[Firmware] POCO X3 NFC [surya/karna] [Auto updated!] - Xiaomi Poco X3 NFC ROMs, Kernels, Recoveries, & Ot

Xiaomi custom users face a problem with firmware updates. As there are many devices with no one to provide the newest firmware update every single release, and developers who provide updates to devices may forget or be busy sometimes, so releases are provided later. Here comes Xiaomi Firmware Updater project:

What is Xiaomi Firmware Updater?
A set of various scripts that automatically generates Xiaomi firmware flashable zip files for every MIUI new update! My scripts download MIUI official ROMs, both Developer and Stable, Global, EEA, India, and China, extract firmware either from the firmware-update folder or from update payload, generate firmware flashable zip with auto-written "updater-script", and uploads them automatically to multiple servers. These scripts are completely automated, running on a Linux server every X hours.
Notes:
Firmware filenames for this device are in the following manner:
fw_surya_miui_SURYAGlobal_*.zip is POCO X3 NFC (surya) Global firmware.
fw_surya_miui_SURYAEEAGlobal_*.zip is POCO X3 NFC (surya) EEA Global firmware.
fw_surya_miui_SURYAINGlobal_*.zip is POCO X3 NFC (surya) India Global firmware.

Frequently Asked Questions:
What is firmware? Is it a full ROM or OTA package?
Firmware is not a ROM nor OTA Package, it's a set of low-level drivers which helps the operating system do whatever it wants to do. It includes various things like Modem, Bluetooth, Bootloader, DSP and etc.
Why should I update the Firmware?
Firmware is provided from Xiaomi directly, and there are no sources for it to let developers build and edit it on their own like custom ROMs, so if you want to keep your device up to date always update your firmware!
Do I need to update the Firmware If I'm an MIUI official or a custom ROM user?
No, MIUI ROMs contain the firmware-update package which I extract and provide here.
What are the supported devices?
All Snapdragon and MTK devices including China-only devices.

How to update the firmware?
1- Download the package you want to flash. IT MUST BE NAMED WITH THE SAME CODENAME OF YOUR DEVICE.

What's the difference between QJGEUXM (12.0.8) & RJGEUXM (12.0.6) of the global version?

Welcome. Unfortunately, the is no straight way to tell the difference between firmware versions. You can see if something got updated by checking the size or hash of old and new files. Another easy to notice clue is the baseband version of the modem that will be changed in about device screen after flashing.

I agree. I have been with XDA over 3 years an it says 'senior member' for me too.
I am a forklift driver with minimal computer skills who likes to dabble lol.
I cannot even code lol. Let alone write roms lol.

Interesting post, thank you.
My Poco X3 NFC is running on miui_V12.0.8.0.QJGEUXM. As you will well know, this is based on Android 10. Looking for Android 11, the firmware to install is the following: miui_SURYAEEAGlobal_V12.0.6.0.RJGEUXM_246b1aa34f_11.0.zip
But if I try to do this via Updater, it simply reinstalls the first mentioned. I don´t have a clue on how to do my device a favor by updating it. Could you, or anyone for that matter, give me a clue?
Thanks in advance.

First, this thread is for custom ROMs users. Please read the FAQ in the first post.
V12.0.6.0.RJGEUXM update is not released as full public update as for now, so you can't install it using updater.

I have the global CG. Will flashing the Android 11 firmware from the Europe region work for my device or will it cause problems?
