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

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

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

If you are having the cannot update issue and have the global variant of the OP9 Pro, you probably had flashed the EU (or other / wrong software version) boot.img.
If your software version is anything other than 11.2, (including 11.2.1.1) you will need to get a boot.img from someone else or pull it from OnePlus website for your software version (once OnePlus gets to adding the OnePlus 9 Pro to their website) for that OOS Software version and can still use the following, but replace steps 3 and 6 with your .img file name.
If your software version is 11.2 and you have a global model, the stock boot.img for global 11.2 is attached.
Simply plug your phone into the computer with USB debugging enabled and trust the computer for the adb connection. Open up command prompt window and make sure you cd [platform tools \ adb directory], a.k.a. change the command prompt directory to your platform tools / adb folder.
Type in the command prompt window: adb reboot bootloader
Once in bootloader, type: fastboot boot 11.2_global_OP9Pro_boot.img
Verify the phone boots
If it boots fine, follow step 2 again then...
Once in bootloader, type: fastboot flash boot 11.2_global_OP9Pro_boot.img
You will now be unrooted and able to update your OP9 Pro to the latest software version, which is currently (as of 4/2/21) 11.2.2.2.
All credit goes to purpleman2k for providing the boot image on 11.2 Global and other diagnosing help.

Prior to this it would download the OTA update but I would have error installing. I'm not unable to download it.
Do you know where the OTA is download is stored so I can manually remove it and try to download it again
do I use this if I want to get back on the global firmware? I flashed the EU to get the latest update as I couldn't get the updates due to my EU boot.img.
Also, do we patch it to get root again?

Hi all,
I've the 2120 with the OXOS 11.2.5.5.LE15DA I would flash my device whit the EU version. LE15BA.
I'ts possible flash it using the FULL 11.2.6.6.LE15BA ?
I just tried with the same version number ( 11.2.5.5.LE15BA ). but does not work becase the version number is the same.

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.

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.

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.
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.

[TMO] OOS/COS DATA FIX
TO CLARIFY THIS IS A ROOT ONLY FIX After 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...

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.

Do I still need to flash the data retention zip?

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

Got it. Out of curiosity is there a way to flash it without root?

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.

when you say flashing, are you talking about using MSM?

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.
