I cannot see the images in the post in my browser. I think I've read somewhere that we have to make sure adb and fastboot packages are up to date. I personally extracted the ROM archive into the platform-tools folder I downloaded from here.

I also observed that while the script was running and the phone rebooted, it did not go into fastboot automatically. It was stuck on the initial black screen with the language selection. However, that did not seem to affect the script so I just left it as is without distrubing it.

Unfortunately, I've given up, as now if it's left on for more than a few minutes, it heats up to the surface of the sun. T mobile is going to exchange me out with a refurb model. I've done everything I can the way the steps say to, but it will not get past the part where it says "failed: cannot see partition a".

Maybe another phone another time i suppose. I just don't get why this is so difficult.

This is what I get. I ve tried all possible combination of MSM Download and Fastboot roms. Always that system.img partition not found.

I ve done it. This hotdogb_14_O.20_201011 MSm Download brigs you to Stock Global ROM from T Mobile HD1907 . Choose as target O2 or if you want Idian ROM choose India.

Hi ,

I just ordered 7T from B&H (HD1907), - correct me if im wrong - so i wouldn't need to follow all this thread to unbrand, unlock and flash in order to get OTA updates?

thanks
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
From what I understand, if it's not carrier-branded, it's most likely the global ROM already installed, so you should get OTAs directly from OP.
[OnePlus 7T Guides, News, & Discussion] Skywalker168:
Once a t-mobile phone has been bootloader unlocked and flashed with global ROM, is it practically considered a "unbranded / factory unlocked" version? I mean, can I directly use OOS ROMs "not meant for t-mobile variant"? I guess I'm not sure why we need to boot into modded-boot.img first and then install magisk. Why can't we flash the modded boot image directly?
[OnePlus 7T Guides, News, & Discussion] k9r4n16:
Hey, might be a dumb question, but once I SIM unlock on one OnePlus 7T, does that mean it will still be SIM unlocked on another device? Is it the device that becomes SIM unlocked, or the SIM itself? I already did a SIM unlock on my previous device, but got smashed up and had to get another one.
[OnePlus 7T Guides, News, & Discussion] clsA:
the unlock is only for the exact IMEI, the Sim has nothing to do with it
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
The "SIM unlock" in question unlocks the phone to use any SIM from any carrier, Hence why they require your IMEI.

If I were to buy a new, factory SIM unlocked T-mobile 7T right now what would that mean as far as converting to an international variant with dual SIM? Would it still get regular updates from OnePlus or would it still go through T-mobile? I like the blue variant and it's so much easier to find from T-mobile than regular unlocked.
[OnePlus 7T Guides, News, & Discussion] CaptRicXT912:
Hi OnePlus+ ace's , I am trying to open MSM and it keeps telling me I " don't have packed image. " what is missing? maybe someday all this grey area in my head will make some sense.. lol

I picked up the Oneplus 7t "T-mobile branded" phone black Friday. (got it on Dec 4, 2020)

The amount of BS required to "Un-brand" the phone is HUGE..

Points of failure:

- Must run command program in "Administrator mode"

- Must set default USB preferences to "Data Transfer"

- Unlocked has many meanings...

- Use on any Network

- Sim unlock

- Bootloader unlock

- unlock token from Oneplus...

you need Sim unlock to get T-mobile Unlock code, to get Oneplus unlock token

- Windows 10 may not allow you to run fastboot_windows.exe program...

- Error code "This app can't run on your PC" To find a version for your PC, check with the software publisher.

Solution unknown...

Have tried the following"

- Run on another laptop

- Setup a new administrator profile in windows

- Left click on exe files, run "Troubleshoot compatibility" reverted settings back to windows 7

- Watched many YouTube videos on how to fix problem with no luck

At the moment I am stuck at the point of getting the "Unlock code" from the phone.

I can not seem to get the "fastboot_windows.exe get_unlock_code" to work in the command prompt window.

Error code "This app can't run on your PC" To find a version for your PC, check with the software publisher

I have sunk a man week of time trying to fix this problem.

I am willing to send $$ to anyone who can help me fix this problem.

I just returned my Oneplus 7t T-mobile branded phone. I was not able to unlock the bootloader.

B&H Photo is sending me the non-branded version... Cost $30.00 extra. Well worth the money. They made the return easy.
[OnePlus 7T Guides, News, & Discussion] Superorb:
Yeah B&H is where I was going to order from but was being cheap. $20 would be worth it if I didn't have to jump through a zillion hoops.
[OnePlus 7T Guides, News, & Discussion] rikyxie:
Lesson from me: Be sure download the latest stock room and ADB. Unzip the stock room, and copy and replace all files from ADB to the stock room folder and run [.\flash-all.bat] from there.

Without doing this, I kept seeing "Flashing is not allowed for Critical Partitions" error while flashing on some of the files, and still get back on T-mobile version after finish.
[OnePlus 7T Guides, News, & Discussion] blushrts:
thank you for the great guide!
[OnePlus 7T Guides, News, & Discussion] Coolearn:
I finished the same procedure and it is successful.

Only difference is system version, the original TMO version was 10.0.3, it was OTAed to 10.0.12 when I wait for unlock_code from OnePlus. so I unlocked the bootloader on TMO 10.0.12, and directly flash to Global 10.0.13, OTAed to Global 10.0.15.

Relocked the bootloader on Global 10.0.15 is successful. I tried on Global 10.0.13 before OTA, it was failed with "your device is corrupted".... after OTA and relock, everything is fine. (Boot warning/NetFlix...)
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
This should be added to the OP, @nolimit78. This sounds like it'd be really helpful for others in future.
[OnePlus 7T Guides, News, & Discussion] blushrts:
Or if you copy the rom files to your ADB folder, don't overwrite anything and you'll be ok. I learned the hard way as I overwrote them and it failed the first time.
[OnePlus 7T Guides, News, & Discussion] orangepowerpokes:
Same experience here. Only hickup was not looking at my phone display for bootloader unlock confirmation...I thought I had unlocked the bootloader with fastboot on the connected pc. Folks - when unlocking bootloader be sure to interact with your phone when issuing the fastboot commands 😄
[OnePlus 7T Guides, News, & Discussion] DuckMySick98:
Sorry for monopolizing the discussion.

Anyway I finally success to flash.

I will resume what I did maybe it will helps someone else:

I was following this tuto: https://xdaforums.com/t/t-mobile-7t...thout-unlocked-bootloader-sim-unlock.4153943/

then I came here and followed steps:7, 8 and 9.

But I had some problem after launching the Flash-all.bat, it was showing me T-Mobile screen and no wifi or data working. Just go in your settings and enable adb debugging then reboot on bootloader and just reflash your rom. It will work.

And if you want to relock your bootloader, for me, I had to do OTA update from 10.0.8 to 10.0.15 if no it was showing "device corrupted".

And note that I didn't root.

[OnePlus 7T Guides, News, & Discussion] handydandy:
I have the exact same issue. Seems it has to do with the recovery partition. I'm not sure how to flash in the recovery partition though.

Edit: So far I've narrowed down the issue to be that TWRP is unable to mount the system partition.

Should I try another recovery img instead of TWRP?
[OnePlus 7T Guides, News, & Discussion] glenb77:
i like many had same problem. reading along other thread may have been something to do with the fact i was using amd based laptop. but basically it is not going into fastbootd on the rebooting to fastboot after the vbmeta img gets flashed. for me i solved it by doing it in linux. i took flash-all.bat and made it linux script and it worked. for some reason i had to flash it twice before network (wifi and sim) worked. but very happy w/phone now. if you are desperate you could use live linux usb, boot with usb, get android-tools pkg installed and open up command prompt and make script from other or just type commands in bat file one at a time or maybe try on an intel based windows machine and most recent fastboot.exe
[OnePlus 7T Guides, News, & Discussion] BS20:
WOW THANK YOU!!! I went through the trouble of extracting an OTA from the OnePlus website, hooking up Py3, extracted the .bin using payload_dumper. and trying to flash each .img file. that is not the way to go.. Flash-all.bat is whats up. Is there a way to make a Fastboot zip out of any OTA? and how do you get fastboot to flash and re size system.img and find and write different sections of one partition? Thanks again, My OP7T is now T-mobile free. Merry Christmas!

Everything ran smooth on my Envy x360 AMD Ryzen5, just make sure you add "platform tools" to the PATH in your environmental variables.
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
The "flash-all.bat" file almost never works as there's one file it can never seem to flash, and iirc it just stops the batch file process entirely, so it's usually best just to copypasta the commands one-by-one.
[OnePlus 7T Guides, News, & Discussion] prakhar26:
Hey Guys. I am very new in this and i am not even a developer. I almost tried for 9-10 hours and finally was able to Accomplish the task. I went trough all the possible failure, learnt it and overcome it. If any one need any help , i can explain in layman term. Thanks for all the help. CHeers.

PS- I was able to unlock the device first and change it from Tmobile to Global firmware.
[OnePlus 7T Guides, News, & Discussion] GuyInDogSuit:
There is some speculation that certain chipsets (ie, AMD vs Intel) that seem to mess with the flasth-all batch file. But try running each command one at a time, rather than running the bat itself. Just be sure to wipe first. I think you have to be in fastbootd, too, iirc.

I think the main reason why people recommend this is to make sure the modified boot img will boot first. Then once its proven to boot, do a direct install. If your sure that your patched boot img is good then I dont see why you cant just flash through fastboot. There are so many patched boot img files floating around and sometimes people download the wrong one, flash it, and have all kinds of issues. Just make sure your boot.img file came from your specific ROM

Well I flashed the magisk_patched 10.0.8 international.img after reboot I installed the app-debug.apk (magisk canary installer) but now it does not pass safety net.

Also how come I do not see the option to hide magisk neither navigation menu with modules install?

EDIT

The problem is if you use the magisk_patched-10.0.8-international.img it worked but the manager made me upgrade from 20.3 to 6db88d8ad(21201)

and after that it broke not sure why? I think I di direct install maybe shoud it be done on the inactive slot

EDIT

Never mind probably to much beer at new year I did again everything is cool.

CRUD MONKIES. So, I did the process. Everything was fine. Then I relocked the bootloader. And now it just keeps saying

Your device is corrupt. It can't be trusted and will not boot.

And I can't re-unlock it.. The all in one tool is not detecting it... Really hoping someone is around to help.
[OnePlus 7T Guides, News, & Discussion] SuperEsteban:
The first time that I did it, it happened to me something similar, I unintended relock the bootloader (because I'm an idiot), so, I had to reflash it with the All In One Tool, that let me boot again, then I followed the instructions to unlock it again.
[OnePlus 7T Guides, News, & Discussion] Kediil:
Six hours later and I managed to unbrick it. All sorts of errors and driver fits and sahara and smt. Not to mention my pc deciding it was time to blue screen on me multiple times.

How long do you wait ?

Cause i am still waiting and it's been 5 minutes.

The CMD is prompting < waiting for any device >

The phone is still on language selection screen.
[OnePlus 7T Guides, News, & Discussion] hypercoyote:
Make sure your USB connection to the PC is good. For me, it was just a couple of minutes before it picked back up. You might be okay to go ahead and Select English but I wouldn't make any other choices. When I selected to go to the Fastboot menu, that's when it messed up my connection.
[OnePlus 7T Guides, News, & Discussion] Lalulilelo:
I fixed this problem.

As I am on Windows 7, i had to manually install USB bootloader drivers in Device Manager.

Then on the OnePlus 7T, you have to stay on the "language choice screen" aka fastbootd but Windows detects the fastboot device now.

Edit :

So if anybody faces this <waiting for any device > problem, it is likely a USB driver problem.
[OnePlus 7T Guides, News, & Discussion] hypercoyote:
I'm curious how you began the process initially. You should start off at Fastboot before rebooting to the language menu. Were there two sets of drivers?
[OnePlus 7T Guides, News, & Discussion] Lalulilelo:
Yes.

Are you in Windows 7 ?

I think Windows 7 has trouble identifiyng this device in his various modes (adb, fastboot, normal).

Right now, I am rooting my OxygenOS Global and I am having problem using adb while in TWRP.

EDIT :

While in TWRP, sometimes the phone appears in Device Manager then disappears.
[OnePlus 7T Guides, News, & Discussion] hypercoyote:
Nah, I am on Windows 10, but I still had to install the driver pack to get Fastboot to be recognized by Windows, so that's why I was saying I was curious how you got even that working without the drivers.

I decide to forego TWRP for now. I do know that some have had issues and had to get a specific version of TWRP to handle what I think was the split recovery partitions or something like that. If you do some googling it should turn up some results on it because I ran across them with my issue of the recovery_b not being found during the Global ROM install.
[OnePlus 7T Guides, News, & Discussion] Lalulilelo:
I had the drivers.

But Windows 7 did not make the connection latest drivers <-> ONEPLUS 7T when the phone was in certain states.

It was good enough for fastboot but not for fastbootd.
[OnePlus 7T Guides, News, & Discussion] hypercoyote:
Did you install the drivers that are available on the phone itself, that show up whenever you connect the phone to the PC? If not, can you provide the link where you got your Win7 drivers for anyone else who may need that?
[OnePlus 7T Guides, News, & Discussion] Lalulilelo:
I did use the Samsung USB drivers https://samsung-usb-driver-for-mobile-phones.en.softonic.com/

but I think OnePlus one would have worked too.

You have to manually select them :

in Device Manager -> Right Click on desired device -> click Update Driver Software -> Browse my computer for driver software -> Let me pick from a list of device drivers on my computer

Here you can untick "Show compatible hardware" if you don't see the drivers you want to try.

I did not try the Oneplus Drivers this way but I guess they would have work and that Win 7 was just having trouble making the connection between hardware and drivers.
[OnePlus 7T Guides, News, & Discussion] hypercoyote:
Ohh, so are you saying when you initially connected the OnePlus in Win7, it wouldn't even pop up the drive with the Drivers on it?
[OnePlus 7T Guides, News, & Discussion] Lalulilelo:
No.

It did not work only in fastbootd mode (fastboot reboot fastboot -> language selection screen).

Other than that it was OK.
[OnePlus 7T Guides, News, & Discussion] the_link_8:
hi i already did the whole process but when i tried to relock the bootloader i got an error saying the system was corrupted and the phone was stuck on that screen so i unlocked the bootloader one more time and it started to function. again and everything is working great, what happens is that I wanted to convert my phone to the international version and re-lock the bootloader so that I can have the advantage of having the international version, so is there a way to re-lock the bootloader and keep running the international version?
[OnePlus 7T Guides, News, & Discussion] hypercoyote:
I'm interested in this as well. I left mine unlocked because of all the issues I've seen others have.
[OnePlus 7T Guides, News, & Discussion] thetoady:
so I bangged my head on this for a long long long time, kept on getting the critical partition error. I saw hint to load the fastboot firmwae with the all in one tool, instead of the script and that worked and I realized what was going wrong.

when you reboot the device with fastboot reboot fastboot it goes into that chinese/english part of the firmware, i was manually putting it back into fastboot mode (selecting fastboot). which seems to not be able to update the critical partitions. however, I noticed when i did the all i none, instead in that screen until it was finished flashing.

With that said I have a few issues with my conversion from t-mobile to global, which I'm hoping people can comment on (some minor, some larger)

1) it seems the t-mobile version had more icon packs (it seems op's global rom doesn't come with "any" (listed as such, but one can install from playstore, but doesn't seem to change much). it seems t-mobile lets you choose standard android icons as well. wondering if there's an icon pack that provides that (I hate oneplus's sms app icon)

2) I don't seem to have wifi calling option. Im wondering if this is because I'm running in a dual sim configuration?

3) I lost the google now screen to the left most side of my launcher, now its a oneplus widget holder.

from what I can tell #3 is to be expected.

A lot of people seem to have issues with #2 (some say it works for them, others say it doesn't) it seems oneplus dynamically chooses when to display it?

#1 is probably the least important (or easiest to work around), but it is annoying
