QAM. https://en.m.wikipedia.org/wiki/Quadrature_amplitude_modulation

It allows for a higher data rate based on the number of streams in a signal. Signals can have multiple streams of streams as well, QAM16, QAM64, etc.

MIMO

The ability to use multiple antennas to host multiple connections. Multi Input Multi Output. Your phone can have multiple physical antennas to send and receive such as 2x2 would be 2 in and 2 out.

Then there's CA or carrier aggregation. The ability to use multiple frequency bands at the same time to boost data thruput. These are expressed as 2CA or 3CA for 2 bands and 3 bands.

I'm not on the latest international version, down 1 version and I have MIMO and QAM signalling.

Hope that helps you. I'll read back to what you were having a problem with.
[OnePlus 7T Guides, News, & Discussion] Josh McGrath:
Thank you for the clarification! It was both of those that Tmo has posted on the help page saying that you will lose I think it was QAM but this could just be TMobile talking to try and stop people from converting maybe.

I'll search for the page and if I can find it, I'll repost it here
[OnePlus 7T Guides, News, & Discussion] awr128:
How do you test for that?
[OnePlus 7T Guides, News, & Discussion] amcferrin90:
If you're rooted, go to the play store and install the "Network Signal Guru". It is a pretty powerful app that provides a lot of behind the scenes data about your cell connection. Just running it won't harm anything. It does provide you the ability to control access to specific frequency bands which can affect your actual service.

What are the steps to preserve root through each update?

EDIT:

It doesn't seem to be working for me. It's just wiping my data, then failing to write some things, then rebooting into what appears to be the T-Mobile firmware still. Pink T-Mobile boot splash and everything. Still build number 10.0.6.HD63CB. And it appears my wireless services seem to be broken. WiFi won't turn on, and mobile data/voice are not accessible. Guess I'll have to start from scratch with the T-Mo 10.0.5 MSM tool and just update via OTA (without root this time, of course, seeing as how I was on an old T-Mo build and incremental OTAs don't work) and convert from there.
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
This MSMTool worked for me, in case anyone else needs it.

Got an update for 10.0.7, gonna try this again. Gotta find my unlock_code.bin file first, though.
[OnePlus 7T Guides, News, & Discussion] nolimit78:
Did you run into any problems following the steps in the OP? If so, what problems did you encounter? What you described seemed like a bad flash. I was able to replicate these steps on a fresh phone that was purchased from Tmobile to verify these steps. Let us know, we can help.
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
I was rooted, on T-Mo 10.0.6, and it just failed to flash a lot of files. I ended up restarting, updating to 10.0.7, then flashing the global firmware again. Everything works now. I'm currently working on rooting it now. Had to reboot from the patched 10.0.9 image (since I had used the latest global ROM) once, install Magisk Manager latest canary, which didn't show any update message, so I rebooted the patched image again, then this time I was able to update. Rebooted, and I have root, AND I pass SafetyNet.
[OnePlus 7T Guides, News, & Discussion] nolimit78:
Sweet!

Now that I'm piecing it together.. I'm wondering if the requirement to flash to the Indian ROM is what installed fastbootd and that's what allowed the global to flash properly.. I wouldn't take that to the bank but it's now a hunch and I haven't validated this at all!
[OnePlus 7T Guides, News, & Discussion] amcferrin90:
I practically did the same thing except I was on global 10.0.8. Somthing's goofed in the patched boot image posted for 10.0.9. I happened to have my phone bugging me to update so I let my device to full update. Then I was finally on stock unrooted 10.0.9, I didn't lose any data and was pretty happy. From there I went to perform root section from OP using the patched 10.0.9 image from another post. This time I just booted the image to see if it was wonky and it was. So I downloaded the OOS 10.0.9 global full firmware, opened the zip file, copied the boot.img file to my device. While on stock with Magisk installed, I patched that boot image with Magisk. Then rebooted, temp booted that image and all was well. Then did a permanent flash of my modded boot.img and are golden.

Anyone who wants my patched global OOS 10.0.9 boot image I'll be glad to share it.

Hi I successfully converted my oneplus 7t from T-Mobile to global firmware but I'm having a issue I'm not very experienced as others doing this I'm trying to get rid of some system apps I don't want I'm using mixplorer with root access but each time I try to delete the app from the system app folder it says no item deleted can someone please help.
[OnePlus 7T Guides, News, & Discussion] Iceman248:
How is it exactly that you flash the global ROM but keep the T-Mobile connectivity at its finest?
[OnePlus 7T Guides, News, & Discussion] awr128:
Modify the flash all script with a text editor by removing the commands to flash the radio files.

The flash-all.bat file is just a text file with a list of commands.

---------- Post added at 10:07 PM ---------- Previous post was at 09:58 PM ----------

We should be able to flash just the T-Mobile radio files instead of the whole ROM, I I'll try it tonight and post my findings.

I've been looking for the stock Tmo modem files but seems nobody has them and I don't have the time to pull them myself, unfortunately.
[OnePlus 7T Guides, News, & Discussion] ziddey:
I dumped my partitions before flashing. And I think there's a tmo edl package here: https://xdaforums.com/oneplus-7t/how-to/op7t-t-mobile-unbrick-tool-to-restore-t4004005

you don't gain/lose bands by flashing modems.

https://drive.google.com/open?id=1prru-OLkEKCuIrOSOBz-jQd8beiSrtX1

i think that's from tmo 10.0.6 maybe?
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
Well, I didn't actually even touch the Indian ROM in either attempt.

The one I used (from a different thread) worked, I just had to boot it twice to get Magisk to give the option to update. But I suppose yours would probably be a safer bet.
[OnePlus 7T Guides, News, & Discussion] noxarcana:
I tried converting to Global while keeping the TMO modem and it did not work. I mean, it kept the TMO modem image, but it wouldn't recognize my SIM card at all. I flashed the global modem image and everything was fine.
[OnePlus 7T Guides, News, & Discussion] Jeroen1000:
Looks like I am stalking you, but I'm not:). That is exactly what I wanted to try too. However, my question still is: if you are on the global rom, do you still have LTE-bands 46, 48 and 71?

If I buy a HD1907 and use this guide, will I be able to use this on Visible/Verizon as if I had bought the 1905?

[OnePlus 7T Guides, News, & Discussion] agentbob123:
Is Magisk Canary required for root, or will the stable version of Magisk also work?

Also, after reading through the 24 pages of this thread, I noticed a couple suggestions to create image dumps prior to doing this work in the event something goes wrong, so you have the ability to restore from your backup. It might be worth adding instructions for creating these image dumps, as well as perhaps instructions for restoring from the dumps should that be necessary.

Thanks for the research and time that's gone into this!
[OnePlus 7T Guides, News, & Discussion] ziddey:
don't need canary

https://xdaforums.com/showpost.php?p=81834565&postcount=129

you can dump the super partition as is or pull /dev/block/mapper instead for individual images you can flash with fastbootd.
[OnePlus 7T Guides, News, & Discussion] carnivalrejectq:
Does it not work after a certain update?
[OnePlus 7T Guides, News, & Discussion] agentbob123:
I think I read somewhere that the procedures used to set this to global don't require any exploits that would be lost with updates. Also, the first post in this thread has been updated: "The idea of this thread is going from 100% T-Mobile Stock 10.0.8 to Rooted Global Firmware. " The newest T-Mobile update is 10.0.8 at this time, so if you go ahead and update, you'll still be able to get to Global. The update includes updated instructions that no longer refer to the need to first flash to the Indian ROM (the old instructions have been moved to post #4 I think, or somewhere in that vicinity).
[OnePlus 7T Guides, News, & Discussion] carnivalrejectq:
Ah I see. I might just get one now. The unlocked hd1905 is rather hard to find at this moment and the price gets jacked if you can, while the T-Mobile one is easy to find and much lower usually. I just was hesitant because of this. I'm using Visible and am quite happy with them and don't want to move.
[OnePlus 7T Guides, News, & Discussion] agentbob123:
Yeah, I originally wanted the 7 Pro, but I didn't move fast enough and it went out of stock both at OnePlus as well as T-Mobile. Then I checked OnePlus, and they no longer had the 7T in stock, which was quite a bummer. It's still on the site, so they might get more stock, but it's probably not likely. Some of the T-Mobile stores in my area didn't have the 7T either, but I found one that did.

I'm probably getting the bootloader unlock bin from OnePlus later tonight, as submitted that request a week ago. I'll try to remember to update my results.
[OnePlus 7T Guides, News, & Discussion] carnivalrejectq:
There is a site that will alert you when it comes in stock. I watched it stay in stock for about 5 mins one time, and actually put it in my cart, but didn't pull the trigger for some reason lol.
[OnePlus 7T Guides, News, & Discussion] agentbob123:
So I've completed your steps, but I experienced a couple issues along the way that might be beneficial to point out here.

TL;DR:

reserve.img failed to flash

last 3 images need to be flashed via fastboot

d

(I know you reference this, but it might be a good thing to give it more attention

those with out of date fastboot tools (especially Linux) might run into trouble

I primarily use Linux, so I took the flash-all.bat file, removed the CMD syntax, made it executable, and tried running it. For some reason, that failed, saying that it couldn't find any of the files. After fiddling for a few minutes, I just ran each line manually. I got through the first block well enough, excepting one:

It couldn't find "reserve," and I think that's because /dev/block/by-name contains reserve1, reserve2, reserve3, and reserve4 but not reserve_a or reserve_b. In the end, it SEEMS fine that I wasn't able to flash reserve, but I don't know what that bit does, so I'm not sure if it will cause any problems down the road.

The second issue I ran into, which stopped me for a few hours, is once I got to "fastboot reboot fastboot" and flashing system.img, vendor.img, and product.img - attempting to flash each of those failed with a similar "remote: Partition not found" error.

After some research around the web, I found that people experiencing similar errors were experiencing those because they were in fastboot, not fastbootd. My adb & fastboot tools seem to be out of date, which seems to be my distro's fault. I booted to Windows and downloaded the tools there, and tried again. This time, I was successful, and the device booted to the Global version (yay, no blinding pink boot logo!).

On a tangent, is there a way to replace the default OnePlus boot animation?

---------- Post added at 06:49 PM ---------- Previous post was at 06:02 PM ----------

Gotcha. Anyway, the file came not long after I sent that last message to you, and as of now, the phone is completely updated to 10.0.9 on Global firmware, as well as rooted! I haven't completely finished migrating from old phone to new yet, but I'm mostly there. :) I posted another message in reply to the OP with a few hiccups that I experienced, but overall I accomplished the job.

I've just followed this guide to go from TMobile to Global 10.0.9 and it worked perfectly. After completing the setup and installing apps I noticed that a number failed to install (Netflix etc) which I'm assuming is due to the unlocked bootloader status. I attempted to relock and the device then failed to boot, showing just the "your device is corrupted..." message.

I've seen mention of needing to be on a stock rom for this to work. Would it work if I downloaded a completely stock version from the oneplus website and install it using the local upgrade process?
[OnePlus 7T Guides, News, & Discussion] evnsio:
For anyone else reading, it works fine. Downloaded a stock rim from the oneplus support website and installed it using the official local upgrade system in settings. After a reboot it came up fine, at which point I booted into fastboot, ran 'fastboot oem lock', and after the standard full system wipe it came up fine.
[OnePlus 7T Guides, News, & Discussion] awr128:
I think you have to relock the bootloader right after installing the global ROM, with no data restore or apps downloaded. That's what I did and it relocked fine. As for the corrupt device, just unlock the bootloader again and you will be fine.
[OnePlus 7T Guides, News, & Discussion] FruitSidewalk59:
i was supposed to get the unlock token from oneplus today. its been 15 min over the 7 day and still no email. this is what i see on the oneplus unlock token website:

Status : Applied

Update time : 2020.05.31 22:04:21

Does the status change when they email / approve the unlock?

edit: just got the email. It was 26 min late. All good now

Status : Finished

Update time : 2020.06.07 22:30:00
[OnePlus 7T Guides, News, & Discussion] FruitSidewalk59:
The conversion from tmobile to global stock 10.0.9 went fine. But to relock the bootloader I had to do a local upagrde of the global stock 10.0.11 (to avoid the corrupt device error i got from just relocking after flashing 10.0.9). The local upgrade from 10.0.9 to 10.0.11 took 5min and then rebooted to fastboot mode. Then ran 'fastboot oem lock' and it worked!!

Thank you devs. Im now on global rom!!!!!!

[OnePlus 7T Guides, News, & Discussion] android_dan:
I have a question. I'm looking at a 7t T mobile phone that is unlock from t mobile. So reading here I see mention of an unlock code that one has to wait for. Are these two unlock code one in the same or do I need yet another code from OnePlus? Thanks
[OnePlus 7T Guides, News, & Discussion] kevinyohh:
T-Mobile asks for an unlock code that you have to get from your SIM unlocked 7T in fastboot mode, by typing the command "fastboot oem get_unlock_code", assuming you have set up fastboot on your computer. That will return a long code like the one in the picture. That's the unlock code you have to input in the T-Mobile request, with your email and IMEI. After that, it's just a matter of waiting.
[OnePlus 7T Guides, News, & Discussion] awr128:
Your phone is only sim card unlocked, which means you can use another company's sim card in your phone for service. You still need to unlock your bootloader to install the global ROM, and that's what the code is for that you send to OnePlus.
[OnePlus 7T Guides, News, & Discussion] android_dan:
Thanks. Was afraid that was the case. By the time I get the phone and wait for a unlock code I'm really close to the release of the 8 lite. Guess I'll just wait and see what that looks like.
[OnePlus 7T Guides, News, & Discussion] mrtoddles11:
Which instructions did you follow for this? There's the original (post #4) and also the shortened version (post #1) now. I don't need root, just trying to go to the stock global ROM, currently stuck on 10.0.3 and the phone won't update for some reason. Thanks!

All i did was unlock bootloader and flash latest global rom and relock bootloader and it worked just fine currently typing this on global 10.0.11 HD65AA rom
[OnePlus 7T Guides, News, & Discussion] nolimit78:
I wondered if this might cause a problem! Yes, you'll want to follow the post #1 as the instructions have been updated. Originally it was thought that flashing to the Indian ROM would help some issues with signal but I don't believe that ever panned out. I did it because the forum was kinda new and the info was spread across several threads. However after a few users here in this thread and myself found that the post#1 will works just fine.
[OnePlus 7T Guides, News, & Discussion] kompheak:
So I went ahead and follow the instruction. Download global rom from the link provided. 10.0.09 global. Extract the file and instead of writing the command to flash it. I just double clicked it and it went through the process. Phone boot up but there's no Wifi or Data. Is the file corrupted and need to be download again? Or it just doesn't work with that global rom

I'm coming from T-mobile 10.0.08. Sim Unlocked and bootloader unlocked

My other question is. Should I just create an empty folder and extract the rom to an empty folder and run flash-all.bat from there? Cause what I did was I extract the rom in the same folder as adb tool where it already have fastboot, adb, and many other files. Think because of that my flash was mess up?
[OnePlus 7T Guides, News, & Discussion] kompheak:
Also I like to add what my fastboot is showing after I flash 10.0.09. Is that normal? Its showing FC 23
[OnePlus 7T Guides, News, & Discussion] kompheak:
Disregard everything,, everything is fine now.... Lol don't touch the phone when it says waiting for devices
[OnePlus 7T Guides, News, & Discussion] kompheak:
Is the modded boot.img provided by op universal? Could that be use with the rooted instruction provided even I have build OP7T_O2_BETA_O5.

OnePlus device boots, doesn't seem to flash properly

My OnePlus 7T HD1907 HD63CB doesn't seem to want to flash properly. It is unlocked and all, but when I flashed both the 10.0.8 and 10.0.9 versions (Indian versions to get WiFi and Data working), it still had the T-Mobile boot animation and firmware. I can't perform a local upgrade either, and now I cannot access WiFi or Data. It does say that the device has no MAC, IP or Bluetooth address.

Note, I couldn't get the flash-all.bat working on Linux, so I basically redone it as a .sh script. Not sure if it worked properly, but I bet that's what's causing the issues.

I always wiped the device right before I flashed in case the wipe all command didn't work in the process.

[OnePlus 7T Guides, News, & Discussion] kompheak:
Assuming bootloader is unlocked - grab the global beta one. Go into fastboot and check that it's detecting your device. Once it detect... Just double click FLASH-ALL.BAT. and let it do it's thing. You'll know it's done when your cell boot itself back into the phone start screen.... Mine took like 10min.
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
Indian is no longer a necessary step, but yes, you can. It will wipe your data, though, so best to do it after flashing the global ROM.
[OnePlus 7T Guides, News, & Discussion] XD-MOD2-9MM:
Sounds like you flashed everything from bootloader and not fast boot. The correct screen you should be on before you select flash all should look like the recovery home screen. Which is actually fastboot now. Bootloader and fastboot have been split up. When you are in bootloader, adb reboot fastboot
