Question Flashing Global ROM to North American OP9 Pro question - OnePlus 9 Pro

If you were to get a dual-SIM tray and flash the global ROM to the NA OP9 Pro, would there be any issues using dual-SIM? Also, even if it did work, would there be any way that an update would remove that capability?
I've never flashed a ROM before, so please forgive my ignorance.

I was just thinking about this more, probably needs more than just installing a rom. probably a needs msm tool

I did exactly that (picked up dual sim tray, flashed EU OOS full) on my OnePlus 9 5g NA (AA) version, and the second sim still didn't read. As another member posted, it likely will require a custom MSM flash. I had hoped the TMobile conversion tool/procedure would work for that, but can't risk my main phone for now.

Q about 6GB 128GB version

Is the 6GB 128GB version exclusive to China?
All the Xiaomi websites that started revealing the Mi MAX 3 on their front page (which should be the international version) list the phone's spec with 4GB 64GB only.
If it's China exclusive will we be able to install the Global ROM when officially released on it as it will be specific to the 4GB 64GB version?
Thanks in advance.

I have a 6/128gb model here in the U.S. - the hardware should actually be identical aside from storage sizes, and I've had no trouble flashing anything. I can't imagine there would be any reason you couldn't flash to your firmware of choice as long as your bootloader is unlocked.
Thank you very much for your reply.
However, that is the case now as there is no Global Firmware officially available, but how if when this Global Firmware was released and intended only for the 4GB 64GB it might cause problems if it was installed on the 6GB 128GB if it was going to address the phone's memory sectors differently than the 4GB 64GB memory sectors.
The main question here is: are there two different firmwares for both versions or it's only one universal firmware that is used for both versions with different memory capacity?
Same SoC, same code name, RAM and storage size doesn't mather so same firmware/rom for both...
Have you seen different roms listed for both versions anywhere?
We can actually take this a step further. Since the redmi note 5/pro has basically the same internals as the mi max 3(less USB type c, larger screen), how hard is it to modify the Note 5 pros global stable rom to accommodate the mi max 3? The only reason for not going this route is to go directly to Android 9(Pie) development. My two cents.

If the two versions of the phone were different enough to require different firmwares, then they would have different code names - signifying what firmware to use for a device is one of the functions of a code name. Since they are both simply "nitrogen," this means they should take identical firmware. I've had a lot of phones and modded them all, and spend quite a bit of time reading forums for devices I don't own but am interested in, and if the two versions take different firmwares despite having the same code name then this will be the very first time I've heard of it happening. I am 99.9% sure that both phones will take the same firmware.
Yes, 6gb/128gb is a China exclusive and won't be released globally. same goes for blue variant. Any 6/128 "global" edition is likely to be a fake rom with forced unlocked bootloader. So u guys should beware.

So, the important question now, can we re-lock the bootloader on the 6GB/128GB China version after installing the official global firmware on it? because some have mentioned that the phone returns itself to unlocked state again after doing this.

Could you please tell us where we can find official source or confirmation for this claim?
Thank you.
I have waited so long for the 128GB Global Version and am starting to warder if it will truly come.
Please would you advise me to buy the Global ROM or still wait for the Global version as am not sure it will Come?
Coming from a 6gb/128gb owner: just buy the damn thing if you want it.
I personally don't regret it, saved myself the wait for the bootloader unlock, and would have installed Xiaomi.eu anyway, even if I had went for the "global" version.
Last but not least: there are no modem differences between the global and chinese model, so why wait if you end up getting the same band support anyway?

Agreed 100 % from a 6gb/128gb owner on 8.8.9 xiaomi.eu.
6/128 Gb Gold version here as well, on the so called unofficial unlocked 9.6.4.0 dodgy global rom. Been using it , giving it a hammering over the last couple of weeks.Fast and stable...no bugs to report.Not bothered in trying to update it.Everything seems to be doing what i want of it.
There will not be a Global Version of the 6GB/128GB variant as the phone is already available on the Xiaomi Global website and on the spec only listed is the 4GB/64GB variant.
It's all up to you to decide on which version you want, keeping in mind a couple of things:
First, no need to wait for a Global Version of the 6GB/128GB variant as it's not coming ever.
Second, there is no difference between both variants except for the memory difference (obviously) and how would you like your bootloader be locked or unlocked (with the Chinese version to stay on locked bootloader you'll have to remain on the Chinese Firmware pathway but if you want to go the EUMIUI or IMUI Global you have to unlock the bootloader, however, with the Global Version you can have the bootloader locked while you are on the official Global ROM with OTA updates working normally)

Hi
Good day sir
Please I need to understand you properly on this, am a novice here and am sorry for the way I will put my questions as below.
If I buy the Chinese version from aliexpress 6gb/128gb,would I get regular MIUI update from xiaomi and also newer android update without any tweak on the ROM?
The thing there is am not familiar with locked and unlocked bootloader as am scared of bricking the device at any attempt.
I just want to buy and enjoy my device without any tweak on rom
Also, I do read that the Chinese version, has mix up of language when tunned to English (has English and Chinese writing). How true is it?
Please I need answers before I make an order.
Thanks

If you are not going to modify your phones' firmware and stay on the original firmware then you'll be good to go and you will get regular OTA updates from the official Xiaomi servers but keep in mind that this would be the Chinese firmware pathway all the time for you.
The Chinese firmware has English language but as you said there are some here and there mix up but it will not interfere with your daily use of the device but it's there (you'll find some naming in the menu in Chinese)
The other thing, is that the Chinese version doesn't have Google Play or any other Google services but you can install these easily from an app that is available on a Chinese app store pre-installed on the Chinese version.
So, if you are ok with all of the above you can get the 6GB/128GB version but if you are not feeling much comfortable of Chinese lettering here and there and some Chinese apps on your device then go with the 4GB/64GB version.
By the way, there will not be much difference of performance between the 2 devices (if any at all) if you are wondering about that and for the storage the device has a Micro SD slot and you can have all the storage that you want with that.
Hi,

You should never listen to a vendor regarding this information without thorough research. That's why Xiaomi implemented the new 720 hour official bootloader unlock.

The Rom , like mine is official.The method they used was unofficial.As there is no 128gb International version phone in existence. You will always get a Chinese version 128gb phone, as seen when you check the IMEI software link. With the "Official rom" loaded by the person you purchased it from.
To do that, they had to unwrap the Chinese version phone, Install the "Official rom" and then send it to you.What they did wrong was state to you that the phone was in a sealed box.If you are concerned with having a Chinese version of the phone, i would suggest you try to return it and downgrade to the Official 64gb International version phone in a sealed box with the same software on board.
I Personally more than happy with my 128GB Chinese phone with the International Rom loaded.
I wouldn't have opened that dispute TBH.
The Chinese 6gb / 128gb model is still the best one on the market, and let's face it: you would have installed the Xiaomi.eu ROM on the "official" global version anyway, just to get theme support and rid of the ads.

Help! OnePlus 7T CN Version

Hello.
I found a good deal on a 7T 256+8 CN version, which is cheaper than getting it directly from OnePlus european store, where they only sell more expensive 128+8.
Few questions:
1. This is my first OP device, could anyone please tell me step by step how to install OxygenOS?
2. Switching between HydrogenOS and OxygenOS, do i need to lock/unlock bootloader?
3. Since the version i'm getting is CN 256GB, will the official EU OxygenOS build even work on the phone? Considering they only sell 128GB in EU. Won't it bug out?
4. After i flash OxygenOS, will it just work normally as it would with EU phone? Support OTA? No other difference in functioning?
5. Since the phone will be imported from China, will it have any IMEI issues or something hardware related? LTE bands are the same.
6. Any other things i should know about? I tried to think about all the could-be roadblocks, but any other tip is greatly appreciated.
Thanks!

Thanks for your reply. Just so i understand, i'm not looking to root the phone nor do i want to mess with the bootloader. All i want to do once i get it is to flash stock OxygenOS, latest version and completely remove CN ROM. From other info i gathered while browsing google, OP phones are one of the only ones that allow to switch from CN to EU ROM seamlessly without messing with any commands or programs.
From what i understand, i need to enable some option in developer settings, then download EU ROM from oneplus website, then in phone settings go to update-local update and just select the downloaded EU Rom? Can you confirm if that's basically all there is to it?
Much appreciated!

Question OOS 11.2.5.5BA/NA 5G/Dual Sim?

Hi all, I think I already know the answer to my question.... I just want to be 100% sure as my searches are not quite revealing my answer.
Like many...when I received my NA OP9Pro I was disappointed to notice it wasn't dual SIM. Sent it back and still waiting for a refund for almost 2 months now. (That's a frustration with OP in itself...makes me want to go back to Samsung....UGH!) Anyways, I currently have an LE2120 (Chinese Model) running OOS 1.2.5.5BA (European version) and I am well aware that out of the box the NA version does not come with Dual SIM hardware.
The question that I am not 100% sure of is would the software build still allow dual SIM? My gut strongly tells me no..
The reason why I ask is that currently I don't have access to 5G. I thought it was because my work SIM didn't have 5G enabled on the carrier, I was incorrect. I still don't have access to a 5G, just shows 2G/3G/4G. I thought maybe it is because I am using a EU build here in Canada where maybe the bands don't line up...I have done searches on why 5G isn't available but nothing seems to fix it.
Just a shot in the dark...for people much smarter than I am!
No, simply running EU rom on NA hardware does not enable dsds. You can setprop for dsds but it doesn't work properly, seems to wire the first sim card into both slots and cause a conflict
Maybe I didn't word my question in the correct fashion.
I have dual SIM hardware, in my case it is the Chinese Version but I'm told the hardware doesn't differ as it still a Global Version.
The question is NA ROM, on Dual SIM hardware. If the rom itself supports it. I would just try it, but then I have to wait for the next update.
If you have LE2120, then the EU build should get you dual sim
I have LE2120 and I'm switch to Oxygen OS and trying build AA/BA/DA all working with sim dual
About 5g .. i have same your problem no option 5g only 2g/3g/4g
First check your country bands support
First try:
*#*#4636#*#* and choose NR/LTE/CDMA/EvDo/GSM/WCDMA if not fix 5g
Another way to fix:
I'm fixed 5g same steps its was on op8p

So you have tried your LE2120 on AA? Dual SIM is all working ok?
I feel like switching to AA would get me unto the proper bands here in my country, but leary to do it because then I have to wait to the next build. Unless I decide to go root/magisk.
I did try the *#*# method, but that doesn't do anything. I have tried several different dialers and it never brings up this menu everyone talks about.

Question Convert to Global?

Hey Guys,
I have a Tmo Variant OP9 Pro.
I was able to get the bootloader/oem unlock done by going through the OnePlus website.
Now my question is, how do I convert to global so I can use Custom Roms. I'd rather convert to global than stay on the Tmo Version.
Currently on OOS12. I was looking at the thread below to convert your phone to global, but I want to make sure before I brick my device that nothing has changed and I should still be using the Global firmware 11.2.2.2? Do I need to get the SIM unlocked too? It's not currently.
Convert T-Mobile OnePlus 9 to Global (or other) firmware

Or is there an easier way now to convert to Global from OOS12 Tmo?

Question [Question] Where is the NA unlocked firmware?

I've read thread after thread and as best I can tell there is an EU version, a global version, an India version, and the T-Mobile version. The radios on the non-T-Mobile versions are different than the T-Mobile version (or so it seems).
What I have is a OnePlus Nine Pro from Amazon, fully unlocked, T-Mobile version. Works fine for me on T-Mobile. What I want is the unlocked firmware, as if I bought it in the US directly from OnePlus. Like the Nine that I got directly from OnePlus that I am returning because I want the telephoto lens and a couple other improvements the Pro has.
Since someone may ask, here is why:
Avoid bright magenta startup screen
Get patches more quickly
Get round icons
Debloated (esp. Qualcomm)
The feel of the phone, to me, is less than the Nine with stock unlocked firmware
The dialer is better on stock OOS 12
I don't want to lose the radio, I don't need an International version, I plan to stick with T-Mobile, so it seems like it should be easy, but I can't find the firmware. If the global version is the same as the unlocked, fine, but do I have to do weird things to keep the US compatible radio (like I read in various threads)?
Hardware version 22, software LE2127_11_C.19, if it matters.

Sorry, but if it is T-Mobile carrier, you have to unlock the bootloader with a token. There is a XDA thread on unlocking the T-Mobile bootloader if you are on a branded LE2127 model phone.

If you install any firmware such as the North American (Global) once the rom is installed you have to go into fastboot mode to unlock the bootloader. No rom comes unlocked....sorry!
This is what you want. Anything else and you risk breaking the radio.

I'm confused. Is the EU version the same as the unlocked version as sold in NA directly from OPO?
[edit], Yes I had read that and don't want to have to screw around with the modems; on the Nine I had several OTAs after unboxing it, the modem just kept working (on T-Mobile, who is my carrier). That page you reference says "You must flash the T-Mobile modem after every OTA" which is not interesting to me. And it talks about dual SIM, which I believe the NA unlocked version does not have (at least the 9 does not). So there is a firmware out there, presumably, that is different.
If I spent the extra money that I don't have on a new Nine Pro straight from OPO, I'd have the firmware I want. Instead I need to flash it, which is no big deal, but I can't find it. And I wouldn't have the pretty blue color : )
Of course I assume my experience with the Nine is the same as the Nine Pro, software-wise.

But you can't use the global firmware on the T-Mobile 9 Pro without losing the radio I thought? I figured that was the whole reason nobody has made an MSM Mod to flash the T-Mobile variant with global instead of EU software.

I'm confused. Is the EU version the same as the unlocked version as sold in NA directly from OPO?
[edit], Yes I had read that and don't want to have to screw around with the modems; on the Nine I had several OTAs after unboxing it, the modem just kept working (on T-Mobile, who is my carrier). That page you reference says "You must flash the T-Mobile modem after every OTA" which is not interesting to me. And it talks about dual SIM, which I believe the NA unlocked version does not have (at least the 9 does not). So there is a firmware out there, presumably, that is different.
If I spent the extra money that I don't have on a new Nine Pro straight from OPO, I'd have the firmware I want. Instead I need to flash it, which is no big deal, but I can't find it. And I wouldn't have the pretty blue color : )
Of course I assume my experience with the Nine is the same as the Nine Pro, software-wise.

The T-Mobile 9 Pro has a unique situation where it only works right with the T-Mobile modem. The T-Mobile 9 doesn't suffer from this issue and can use any 9 modem. The process here has been proven to result in a usable modem once the conversion is done. I don't believe the same can be said of using the NA global firmware.
This is what you need to do for the Global Firmware.

The word that keeps throwing me is "global". So if I spent the extra $300 and got it directly from OnePlus in the United States, I'd have the global firmware?
The few threads with "North American" aren't explicit [enough for my tiny brain].
I've been testing the (pretty blue) one I got refurbed, and it seems fine, so I'm keen to fix the issues I've mentioned, and I don't mind the work.
FWIW, most of the time I see "global" on xda, it is different from "U.S.".

It's Global due to it not coming preloaded with T-Mobile firmware. I believe the 2127 you have came sim and bootloader unlocked. I bought my 2127 directly from T-Mobile and had to request T-Mobile to sim unlock it and request a token to unlock my bootloader from OnePlus site due to it being directly from T-Mobile. So, when you convert it to the Global version it will remove the T-Mobile bloat.
9Pro directly from OnePlus site for NA is 2125 and for EU is 2123.

OK, so that's a "no", it won't be the same as the 2125, software-wise. It won't have the very bright magenta startup screen, it won't have the T-Mobile software pre-installed, but there will be differences (what?) from the 2125 firmware.
Right?
Is it possible to get/load the 2125 firmware?

Your phone will pretty much run the 2125 software when you convert the 2127. Won't have anything T-Mobile at all unless you install T-Mobile applications. The main advantage of it all is faster software updates rather than sitting around waiting for T-Mobile to update their software for 2127 branded phones. That thread I posted will help you convert your 2127 to 2125 (Global) BUT! Keep in mind to make sure you retain your T-Mobile modem.

OK, so it is "yes", but with a caveat for the modem. Which is weird because, as I understand it, the modem from OnePlus direct purchases would be fine and fully support T-Mobile. No way to get whatever that modem is [and have it work perfectly]?
Thanks for your time going back and forth, by the way.

The 2127 has a modem specifically with T-Mobile bands as I like to say built for the T-Mobile network. The 2125 has a modem that still works with T-Mobile, but doesn't have the extra bands that come with the 2127 modem. That's why you should retain the T-Mobile modem before converting to 2125

This.
Out of curiosity, if you know, does this apply to the Nine (non-Pro)? I'm used to getting all the T-Mobile bands, until I hold on to my phone so long the network changes.

No, it doesn't apply to the regular 9, just the 9 Pro.
I bought the 2125 Pro for use on t-mobile USA and it has global firmware. I looked on the official OnePlus manufacturer tech specs and it has all the LTE and 5G bands that T-Mobile USA says they currently use in their support site. I don’t understand what this is about a special modem firmware for T-Mobile. Is there something I am missing here?
