Hey all,
I just got my 9 Pro. Unfortunately I had to get it thru T-Mobile. That last couple OnePlus devices I have always converted them to the Global firmware.
This go around I am wondering if it is worth it. Are there any benefits aside from de-bloating?
Looking for some opinions to help me make my decision before I reset and go thru the process of setting up my phone again.
And yes, the SIM is unlocked already, and I have my unlock token to unlock my bootloader.

TMobile 9 Pro user here. Had the 9 as well. Both converted. Quick question without seeming cocky, you mentioned you converted your old OP devices in the past, why did you convert them?

To de-bloat.
But if that's the only positive this go around then it's probably not worth me doing since I have been de-bloating more with ADB lately. But if others have any input on other benefits then I may do it again.
Well my opinion, updates. I'm still on OOS11 but that's by choice. For one,even though I can't change the stock oos bootanimation, it's still better than T-Mobile stock. Second, a lot of support with custom roms, kernels, and mods don't give support to people who are on TMobile firmware for some reason (don't ask, don't know lol).
Third, it's a lot easier to cross-flash firmwares and downgrade, especially with an unlocked bootloader. I was able to go from OOS12 beta to stable, then to custom w/kernel, then to COS 12.1, then back to OOS11 with one single MSM. To me, it just seems all around easier. There's more reasons, I'm just in lunch so I figured give you my two cents.
Right now my setup is OOS 11.2.10.10_DA with latest alpha Magisk using the latest Shamiko with Zygisk with Hide off, fully passing SafetyNet. Arter R12 with latest TWRP.

I appreciate you input, and that did help me make a decision.
What was your method to convert your T-Mobile 9 Pro? Because every method I tried ended up bricking my phone. It would always be when I had to flash the modem when it would brick. Followed the guide on here and other sites multiple time and always the same.
Guess it's not like old OnePlus where we can just flash different firmware willy nilly.

So I spent a week figuring this out. I realized a few days ago that I mistakenly flashed the Indian firmware for the OnePlus 9 PRO. I have the regular 9. I tried to flash every other msm I could find and download. Nothing seems to work except the Indian OnePlus 9 PRO msm... Problem is, the camera, flash and fingerprint scanner didn't work. I was able to toggle the unlock oem button by running an adb command line then I did oem unlock in fastboot. After that, I followed the instructions for installing StagOs 12.1, which involves installing lineage recovery then flashed the rom. Everything works flawlessly! Love this rom.

Hello Redmi Note 5/Pro users!
I was browsing the forum looking for the available custom ROMs for our device and decided that I wanted to try Pixel Experience, so I started looking through guides to unlock BL, flash twrp and then flash a custom ROM. Thing is, I'm a little bit confused.
First of all, I've read the post about how ARB works, and I still can't find the answer that I'm looking for, or probably I still can't understand how ARB works at all. Let's say I unlock BL, boot twrp, flash twrp, and then I flash a ROM like Pixel Experience. What is the safest way to get back to MIUI? As of my understanding I will only brick my phone IF I flash an older version of MIUI, thing is, what is "older" exactly? I'm sitting on MIUI 10 V10.2.2.0.OEIMIXM right now, If I wanted to flash MIUI again should I flash any newer build (when it comes out) to the one I'm sitting now (or the same)? Also, what precautions should I take when doing so? (I've read someting about encryption that I don't understand at all).
Secondly, does this guide still work for the current MIUI version and ARB version (I'm on 4)? I've read some comments saying that the part of flashing twrp is not updated and others saying that everything still works perfectly, can someone confirm this please?
That's it for now, thanks in advance for your patience and let's keep this community awesome!

1. More info abt arb 4 and 3: https://en.miui.com/thread-2340434-1-1.html
2. Basically you can flash any rom with arb 4 (not necessary newer than your current rom version)
3. Yes, this guide still works but you'll need to enter fastboot flash antirbpass dummy.img on fastboot before flashing twrp, just google whyred dummy.img and you'll find it.

Hello,
I received my oneplus 9 pro (global) the other day, and it's been working great. I rooted it no problem with a boot image I found on xda, and patched it using magisk manager. However, whenever I try to download the newest update, it fails every time. The first time it says that it's paused, and that it will continue whenever you press resume. I press resume, and then it says a problem occurred.
I tried to delete the .OTA folder, but it's no where to be found. I also tried to factory reset, as well as flashing the unpatched boot image, but it did not work.
Here's the link as to where I found the global boot image

As far as I know, you can't take an OTA (incremental update) with either an unlocked bootloader or root. Not sure which of these is the actual culprit. I'm on the Global version (AA) and just flashed the full BA update. All is working well, only downside is that Dolby Atmos doesn't have the equalizer on the EU (BA) version. Everything else including 5G is working as it should, just like on previous versions of the OnePlus devices I've had (3T, 5, 6T, 7Pro and 8Pro).

I'm from the US, so I don't know if the network band will be the same, if so as good on the BA version.
If anything, i'll just wait for the official Global release on their website. It's just infuriating to see something that annoys me get fixed, such as the white navigation bar in split screen, and not being able to update.

You may not want to hold your breath on that one. For whatever reason, oneplus does not release full OTA zips for AA half the time. (WTF ONEPLUS). Because of this, I long since started flashing BA over my global phone. As the gentleman said up above, it works absolutely perfectly.

can I just flash the BA version on top of my current rom (AA) and not lose anything? I just got done reinstalling everything, and it was a pain. I don't want to do this a 3rd time, if I can avoid it.
I never had any issues with rooting/being unlocked and updating on my previous OnePlus phones... this is a new one for me.
On 8t I had to use EU..google is who releases OTAs for all variants except EU, which is still directly from oneplus. Rooting broke OTAs for me as well on any other rom besides EU...also I have 9pro, which I local updated to EU zip b4 flashing magisk_boot.img and I already received new update since rooting and all is good.
I just flashed BA on top on my current rom via system update (you have to click the cog wheel top right and put the OTA zip on your root directory)
Nothing changed and the navigation bar in split screen is indeed fixed, meaning this is the latest version.
Thanks again for letting me know about this!

I'd be careful about flashing an international build for a global variant as EU regulations could be stricter, and most times are, with respect to signal strength, emissions, and other factors. Might work fine now, but there are different variants for a reason and one specific to the EU for a reason (laws are vastly different).

To unroot, go into magisk and click uninstall. Do know that I have tried this already and system update still won't go through. It appears it's being picky about the bootloader being unlocked I think. This is weird because on my OnePlus 7 pro, I did not have this issue and all I had to do was go to Magisk, uninstall ---> restore images, then do the OTA, and then have Magisk install to second slot, and then I would go back to system update, allow it to reboot, and I would still be rooted.

geez, I hope we don't have to relock and unlock for every update. I guess for the time being, there's no reason to be unlocked, but when custom ROM's start rolling out, that's going to be a major headache. I wonder if/when the updates are posted on One Plus website, will the updates work, or will root/unlock still prevent it?
I really want that update as I'm reading it made the battery much better. What to do!
I'm curious. so for a brand new phone why are you guys rooting it? It is not loaded with bloat ware (at least as much as samsung fpr example.) there are no custom roms yet, and oneplus is pushing updates to fix bugs. I think I'll wait till custom roms show up and then consider rooting.

Hi
I dont have signal on my cellular now after the updating...
There is a Temporary fix until the next update ?
I have the same problem. I can't even downgrade
New version 22.0.0.0 and no signal bug. Omfg
Having trouble since open beta 1 in receiving and placing calls, crazy what 1+ is releasing
12 sounds is shaky at best
12 stable managed to brick my phone almost.
Had to use all sort of tricks to get out of Crashdump Mode. But you can get out.
Anyway. It's a mess.
I have network but the whole OS feels SO unbaked. My phone is stuck in 60hz most of the time. Apps, functionality is missing. Things we've had in OOS. It's crap, I am sorry I'm going to say it like that.
This is a DOWNGRADE.
I wonder how 1+'s forums will look like after people storm it.
Anyway. You can downgrade with MSMTool, but it will wipe your data and you start from the stock OS.
Guess you can download latest OOS11, and Local Upgrade via System Update and disable update.
That's my plan at least.
You can also try using custom roms, but I am unsure about their stability (yet).
I'm still hoping they will release 12.0.0.1 this night

How did you get into edl mode running A12?
My network doesn't work on OOS12 stable for some reason. I spent 2 days flashing different oos12 builds (eu, global, indian) to try to see if the network comes back, tried literally everything but no luck
Very disappointed. Had to come back to OOS11. Everything works perfectly, except the fact that I'm not running the latest android version on my flagship 9 Pro.
Read my post here. And back through a few others.

I was getting the same issue, but flashing a different variant of your current c.44 should do the trick.
Ex: I have a LE2127 (TMO), I converted with a11 to use LE2123(EU) software updates. When android 12 hit my phone wouldn't give me data on the 2123 update, so I had to download the LE2125(global/NA) update and flash using the the system update app that was so generously given in the following post:
Post in thread '[TMO] 9 PRO MODEM RETENTION' https://forum.xda-developers.com/t/tmo-9-pro-modem-retention.4292445/post-86328243
I don't know what software or model your phone is now, so I am NOT suggesting you switch if you are not already on 2123 or 2125. Those two are interchangeable without problem so it should be fine

Are you sure about this?? Because I flashed OOS12 by first flashing OS 11.2.8.8 through MSM tool and then updating to android 12.
Do you think flashing 11.2.9.9 will actually work, because I'll have to through the hastle of downgrading and then updating again. (As I'm running 11.2.10.10 atm)
The help is much appreciated.

Same way you would in android 11.
Make sure the phone is completely off. Hold volume up and volume down buttons, and plug it in.
Make sure you already have the msm tool fully opened and ready to click enum.
As soon as you plug it in it should say ok ok in the tool, click enum then start.
I stress that point to do it quickly because it will fail with different errors if it's not done quick enough after the device is plugged in.
Hi,
First off I'm pretty new to the Forum so I'm just starting to understand some of the existing threads posted here.
My TMO OnePlus 9 Pro was updated to Android 12 back in March and since that time I've been having several issues the primary of which is that Microsoft Intune is no longer able to validate the configuration of my device. This has locked me out of company apps on my phone for the past several months and it's a real pain.
I looked into the issue and from what I can see it seems to be a bug in oxygen OS 12 relating to Android work profile. I have heard that this bug was fixed in later versions of oxygen OS but unfortunately T-Mobile have not made any new version available since March.
I tried converting my device to T-Mobile EU using the MSM tool and, while I was initially successful I wasn't able to get the T-Mobile modem to work on Android 12. I sent reverted back to T-Mobile US using that MSM.
The way I see it I have two options.
1. Wait and/or work with T-Mobile support to get a newer Oxygen OS build pushed to my device.
2. Figure out a way to fix the modem issues I was facing after upgrading to A12 following the EU MSM conversion.
Is there a fix available for the T-Mobile modem in Android 12? Sorry if it's been answered already but I couldn't find details anywhere despite searching. I'm looking for a no-root solution since that defeats the purpose of doing this to get Intune working.

My TMo OP9P LE2127 had updated to OOS12 before I had a chance to root it. I hadn't read enough about it to worry about trying to block the update. Well, I hated OOS12 and I eventually downgraded back to Stock OOS11 and then converted it EU with the MSM tool. Currently running a rooted OOS11.2.10.10 on both slots.
Not once did I have to touch the modem and my 5G works just fine. Everything worked out of the box (aka conversion MSM). My phone is even still SIM locked. I believe others have experienced the same thing with a LE2127 that updated to the stock TMo OOS12 firmware. The modem seems to stick after that upgrade, even after downgrading it back to OOS11.
I've blocked my phone from manually checking for updates and I'm perfectly happy with my phone for the time being. That said, I have not tried updating my phone to any EU versions of OOS12 (C.48 being the latest, I think?).
So, that's my experience, but your mileage may vary.

Hi,
First off I'm pretty new to the Forum so I'm just starting to understand some of the existing threads posted here.
My TMO OnePlus 9 Pro was updated to Android 12 back in March and since that time I've been having several issues the primary of which is that Microsoft Intune is no longer able to validate the configuration of my device. This has locked me out of company apps on my phone for the past several months and it's a real pain.
I looked into the issue and from what I can see it seems to be a bug in oxygen OS 12 relating to Android work profile. I have heard that this bug was fixed in later versions of oxygen OS but unfortunately T-Mobile have not made any new version available since March.
I tried converting my device to T-Mobile EU using the MSM tool and, while I was initially successful I wasn't able to get the T-Mobile modem to work on Android 12. I sent reverted back to T-Mobile US using that MSM.
The way I see it I have two options.
1. Wait and/or work with T-Mobile support to get a newer Oxygen OS build pushed to my device.
2. Figure out a way to fix the modem issues I was facing after upgrading to A12 following the EU MSM conversion.
Is there a fix available for the T-Mobile modem in Android 12? Sorry if it's been answered already but I couldn't find details anywhere despite searching. I'm looking for a no-root solution since that defeats the purpose of doing this to get Intune working.

In order to get the modem working in A12, you have to have root and flash a Magisk module that fixes your build.prop. Unfortunately, your need to be unrooted prevents that from happening.
If you're OK with rooting temporarily, you could modify your build.prop to have "ro.vendor.oplus.radio.multisim.config=ssss" after flashing EU, then unroot afterwards by flashing stock boot.img.

Yeah, that could work. Does build.prop need to be updated after each OTA update?

Shouldn't need to be updated.
Also, you could try unlocking bootloader, rooting, modifying build.prop, unrooting, then relocking bootloader if you're ok with testing. It may/may not work. If it works, then you don't need to modify ever again, at least until a future update touches that file.
If I have no sims detected am I able to flash something to regain sim detection and data?
before I root my phone I wanted to ensure I had a good stock rom to load in the event of an issue.
I'm currently running Oxygen OS 11.2LE15AA.
I can't find this exact version and I understand the AA versions are little different than the TMO versions. I believe this is the "global" version. There are some 11.2.xxx.AA versions, but not this specific one.
I investigated getting the image directly off the phone, but it appears you either need to have a rooted phone, or possibly installing TWRP (or other) and creating a backup. Then extract the image files from the backup.
I've rooted phones in the past, the last being my oneplus 3t. things have changed a lot since then. I've been studying up and want to make sure I get this right.
I really would like to have a golden (and trusted) image to fall back on.
Any insights are appreciated.
btw. I have two 9 pro's. my le2125 (cracked screen) i'm testing on, and a brand new le2127 (11.2.44.LE5ACB) I'll root after confirming I can root and restore these. The later is the TMO version.
I was planning on the Magisk root option. Looks like you can do it now without TWRP. I just want to debloat and Xposed. Magisk looks like it might have some interesting options I'll explore. For now I just want to locate a stock rom for 11.2LE15AA.
Thanks in advance.

Apart from the MSM Tools linked by the previous poster, you have all the available stock ROMs listed HERE. Check whether you can find yours there.
Do not use the Indian MSM tool what ever you do. What 11.2.x.x version do you have....?

thx. per that link
Global devices (LE2125) with build tag LE15AA zips use Google OTA servers, thereby making it impossible to capture full OTA zips under normal circumstances but Android major updates. However, should they be obtained or be posted on support website, they will be added.
and the website only has the latest 11.2.10.10.LE15AA
guess i'm screwed on getting a golden image. This really opens a can of worms for me. LE15AA are they really that special? Is there a know good sub version. I've seen 11.2.1.1.LE15AA images out there.

It also goes on to say
LE2127 units are T-Mobile units running their own version of OxygenOS labelled LE5ACB and lack local update option in Settings --> System --> System Updates and are therefore not supported.
Which is my new replacement, so what does "not supported" mean for rooting it
This is my setup on LE2127 TMO variant. Firmware 11.2.9.9 ( I will stay on this for now because of some issues on A12), unlocked bootloader, rooted with Magisk, TWRP installed and a special script flashed which mounts partitions as R/W. I have complete control of my phone and that is what I expect when it is in fact "my phone" unlike a Galaxy phone that bootloader is unable to be unlocked..... As for a golden firmware to fallback on, are you wanting Global or TMO?
