With telnet I have see it is a mount failure.
On Telegram a man say to Put the .IMG file in data folder
I have put boot.img and ubuntu.img, but I think ubuntu.img is sufficient.

And now it work :beaming_face_with_smiling_eyes:

I can't edit my first post, so this is the UP TO DATE TUTORIAL :

How to install UB T - Ubuntu Touch - UBPorts on a Poco X3 Pro - Vayu

• Unlock bootloader
• Install TWRP or OrangeFox
• Install a global MIUI 12.5.9 with Android 11 (to be sure all is ok) http://xmfirmwareupdater.com/miui/vayu/stable/V12.5.9.0.RJUMIXM/
• Download Artefact on github : devel-flasable-focal (to see the last version is here
• Extract the zip
• Download the vendor from Droidian vayu 100 or take the last one here : Droidian git (it is the Sailfish one, and I don't find it on UBT) It is the MIUI with some fix for Linux on phone. You could try just the adaptation images, but not tested : Adaptation for Poco X3 Pro codename Vayu
• Extract the zip
• Reboot your phone in recovery
• Reboot in fastboot from recovery so it is fastbootd (Android fastboot, don't works)
• From the Ubuntu zip : Upload with fastbootd on phone boot.img as boot-
• From the Droidian zip : Upload with fastbootd on phone vendor.img as vendor, dtbo.img as dtbo, vbmeta.img as vbmeta
• on TWRP format data to remove encryption, and put ubuntu.img in data folder (/data).
  With MTP on TWRP for example (you copy it from you computer and you could find in /data/media. (It could need a reboot to recovery, after a format to see the media folder)
  Or with ADB : adb push ubuntu.img /data/
• Reboot phone
• Enjoy !

The mic sound seem to be lower than Droidian, so a fix could be taken on Droidian.

EDIT : Sorry, we don't have to flash system partition, UBT use the ubuntu.img in /data.

@snailc said in [Poco X3 Pro] Ubuntu Touch - Tutorial/Installation Guide - vayu and Help channel:

so I have Unlock bootloader and rooted the system but when I run

fastboot.exe flash system ubuntu.img

I am getting the following error

Also there is no vendor partition

Hi, Sorry again for my mistake and the delay.

We don't have to flash system partition.

@Vlad-Nirky said in [Poco X3 pro] Need help system not flashing:

@snailc said in Need help system not flashing:

miui version: 12.5.6

On the device page only poco X3 is listed, i don't see poco x3 pro.
https://devices.ubuntu-touch.io/
This device is different, maybe it can use UT...
The miui 12.5.6 is Android 11 and the poco X3 is on halium 10 so need Android 10.

You should ask on the Miatol Telegram page if somebody has already used this device...

https://t.me/UTForMiatoll

Hi !
X3 Pro is not on device page, because we don't have maintainer, maybe I will if UBT choose LVM and I could keep my other OS to.
The port is very good but need few check.

I agree with you, people with Miatoll can help and we have a global X3 Pro Linux group : https://t.me/LinuxForPocoX3Pro

@snailc
Hi !
Sorry dude, we don't have to flash system partition. I try to correct the tutorial.
And sorry for the response time.

Not sure that 12.5.6 is the same as 12.5.9 (for UBT), we replace vendor, but if you have some thing that don't works, you could check to update it.

@Steinmoshe
Yes !

Hi !
It exist a port for X3 Pro, you could see here : https://forums.ubports.com/topic/11334/ubuntu-touch-ubt-tutorial-installation-guide-for-poco-x3-pro-vayu-and-help-channel

If you have time, could you test that works and don't and share it, please ?

Hi !
Is it the good category for this topic ?

Some people like me test UBT on X3 Pro (vayu), a port exist, but not maintained (as I know) so not visible anywhere.
It works well, I test it. It miss some stuff, but have lot that works. I think far as X3 NFC.

If anyone could take time to make inventory, like for X3 NFC.

We have a global Telegram channel for X3 Pro : https://t.me/LinuxForPocoX3Pro and for installing UB T : UBports Welcome & Install help and local UBPorts channel (FR, ES, RU ...)
