i will say that if you are persistent you can get somebody at tmobile to unlock it. it took me nearly 10 times at various times of the day on the tmobile twitter help chat and finally got somebody that asked me for the imei and just unlocked it for me.
[OnePlus 8T Guides, News, & Discussion] umairkhalid415:
Sir do

Sir can you guide why on oneplus 8 tmobile variant dual sim doesn't work even after converting it to global variant even I have changed imei on second slot it detects sim but no signal.
[OnePlus 8T Guides, News, & Discussion] christian.farmerf:
Hey, I responded to your comment a while ago. I found a different fix that allows bootloader unlock without a sim unlock. There is a tool that can ungrey OEM unlocking option. Go into system options, run the tool, open developer options, and enable OEM unlocking.

[OnePlus 8T Guides, News, & Discussion] Rootk1t:
You can do it via "adb shell pm uninstall --user 0 com.qualcomm.qti.uim" command.

No 3rd party tools needed.
[OnePlus 8T Guides, News, & Discussion] christian.farmerf:
Yeah I know. The tool does exactly that but has a couple other useful gadgets installed. Any idea if I could use this to unlock my Verizon pixel 2xl?
[OnePlus 8T Guides, News, & Discussion] craznazn:
No, you are generally fk'd because you got a verizon device. There was an exploit for a verizon pixel (could've been for the 2), but it's not just an adb command.
[OnePlus 8T Guides, News, & Discussion] christian.farmerf:
Yeah, I would assume. I'm not really even looking to root it or anything because it's so old at this point. I've moved on to my OnePlus 6t, 8t, and 9 for my android modding.
[OnePlus 8T Guides, News, & Discussion] osmingab85:
Excuse my ignorance... but, this is the best process to make the 8t T-mobile a global version right...?? It's just that I don't want to be left without a phone since I'm not an expert in this...! 🤣🤣 Thank you
[OnePlus 8T Guides, News, & Discussion] jcsww:
It is. The instructions to convert to EU are in the OP. Once you are on the EU firmware, which is what I am personally using on T-Mobile USA. You can use a full image to update to the NA/Global, if you wish, through the Local Update option under System Updates.

You will more than likely want to have your device permanently SIM Unlocked before flashing though. You can only SIM Unlock the T-Mobile device using the T-Mobile firmware.
[OnePlus 8T Guides, News, & Discussion] osmingab85:
Thank you very, very much... for taking the time to answer me... I will do the process at night because I would really like to have more options to make the most of this beauty...
[OnePlus 8T Guides, News, & Discussion] jcsww:
If your device isn't SIM Unlocked. Reach out to the T-Force via Facebook or Twitter to request the permanent unlock. You must be a T-Mobile customer though and no past due balance owing. There was a thread around somewhere for SIM Unlocking for T-Mobile as well, but I am not sure if that person is still doing SIM Unlocks for T-Mobile devices.
[OnePlus 8T Guides, News, & Discussion] osmingab85:
It's from the T-mobile company, but I have it with another operator... I imagine it's unlocked... because I can put any Sim on it... I imagine it's fine now to do the steps in the post.
[OnePlus 8T Guides, News, & Discussion] jcsww:
Yep. Sounds like you are all set to follow the OP to flash.
[OnePlus 8T Guides, News, & Discussion] osmingab85:
Brother..!! one more query... if I make this change... will I be able to install color Os on this phone...?? or will I only be able to install the oxygen versions os...?
[OnePlus 8T Guides, News, & Discussion] jcsww:
ColorOS is for the Chinese version only. It can be installed though, but you will lose Google Services unless you are comfortable sideloading them. The OxygenOS version of Android 12 is still in beta. Personally, I would wait for the official release because all versions of Android 12 on many different devices, across different manufacturers, including Pixel's, have some serious issues.
[OnePlus 8T Guides, News, & Discussion] osmingab85:
Este archivo que se va a descargar se detecta como un virus..?? ¿Es ese hermano normal?

Brother, good evening try to do the process as it says there; but you don't see any progress on the screen of the program... I have to wait for some progress on the screen of the program or does nothing more than turn on the phone ...? help
[OnePlus 8T Guides, News, & Discussion] jcsww:
The device has to be in EDL Mode to convert with the MSM Tool. The correct drivers for the device while in that mode also have to be installed.
[OnePlus 8T Guides, News, & Discussion] osmingab85:
I've already installed the drivers... the problem it gives me when trying to do the process is connectivity due to a DDR failure... I haven't been able to go from there...!! The program does not recognize it...
[OnePlus 8T Guides, News, & Discussion] jcsww:
I haven't personally seen that error myself. From my understanding though, some devices have DDR4 and some have DDR5. There should be a post or few in this thread about it. That's a guess. Do you have USB Debugging enabled in Developer Options?
[OnePlus 8T Guides, News, & Discussion] osmingab85:
Yes brother... I saw in the comments other users with the same problem... But, I didn't see that they had a solution...!! I will continue reviewing one by one to clear up any doubts... thanks for your time brother

That is the model of my phone..
[OnePlus 8T Guides, News, & Discussion] steep nose:
Will this work with the tmobile 8 model IN2015?

I have not been able to get any help from either t mobile or oneplus.

When I try and apply for the token using adb / fastboot I just get error messages.

I updated to the latest drivers and tried it on both windows and Ubuntu.

I would like to bypass the token and never talk to Tmobile or Oneplus ever again.

My sim is unlocked because I bought my phone from OnePlus.
[OnePlus 8T Guides, News, & Discussion] jcsww:
Did you enable OEM Unlocking in Developer Options?
[OnePlus 8T Guides, News, & Discussion] steep nose:
yes and it still asks for the unlock token when i fastboot oem unlock.
[OnePlus 8T Guides, News, & Discussion] jcsww:
Did you flash the token? I don't remember the command, but it should have came with the support e-mail from OnePlus with the token for your device.
[OnePlus 8T Guides, News, & Discussion] craznazn:
This will not work with OP8. Most likely your error is due to out of date fastboot/platform tools.
[OnePlus 8T Guides, News, & Discussion] Ejvyas:
You are right. I had the same problem and never found a solution.

Someone asked me to manually choose the ddr. I never tried it. I think global or Indian version MSM have that option.
[OnePlus 8T Guides, News, & Discussion] thattechguy_69:
yo man you are awesome on this convert! can you please help out our community? we are in need of an msm tool to convert op8 to EU/Global and we don't have one. you can atleast teach me how to make one. i appreciate any help thank you!
[OnePlus 8T Guides, News, & Discussion] craznazn:
Unfortunately the OP8 has a different MSM process that doesn't work the same way. I also don't have a TMO OP8, so I can't debug it. Sorry
[OnePlus 8T Guides, News, & Discussion] thattechguy_69:
F thank you for the reply. appreciate what your doing for the community
[OnePlus 8T Guides, News, & Discussion] badpanda:
This is not the easy but is definitely a progress ?
[OnePlus 8T Guides, News, & Discussion] sameog:
Guys,

I just downloaded this. It's the global build with msm. Thoughts?
[OnePlus 8T Guides, News, & Discussion] awr128:
Finally it to flash correctly, I ditched the downloaded flash batch script that's in the first thread and created my own and that seemed to do the trick.
[OnePlus 8T Guides, News, & Discussion] craznazn:
Can you share what went wrong with the script in the OP? I can either modify it or if you want to share, use yours
[OnePlus 8T Guides, News, & Discussion] sameog:
how did you extract the payload? I downloaded and installed python and received an error message. See below:

PS C:\Users\gateway A6\Downloads\payload_dumper\payload_dumper> python -m install pip protobuf

python : The term 'python' is not recognized as the name of a cmdlet, function, script file, or operable program.

Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

At line:1 char:1

+ python -m install pip protobuf

+ ~~~~~~

+ CategoryInfo : ObjectNotFound: (python:String) [], CommandNotFoundException

+ FullyQualifiedErrorId : CommandNotFoundException

Before I do something stupid, can you walk me through? I don't know python. I hear I can "make" a fastboot room once the payload is extracted.
[OnePlus 8T Guides, News, & Discussion] awr128:
I'm not sure what went wrong exactly, I did have a few files that failed to flash over. I just took the main flash commands and made them into a batch file.
[OnePlus 8T Guides, News, & Discussion] craznazn:
You're on windows, download the windows extractor...
[OnePlus 8T Guides, News, & Discussion] sameog:
I just noticed it was a ZIP file. :silly:

BTW, when I get the payload extracted, is there a way to fastboot everything into my phone? I have a batch file from the oneplus 8 global build fastboot rom build I used.

Let me know please and thank you!
[OnePlus 8T Guides, News, & Discussion] craznazn:
Strange... maybe it's something to do with the linefeed, nothing looks off in the syntax. Can you share your file anyways in case I missed something obvious?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Just follow the instructions in the OP carefully. Then if there are issues post it. Dont use scripts from other devices.
[OnePlus 8T Guides, News, & Discussion] awr128:
Sure, what's the best way to post it
[OnePlus 8T Guides, News, & Discussion] craznazn:
Here, wrap it around

blocks, or pastebin, or anywhere really :D
[OnePlus 8T Guides, News, & Discussion] craznazn:
Well, I don't see anything different... Hopefully it was just a fluke
[OnePlus 8T Guides, News, & Discussion] awr128:
Just straight flash commands, the other one has the echo messages
[OnePlus 8T Guides, News, & Discussion] Thanat0s24:
I have followed these directions to a T, and every thing went according to plan, except of course the actual conversion to the EU version, after wiping all data and rebooting it still is the same TMO version. I know I am missing something here, probably something simple, anyone have any ideas?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Looks like you have the same issue as awr128. Seems like the windows script still needs work. Look above and create your own .bat file for flashing, I'll modify the OP to point to that post.
[OnePlus 8T Guides, News, & Discussion] Thanat0s24:
Actually, scratch that. I just ran it again and noticed when I run the script, it says FAILED, no such directory on every line. any idea what I am doing wrong?
[OnePlus 8T Guides, News, & Discussion] craznazn:
Are you running it in the payload output directory? If you are in Windows, it'll be payload_dumper-win64\payload_output. Put the script in there and try running it.
[OnePlus 8T Guides, News, & Discussion] Thanat0s24:
Yeah, I did put it in that directory. I just made my own bat file, and it came up saying target reported download blah blah. this is annoying me, I feel like a fool haha.
[OnePlus 8T Guides, News, & Discussion] cabagekiller:

Sadly I can find the original error I was receiving but I have not found a solution to my current "param preload failed" error I am receiving.
[OnePlus 8T Guides, News, & Discussion] Achi Shukuteki:
You might have to download the drivers. The other thread I linked has a link for it. I just can't get it to work. Maybe it's because I have a T-Mo or I'm using a wrong file.
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
Yes I fixed that issue as well relating to the drivers. I may need to downgrade the firmware maybe? Have you gotten it to work?
[OnePlus 8T Guides, News, & Discussion] Achi Shukuteki:
No. I'm getting a DDR5 error. I may have to downgrade as well.
[OnePlus 8T Guides, News, & Discussion] Achi Shukuteki:
This guy used the Win7.exe
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
Thank you. I got a step farther now its stuck at "Automatic detection of DDR failed" lol but it did go further
[OnePlus 8T Guides, News, & Discussion] Achi Shukuteki:
I'm gonna try the win7 method and see how that goes, in a few.
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
yeah I tried that and got to "automatic detect of DDR failed" :(
[OnePlus 8T Guides, News, & Discussion] Achi Shukuteki:
I have yet to find out what's the fix. In that video, the YouTuber holds on to the volume buttons a bit longer once it's connected. Maybe that's it?
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
I'm using adb to reboot into edl so maybe?
[OnePlus 8T Guides, News, & Discussion] Ejvyas:
see my reply on the previous page. Let me know if that works for you
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
How do you manually choose the ddr?
[OnePlus 8T Guides, News, & Discussion] Achi Shukuteki:
There should be a toggle at the top above the target button.

I tried this and got the same error.
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
Odd. I do not have the target button.
[OnePlus 8T Guides, News, & Discussion] Achi Shukuteki:
It should be to the left of the start button.
[OnePlus 8T Guides, News, & Discussion] Ejvyas:
It depends on the MSM version. You probably have to use a recent EU MSM
[OnePlus 8T Guides, News, & Discussion] Mateensiddz:
bro i did everything but about phone error i want to fix it without root can it possible
[OnePlus 8T Guides, News, & Discussion] craznazn:
You don't, about phone isn't gonna work because the global rom doesn't know what kebabt is and there's no way to spoof kebab without root
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
I see on one of the msmtools I have it but not the TMobile to international msmtools but I still get the same error code. :( May just have to wait for the TMobile unlock code.
[OnePlus 8T Guides, News, & Discussion] Ejvyas:
Tmobile unlock code wont fix that. I am stuck with the same issue. I guess the only option for us is to install Custom ROMs.

I am not sure why others do not face this issue. Maybe its due to recent hardware.
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
I'm just doing this to unlock the bootloader. In adb and fastboot the phone reads on my computer. Just in edl mode with the msmtools is there issues.
[OnePlus 8T Guides, News, & Discussion] Ejvyas:
Let me know what you figure out. At this point I'm stuck but unlocked bootloader
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
With an unlocked bootloader you should be able to fastboot flash TWRP recovery and do what you want.
[OnePlus 8T Guides, News, & Discussion] Ejvyas:
All that is true in the best case. Isn't it?

In normal case, If something goes wrong or phone is bricked we don't have backup option as MSM doesn't work for us. I mean we cannot clean and restore to original. Right?
[OnePlus 8T Guides, News, & Discussion] jcsww:
There might be a stock fastboot ROM. If not, try something close to stock just to get it working. Then you can always try the MSM Tool again, if you wish.
[OnePlus 8T Guides, News, & Discussion] cabagekiller:
sadly the fastboot option will not allow me to proceed due to needing the bootloader unlocked. I may bust out my surface and try the msmtool on it
[OnePlus 8T Guides, News, & Discussion] kenbrownstone:
I'm on a rom now .Can I use this to get to back to OS? My phone is tmo but used international .I'm unlock boot and sim ..Just wanting to try OS12.

its not working , i tried several times. it shows error within minutes of starting to flash. I have network unlocked and bootloader unlocked as well.
[OnePlus 8T Guides, News, & Discussion] Ejvyas:
What error?
[OnePlus 8T Guides, News, & Discussion] samjoandco:
Getting Sahara communication failed error. Tried from 3 different pcs for a week. Tried Windows 8 compatibility mode. It fails exactly at 15-18s.
[OnePlus 8T Guides, News, & Discussion] IanJSaul:
Uh oh...

My 8T is permanently stuck on "Upgrade download failed" - this is due to a bad download on the MSM tool listed in the first post.

I didn't check it initially, and it came down with the wrong MD5 checksum in Firfox 3 times. Tried Chrome, and got a good copy of it finally.

However, I can't seem to get the phone back into EDL mode - I can OCCASIONALLY get it to the REBOOT/RECOVERY/START/POWER OFF/BARCODE/START menu - but it goes right back into a loop to this error screen.

Any guidance on how to recover and reflash at this point? The phone is SIM and "TMobile Unlocked", but not unlocked via the code from OnePlus.

Video of current scenario:
[OnePlus 8T Guides, News, & Discussion] craznazn:
Are you sure you're not getting to EDL? It's pretty much impossible to be able to get to any type of boot without being able to get to EDL. Do you have adb abilities while in recovery mode?
[OnePlus 8T Guides, News, & Discussion] IanJSaul:
I gave it another shot (after being ready to hulk out on both the phone and the laptop) - and shazam - it fired up and took the flash back to stock TMO firmware, and then a flash to the EU.

Thanks for recommending I hang tight and try it again! Cheers, -Ian
[OnePlus 8T Guides, News, & Discussion] Soundtallica:
So I talked to a T-mobile rep on Twitter about sim unlocking their phones, and they say that the unlocking policy has slightly changed in that once your device becomes eligible to be unlocked it will be unlocked automatically. The same conditions to be eligible to sim unlock still apply. In this case, does this mean that if I run this tool on my phone without sim unlocking first, that the phone will still sim unlock automatically once I pay off my phone?
[OnePlus 8T Guides, News, & Discussion] GenesisDH:
Not necessarily, as T-Mobile uses an app unlock method to automate the process, rather than using a punched in code like it used to be done with non-iPhones. The non-T-Mobile OOS software doesn't have this app preinstalled and to my understanding can't be added post-conversion with a successful outcome. You would likey have to swap back to the T-Mobile software using MSM to complete the unlock later, requiring another device wipe.

If unlocking is something you are planning as a goal, I would suggest waiting until the device is eligible to unlock and then converting.
[OnePlus 8T Guides, News, & Discussion] Soundtallica:
Good to know, thank you. I'll sim unlock my phone before flashing anything then.

ANother note is that if you're getting a phone from T-Mobile on a promotional discount where you receive a monthly credit over 24 months, you won't be forfeiting those credits if you pay off the phone early. So that's good news if you're impatient to sim unlock your phone
[OnePlus 8T Guides, News, & Discussion] ITMASTER:
So if I am getting right with this MSM tool method after I convert 8T T-Mobile to EU than I can do local upgrade to 8T global right? Also is there any upgraded MSM tool method yet?
[OnePlus 8T Guides, News, & Discussion] jcsww:
You can. It is recommended that you use a full update image though instead of just the update package. The full update image will help make it more of a full conversion.
[OnePlus 8T Guides, News, & Discussion] ITMASTER:
By saying full update image you mean the ones that can be downloaded from oneplus website right?
[OnePlus 8T Guides, News, & Discussion] jcsww:
Yeah. It's about 4GB.
[OnePlus 8T Guides, News, & Discussion] ITMASTER:
Thanks for reply, I have a question maybe you will have the answer, what you think if I buy from Oneplus website T-Mobile version and export to my country can I unlock this phone is never used in T-Mobile network?
[OnePlus 8T Guides, News, & Discussion] jcsww:
T-Mobile's SIM unlock requirements are not friendly to situations like that. They require the device to be used on the network and the device needs to.be connected to the T-Mobile network for at least 4 full days before an unlock can even be processed.

Thank for that I am moving out to get CN version and convert to global easily . I think the worst scenario to have OnePlus phone it is bye T-Mobile version )
[OnePlus 8T Guides, News, & Discussion] ITMASTER:
There is seller on ebay who says phones are sealed never opened to be used in T-mobile network and they says we can use this guide to unlock once receive phone:

· Connect you phone to WIFI

· Go to Settings

· Go to WIFI & Network

· Go to SIM & Network Setting

· Go to Network Unlock.

· Click and then go to Permanent Unlock.

· It will take some time and will give you confirmation message.

· Sometimes Unlocking Server is Busy or there is some connection problem, then try again.

· It will give you confirmation message once Unlocking is done.

· Restart the devise

I am wondering if we can do the same buying directly from Oneplus US store ?
[OnePlus 8T Guides, News, & Discussion] jcsww:
Personally, I wouldn't believe that. T-Mobile has conditions, just like most other providers, for their devices to meet permanent unlock eligibility. A device that has not been connected to the T-Mobile network for at least 4 full days can't even be unlocked.

[OnePlus 8T Guides, News, & Discussion] jamescable:
So, if I buy the T-Mobile version on a payment plan, obviously not sim unlocked, I can use this to bypass unlock bootloader so I can install custom ROMs and must use T-Mobile sim?
[OnePlus 8T Guides, News, & Discussion] jcsww:
Flashing does not remove the SIM lock or alter the SIM lock state at all. It is highly recommended that you get the SIM locked removed first, because you can only SIM unlock the device on the T-Mobile firmware.
