However I don't have 5g as an option in network just 4g and although i have the volte switch in settings it doesn't do anything
I'd appreciate any help
you have to use oxygen updater and in settings set your device as OnePlus 9 Pro. not EU or India. just the regular one. Then download the latest OTA for that one. the issue is EU for whatever reason took 5G off that ROM. flashing the global version fixes it. You may have to msm first if you flashed the latest OTA already

I cannot find anything clear enough to take the risk on without a first handers confirmation or lead. I'm already rooted but, the apps I want to use most are not compatible with my version.
Use TMO to EU MSM and then download the update or use oxygen updater for global and flash that via local upgrade. You should then be on 11.2.8.8 global if you use that update.
You'll also need to flash your TMO modem or you won't have service. You'll need to do that after every OTA.
If you go to the main op9p forum and look at the how to section you should find everything you need. The TMO to EU MSM tool, the repo of updates, and the how to backup your TMO modem.
Thanks much! I appreciate the information.
My brand new OnePlus 9 Pro NA/Global was bought straight from OnePlus website. Is it possible to do LineageOS and also put the T-Mobile US modem so I can use all the T-Mo frequencies? If so, what order should I do things? Thanks in advance.

Does this actually do anything for the global version being used on TMobile? I know it helps for EU or TMobile to EU conversions.

Hi,
using a complete stock Redmi Note 8 Pro. Installed with FW 12.0.5.0 (A10) Stable. All stock nothing changed or unlocked.
It is not possible to update this phone to any newer FW Release
Tried all existing newer Releases (12.5.2.0, 12.5.3.0, .... 12.5.7.0). It is EU Model.
Error Message:
Sorry, flash to this stable Version is not allowed.
Miui Version: MIUI Global 12.0.6 Stable - 12.0.6.0 (QGGEUXM)
Found some other People with the same issue on german Forum, but nobody found a solution for this. Maybe here is someone who can help.
Just unlock bootloader and lock it with newer version if you want...
And there're some tricks on YouTube that can flash recovery file with that updater. Try to find it
Hello,
My lisa came with 12.5.5 out of the box. OTA offers direct to 13.0.2. Is there anyway I can upgrade to 12.5.9 ? I don't want to upgrade to A12 atm, or anytime soon really.
Indian firware if that matters.
I see xiaomi.eu has a version of 12.5.9 which is no longer updated, but lisa isn't listed on the compatible device list.
Thanks

First of all, some basics (not sure are you aware of):
1) If your phone came with Indian, you can update but only to Indian firmware without unlocking your Bootloader:
Install MIUI Recovery ROM using Stock Recovery and Updater App
Has your Xiaomi phone received a new MIUI update? Then follow this guide to easily install MIUI Recovery ROM using stock recovery and Updater app on Xiaomi devices. Any smartphone user prefers getting…
www.thecustomdroid.com
In that case you will need to download the so-called Recovery or ZIP stock firmware and use the installation as above
2) For anything else, like switching from Indian to Global or EEA (or to Russian or Chinese) - they are all stock ROMs, or switching to Xiaomi.eu - that is not stock ROM, or any other custom (ie, not stock) ROM, you would first have to unlock Bootloader
AFAIK, Xiaomi.eu has no 12.5 for Lisa, only 13.0 - hence not applicable if you insist on 12.5
To switch from Indian to Global or EEA (still stock ROMs), you will need the unlocked Bootloader, the so-called Fastboot or TGZ firmware (and MiFlash tool):
How to Flash Fastboot ROMs on Xiaomi? - xiaomiui
If you are a Xiaomi user and have installed custom ROMs on your device, then you might be wondering how to flash fastboot ROMs on Xiaomi devices. This article
xiaomiui.net
---
I don't know where do you see 12.5.9 for Lisa - I had 12.5.8 EEA) , but there should be not much difference
Anyway, install the following app and you can check which versions are available for Lisa (for stock Global, EEA, Indian, etc) or custom Xiaomi.eu:
MIUI Downloader - Apps on Google Play
MIUI upgrade app for Mi users.
play.google.com
It shows the Latest but click on Older and you will see all the previously released (stable) versions.
Btw, under Indian, I don't find 12.5.9, neither under Global or EEA (under Global there are eg 12.5.11 and 12.5.14)
From the app, you can also choose and download Recovery (zip) or Fastboot (tgz) stock ROM for the wanted version - depending on your flashing method as above
thank you very much. I did request to unlock the bootloader in the mi unlock app, but all the custom A11 roms stopped development or moved onto A12, so I didn't see much point in unlocking bootloader.
as i understand, if i am on the indian firmware, i can flash the indian rom without BL unlock. but if BL is unlocked, do i need to switch firmware as well to install say the Global ROM ?
about 12.5.9, i mistook it as the last version before they moved to 13. sorry about that.

When you unlock Bootloader it does not prevent you to update India ROM by stock Recovery method
It just gives you the additional option to switch eg to Global by flashing Fastboot/tgz ROM
Its like, you can always go by foot, but if you have a car, you have the additional option to go by car
Please take your time, Google, read to acquire further knowledge and know-how.
There are tons of guides here on XDA, on the Net, Google videos, etc
[Posting here since this forum seem a bit more active than OP9 forum.]
Hi guy. What are the steps I can follow to convert my Indian(LE2111) OP9 with Indian Oxygen OS to EU variant?
Wanted to get away from the bloatware in Indian ROM & EU variant seems to support dual SIM. Also want the US version of Gpay, etc.
I downloaded Oxygen Updater , changed device to OP9(EU) & downloaded the full OTA ROM. When I try to "Local Install " on Settings page it says "verification failed".
I also downloaded the LocalUpdater apk, which also fails.
I haven't unlocked the bootloader or rooted the device
What steps am I missing?
I have the same needs but for my OnePlus 9 Pro.

Thanks for responding. It's seeming like the process has changed a lot since the last time I flashed ROMs back in OnePlus One days. lol
I'm currently on LE2111(Indian ROM) C60 on Indian variant OP9(dual sim, no wireless charging). I want to move over to EU ROM.
So are the steps:
1. Downgrade to android 11 using MSM Indian tool.
2. Flash android 11 using MSM EU tool
3. Update from OTA/Oxygen Updater.
??

Or you could do it in simpler way: after downgrading to A11 with MSM Indian tool use Oxygen Updater and select EU device, in the app’s settings: “Stable (full)” update method and enable advanced mode.
This will let you download the latest EU full ZIP, which you can install via the system’s built-in “local install” feature or the separate local upgrade APK https://oxygenos.oneplus.net/OPLocalUpdate_For_Android12.apk

Tried it. Got to A11 using Indian MSM. The local upgrade option still fails with the EU full zip saying "System update installation failed"

Then go with your bullets 1. - 3.
I did that and it worked.
I have proposed a modification based on the input I've got from someone else but apparently it doesn't work.
