Can NOT install UT Redmi note 9 pro "exit code 256"

@smobilesoft If you are using the MiFlash tool, it means you are using Windows.
This is what you require to do:
-
make sure the bootloader is unlocked. You have to use the MiFlash tool to do this. Without doing this you can never down grade or upgrade your ROM to the required Android ROM or install Ubuntu Touch.
You have to use the Rom @Vlad-Nirky mentioned - why you may ask? The person who ported UT to the device used this to ensure the vendor BLOBs (drivers) would work so everything functions and other technical reasons. -
If you relock the bootloader it can brick your device or you may have to go through Xiaomi's ridiculous procedure to unlock it again. It means you cannot install UT or another Android ROM.
-
The fastboot method to get the required ROM onto the device is by far the easiest way. Again, I reiterate, the bootloader must be unlocked. You must boot the device to fastboot mode, then connect it to the PC. Open a terminal in the unzipped ROM folder (that @Vlad-Nirky mentioned) and being Windows, run the command ./flash_all.bat exactly as that. Then sit back and let it do it's thing, it will take some time before it reboots.
-
Once it reboots into Android, set Android up, enable Developer Options and USB debugging. Start the UT installer, attach to the PC and follow the on-screen instructions, ensuring all boxes are ticked as it is an initial install.
-
When installing UT only interact with the device when you have to. The reboot into fastbootd can take some time.
Other considerations - make sure you have drivers installed for the device (you should have). Install the latest version of Android Platform tools. Try installer version 0.10.0. Windows sometimes has an issue with fastbootd (which is not regular fastboot).

when you say "some time" do you mean 30 minutes?
because that how long I let there doing nothing -
@smobilesoft No, 30 minutes is awy too long. It should take no more than 5 minutes. If it does not stop the process and reboot the phone to fastboot. Open a terminal in your fastboot folder and run
./fastboot reboot fastbootIf it boots into fastbootd, good. If it does not, there is an issue somewhere.

AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!!!!!!????!!!
W.T.FlagI installed UBport Installer in my dev rig/linux and IT WORKED!!!!!!!!!!!!
$*&% windows
After about 20 hours, maybe more, of trying, it just came to: "just don't use windows dude"
The windows installer do not recognize the phone when it is in fastbootd mode, so it stops the process.
Thanks guys @MrT10001 @Vlad-Nirky for the help and support

Probably missing drivers.

@smobilesoft
To be used, you must enable usb debuging, plug the device on the windows PC, run adb.exe devices.
If the devices is not shown, you can install the usb-drivers.

Well...... when my phone was in bootloader, the adb was finding it without any issues. Only when it was on fastbootd mode could not recognize it.By the way, the global rom was not working, since I live in Greece, and I can verify that I re-install UT with the following Android version for European users:
V12.0.1.0.QJZEUXM -
The guy from the reddit forum answer with the following, just in case it will help someone:
*Hi, if you give me more information about your current situation I might be able to assist more.
Basically my issue was that the installer made the system partition too small for all the files and updates and it fizzled out while trying to complete. So I just manually increased the partition size.
To do that you need to boot the phone in fastbootd (not the bunny fastboot/bootloader). If you are in UBports recovery, just select Advanced>fastboot, if not use fastboot reboot fastboot (I assume you have platform-tools installed, if you have gotten this far, you need them for next step).
First remove these two partition if present to free space (UT doesn't need them):
sudo fastboot delete-logical-partition product
sudo fastboot delete-logical-partition system_extThen run sudo fastboot resize-logical-partition system 3900000000 (3.9GB worked for me). If you get "size too big" try a smaller number.
Then go back to bootloader/fastboot (bunny) and run the UBports installer again. Make sure to select wipe data and bootstrap.*

Well...
I have the same phone.
I am not a porter and I apologize to them (or invite them to correct me) for the shortcuts used.
I have unlocked it, install the needed ROM to be compatible with UT port.
The UT port interacts with an abstraction layer called Halium.
There is a version of Halium for each version of Android 9, 10, 11, 12, etc.
Halium interacts with the low-level Android drivers that are left in place when UT is installed and Android is replaced.
The port therefore expects to have very specific drivers (those of the recommended version of Android).
Each ROM contains a number of partitions that are either left in place, replaced, or modified.
Altering these partitions (or using a non-compliant ROM that has other partitions) can therefore result in a system that cannot receive UT or anything else at all.
You can experiment, and it may be beneficial to you and to others who are in the same situation or not.
When the device is unlocked and the ROM joyeuse_global_images_V12.0.3.0.QJZMIXM is in place, installer can resize the needed partitions via
