[Firmware] Xiaomi Redmi 9 / Redmi 9 Prime [lancelot] [Auto updated!] - Redmi 9 / Poco M2 ROMs/Kernels/Recoveries/Dev.

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_lancelot_miui_LANCELOT_*.zip is Redmi 9 (lancelot) China firmware.
fw_lancelot_miui_LANCELOTGlobal_*.zip is Redmi 9 (lancelot) Global firmware.
fw_lancelot_miui_LANCELOTEEAGlobal_*.zip is Redmi 9 (lancelot) EEA Global firmware.
fw_lancelot_miui_LANCELOTINGlobal_*.zip is Redmi 9 Prime (lancelot) India Global firmware.
Downloads​You can get updates always from various mirrors available on the website:
Latest Firmware
Firmware Archive
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.
Check the full devices list here
How to update the firmware?
1- Download the package you want to flash. IT MUST BE NAMED WITH THE SAME CODENAME OF YOUR DEVICE.
2- Flash it using TWRP or any custom recovery. There's no need to wipe/format anything before or after the installation.
How to check the updated firmware?
Usually, the modem gets updated with newer firmware, you can check it in Settings > About > Baseband.

Look the image...it is the updater-script text view...
You can sec that it patch dynamic partition and it must not right ..if anyone flash it he lost system, vendor and product...and must be his device stuck...
Look dynamic-partition-op-list in text view..
So you must edit this (updater-script) file... And delete 12-29 line to avoid this problem...
Tnx for understanding....

---

So, someone have any Idea how to repair this problem ? I can still access the TWRP, but it doesn't matter what I try to flash, it always end with "failed to mount /Vendor (invalid argument)"
It's like the /Vendor partition was deleted

---

Just look above

---

So, if anyone has the same problem, I"ll just write down here what I did to solve it.
Basically, messing with a bad flash of the firmware will mess up some partitions, and no matter what you try to flash from recovery, it won't work because the recovery software cannot find the /vendor partition.
You have to flash through fastboot a stock ROM and then redo everything, aka install TWRP again, a ROM and root.
The thing is, a tons of links claim to be "fastboot stock ROM" but when you try to flash them with Mi flash tool or whatever they never find the right batch file, and I spend hours trying to figure out what batch file and what stock ROM I need.
So here how I will save your time : Download this :
Xiaomi Fastboot Tools
You may need to install some JAVA stuff and I don't quite remember which version of it, but when it works, it's the easiest tool ever. It will give you a link for a (real) stock ROM with all the images you need depending of your device (automatically detected if you are not quite sure) and flash it for you on the bootloader

Thanks for reporting!
I have updated Flashable Firmware Creator tool. Newer firmware files will exclude dynamic_partitions_op_list and fw+vendor packages will have a modified version of dynamic_partitions_op_list with update vendor line only.
I will re-upload all recent versions of released firmware files.

Yeah boom it works if you do it before but boom it doesn't work if it has already messed up my partitions. As I said I wasn't able to flash anything at all that looked for /vendor (couldn't even wipe dalvik and cache)

Tnx a lot bro...i am so happy..
Need 4 option...
1.only vendor
2.only fw
3.fw+vendor
4.fw less rom
Because many people want just updated vendor not to update fw

I have installed it. However, I can't add gaaps. The gaaps installer works. I was not able to start Google Play Store or login to google account.
