIM was always unlocked ?

And ideas when this All Changed ?
[OnePlus 8T Guides, News, & Discussion] craznazn:
All this says is if you convert before sim unlocking, you will not be able to do so until you flash the stock tmobile rom back. You also won't be able to bootloader unlock
[OnePlus 8T Guides, News, & Discussion] barguybrady:
May I then ask your experienced opinion?

16 years as a t-Mo customer - I don't wanna deal with any more b*ll$**4 from them.

Never had to 'ask' for an unlocked boot-loader, or had to 'ask' for my SiM to be un-locked.

This is a new(er) phone, with what seems to be a lot of interest: Do You feel that there may to be more development in Recoveries, and ROMs, and such ?

I can suck-up the re-stock fee ( although it, too, is absolute bull-crap) and go buy off-the-shelf 6t, or 7t, and get Rooted and ad-free without this hassle,

or, do you think I just need to wait until finer minds than mine get involved, and streamline this process ?

I Hate Advertisements.
[OnePlus 8T Guides, News, & Discussion] craznazn:
There's tons of development for this phone. There's also plenty of ways to sim unlock, just search around here in XDA.

Tmobile's stances on sim unlock is pretty much industry standard, maybe slightly better.
[OnePlus 8T Guides, News, & Discussion] Ryano89:
It's only TMobile variants that are locked. It was the same with the 6t if you had the TMobile version
[OnePlus 8T Guides, News, & Discussion] barguybrady:
When I brought my t-Mo 6t home, all that was required was Enable Dev Mode, click "enable OEM unlocking", boot to Fastboot, and as I'm a Linux user, I was ADBing to root, and TWRP, and Magisk, within an hour.

So, my experience was always much easier, with no extra "asking for un-locks" from OP, or from t-Mo.

Hence my confusion.
[OnePlus 8T Guides, News, & Discussion] Ryano89:
I had to convert my TMobile 6t using a converted msm just like the 8t
[OnePlus 8T Guides, News, & Discussion] barguybrady:
You're Right, You're Right, You're Right..!

I had forgotten that step !

Still, I think I will just wait for further "development" on the Mods to get me Rooted.

Like a young Obi-Wan, sometimes I lack patience.
[OnePlus 8T Guides, News, & Discussion] peestandingup:
Can I be on Lineage & use this tool, or do I have to return to T-Mobile stock first? I'm already SIM and BL unlocked.
[OnePlus 8T Guides, News, & Discussion] craznazn:
You can use the tool directly without going back to tmo first
[OnePlus 8T Guides, News, & Discussion] awr128:
Does anyone know if you can root the phone or flash partitions like boot.img without using a computer. I'm pretty sure my data pins on my phone got screwed up some how. No computer recognizes my phone is plugged in to transfer data but the computer will charge the phone. I've tried 3 septate computers and at least 3 different USB C cables. Any suggestions would be greatly appreciated.
[OnePlus 8T Guides, News, & Discussion] craznazn:
you can always try using dd, but you need to be rooted already. The phone should still be under warranty I would think that might be the best bet and just get it replaced.
[OnePlus 8T Guides, News, & Discussion] afdals:
Can I relock the bootloader after converted to Global Rom of my Oneplus 8T?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Yes. You don't even need to unlock the bootloader in the first place.

How to do this for oneplus 8?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Someone with the phone makes a conversion MSM.
[OnePlus 8T Guides, News, & Discussion] chowhell:
Hi, I've been on the phone for an hour today with Sprint trying to port my old number from ATT on a modded international Oneplus 8t+5g. It's super weird because it kept giving me "device is not able to be activated" error on the rep's side. I think having international ROM on tmobile variant is simulating a SKU code or something, because my IMEI definitely shoes my phone can be activated on sprint's network. I see reddit posts complaining that oneplus 8T doesn't work on Sprint, only tmobile...so I'm hoping to reflash original ROM, have Sprint port my old number, and then reflash using your cracked MSM to international...I wonder if I will mess up my connection to Sprint's network when I redo this. Any thoughts?

On a positive note, I'm noticing 31-36° temps vs 40° on tmobiles software, so this upgrade is definitely something I want!
[OnePlus 8T Guides, News, & Discussion] craznazn:
The activation and software you are running shouldn't matter on sprints side at all, just the IMEI must be supported. It's possible that sprint just doesn't support the phone at all. You can always ask to go TNX and get a T-Mobile sim
[OnePlus 8T Guides, News, & Discussion] awr128:
I had TMobile replace my 8T, the best part was, all I needed was to put my existing SIM card into the replacement phone and I was able to SIM unlock it using the TMO unlock app before converting over to the EU ROM.
[OnePlus 8T Guides, News, & Discussion] GenesisDH:
Sprint definitely supports this phone. I have used it as my daily driver since December, with a Sprint UICC and plan. Purchased from a physical store directly.

I completed the conversion to EU using your modded MSMtool and things have worked fine.

Now, I can't do PRL or profile updates, as that isn't on the non-TMO software. For those who are already activated, this doesn't matter (for that poster, initial activation matters so reflashing was a good idea). Most of this stuff is becoming less relevant as TNX is being pushed hard. (Personally I am avoiding TNX until they fix the roaming issues and video throttling on grandfathered plans like mine)

Once you get the device to activate using the factory software, you can convert back to an international software and things should work fine. It may take a while for 5G access to show up but otherwise everything works, including CDMA (another plus: you can turn off VoLTE unlike the factory software).

Did you get this phone second hand? If so, then it is possible it was blacklisted on Sprint for some reason. That might be why the rep couldn't activate it.

[OnePlus 8T Guides, News, & Discussion] craznazn:
I've heard people having success using different cables / usb ports. YMMV, MSM can be finicky
[OnePlus 8T Guides, News, & Discussion] awr128:
Keep trying, it might help to keep holding the volume up and down buttons until you see it communicate and start downloading to the phone.

Hi. I don’t understand, if my phone is locked on tmobile, will it unlock it? Thx)))
[OnePlus 8T Guides, News, & Discussion] craznazn:
It will not SIM unlock
[OnePlus 8T Guides, News, & Discussion] sameog:
No, MSM is only to revert back to tmobile stock. Unlocking your phone is done through tmobile.
[OnePlus 8T Guides, News, & Discussion] GaryJB2017:
I converted my TM 6T with no issue to the Global firmware. I see they are suggesting for the 8t to backup the modem for this phone just incase. So my question is how do you do this? I searched thru this thread and didn't see any discussion on backing up the modem. I expect the conversion will work great even if I don't back them up, but it would be great to know how to do it.

Thanks

Wow really nice work done here @craznazn , was wondering when you might release a version for the OP8 t-mobile version. It sucks seeing the 8t and the 9P already have this method but not the regular 8 :(

I hope that you work on one for the tmo OP8 as I'll be ready to test and report ASAP

I got my hands recently on the firehose .elf file that I extracted it from the .ops fw using a python script made by a guy named "bkerler" , but idk what to do with it.

If you got some ideas laying around I would be thrilled to test them.

Waiting for response, peace out.

Hey there! I'm confused. Does this new approach require sim unlock or will this new approach still require a sim unlock? Thanks.
[OnePlus 8T Guides, News, & Discussion] craznazn:
I don't own an 8, and there are weird problem with that model in particular, so I won't be making one unless I get an 8.

No sim unlock is needed, but you won't be able to sim unlock once you are eligible without the tmo ROM, just using it as a SIM&BL locked EU / Global phone

Hey all. I saw earlier this year that the consensus was that the EU version worked better than the Global version on T-Mobile network and such. Is this still the case?

Just finally got around to doing this because my phone factory reset itself after the stock T-Mobile OTA I got today so I figured... might as well? lol

TL : DR

Is EU still better than Global when using T-Mobile service?
[OnePlus 8T Guides, News, & Discussion] L0ND0NB0Y:
So sad for tmo op8 @craznazn , I really do hope someone figures it out soon. Gimme a PM when you have something to test. My device is useless without a BL unlock 😞
[OnePlus 8T Guides, News, & Discussion] craznazn:
They actually should use the same baseband version. EU is better in the sense that you don't have to contend with Google's OTA server (and having incremental only for a while), allowing you to update faster with Oyxgen Updater. Additionally, EU version should have slightly better privacy controls, because EU. You can always do a full update to Global after conversion

Thanks for the answer. By any chance, do you know how to install the phone's drivers? The MSM tool is unable to read my phone in edl. I looked at the FAQs and found the driver but I am unable to install the cab file. The file is in my downloads but when looking for it to install, it isn't there.
[OnePlus 8T Guides, News, & Discussion] Hey-Hi:
All, I have scoured through many of the comments but am at a complete loss on what the steps are.

Is there more to it than just these 7 steps? If that is it, then what are "Old fastboot method" and within that "manual" and comments about payload dumper etc etc etc.

Thanks in advance for your patience with this noob.
[OnePlus 8T Guides, News, & Discussion] GamingDoggo:
As far as I know it is only those 7 steps. I did this yesterday with only these 7 steps and everything is fine. The old fastboot method is another way to convert it before the msm tool.
[OnePlus 8T Guides, News, & Discussion] Hey-Hi:
ok I'm stuck.

I followed step 4 and pressed "start" but nothing would load. I tried this multiple times and nothing. I went on to step 5 and put my phone in EDL mode by turning it off then holding the volume up and down then I plugged it to my computer and let go . . still nothing even after 5 mins . . .

and now my phone wont turn on...

and after I close the msm tool and try it again, then it says "waiting for device"

Please advice
[OnePlus 8T Guides, News, & Discussion] GamingDoggo:
Hold volume up and power at the same time. I had the same problem. You need the Qualcomm drivers. Alright, download the drivers from here http://download.windowsupdate.com/c..._fba473728483260906ba044af3c063e309e6259d.cab

After that create a new folder and title it drivers or something like that and move your downloaded file to that folder and extract the .cab file. This should create another file. Now, reboot your phone to edl mode and on your computer go to device manager and find the your device phone it should be something like qusb bulk. Now right click on it and click update drivers then search my computer for drivers. From there find your driver file, click it and click the file that was created after the extraction. Then just install them and retry the msm tool.
[OnePlus 8T Guides, News, & Discussion] Hey-Hi:
Holding the volume up and power didn't do anything.

Which one is the ".cab" file? I didn't see it.

I am having an issue where the app (MSM) doesn't do anything after trying the volume keys on the phone. I already have the QUALCOMM driver and my phone shows up correctly in device manager.

My steps:

Install MSM program from thread, and use correct settings:

Starting program, and then holding volume down/up on the powered down phone, then plugging in cable to PC.

Results: After a plugging in the cable, Windows makes the 'device connected' sound. My phone screen is black the entire time. Then, the disconnect sound happens, then a few seconds later, the reconnect sound happens again. My phone is permanently stuck in this "off" mode, where no buttons do anything until I hold volume up + power for 10+ seconds, and that lets it start again.

During all points in this process, the MSM app says "Waiting for device"

Additional things I've tried: restarting phone & pc, trying a different cable & different pc, factory reset of Oneplus 8T, enabling USB debugging and root access in developer options.

I'm lost!! I've tried the volume up/down combo like 20 times now over the past few hours, and so far that's resulted in either 3 conclusions. A black screen that is permanent until I do more combos to exit, a screen with big green text and multiple lines of options, and a standard boot with the T-Mobile logo.

No matter which occur, the MSM program still says "waiting for device"

Does the conversion work with all T-Mobile version OnePlus phones?

I have T-Mobile version N200 (SIM and bootloader unlocked), can I use manual method to flash US unlocked ROM?

[OnePlus 8T Guides, News, & Discussion] jcsww:
Check the forum for the OnePlus N200. Conversions can vary greatly by device model.
[OnePlus 8T Guides, News, & Discussion] mingkee:
Unfortunately, nobody did it due to no MSM for US unlocked version.

However, since T-Mobile MSM is available (mine is T-Mobile version), I may take a risk.

Moreover, I have T-Mobile version 8T sitting around and I would like to convert to US unlocked as well
