Flash Q roms from OOS 10.0.4 BA

Hello I want to install a Android 10 ROM but I just can't do it. I've followed instructions and tried to install crdroid, Paranoid and Pixel Experience. Everything result as a never ending boot animation or "no command" screen.
The logcat spam me with
Code:
[email protected]::IVendorF ingerprintExtensions/default
ServiceManagement: getService: Trying again for [email protected]::IVendorF ingerprintExtensions/default...
I've followed those instructions
From last OOS, reboot to fastboot, boot TWRP, flash last OOS and TWRP, reboot, do the same, reboot, format Data, reboot, flash the ROM and TWRP, reboot.
I've may added some extra reboot to be sure but it should work fine.
What did I do wrong, is this because I come from a BA version and not AA ? or 10.0.4 instead of 10.0.3 ?
I need ppl to tell me if they were able to flash a ROM coming from 10.0.4 BA please.
Thx for your support

Please someone, don't tell me I'm the only one having a European firmware...

I can confirm this too when i use EU vendor (GM1913).
I just use MSM to convert the device to International (after backing up EVERYTHING).
Using MSM->Unlocking bootloader again->Installing AOSP

Why did you not just falsh the international version in twrp instead of the eu version and then flash a custom rom of your choice. No need for the msm tool.

because you can't flash GM21AA stable on a GM21BA based rom (error 7)

Boot image for 11.1.1.1 EU

Hi, I just received the the Android 11 (2nd) upgrade, 11.1.1.1, and flashed the boot.img specified at the link below (since it seemed to be the same version AC01BA) to regain Magisk capabilities.
Now it is stuck in a bootloop and I have tried to reflash boot with the "stock" boot.img with no luck.
My last hope is that the boot-image in this latest release from OP have changed and that is what made my boot-image the wrong one.
So PLEASE, can anyone please lend me a hand and give me the boot.img for the latest OxygenOS EU release?

For anyone stuck in the same ditch as I was here is the short story:
The boot-image seemed to have changed between the original OxygenOS (Android 11) release and the latest named 11.1.1.1.
I downloaded the stock OS using the first link below, extracted the boot-image using the instructions on the second link below and got the boot-image uploaded to my Google Drive on the third link below, at your pleasure.
Magisk and SafetyNet verified.
(I used this stock OS NordOxygen_14.E.18_OTA_0180_all_2103112026_22699e750a6)

Returning to OxígenOS from LineageOS 18.1

Hi everyone,
I wanted to know how can i go back to OxigenOS from LineageOS 18.1. I have tried fastbooting an older version of the Lneage recovery, but in their wiki Is no longer available. Also, i have tried fastbooting the OxigenOS 11 OTA but i am receiving an error that saya "The installed kernel version Is higher than this one"(OxigenOS 11).
Any idea of what can i do?
Thanks!

This is not the thread to post your queries.
Ans to your question is there is a Fastboot flashable rom(flash.all bat file in it) flash that. Flashing it will give oos10 and update to oos11 from there.
[ROM][STOCK][FASTBOOT][OP6] Stock Fastboot ROMs for OnePlus 6
Things are changing with the advent of project treble and seamless updates. OnePlus will no longer release ROMs flashable via stock recovery (with twrp is possible but not recommended). The updates will be done on the slot not used for example...

Thank you, and sorry, this Is my 1st post here. About the flashable ROM, where can i find it?

Question How to convert a oneplus 9 tmobile oos12 to pixel experiencie or another rom

Hi everyone! I have a question! Does anyone know how to install a custom rom on the oneplus 9 t mobile with OOS 12? Do I have to downgrade or can I install a rom that has android 12 by default?
My version its LE2117_11_C.19

You should firstly update to the latest OOS12 update TMo gives us. After that unlock bootloader (as per the guide here on the fourms) via unlock code method (you will have to wait for TMo to send that your way as it's device specific) and then follow the instructions from the rom provider.
I'm running StagOS on my TMo OnePlus 9 without issues since their last release, before that ran Lineage, Jaguar, Nameless. As long as you are updated to latest OOS and with an unlocked bootloader, you can flash any rom on here provided you follow their instructions. If you brick your phone you can use the modified MSM tool I posted on one of my threads to un-brick and bring back to life your phone (keep a backup of your data though)

so can i follow any tutorial to install any rom if i have unlocked bootloader next to sim? since I tried once to change to global and it worked, I put a module and my cell phone and the phone bricked, with the MSM Tool I was able to recover the OOS t mobile version, but I thought I had to downgrades OOS 11 to install any rom and I never did anything again because of fear for the brick
sorry for my bad English

Yes, that's it. Basically have your phone updated to the latest OxygenOS TMobile can give you,; Have your phone SIM Unlocked AND Bootloader Unlocked and then follow all the steps the Developers of the ROM you choose give for the installation.
If any rom specifically asks for OxygenOS 11, then the same steps are applied except instead of latest OS versión, the one the Dev asks for

Then I will start the installation of some rom that I like on top of the latest update of tmobile OOS 12, do you recommend any specific one that is pixel experience or similar performance?

For example, when I go to the official lineageOS 19.1 page, it says that the compatible devices are all except mine LE2117, do I continue to install anyway?

Help: Restoring original Modem.img on KB2007? (LineageOS)

Hey, first of all thank you everybody for all the work you put in to these phones. I'm pretty new to all of this
I installed LineageOS nightly on my KB2007 and attempted to flash the global modem & Magisk module for DSDS to enable dual-sim capability (as per this guide), but something must've failed that I don't understand, because now not only does dual-sim not work, but my original sim can no longer connect to the network
In the process it didn't occur to me (because I'm an idiot) to adb pull the original modem.img for backup before replacing it
What can I do to restore the original modem so I can keep using this phone? Does anyone have a copy of the original KB2007 modem.img?
Thanks for any help you can offer
Note: I've also tried factory resets, and re-flashing LineageOS, to no avail

In this reply I'm assuming your using LineageOS 19 (Android 12).
Seeing as the guide you followed is from 2021 the modem firmware you flashed is most likely for android 11.
And as such likely incompatible with android 12 firmware.
The Magisk module from the guide might also be incompatible with LineageOS 19.
If you want at least one sim to work i recommend reflashing the firmware.
NOTE: When updating firmware follow the guide/thread to the point. This phone was released with both DDR4 and DDR5 RAM. Flashing firmware for the wrong DDR type will brick your phone.
You can update your firmware by doing one of the following:
1. Flashing a firmware zip from this xda thread: (thread)
I recommend using KB2003(EU) android 12 firmware as that one is recommended by the LineageOS maintainer.
Make sure you flash android 12 firmware the .zip name should end with (12.0-ddr).
2. Using LineageOS firmware update guide: (guide).
You can get full stock rom from here: (stock rom). Since the OnePlus site still hasn't been updated with the android 12 ROM. I recommend using KB2003 firmware since it's recommended by the LineageOS maintainer.
3. You can also try to only flash the modem.img from one of the above options and see if that works.
(For the first option its inside the .zip file)
Alternatively if you require dual-sim you can go back to the stock rom using the MSM-tool.

Using this will wipe your phone and relock your bootloader.

Thank you so much for your reply! You're a life-saver
In case anyone gets here by Google and was as stupid as me:
- First I went against the guidelines and tried flashing the kb2005 firmware ("global firmware means it'll have dual sim right?"), when I rebooted I couldn't use the touchscreen
- Rebooting again (volume up + power), interrupting it to go to fastboot mode, and flashing the kb2003 firmware fixed that, but still left me with no connection (still don't know why)
- Using the MSM tool to restore the stock T-mobile ROM fixed everything
- After that, I re-unlocked the bootloader and re-installed LineageOS as per the guide and now everything's just fine & working in Lineage. I still don't have dual-sim capability, but it's better to not have a $300 brick and just deal with using only one sim
