Hello.
Thank you for sharing your experience.
Regarding the noise during calls, which Android ROM was installed on the phone before installing UT?

@Lakotaubp
Hello.
Yes, I'll be there on Saturday.

@lolo
I would say that the ROM depends on the Redmi Note 9 Pro model.
The model is usually printed on the back of the phone under Redmi.
This phone has had many variations depending on where it is sold. (Global, Turkey, India, etc.)
The global model is M2003J6B2G and need joyeuse_global_images_V12.0.3.0.QJZMIXM_20210419.0000.00_10.0_global_0801ff7d09

You can get info with
adb shell getprop | grep incremental
adb shell getprop ro.product.name

In fastboot mode (Power and Volume down until Xiaomi rabbit)
fastboot getvar product

Tell us wich model and which phone you have and I'll try to find the right ROM to install before install UT.

@PhAndersson
OK

@PhAndersson
We can arrange a meeting place if you wish.

@AppLee
I'll do, I have a beautifull sweat UBports.
Will have my phone and maybe print some sheets with key features for people interrested in.

@AppLee
I'll try to make myself available to be there on Saturday.

@Ruesaga
I find that these phones work really well with UT. My preferred ROM for the 9 Pro is the joyeuse_global_images_V12.0.1.0.QJZMIXM_20201107.0000.00_10.0_global_eb964f842a
But recommended is 12.0.3

@Ruesaga
I have two Xiaomi Redmi Note 9 Pro.
One for tests (and back up) and one for my daily use. (20.04 several OTA, and actually one on 24.04-1.x Stable and the other under 24.04-2.x)
I have flashed with ubport installer more than 30 times each one.
Starting from the right Android Stock ROM, I never had any problem with any parts of those phones. All is working well.
As UT is talking with Halium (10 in my case) and Halium is talking to previous Android parts left in place during install, the previous Android MUST be the right one. Not near, not another.
Now, I can only refer to my experience...
My FAI device, the mobile network from Orange.

@lolo
If it's global
https://xiaomirom.com/en/download/redmi-10x-4g-note-9-merlin-stable-V12.5.4.0.RJOMIXM/
Choose the Fastboot ROM
But there are specific ROM for models for India, Indonesia, Russia, Turkey, EEA, Global, China.

@lolo
What is the Model of your phone printed at the back?
https://devices.ubuntu-touch.io/device/merlin/

@mrt10001
Any idea?

@projectmoon
Currently, with my Linux PC, I mainly use it as hardware key for KeePassXC.
I know it has NFC capabilities (YubiKey 5 series), so it could be used in the same context or to unlock the session or memory encryption.
I'm just curious to know if other users of this device use it in any way under UT.

Hello.
Has anyone been able to use a YubiKey on Ubuntu Touch?
How could this be done?

Really good!
Thanks again.

@projectmoon

RTFM...
I wasn't aware of this folder.
Actually, that would be a good idea!

@bgriffis
If your RPI has ssh and shared ssh keys
You could create a cron job that would synchronise the file regularly with a script like this

#!/bin/bash

SERVER="192.168.1.18"
USER="vlad"
REMOTE_FILE="/home/vlad/Documents/KeePass/keepassdb.kdbx"
LOCAL_DEST="/home/phablet/Documents/KeePass/"

echo "rsync in progress..."
rsync -avz -e ssh "$USER@$SERVER:$REMOTE_FILE" "$LOCAL_DEST"

@projectmoon
And it's an extraordinary piece of work and a valuable tool in my everyday life!
Thank you for that!

@toniox
Hello.
Normally, installing UT requires Android to be installed first.
Do you think this is possible given the state of the phone?

@projectmoon
Hello.
Oh, good news.
Do you have any documentation explaining how it works in detail?
I thought the BT connection could be established directly.
I'll also look into it on my end.
Oh, okay, you need a LoRa device to propagate the signal.
And the BT connection is used to connect to it...
I'm new to these technologies, but it's clearer now.
Do you have any hardware recommendations for these devices to get started (or a link to them)?
