Differences between European/US/International ROMs? - OnePlus 7T Questions & Answers

Hi
I haven't found anything regarding this. Could someone tell me the differences between the ROMs?
I actually use a Chinese H1900 variant with international OOS and I was wondering if there is any benefit for me to use EU as I'm in France.
Thanks

Not really, eu rom lacks equilazer settings due to European laws. India rom have some specific benefits like cloud service 5gb. Other than that only hardware changes is band difference. Tested all on my hd1900. Using international

I don't think even hardware is different, the bands are just turned off in the firmware.

Just about to get a 7T and will need to flash either Global / Europe - do you think the equalizer settings are worth going with Global (currently run Bass Booster as 5T doesn't have equalizer either) or stick with Europe as UK based ?

Was there ever a full stock 10.0.6 International ROM posted? I flashed the European version when it was found but want to do a clean install and use International. The OP website only has 10.0.3 in the support page.

Since you have the HD1900, if you flash the EU or International rom, does it unlock the other lte bands? I'm considering buying the HD1900 version but everything I've read states that it lacks the lte bands I need (61 & 71).
Thanks!

Its definitely lacks those bands. Use Oxygen updater app from play store, there can be downloaded all latest updates. Just see in the startup menu what rom is currently on the device. Under my dwvice menu oneplus 7t is for international version, oneplus 7t( eu) is for European version and last will be oneplus ( India) India version. Then go to 3 dot menu and choose version you like to install same naming as the step before. Then select in update method full update, or try incremetal update if you don't see latest version of software now will be 10.0.6. Just follow instructions in the app and you will have new android version faster than the others. Using international version for two weeks no problems on my hd1900 Chinese verion of the phone.

Don't worry those bands are needed only in rural areas in Usa from my knowledge by far. If you live in Europe flash international you will have equilazer unlocked. Some users seem to don't have equilazer unlocked, so you will find only if you flash yourself.
One more thing before flashing. you will need to have (older) or the (same) version rom varian. No posible to downgrade.

I discovered it won't let me flash from the EU version to the International version (both 10.0.6). It sees the International version as being older than EU and prevents the flash. If anyone has an idea how to force it I'd love to hear!

Indian version have call recording, cricket scores, cloud storage, caller identification, sms visualization and few more i guess.
Not sure which of these features have reached other versions now.

You will need to wait for full version of international in app. Now is available only incremetal and thats the reason you can't flash.

Hi, i have the 7t hd1903 model. Can I flash through the local updater the European firmware over the global one with a Locked boot loader? (of course with the same firmware version) thank you

I always thought it was mostly hardware variations rather than software - mostly due to the LTE bands differ depending on the region.
OP's made it so it's not as attractive to buy a phone outside your region due to that. For example, on the original OP7, they left out a few critical bands T-Mo and AT&T needed here for full LTE compatibility. It would still work on the other bands, of course, but it may not work everywhere the US version would.
I think that's stupid, personally, but it seems to be more for marketing than anything else. I think it'd be less hassle to just have one phone with as many bands as possible, then just put different software on it to comply with the legal requirements of those markets.

I have the HD1905 which is US. It has the Indian OOS installed and has the call recorder enabled which I need. Does the US OOS ROM have this feature that you can enabled? If not, can it be done with Magisk modules for call recorder?

That's interesting. What about EU privacy laws makes it that they don't allow an audio equalizer?

The OOS native recording module gives you call recording on the US ROM, it's what I use.
Save the zip to your phone
You need to uninstall the module prior to any oos update. You can reinstall after the update.

Buy oneplus 7t hd1900 Chine version in France

Hello
I plan to buy a oneplus 7t. I am in France and the only model sold is the hd1903 8gb ram 128gb.
I would like to buy the hd1900 Chinese model.
This model has 256 GB of storage.
According to the technical characteristics, the hd1900 model has the same technical characteristics, especially at of the LTE bands.
It comes with an oxygen rom of the French language and playstore installed.
I have several small questions to ask you.
1 / is this version of oxygen a version benefiting from updates via OTA?
2/ Is this model perfectly suited for Europe?
3 / buying a Chinese version, must you install a global version of oxygen os ?
4 / to root later a Chinese version hd1900, it is done in the same way as the European version hd1903? Or should I install a particular firmware?
Thank you in advance for your replies.
cordially
Ola,
while i do not live in France, i can help answer some of your questions as i order also from china and has the same model ordered.
1. Check what rom they flashed on the device. mine shipped with the indian rom. U can flash EU rom as long as the EU rom version is higher than the currently installed. So dont update when u first boot up ur device
3. some sellers, they are flashing oxygen version before they shipped it. In my case, i flashed the global rom after i receive it as i noticed that i'm using indian version (has cloud storage option in gallery).
4. there shouldn't be any issue rooting the device later.. that's what i think

thank you for your precise answer.
Coming from Xiaomi, I will start in the world of Oneplus.
To update in a version of Oxygen adapted to France and Europe.
Once you have downloaded the firwmare file, do you have to put the file on the phone in the update directory and force an update from the Oneplus settings?
Or should I use a particular software for this update?
Just put the whole rom in the root folder of the storage then update in the settings-system-system updates -"click gear icon" - local upgrade

Thank you for your reply.
For example if the version of oxygen os installed is the Indian version and I want to install the global version. I just download the global version I put in the phone and update as you indicate?
Should it reset the phone if updated to a version of oxygen os that is not same as that installed on the op7t?
No need to reset,. Ur only problem is if the version of oxygen os installed is the latest. In that case look for the thread in guide section on how to flash

Thank you for your reply.
But it is unlikely that this oneplus7T is equipped with the latest version 1.0.0.6 released a few days ago. I would normally have a newer version to install.
3 last questions:
1 / In my case in France, it is better to use a global firmware (faster update?) Or a version of the firmware EU (European)
2 / Oxygenupdater is a useful utility later for future updates?
3/ And can we make updates via Oxygenupdater if the oneplus 7T is rooted?
Thank's

1. Looks like global recieve faster updates, dunno what benefit EU firmware has as i'm not from there
2. Yes, for global 10.0.6, i have used oxygen updater
3. Oxygen updater will detect if ur rooted and will advice u to download and install the full rom.

Hellou,
I ordered this one ( https://bit.ly/343MpgU ) and it's comming to germany... its an "international" Version... what does that mean? ^^ And does it have an european plug?
Hi, also French, I received my OP7T 128GB beginning of this week and as far as I can tell everything is fine. I unlocked the bootloader easily, I updated OOS through integrated OTA system as OOS was already flashed. I did a reset after the update (just a bit paranoid ).
I'm still trying to root it as I couldn't achieve it yesterday. I fastbooted the phone with a magisk patched boot.img but then I couldn't install magisk from magisk manager. I begin to think my phone is actually with international rom and not EU. I have to check again but now I'm stuck with my OP5T as I don't have that much time to tweak my new phone. Feel free to ask anything...

@Zayatoshi: J'ai reçu aujourd'hui ce modèle 256 Go HD1900. La mise à jour 10.0.06 OTA m'a été immédiatement proposée et s'est effectuée sans problème. Le transfert direct des applications de mon Oneplus 5T au 7T s'est effectué presque intégralement. Sorry for my post in French but as I address a French...... Cordialement.
I bought my OP7T on Gearbest and it's Chinese 1900 variant, but it's running Oxygen OS. I assume that it was manually flashed to use Oxygen OS. How can I determine is it global or european software? Now I have 10.0.7.HD65AA
And can convert it to 1930, so system info would indicate it's 1930?

10.0.7.HD65AA could be indian or global rom, EU is something like HD65AB. Indian Rom has some cloud storage from oneplus so if you don't have that, you have international rom.
I don't think you can convert to 1903 (there's no 1930), it's most likely some hardwired value that firmware just displays.

The hardware is the same for all variants, just choose a ROM (all ROMs are supported) that is suitable for your requirements. I'm using Global ROM on my Chinese variant HD1900...

Yes, read instructions but I think you have to be in fastbootd first. Then double check the model number of your device and which ROM it comes with - it may be that the Indian ROM and global are the same or can both be installed on the same model, but I can't say for certain, I have global model with global ROM

I'm not 100% sure what you're referring to as it's been a while since I used the stock ROM flashing package but maybe the below will help? It's my understanding Global will work for Indian, Europe and North American models (mine was Europe, I used global) and Chinese / HK and T-Mobile have their own images. Sorry I can't provide these.
VariantsEdit
Both OnePlus 7 and OnePlus 7 Pro have several variants. The differences are usually with the supported bands.

Question Can I change my Indian Software OOS to the International/European OOS?

I posted this on OP9 forum but OP9 Pro forum looks more active, sorry in advance.
I bought a OP9 chinese model LE2110, my software is oxygen OS 11.2.3.3 LE25DA (indian)
I want global version because this one has some bloatware and indian company cloud notifications that i dont want.
Is it possible to change it to international version? i downloaded the global one but i cant install it (local) because its a downgrade or equal to my current one. i updated to the latest version when setting up my phone.
The chinese version/model doesnt have wireless charging, so if there is a problem with compatability, can I change back to the indian variant?
note: I dont care about my data i can format everything, my old phone still works and I can transfer all data later.

i think u can as i have changed from EU to indian OOS - i couldnt wait to try 11.2.4.4 lol
But the key is it must be later version that yr current OOS which means u are on 11.2.3.3 to EU 11.2.3.3 it will not work - that was based on my experience.
Agree with u the bloatwares are annoying.. perhaps i will go back to EU once a newer than 4.4 is out.
So far, all seems to work. I cant comment for 5G as its not available in my telcom

Wait so if a new update comes, and I DONT update. I can manually download the new international version from Oneplus website and do a local update? Then It will switch to the international version?

I know you have the non pro china model but just to know, you have after switching to oxygen does the following are working?
5G, 4g+ (carrier aggregation), volte, google pay? and in which country are you?
Oh I just did local upgrade from India 4.4 to eu 4.4, it works.. So I think u can downloading and do it. Worst case, use oxygen updater and change back to global and revert
I see.. when you switched to eu 4.4, did it remove Cloud Service (indian version has this advertisement)? or Red Cable Club?

Sorry I just read your message.
I didn't switch to oxygen, i think the seller did the switch and shipped it to me.
4G works, 5G doesnt work. Im in Saudi Arabia.
I don't use google pay but there is NFC.
Check Signals/Bands for each phone version, and the signals and bands that your carrier use. You can find them in the specifications for each phone

Hi there, is there any way to force installing also an older version of EU OS?
I mean via fastboot or magisk?
No it's not possible i was confirm about it from multiple experts even from lightweight tennis stringing machines experts too but it's not working.

Question LE2120 Chinese variant has Indian FIrmware ((LE15 DA). Is it possible to change it to global firmware?

I got my 9 pro yesterday and it has indian firmware which i don't like. Is it possible to change it to global one. I'm on 11.2.5.5.
Also is it possible to use msm tool for Indian variant on this handset?
Thnx. Really hoping to get some answers
It should be, you should be able to download the global firmware from OPTeam's list of them and just flash in local update.
Yes, you can.
The only problem is 11.2.5.5 is too new, there is no full upgrade package yet. You can try flash an older global version rom, but with the risk of brick your phone. Through I think worst could happen is you have to wipe your phone.
You can find download link for global rom in this thread.
Q: How do I switch to Europe or Global OS?
A: Wait for the new version, download the #Full package and Local Update it. If you have Magisk installed, you can try to Local Update after entering the following command (need ROOT access).
resetprop ro.build.date.utc 1400000000

That's my case too.
I'm also in the 11.2.5.5 Indian SW.
So it's better to wait for a Global 11.2.5.5 or newer to flash over it? Right? It's not necessary to erase all data?
Does someone know what are the benefits from Global over the Indian? It seems that OnePlus is giving more attention to Indian market (updates, features, etc)

From what I can tell, there is no discernable difference in the firmware other than bloat directed at the Indian market. I'm also on LE2120 in the U.S. running the DA firmware. Everything on my device is fully functional as far as WiFi, 5G connectivity and all that. I debloated all the Indian specific bloat (red cable club, cloud storage and the like, especially since it doesn't work here in the States). I expect you can flash other regions firmware without issue or data loss so long as the other regions firmware is "newer" than what you're already on, otherwise it simply won't let you using local upgrade.
I'm also on LE2120 in the UAE running out of box coloros, then downgraded to the DA firmware, today I have updated to Global 11.2.5.5 . Everything on my device is fully functional except 5G (ETISALAT) and Invalid VIP NV's:2500 at every restart

is the nv 2500, the verification in about phone page in system setting and the missing 5g all related upon cross flashing the color os to oxygen os?

did you check the verification area under the "about phone" page in system settings. there are no regulatory labels there

Question How to change my OP9 pro indian firmware to european ?

So my OP9 pro is a Chinese variant that came preloaded with oxygen OS out of the box but Indian variant, the phone works well except for one problem, it doesn't support 5G where i am ( Dubai using etisalat) while my wife's 9 pro came preloaded with the european firmware and 5G works fine on the same network, is there a way to switch to the latest european build ( C.62) and will i need to do a factory reset ?
thanks in advance.

I've seen these before, the phone does support the frequencies of my carrier, but for some reason it wont connect to 5G at all.

Global rom has 5G I don't think EU rom does. I could be wrong though. I had to switch to Global when I converted before to get 5G. But maybe it has changed since then.

Of course EU ROMs HAVE 5G.
