[OnePlus 7 Pro Questions & Answers] ThisIsCheez:
Today I received a T-Mobile, SIM unlocked, OnePlus 7Pro GM1915.

I have already followed the steps to flash international firmware and that went fine. Only issue I had was my SIM was being detected but no service, an OTA update to 10.0.3 fixed that issue. I haven't had a phone with root access/unlocked bootloader since my 1st gen Moto X so excuse my ignorance if some of these question are common sense, but I've done some searching online and can't find any straight forward answers.

1. Now that I have installed the international firmware I don't need to get a bootloader unlock from T-Mobile, correct? I can just use the OEM unlock option and unlock via fastboot?

2. I know bootloader/root can sometimes cause certain applications to not function, but I've also read Magisk has a setting to correct this. I'm mainly just concerned with Google Pay, is there a method for it to still function with root?

3. Part of me would actually like to use the phone stock for a week or so to see if I even feel like I need root access. I am currently on OS 10.0.3, if I update to the newest OS (looks like 10.3.1 is the newest) will I still be able to root with Magisk? I would assume yes since you can do an OTA update and keep Magisk, but I just wanted to verify.

Again, sorry if some of this is common sense, but I've searched around and can't find straight forward answers fort any of this.

Worked but...

I was able to convert with no probs but now i have no cell signal. any ideas?

disregard now working again,
[OnePlus 7 Pro Questions & Answers] jcsww:
You will either have to apply for the bootloader unlock token from OnePlus or flash to DP3.
[OnePlus 7 Pro Questions & Answers] Haz3:
Is it possible to take a TMO variant and flash to international firmware then relock the bootloader?
[OnePlus 7 Pro Questions & Answers] RandomPooka:
Possibly, but I don't know if it can be recovered with the msmtool if something goes wrong after locking the bootloader
[OnePlus 7 Pro Questions & Answers] jcsww:
The MSM Tool doesn't require the bootloader to be unlocked for flashing. You do not need to unlock the bootloader to convert with the MSM Tool.
[OnePlus 7 Pro Questions & Answers] RandomPooka:
Yes, I know. I just meant that I don't know if the phone will be able to get to EDL with a locked bootloader and international firmware on a non-international device. If you can't get to EDL, you can't use the msmtool? Not saying it WON'T work, just that I don't know if I'd be willing to take the risk of locking my bootloader on anything other than what the physical hardware is meant to be running.
[OnePlus 7 Pro Questions & Answers] jcsww:
The device I am typing on currently was a T-Mobile OnePlus 7 Pro converted to the International firmware, then converted back to have it SIM unlocked them converted back to the International 21AA firmware again. You can go back and forth. EDL is separate from the OS. That is why you can still boot to EDL when the device fails to boot in most circumstances.
[OnePlus 7 Pro Questions & Answers] jamescable:
So, I have a Sim locked oneplus 7 pro T-Mobile. All I need to do is use man tool to flash international. Install MP3 to allow boot loader unlock then I can flash twrp? Correct?
[OnePlus 7 Pro Questions & Answers] jcsww:
Yes, but that will not remove your SIM lock. You must remove the SIM lock on the T-Mobile firmware if you plan to use another carrier's SIM before flashing or you will need to. Flash back to the T-Mobile firmware to be able to SIM unlock the device.
[OnePlus 7 Pro Questions & Answers] jamescable:
I don't care about Sim unlock. I just want to unlock boot loader so I can flash Roms. So I can do this and still use T-Mobile while its Sim locked?
[OnePlus 7 Pro Questions & Answers] jcsww:
Yes, but only with DP3. Otherwise, you need to be SIM unlocked and then request the token from OnePlus, which can take around a week depending on how busy their support is.
[OnePlus 7 Pro Questions & Answers] jamescable:
That makes no sense. I should be able to go to DP3, unlock bootloader, install twrp, install Havoc os + root and still use T-Mobile service on T-Mobile branded phone. The phone is Sim locked to T-Mobile service
[OnePlus 7 Pro Questions & Answers] jcsww:
You can still use your T-Mobile SIM without being SIM unlocked with an unlocked bootloader. I was just pointing out, the only other way to unlock the bootloader without flashing to DP3, requires SIM unlock and requesting the token from OnePlus. If you flash to DP3, you do not need SIM unlock or the token to unlock the bootloader.
[OnePlus 7 Pro Questions & Answers] jamescable:
Gotcha. So where is DP3? I'm getting ready to convert to international
[OnePlus 7 Pro Questions & Answers] jcsww:
There is a thread for the Developer Preview 3 (DP3).

So I got dp3 booted with unlocked bootloader but can't seem to boot twrp. And yes, fastboot boot "twrpnameoffile.img

How did you get twrp to boot on dp3?
[OnePlus 7 Pro Questions & Answers] madmattco:
Ok so. If I have read this right, this will effectivly make the phone what appears as an international version. Even give it the ability to use the dual sim. But I do have a few questions.

Firstly, I bought another op7 pro from ebay. It was an unlocked t-mobile version. I do have 2 phone services. One with at&t and the other with visible. In the past, I had to run the 21.O.16_OTA_016_all_1908281716_b2bb5 ota to enable visible support.

I read on the OP that if I wanted to update from an ota, I would have to patch the ops file. Is this still applicable? Also, do the latest international stock roms keep the visible support?
[OnePlus 7 Pro Questions & Answers] Saml01:
This should be an easy question to answer. What is the OPS file and what does it do to the tmobile ROM that is onboard?

Why does it have the lineage os designation, guacomole, if it's supposed to be a one plus image?
[OnePlus 7 Pro Questions & Answers] zeamort:
Hello,

I hope this post finds everyone doing well. I recently purchased a used OnePlus 7 Pro from ebay here in Canada as a gift for my father. It arrived today and had T-Mobile messaging. I was unaware of all of this T-Mobile shenanigans (I had purchased a OnePlus 3T new a while back and was impressed with it, so I thought to recommend it as my father's new phone). I found this forum post after a bit of research but I still have a few questions that I would appreciate if anyone here could clarify for me:

1. The T-Mobile OP7 is unlocked and worked with my Rogers sim card. The phone also updated to android 10. Is there anything big that is blocked off as things currently sit?

2. If I were to go through the process provided in this post, would I need to manually update the phone each time, or will it notify my father that a new update is available and allow him to download and install as if he had bought an international version to begin with?

3. Off topic, but do you have any recommendations for anything else about the phone I should look into to ensure it doesn't lock or become any less functional in the future. I want to make sure that if there is a problem, I return the phone to the seller and look elsewhere for a phone.

Thanks in advance everyone, I wish you all health and safety.

I just wanted to share my experience. I just switched to TMobile from Sprint and got 2 OnePlus 7t's. I immediately looked up this guide to get started and found out about the sim lock problem. I do NOT have my phone paid off AND TMobile is paying off my 2 Sprint phones after a trade in. I have had these phones for less than a week and I got TMobile to sim unlock me within 15 minutes. Basically this is what I found out. Everyone now has a "support team". If you call within normal business hours, you'll get this team. After normal business hours, they redirect to China/India/whatever-land. The "support team" is who you want to talk to. There are very ignorant about tech and how things work. I got iPhone users who were simply amazed after I threw around terms like "Qualcomm chipset" and "Exynos". I basically told them that I am a developer and I got this phone because it's a developer friendly phone. I have to develop apps that run on ALL networks, not just TMobile. In order to test the apps I build, I have to be able to use those sim cards. They understood what I was saying and within 15 minutes I had my phone sim unlocked. Now I have oem unlock checked, but I'm currently waiting on the unlock.bin file from OnePlus which I'm told will take at least one week.

I just wanted to share my experience in hopes that it helps others. As you can see from the screenshot, I'm not lying. Thanks for this guide which I will be using as soon as I'm able.
[OnePlus 7 Pro Questions & Answers] bob24260:
A few questions, but first thank you for the time you've invested in help all of us. Apparently I'm not looking in the right places because I can't find a solution. I've been going non stop for 3 days on this and am at its end. My 7 pro is my only device and being without it is quite an inconvenience. My fault and my fault alone though. Long story short, I got a tmobile 7pro that had already been converted to international. I unlocked the boot loader and proceeded to bork everything that could be borked via my incessant need to tinker. I soft bricked and ended up having to restore to tmobile software. When the restore was done via MSM I had no signal period. I tried reflashing several times no signal still. So I figured I needed to go back to international but I can't for the life of me get it to flash. I get the packed image not exist error no matter what I try. I downloaded both packages via mega from this thread and since there was no msm tool in the archive I've tried every version I can find and still get the packed image error. Any advice? As I said I've been at it for 3 days and am at its end. I have no problem donating to yourself or anyone else who may be able to help get me up and running again. Thanks in advance!
[OnePlus 7 Pro Questions & Answers] Mervingio:
Nice but unfortunately this is not my case I looking everywhere to how can sim unlock but not see much service for unlock online for One Plus
[OnePlus 7 Pro Questions & Answers] abadasstanker69:
The guy that made a post about unlocking for free is still doing it. He says you have to get it whitelisted first. He was the first one I reached out to. But after a 15 minute conversation with TMobile, I had it done myself. Maybe try calling the TMobile peeps in New Mexico directly? I saw you were having problems and I targeted my post specifically at people in your situation. I was stunned they allowed me to do it so easily. I simply said I work for the post office developing apps (which is true) and I needed a developer friendly device. I specifically got a OnePlus for this reason since they are the most developer friendly company available on TMobiles network. It was truly that easy. Keep trying. I'm sure you'll get it eventually.
[OnePlus 7 Pro Questions & Answers] Mr_Tadakichi:
Do I need to be on a specific oxygen os version prior to this?
[OnePlus 7 Pro Questions & Answers] jcsww:
No. You can convert from any current firmware version of the T-Mobile firmware.
[OnePlus 7 Pro Questions & Answers] jamjr74:
I do not see a inf file? Which one is it?
[OnePlus 7 Pro Questions & Answers] Mervingio:
Ok I already converted and unlocked bootloader so I can use the MSM TOOL again not matter the BL is already unlocked?
[OnePlus 7 Pro Questions & Answers] jimlightner:
okay followed all the directions msmtool said download completed.rebooted phone everything works but I cant turn on unlock bootloader. button is still greyed out...what did I do wrong?
[OnePlus 7 Pro Questions & Answers] jcsww:
You should have flashed to DP3 if you want to unlock your bootloader without having to request the token from OnePlus Support after having your device is SIM unlocked.
[OnePlus 7 Pro Questions & Answers] jimlightner:
Do you have a link to the dp3?and can I do it now that I'm converted to international?
[OnePlus 7 Pro Questions & Answers] jcsww:
You can still flash to it. There are a couple of Developer Preview 3 threads with links that are buried under a few pages.
[OnePlus 7 Pro Questions & Answers] jimlightner:
Cool thanks for the advice.. I'll look for it..is there a guide or do I just dl and use local upgrade?
[OnePlus 7 Pro Questions & Answers] jcsww:
There should be a guide with the threads.
[OnePlus 7 Pro Questions & Answers] jimlightner:
Found it and it worked like a charm..thanks for the advice..unlocked,and rooted..

Not sure what happened but I used MSM TOOL to start from scratch but the phone now not read my sim card I reverted to MSM TOOL from T-Mobile same factory reset nothing I put mi sim on my OP6T boom no problem

Any ideas????
[OnePlus 7 Pro Questions & Answers] rhaudiogeek:
Newbie with Tmobile Oneplus 7 Pro that is locked to Tmobile.

Will flashing the phone to international version allow me to use the phone with Verizon?

Do I need to unlock the bootloader to get it network unlocked so I can use it with any other carrier.

Thanks and appreciate any help.
[OnePlus 7 Pro Questions & Answers] jcsww:
Flashing your device does not alter the SIM lock state of the device. You can either request an unlock through T-Mobile or try the T-Mobile unlocking thread.
[OnePlus 7 Pro Questions & Answers] saneaous:
Where can I find this thread?

Can you please confirm if flashing a new modem will unlock the device?
[OnePlus 7 Pro Questions & Answers] jcsww:
The thread is called, Need to unlock your SIM T-Mobile users? Here's how!.

What do you mean by unlock? Flashing the device does not rove the SIM lock. If you want to unlock the bootloader, you can either request the token to do so from OnePlus Support or flash the DP3 build.
[OnePlus 7 Pro Questions & Answers] adrianqwerty99:
This work for any OP7 pro? Cause i have the sprint 5g version
[OnePlus 7 Pro Questions & Answers] jcsww:
You will completely lose 5G if you flash the non-5G firmware.
[OnePlus 7 Pro Questions & Answers] adrianqwerty99:
And with this i can unlock the sim? I mean, can i use my phone with other carrier
[OnePlus 7 Pro Questions & Answers] jcsww:
Flashing does not remove the SIM lock. You need to rove the SIM lock before flashing if you plan on using the device with a different carrier.
[OnePlus 7 Pro Questions & Answers] fndpena:
Guys, I'm completely new to OnePlus phones and I just got mine today. It's refurbished OnePlus 7 pro, which was listed as T-Mobile variant, but phone is unlocked. I have 2 apps from T-Mobile: one named "T-Mobile" and the other one "unlock" that when I run it gives me a message saying the phone is permanently unlocked (check the screenshots).

So I believe my phone is still running T-Mobile firmware, right? I added a screenshot of my "about phone".

I'm running android 10, March security update. Can I still use the same files from this thread? Or that's only for android 9? I'm really lost, I'd appreciate some help. Thanks!

[OnePlus 7 Pro Questions & Answers] jcsww:
Yes. So far, none of the newer firmware versions have prevented cross-flashing.
[OnePlus 7 Pro Questions & Answers] fndpena:
So, once I do this, is permanent?

Will I be able to do OTA updates straight from OnePlus?

Will I ever need to use that tool again or I'll be free to just use my phone free of t-mobile stuff?
[OnePlus 7 Pro Questions & Answers] jcsww:
It's permanent until you flash it back. You will get OTA's from OnePlus regardless. The updates from the T-Mobile firmware still come from OnePlus. However, you will get OTA's normally for whatever your firmware is on. If you are on the 21AA firmware, you will get OTA's for the 21AA firmware.

The T-Mobile firmware OnePlus texting app has RCS built in to it through code in the modified version of the OS. If you want RCS on the stock OnePlus firmware, Android Messages is your best bet.

Can I use a type-c to type-c cable to do this?

I don't have oneplus original cable unfortunately, when I try to do adb reboot edl, it reboots (stays on black screen for a bit) and boots the phone again to android.

I was wondering if it could be the drivers...

EDIT: So, I installed the official drivers (the ones available inside the phone, when you connect to PC it appears as a mounted CD). Still, when I try to reboot to edl it just goes back to android after a few seconds on black screen... I think the problem is the cable... Can someone confirm the cable MUST be the original one from oneplus or we can use any other quality cable?

Btw, I used to have a Pixel 3a before and used to flash stuff using the same computer... maybe it's a matter of conflicting drivers?
[OnePlus 7 Pro Questions & Answers] jcsww:
The device will not sit in EDL mode unless flashing. Open up the MSM Tool before rebooting the device into EDL, press start after unchecking the the 256 thing, then reboot the device and connect it. If everything is installed correctly and unzipped correctly, it will flash. The screen stays blank in EDL and do not unplug it after flashing until the device reboots.
[OnePlus 7 Pro Questions & Answers] fndpena:
Worked like a charm! Thank you very much!
[OnePlus 7 Pro Questions & Answers] jcsww:
Glad to hear it. You should have a bunch of OTA's. Whether you update normally or through Oxygen Updater is up to you, but I would suggest a full OTA image from Oxygen Updater is the better way to go to skip multiple updates.

If. You plan on using the dual-SIM capability, you can order a replacement dual-SIM SIM tray from Ebay or many other places.
[OnePlus 7 Pro Questions & Answers] tgoods24:
Edit Again...: I was able to download the international version successfully. I was mistaken before thinking the Qualcomm Driver was not what you want. For this to work successfully you need your driver to display 'Qualcomm HS-USB QDloader 9008' in device manager. So i want to post about what i did to help anyone else seeing similar issues. Uninstall all OnePlus related drivers in Device Manager when you show hidden drivers. I found 3 more drivers that i originally missed from my old OnePlus 6T. Not sure exactly what the drop name was, but may have been devices (or something that started with 'D') and portable devices. I also redownloaded the MSM tool and checked MD5. Lastly, use the volume button method to boot into EDL. Before I was using ADB to boot into EDL. Not 100% if this did the trick, but it was the only time i was successful.

Sorry for previous panic posts. Hopefully this can be useful for someone else.

Edit: I was able to boot into recovery and power on device as normal (T-Mobile). Now I have have made several attempts to try to flash the international firmware again, and each time getting stuck on Param Preload. I have uninstalled all the drivers, re-installed Oneplus Driver, re-installed the certificates for the L2 drivers, rebooted PC multiple times, but every time my OP7P is in EDL Qualcomm driver is displayed in Device Manager. I have uninstalled the Qualcomm driver under hidden drivers in device manager and re-installed L2 drivers but my phone still downloads Qualcomm while in EDL and hangs on Param Preload.

Any help would be appreciated. FYI - I have re-downloaded OPS file and checked MD5, no changes.

Having issues trying to convert my phone from T-Mobile to International. When i was trying to flash using the MSM tool, I was stuck on the Param Preload for ~30 min. I tried to follow the steps to uninstall the Qualcomm driver and install the L2 drivers, but im not having any luck. I am on a Windows 10 computer, original usb cable, and my OP7P is now bricked.

When I try to boot into EDL, my computer acknowledges I plugged in an usb device. My device manager shows "Unknown USB Device (Device Descriptor Request Failed)". I tried to update the drive mapping to the L2 Drivers but no luck. Still displays the same message.

Any help will be greatly appreciated. Right now i have a brick for a phone :'(. Do you know where i can get the inf file OP refers to for the drivers? the only files i have for the L2 driver are system files.
[OnePlus 7 Pro Questions & Answers] mumboender:
Just a shot as I had a similar issue, the original cable did not work for me, I switched to a short TB3 cable and it completed. Not sure if your computer had USB C only, but a dongle didn't work for me.
[OnePlus 7 Pro Questions & Answers] sixzerohertz:
Hey guys when downloading the archive I noticed the md5 and ops file checksum are completely different. Is this normal?
[OnePlus 7 Pro Questions & Answers] swapavi:
Just used the msm tool to convert earlier today and it worked perfectly. Except now my phone doesn't recognize my sim card. I've tried erasing the modemst1 and modemst2 because I've seen that was supposed to help but it didn't so anything.

Anyone have any ideas as to why the phone can't read the sim anymore since converting? And maybe what to try to fix it?

Also, I tried to msm back to TMobile firmware and it still doesn't recognize my sim card. So now I'm back in international and rooted but still can't actually use my phone.

Edit: taking an OTA update brought my service back. Strange...
[OnePlus 7 Pro Questions & Answers] mumboender:
Exact same thing happens to me when I move back and forth from T-Mobile firmware to international and vice-versa. Phone won't let me put in my APN for AT&T and acts like it is sim locked. As soon as I take the OTA it recognizes my AT&T sim. Strange behavior.
[OnePlus 7 Pro Questions & Answers] maddangerous:
What step are you referring to? I did not see a checksum anywhere to check against in OP.

Edit: i see it, nvm. have to investigate.

Are you checking against the compressed file, or the ops file uncompressed.

---------- Post added at 09:03 PM ---------- Previous post was at 08:35 PM ----------

They don't match because the md5 file is for a different .ops file it seems
[OnePlus 7 Pro Questions & Answers] tylerjakob:
Hey. My Tmobi SIM unlocked phone comes in tomorrow and i was confused about a few things after reading the post and much of the thread.

My first confusion is about step 7&8

"7) Enable Developer Options and enable OEM Unlocking.

8) Enter bootloader mode on your device and type "fastboot oem unlock"."

I have seen tutorials where people do not do these steps. are they needed? If so, how do i "Enter bootloader mode on your device and type "fastboot oem unlock"." Type where? Enter how?

My second confusion is about Download mode drivers installed, adb and fastboot

just the driver the phone installs when plugged in? what i adb and fastboot? ow to install? install on what?

so excited to get this done! ty for the help!
