Turn wifi off on your phone so it doesn't detect any updates.

Part 1👇

1▫️Download OxygenOS 11.0.9.1 https://oxygenos.oneplus.net/OnePlus7TOxygen_14.O.35_OTA_0350_all_2206171459_e2cf457f577648a3.zip onto your PC. Rename it to .jar to .zip

2▫️ Then plug your phone into the PC & copy it to the (Root System) of your Android.

3▫️Now go to Settings -> About device -> Version and tap "Build number" 7 times. This will enable Android's built-in "developer mode".

Now go to Settings -> System -> System Updates -> top-right corner button select the cogwheel ⚙️ Select Local Upgrade and now select the Global OxygenOS 11.0.9.1 & let the Installation Finish.

Part 2👇

1▫️After installing OxygenOS 11.0.9.1 make sure to boot into Recovery Mode and perform a Hard Reset!

2▫️Power off your device. Press and hold volume down + Power button. (The device will boot into recovery mode).

3▫️Select language. Select Wipe data and cache > Erase Everything (Music, pics, etc) > Tap on "This can not be undone, continue?". Now Reboot system from "Reboot" option."

4▫️Now after you hard reset I would block updates with this guide https://xdaforums.com/t/guide-disable-system-updates-permanently.4592381/

I tried to break it down for you & make it a lil more easier to understand hope this helped.
[OnePlus 7T Guides, News, & Discussion] CaptRicXT912:
Thank You,, You did Great... Because what is understand now and I already had done the 11.0.9.1, But if I understand this correctly, the dwonload of - OnePlus7TOxygen_14.0.35_xxxxxxx is the > OxygenOS 11.0.9.1 That is what I was not clear about.. If I am wrong, Plz Correct me.. I say my confusion is I see OxyOs 11.0.9.1 vs. OP7TOxy_14.0.35_OTA being Two different OS's ?? But they are one in the same.. Appreciate your quick reply.. Since I have yet to do the Recovery / Hard Reset instructions.. I did not want to get ahead of myself.. Thank You.. very much..
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
That is correct OnePlus7TOxygen_14.0.35_xxxxxxx is OxygenOS 11.0.9.1 that is the original Package name & yes a hard reset is required after installation it smooths out the OS of bugs etc.. makes the phone run alot more stable.

After you hard reset I would block updates with this guide https://xdaforums.com/t/guide-disable-system-updates-permanently.4592381/

I want to Thank You for all the hard work and time you have shared and others like yourself who devoted to helping a novice like myself.. I did this process about three years ago and it seemed easier, but I was younger and smarter. lol . Now 73 getting older and slower. I am always amazed to those of you who figure all this stuff out . ..I had given this phone to a good friend, as I moved up to 8T.. and I forgot to warn hin Not to accept any Updates , but he did and when I could not reach him by phone for a few days , went to visit. and he told me what happened and no longer had Global, and was on Ver 12 single simm. I say Ouch.. let me have the phone and I will fix. And THANKS to You, I was able to put it back.. it did take me , ( don't laugh ) couple days of several hours to understand and figure how to get my laptop and the 7T to work together and your immense help and Steps.. again Thank You.. P.S. - I will now follow your last recommendation to secure the phone from future updates. Question - When should I do the "Lock the Bootloader", I do know before I set the phone up with the friends DATA..
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
After you perform last steps. I would recommend locking the bootloader ASAP. That's right.

1▫️Plug your phone into the PC, Turn USB Debugging on then Boot into fastboot mode.

2▫️ Open a cmd command prompt in platform tools root folder.

3▫️Type fastboot flashing lock hit enter.

4▫️It will say do you wanna lock your bootloader hit continue.

Your very welcome glad I was able to help.👍

[OnePlus 7T Guides, News, & Discussion] Barto604:
Hi I tried your method to convert my Oneplus 7T android 12 to global firmware.

everything was running smoothy until the part of flashing the "Flash-all.bat" file, for some reason i get the bat run the script successfully but when it boots the phone it still get the T-Mobile version of Android 10.

I tried to

- wipe clean the data on recovery. boot to fasboot and run the "flash.bat" but i get an error on the recovery Partition saying that there's no directory found.

- I tried to run the MSMDownloadTool to do the steps again but now my phone is not being detected by the program, ( it did previously before running the flash-all.bat step)

Currently boot OEM and bootloader are unlock ( I get an message saying that the bootloader is unlock before booting normally) the only problem is stuck on the T-Mobile version of Android 10 even though i run the flash-all bat multiple times.

I did all this steps while running windows on "Driver verification disable" and i double check device manager so im 100% sure the drivers are correctly installed.

update: when I try to boot on EDL mode it takes me to fastboot instead, I tried running the "adb reboot edl" command but platforms tools/cmd can't seen to find my device even though usb debugging is on.

Any suggestions I really appreciate it.

FIXED CHECK MY COMMENT THANKS TO Headcase0
[OnePlus 7T Guides, News, & Discussion] Barto604:
Will it be possible that you reupload the mega file, for some reason the link is invalid and I need that Qualcomm folder cause im experiencing the same issues as you before
[OnePlus 7T Guides, News, & Discussion] Barto604:
UPDATE: I follow Headcase0's post and run the Sh1t Flasher (funny name) they made and I manage to convert it to the GLOBAL version of OnePlus :D
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
The problem is not with the flashall.bat file... it's people not following the instructions! If you installed your USB drivers properly to begin with which is clearly stated before you started the tutorial. You wouldn't had any problems what so ever with the conversation & also never needed to follow Headcase0 post.

So make sure y'all are reading & following the directions that goes for everyone.👍
[OnePlus 7T Guides, News, & Discussion] Barto604:
Well I installed the USB drivers as you stated and everything worked fine until running your bat file. Then I tried Headcase0 one and it worked like a charm.

Either way thanks for the tutorial. 👍
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
All good whatever works for you. Just was stating it does work & you do not need headcase0 flasher. I've flashed my phone over 30 times with the stock mauronofrio flasher works just fine. Sometimes it takes a second try & yes having the correct drivers is very important. I dnt use the Google drivers btw I use the OEM OnePlus Drivers.
[OnePlus 7T Guides, News, & Discussion] spiderock98:
This thread save my life, thank you OP so much

btw at step 10. I have to run .bat file 3 times to make it work :)
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
Your welcome & that's what everyone has been saying about the flashall.bat file supposedly Headcase0 works better but I've never had problems usually flash's right over first try for me. I'll haft to re-convert my phone over again soon to see what's going on?
[OnePlus 7T Guides, News, & Discussion] Phantom Thief:
Worked fine here. Had to do the flash_all.bat 2 times as per instructed
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
See, if done properly it works just fine. Everyone take your time & read carefully. Glad you got it successfully converted over💯

Any upgrade for ANDROID 12? ota UPDATE AFTER THIS versuion is installed on t mobile oneplus 7t
[OnePlus 7T Guides, News, & Discussion] nabeelahmad909:
Many times i booted the fastboot screen while flashing 2nd time flash-all, here we need to wait for 2 3 minutes and dont manulay go to fastboot, it will flash on same screen i.e language menu after reboot.
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
Once you flash the phone the second time with flash-all.bat it will boot to (fastbootd) mode which brings up the language menu yes that's correct once it does that! Leave the phone alone when you see that language menu, it will continue flashing the global rom then your phone should reboot up & completely be converted over once flashing is over. Dnt forgot to follow every step after this ok every step in the tutorial matters. 💯

Now if you try flashing while in fastboot mode & it does not boot into fastbootd mode on the last flashing process then that means your USB drivers are not properly installed.

I've got a USB tutorial guide linked in the guide.
[OnePlus 7T Guides, News, & Discussion] jthawken123:
Help.

I didn't install the drivers correctly.

I'm a dumb-dumb, I know.

So here's where I'm at: I was able to unlock the bootloader and run flash-all.bat once. Now, my phone reboots (still showing the T-mobile screen) and goes to the "Hello" screen. When I reboot into fastboot, my PC doesn't recognize my device.

I went back and followed the instructions for updating the drivers, but since I can no longer access anything in the OS of my phone because it's not set up, I can't enable debugging mode or do any of the ADB stuff. So, I can only make it through step 8 of your guide to install the USB drivers (which, I admit, is only as far as I went when installing the drivers in the first place.) When I look at the drivers installed via Device Manager, I don't see any of the OnePlus drivers, nor do I see the "Qualcomm HS-USB QDLoader 9008" driver anywhere.

So, I can't access USB debugging or ADB stuff because my phone is not set up. When my phone is plugged in to my PC, it is an unrecognized USB device. After attempting to re-install the drivers, still no luck.

Can anyone help me with what my next steps are? I appreciate the help, and I recognize I did not follow the instructions clearly, and that is 100% what has landed me in this pickle.
[OnePlus 7T Guides, News, & Discussion] nabeelahmad909:
I used samsung cable with google drivers, Qualcom drivers manually added over from list of selected drivers method

Win 10 64 bit

will again try on win 11 also.
[OnePlus 7T Guides, News, & Discussion] EstebanLB:
This doesn't work for me. Pressing both volume buttons and then quickly inserting the cable doesn't do anything and the MSM tool(already started) stays the same without detecting anything. Is it posible that to enter EDL mode the buttons are vol - and power instead of both volume + and - ? or is there another way to enter EDL mode from abd while connected?

NVM: I didn't properly run the tool as admin
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
You

You getting stuck in a bootloop is a different story. You just needed the MSM Tool to get you back to stock firmware or you can simply use the Fastboot Enhance tool & flash over the same firmware while in fastbootd mode! Then proceed to root manually with magisk or use the patched boot.img to gain quick root access you already have of course there's not many reasons to root these days btw it's best to stay on stock firmware just my opinion from lots of rooting experience the iPhone would be more useful Cydia is way better, also stock firmware is alot more stable then custom roms etc.. Anyways here's the Fastboot Enhance Tool if interested - https://github.com/libxzr/FastbootEnhance/releases/download/v1.4.0/Release.zip

It can flash custom roms, official firmware,

Can extract boot.img & payload.bin etc.. way better then the good ole payload dumper. I introduce you Fastboot Enhance Tool v1.4.0 👍

You need to Boot into Android then open up device manager. HD1907 will be displayed in Portable Devices tab!

From the looks of it I can tell you installed your drivers properly because you are in fastboot mode & your bootloader is showing up in device manager 👍

No it will not work for HD1901 India Variant. But you can downgrade back to A11 to bring back the dual sim functionality!

I'm sorry, I checked the box and it's a hd1907 device made in India, after android 12 update it shows hd1901 and one sim stopped working, can you kindly tell me if converting would work and fix the issue?

alright I did everything, and everything went smooth except there was one message reserve failed during the 2nd flashall

and now I'm on android 10, still one sim, wifi broken and can't get in the system update for step 11 because when I click it the settings app crashes

can you kindly tell me what to do?
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
If it's a HD1907 then use the T-Mobile MSM Tool instead to downgrade the phone.

Then try the conversation process again to unlock the dual sim feature w global firmware.
[OnePlus 7T Guides, News, & Discussion] DinIslamJoy:
it is a hd1907 made in India, right now it it says hd1905 in about device for some reason

can't find any files for it
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
Ok so whether it says HD1905 or HD1901 that's ok we can still use the MSM downgrade tool to lower the firmware to the proper update on your phone.

⭐Downgrade HD1907 T-Mobile 🏩👇

1▫️Download OxygenOS 10 MSM Tool

https://onepluscommunityserver.com/list/Unbrick_Tools/OnePlus_7T/T-Mobile_HD63CB/Q/OnePlus_7T_T-Mobile_OxygenOS_10.0.13.zip

2▫️Run MsmDownloadTool V4.0.exe as Administrator.

3▫️Then click on Target select TMO!

4▫️Now hit Start on the MSM Tool.

5▫️Now put the Phone into EDL Mode👇

Turn the phone off completely! Take your OnePlus Cable plug the the USB side into the PC while leaving the Type C port unplugged from your phone. Now hold vol up & vol down buttons at the same time about 5 secs...while doing that plug the Type C port into your phone immediately❗

Do not let go of vol up & vol down while plugging the cable into your Phone!

6▫️The MSM Tool should now detect your Phone & start the downgrade process to Android 10.

7▫️Setup Android 10 & do not turn Wi-Fi on keep it off.

Once you Downgrade you go use the Conversation guide again to convert to Global Firmware https://xdaforums.com/t/guide-how-t...to-global-firmware-oxygenos-11-0-9-1.4558889/
[OnePlus 7T Guides, News, & Discussion] DinIslamJoy:
omg thanks a lot for the quick reply, what did you say after the end of t mobile tutorial? after step 8 do the conversion steps again or is it after step 6? basically go to android 11 and follow the conversion?
[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
Step 8 is just Formatting the phone right after installing latest OxygenOS 11 update which is needed because it makes the phone run a lot smoother, less buggy etc..

After downgrading back to OxygenOS 11 go try to convert to global again & at the end of the tutorial I highly recommend blocking updates you can use this guide here ▫Turn OFF Update Notications.

[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
I just remembered that update is for global so what you need to do is stay on OxygenOS 10 then go straight to the conversation guide to get on global.

So ignore the rest of the steps and go try & convert to global then once converted over then try & update to OxygenOS 11.
[OnePlus 7T Guides, News, & Discussion] DinIslamJoy:
thank you, going to try the conversion again

[OnePlus 7T Guides, News, & Discussion] xxlMVPlxx:
When you updated from Android 11 to 12, Did you have "Dual Sim" support? If so my best advice would be to "downgrade" back to (Android OxygenOS 11).
