So I have a OnePlus 9 Pro 5g T-Mobile (USA) and I was able to successfully put in the official Global Android 11 build in it (11.2.10.10.LE15AA).
I had cell and data service when I using the global android 11 build, however when I upgrade the phone to android 12 I lose all service, both data and cell service (sim card is not even being detected, there are 2 empty sim slots showing in the notification bar).
What do I do next? Is there a step by step guide? I saw many posts scattered across different threads trying to resolve this issue, but it was very hard to follow.
Note: I have backed up my original T-Mobile MODEMST1/2 AND PERSIST PARTITION images before I changed my ROM.
I have tried the following method, which resulted in a brick.
Method 1 (DOES NOT WORK-BRICK)
1. Tried to convert to the EU MSM but it didnt work.
2. converted my phone to India MSM and it worked
3. Under the India MSM i did a local upgrade to the Global Android 11 build in it (11.2.10.10.LE15AA).
4. flashed the t-mobile modem
fastboot flash modem_a NON-HLOS.bin
fastboot flash modem_b NON-HLOS.bin
5. Brick
Before jumping to Android 12 you needed to flash the data retention zip. That'll tell the system you are on 1 sim and not 2.

Adb sideload it or flash it through a custom Rom recovery
When updating Global from android 11 to android 12, DONT, and i reapeat, DONT update with the incremental update or you will lose data. You MUST use the FULL update through the oneplus Oxygen Updater from the play store, and chose the full update, and you will keep data.

I didnt, but maybe i got lucky. But if you do, it has to be flashed with MAGISK . So you have to be rooted.

Based on the instruction, it said it was a root only fix. I may be wrong, but thats what i remembered.
I would highly recommend simply updating as far as you can via T-Mobile, flashing C.62 EU firmware via https://www.mediafire.com/folder/sxdpvifk83q9g/OnePlus_Firmware_Updates#p36biy56icbc4 and then installing your custom ROM.

No, updating it all the way through to the latest firmware. If you have a T-Mobile version I recommend flashing the data retention zip.. I've had zero luck converting over to a custom Rom and Global without it. I'm currently running Pixel Experience at the moment with spark kernel.

Let me get his straight. Are you that I should:
step 1: go back to TMobile stock rom
Step 2: update the T-Mobile stock rom as much as you can
Step 3: flash the data retention with root (magisk is the best way)
Step 4: flash c.62 EU firmware. How do you do this? With msm?

Go back to stock T-Mobile firmware and update it all the way to the latest firmware which is C.62, flash the data retention zip through magisk and then you can go ahead with a custom Rom of your choice.

In that case do the stock T-Mobile firmware, update your phone to 11.2.10.10 (I believe is the last update before A12) flash the Data retention zip, download Oxygen Updater application and download then install the Global version from there.

In that case you need the Tmo-EU msm and then find the 11.2.9.9AA ROM to install through the updater.

Good Day all,
I was wondering, is it possible to revert to the stock recovery after installing the Global ROM on the mi mix 3 China Version?
Reason I am wondering is because when I/We receive a OTA update from Xiaomi while using the Global ROM, will the phone be able to update or will it just freak out on me/us and die?
Currently I am waiting for my Bootloader to be unlocked (ETA 70HRS), I have all files necessary files downloaded (TWRP, Global ROM, Magisk v17.1)
Help/Advice would be appreciated :good:
Kind Regards

I find you very helpful in the forum and I would like to ask you few questions, I am thinking about buying the device but only chinese version is available here and I cant wait for the global to arrive
my questions are:
1- global version only released with 6GB RAM , if I got chinese version with 8GB , will it be able to run the global ROM ?
2- I have never flashed a ROM before , but I have strong knowledge in linux and command lines, will this be a hard task for me to do ? is it risky to brick the device ?
3- After flashing the Global ROM , will I receive official OTA updates directly from xaiomi without any problems ?

1. Yes no problem, I'm on 8GB model and worked fine
2. Really hard to hard brick, soft brick possible but easily fixable via fastboot to flash new system, boot etc
3. I believe so, not tested as there isn't a 2nd global update out?

You'd have to use the Xiaomi EU rom with or without magisk as the global ROM has a CTS mismatch so won't pass safety net.

No, flashing the ROM will keep TWRP installed as it's a custom miui ROM.
OTA works and will automatically flash the update via TWRP for you.

Just a quick update for you all that I have successfully, unlocked the Bootloader and installed the ROM.
Just a quick note to mention that after you do:
fastboot flash recovery TWRP_perseus.img
DO NOT put in the command:
fastboot boot TWRP_perseus.img
After flashing TWRP just take your phone (either connected or disconnected from PC) and hold vol up and power. It will reboot in TWRP.
I tried rebooting into the recovery using the above command line and it just rebooted into MIUI Recovery.
Hope this helps :good:

You will need to wait till next update and flash a newer rom I'm affraid.
You could wipe everything in recovery and then use the relevant fastboot rom to go to the BA version. I did that and went from AA to BA version on 1903.

Not sure..
I think that there may be some small hardware differences?
Read all the relevant threads first.
If it's the same hardware then you should be able to wipe in recovery and then use the relevant fastboot rom.

Hello,
Yes you can flash full OTA of 11.2.6.6LE15BA without any problem without losing anything through local upgrade.
Or you can do what i did, download a downgrade ota file. In my case i was in 11.2.5.5LE15DA and downloaded downgrade OTA of 11.2.5.5LE15BA and flashed again through local upgrade, but since this was a "downgrade" it wipes all data. I didnt mind the wiping since i couldnt wait for the new update for too long.
How to downgrade the current version?

No need to be rooted. You go to the Downgrade zips links and download whichever variant you want of the 11.2.5.5. Then through Settings-System updates- Local upgrade, pick the downgraded zip you downloaded. It will promt you that you are Downgrading and it will wipe data, and after you confirm it and install it, phone reboots into recovery wipes data, reboots to android setup.
EDIT: use downgrade apk to 11 and go to EU12 now, will report have any issue later.

Hi, I'm using china phone and flash to global 12 beta, now i want to upgrade to eu stable version, i already download the eu rom and put on root directory, but i can't find the "local upgrade" inside update menu.
so i try to boot to fastboot mode and flash the zip file, after boot in to recovery mode, the "advance" option replace with "reboot" which not same as photo i saw over internet, so total 3 option there "wipe" "reboot" and "power off".
the question is how to flash the global 12 beta to eu stable rom in the best way. thx!

Nope. Everything went swell. Still have service, can use 5G, etc.
TO CLARIFY THIS IS A ROOT ONLY FIXAfter gaining root install given module.
Data is now retained. Even after reboot(s).
No empty slot or waiting.
Issue is TMO variant is showing multi sim.
So props were added to make it like a conversion to single sim....
Yes module works for both models.
Install & enjoy
Extract and pull it apart if interested .
Please give amazing thanks
to @twinnfamous for building module & bringing this data/sim nightmare to an end
Hi,
This is working great, I have flashed and rebooted multiple times with no signal loss, great work, thanks for this.
Now that Tmo has a new update out, will this need to be flash when I update to the new Tmo modem?

I guarantee 9.9 is not the fix
Yes, will have to, until Tmo A12 hopefully fixes it. But don't get your hopes up
I was able to successfully keep 5g mobile data on Android 12 using your module.
Thanks a ton.
I had also followed the other guide for data retention and that works great until the ob1 is installed, then your tool was needed to bring the modem back that was retained by his process.
But after combining the two guides and being successful so far, do you think I'd be able to take the latest c44 update, reflash your module and have my 5g return? Or are the stables garunteed to break it.?
After updating c44 via update, then installing module data_fix? Should be fine. Honestly prop is so simple it should always work

damn updated to c44 and flashed your fix, but it only gave me 4g, and h+.
Flashing the global variant for 2125 fixed the issue

Check Network settings
And check phone info using dialer command and switch "preferred networks" see if that helps. Otherwise should be no issue ...

I've been trying all day to do this, twrp won't mount anything, with or without password it won't decrypt and the android recovery is useless. I am not trying to manually flash each item from the payload.

Have you factory reset after you updated to a12 ? If so that's why TWRP won't see internal storage. Did you try to sideload the zip? I've used adb sideload to flash zips Everytime I screwed the phone up
