Especially when the Open Market 9 isn't even dual SIM (the more expensive 9 Pro is), it doesn't have a lot to improve on from the T-Mobile-branded 8T.
[OnePlus 8T Guides, News, & Discussion] craznazn:
Heh, the pro isn't anymore

https://www.reddit.com/r/oneplus/comments/mcedgk

JerryRigEverything's video clearly shows a single SIM tray like the one we had in our TMO 8T. Once the phone is out you can go to a store with a flashlight and see if the pins are in there, if so you might be able to flash a EU 9/9pro firmware.... but I'm not gonna bother haha.
[OnePlus 8T Guides, News, & Discussion] GenesisDH:
Oh wow, I missed that, but I haven't looked at Reddit today. 😅
[OnePlus 8T Guides, News, & Discussion] craznazn:
Well, @badpanda did make me interested in fixing the about screen, so it's at least partially fixed... instructions in the OP.

How to boot this twrp image?

I am currently on TM 11.0.7.9 version, and in order to convert should I MSM to the TM earlier version than the OP conversion version first?
[OnePlus 8T Guides, News, & Discussion] awr128:
You have to be in regular fastboot

fastboot boot recovery.img

Twrp is still broken so you want get the twrp screen, you will know it's in twrp because your screen will flash every few seconds
[OnePlus 8T Guides, News, & Discussion] craznazn:
If you use TWRP, make sure to remove any screen locks / pin locks first, because you won't be able to input it.

For the conversion, I've never tested it on a 11.0.7.9, I don't see why it would affect the conversion, but you never know... The 8T is finicky sometimes, so please give it a shot and then report back :)
[OnePlus 8T Guides, News, & Discussion] awr128:
I've used it on .7.9 and .7.10 to pull boot images and patch them for root without any issues and I'm pretty sure I had at least a pin code set.
[OnePlus 8T Guides, News, & Discussion] craznazn:
I don't see why you wouldn't be able to flash the tmobile modem, or just ask someone to pull their international/global modem for you and try that. No idea if the EU rom will play nice with it though, you might have higher battery drain or unresponsiveness. Doesn't hurt to try and report back
[OnePlus 8T Guides, News, & Discussion] jwarrior319:

Here we go, someone posted on the other forum the full OTA for global

https://xdaforums.com/oneplus-8t/help/covert-tmo-to-international-t4184369/post83913201

Can anybody confirm if it's indeed the full global OTA or nah?
[OnePlus 8T Guides, News, & Discussion] Anon1136:
It doesn't look similar to the EU rom which includes OTA in the name
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
I noticed that as well, but it's 4.4gb or so, maybe they changed the file name for some reason
[OnePlus 8T Guides, News, & Discussion] craznazn:
That file is the MSM packed image, not helpful for conversion yet.

[OnePlus 8T Guides, News, & Discussion] craznazn:
We've had that file since MSM was released, it's what I'm working on right now.

That other file is the EU rom
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
Got it, thanks, I just got excited when I first saw it so I decided to post it here, I guess I'll be waiting for you to finish up unpacking it and making it useful for conversion

Did you convert using the euro firmware or the global firmware?

Tutorial?
[OnePlus 8T Guides, News, & Discussion] jwarrior319:
Euro with the guide in OP
[OnePlus 8T Guides, News, & Discussion] badpanda:
How?
[OnePlus 8T Guides, News, & Discussion] craznazn:
You are in the thread, it's in the guide.

Also, I updated the guide to make the instructions easier and more concise.

Will TMobile 5G work after this update conversion? Or will it have issues with the TMobile network?

I have a TMobile oneplus 8t from TMobile network wise works great. Worried I will have network issues after conversion.. can anyone share?
[OnePlus 8T Guides, News, & Discussion] KMHartford:
5g works fine, haven't had any issues, waiting patiently for the global rom to be released from OnePlus
[OnePlus 8T Guides, News, & Discussion] badpanda:
After carrier unlocking how do we get the unlock code for oneplus bootloader unlock?
[OnePlus 8T Guides, News, & Discussion] KMHartford:
https://account.oneplus.com/signin/...gn=e6d35ae0ae7117febfd39201dd1f01ed&from=null

Takes 7 to 14 days, took 7 days for mine.
[OnePlus 8T Guides, News, & Discussion] SmileBigNow:
Once the Global ROM is available will we need to go over the entire process again or it's a simple update from Local Update?
[OnePlus 8T Guides, News, & Discussion] badpanda:
But we're do we get the actual unlock code that oneplus is asking from TMobile ?
[OnePlus 8T Guides, News, & Discussion] druguman:
Was not able to boot TWRP, it just went to the pink T-Mobile splash screen and stayed there for a minute then rebooted to the same splash screen. Had to hold the power button for a while to break out from the loop.

Proceed with OP guide, run the flash-all script. When finished initial setup the system update comes up. Should I proceed with the update or follow OP with Oxygen Updater?
[OnePlus 8T Guides, News, & Discussion] awr128:
Either one really
[OnePlus 8T Guides, News, & Discussion] craznazn:
IMO, you should use oxygen updater's full update. If the system updater tries to incremental update, it'll probably fail. Also, this way you get to choose the next version (global, EU, etc)
[OnePlus 8T Guides, News, & Discussion] awr128:
If your bootloader is still unlocked it will force system update to download the full update. If you want to relock your bootloader then I would recommend the full system update through the system update. Like crazazn said if you want to switch to another regions rom then oxygen updater is the way to go.
[OnePlus 8T Guides, News, & Discussion] dcmtnbkr:
If I'm on the latest global beta, can I use the EU 11.0.3.4 conversion package from the OP to convert over to the EU version? Im not worried about having to wipe.
[OnePlus 8T Guides, News, & Discussion] awr128:
Yeah, you should be fine, when you run the flash all script, it rewrites all the .img partitions.
[OnePlus 8T Guides, News, & Discussion] druguman:
If I relock the bootloader will I lose the root?
[OnePlus 8T Guides, News, & Discussion] awr128:
Do NOT relock your bootloader with a modified boot.img (root) you will get a corrupt error and your phone will not boot.
[OnePlus 8T Guides, News, & Discussion] Seraph 2:
I'm considering buying a Global Unlocked phone (better prince then through T-Mobile whom I have service). As I understand it, the WIFI calling will not work on this phone because its Global. I have no cell reception at home and use WIFI calling on my current phone. Can i use this same process to convert the Global phone over to T-Mobile so i can use WIFI calling feature with the full T-Mobile rom?

It seems from the OP "NR and LTE bands are flashed in nvRAM, not in modem.img or any other partition. You cannot get global bands by flashing a global ROM, nor can you lose TMO bands by flashing another ROM." this may not be possible. Is this where the WIFI calling feature is baked in?

Please advise.... Thank you for your time...
[OnePlus 8T Guides, News, & Discussion] jcsww:
WiFi Calling on the Global firmware works perfectly fine on T-Mobile.
[OnePlus 8T Guides, News, & Discussion] dcmtnbkr:
I'm running the EU firmware on my tmobile branded phone and I have voice over WiFi. Not sure if this gives you the info you need or not though.
[OnePlus 8T Guides, News, & Discussion] Seraph 2:
Thank you my friend. I've read so many threads and it "appears" the feature is there, and should work, but does not work on AT&T nor Verizon and can't deny nor confirm with T-Mobile. Apparently the feature only works on official branded factory T-Mobile phones. So i thought i would have to flash a full OTA T-Mobile rom to get it to officially work. Thank you for confirmation.
[OnePlus 8T Guides, News, & Discussion] craznazn:
Wifi calling will be fine, the only thing you might not get is USC roaming since their roaming agreement requires the IMEI to be in the database, but I think even global should be fine for that.
[OnePlus 8T Guides, News, & Discussion] jcsww:
T-Mobile USA uses the default implementation of WiFi Calling that Google pioneered. This is what the OnePlus global North America firmware also have implemented. T-Mobile does not require a device be purchased directly from them in order to use their carrier features, unlike AT&T and in some cases, Verizon as well.
[OnePlus 8T Guides, News, & Discussion] Seraph 2:
understood, thank you. My other apprehension was i know on my current phone, if i wanted to flash an alternative rom, Lineage, etc, non of them have the Wifi calling feature working. So i really thought i needed to use a full OTA Tmobile rom to convert it over. Good to know. Thanks again.
[OnePlus 8T Guides, News, & Discussion] mslezak:
Will it boot relocked on Global with the stock boot.img (no root) and function like a factory NA variant? Anyone try?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Yes, you can relock it and it will behave like a normal global 8T, except the about page will still be broken. Nothing you can do about that since the rom reads the prop in order to populate it, and the model name (kebabt) is different than global (kebab).

If you want to lock it, I would run the full ota via local upgrade first and then don't touch any of the partitions. People have done it in this thread before.
[OnePlus 8T Guides, News, & Discussion] dcmtnbkr:
I'm relocked on the EU firmware and working fine. Relocked so that I could use netflix.
[OnePlus 8T Guides, News, & Discussion] mslezak:
Thanks, so you'd have to extract the super partition, change the buildprop to kebab, then rebuild it in order to populate the about phone page. But then it wouldn't be signed by OnePlus anymore so that's a no go.
[OnePlus 8T Guides, News, & Discussion] craznazn:
Exactly, but it's just the about phone page / cosmetic and if that doesn't bother you, relock away
[OnePlus 8T Guides, News, & Discussion] Unbornlegend123:
Please dont roast me for this I feel like this a stupid question but want to ask anyways. I saw there is an Open beta for test builds ( no Full upgrade for me to take as of right now). Is this now technically a global one plus 8t or still a tmobile one? Beta not available for tmobile and says dont even try flashing, Since I did the conversion can I flash it now or just wait for a new update to come out then do the full update that way. and just noticed even after letting the phone settle unlocking the phone is painfully slow. takes at least 5 seconds for the screen to light up after pressing the power button/
[OnePlus 8T Guides, News, & Discussion] studio1c:
I will be doing this to my oneplus 8t that I just got. Im waiting for the bootloader token I will then be converting to NA aka global. my phone is at the newest TM system.

Yes the method that is used for this is nothing hard I also have a 6T that is flashed for int and dual sim use.

Thanks for the info and I shall report what I get done :)

goal is to NA + ROOT :)
[OnePlus 8T Guides, News, & Discussion] jcsww:
That made me think... Would it be possible to convert from the T-Mobile to the Global or EU, root, edit the prop to the model name of the firmware now on the device, then unroot, and lock the bootloader and have that screen populate properly?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Nope, you would modify /system and not pass cryptographic checks, in addition to failing safetynet. If you tried to lock the bootloader, it'll softbrick on boot and you still need to msm.
[OnePlus 8T Guides, News, & Discussion] craznazn:
I really recommend going EU btw, unless you plan on locking the bootloader after conversion. Full ota had been an issue to find in the past due to the usage of Google update servers, and eu rom is working great.
[OnePlus 8T Guides, News, & Discussion] dcmtnbkr:
Why would locking be an issue on EU? I've relocked mine, did I do something I shouldn't have?
[OnePlus 8T Guides, News, & Discussion] craznazn:
I'm saying if you go the Global route, you need to relock your bootloader in order to get incremental OTAs. Otherwise, you'll have to wait until full OTAs are available in order to update, which could be months behind (as we've seen in the past).

If you go the EU route, the full OTA has always been available as soon as it's released, and you won't have any issues updating right away.

Since you relocked your bootloader, it doesn't matter which route you go. If you plan on having unlocked bootloader, I recommend EU.
[OnePlus 8T Guides, News, & Discussion] amandeepsaini11:
Can i convert IN version to EU?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Just local upgrade the eu full ota. You can use oxygen updater and just set your device to 8T (EU)
[OnePlus 8T Guides, News, & Discussion] studio1c:
Ok. So this morning I got my unlock token and unlocked the bootloader. I then flashed the phone with the files on the thread and now the phone is converted to global.

I don't plan on re locking the bootloader so that's not a problem. I guess I will flash the EU edition and then root and all. Thank you for the reply
[OnePlus 8T Guides, News, & Discussion] studio1c:
Well i just got home from work and i did it all. I went to oxygen updater and switched to EU , then downloaded the zip. I moved it to my pc unzipped it and then ran the payloader dumper to get the boot.img file for rooting.

I flashed the phone with local upgrade and it did it no problem took about 10 mins.

It rebooted it was still setup with all my current info. I then tested the root and it worked i pushed the magisk_patched.img and then did the next steps everything worked like it should.

So i then rebooted to recovery and re wipped the phone and now setting it up again.

Phone booted I set my user up and then i booted the magisk image then did direct install :)

everything is up and running i have TB will all my apps now on my brand new 8T thanks for all the info
[OnePlus 8T Guides, News, & Discussion] craznazn:
Glad everything is working out. I had bad experience with tb on newer devices, if tb is giving you trouble I recommend looking at swift backup

I extracted the Payload and included the flash_all.bat here for the Global Op8T ROM that was released yesterday. It's in .7z format so you need 7zip or similar to extract.

[OnePlus 8T Guides, News, & Discussion] kanpol:
do i put the folder in the adb folder or do i copy all the contents from the convert folder and paste it into adb folder

this is the part im stuck at ,not sure what cwd. stands for

Execute "flash_all.bat" for Windows, or "flash_all.sh" for Linux, from the unzipped directory from step 2 as cwd.

Nevermind figured it out

I got a quick question, after I converted my TMO to GLO, i upgraded to oxygen os 11.0.6.7.KB05AA but now i need to downgrade to 11.0.5.6 . What would be the best way to go about it, thx
[OnePlus 8T Guides, News, & Discussion] craznazn:
Do you have the full OTA for 11.0.5.6? If so, try the following with root:

resetprop ro.build.date.utc 1400000000

Then apply the OTA from local upgrade as normal
[OnePlus 8T Guides, News, & Discussion] kanpol:
thx but not sure how to do that and i dont have the ota, still looking for it. can I run the convert file again, I dont mind if i have to set it up again

I just downloaded the ota and im rooted but not sure how to do what you said, could you explain it a little more, thx
[OnePlus 8T Guides, News, & Discussion] craznazn:
run in your terminal:

adb shell su -c resetprop ro.build.date.utc 1400000000

edit: simplified to 1 line
[OnePlus 8T Guides, News, & Discussion] kanpol:
i put my phone in fastboot and run that
[OnePlus 8T Guides, News, & Discussion] craznazn:
no, boot your phone normally.
[OnePlus 8T Guides, News, & Discussion] kanpol:
sorry kinda lost, my bad
[OnePlus 8T Guides, News, & Discussion] kanpol:
can i use msm tool and then ill just reunlock my boot loader
[OnePlus 8T Guides, News, & Discussion] kidownzus:
whats the answer to your original question. lol am at this point rn
[OnePlus 8T Guides, News, & Discussion] kanpol:
just put the whole folder in your adb folder and run flash_all bat if youre using windows
[OnePlus 8T Guides, News, & Discussion] kanpol:
do i use terminal emulator or do you mean windows cmd
[OnePlus 8T Guides, News, & Discussion] craznazn:
if you want to use terminal emulator, just ignore the adb shell part. otherwise, use cmd
[OnePlus 8T Guides, News, & Discussion] kanpol:
ok i can do the cmd part, the part im confused with is do i need to put the ota in the adb folder, is phone in fastboot or is it just turned on like normal, sorry about all the questions
