[OnePlus 7 Pro Questions & Answers] LexApp:
Please can someone help me out? The TMobile app on my device says the device is unlocked and I did receive carrier SMS welcome from other carriers when I inserted non-Tmobile SIM. However, after converting to Int'l version, the device failed to display network signal. Off course the device detects that a sim card has been inserted but no signal. The flat SIM icon with white fill color changed to a white outline without a fill color. All these happened within a day. I've since revert back to TMobile firmware and TMobile unlock app still says device is unlocked but I still get the same white outline sim icon. Any idea?
[OnePlus 7 Pro Questions & Answers] jcsww:
Is the non-T-Mobile SIM you are trying to use activated? Does that SIM connect to a network using bands the device has available to use? Is the network you are trying to connect to available where you are?

I don't recall the provider, but some carrier SIM's don't work until the device is updated to a newer firmware. Make sure you have all of the latest updates installed for whatever firmware you are running.

The latest T-Mobile firmware though introduces the mess the 10.3.2 brought to the non-carrier version though. Try manually scanning and connecting to the network. You can also put the device in Airplane mode for a couple of minutes to see if it will connect after that. Why OnePlus let such a horrible mess out to the public is beyond me, but 10.3.3 doesn't fully fix it.
[OnePlus 7 Pro Questions & Answers] swapavi:
I had the same problem. Once you convert to intl firmware, take the update to the newest version of the OS and you'll have signal again.
[OnePlus 7 Pro Questions & Answers] Vossti:
You guys are awesome!!!!

I followed the steps ...hit afew snags along the way... Almost thought I'd bricked it at some point then i gave it another go....

T.mobile single sim now a fully functional unlocked dual sim!!
[OnePlus 7 Pro Questions & Answers] LexApp:
Yes my non-tmobile SIM is activated. It's my regular SIM and when I insert it on my old defective 7 Pro, service pops up within seconds.

I've done everything you suggested, manual scanning, went back to Tmo firmware twice with no result. Yet device says unlocked on Tmo software without SIM service and the same SIM works well on the other 7 Pro, at the same location and time.

Perhaps, it's a software issue.

Thanks, I haven't tried this. I'll try this when I get off work today.

Edit: I tried [MENTION=6348343]swapavi[/MENTION] suggestions and it worked like a charm. Convert from TMo to Int'l and there was no sim service. Then took all the updates, popped in the sim and viola, the service came up. Thanks swapavi, you all are amazing.
[OnePlus 7 Pro Questions & Answers] totonebadass:
Am having the exact same issue as above -GM1915 (T-Mobile variant) converted to International and then to European. Reverting to T-Mobile gives "already unlocked" message in the T-Mobile app but still no signal. Have tried everything.

I messed around with the original partitions without backing up so am afraid I might have deleted some partition (like the token unlock one).

Is anybody with a GM1915 sim unlocked converted to international willing to send me all their partitions? (except data) - IMEI info can be scrubbed (can help with that). I have a suspicion about why it's not working.

If so send private message.

Am willing to donate to get it working. (Should my suspicion pan out I will post info to forum)

Help me bring my paper weight back to life, it's a great device. Pretty please.

PS: IMEI is not blocked or anything. I checked.

Or at least the qcn file (without IMEI info).
[OnePlus 7 Pro Questions & Answers] jcsww:
What are you using to flash? I used the MSM Tool to flash mine. My bootloader is locked, I am SIM unlocked, and never had any issues.
[OnePlus 7 Pro Questions & Answers] totonebadass:
I used the same thing, from the conversion tutorial, I also unlocked bootloader (currently re-locked).
[OnePlus 7 Pro Questions & Answers] jcsww:
How are you doing your OTA's? I always use the full image pulled down from Oxygen Updater over WiFi and apply it locally.
[OnePlus 7 Pro Questions & Answers] LexApp:
Anyone with TMo unlocked device and is having sim no service issues, perhaps this may help.
[OnePlus 7 Pro Questions & Answers] totonebadass:
I will give full OTA image installed locally a try (not sure if I did that already so I will retry it). Cheers!
[OnePlus 7 Pro Questions & Answers] swapavi:
I'm trying to use the ops patcher (ran as admin) and I keep getting the error "There was an error applying the patch: 0x80070057 (The parameter is incorrect.)

Has anyone here successfully used the patcher? I tried searching but, it didn't pull anything up.
[OnePlus 7 Pro Questions & Answers] zeeshee:
I have a T Mobile GM1915 which is unlocked and works fine in Canada. Its running 10.0.3.

Can i use instructions in post 1 to convert it to International?

Will it stay unlocked if i do that?
[OnePlus 7 Pro Questions & Answers] jcsww:
Flashing does not alter the SIM lock state, so it will stay unlocked if it is already permanently unlocked. The 21AA firmware works equally as well in Canada, at least on the Bell/Telus network.
[OnePlus 7 Pro Questions & Answers] zeeshee:
Isnt the firmware in post 1 Android 9? Shall i download the files in post 1 and flash them? My current version is 10.0.3. Please advise. Thanks
[OnePlus 7 Pro Questions & Answers] jcsww:
Yes, the firmware is Android 9 in the OP. It will flash fine. Then you can either OTA to 10.0.3.3 or use Oxygen Updater to download the full 10.0.3.3 image and update locally, which I would recommend over the OTA method.
[OnePlus 7 Pro Questions & Answers] zeeshee:
I want to root after this conversion. Should I unlock the bootloader before updating to android 10 after this conversion or I can unlock the bootloader later ?
[OnePlus 7 Pro Questions & Answers] jcsww:
You can unlock the bootloader by flashing the DP3 (Developer Preview 3) after converting. There is a thread for that whole process but it is very straight forward.

If you want to unlock the bootloader by requesting the token for support, which takes about a week before flashing to the 21AA firmware.
[OnePlus 7 Pro Questions & Answers] zeeshee:
Thanks for your reply. Do I need to request token? My t mobile app shows my phone is already unlocked and I'm using it in Canada.
[OnePlus 7 Pro Questions & Answers] jcsww:
You need to request the token through OnePlus Support and then flash it to your device when they send it to you with the instructions. Most don't want to wait though, so they just flash to DP3. There is no difference that I am aware if in the end, if you want the root.
[OnePlus 7 Pro Questions & Answers] zeeshee:
I'll follow instructions here as they link to this thread. One question. After I convert to international and unlock bootloader on DP3 can I update to latest build and then do root ?
[OnePlus 7 Pro Questions & Answers] jcsww:
Yes. Instructions on rooting the latest version of the firmware also exist in their own thread with links to Magisk and TWRP.
[OnePlus 7 Pro Questions & Answers] zeeshee:
My question is that can I update to latest Android q version and then root? Or I need to root on DP3 and then update to latest version?
[OnePlus 7 Pro Questions & Answers] jcsww:
DP3 is Android 10. When converting, you will be back on Android 9. Flash to DP3, which is a developer Preview of 10, unlock the bootloader, then update, then root.
[OnePlus 7 Pro Questions & Answers] zeeshee:
Since I'm in Canada will it be ok if I flash Canadian firmware. 10.3.3.GM21AA after DP3 in above step ?
[OnePlus 7 Pro Questions & Answers] jcsww:
Yes. The 21AA is the non-carrier specific North American firmware.
[OnePlus 7 Pro Questions & Answers] J3STUR:
Okay I been trying this guide for hours.... Am its finally installing right now. I kept getting sahara error and before that I got the open device error but what I did was....

1. Manually install the drivers qcser.inf and .cat

2. Open the Msm tool and uncheck sha256

3. Connect device to PC turned on and open cmd (Run as Admin)

4. enter the "abd reboot edl"

5. Hit start in Msm and this is where I got the Sahara error every single time. So I kept trying different things. Then I noticed it said "sahara error blah blah try to power off device and try again", so when the error is still there, hold volume up and power for 20 sec to reboot into android then hit the enter the "adb reboot edl" again and boom, starts working.

I hope this will help anyone getting the sahara error because I searched this thread and a couple others and no one mentioned to adb reboot edl again while error is still up.
[OnePlus 7 Pro Questions & Answers] swapavi:
I know this is a late reply, but you do not need to flash DP3 to unlock your bootloader. If your phone is already sim unlocked, you can just unlock the bootloader right after flashing to int firmware.
[OnePlus 7 Pro Questions & Answers] mr_ding:
Will this conversion works for Sprint 5G GM1925 model?

Bought a refurbished model online, turns out it was Sprint (Instead of T-Mobile), and using it in Canada.

So far, so issue. The only thing I noticed is whenever there's a software update.

I will get an error (when starting phone from cold-boot):

Configuraing your device

followed by:

Profile Update failed

The Device Configuration Has Failed

Contact Support

Clicking on 'Contact Support' gives:

Dialing page with '*611' as the number.

[OnePlus 7 Pro Questions & Answers] APJG:
Hopefully this is the right thread :p I'm in the US and just bought a used OnePlus 7 Pro GM1915 (T-Mobile) and I want to use this phone on Verizon (their models are 1917 Global/US Unlocked).

Here is what I (think) need to do:

Flash the International firmware

SIM Unlock the phone Looks like this was already done lol (says device is unlocked and usable on any carrier in the Network Settings)

Make sure CDMA-less Device Provisioning and HD Voice Calling are enabled on my Verizon account (from my understanding this was/is an issue on Verizon's end, even with the International GM1917 model, same as the issue with Verizon-to-Verizon calls, but the patch thread hasn't been active in over a year so I don't know if it's an issue to consider anymore).

Put my SIM in the OP7 Pro (it's a nano sim, so I don't think I need a different size)

Questions:

I don't need to unlock the bootloader or anything correct? I think I just need root to flash the International firmware?

Hopefully I'm not missing anything, but if I am any help would be awesome. Thanks!
[OnePlus 7 Pro Questions & Answers] ibdaman:
I bought a 7pro from T-Mobile last year, have since paid it off, and just sim unlocked from T-Mobile. I want to run stock OnePlus rom without TMO boot screen, apps, etc. Because I want the OnePlus ota updates as they're released without waiting on TMO. Can someone please help guide me in the right direction on how this can be done? And if it's even possible.
[OnePlus 7 Pro Questions & Answers] christianstudebaker:
I did all of this supposedly successfully but my device still says gm1915 and when I download the os update from oneplus and attempt a local update it says that it has failed. Any ideas what I did wrong?
[OnePlus 7 Pro Questions & Answers] jcsww:
Your device will always be a GM1915. If the software version is 21AA, then either you didn't download the right update, the update is older than the firmware on the device, or the update you downloaded is corrupt.
[OnePlus 7 Pro Questions & Answers] christianstudebaker:
The software does say 21AA. I haven't installed any updates, this is the one I was left with following these steps in the guide. Do you know how to fix this?
[OnePlus 7 Pro Questions & Answers] jcsww:
Use Oxygen Updater to download the latest full image update over WiFi. Make sure you get the 21AA. It will update locally through the update system in settings. Select local update from the 3 dot menu.
[OnePlus 7 Pro Questions & Answers] christianstudebaker:
I was already halfway through the download as you responded. Thanks for your input, much appreciated.
[OnePlus 7 Pro Questions & Answers] ctrlbrk:
Hi,

Have a OnePlus 7 Pro Tmobile edition. Sim unlocked. I followed the instructions and MSM flashed to the global version. Everything went fine up until step 8

On my Windows 10 laptop that I used to run MSM, I ran fastboot oem unlock but it just says "<waiting for any device>". Nothing more.

I rebooted, no change. I also tried on the phone in Developer Options to enable "OEM unlocking". That works fine, but it isn't clear to me if that is the same as step 8 (because it's listed as step 7).

Also, at the end, I go to System Updates and am told I am on the latest version -- but that's Android 9. Before I flashed, I was on Android 10.
[OnePlus 7 Pro Questions & Answers] andrewoofas:
hello guys, did any one got the problem after convert the op7pro unlocked to the international version it didnt recognize sim/carrier any more. not as blocked sim shows just dont catch signal anymore already rolled back to tmobile version but didnt work.

does anyone has any suggestion or tip. i really will appreaciate it. Thanks
[OnePlus 7 Pro Questions & Answers] jcsww:
Have you updated to the latest firmware via full package using Oxygen Updater?
[OnePlus 7 Pro Questions & Answers] andrewoofas:
:D:good:

:good:

already did and on T mobile version my signal came back, now will try if that fixes to on internation version too. thanks for the reply dude really appreciate it.
[OnePlus 7 Pro Questions & Answers] syrusxd:
I've got a T-Mobile phone model GM1915 running Oxygen OS 10.0.5 as the latest available update and I want to flash the latest 10.3.3, is there anything I should know? This thread is a year old and I don't want to try flashing anything old that could break it.

edit: nvm it worked
[OnePlus 7 Pro Questions & Answers] jcsww:
Nothing has really changed if you are flashing with the MSM Tool. It will roll you back to Android 9. The easiest way to get back to Android 10 and update 10.0.3.3 would be to use Oxygen Updater to download the full image and then apply it through Local Upgrade from the System Update menu.

Unable to activate T-Mobile service or upgrade OS versions

After following this guide, I successfully escaped from T-Mobile's clutches and am on Android 9, international version, however I am unable to activate my T-Mobile service or update OxygenOS.

1. After inserting my unlocked T-Mobile SIM during device setup, it infinitely loops (waited 10 minutes)

2. After inserting the SIM, my LTE service is not functional.

3. After attempting to input APN information for T-Mobile LTE, I get the screen "Access point name settings are unavailable for this user". Connecting to wifi, rebooting and saving the APN profile doesn't remediate this issue.

4. After attempting to download the latest build from OnePlus and copying the zip over to the root of my Oneplus, performing a local update results in the message "System update installation failed."

Here are the system logs after I tried all of these steps: https://drive.google.com/drive/folders/1PWNBCL_mwD7_jhvtrtMFlkHO2VASGHGf?usp=sharing

Any help would be greatly appreciated.

My MSM tool keeps hanging at random places during "Downloading system.img to system_a". Do I just keep restarting the process til it catches?
[OnePlus 7 Pro Questions & Answers] jcsww:
Try a better data cable and possibly, a different USB port, like one on the backplate of the motherboard.
[OnePlus 7 Pro Questions & Answers] mbarry55:
That did it. It took 3 different cables and 2 different usb ports to get MSM to work, then another cable altogether to get my PC to recognize it in fastboot to unlock it. I was losing my mind thinking I messed something up. Thank you!!
[OnePlus 7 Pro Questions & Answers] rafe83:
Will doing this re-lock the sim? I'm thinking about buying one that's unlocked.

I am going to try this tomorrow but I don't understand the future proofing update part. I still kind of new to this. What is that part for exactly?

Same thing happen to me when i flushed the international version signals all gone its not catching the signals so should i go back to tmobile and try upgrading or some thing (if thats the case where can i find the flashing file for that ) and if i can try some thing else let me know thanks guys

another thing i saw out of order was that both sims imei no is same no difference where as i thing it should be different for both the sims
[OnePlus 7 Pro Questions & Answers] jcsww:
Because dual-SIM functionality wasn't intended for the T-Mobile version, it only has one IMEI number, even when the second SIM slot is activated.
[OnePlus 7 Pro Questions & Answers] muz_dani:
so can we use the second sim or will it be blocked eventually as two sims will be used with the same imei ?
[OnePlus 7 Pro Questions & Answers] jcsww:
Two SIM's with the same IMEI work fine on T-Mobile. I can't speak for other carriers, but Sprint and Verizon both use your IMEI for service so I'm guessing it wouldn't work on those networks if you had two SIM's for the same network. I personally have 2 SIM's for T-Mobile though in my single IMEI OnePlus 7 Pro from T-Mobile and haven't had any issues over the past year and a bit I have had it and converted it.

i've got the gm1915 tmobile 1+ 7 pro. if i do this international rom flash...

-will i be able to use dual sim (once i get the physical dual sim on amazon)?

-do i lose any bands like 71 that i currently have?

-do i need to contact tmobile to unlock since it is locked to tmo right now?

-do i get all OTA updates still?

-any negatives to doing this international rom?

my main thing is to get dual sim to use here in USA to have 2 phone lines on the same phone. thx.
[OnePlus 7 Pro Questions & Answers] jcsww:
You will be able to use the Dual-SIM capability after flashing to the 21AA firmware.

No! Band 71 is included with the 21AA firmware.

Yes! The device needs to be SIM unlocked before flashing if you plan on using another SIM that isn't from T-Mobile. The device can only be SIM unlocked on the T-Mobile firmware through the Unlocking App that T-Mobile processes your unlock through! There is a T-Mobile SIM Unlocking thread here that you will want to check out.

You will get updates for the 21AA firmware normally, just like you would if you had purchased that version.

Make sure you use Oxygen Updater to update it with the full OTA download after flashing. Some people don't have service after flashing until updating to the latest firmware. The quickest way to do this is with Oxygen Updater, downloading the full image, and flashing it through the local update option.
[OnePlus 7 Pro Questions & Answers] lightrules:
thanks much man. also, under my SIM/network settings, if i go to advanced and network unlock, it shows the tmobile logo and says my device is network locked. i try to do a permanent unlock and it says failed and error 255 and that my phone is not eligible for unlock. i chatted with tmobile just now, gave them my IMEI, and they said it is not locked and ready to use on tmobile. i said you mean at&t sim will work? tmo replied, "your phone is ready to work with tmo and it is not locked." i dont get what they are saying. any idea here? and do i need to device unlock before doing this international flash? thanks!

[OnePlus 7 Pro Questions & Answers] jcsww:
It really isn't once you get everything (drivers, files, tools) setup and ready to go. There are different ways to flash as well but personally, I would suggest using the MSM Tool method to remain 100% stock.
[OnePlus 7 Pro Questions & Answers] lightrules:
i'm needing some help for the initial stages here. first time ever flashing a rom, so this is all new. i downloaded the 3 files. i then used 7zip to extract the 7z and rar files. i left the msm untouched. so i have 5 items in this new folder i created on my desktop. there is an L2 drivers folder that has 32 and 64 subfolders. also have 2 guac files (.7z and .ops), L2.+drivers.rar, and the msmdownloadtool patched alpha 3. so 5 items total sitting in this folder. what now?

is there a way to simply attach a screenshot here? i dont have an http link.
[OnePlus 7 Pro Questions & Answers] jcsww:
The device has to be in EDL Mode, which it will only stay for 10 or so seconds unless you start the flash. All files must be in the same folder, not in subfolders!
[OnePlus 7 Pro Questions & Answers] lightrules:
i think i did it. i think i now have the intl rom. hope i didnt screw it up. thanks [MENTION=3116388]jcsww[/MENTION] .
[OnePlus 7 Pro Questions & Answers] jcsww:
You can check in the About Phone. It will still list your device as a GM1915 but it will be running the 21AA firmware, if everything flashed.

[OnePlus 7 Pro Questions & Answers] DutchLuck:
I purchased a locked T-Mobile OP7 Pro. I thought I was going to be okay, but realized I misread one of the guides. Is it impossible to sim unlock without T-Mobile's intervention? I tried to reach out a couple times to T-Force with no luck. In the original post, "Sim unlock is still being worked on." Was anyone in the process of figuring this out, or did the that get scrapped? I know a couple users had been helping, but original account info was needed (I obviously don't have). The phone is nearly in perfect condition, so I just want to make sure I've tried everything before attempting to get a refund and just buy an unlocked version. Thanks

A little question. Do I need to unlock SIM before convert to international version? Because I found that OEM Unlock button is still grey and unable to switch on international version.
[OnePlus 7 Pro Questions & Answers] jcsww:
Yes! You need SIM unlock if you plan on using another carrier's SIM. You can flash the DP3 to trip the OEM unlock without the SIM being unlocked but the SIM lock will still be in place. The only way to remove the SIM lock on a T-Mobile purchased device is on the T-Mobile firmware.
